Legion of Super-Heroes (comics)/Characters

Useful Notes on Legion Continuity:

The Legion of Super-Heroes has been ongoing in one form or another since 1958, encompassing three completely distinct continuities and several more "branch" continuities. That being the case, there are many alternate versions and a lot of Character Development involved, and what tropes apply to what characters varies from version to version. Here's a thumbnail reference for what refers to what part of continuity:

"Preboot--The original continuity, prior to the 1994 Zero Hour continuity reboot. These stories take place on Earth-1 (Pre-Crisis) or Earth-0 (current continuity).

V4 / 5YL / TMK--"Five Years Later", the fourth volume of the Preboot title, a Darker and Edgier continuation following (as the title suggests) a five-year Time Skip. The 5YL stories were mostly written by Tom and Mary Bierbaum and drawn by Keith Giffen, usually abbreviated to "TMK".

Softboot / Glorithverse--The state of Legion continuity after a Cosmic Retcon unleashed during V4 to write the Pocket Universe Superboy out of continuity. Glorith was a time-controlling villainess who took advantage of the retcon.

Batch SW6--One of the most significant ongoing storylines from 5YL, involving a group of time-paradox duplicates of the early Legion (who went on to star in the Spin Off Legionnaires until Zero Hour). The term comes from the cryptic labels of the People Jars the duplicates were found in.

Retroboot / Deboot / Johnsboot--The version of the original continuity Legion that appeared starting in 2007's "The Lightning Saga", branching off from the Preboot continuity just before 5YL, except that Superboy didn't die. So named because its tone was set by writer Geoff Johns."

"Postboot--The continuity following the 1994 Zero Hour reboot, up until it was rebooted again in 2004. These stories take place on Earth-247.

Archie Legion--The relatively lighter initial portion of the Postboot.

DnA--The Darker and Edgier "Legion of the Damned" and "Legion Lost" stories by Dan Abnett and Andy Lanning."

"Threeboot--The continuity following the 2004 reboot, re-envisioning the Legion as a rebellious youth movement in a stagnant society. These stories take place on Earth-Prime."

"L3W--Legion of Three Worlds, a Final Crisis limited series bringing together the Retroboot, Postboot, and Threeboot Legions."

The version of the Legion currently appearing in comics is the "Retroboot" based on the original "Preboot" continuity, described above.

Characters below are listed in the era in which they were introduced, not when they joined the Legion. For instance, Night Girl was introduced in the 1960s but didn't become a full member until 2007, while Kid Quantum was introduced in 1990 but Retconned into being a member during the Silver Age era.

The Animated Adaptation has its own main page and character sheet.

Cosmic Boy/Polestar
"AKA: Rokk Krinn

Homeworld: Braal

Abilities: Magnetism manipulation"

In most incarnations, the leader of the Legion. Cosmic Boy's serious demeanor and respect for authority lends him to the role of leadership, but places him at odds with Lightning Lad. Preboot, his brother was Pol Krinn, aka Magnetism Lad. His personality, like his power, is magnetic--he draws people to his cause with his charisma.

In the FYL continuity, Cosmic Boy was De Powered during a war between Braal and Imsk. He married Night Girl and had a son named Pol after his late brother. Shortly before his reality was destroyed by Zero Hour, he regained his powers thanks to a pair of power gauntlets and took the name Polestar.

Postboot, Cosmic Boy was a sports star whose talent helped him as a superhero. When half the team was stranded in the present day, Cos led them through Final Night and Genesis and was instrumental in getting them home. When the Postboot Legion's Earth was destroyed in Infinite Crisis, he continued to lead them, and in their current exile as the Wanderers, he is leading them in their search for a new home.

In Threeboot, though Cosmic Boy founded the Legion, he was widely disliked because he was forced to accept supervision from the United Planets. He struggled with command, and after the Dominator War, ceded leadership to Supergirl. He was approached by a group of superheroes from the 41st century whose legacy he inspired and joined them in the future.


 * Batman Gambit
 * Blue Oni: To Lightning Lad's Red Oni.
 * The Cape
 * The Chains of Commanding
 * Chick Magnet: Har, har.
 * Convenient Coma: After half the postboot Legion gets thrown into the 21st century.
 * Extra Ore Dinary
 * Fan of the Past
 * The Hero
 * The Kirk
 * Not Himself
 * Oblivious to Love
 * The Plan
 * Power Trio: As the ego, with Lightning Lad (id) and Saturn Girl (superego).
 * Rousing Speech
 * Standardized Leader
 * Stripperific: His costumes in the Grell era. Admittedly, so were most of the other characters' costumes at the time, but Cosmic Boy's Rocky Horror-esque corset and Saturn Girl's bikini (see below) are the best-remembered.
 * Three Amigos: With Lightning Lad and Saturn Girl.

Saturn Girl
"AKA: Imra Ardeen

Homeworld: Titan

Abilities: Telepathy"

A telepath from one of Saturn's moons, Saturn Girl is the glue that holds the Legion together, keeping a balance between the cool-headed Cosmic Boy and Hot Blooded Lightning Lad. When Cos isn't the Legion's leader, it's usually her. In all incarnations of the Legion, the love of her life is Lightning Lad.

In Threeboot, Saturn Girl's people were so reliant on telepathy that their vocal cords were useless. She was distant and reserved. Her mother was a member of the United Planets council, which put her at odds with the more iconoclastic Legionnaires.


 * Happily Married: With Lightning Lad, Preboot. Following Legion of 3 Worlds in the Retroboot continuity, Imra and Garth went back to this in the latest Legion volume.
 * Hollywood Pudgy: Her Threeboot counterpart, along with Threeboot Invisible Kid. Francis Manapul redesigned her as being somewhat "hippy" with a little more weight then the other girl Legionnaire, but she is in no way fat or chubby. One of the complaints she has about herself is that people consider her "dumpy". Ultra Boy, in an attempt to make her feel better while she's in a rut with Lightning Lad, says "you're sexy for a dumpy chick".
 * The Lancer or The Chick
 * Mama Bear: Preboot/Retroboot. This woman went up against Darkseid to restore one of her sons to normal. Unless you want to end up as a mindless heap on the floor, do not mess with her kids.
 * Mind Over Manners: Generally observed, although Postboot!Saturn Girl has had a few memorable, if accidental lapses. Like telepathically animating a comatose Cosmic Boy to help keep the Legionnaires trapped in the past together--and turning him into her Relationship Stu. Then in Legion Lost, Imra used her psychic powers to make Ultra Boy think that his wife, Apparition, was with them in their deep-space exile, and when he found out, he was pissed.
 * Official Couple: With Lightning Lad. Various attempts at shaking it up have proven futile and/or unpopular.
 * Oh God Did She Just Hear That
 * Pink Girl Blue Boy: The pink girl to Lightning Lad's blue boy. However, she's also been known to wear red instead of pink.
 * Power Limiter: Postboot. It comes off.
 * Power Trio: As the superego, with Cosmic Boy (ego) and Lightning Lad (id).
 * Telepathy
 * Journey to The Center of The Mind
 * Living Lie Detector
 * Mind Probe
 * People Puppets: notably in the postboot era, when Cos is in a coma.
 * Telepathic Spacegirl
 * Three Amigos: With Lightning Lad and Cosmic Boy.
 * Well Intentioned Extremist: Preboot, during a Silver Age story where she rigged an election for leader, secretly stole her teammates abilities, and then had them suspended for arbitrary reasons. It turned out she did all that in order to spare her teammates from fighting in an upcoming battle with an alien overlord, where a member would've surely been killed. Her plan failed when Lightning Lad discovered what she was planning, and sacrificed himself in battle.

Lightning Lad/Live Wire
"AKA: Garth Ranzz

Homeworld: Winath

Abilities: Electrical generation and direction"


 * Artificial Limbs: Loses an arm in most continuities, though what it's from varies wildly.
 * Back From the Dead: Came Back Wrong in 5YL. He also returned from a Heroic Sacrifice near the end of the Postboot continuity, inhabiting Element Lad's crystallized body.
 * Red Oni: To Cosmic Boy's Blue Oni.
 * Brainwashed and Crazy: When he became Starfinger, Preboot.
 * Cain and Abel: With Lightning Lord.
 * Grand Theft Me: Postboot, Livewire eventually became trapped in Element Lad's body.
 * Half Identical Twins: With Lightning Lass.
 * Happily Married: With Saturn Girl, Preboot. Following the end of Legion of 3 Worlds and the beginning of the latest Legion series by Paul Levitz, Retroboot Garth and Imra have gone back to this.
 * Heroic Sacrifice: Several times in several continuities.
 * Hot Blooded: In later continuities.
 * House Husband: The Preboot version, while his wife went back to being a Legionnaire, Garth was the one willing to stay at home and look after their twin sons, Graym and Garridan.
 * Jerk Jock: The SW6 version.
 * Hidden Heart of Gold: The SW 6 version is arguably the meanest of all the alternate Lightning Lads, at one point punching SW 6 Cosmic Boy in the face because he thought he was coming on to Saturn Girl. A Lotus Eater Machine experience revealed, however, when he was young he accidentally killed his pet and felt insanely guilty about it. His parents saying they could easily replace it and tossed it away didn't make him feel better.
 * The Lancer to Cosmic Boy's Hero, when Saturn Girl isn't filling the role instead.
 * The McCoy
 * Official Couple: With Saturn Girl. Attempts to shake this up don't generally end well or popularly.
 * Papa Wolf: Don't mess with this man's sons, not unless you want your synapses scrambled.
 * Perma Stubble: His Retroboot counterpart was consistently depicted with stubble until the beginning of the new Legion series.
 * Pink Girl Blue Boy: The blue boy to Saturn Girl's pink girl.
 * Power Trio: As the id, with Cosmic Boy (ego) and Saturn Girl (superego).
 * Redheaded Hero
 * Shock and Awe
 * Three Amigos: With Cosmic Boy and Saturn Girl.
 * Understanding Boyfriend: His Pre-Crisis counterpart, in contrast to his counterparts, especially his SW 6 counterpart.

Bouncing Boy
"AKA: Chuck Taine

Homeworld: Earth

Abilities: Inflatable body, invulnerability (Preboot); expert mechanic (Postboot)"


 * Acrofatic
 * Big Beautiful Man: Artists have drawn him with a fair amount of muscle over the years, making him appear beefy instead of simply fat. And even without that, fans find him attractive and utterly adorable.
 * Demoted to Extra / Ascended Extra: Like Matter-Eater Lad, Chuck was deemed too silly for the Postboot Legion, so he was recast as a non-powered mechanic contracted to the Legion. However, he proved popular, so during the DnA era he was promoted to "Chief Engineer" and joined the main cast... with his rather unique spaceship, the Bouncing Boy.
 * The Everyman
 * Exactly What It Says On the Tin
 * Fridge Logic: Preboot. It would appear his power to inflate into a ball is the reason why he appears overweight, and this was justified by the Silver Age issues when he lost his bouncing power (the first time). He became so svelte his teammates refused to believe it was him. However, in his origin story, he's depicted as looking just as tubby as he did after he could inflate into a ball. Future stories supported the fact that his power had nothing to do with his weight.
 * Happily Married: To Luornu, preboot and retroboot. They were the first Legionnaires to get married.
 * Hyper Destructive Bouncing Ball: He IS one.
 * Lethal Joke Character: As pointed out elsewhere on the wiki, a 200+ pound weight that can fling itself around the room at remarkable speed is pretty dangerous.
 * Mr. Fixit: Postboot was too serious for Bouncing Boy, so it had Chuck Taine as the Legion's resident mechanic/engineer.

Brainiac 5/Brainiac 5.1
"AKA: Querl Dox

Homeworld: Colu

Abilities: 12th level super intelligence; force-field projection (Postboot only)"


 * Ambiguously Gay Bisexual: Postboot Brainy shows attraction to both Andromeda and Invisible Kid.
 * Barrier Warrior: Wears a belt that projects an impenetrable forcefield around himself; can sometimes extend the field to do more creative things with it.
 * Brains and Brawn: With Supergirl, Preboot.
 * Deadpan Snarker
 * Deflector Shields: He usually has one on his belt.
 * Flat Earth Atheist
 * Gadgeteer Genius
 * Insufferable Genius: More often than not, depending on the writer. In the postboot continuity, he's so fed up with the other Legionnaires pestering him for help that
 * This is most apparent in Legion of Three Worlds, where Retroboot, Postboot, and Threeboot Brainy all have to work together and just can't stop arguing.
 * May December Romance: His Retroboot counterpart during New Krypton is still in love with Supergirl, even though, at that point in time in the 21st Century, she's still a teenager and he's an adult. Of course, Querl doesn't admit this to Kara because she had yet to actually join the Retroboot Legion.
 * Missing Mom: In Postboot, it turned out that Brainy was traumatized by the memory of his mother, Brainiac 4, abandoning him just as soon as she'd finished giving birth. Brainiac 4 was a statuesque blonde woman, by the way.
 * Nice Job Breaking It Hero: The many times when one of Brainy's creations becomes a problem for the entire Legion (see: Computo).
 * Non Action Guy: Depending on the continuity. He's always preferred to be mission control, but in some (especially Preboot) he can still pack a hell of a punch.
 * Science Hero
 * Science Related Memetic Disorder: Goes crazy with remarkable frequency.
 * The Smart Guy
 * The Spock
 * Straw Vulcan
 * Stuff Blowing Up: In some continuities, the frequency with which his experiments explode is a Running Gag.
 * Summon Bigger Fish: Notably employed against the Time Trapper.
 * Technopath
 * Teen Genius
 * Wonderful Life: He's subjected hilariously to a Wonderful Life plot in a side story in one of the Postboot issues. When it appears that everyone else really would be better off without him, he decides he would rather go on existing just to make them miserable.
 * Writing Around Trademarks: after DC introduced Brainiac, the makers of a toy computer called "The Brainiac" complained. DC had to place a trademark notice for the toy computer in the comic, and made Brainiac a robot with a computer mind. This made things complicated for Brainiac 5, who could not be a descendant of Brainiac and was retconned as the descendant of a humanoid who Brainiac adopted and who later rebelled. The animated version simply made Brainiac 5 and all Coluans robots, with Querl based on the original's code. In 2008 (the original change was in 1964), Brainiac was retconned back into being a living Coluan making this moot.
 * Year Inside Hour Outside: His Glorithverse counterpart. During an Annual which acted as a recap of events in Legion history altered to fit the new continuity, Glorith kissed Brainiac 5 for a few seconds after he discovered that she'd been manipulating the Legion the whole time. Due to her time manipulating abilities she made the kiss last an eternity, effectively driving him insane in order to make him forget this revelation.

Chameleon Boy/Chameleon
"AKA: Reep Daggle

Homeworld: Durla

Abilities: Shapeshifting"


 * Cloudcuckoolander: His Threeboot counterpart.
 * Luke I Am Your Father: In Preboot, it turned out that Reep was the son of R.J. Brande, who was actually a Mode Locked Durlan.
 * Magic Pants: In Threeboot, after his teammates get new uniforms, Cham decided to alter his costume's design. That's when it dawns on Star Boy that Cham's costume is a part of his body, meaning he's been walking around naked the entire time.
 * Older and Wiser: In the Five Years Later continuity, Cham becomes the mentor to the younger "Batch SW6" Legionnaires.
 * Voluntary Shapeshifting
 * Shape Shifter Baggage
 * Shapeshifting Squick: Given a nod in Threeboot, in which one character suggests that Chameleon is not attracted to non-shapeshifters.
 * Master of Disguise: Obviously.
 * You No Take Candle: Early in Postboot, when he's just learning to speak Interlac. And kept up much longer than necessary as a form of Obfuscating Stupidity.

Chemical King
"AKA: Condo Arlik

Homeworld: Phlon

Abilities: Can alter the speed of chemical reactions"


 * Demoted to Extra: The Postboot Condo Arlik is a TV reporter, not a superhero.
 * Race Lift: In Postboot, he's depicted with tan skin, whereas Preboot he was Caucasian.
 * Sacrificial Lamb
 * We Hardly Knew Ye
 * What Kind of Lame Power Is Heart Anyway: He worries about this in-story, despite his powers actually being pretty useful.

Colossal Boy/Leviathan/Micro Lad
"AKA: Gim Allon

Homeworld: Earth (Preboot/Threeboot); Mars (Postboot)

Abilities: Giant growth"


 * Attack of the 50 Foot Whatever
 * Bait and Switch Tyrant: Although he was portrayed as being out of his depth as the Legion's leader without Cosmic Boy advising him, he never quite crossed the line into full Umbridge-ness.
 * Composite Character: Threeboot Micro Lad is a combination of Preboot Colossal Boy and supervillain Micro Lad.
 * Gentle Giant
 * Happily Married: to a shapeshifting Green-Skinned Space Babe, at that.
 * Martyr Without a Cause: In Postboot, his "heart's desire" is to die to save the lives of his teammates (It Makes Sense in Context - see My Greatest Failure, below).
 * Which inspired one Elseworlds, "Superboy's Legion", to feature him doing just that - dying in the fledgling Legion's first encounter with the Fatal Five.
 * My Greatest Failure: In the Postboot, he was appointed the Legion's leader for one mission that ended in the death of Kid Quantum; he immediately abdicated in favor of Cosmic Boy and never forgave himself. (See Martyr Without a Cause, above.)
 * My Name Is Not Durwood: Threeboot, he insists he's Micro Lad, not Colossal Boy, because he's a giant who can shrink to normal human size, not a normal human who can grow giant.
 * The Neidermeyer: In the Postboot, Leviathan was introduced as one of these (since he was a former Science Policeman in that continuity). The Haughty is soon Broken.
 * Sizeshifter

Dream Girl/Dreamer
"AKA: Nura Nal

Homeworld: Naltor

Abilities: Precognition"


 * BBW: In 5YL.
 * Dreaming of Things to Come
 * Fainting Seer: Postboot, she literally only gets visions in her dreams, but visions can strike at any time, resulting in narcolepsy- until she gets over it via Training From Hell which results in her no longer sleeping. Ever.
 * Ms. Fanservice: by design, from her very first appearance.
 * Obfuscating Stupidity: Her flirtatious persona makes her easy to underestimate; this is generally a mistake.
 * Prophecy Twist / Prophetic Fallacy
 * Took a Level In Badass: Postboot; see above. In original continuity and Threeboot she can use her shorter-range precognition to predict opponents' moves in battle, and even uses this to take out two Naltorian cops who've been trained in the same skill.
 * What Kind of Lame Power Is Heart Anyway: Being well aware of the limits of her power, she became a Renaissance Woman in order to be useful to the team.
 * White Haired Pretty Girl

Element Lad/Alchemist/The Progenitor
"AKA: Jan Arrah

Homeworld: Trom

Abilities: Capable of transmuting the elements"


 * A God Am I, Blue and Orange Morality, Humanoid Abomination: "Legion Lost"
 * Apocalypse How: Varies. Preboot, a greedy space pirate/marauder exterminates the Tromians before we meet Jan. Postboot, we meet Jan, Jan's dad, and Jan's whole town before getting to watch four Daxamites with the powers of Superman simply roast the planet with heat vision. Threeboot, mention is made obliquely of Jan being the only survivor of a genocide by the Daxamites, now a dead race themselves.
 * Brainwashed and Crazy: Postboot Jan is kidnapped and brainwashed into becoming the Postboot Starfinger.
 * Cloudcuckoolander: Postboot.
 * Go Mad From the Isolation\Showing Off the Perilous Power Source: "Legion Lost".
 * Hair of Gold: Sometimes even literally, once his Postboot version starts playing around with transmuting himself.
 * Hour of Power: Unlike his counterparts, Threeboot Element Lad's transmutations only last for sixty seconds.
 * Last of His Kind: Every time (spell his home planet's name backwards, why don't you?). See Apocalypse How, above.
 * Martial Pacifist: Some continuities have him as a deeply religious man who only uses his transmutation powers in nonviolent ways- and it's easy to see why, once Leviathan suggests that he just "turn the Fatal Five into Cheez Whiz".
 * Odd Friendship: His Postboot version with Monstress. He was often seen complimenting her on her appearance and wardrobe without appearing to be hitting on her, but from the way they interacted with one another there appeared to be potential for a romantic relationship.
 * Time Abyss: In "Legion Lost".

Ferro Lad/Ferro
"AKA: Andrew Nolan

Homeworld: Earth

Abilities: Can turn into living iron, gaining super-strength and invulnerability"


 * Backup Twin: His brother Douglas.
 * Chrome Champion
 * Continuity Nod: The Preboot Ferro Lad is best known for sacrificing his life to stop a Sun-Eater. The Postboot Ferro first appears during the Final Night crossover, featuring another Sun-Eater, and offers to give his life to stop it, but is quickly told, "That's OK, son, but you've got too much to live for," and Hal Jordan stops it instead.
 * Facial Horror: Why he always wears a mask. We never get to see it, but Postboot he looks for medical treatment and is told that notonly is his skull structure sprocked up beyond repair, but his muscle and skin tissue are mixed in with it at random. The only help possible would come from a metallurgist and require him to remain metal for the rest of his life, sacrificing most of his senses of smell, taste, and touch. He still considers it for a while before deciding to keep his fleshy form. Later, he was just starting to accept his appearance when he was wounded and Mode Locked into metal form- with the mask on.
 * Fridge Logic: It was revealed that the Postboot Legion was actually the Legion from an alternate Earth, Earth-247. However, the Postboot version of Ferro and his brother both came from the 20th Century of New Earth, which is now revealed to be the Earth home to Retroboot Legion. This raises the questions of how two separate versions of Ferro Lad, and his/their brother(s), could exist in the same universe one thousand years apart?
 * Heroic Sacrifice: Preboot. Postboot, he had a twin brother who died protecting him and some of the timelost Legionnaires under unrelated circumstances.
 * Made of Iron: Literally.
 * Missing Mom: Postboot, he and his brother were abandoned by their mother and locked up with a number of other metahumans for experiments by a corrupt government-sponsored scientist.
 * More Expendable Than You / More Hero Than Thou
 * Nice Guy
 * Parental Abandonment: Postboot.
 * Percussive Prevention
 * Shapeshifter Mode Lock: Postboot. He was mortally wounded by a criminal and only stayed alive by morphing to iron form, forcing him to remain "ironed up" permanently.
 * Someone Has to Die: Preboot.
 * What Could Have Been: Jim Shooter wanted to make Ferro Lad African-American, but the editors were worried that they'd lose distribution in the South. So Shooter decided to have him heroically sacrifice himself.

Green Lantern
"AKA: Rond Vidar

Homeworld: Earth

Abilities: Green Lantern power ring"


 * Killed Off for Real: in Legion of Three Worlds
 * Sacrificial Lion: A variation where the character himself has been around for a long time, but his new role as a Legion member came just before his death--he was first revealed to be a member in Legion of Three Worlds, where he was killed. Previously he was only an honorary member, and he had only had the ring for a brief time.

Invisible Kid I
"AKA: Lyle Norg

Homeworld: Earth

Abilities: Invisibility"


 * Gadgeteer Genius: In the Postboot continuity, Brainy was more the pure scientist, doing things like creating antigravitic material as a side effect of an experiment, and Lyle was more the engineer, doing things like taking said metal and producing flight rings from it.
 * Hollywood Pudgy: Slightly, in the Threeboot continuity. Francis Manapul made it a point to design Lyle as a bit round and less of a typical skinny kid. This is averted when other artists pencilled issues during Jim Shooter's run, but in the issues that Manapul did illustrate, after the Legion gets new uniforms, one can note that Lyle's belly sticks out a bit.
 * Invisibility: Threeboot amps up the power by making him undetectable even by the most advanced tech.
 * Naive Newcomer: Threeboot's first arc is told almost entirely through his perspective and is about how alien everything is to him.
 * New Meat: Threeboot again.
 * Professor Guinea Pig: See Super Serum, below.
 * Science Hero
 * Super Serum: The source of his powers. In the Threeboot, he gives the serum to the Science Police in exchange for them leaving the Legion alone- but not before somehow encoding it with a virus that gives the Legion a backdoor into SP computers after it's analyzed.
 * Teen Genius: Threeboot Brainy goes so far as to say that Lyle's plan involving the virus mentioned above was the cleverest thing a human had done since the discovery of fire.
 * Teen Superspy: Postboot, this was his pre-Legion job, and he goes on to found the Legion Espionage Squad with Triad, Apparition, Shrinking Violet, and Chameleon. He also leads the Squad in most continuities where it exists.
 * The Everyman: Threeboot has him as an obvious audience identification character.
 * Word of Gay: Postboot.

Karate Kid
"AKA: Val Armorr

Homeworld: Earth

Abilities: Martial arts master"


 * Badass Normal: No version of Karate Kid has ever had an actual superpower. No version of Karate Kid except the one from the animated series has ever had any trouble with the Legion's traditional requirement that all members have an intrinsic superpower. The first version of the character accomplished this by proving he could stand up to no less than Superman himself.
 * Charles Atlas Superpower
 * Fad Super: An unusual case because he is a preexisting character who became one for a while long after he was introduced. In the 1970's, he was suddenly modelled after Bruce Lee (and drawn Asian), given a robe instead of a superhero costume, and spun off into his own series which was sold as a martial arts series until the martial arts fad died out. Also, note that the movie The Karate Kid came out decades after his premiere - the credits actually mention that DC Comics owns the rights to the name. (Unfortunately, in-universe he debuted a thousand years later, which leads to silly jokes being made every time he meets someone from the 21st century.)
 * Heroic Sacrifice
 * Race Lift: Started out Caucasian and has been Race Lifted back and forth to and from Asian a couple times.
 * Writer On Board: Keith Giffen really does not like Karate Kid, and has said up-front that any time he ends up writing the Legion he will kill off the character, as he did in 1984. (To Giffen's credit, he gave the the character an appropriately badass exit saving his wife's planet from the Legion of Super-Villains in a story arc that's remembered fondly by many fans.)

Lightning Lass/Light Lass/Gossamer/Spark
"AKA: Ayla Ranzz

Homeworld: Winath

Abilities: Electrical generation and direction (as Lightning Lass/Spark); gravity manipulation (as Light Lass/Gossamer)"


 * Bi the Way: Her Preboot and FYL counterparts were both heavily implied to be in relationships with Shrinking Violet. Following the Retroboot, it appeared that she had gotten back together with Timber Wolf, but her relationship with Violet appears to have been brought back in the recent Legion annual.
 * Cain and Abel: Not to the degree of Garth and Mekt, but she isn't fond of her lunatic brother to say the least.
 * Distaff Counterpart
 * Lightning Can Do Anything: Like restore your old powers, for example.
 * Gravity Mistress: As Light Lass/Gossamer, she can make objects lighter.
 * Half Identical Twins: With Lightning Lad.
 * Plucky Girl
 * Really Gets Around: Exaggerated into this in Threeboot.
 * Shock and Awe: As Lightning Lass/Spark.

Magnetic Kid
"AKA: Pol Krinn

Homeworld: Braal

Abilities: Magnetism manipulation"


 * Always Someone Better
 * Extra Ore Dinary
 * Heroic Sacrifice
 * Killed Off for Real

Matter-Eater Lad
"AKA: Tenzil Kem

Homeworld: Bismoll

Abilities: Matter consumption"


 * Adam Westing: A fictional version. By the time of the FYL Legion, Tenzil had gained a rock star persona and reveled in the ridiculousness of his power. He's a senator on Bismoll and a star of multiple TV shows, which he used to his advantage to get Polar Boy out of jail by having his trial televised and utterly owning the Dominator-controlled Earthgov.
 * Casanova Wannabe: The SW6 version.
 * Cool Shades: In FYL, Postboot, and Threeboot. In the latter, his shades have a built-in camera and lie-detector.
 * Darker and Edgier: The Threeboot version. He bit a guy's finger off.
 * Demoted to Extra: As with Bouncing Boy, Postboot was too down to earth for a guy with powers like his, so he became the Legion's cafeteria chef. Threeboot, he's a lawyer who searches for Cosmic Boy alongside the Legion- seeking to arrest him for war crimes.
 * Fun Personified: In FYL and Postboot.
 * Ho Yay: With Mon-El in "New Krypton".
 * Driven to Madness: By eating the Miracle Machine.
 * Extreme Omnivore
 * Obstructive Bureaucrat: The Threeboot version.
 * Put On a Bus: After he ate a cosmic "Miracle Machine", M-E Lad went insane and was returned to his home planet. This was because the writers thought he was too silly and wanted to get rid of him without killing him.
 * Team Chef: In Postboot.
 * Temporary Bulk Change: In a Preboot Silver Age issue involving the Legionnaires trapped in a prison camp for superheroes, M-E Lad was hit by a ray that slowed down his Bismollian metabolism to that of a normal human, thereby making it impossible for him to eat anything anymore. He had previously eaten about a ton of dirt in order to form an escape tunnel, so when his metabolism slowed down he swelled to the size of a balloon.

Mon-El/Valor/M'Onel
"AKA: Lar Gand (Bob Cobb, Jonathan Kent)

Homeworld: Daxam

Abilities: Super-strength, speed, senses, flight, and invulnerability"


 * Secret Identity: Postboot, Valor is a religious figure due to having seeded intelligent life on most of the worlds the Legion hails from, and when they manage to release him from the Phantom Zone, there's very nearly all sorts of riots over different races' beliefs regarding the legendary hero. They manage to get him out in secret, though, and eventually he takes the name M'onel as his new identity.

Night Girl
"AKA: Lydda Jath

Homeworld: Kathoon

Abilities: Superhuman strength, activated in darkness"


 * Ascended Fangirl: She was a member of the Legion of Substitute Heroes and idolized Cosmic Boy to the point of being a stalker. As the Super Dickery of the Silver Age was quietly downplayed, she became Cosmic Boy's long-time girlfriend. She only became a Legion member recently after a long stint as a supporting character.
 * Super Strength
 * Weaksauce Weakness: She's super-strong and Nigh Invulnerable... as long as she's not in sunlight (Kathoon is a rogue planet).

Phantom Girl/Apparition/Phase (Tinya Wazzo)
"AKA: Tinya Wazzo

Homeworld: Bgztl

Abilities: Intangibility"


 * Absolute Cleavage: A cleavage cut-out in her Grell-era costume, along with...
 * Awesome Anachronistic Apparel: ...bell-bottoms and...
 * Girlish Pigtails: In the Grell era outfit again. This was one of the longest-lived of the Cockrum costumes, and the Threeboot used a variation of this costume.
 * Continuity Snarl: During the TMK era, Tinya was killed in front of Ultra Boy; about the same time, L.E.G.I.O.N. had an amnesiac Bgtzlian from the future--"Phase"--suddenly appear, with the obvious implications. However, Jo and Tinya were reunited shortly before the first reboot, while "Phase" was revealed to be Tinya's long-lost sister "Enya". After the reboot, "Enya" never existed... so it turned out that Tinya was half-Carggite (Triad's race), and her illegitimate father secretly abducted and sold her other two selves before anyone found out--and one of them became Phase, who merged with the then-bodiless Tinya while she was trapped in the 20th Century. Not quite as bad as Wonder Girl, and the Threeboot swept the whole thing under the table, but still...
 * Intangible Woman
 * Official Couple: With Ultra Boy.
 * Rebellious Princess: In Postboot, she's the daughter of her planet's ambassador and earns her way into the Legion virtually as soon as they're announced to the world for helping to defeat a terrorist attack on the United Planets. Her mother's not pleased with either this or her romance with Ultra Boy.
 * Spirit Advisor/Not So Imaginary Friend: Tinya became this for Jo in Postboot, after she was incinerated by the White Triangle. She got better.
 * Shapeshifter Mode Lock

Polar Boy
"AKA: Brek Bannin

Homeworld: Tharr

Abilities: Cold control"


 * An Ice Person
 * Artificial Limbs
 * Ascended Fanboy
 * Handicapped Badass: In Retroboot, Polar Boy's arm was ripped off by Earth-Man. He replaced with a prosthetic made of ice that he animates with his powers.
 * Took a Level In Badass: Retroboot.

Princess Projectra/Queen Projectra/Sensor Girl/Sensor/Imperiatrix
"AKA: Projectra Wind'zzor (Preboot); Jeka Wynzorr (Postboot); Projectra Vauxhall (Threeboot)

Homeworld: Orando

Abilities: Illusion casting; mind control and super-strength (Threeboot only)"


 * Biological Mashup: Near the end of Postboot, she was mutated into a naga-like form.
 * Charlie Brown From Outta Town: Preboot, when she secretly returned from retirement as "Sensor Girl."
 * Face Heel Turn: Threeboot.
 * Intellectual Animal: Postboot, Jeka Wynzorr is a giant snake.
 * Master of Illusion
 * Psychic Powers
 * Rich Bitch: Threeboot, in the Shooter run.
 * Royals Who Actually Do Something: She's the actual princess (later queen) of planet Orando.
 * Super Senses: Appropriately enough, she demonstrates these as Sensor Girl.
 * Unstoppable Rage: After he kills her consort Karate Kid, Projectra scares the crap out of Nemesis Kid, and breaks his neck with her bare hands.
 * What Could Have Been: Originally, Supergirl was going to be revealed to be Sensor Girl, having come back from the dead with her Kryptonian sensory powers enhanced.
 * White Haired Pretty Girl

Shadow Lass/Umbra
"AKA: Tasmia Mallor, Betsy Norcross

Homeworld: Talok VIII

Abilities: Generate absolute darkness"


 * Casting a Shadow
 * Dark Is Not Evil
 * Proud Warrior Race Girl: Tasmia's origin lies somewhere between "native powers" and "unique powers", in that she is the "Shadow Champion" of Talok VIII. In some continuities, this means that all Talokians have these powers and she's officially the best at using them in combat; in others (Postboot particularly), she's officially the best in combat among Talokians, and that earns her the right to her powers. The latter scenario turns out disadvantageous in Postboot when she's missing and presumed dead by her people and they appoint a new champion.
 * Royals Who Actually Do Something: In some continuities, "Shadow Champion" is a hereditary position, making her akin to a princess or queen who is officially required to kick ass.
 * Ship Tease / What Could Have Been: Upon her introduction in Postboot, her narration briefly mentioned an attraction to M'Onel. They had been a long-standing couple in Preboot, but nothing came of it.
 * What Does She See in Him: Her Retroboot counterpart has broken up with Mon-El and entered into a relationship with Token Evil Teammate Earth-Man. Tasmia tries to justify this in that he is a warrior befitting of her race, but her teammates aren't exactly buying it.

Shrinking Violet/Virus/Veye/LeViathan/Atom Girl
"AKA: Salu Digby

Homeworld: Imsk

Abilities: Able to shrink to microscopic size; giant growth (Postboot only)"


 * Alternate Me Scares Me: Batch SW6 Salu is intimidated by her tougher, more bitter 5YL counterpart, at least until she gets to know her better.
 * Heroic Sociopath: Threeboot.
 * Legacy Character: Postboot Salu changes her codename to "Leviathan", or more accurately "LeVIathan" after gaining Gim Allon's powers alongside her own in the aftermath of the "Emerald Vi" debacle.
 * Les Yay: With Light Lass in Preboot (implied to actually be a relationship) and Kinetix in Postboot (exclusively fan speculation about crushes).
 * Locked Into Strangeness: Salu picks up a lock of green hair in the aftermath of being freed from the Emerald Eye.
 * Shrinking Violet
 * Sizeshifter
 * With Great Power Comes Great Insanity: Postboot Vi after she bonds with the Emerald Eye, especially after she accidentally causes Leviathan's death with it.
 * Evil Costume Switch
 * Gollum Made Me Do It
 * More Than Mind Control: The Eye actually influences her personality slowly over time.

Star Boy/Starman VIII
"AKA: Thom Kallor (Danny Blaine)

Homeworld: Xanthu

Abilities: Gravity manipulation"


 * The Ace: Postboot only.
 * Foregone Conclusion: Invoked but averted. Postboot Star Boy learns that the Starman that succeeded Jack Knight in the 21st century is him in his future, but Jack tells him that the future can always change. Lo and behold, the future Starman later turns out to be Retroboot Star Boy instead.
 * Gravity Master: Most versions of the character could only make things heavier. The Retroboot version can also make things lighter.
 * Legacy Character: Retroactively. Though not originally conceived as such, later continuity connected him to the Starman mythos.
 * Never Live It Down: In-universe example: the Postboot Star Boy crashed a spacecraft once, so all his friends thought he was a terrible driver.
 * Race Lift: The Threeboot version is black; all others are white.
 * Superpower Lottery: Postboot, Star Boy manifested Super Strength, Super Speed, Nigh Invulnerability, and Lightning Vision, from (unbeknownst to anyone) eating Space Whale flesh. These extra powers faded after the battle against Mordru.
 * This was also true in preboot/current continuity. Star Boy's first appearance showed him having many powers, while his later appearances showed the gravity powers. This was explained away with a story explaining that he had had the gravity powers from birth and the others were temporary.
 * Weaksauce Weakness/Bizarre Alien Biology: In threeboot, he's more or less diabetic because people from Xanthu can't break down sugars properly. Unlike most Weaksauce Weaknesses, this is only mentioned in a throwaway scene and never actually used against him.

Sun Boy/Inferno I
"AKA: Dirk Morgna

Homeworld: Earth

Abilities: Solar energy generation and manipulation"


 * Brought Down to Normal: Retroboot Sun Boy lost his powers not long before Lo 3 W
 * Face Heel Turn: In 5YL, Sun Boy becomes a willing pawn of the Dominators.
 * Chest Insignia
 * Chick Magnet
 * Demoted to Extra: Postboot, though he still gains his solar powers (albeit for only a short time, and less controllable- while he has them, he glows so brightly that he needs a tinted transuit to keep from blinding or burning people).
 * Gender Flip: Subverted--a female Inferno appears on the WorkForce in the Post-Zero Hour continuity, but she turns out to be a different person than Dirk Morgna.
 * Handsome Lech
 * Heroic BSOD: Retroboot, after he's imprisoned and tortured by Earth-Man. He gets better after seeing his Threeboot counterpart get murdered by Superboy-Prime.
 * Playing With Fire
 * Redemption Equals Death: His Five Years Later counterpart decided to finally do some good, only to have the people of Earth reject him for being a sell-out. He's then caught in a nuclear blast and his powers are warped to the point that he's rendered a perpetually burning corpse until his lover Circe puts a bullet in his skull. His body then gets hijacked by Wildfire.
 * Space Madness
 * Took a Level In Badass: Threeboot, after quitting the Legion.

Supergirl
"AKA: Kara Zor-El (Linda Lee, Linda Lang)

Homeworld: Krypton

Abilities: Super-strength, speed, senses, flight, and invulnerability"

Superman/Superboy I
"AKA: Kal-El (Clark Kent)

Homeworld: Krypton

Abilities: Super-strength, speed, senses, flight, and invulnerability"

Lone Wolf/Timber Wolf/Furball
"AKA: Brin Londo

Homeworld: Zuun

Abilities: Super-human strength and speed, heightened senses, and claws"


 * Animorphism: Mode Locked into the bestial Furball in 5YL.
 * Badass Longcoat: Threeboot.
 * Beast Man / Wolf Man: To varying degrees depending on which part of continuity you look at.
 * Catch Phrase: "Think fast!"
 * Ineffectual Loner: Occasionally averted- in one Postboot story, he takes on the current Fatal Five solo and beats them because they're horrible at teamwork. Generally this holds true, though.
 * Romantic False Lead: Sometimes plays this role for Phantom Girl, against her already-established relationship with Ultra Boy.
 * Super Senses
 * Super Strength
 * Took a Level In Jerkass: His Threeboot counterpart after he received a Power Upgrade. He became stronger and faster, but he also became more aggressive and threatening to his teammates. Slightly Justified by the reveal that Saturn Girl had been exerting a bit of control over his emotions to keep him in check for a while.
 * Jerk With a Heart of Gold: One of his outbursts is caused when he's thanking, in his own way, future teammate Giselle for helping in a battle, and learning that the reason why she wasn't with the rest of the citizens in the safety zone was because the city manager locked her out on purpose. He then attempted to tear said manager's throat out before Saturn Girl intervened. Some of his other outbursts after that could be contributed to his overprotective nature with Princess Projectra.

Triplicate Girl/Duo Damsel/Triad/Una/Duplicate Damsel
"AKA: Luornu Durgo, Marie Elkins

Homeworld: Cargg

Abilities: Able to split into three bodies (as Triplicate Girl/Triad); two bodies (as Duo Damsel); or unlimited bodies (as Duplicate Girl)"


 * Doppelganger Spin
 * Last Of Her Kind: Threeboot Triplicate Girl started out as an amnesiac in the ruins of a world called Cargg, and eventually duplicated enough to repopulate it. She/they sent one of her as an ambassador to the United Planets, who became a Legionnaire... but can't go home again. See Stranger in A Familiar Land, below.
 * Literal Split Personality: Postboot, each duplicate embodies a different personality aspect. Preboot and Retroboot are more Single Minded Triplets (see below). Threeboot is a whole other story originally, but works out similarly to the Single Minded versions.
 * Me's A Crowd: Probably one of the more interesting variations.
 * Single Minded Triplets: Some versions.
 * Stranger in A Familiar Land: Threeboot Triplicate Girl is shunned by her other duplicates back home because of how she's changed from her experiences on Earth.
 * Three Faces of Eve: SW6 and Postboot.

Ultra Boy/Emerald Dragon
"AKA: Jo Nah

Homeworld: Rimbor

Abilities: Able to use one power at a time--ultra-vision, strength, speed, or invulnerability"


 * Boisterous Bruiser
 * Flying Brick: To a degree; the twist is that he can only use one of his powers at a time... but his Legion flight ring takes care of flight for him, so he tends to have a slot open.
 * Jerk With a Heart of Gold / Jerkass Facade
 * Kryptonite Factor: He's harmed by a mysterious "X-radiation", though he almost never encounters it.
 * Obfuscating Stupidity: In the 5YL continuity, Ultra Boy reveals that he plays dumb to throw off his enemies.
 * Perma Stubble
 * Prophetic Name: Got his powers from being swallowed by a Space Whale in some continuities. It's even noticed in-story.
 * Sixth Ranger: In the Postboot, Ultra Boy was originally the leader of Corrupt Corporate Executive Leland McCauley's WorkForce, his answer to the Legion.

White Witch/Jewel/Black Witch
"AKA: Mysa Nal

Homeworld: Naltor (Preboot); Sorcerer's World (Postboot)

Abilities: Sorcery"


 * Anti Hero: Seems to have become this in the Retroboot, due to absorbing Mordru's magic and becoming the Black Witch.
 * Heroic Albino
 * Power Tattoo: Postboot.
 * Vancian Magic
 * White Haired Pretty Girl
 * Wicked Witch: Her Postboot incarnation invoked this trope in her appearance, though she was more amoral than evil. Then she got de-aged into an attractive twenty-something and became a lot more pleasant.
 * Woman in White

Blok
"Homeworld: Dryad

Abilities: Super-strength, durability"


 * Gentle Giant
 * Heel Face Turn: Originally appeared as a member of the Legion of Super-Assassins before going hero after learning he'd been tricked.
 * Last of His Kind
 * Nigh Invulnerable
 * Sacrificial Lamb: His FYL counterpart. His death at the hands of Roxxas was what nudged the Legion into finally reforming.
 * Super Strength

Chameleon Girl
"AKA: Yera Allon

Homeworld: Durla

Abilities: Shapeshifting"


 * Distaff Counterpart: To Chameleon Boy, natch.
 * The Mole/A Wolf in Sheep's Clothing: Impersonated Shrinking Violet when Violet was kidnapped. Yera was not told of their plans and didn't believe she was assisting in any crime. She ended up marrying Colossal Boy while in disguise, although the marriage did not end when she was revealed.
 * Voluntary Shapeshifting

Computo II
"AKA: Danielle Foccart

Homeworld: Earth

Abilities: Controls technology"


 * Canon Foreigner: Sort of. She existed in the original series but only got powers in 5YL.
 * Grand Theft Me: She was possessed by the original Computo as a child (which is how she got her powers).
 * Mission Control
 * Redeeming Replacement: Of Legion villain Computo, the sentient computer who posessed her in an earlier story (giving her powers in the process). She's also the younger sister of the second Invisible Kid.
 * Technopath: She can "speak" to and control computers.

Dawnstar
"Homeworld: Starhaven

Abilities: Flight, long-range tracking"


 * Absolute Cleavage
 * Bi the Way: When the Justice Society tracked Dawnstar's flight ring to Thanagar, they found it in the possession of a woman who implied that she knew Dawny in a rather... intimate way.
 * Braids Beads and Buckskins
 * Magical Native American
 * Scarily Competent Tracker
 * Star Crossed Lovers: With Wildfire.
 * Stuffed Into the Fridge: Her Five Years Later counterpart. There was a supporting character with the same skin tone as Dawnstar who called herself "Bounty", and she was an Anti Hero bounty hunter with a vague backstory. It turned out that she was really Dawnstar, being possessed by a demon called Bounty that amputated her wings. Unlike Lightning Lad and Shrinking Violet, who both had their limbs grown back, Dawny's wings were never restored. And then Zero Hour happened, and that was the last fans saw of her until The Lightning Saga.
 * During Legion of 3 Worlds, artist George Perez drew the wingless Dawnstar deliberately behind where Cosmic Boy's word bubble would be placed.
 * Will They or Won't They: Her relationship with Wildfire.
 * Winged Humanoid

Invisible Kid II
"AKA: Jacques Foccart

Homeworld: Earth

Abilities: Invisibility, formerly also Uncontrolled Teleportation"


 * Humans Are White
 * Invisibility
 * Legacy Character
 * Locked Into Strangeness: He got the white streak in his hair from being touched by Darkseid.
 * My Greatest Failure: He treats the death of Wharlik as this, in spite of not really being responsible.
 * Power Incontinence: Postboot, Jacques was permanently invisible.
 * Skunk Stripe
 * Teleporters and Transporters: Thanks to his DNA being different from Lyle Norg's, he developed this as a secondary power from the serum. However, it was activated by adrenaline and he couldn't control where he ended up, which meant that every time he was startled, or angry, or fighting, he might get sent who-knows-where. Thus, after he accidentally teleported himself and Wharlik, a Khund he was fighting, into space, he had it removed.

Quislet
"AKA: (real name untranslatable)

Homeworld: Teall

Abilities: Object animation"


 * Energy Being
 * Fun Personified: His primary motivation is to seek out exciting new experiences and have fun.
 * Grand Theft Me: Sort of, in that his powers are the possession and animation of inanimate objects.
 * Rogue Drone: He's an escapee from his universe's hive mind.
 * Starfish Aliens: Lacks a body in the traditional sense
 * The Unpronounceable

Tellus
"AKA: Ganglios

Homeworld: Hyrkaius

Abilities: Telepathy and telekinesis"


 * Psychic Powers
 * Mind Over Matter
 * Telepathy
 * Starfish Aliens

Tyroc
"AKA: Troy Stewart

Homeworld: Marzal

Abilities: Sonic manipulation"


 * Absolute Cleavage
 * Angry Black Man
 * Characterization Marches On: Paul Levitz, despite ignoring him in the 1980s, has devoted enough effort in the current Legion volume to move Tyroc beyond his previous "angry black man" personality and make him likable. For the most part, its worked.
 * Collared By Fashion
 * Executive Meddling: How he was created. The writers and artists were all equally disgusted that the editors forced them to include a black character who was both a stereotypical angry black man and a racial separatist, in a time when racism should've been eliminated. Paul Levitz ignored him completely during the 1980s.
 * Green Lantern Ring: His superpowered screams can do basically whatever the writer likes. (Though after a while most writers just treated them as destructive blasts.)
 * Humans Are White
 * Leotard of Power
 * Writer Revolt: No one liked the idea behind this character, especially given that the writers had previously tried to introduce black characters. Mike Grell intentionally made his outfit stupid, comparing it to a cross between Elvis and a football player.

Wildfire/ERG-1/NRG/Wildflame
"AKA: Drake Burroughs

Homeworld: Earth

Abilities: Composed of anti-energy, energy blasts and manipulation"


 * Can't Have Sex Ever: Because he doesn't have a body.
 * Energy Being
 * Fusion Dance: Postboot, Wildfire was created by the fusion of the powers and souls of two dead heroes, Randall "Atom'X" Burroughs and Jahr-Drake "Blast-Off" Ningle.
 * The Heart: Postboot, but not in the main series itself. Two Flash Forward series--Legends of the Dead Earth and DC One Million--show Wildfire as the only surviving member of the original Legion in both the 57th and 854th centuries, respectively, having kept the Legion name alive all that time.
 * Jerk With a Heart of Gold
 * Star Crossed Lovers: With Dawnstar.

Andromeda
"AKA: Laurel Gand

Homeworld: Daxam

Abilities: Super-strength, speed, senses, flight, and invulnerability"


 * The Atoner: After the Daxamite attack on the Postboot United Planets, she joins a convent to atone for her sins.
 * Defector From Decadence: In the Postboot continuity, she was raised in a racist cult, but turned over a new leaf (a while) after she joined the Legion.
 * Defrosting Ice Queen: Before turning over her new leaf, Postboot Andromeda was a hugely racist bitch, only agreeing to join an interspecies, pro-integration organization like the Legion because being a superhero surrounded by "lesser races" still beat being an ordinary teenager going to school back home, where she didn't have any powers.
 * Expy: Of Supergirl, when that character was removed from the Preboot timeline. Her Postboot name was taken from Laurel Kent, Superman's descendant and Legion Academy student from the original continuity.
 * The Mole: In the Postboot, Laurel was secretly a member of the White Triangle, and gave the Daxamite-led group the formula to the serum that protected her from lead.
 * Star Spangled Spandex
 * Statuesque Stunner
 * Superpower Lottery: Before Valor joined the Postboot Legion, Andromeda was the team's most powerful member.
 * Eye Beams
 * Flight
 * Flying Brick
 * Super Breath
 * Super Speed
 * Super Strength
 * Weaksauce Weakness: Like all Daxamites she has a fatal allergy to even trace amounts of lead. In all continuities where she exists, Brainiac 5 developed a serum which soon rid her of the problem, but early on in the Postboot she had to wear a transuit at all times to avoid exposure (and actual physical contact with the "lesser races").

Catspaw
"AKA: April Dumaka

Homeworld: Earth

Abilities: Super-human strength and speed, enhanced senses, and claws"


 * Beastess
 * Catgirl
 * Expy: Catspaw was the Legionnaires' rough equivalent to Timber Wolf (who also existed in their continuity, but was not one of the Batch SW6 duplicates).
 * Super Senses
 * Touched By Vorlons: She got her powers from gene-altering experiments performed on her by the Dominators.

Dragonmage
"AKA: Xao Jin

Homeworld: New Shanghai Colony

Abilities: Sorcery"


 * Ambition Is Evil: His desire to get his powers back Postboot led him to inadvertently release the Elements of Disaster, who almost destroyed the United Planets.
 * Canon Immigrant: He first appeared in 5YL as a new member to join the SW6 Legionnaires; he later reappeared in Postboot, albeit not as a Legionnaire. He briefly turns up as one of Mordru's undead warriors (in the Preboot universe) in Legion of Three Worlds.
 * De Power: By Mordru Postboot.
 * Ethnic Magician: He's very stereotypically Chinese, at least in appearance and powers.
 * Squishy Wizard

Kid Quantum I
"AKA: James Cullen

Homeworld: Antares (Preboot); Xanthu (Postboot)

Abilities: Temporal manipulation; shapeshifting, telepathy (Preboot only)"


 * Back From the Dead: Preboot, very shortly before Zero Hour.
 * Humans Are White
 * Posthumous Character: Kid Quantum was originally created as one of these, who died tragically to justify the Legion's rule against members using devices for their primary powers.
 * Ret Here: In V4, he was a side effect of a small-scale Cosmic Retcon.
 * Sacrificial Lamb: Postboot actually showed his induction into and first mission with the Legion--during which, of course, he died, becoming Leviathan's Greatest Failure in the process.
 * Time Stands Still: He augmented his ability with a "stasis belt", which failed at the worst possible time.

Gates
"AKA: Ti'julk Mr'asz

Homeworld: Vyrga

Abilities: Teleportation"


 * Bee People
 * The Call Knows Where You Live: Unlike almost every other Legionnaire, he was not a volunteer. His planet drafted him so they'd have a representative on the team.
 * Canon Immigrant: Postboot is the only Legion continuity with a Gates. In Legion of Three Worlds, he notices and calls speciesism on the parallel universes. He joins the Retroboot Legion to even things out a bit.
 * Dropped a Bridge On Him: Cynically killed off in the first issue of Legion Lost v2, 2011).
 * Ensemble Darkhorse: Probably because he was so different from a typical Legionnaire.
 * Mass Teleportation
 * My Species Doth Protest Too Much
 * Only Known By Their Nickname
 * Portal Cut: loses most of an arm being cut off by the edge of one of Gates's portals being used to rescue someone from the villain's grasp, taking the arm with him. This is the first indication that the portals which he's been using for years have sharp edges, which is kind of Nightmare Fuel when you consider that he can create and move them about at will...
 * Soapbox Sadie: Most of his dialogue consists of complaining about the "capitalist police state" he's been drafted into.
 * Strawman Political: He's a revolutionary communist- this doesn't stop him being an interesting and well-developed character, though.
 * Teleporters and Transporters
 * We Are As Mayflies: Inverted. Gates's species has a much shorter lifespan than humans, with 20 being elderly.

Gear
"AKA: I.Z.O.R.

Homeworld: Linsnar

Abilities: Grows organic technology from his body"


 * Defector From Decadence: Gear's species see themselves as nothing but tools for other people to use. Gear (with a little help from Sensor) said "Screw that!" and set out to make his own destiny.
 * Do Anything Robot
 * Hollywood Cyborg: His entire species are bio-mechanical machines.
 * Humans Are White
 * Mr. Fixit
 * Non Action Guy: Constantly reiterated that he was a noncombatant.
 * Ray Gun: Among Gear's bio-equipment are a number of laser blasters.

Kid Quantum II
"AKA: Jazmin Cullen

Homeworld: Xanthu

Abilities: Temporal manipulation, throws damaging "q-spheres""


 * Humans Are White
 * Legacy Character
 * Sassy Black Woman
 * Time Stands Still: Without the belt, this time.

Kinetix
"AKA: Zoe Saugin

Homeworld: Aleph

Abilities: Manipulates inanimate objects"


 * Ambition Is Evil: Ultimately averted, but her well-intentioned obsession with gaining powers wasn't portrayed as healthy.
 * Baleful Polymorph: Happened to her more than once.
 * Brought Down to Normal: She lost her powers early on, prompting her to go on a search for new ones or a way to restore them.
 * Catgirl: Postboot crone!Mysa turns her into one for a while.
 * Les Yay: With Shrinking Violet.
 * Power Tattoo: Briefly.
 * Red Herring Mole: She was constantly portrayed as a potential Emerald Empress-in-the-making, until The Reveal of who had the Eye.

Magno
"AKA: Dyrk Magz

Homeworld: Braal

Abilities: Magnetism manipulation"


 * C-List Fodder
 * Demoted to Extra
 * De Power: Dyrk loses his powers in the fight against Mordru, and ends up as part of the Legion's support staff when the team won't give up on him.
 * Expy: Of Preboot Pol "Magnetic Kid" Krinn, arguably. Pol, Cosmic Boy's little brother, also appears in Postboot, but never joins the Legion; instead, Magno is the one who struggles with being overshadowed by Cos.
 * Extra Ore Dinary
 * Mission Control
 * Replacement Scrappy: In-universe, several characters - most notably Live Wire - treated him this way after he joined the Legion in Cosmic Boy's absence. Some fans see him this way as well, even though his character was never actually presented as a replacement for Cos, who was still a series regular (just stranded in the past).
 * Ship Tease: While XS is depicted as crushing on a number of different guys, Dyrk was the first one to show interest in her... which she didn't notice until after she'd accidentally brushed him off. And then the timeline ended.
 * What Happened to The Mouse: In Legion Worlds #3, Cosmic Boy promises to let Dyrk, now a Sci-Cop, in on what the Legion is up to (the construction of Legion World and their return to active duty) as soon as he has a chance. The Legion ran for a year or two after that, but even when Cosmic Boy is shown returning the planet where Dyrk is still presumably serving as a police officer, Dyrk is never mentioned again and has yet to appear in any subsequent versions, not even L3W.

Monstress
"AKA: Candi Pyponte-Le Parc III

Homeworld: Xanthu

Abilities: Super-strength"


 * Apron Matron: A young version, as she's always calling her teammates "dear" and watching out for their emotional well being without being overbearing.
 * Beware the Nice Ones: Even Candi has her limits.
 * Big Beautiful Woman
 * Brawn Hilda
 * Dropped a Bridge On Him
 * Expy: Postboot's rough equivalent to Blok.
 * I Am Big Boned: Never stated outright, but her size is due to her mutated bone structure.
 * Odd Friendship: With Postboot Element Lad. Which makes her death all the more sadder.
 * Spoiled Sweet
 * Super Strength

Shikari Lonestar
"Homeworld: Kwai migrating colony

Abilities: Flight, transdimensional navigation, bio-armor"


 * Bee People
 * Expy: Of Dawnstar, who was deemed too silly for Postboot.
 * Meaningful Name: "Shikari" is a term used in India for a hunter and guide.
 * My Species Doth Protest Too Much: Sort of. In the peaceful, community-minded culture of her species, Shikari's wanderlust and more warlike tendencies make her something of a throwback.
 * The Nicknamer: Of sorts; some quirk of culture or language leads her to call her teammates names along the pattern of "X Legion" - Brainiac 5 became "Smart Legion" or "Green Legion," Umbra is "Dark Legion," etc. Possible explanation is that she is from a such different part of the universe that even the translated interlac sounds too weird to her.
 * Canon Immigrant: In the Legion annual that wiped Postboot from continuity and established Threeboot, Shikari was accidentally trapped in the Threeboot world. This clearly earth-shaking development was never followed up on, and she simply reappeared with the Postboot Legion in Legion of Three Worlds saying "Oh, there you guys are."
 * Scarily Competent Tracker: This is a racial ability, which eventually leads to Kwai navigators being implemented as a means of using "thresholds" for personal interplanetary teleportation throughout the United Planets, because the Kwai can navigate in the other-space that threshold technology moves mass through.

Superboy II
"AKA: Kon-El (Conner Kent)

Homeworld: Earth

Abilities: Super-strength, speed, senses, flight, invulnerability, and tactile telekinesis"


 * Fish Out of Temporal Water: He was stuck in the Legion's time period for a while, but simultaneously appeared in Teen Titans... eventually, Teen Titans had a crossover with the Legion in which he disappeared from the 21st century, then came back moments later, having traveled to the point in the Legion's timeframe where he first appeared, then spent several months there before being sent back to get the Titans and bring them to the future for a time-traveling team-up.

Thunder
"AKA: Cece Beck

Homeworld: Binderaan

Abilities: Super-strength, speed, flight, invulnerability"


 * Fish Out of Temporal Water: She's from the 90th century, 6000 years after the Legion's time.
 * Flight
 * Flying Brick
 * Legacy Character: Of Captain Marvel.
 * Older Alter Ego: Like Captain Marvel. She's around 10 or 12, but her super-powered form appears around 16.
 * Put On a Bus / Brother Chuck: It was established early on that only Thunder had been sent to the Legion's time period; when she changed back to Cece, she appeared in her home time, and when she transformed again, Thunder was back with the Legion. After "Legion of the Damned", which destroyed the stargate system and made interplanetary travel take months or years again, the Legionnaires are devastated by the sudden distance separating them from friends and family, and Thunder, realizing she's lucky enough to be able to visit her parents without a ship, says the magic word and returns home. She says she'll be back, but the timeline ends before she's seen again.
 * Shout Out: Her name and home planet are in-jokes on Captain Marvel creators C.C. Beck and Otto Binder.
 * Super Strength
 * Super Speed

XS
"AKA: Jenni Ognats

Homeworld: Aarok

Abilities: Super-speed"


 * Canon Immigrant: First appeared in the Postboot Legion; Legion of Three Worlds retconned her as being a refugee from the Retroboot Legion's world and had her join them.
 * Cowardly Lion: Originally, but in literally her second appearance she gets over it in time to save the entire Legion from
 * Fragile Speedster: Notably, unlike most speedsters, she's never shown vibrating through solid objects (destructively or otherwise)- probably because this would make Apparition obsolete.
 * Genki Girl
 * Humans Are White
 * Legacy Character: The granddaughter of Barry Allen.
 * Motor Mouth
 * Strapped to An Operating Table: Her origin story has her growing up without superspeed, despite being the granddaughter of the Flash and the daughter of one of the Tornado Twins- until, in an attempt to understand and duplicate her bloodline's powers, the Dominators abducted her, and the trauma of their experimentation triggered the emergence of her powers.
 * Super Speed

Dream Boy
"AKA: Rol Purtha

Homeworld: Naltor

Abilities: Precognition"


 * Cassandra Truth: Nobody listens to him because they're bitter about his status as (more or less) an affirmative action hire. The fact that he's a precog like the original Cassandra makes this even more appropriate.
 * Chuck Cunningham Syndrome: He disappeared after the Dominator War.
 * Dreaming of Things to Come
 * Suspiciously Similar Substitute: In-story, a replacement for Dream Girl sent by their planet's government.
 * White Haired Pretty Boy

Gazelle
"AKA: Giselle Smith

Homeworld: Triton

Abilities: Conscious metabolic control"


 * Facial Markings
 * Hot Amazon: Invisible Kid develops a crush on her after seeing her in action.
 * Misunderstood Loner With a Heart of Gold: She's considered a freak by her own society because of her powers and appearance, and even her parents seem to slightly think she's a lost cause. She also got off to a rocky start with the Legion, considering them "sell-outs", but she does help a squad of Legionnaires by telling a group of Science Policemen they went the other way.
 * Super Speed and Super Strength: In limited bursts.
 * Weaksauce Weakness: She can only "run hot" for a few minutes, after which she becomes extremely fatigued until her protein levels get back up. She keeps supplies of glycogen on hand to stave this off.
 * What Kind of Lame Power Is Heart Anyway: In addition to "running hot", she can also slow down her metabolism and play dead. She admits that this is a very limited power.

Sizzle
"AKA: Teela Spuunvll

Homeworld: Abaddonus

Abilities: Absorbs, alters, and redirects energy"


 * Glass Cannon
 * Weaksauce Weakness: She needs a steady power source to fuel her energy projection powers. This also makes her fairly redundant.

Theena
"Homeworld: Unknown

Abilities: Bonded to clairvoyant symbiont"


 * Chuck Cunningham Syndrome: Following Mark Waid's departure, Theena appeared for only one panel the next issue and then completely disappeared from the series.
 * Mauve Shirt: She's one of the hordes of teens camped outside Legion headquarters.
 * My Significance Sense Is Tingling: The strange "screens" on her psychic symbiont's appendages allow for remote viewing of almost any location in the universe. She usually uses them to help the Legion's allies keep tabs on them.

Turtle
"AKA: Bogdan Tarka

Homeworld: Doopa

Abilities: Invulnerability"


 * Nigh Invulnerable: His only power is that he's ridiculously hard to harm (though it is possible). This was deemed cool, but his lack of offensive capabilities sent him to the Legion Reserve.
 * Petting Zoo People: Doopans are all very turtle-like, but evidently Turtle is especially durable.
 * Stone Wall

In addition to the Legion, myriad other characters, heroes and villains alike, live in the 31st century.

Dev-Em
"AKA: Dev-Em (Preboot); David Emery (Softboot)

Homeworld: Krypton (Preboot); Titan or Daxam (Softboot)

Abilities: Super-strength, speed, senses, flight, and invulnerability"


 * Continuity Snarl. He was originally one of the many Kryptonians of the Silver Age and was Put On a Bus by having him stay in the Legion's future. This made him available to be brought back during the 1980's Legion series. Okay so far, until Superman's history was changed in 1986 to make Superman the sole surviving Kryptonian. This caused problems. He was variously retconned into a Titanian whose powers turned him into a Kryptonian (which was mentioned only in supplementary material), a good Daxamite, and an evil Daxamite. Now that there are other Kryptonians again, two characters with that name have been introduced, one Kryptonian criminal, and one cultist in 52; neither one fits with the Legion version.
 * Heel Face Turn
 * Superpower Lottery
 * Eye Beams
 * Flight
 * Flying Brick
 * Super Breath
 * Super Speed
 * Super Strength

Inferno II
"AKA: Sandy Anderson

Homeworld: Earth

Abilities: Pyrokinesis, flight"


 * Anti Hero
 * Broken Bird
 * Canon Immigrant: Sort of. First appeared in the reboot era, and came to the present as part of a story where several Legionnaires were stuck in the present day. When they returned to the future, she stayed in the present. Since she was not Put On a Bus with the rest of the reboot, she could in theory show up at any time. A green-skinned version also appeared in the Threeboot.
 * Flight
 * Green Skinned Space Babe: in the Threeboot.
 * Playing With Fire

The Legion of Substitute Heroes

 * Mundane Utility: After bombing as superheroes, Color Kid and Fire Lad went into business as very successful glassblowers.
 * Nakama: Perhaps moreso than the "real" Legion, the Subs see each other as family first.
 * Super Zeroes
 * What Kind of Lame Power Is Heart Anyway

Antennae Lad
"AKA: Khfeurb Chee Bez

Homeworld: Gryxor

Abilities: Can hear radio transmissions"


 * What Kind of Lame Power Is Heart Anyway: He can hear radio transmissions... all of them. Not necessarily from this universe or time period, mind you, but he can hear them.

Chlorophyll Kid/"Plant Lad"
"AKA: Ral Benem

Homeworld: Mardru

Abilities: Manipulates plant growth; claims he can talk to them, which he cannot"


 * Green Thumb: Essentially taken to its logical conclusion - he can accelerate the growth of plants, and that's his only power. The inability to actually control plants is the largest reason for him never being accepted
 * Heroic Build: Originally played straight when he was first introduced in the Silver Age, up until the 1980s when the Subs were rewrote as a group of incompetent fanboys, and he was made rather obese. Following the return of the "original" Legion, he was slimmed back down.

Color Kid (Color King)
"AKA: Ulu Vakk

Homeworld: Lupra

Abilities: Can change color of any object"


 * Ambiguously Gay: In some continuities, most notably the cartoon.
 * Heart Is an Awesome Power: When it can turn Green Kryptonite into harmless Blue Kryptonite, when you can use it to turn the air black (remember, Night Girl is his teammate), and when you need an effective disguise or you want to disorient your foes.
 * What Kind of Lame Power Is Heart Anyway: The page picture, even!

Double Header
"AKA: Frenk and Dyvud Retzun

Homeworld: Janus

Abilities: Has two heads. (Really.)"


 * Mes a Crowd: Kinda. Eventually, he'll split into two whole people.
 * Multiple Head Case
 * Sibling Yin Yang: Sort of. The heads are technically brothers, and they hate each other.
 * What Kind of Lame Power Is Heart Anyway: Even among the Substitute Heroes, having two heads that never cooperate is an incredibly pathetic "power".

Fire Lad
"AKA: Stag Mavlen

Homeworld: Schwar

Abilities: Breathes fire with moderate control at best"


 * Unskilled but Strong: The reason his membership has been repeatedly denied. His fire breath is incredibly potent, but he lacks the ability to control it in any meaningful way. The original incarnation even had terrible allergies that would often activate his powers. Preboot, he would eventually achieve a level of control that was frankly ridiculous, capable of making ice sculptures with his fire breath, but this would be ignored in Retroboot.

Infectious Lass
"AKA: Drura Sepht

Homeworld: Somahtur

Abilities: Spontaneous generation of infectious diseases"

"Infectious Lass: Hi, fellas. You're now officially walking hot zones.
 * Ascended Fangirl
 * Plaguemaster: A rare heroic example.
 * Put On a Bus: In Retroboot, she was banished to Limbo by Earth-Man (where she joined up with Doctor Thirteen and a Nazi gorilla).
 * Unskilled but Strong: Like many of her teamates, her inability to control her powers is her downfall. In her second attempt to apply for Legion membership, she boasts that she's much more powerful than before and can even cause epidemics... but her control hasn't improved remotely.
 * What Kind of Lame Power Is Heart Anyway: She makes people sick. Like, aches and sniffles (or more exotic diseases).
 * Heart Is an Awesome Power: In the last postboot story, Drura is introduced as a Legion cadet, airlifted in as part of emergency backup during a riot in Metropolis, and demonstrating much greater control of powers than the previous version, reduces two dedicated terrorists to vomiting bags of sick who eagerly give up the location of their ringleader.

...

Arrow: I'm... I'm willing to die for my cause.

Chameleon: Oh, you'll die. We'll all die someday. The issue is, do you want to die in your bed surrounded by loved ones... or bent over in this alley with a woefully inadequate supply of tissues?"

Porcupine Pete
"AKA: Peter Dursin

Homeworld: Earth

Abilities: Shoots quills from his body"


 * Flechette Storm
 * Unskilled but Strong: His quills are extremely harmful.. to friend and foe alike, since he can only shoot them all at once and in all directions surrounding him.

Rainbow Girl
"AKA: Dori Aandraison

Homeworld: Xolnar

Abilities: Wields the powers of the mysterious emotional spectrum, resulting in unpredictable mood swings"


 * Mood Swinger: She doesn't have full control over her power to tap into the emotional spectrum, which leads to her going from raging mad to hopeful to cocky and willful in the space of a few panels.

Stone Boy
"AKA: Dag Wentim

Homeworld: Zwen

Abilities: Able to transform his body to stone, but forced to remain inanimate"


 * Heart Is an Awesome Power: He even won a contest held by the Legion proper with membership as the prize, which he rejected because he couldn't bear to abandon his friends.
 * The Stoic: Often characterized as being an extremely taciturn and serious individual
 * Stone Wall: Essentially invulnerable in stone form, but incapable of movement.
 * Taken for Granite: What his power amounts to, turning into an immobile statue. Eventually, Preboot Stone Boy learned how to turn just his fists to stone, but this is usually ignored by other incarnations.

Computo I/Mister Venge
"Homeworld: Earth; later Robotica (Postboot)

The Dominators

 * The Baroness: Though which version she's closer to tends to vary from comic to comic.

 * The Dark Chick: In the comics, although she and Mano sometimes swap these roles.
 * Faceless Eye: As her main weapon.
 * Legacy Character: Several women have posessed the Eye -- or been turned to the dark side by it when they caught its fancy.
 * You Gotta Have Green Hair

Mano

 * Cool Helmet: As part of his spacesuit.
 * The Dark Chick: More so than the Empress even (who's often The Big Bad). He's definitely wierd, and has been known to clash with the other members, especially in later versions of the story. Played up in the cartoon; in the comics he might be closer to The Evil Genius.
 * The Faceless: His entire species resemble shadows, and as such, have no faces.
 * Mutant
 * Omnicidal Maniac: Deliberately blew up his home planet of Angtu in the original series.
 * Person of Mass Destruction: When he wants to be.
 * Poisonous Person: His touch causes the bonds between atoms to break down, resulting in disintegration.
 * Red Right Hand: Yellow actually. It really stands out on his shadowy black body.
 * Well Intentioned Extremist: Postboot only.

The Persuader

 * An Axe to Grind: His Atomic Axe can cut through anything--including space/time.
 * Bald of Evil
 * The Dragon: To Tharok in the comics and the Empress in the cartoon.
 * Empathic Weapon: Sometimes used to justify his axe's abilities.
 * Heavyworlder
 * Super Strength

Tharok

 * Big Bad: In the comics.
 * Crazy Prepared: He has tiny missiles inside his ears just in case someone with shrinking powers tries to mess with his brain.
 * Evil Genius: The smartest, most competent member of the team. In the TV show he also fullfills this role in the Five Bad Band, as the Empress is the Big Bad.
 * Hollywood Cyborg
 * Super Strength
 * Two Faced: His left side is completely robotic, while his right side is flesh.
 * We Can Rebuild Him: He was once a common thief, but his left side was vaporized when he was apprehended. The authorities rebuilt him, turning him into a hyper-intelligent cyborg in the process. Nice one!

Validus

 * The Berserker: Sometimes slips into Unstoppable Rage mode. It's the reason he's to be executed in the original comics, despite not being an actual villain: he's simply too dangerous to leave alive.
 * The Brute
 * Dumb Muscle
 * Psychic Powers: He can generate intense blasts of "mental lightning" that stun his foes.
 * Retroactive Legacy: Tribulus from R.E.B.E.L.S. is a clear precursor to whatever technology created him.
 * Tragic Monster: Whoo boy.
 * Unstoppable Rage

Mordecai

 * The Brute: But not Dumb Muscle, as he was actually a fairly sensitive poet.
 * Canon Foreigner: Mordecai appears only briefly in Glorithverse.
 * Suspiciously Similar Substitute: Of Validus, who was off-limits at the time due to messed-up continuity issues.

Glorith

 * Ascended Extra: was a one-shot minor villain in the 1960's until brought back for Five Years Later.
 * Big Bad: Of the Glorithverse, naturally.
 * The Chessmaster
 * I Am Not Shazam: Many people operate under the belief that Glorith was another of the Time Trapper's identities. The truth is, that she merely replaced him as the Legion's time manipulating Big Bad. All his accomplishments became her's, and she remembered everything from the previous timelines. She even met the Trapper in the remains of his pocket universe and tried to stomp out his remaining consciousness while gloating how everything he created was now her's, only, as she put it, "better".

Grimbor the Chainsman

 * Badass Normal

The Justice League of Earth

 * Putting On the Reich
 * Token Evil Teammate: The Legion was forced to take Niedrigh on as a member by Earthgov due to his popularity among anti-alien humans.
 * Villain With Good Publicity

Eyeful Ethel

 * Even Evil Has Loved Ones: She and Tusker really do love each other.
 * Evil Blonde: She originally had black hair.
 * Hollywood Homely: In her first appearance, she was very pretty (with the exception of the multiple eyes around her head). After she got older she become rather dumpy, and her extra eyes were now permanently on her forehead. Following the reboot, she lost weight and dyed her hair.
 * Sadist Teacher: Revels in the fact that her students will believe anything she tells them because she's their teacher.
 * What Kind of Lame Power Is Heart Anyway: Her power is that she can sprout eyeballs on any part of her body. Not terribly useful in combat.

Golden Boy

 * Chrome Champion

Radiation Roy

 * Blessed With Suck: His atomic powers permanently disfigured him.
 * I Love Nuclear Power
 * Energy Beams

Storm Boy

 * Heel Face Turn: His Five Year Later counterpart actually got over his rejection and went on to work with weather-generating machinery, before joining the Legion when they were desperate for members during the Five Year Gap.
 * I Just Want to Be Special: So he replaced most of his internal organs with weather-control machines.
 * Motive Decay: His original reason for joining the Legion was a stunt for a fraternity. In the Reboot continuity he claims that he very badly wanted to join the Legion and considers them amoral bullies for not understanding what that kind of rejection does to someone.

Tusker

 * The Brute
 * Even Evil Has Loved Ones: He's in a relationship with Eyeful Ethel.
 * Nigh Invulnerability: Specifically, his skeleton is indestructible. His skin is pretty durable, too.
 * Pet the Dog: Saved Ethel from being hit by the Subs' high-jacked school bus.
 * Took a Level In Badass: His powers evolved from a set of expandable tusks to an unbreakable skeleton.

The Khunds

 * The Empire

 * Proud Warrior Race Guy: The Khunds are not unlike The DCU's answer to Klingons.
 * Space Pirates

The Legion of Super-Villains

 * Aristocrats Are Evil: Not actual aristocrats, but check out the names on most of them, especially the original three.
 * Legion of Doom: Evolve into this.
 * Psycho Rangers: How they started out, with Lightning Lord, Saturn Queen, and Cosmic King balancing out Lightning Lad, Saturn Girl, and Cosmic Boy. Some later members, like Sun Emperor have conformed with this, others, like Nemesis Kid, have not.
 * Terrible Trio: Originally made up of Cosmic King, Lightning Lord, and Saturn Queen.

Cosmic King
"AKA: Laevar Bolto

Homeworld: Venus

Abilities: Transmutation of chemical elements"


 * All of the Other Reindeer: After accidentally gaining his powers, he was exiled from his home planet of Venus, where transmutation is regarded as inherently evil.
 * And Man Grew Proud: How the other Venusians view his creation of the transmutation ray.
 * Big Bad: In the Silver Age at least, where he was not only a founding member of the Legion, but the leader of the initial Terrible Trio.
 * Beard of Evil: In later versions. The original was clean shaven.
 * Cool Helmet: Sometimes pictured in a space suit and helmet.
 * Demoted to Extra: He's one of the founding members of the Legion of Super Villains, but he doesn't get nearly the screen time of Saturn Queen, Lightning Lord, or even Sixth Rangers like Nemesis Kid.
 * Evil Counterpart: To Cosmic Boy, though their powers are vastly different. In fact, his powers make him more like Element Lad or Chemical King. As the leader of the original Terrible Trio however, he is very much the Evil Counterpart to Cos.
 * The Exile: Kicked off of Venus for practising transmutation.
 * Mad Scientist: Pre-supervillany
 * Revenge: In classic Super Villain fashion, he sees his actions as a way of getting back at the Venusians who banished him.
 * Start of Darkness: Tried to create a transmutation ray to solve his planet's environmental problems. Was shunned and exiled for it. Way to go people.

Lightning Lord
"AKA: Mekt Ranzz

Homeworld: Winath

Abilities: Electrical generation and direction"


 * Arch Enemy: To his brother.
 * Artistic Age/ Younger Than They Look: He looked about sixty in his original appearances. Later versions have been better about this, but the combination of his ravaged face and white hair still make him look a lot older than his younger brother.
 * Badass Moustache: In the original comics.
 * Cain and Abel: With Lightning Lad and Light Lass.
 * Corrupt the Cutie: Preboot he would repeatedly try to get Light Lass to come over to his side.
 * Death Seeker: Threeboot.
 * Evil Counterpart: To Lightning Lad/Live Wire.
 * Evil Redhead: When he's not a White Haired Pretty Boy or an old man.
 * Freudian Excuse: If you think being a solo counts.
 * Heel Face Turn: In most continuities, Mekt turned into a good guy, or at least less of a bad guy.
 * Loners Are Freaks: His mental instability is usually attributed to being born a "solo" on a world where twins are the norm.
 * Pet the Dog: The Preboot version has a genuine soft spot for his sister, who he wishes would join him in his life of crime.
 * Psycho Electro: Though how psycho he is varies from version to version.
 * Shock and Awe
 * White Haired Pretty Boy: When he's the same age as the others.
 * With Great Power Comes Great Insanity: Invoked in-universe during the Reboot. Live Wire believed that the lightning abilities which the three of them gained would wind up corrupting them, which is why Mekt became a criminal. When Garth finally confronted his brother with this theory, Mekt rebuffed it, and Ayla finally managed to convince Garth that Mekt was always rotten... after Mekt had destroyed Garth's right arm.

Saturn Queen
"AKA: Eve Aries

Homeworld: Titan

Abilities: Telepathy"


 * Card Carrying Villain: In the original comics, there was no crime on Saturn due to certain minerals in the rings (hey, it was the Silver Age). Upon coming to Earth, and getting out of range of the rings, she just decided, "hey I think I'll turn evil for the Hell of it."
 * Evil Counterpart: To Saturn Girl.
 * Evil Matriarch: In "Absolute Power" and the Kandor arc of the new Supergirl series. She seems to have developed an obsession with having a child to serve as her Dragon. In both cases, she's gotten to watch said child die.
 * Evil Redhead
 * For the Evulz: Why she originally became a villain.
 * Mind Rape: Inflicts it on her victims, including Superman.
 * Heel Face Turn: In the original comics, prompted by Superman exposing her to Saturnian elements. More recent versions, not so much.
 * Her Five Years Later counterpart turned and stayed good, eventually marrying Matter-Eater Lad and becoming queen of Titan.
 * Humans Are Bastards: More like all living beings are bastards. This has become her belief in the most recent reboot.
 * Misanthrope Supreme: Which she uses to justify her For the Evulz tendencies.
 * Telepathy

Sun Emperor
"AKA: Nigal Douglous

Homeworld: Earth

Abilities: Solar energy generation and manipulation"


 * Ax Crazy
 * Evil Counterpart: To Sun Boy
 * For the Evulz: He once murdered a waitress for no apparent reason other than he felt like it, freaking out his teammates, who are known as vicious psychopaths.
 * Playing With Fire
 * Pyromaniac

Superboy-Prime
"AKA: Kal-El (Clark Kent)

Homeworld: Krypton-Prime

Abilities: Super-strength, speed, senses, flight, and invulnerability"

Chameleon Chief
"AKA: Jall Tannuz (?)

Homeworld: Not Durla, strangely enough.

Abilities: Shapeshifting, can also change objects"


 * I Am Not Weasel: Looks like a Durlan, has the same powers as a Durlan, but apparently not actually Durlan.

Nemesis Kid
"AKA: Hart Druiter

Homeworld: Myar

Abilities: Spontaneously develops powers to defeat a single opponent"


 * Blond Guys Are Evil
 * Green Lantern Ring: His power can literally do anything if it could help him defeat his opponent. In the cartoon, his power was simplified so that he could just De Power superhumans.
 * No Holds Barred Beatdown: Delivers one of these to, basically killing him with his bare hands.
 * Oh Crap:
 * The Mole / Sixth Ranger Traitor: He joined the Legion to spy on them for the Khunds. Later, he became a member of the Legion of Super-Villains.

 * Corrupt Corporate Executive
 * Evil Counterpart: To R. J. Brande.
 * Evil Mentor: To the WorkForce.
 * Fiction 500: He's the second-richest man in the galaxy, after R. J. Brande. McCauley hates Brande for this reason.
 * President Evil: Postboot, in the DnA era. It was actually Ra's al-Ghul, who killed McCauley and used his fortune to run for president.
 * Screw the Rules I Have Money: He typically buys his way out of his problems.
 * Smug Snake
 * Verbal Tic: 5YL McCauley liberally peppers his dialog with nervous laughter.

Mordru the Merciless
"Homeworld: Sorcerers' World

Abilities: Sorcery, immortality"


 * Bigger Bad: Postboot. Mordru was unquestionably the most powerful foe the Legion went up against, but lesser threats like C.O.M.P.U.T.O. and Ra's al-Ghul hit closer to home.
 * Dimension Lord: In some continuities, Mordru's domain, Sorcerer's World, is a dimension unto itself. (In others, it's merely a planet in the material universe.)
 * Evil Sorcerer
 * Galactic Conqueror: Mordru ruled a star-spanning empire before his initial defeat.
 * Humanoid Abomination: Post Crisis, Mordru was revealed to be one of the immortal Lords of Chaos rather than a human wizard.
 * Kryptonite Factor: Mordru suffers from a crippling phobia of being buried alive. A Shout Out to its origin appears many years later: "We all make our own weaknesses, his from a nightmare happenstance long in his past."
 * Sealed Evil in A Can: His original era and post boot incarnations both started as this.
 * Wizard Beard
 * Wizards Live Longer

Praetor Lemnos
"Abilities: Memory modification"


 * Big Bad
 * The Chessmaster
 * Cursed With Awesome / Blessed With Suck : His powers allow him to get away with anything, but at the same time he can't form any lasting relationships, or be remembered for doing anything good.
 * Evil Genius
 * Facial Markings
 * Fiction500: Those who can remember his name know he's one of the richest and most influential men in the galaxy. Not that there's many who do.
 * Freudian Excuse: Built in. He had to stay in his parents' line of sight, so they'd remember to feed him. And then there was that bit where the government tried to capture him to learn how his powers worked.
 * Invisible to Normals: He has the unique ability to alter information with his mind--including recorded data and people's memories--making him effectively invisible.
 * Karma Houdini: His power. "You'd be amazed what a smart man can get away with in this world, if he never has to take responsibility for his actions." They do get him in the end though.
 * The Man Behind the Man: And not always by choice.
 * Parental Abandonment: Not that it was intentional.
 * Shadow Archetype: To the Legion as a whole. They both want to shake the 31st century out of its malaise, but whereas the Legion wants to do it peacefully, Lemnos wants to do it with a war.
 * Well Intentioned Extremist

Sklarian Raiders

 * Amazon Brigade
 * One Gender Race
 * Pirate Girl
 * Space Pirates

The Time Trapper
"AKA: Identity changes frequently

Homeworld: Unknown/multiple

Abilities: Temporal manipulation; others depending on identity"


 * After the End: He/She/It lives at the end of time, or not. Depending on the continuity
 * Purple Cloak
 * The Chessmaster
 * Bigger Bad: The Trapper is arguably the most powerful, resourceful, and persistent foe the Legion has faced.
 * Deflector Shield: His/Her/It's iron curtain of time.
 * In the Hood: Trapper's identity is either Superboy-Prime, Cosmic Boy, Lori Morning, Weeja Dell, A sentient Time-Line, A living embodiment of Entropy, or some dick with Cosmic Powers.
 * Multiple Choice Past: Probably the only character for whom this is an actual power--he has the ability to change his own past, down to his very identity. The Time Trapper has been, among others, Cosmic Boy, Lori Morning, and Superboy-Prime.
 * Or S/He could be all of those people, only from different futures.
 * Physical God: At least while he was Superboy-Prime.
 * Time Abyss: An odd case. The Trapper's history begins a thousand years in our future, but ends untold billions of years after that.
 * But with the constant change in Identity and continuity., He/She could be from the modern time or from the beggining of time or even next week.
 * Time Master: In the truest sense.

Universo

 * Everythings Better With Monkeys
 * Fish Out of Temporal Water
 * Pokémon Speak: "KOKO!"
 * Shoo Out the Clowns: At the end of the more lighthearted Peyer/McGraw/Stern era, in the issue before the Darker and Edgier DnA era began, Koko leaves the series to settle down with a female space monkey on a remote jungle planet.
 * Team Pet

Lori Morning

 * Fish Out of Temporal Water
 * I Just Want to Be Special
 * Legacy Character: She gets a hold of the Hero Dial from Dial H for Hero for a while.
 * Word of God eventually supported Epileptic Trees from the time that she was meant to be the Postboot Glorith. (At one point the Time Trapper calls her "glorious"; glorious + Lori = Glorith.)
 * Plot Relevant Age Up
 * Tagalong Kid

Marla Latham

 * Ambiguously Gay: Insofar as he's impeccably groomed and enjoys hanging out with Brande at mud baths.
 * Reasonable Authority Figure

M'rissey

 * Improbable Age: He's a 13-year-old economic/diplomacy genius.

 * Voluntary Shapeshifting

R. J. Brande

 * Catch Phrase: "By damn!"
 * Fan of the Past: He has a sizeable collection of 20th- and 21st-century memorabilia. Not surprisingly, since he's either implied to be or explicitly from the Present Day, depending on the continuity.
 * Fiction 500: He's the richest man in the galaxy.
 * Luke I Am Your Father: A Preboot miniseries revealed that Brande was a mode locked Durlan, and Chameleon Boy's father.
 * Mentor
 * Reasonable Authority Figure
 * What Could Have Been: It was blatantly obvious that Postboot was building up to The Reveal that Brande was actually the Martian Manhunter, drastically weakened and Mode Locked into human form, but the continuity was rebooted before the reveal ever took place.

Gigi Cusimano

 * Tuckerization, of Paul Levitz's wife

Shvaugn Erin/Sean Erin

 * The Commissioner Gordon: Frequently a liason between the Legion and the Science Police.
 * Gender Bender: The infamous story from V4 where Shvaughn -- or "Sean" -- reveals that he had been using the drug "Profem" to become a woman so "she" could date Element Lad; unfortunately, the war with the Dominators cut off "her" supply. Jan not only doesn't mind the revelation, he actually implies that he was with "Shvaughn" despite "her" gender. The Postboot Legion stayed clear of the entire issue.
 * Tuckerization: Named after a cousin of a friend of Paul Levitz. He didn't know how to spell the name correctly, however. (53:45 in interview)
