Generator Rex/Characters

These are the characters of Generator Rex.

Rex


Rex is a charming teenager with a sharp sense of humor and a thirst for adventure (at least, if you ask him). He is living the dream as the point man of a high-powered super-spy team and is amazed by the weird world he's a part of, and most definitely digs the spotlight as Providence's weapon of choice. It's like being a super-powered rock star, most of the time. Like any teen, there's a lot going on with Rex that keeps him awake at night – mainly the amnesia that's robbed him of his past. He can't remember anything beyond the few months before joining Providence because they promised to help him learn where he comes from. He is driven toward any clues that might help unlock his memories or better understand and master the strange but wonderful machines banging around inside of him.


 * All the Other Reindeer
 * Amnesiac Dissonance: Before his most recent memory loss, he was a self-centered Jerkass thug who betrayed his best friends out of convenience. After, he's still a jerk, but is willing to risk his life for people he doesn't know all the time.
 * Anti-Hero: Type II. It's pretty unquestionable that at heart he's a good person, but he's also prone to reckless and selfish behavior that can land him in trouble.
 * As of episode 20, this might even be starting to drift into Type III, with a subversion of Save the Villain.
 * He does it again in episode 35,  Notable because there was clearly a more lawful and less violent solution that by all rights Rex would normally be required to take if he was being held accountable. In other words, Rex went out of his way to royally screw an enemy over, possibly to his death, even after said enemy had surrendered and the mission was over.
 * Artistic Age: The fact that he is only 15 came as a bit of a surprise to some viewers; many assumed he was 20-ish.
 * Awesomeness By Analysis: He is apparently consciously aware of the angles and trajectories his ranged weapons need to hit moving targets (Which requires knowledge of Differential Calculus level math at least, although the show only makes mention of Trigonometry).
 * Batman Gambit: Rex manages to pull one of these in "Alliance",
 * Done again in episode 35
 * Brilliant but Lazy: Turns out Rex is actually quite the math prodigy.
 * Justified Trope due to his use of geometry in using the cannon, as explained in show.
 * There were actually indications early on that Rex had some knowledge of electrical engineering and that he had to design his weapons himself.
 * Bunny Ears Lawyer: He's apparently a competent espionage agent in the field, despite blatantly disregarding procedure, and outing himself at the drop of a hat. His When All You Have Is a Hammer mentality tends to make it a somewhat viable approach, though his natural charisma is also helpful.
 * Another instance: in "Alliance" he's able turn two major enemy factions against eachother, create internal strife in one faction, and thwart the villains plans, seemingly all for kicks (his primary objective being something entirely separate). He does this while narrating his every action, even during stealth, and he arbitrarily quits once he gets the two factions fighting.
 * Later episodes do show him being a well-behaved and competent field operative, usually when infiltrating enemy bases.
 * Brown Eyes
 * Chick Magnet: Rex has drawn the attention of Circe, Breach, Annie, Cricket, a high ranking Green Fist eco-terrorist, Dr. Holiday's kid sister, and a random delivery girl. All of them have shown varying amounts of interest in Rex.
 * Chivalrous Pervert: To an extent. He'll hit on women he barely knows, but he's more delicate around anyone he's actually interested in or respects.
 * Character Development: Evident in "Alliance", where he acknowledges his attraction to Circe without it being an issue, whereas in earlier episodes it was a clear distraction. By "Hard Target", he's alright with her dating someone else --the bigger issue is the ensuing three's-a-crowd dynamic.
 * Deadpan Snarker: Coupled with an inability to take anything seriously. Rex is constantly joking, and the more dire and serious things get, the more he dials up the snark. At times, it can get to the point where it seems to be a coping mechanism more than anything else. Which is confirmed in "Heroes United".
 * Destructive Savior: Rex at one point defends his work by saying that he protects people and property, only to quickly amend that he doesn't do as much of the latter.
 * Determinator
 * Divide and Conquer: He has a great talent for getting his enemies tangled up in each other's plans.
 * Dual-Wielding: Averted with his builds outside of using both Smackhands at once--he'd always just rapidly switch between them. Finally lampshaded by Six in "Crash and Burn" who wondered why Rex never did this trope...
 * Face Death with Dignity: Quite possibly the only time Rex ever drops the attitude
 * Genre Savvy
 * Green Lantern Ring: His powers let him create and control machinery, as well as interface with and control any electronic system by touch. It seems to be limited by his mechanical knowledge of whatever it is he's operating. He's able to power up or power down any machine easily, though anything more takes time and effort.
 * Goggles Do Nothing: Averted. Whenever Rex makes a jetpack or hoverbike, the goggles come in handy.
 * Goggles Do Something Unusual: In "Double Vision" his regular goggles are replaced with a more high-tech pair (previously hinted at in "Heroes United") with advanced functions like heat vision, nanite vision, microscopic zoom, and a targeting computer.
 * Good Is Not Dumb: On the surface, he's goofy, self-obsessed, clumsy, and idealistic. However, he's pragmatic when facing foes, and has a keen strategic mind. He's also accomplished enough as a mathematician to consciously apply principles of math and science in combat.
 * Gratuitous Spanish: And Not Even Bothering with the Accent. Both in-universe and out, as well. He does have amnesia, after all.
 * To elaborate, he's ethnically Hispanic, but born and raised around the globe. Cesar notes how he always tried to speak Spanish, with hilarious results.
 * And then lampshaded by Holiday declaring that Rex needs Spanish lessons.
 * The Hero
 * Idiot Hero: Subverted. Despite his Totally Radical mannerisms and eccentric behavior, Rex, while not the smartest guy, definitely isn't dumb, and has played Batman Speed Chess with the big bad on several occasions. Also, he's a highly advanced student of mathematics, and seems have a working knowledge of his weapons' mechanics.
 * Kid Hero
 * Healing Factor: He has a slow one, taking days or weeks to heal serious injuries, putting him in a coma in the meanwhile.
 * Heterosexual Life Partners: With Noah.
 * Hot-Blooded
 * I Just Want to Be Normal: Sort of. Rex loves the action of fighting Evos, but normal life as compared to life working for Providence holds a lot of appeal for him. Basically, he'd prefer if Evo-busting was just his day job.
 * In the Blood:
 * Laser-Guided Amnesia: A chronic ailment, evidently. Periodically, his memory gets wiped, though it's never shown to happen during the time the series takes place. Possibly a side-effect of his nanites.
 * Likes Older Women: 15-year-old Rex really likes hitting on Doc Holiday who is 28, even after he falls for a girl his own age, though it switches to semi-teasing after that.
 * Made of Iron: Even without his constructs to protect him, he's inhumanly durable, being able to (for instance) withstand oceanic pressures that would crush even specifically marine-adapted EVOs.
 * Manipulative Bastard: When he needs to be.
 * Mysterious Past: So mysterious, not even he knows the full extent of it. In fact, he knows less than several other characters.
 * Nigh Invulnerable: He never actually get's a scratch on him, and internal damage is very rarely implied despite the frequently extreme blunt force trauma he normally goes through. Crush-depth pressure doesn't faze him, either.
 * Phlebotinum Overload: Rex's Power Nullifier ability works by absorbing their nanites. If he absorbs too many, it's not pretty.
 * Power Nullifier: He can "shut down" other Evos, permanently reverting them to human form. Unfortunately for him, some Evos are incurable.
 * Psychoactive Powers: If Rex loses confidence, his constructs begin to malfunction and may fall apart.
 * Real Men Wear Pink: He really likes watching telenovelas.
 * Red Oni, Blue Oni: The red to Six and Noah's blue.
 * Required Secondary Powers: Made of Iron, to be specific. He gets thrown through lots of things that a normal person really shouldn't get up from being thrown through. It's later made clear that he has Super Toughness bordering on being Nigh Invulnerable.
 * He's also inhumanely agile; probably one of the most agile characters on the show (given the cast full of Egregious Charles Atlas Superpower, that's saying something).
 * Shapeshifter Baggage: Justified as of "Frostbite". He cures other Evos by drawing their nanites into himself. That's where the extra mass comes from. Once he's drawn in too many to handle, Providence has facilities to remove the excess baggage. It's also been shown that creating his machines does in fact increase his weight.
 * Shapeshifter Weapon: He doesn't have one so much as he is one.
 * Shipper on Deck: With time,.
 * Smug Super: Rex is a mild version of this. Being a teenager with superpowers, it's not exactly surprising.
 * Spider Sense: Played for laughs, he gets shivers when Breach is nearby--it's actually very accurate.
 * Swiss Army Hero: Figuratively (Rex's multiple nanite weapons) and literally (He was born in Geneva).
 * Super-Powered Evil Side: The flashback episode "Promises, Promises" shows that Rex, just prior to joining Providence, somehow built himself into a massive, biomechanical monster that even fighter jets couldn't take down. Doing this wiped his memory. "Assault on Abysus" shows said monster is something he imagined as a kid.
 * Super Prototype: His nanites are from the first batch created prior to the Event. The only stable batch, in fact.
 * Taught By Experience: By the third season it's apparent that Rex is an asset not only because of his combat and curing abilities, but also because of his extensive knowledge of Evo habits and ability to take advantage of them.
 * Technopath
 * Took a Level In Badass: In an interesting twist for a western cartoon, even some of the most dangerous members of Rex's Rogues Gallery pose less and less of a threat to him as the series goes on. There are exceptions,
 * Totally Radical: Justifed, since he has no memory more than about 18 months back, a lot of what he does may just be what he thinks normal teens do - and he probably learned from television since he's always around adults. No other teen in the series acts remotely like this, either.
 * Unwanted Harem: And how! He's garnered the attention of at least six girls in two seasons, though notably one is his villain's misguided Dark Chick, another is the same villain's other Dark Chick who trapped him in a creepy pocket dimension, and the most normal of the girls is a disaster magnet. Long story short, emphasis on "Harem," extra emphasis for "Unwanted."
 * What You Are in the Dark: To a lesser extent, episode five. When outside Providence, he starts stopping random Evo attacks.
 * You Fight Like a Cow: Rex will ALWAYS come up with a smart-ish remark, no matter the situation. In over two seasons worth of episodes, there are extremely few, possibly only one, times that he doesn't snark. It is in fact confirmed to be an act that he puts on to cope with fear.

Agent Six


A senior-level operative for Providence, Six is literally the sixth deadliest man on the planet. Highly skilled in every form of combat and trained in methods of intrigue, Six is the ultimate bodyguard to Rex. His stoic nature and lightning-fast mind have made him a prized operative and explain why he was given the assignment of helping Rex learn how to utilize his powerful abilities. Unfortunately, Six doesn't have much patience for undisciplined partners, unreliable machines and especially smart-mouth teenagers! So from the onset, Rex and Six have an abrasive "odd couple" relationship.


 * Amnesiac Dissonance:
 * Asskicking Equals Authority: Subverted. He's arguably a better combatant than the 2nd through 5th most dangerous people in the world, but he's considered somewhat 'less dangerous' because of his Heart Of Gold.
 * Badass in a Nice Suit: Never seen without his trademark green suit and tie.
 * Badass Longcoat: His winter gear.
 * Badass Normal
 * Bifurcated Weapon: Inverted. If he wants to, he can combine his swords into an electromagnetic weapon with a variety of uses.
 * Blade Below the Shoulder
 * Charles Atlas Superpower: He is much stronger and faster than he has any right to be.
 * The Comically Serious: It's a given if your team consists of a teenager and a talking monkey.
 * Cool Shades
 * Sunglasses At Night: No matter where he goes, even underwater! He finally takes them off in "Divide by Six".
 * Cool Sword
 * Doesn't Like Guns
 * Dual-Wielding
 * Implausible Fencing Powers: He's been shown to cut bullets in half when fired from a machine gun.
 * Intergenerational Friendship: "Friendship" might be a little stretch, but he still looks after Rex in a fatherly way.
 * Jerk with a Heart of Gold: He's incredibly distant, but he's demonstrated his fair share of kind moments. In "The Architect", he finds Rex celebrating with the townsfolk, and radios back that Rex isn't there.
 * In "Wasteland".
 * In "Divide By Six" it's shown that among the most dangerous people in the world he's The Heart of the group.
 * In episode 36, he does whatever it takes to rescue and then cure Holiday's little sister, even seriously injuring himself to try and make the machine work by supercharging it with his magnetic swords.
 * Even when he was a Jerkass homicidal assassin, once upon a time, he wouldn't have been able to kill someone who had absolute faith in him. He also would have made it a priority to live up to the expectations of anyone who cared about him that much.
 * And after the Time Skip, where
 * Known Only By Their Nickname
 * : After a six month Time Skip.
 * The Lancer
 * Laser-Guided Amnesia: Gets hit with this in "Six Minus Six" when saving Rex from a memory recovery device that went wrong.
 * Lightning Bruiser
 * The Men in Black: He has the look and the attitude down. Think Agent K with two fold-out swords.
 * Morality Pet: It's implied Rex is this for him in "Promises, Promises", as he's the one that fought tooth and nail to get him on the team.
 * Officially proven in "Divide By Six" where he said the main reason he never succeeded One was because he met Rex.
 * Shoot the Dog: ... And yet, it's also flat-out stated that if Rex's Phlebotinum Overload hits Super-Powered Evil Side levels, it's Six's job to kill him.
 * Papa Wolf: Lines will be crossed if you hurt anyone he truly cares about. And you do not want that to happen.
 * But then in "Six Minus Six"
 * Red Oni, Blue Oni: The blue to Rex's red. (One of two)
 * The Stoic
 * Sugar and Ice Personality: So much; a prime example would be when In fact, a good chunk of the show's Heartwarming Moments page can be attributed to him.
 * Tall, Dark and Snarky
 * Team Dad
 * Finally admitted by Rex in "Six Minus Six"...
 * The Stoic
 * Sugar and Ice Personality: So much; a prime example would be when In fact, a good chunk of the show's Heartwarming Moments page can be attributed to him.
 * Tall, Dark and Snarky
 * Team Dad
 * Finally admitted by Rex in "Six Minus Six"...


 * You Are Number Six
 * You Are Number Six

Bobo Haha


One of the earliest Providence captures, Bobo is an intelligent monkey who can speak his mind. Despite his darker origins, Bobo has chosen to fight for good in his own gruff way. Bobo is always by Rex's side and fiercely loyal to the boy who saved him. Bobo sports a "shoot then aim" attitude towards every situation that he and Rex find themselves in and is constantly giving absurd advice to Rex, encouraging his more mischievous side.


 * Barefoot Cartoon Animal: Being a monkey, it would be pretty stupid of him to cover his prehensile feet with shoes.
 * Berserk Button: Do not interrupt his nap.
 * The Big Guy
 * Crouching Moron, Hidden Badass: He doesn't tend to do much, but the flashback episode revealed that he used to do things like sneak into the Kremlin and try to press The Button...for fun.
 * Deadpan Snarker
 * Energy Weapons: His blasters, though they're rarely all that effective.
 * Everything's Better with Monkeys
 * Eyepatch of Power
 * Funny Animal
 * Guns Akimbo
 * Insistent Terminology
 * Jerk with a Heart of Gold
 * : After a six month Time Skip.
 * Nice Hat
 * Non-Human Sidekick
 * : For the new Providence.
 * Talking Animal: Bobo's speech is a side effect of his Evo mutations.
 * The Worf Effect: If he's involved in a fight, he tends to get knocked out of it before getting a chance to do much - and even if he isn't, he rarely accomplishes a great deal anyway. Averted, big-time, in "Robo Bobo."
 * The Worf Barrage: Despite looking thoroughly impressive, those energy blasters of his don't have a much better track record than regular Providence solid-shot weaponry.

Noah Nixon


Noah is in every way a regular kid, except for one thing: he is secretly employed by Providence to be Rex's friend. This deception ultimately weighs heavily on Noah, who genuinely likes Rex. Noah provides a dose of reality and normalcy in Rex's life and is there for him, whether it's to play a game of basketball or to offer advice.


 * The Ace: It's eventually shown that Noah does in fact have his act together very well, being popular, intelligent, and surprisingly well-connected in school and life, as well as being a veteran, if not well practiced, combatant. Rex, by contrast, is a clumsy goof around people his age.
 * Action Survivor: After a short stay at Providence boot camp, he's more than willing to grab a gun when it comes to that.
 * Alliterative Name
 * Blue Eyes
 * The Chick: He has no powers or special abilities, but is valuable to Rex due to the emotional support he provides him with.
 * Conflicting Loyalty
 * Heterosexual Life Partners: Becomes truly good friends with Rex, even letting him stay at his house when Providence HQ was under construction.
 * Ordinary High School Student: Double Subverted; he looks the part, then his secret is out, and then it's revealed that he is by all means a high school kid with normal problems other than Providence.
 * Red Oni, Blue Oni: The blue to Rex's red. (One of two)
 * Took a Level In Badass: After going through some Providence basic training (even though he technically dropped out) he's shown the ability to use the Providence assault rifle and even.
 * Unfazed Everyman

Dr. Rebecca "Doc" Holiday


Genius scientist extraordinaire, Doctor Holiday works for Providence as tech support, but her main focus though, is Rex. She monitors his emotions, the state of the nanites inside him and his general health. Holiday has taken a much more maternal interest in Rex, and seems to be the only person at Providence who truly cares for his emotional well-being. Holiday is not afraid to speak her mind and though she respects authority, she answers first and foremost to science. She's quickwitted, clever and direct. It's almost always impossible to pull something over on Holiday.


 * Action Girl
 * Ambiguously Brown: She may be Asian, or part Asian, or just plain White. It's hard to tell.
 * Badass Bookworm: When you consider the fact that she's more scientist than Action Girl.
 * Brainy Brunette
 * Combat Pragmatist: In contrast to Six, she usually fights with heavy artillery.
 * Cool Big Sis: With some flavor of Big Sister Instinct when it comes to Rex
 * Education Mama: Apparently becomes one to Rex at the end of "Without A Paddle." Played for laughs.
 * Green Eyes
 * Hot Scientist
 * Ink Suit Actor: Her design arguably resembles her voice actress, Grey DeLisle.
 * Knight Templar Authority Figure: Though not technically his mother, she'll be absolutely ruthless to anyone she knows has hurt Rex (not that Rex can't take care of himself, mind you, but in situations where he's unable to act).
 * : After a six month Time Skip.
 * Lethal Chef: For all her technological/medical skills and sexy labcoat, she can somehow manage to make a cake that requires no less than an authentic Japanese tanto to cut. (With Rex and Six expressing uncertainty as to whether even that would be sufficient.)
 * Letting Her Hair Down: Inverted; it was down when Rex was first brought to Providence. Seems she tied it up later.
 * Mama Bear
 * Minored in Asskicking
 * Mission Control
 * No Nudity Taboo: When it comes to her patients, at least, but being a doctor, it's understandable and not unusual.
 * She will, however, mock their.
 * Parental Substitute: The closest thing Rex has to a mom in the series.
 * Shipper on Deck: For Rex and Circe.
 * Team Mom
 * Tsundere: A type B towards Six.
 * The Smart Girl

White Knight


The Agent in charge at Providence, his ultimate quest is to rid the world of E.V.O.s (Exponentially Variegated Organism). White harbors an almost irrational fear of nanites, to the point where he never leaves his stark white office, which also doubles as a high-tech nanite-free clean room. As far as anyone can tell he never leaves the sterilized room he calls an office, as apparent by his flour white skin and that he keeps a jar of milk in a drawer. While there is not exactly a heart of gold hidden beneath his gruff exterior, he does genuinely want to do the right thing, and is often faced with making really tough decisions. Once a friend and partner of Six, their relationship is showing signs of serious strain.


 * Anti-Hero: Type V.
 * He's stepping down a bit. He can be reasonable, and it's shown that he is a competent, if stern and cynical, leader.
 * Authority Equals Asskicking: He may be the boss and a shut-in most of the time, but when he does need to kick ass, he can.
 * Before he was the boss, WK was a competent field agent for Providence. He even fought  in hand-to-hand combat and did pretty well for himself.
 * Back-to-Back Badasses: He and Six used to be this, back when he was actually in the thick of it during the early days of Providence.
 * Big Good: Just barely. He is in charge of Providence and all of the good guys, but it's a stretch to call him a good person.
 * Bubble Boy: He has a good justification for this in "The Plague". Being the only person on the planet free of nanites, he's the only living human who can be unquestionably trusted not to go Evo and turn on his own people at a bad time. What's ironic about it is that he wasn't always uninfected; he was stuck in a molecular deconstruction chamber which should have killed him, but Rex shut it off just soon enough for it to remove only his nanites.
 * Crazy Prepared: He has a Mini-Mecha if he has to go outside. If that's destroyed, he's wearing another suit of powered armor under that. And that suit of armor is modular with redundant sections in case it's damaged.
 * Defrosting Ice Queen: A male version to Rex as of "Payback". He seems to appreciate Rex much more as a person AND ACTUALLY LAUGHED AT SOMETHING REX SAID.
 * And later in Heroes United (which despite being a crossover, is canon for GR), he opted to stay and fight Alpha with Rex and Ben, despite the fact that if his armor took any more damage he'd be exposed to nanites for sure. Why?
 * Jerkass: Knight doesn't really do 'polite', let alone 'cordial'.
 * Later episodes have him developing into a Jerk with a Heart of Gold.
 * Kill'Em All: Though he at least is willing to try less extreme methods before resorting to this.
 * : After a six month Time Skip.
 * Locked Into Strangeness: His hair and skin color are the result of the accident that removed all the nanites in him.
 * Man in White
 * Mini-Mecha: Even though he's paranoid about being infected by nanites, this hasn't stopped him from building one of these so he can go on missions when he absolutely has to.
 * Not So Stoic: As evidenced by 'Grounded', Knight does have a sense of humour. It's not particularly nice, but it's there.
 * Perpetual Frowner
 * Pet the Dog: Want to know how he lost his nanites? He pulled a Heroic Sacrifice to save Six's life. He only survived due to Rex's intervention.
 * And in Heroes United he risks being infected again to help Rex and Ben.
 * Powered Armor: Wears it beneath the mecha.
 * Start My Own:
 * Super OCD: A more subdued example then usual, but even before the E.V.O. incident, he was said to have a problem with germs.
 * We Have Reserves: He berates Rex for saving soldiers, at one point saying that they knew if they died, they'd be replaced.
 * Well-Intentioned Extremist: Bordering on Knight Templar. He backs away from that sometimes, but is always this trope at best.

César Salazar
one of the scientists who worked on the nanite project. He managed to escape the lab he worked in before the nanite explosion, only for his portable lab to move at light speed(!) for 15 minutes (5 years in real time). Knew Van Kleiss and Rex before the nanite incident. "Caesar: "You mess with my brother, you mess with me." Cain: "Who are you? You an EVO?" Caesar: "No, I'm a scientist" *shocks Cain with a probe*"
 * Absent-Minded Professor: He's a genius and a nice guy, but a little... kooky.
 * Attention Deficit Ooh Shiny
 * Cannot Spit It Out: He has an amazingly bad habit of refusing to volunteer any information unless he feels like doing so. It took an entire season just to get him to reveal the truth behind the nanite event.
 * Cloudcuckoolander
 * Crazy Prepared: And yet he didn't think to install a  on his ship.
 * Crouching Moron, Hidden Badass: Notable in that the badass part comes before the moron. Sure, he's a goofball and Cloudcuckoolander, but he pretty much upstages Providence in his debut episode with his technical prowess and knowledge of nanites. Rex does stop him before he takes on Six, but hey, that's pretty good for a guy who's technically a non-combatant.
 * He isn't afraid to go up against the likes of Hunter Cain to defend Rex, as seen in "Night Falls". Papa Wolf Mode kicks in.


 * Ditzy Genius
 * : After a six month Time Skip. Includes a.
 * I Did What I Had to Do:
 * Implacable Man: Upon his introduction. His suit and the machine he used to disable Providence tech couldn't be stopped by the veritable army that was thrown at him.
 * In the Blood:
 * He finally got
 * Mad Scientist: He created . Granted, he (probably) wasn't responsible for any of its mishaps...
 * In "Written In Sand" Van Kleiss flat-out states that . Eventually, Cesar
 * Mike Nelson, Destroyer of Worlds: He has good intentions (sort of) but his inventions have come dangerously close to ending all life on Earth several times. It's hard to think about what would happen if he was trying to do intentional harm to humanity.
 * Nice Job Breaking It, Hero:
 * Not Distracted by the Sexy: The one thing he doesn't seem distracted by. The most he can say about Doc Holiday is that she seems "very smart." Rex is stunned by this.
 * Although not distracted, he is aware of her good looks, as he had referred to her as "bonita" (means 'beautiful' in Spanish) in his debut episode while rescuing Rex.
 * Not So Harmless: Can throw down when the situation requires...also, there are some very, very dark hints from Van Kleiss that
 * The Spock
 * Too Clever by Half: Smart enough to make advanced artifical intelligences-too much of a Ditzy Genius to program appropriate safeguards.
 * Well-Intentioned Extremist: Whatever he's up to while working for Black Knight he apparently think it justifies the means no matter what. The other scientists who worked on the nanite program appear to agree with him too.

Captain Calan
Providence Captain, and major ally to White Knight. He makes several appearances throughout the show.


 * Badass Normal: Not to Six's extent, but he's still competent in a fight
 * Good Scars, Evil Scars: has a scar over his eye. As seen in Promises Promises; he got it in the five years from when Rex was recruited, to the present.
 * Mauve Shirt: The most important/recurring providence agent outside the main protagonists/antagonists.
 * Undying Loyalty: To White Knight
 * Undying Loyalty: To White Knight

The Consortium
The Consortium is a powerful organization which supports Providence and functions as the superiors of White Knight and Black Knight. Little is known about this organization, but they seem to provide funding for Providence and the Nanite Project.


 * A God Am I: The Consortium wish to use the Meta-Nanites to take over the world and to become gods. Before that, they funded the Nanite research that resulted in those Meta-Nanites as well as the Nanite dispersal event, in order to gain immortality.
 * Awesome McCoolname: All of the male members have very cool names. Xanubian? Sir Anthony Haden-Scott?
 * Bigger Bad
 * Color Coded for Your Convenience:
 * Evil Is Petty:
 * Greed:Black Knight mention of them having greed being their common goal
 * Politically-Incorrect Villain: They're all mildly misogynistic.
 * Greed:Black Knight mention of them having greed being their common goal
 * Politically-Incorrect Villain: They're all mildly misogynistic.
 * Politically-Incorrect Villain: They're all mildly misogynistic.

Black Knight
"Gender: Female Profession: Providence Councilwoman,, Voice Actor: Jennifer Hale"

Though she is at all times polite and kind, her methods and motives are questionable at best.


 * Action Girl: Much like Holiday. Though she tends to stay out of the action, she often leads from the front lines.
 * Affably Evil: Offers Rex refreshments and is nothing but courteous in their first meeting, and is polite and even soft-spoken at all times.
 * Anti-Villain: Type III.
 * Berserk Button: Though it would probably piss any woman off, the Consortium's misogynistic attitude toward her clearly doesn't do wonders for her loyalty, . Also, do not call her "little lady".
 * Black Knight: In name only
 * Dark Is Edgy
 * The Dragon: To the Consortium, who run Providence. By comparison, White Knight didn't really tow the line.
 * The Starscream: She's made it clear she'll betray them for personal gain. Unfortunately for her, White Knight got a recording of her saying this, and will pass it on to the Consortium if she goes after him again.
 * Dragon Ascendant: Working this angle, too.
 * Eerie Pale-Skinned Brunette
 * Eviler Than Thou: She's nicer than White Knight in personality, but her methods are even more radical.
 * Friendly Enemy: While she and Rex are nominally on the same side, she has an almost inhuman patience for his flouting the law and undermining her efforts. She doesn't seem to have a problem with them chatting her up on missions, and is willing to work with them in a crisis. She also has an open offer of  for Rex which she brings up often. All this despite
 * Knight of Cerebus: It's always been a pretty dark show, but it got significantly darker when she took over Providence.
 * Knight Templar: Best seen in "Riddle of the Sphinx", where she destroys some very valuable scientific and archaeological finds due to the dangerous and questionable nature of the information they held. She does it with rockets and explosions.
 * Nerves of Steel: Never fully drops her composure, though she is visibly agitated on occasion.
 * Paint It Black: Repainted White Knight's office pitch. Her personal guard also have black uniforms distinguishing them from Providence grunts.
 * Peek-a-Bangs
 * Putting on the Reich: The cape normally obscures it, but her outfit has some definite similarities to the Third Reich's uniform of choice.

Roswell
"Gender: Male Profession: Consortium Member Voice Actor: Troy Baker"

A business mogul hailing from the south. Brash and blunt, Roswell demands results more so than details. Black Knight's presentation on the Meta-nanites intrigued Roswell, which influenced him into following Black Knight's lead in return for power.

Reddick
"Gender: Male Profession: Consortium Member Voice Actor: Robin Atkin Downes"

A real estate and construction magnate, Reddick first appeared at Black Knight's presentation on the Meta-nanites at a Providence facility with the rest of the Consortium. To Black Knight's dismay, Reddick wasn't particularly impressed by her efforts.


 * Flat Character: He doesn't do much...

Xanubian
"Gender: Male Profession: Consortium Member Voice Actor: None."

An arms dealer masquerading as an industrial shipping professional. He first appeared, along with the rest of the consortium, at Black Knights Meta-nanite presentation. He prefers to listen before voicing an opinion.

Vostok
"Gender: Male Profession: Consortium Member Voice Actor: John DiMaggio"

A KGB agent working as a black market money-lender. Vostok first appeared at a meeting held with Black Knight and the Consortium. He seemed to have much doubt with whatever Black Knight presented to them about the meta-nanites and the nanite project.

Van Kleiss


Van Kleiss is described as every mad scientist you ever saw only a lot freakier and dangerous. His body's molecular structure is unstable and thus has to stabilize himself using Nanites extracted from Evos captured by the Pack and experimented upon by him. He possesses the ability to control everything in his Kingdom Abysus but out of his territory he cannot use his powers. He knows a great deal about the Nanites which causes Evo Mutations and about Rex's past (implying he had a hand in his mutation) he states that he will tell Rex everything but only if Rex joins his team.


 * Achilles Heel: He is powerless unless he is on his native soil. He spends a lot of time trying to get around this, while at the same time exploiting his own weakness so people won't think he's a threat.
 * And I Must Scream: After "Lions and Lambs" Van Kleiss was sent to ancient Egypt. While there, he became aware of a cosmic presence trying to eliminate him because of his tampering with history. He decided he needed to get back to his own time, and so built a device to do so. Unfortunately, the device he used (resembling a sarcophagus) opened up way too early, landing him in ancient Rome. He repeats the process again and again, rebuilding the device in each era, each time traveling a little further into the future, constantly terrified of the presence following him..
 * Asskicking Equals Authority: His modus operandi in a "Brief History of Time" was to fight his way through warrior ranks (largely without his powers) until everyone was convinced he was a god, and then to commandeer a lab and revolutionize the local civilization until technology was good enough for him to make a Time Machine.
 * Attack of the 50-Foot Whatever:
 * Badass Abnormal: Somewhere between "scientist", "ruler", and "EVO vampire", he found the time for "absolutely Badass swordsman."
 * Badass Longcoat
 * Badass Long Hair: Rex has even made a few comments about it.
 * Bad Boss: When the newest member of the Pack cripples Van Kleiss' nanite suit, he petrifies the Evo on the spot.
 * Batman Gambit: All of his plans, most notably when he takes over New York.
 * Beard of Sorrow:
 * Big Bad/Evil Genius
 * Brought Down to Normal:
 * Brought Down to Badass: "A Brief History of Time" has him with limited use of his powers for the episode. Despite this, he is shown to be a very Badass warrior. Enough to eventually gain control over the local kingdom. On multiple occasions. In multiple eras.
 * Came Back Wrong: Leaving him curable.
 * Cloudcuckoolander: Following his And I Must Scream incident.
 * Control Freak: As Rex points out at least once, Van Kleiss has to be in charge. This has actually ended up scuppering his plans on a couple of occasions, not least because of the lack of faith it implies in his subordinates.
 * Discard and Draw: He lost his powers when Rex cured him,.
 * Eerie Pale-Skinned Brunette
 * Evil Genius: The sheer scope of his knowledge, scientific or otherwise, is incredible. He was apparently a programmer of some sort while working with Cesar, but he displays mastery of metallurgy, weapons crafting, quantum and relativistic physics, electrical and mechanical engineering, all kinds of biology, ancient dialects of multiple linguistic families, anthropology of ancient civilizations, and infrastructure development on a grand scale. In most of these, he has complete and total mastery, as he is able to develop those fields past modern levels from first principles.
 * Emperor Scientist
 * Expy: Resembles Kevin 11 from Man of Action's previous show crossed with Orochimaru.
 * From Nobody to Nightmare: According to Cesar, he was a minor lab technician before the Incident. Cesar turns out to have been understating his importance, but nevertheless he was hardly at the forefront of the project.
 * Genius Bruiser: While Van Kleiss has always been a formidable opponent, it could usually be attributed to his powers and/or plans. However, "A Brief History of Time" shows that, when powerless, he is an extremely good fighter. In each era and location he visited, it seems he became a warrior of some sort(a gladiator in Rome, a Samurai presumably in Japan, etc.), and even knew the local language fluently, bumping him up to near-Crazy Prepared.
 * Genius Loci
 * Green Thumb
 * Fertile Feet
 * Good Thing You Can Heal: His original powers allowed him to regenerate from the land around his palace, no matter how badly injured. He presumably lost it once cured.
 * Horror Hunger: Before he was cured, at least.
 * Humanoid Abomination
 * Important Haircut: Averted, He didn't cut off his hair, But he shaved off his beard instead.
 * Joker Immunity: But justified by his being nearly impossible to kill. Lately, he's just a lot more careful.
 * Long-Haired Pretty Boy: an older example.
 * Manipulative Bastard: He's very good at this, though we haven't seen enough of his long-term plotting to tell if he qualifies for Magnificence or not.
 * While his latest scheme,, backfired pretty hard, he still ended up a lot better off than he would've been without it. As of episode 21 however, Van Kleiss may just met these qualifications.
 * Mook Maker: His new power.
 * Omnidisciplinary Scientist: He certainly has the greatest scope of knowledge of any scientist in the series, though he's not necessarily as successful on the cutting edge.
 * Omniglot: "A Brief History of Time" shows that he knows a lot of different languages, and even specific dialects therein.
 * Our Vampires Are Different: Nano-vampire, technically, before being cured. Still has some vampiric traits.
 * Out-Gambitted:
 * No Name Given: We're never given his first name. Three seasons, 60 episodes.
 * Power Parasite: After getting depowered by Rex, Van Kleiss stole Rexs' Nanites and depowered him as a result. He gets powers opposite to Rex's -- creating Evos.
 * President Evil: He's the legally recognized ruler of Abysus, which he exploits particularly in the seventh episode by invoking diplomatic immunity--and it works until that little business with holding the UN hostage...
 * Put on a Bus: Twice. It takes about a half-season for him to return each time.
 * Red Eyes, Take Warning
 * Royals Who Actually Do Something: By implication. He's been a legally recognized ruler for some time, but seems to have been a professional researcher since before the nanite event.
 * Well-Intentioned Extremist: He claims to be merely working to create a better future for all EVOs, but we don't know how much he really buys into that, and how much is just propaganda.
 * You Have Failed Me: Does this to Nightshadow in "Dark Passage" after he

Biowulf


An armored werewolf-like Evo with super human abilities, Biowulf is fiercely loyal to Van Kleiss. Due to Van Kleiss powers being limited to his native soil, Biowulf acts as the Pack's de facto leader.


 * Big Badass Wolf
 * The Dragon
 * The Faceless
 * Red Eyes, Take Warning
 * The Renfield: While not as apparent as other examples, he becomes very defensive when he believed his role as Kleiss' #1 minion would be taken from him.
 * Talking to Himself: Van Kleiss and Biowulf are both voiced by Troy Baker.

Breach


Breach can open portals from anywhere to anywhere else, making her the Pack's main form of transportation. In addition to that, she can also fire the portals at her enemies like shuriken and send attacks through them. With these Evo powers and Breach's insanity, make her the Pack's most unpredictable member.

It was later revealed that she took the city of Greenville, OH and turned that place into her personal dollhouse. She uses this "dollhouse" to keep "shiny things" and have captive Evos fight each other.


 * Audio Erotica/Vocal Dissonance: Her voice is considerably cuter than she is. Though when she starts showing her face more, it turns out she's actually pretty cute.
 * Axe Crazy: Dear lord, yes.
 * Berserk Button: She doesn't like it when you break her "toys".
 * Blue and Orange Morality: Outwardly, it seems like she's just a Psycho for Hire mook. It turns out that she's doing it for neither money nor Van Kleiss' vision of world domination (though she pays that lip service). She for some unfathomable reason seems to pick "favorites" to whom she'll be predisposed to trust. In Van Kleiss's case, it manifests as devotion, to the point of withstanding abuse and torture. All of which she justifies with an absolutely skewed sense of reality.
 * Collector of the Strange: Her "dollhouse" has Evos, Creepy Dolls, and ice cream trucks.
 * Not to mention the dollhouse itself is Greenville, Ohio.
 * Cute Monster Girl
 * Dark Chick
 * Disney Death
 * Eerie Pale-Skinned Brunette
 * Expy: Of Sadako.
 * Extreme Doormat: For Van Kleiss, since he's one of her "favorites".
 * Fire-Forged Friends:
 * Green Eyes
 * Hidden Eyes: Constantly in use in her earlier appearances, and frequent even once her face was shown.
 * Living Doll Collector
 * Mind Screw: Her portals can lead to other dimensions, complete with altered physics and trippy space imagery (possibly also a part of her mind). A lot of the things she says in "Lions and Lambs" counts.
 * Multi-Armed and Dangerous
 * The Ophelia
 * Sanity Has Advantages: If she wasn't so childish and crazy, she'd be far more dangerous than Van Kleiss.
 * Stringy Haired Ghost Girl: Definitely based on them.
 * Strange Girl
 * Suddenly Voiced: Okay, so she talked a little before "Hard Target", but the number of lines she had in the first half of that episode alone was maybe four times the number she had in every other episode combined. Plus we got to se her entire face twice.
 * Super OCD: Do not mess with anything in her dollhouse dimension.
 * Tears of Blood:
 * Teleporters and Transporters
 * Villainous Breakdown
 * Wall Crawl: While she doesn't get mch mileage out of it due to her portals being far more useful, Breach has been shown to be able to cling to walls.
 * Yandere/Cute and Psycho: She's quite fond of Rex, but very unhealthy about it. Rex seems to think its a romantic thing, but Breach's perspective on the situation isn't entirely clear.

Skalamander


A humanoid lizard Evo with crystal spikes growing out from all over his body and a crystal club growing out of his left arm. He can fire said spikes out of the club or grow it into a shield, providing short or long range attacks, as well as defensive abilities.


 * The Brute: Partially subverted. Though he's definitely the team muscle, he's less aggressive than he looks and actually tries to keep the peace between the Pack and Providence at the begining of Leader of the Pack.
 * Dumb Muscle: He's clearly not the most articulate member of the Pack.

Circe
See Rex's Old Gang

Nightshadow
Nightshadow is an EVO that was seen having joined The Pack shortly after Breach's disappearance, and helping Van Kleiss look for Dr. Rylander's laboratory. He accidentally cuts one of the pipes providing Van Kleiss with Abysus. He was drained of nanites by Van Kleiss, and turned to stone...


 * Boisterous Bruiser: On one occasion, he's dealing with a pack of Providence grunts when he spots Black Knight about to take one of the Meta-Nanites. He beans her with a Providence soldier to stop her. Cue epic victory pose.
 * Determinator:
 * In Universe Nickname: Rex refers to him as "the cat".
 * Mistreatment-Induced Betrayal:
 * Not Quite Dead:
 * Not So Above It All: He comes off as a super-efficient hardass, a la Six, but he's got an eccentric sense of humor.
 * Revenge: Wants it on Van Kleiss, but he's reasonable enough not to let it completely control him.
 * Superpower Lottery: Were it not for the outward mutation, he'd have hit the jackpot. Strength, speed, claws, cloaking, voice mimicry; he's got the complete package.
 * Taken for Granite:
 * Voice Changeling: Revealed in his second appearance.
 * What You Are in the Dark:
 * You Have Failed Me: Van Kleiss casually murders Nightshadow for damaging his nanite dirt suit.

The Six
A group of mercenaries comprised of the six most dangerous people in the world. Six was a member before joining Providence in hopes of finding a cure for his master, One, who is slowly turning into a full E.V.O.

Tropes they all share

 * You Are Number Six: None of them has revealed their real names. Their alias/code names are word plays of their rank within the group according to how dangerous they are.
 * Badass Normal: They may not be E.V.O.s but they are skilled enough to fight one such as Rex. Being the most dangerous person on the planet will make you this.
 * Improbable Weapon User: All of them except for Tray who doesn't use any weapons at all.
 * Especially IV who, for some reason, is able to control the bandages that he's wrapped in.
 * Five-Man Band / Five-Bad Band: Their alignment is ambiguous, being mercenaries and all, though their willingness to kill seems to point to the evil direction.
 * The Hero / Big Bad: One (Turned E.V.O. )
 * The Lancer / The Dragon: Dos (The team's current leader. His name is Spanish for 2.)
 * The Big Guy / The Brute: Trey (Not actually his real name. Stands for 3.)
 * The Smart Guy / Evil Genius: IV (Roman numeral for 4. Read as "Ivy".)
 * The Chick / Dark Chick: Five (Despite what her trope implies, is actually quite the opposite of "dark" .)
 * Sixth Ranger: Six (Joined Providence.)
 * Weapon of Choice: Each of them is specialized in using the weapon of their choice and seem to refuse to use any other weapon but their own.

One

 * Badass Grandpa: He was the most dangerous man in the world before he turned into an E.V.O.
 * Determinator: Holds off from going full EVO for five years on sheer willpower alone.
 * The Obi-Wan
 * Parental Substitute: For Six.
 * So Proud of You:.

Dos
"Dos: Like you lent me a hand in Buenos Aires?"
 * Badass Grandpa: He's the oldest of the five we see, and the Second most dangerous man on the planet.
 * Badass Spaniard
 * Cane Fu: When he's not using the sword inside.
 * Eyes Always Shut
 * Instant Sedation
 * Noodle Incident:


 * Spexico: Averted. Rex asks him if he's Mexican. He replies with "España!"
 * Sword Cane

Trey

 * Badass Normal
 * Dumb Muscle
 * Ragin Cajun

IV
"IV: It's like a Roman 4."
 * Badass Abnormal: Not an Evo, but can still manipulate his bandages at will.
 * Bandage Mummy
 * Deadpan Snarker
 * Noodle Incident: The Malaysian job. He lost a pinky, apparently.
 * Token Minority: The only black guy in the top 6.
 * Viewers are Morons:


 * Lampshaded by Rex.

Five

 * Badass Normal
 * British Accents: has a bit of a Cockney accent.
 * Instrument of Murder: She fights with a guitar.
 * Most Annoying Sound: In universe example. She gets royally annoyed at everything Trei says.
 * Rose-Haired Girl
 * Shipper on Deck: For Six and Holiday.
 * Stealth Hi Bye: Remarkably good at it, given the pink hair and garish punk-rock outfit.
 * Third Person Person
 * You Gotta Have Blue Hair: Well, pink. Almost certainly dyed.

Six
See Providence.

Circe


Circe is very similar to Rex, as she looks perfectly human until she starts using her powers. She has a secondary mouth which she uses to fire sonic screeches at her enemies. Her reasoning for why she has teamed up with the Pack is because she feels like too much of an outsider to go anywhere else. Rex constantly tries to get her to switch sides.


 * Bad Powers, Good People: Despite her astonishingly freaky-looking mutation, she's one of the nicer EVOs.
 * Beauty Is Never Tarnished: Strongly averted with her powers, which rip her face open every time she uses them.
 * Birds of a Feather/Not So Different: With Rex.
 * Conflicting Loyalty
 * Dark Chick
 * Dark Magical Girl
 * Dating Catwoman: She really does want to be friends with Rex, but the Pack isn't exactly happy with that...
 * Van Kleiss, on the other hand, is more than willing to use this as part of his long-term plan to get to Rex.
 * Deadpan Snarker: At times.
 * Game Face: Before she uses her powers, she does this Xenomorph thing with her mouth.
 * Emo Teen: Looks like one, anyway.
 * Heel Face Turn:
 * Horrible Judge of Character: She had the delusion that Van Kleiss somehow cared about her.
 * I Just Want to Be Normal: Though she seems to be missing the fact that she doesn't look anything like a monster-EVO until she voluntarily uses her powers...
 * Lady in Red
 * Lovecraftian Superpower: Activating her EVO abilities involves turning her lower face into a biological sonic cannon, complete with razor-sharp fangs and torn skin.
 * Make Me Wanna Shout
 * Meaningful Name
 * Eerie Pale-Skinned Brunette
 * Red Eyes, Take Warning
 * Weirdness Magnet: Circe claims to be this, but it's not clear if it requires her to actually use her powers. Assuming it's passive would explain I Just Want to Be Normal, since her only means of defending herself from the Evos attracted to her would be using her more conspicuous powers. It also has some interesting implications for her relationship with Rex, who is, you'll recall, an Evo himself.

Tuck

 * Mummy: Sort of. He's all bandage and no mummy.
 * The Lancer: Was apparently this back when Rex was with the gang.
 * She Is Not My Girlfriend: Cricket, that is.

Skwydd

 * Cthulhumanoid
 * Deadpan Snarker: Has shades of this.
 * Jumping on a Grenade: Sort of. In "Lost Weekend," his abilities are temporarily modified so that his smokescreen comes out solid, and he uses this to contain an exploding EVO.
 * She Is Not My Girlfriend: With Circe.
 * Smoke Out: He can breathe smokescreen.

Cricket

 * Cute Monster Girl
 * Everyone Could See It: Apparently she had a crush on Rex when he was with the gang, and he was either oblivious or pretending to be. It's hard to say; he was kind of an asshole back then.
 * He Is Not My Boyfriend: Tuck.
 * Lightning Bruiser

ZAG-RS

 * AI Is a Crapshoot
 * Big No: First appearance in episode 5.
 * Grey DeLisle
 * Kill'Em All: Anything with nanites, at least.
 * Destroy All Humans!: Which is almost every living thing on the planet in the series.
 * Manipulative Bitch: She's very good at getting humans to do what she wants, first tricking an entire colony of people into helping her build a Doomsday Device and in her second appearence
 * Not Quite Dead: Even if it showed up out of pretty much nowhere, this was pulled quite nicely in Gravity. Twice!
 * Omnicidal Maniac: Has absolutely no problem killing all life on Earth (well except White Knight, who is uninfected) just to protect herself.
 * Omnicidal Maniac: Has absolutely no problem killing all life on Earth (well except White Knight, who is uninfected) just to protect herself.

No-Face

 * Authority Equals Asskicking: Dear god, does it ever. His debut episode was one thing. When next he shows up, he takes on Rex and the Pack (separately) and was easily a better fighter than all of them. This is not an Evo to be taken lightly.
 * Badass Decay
 * The Faceless:
 * Mission Control: Coordinates the other Evos in the Bug Jar to make them more effective.
 * Multi-Armed and Dangerous
 * Sealed Evil in a Can: He's trapped inside the Bug Jar. And he wants out!
 * Villain Team-Up: Van Kleiss tries to orchestrate one with him.  Happens again in "Enemies Mine", which worked better since all involved wanted Rex dead. Not that they succeeded, of course.
 * Telepathy: How he controls the other Evos.
 * Telepathy: How he controls the other Evos.

Hunter Cain

 * Actor Allusion: Able to rouse people into a frenzy and get them on his side? Yep. Super strong? Definitely. Does anyone know a wrestler like that?
 * Bald of Evil
 * Fantastic Racism: Hates all Evos after his own wife transformed into one.
 * Hypocrite: Despite making it his goal to destroy EVOs, near the end of his debut episode, he admits that he created the ones that his men and Rex were currently fighting to discredit Rex and prove he was better. He also teams up with No-Face in a later episode, which Rex immediately calls him on.
 * I Call It Vera: His BFG, Sweet Caroline. It's presumably named after his wife who turned EVO.
 * In The Name Of Cain: Although it's never stated how to spell it.
 * It's Personal: His grudge against Rex and all other Evos.
 * John Cena: Who voices him in his debut episode.
 * John Dimaggio: Who voices him after the debut.
 * Kill'Em All
 * Spell My Name with an "S": How are we supposed to spell his name, exactly?
 * Villain with Good Publicity: Very popular as shown in his debut episode until he's exposed for creating EVOs to gain said publicity.

Claire Bowman and Annie
A pair of "normal" teenage girls that go on double dates with Rex and Noah. They're both scientific prodigies and Annie has notoriously dangerous bad luck. So bad that Noah recruited Rex to go out with her because he didn't think anybody else could survive the experience.

 * Cute Clumsy Girl: Annie

Gatlocke
"Rex: I've got the right here! Back off or I'll send us all to Kingdom Come! Gatlock: You wouldn't dare! Rex: Or would I? You said you and I are a lot alike... Gatlock: You would."
 * Affably Evil
 * Arm Cannon
 * Badass Normal: Barely. He has cybernetic arms. Otherwise, holding his own against Rex in a swordfight is pretty badass.
 * Berserk Button: Do NOT call him "common."
 * Blade Below the Shoulder
 * Card-Carrying Villain: He is unabashedly this, and readily admits it.
 * Equal Opportunity Evil: There are no ladies in his gang. He thinks something needs to be done about that.
 * Foe Yay: Every other sentence in his fight with Rex was something like "Oh, I like that!" or "I've got a serious case of Evo-envy!"
 * Large Ham: Oh god, is this guy chewing the scenery... In fairness, he does seem to be aware of his hamminess, and enjoys it quite a bit, sort of like an in-universe example of Ham and Cheese...
 * Not So Different: Played straight and inverted.


 * Pirate: Desert variant, though he wonders if the spyglass is too cliche.
 * Ironically, his voice actor portrays a non-pirate character in a famous movie series about pirates...
 * A Pirate 400 Years Too Late
 * Shadow Archetype: He feels like one for Van Kleiss.
 * Wolverine Claws

Branden Moses

 * Blond Guys Are Evil
 * Bitch in Sheep's Clothing

Quarry
A Evo crime lord who Rex used to work for, prior to losing his memories.


 * And I Must Scream: Even shattering him apparently doesn't kill him. It does make any sort of communication rather difficult, though.
 * Detachment Combat: In his third appearance, he can use his fist like a whip. This is apparently because...
 * Literally Shattered Lives: It's all but stated outright that Van Kleiss punished him for his betrayal by breaking his body apart. His new outfit is apparently the only thing holding him together. Taken a step further when Rex hits him with his spinning giant fist, outright shattering him into chunks.
 * Taken for Granite: His mutation turned him into living stone.

Rand

 * You Gotta Have Blue Hair

John Scarecrow

 * A House Divided: Part of his Shapeshifter Guilt Trip Tactics.

 * Voluntary Shapeshifting

Alpha
Alpha is the original control nanite created by but sent to an empty dimension, where he started attempting to merge with organic lifeforms in his pursuit of a stable body. Unfortunately, that universe turned out to be the Null Void. He found a host and forced a return to Rex's world, accidentally taking Ben with him and setting up the crossover.

"Alpha:"
 * A God I Am:


 * AI Is a Crapshoot: Making an artifically intelligent control nanite worked just about as well as one would expect it.
 * Big Bad: Ben 10 and Generator Rex: Heroes United
 * Big Red Devil: Other than the mechnical form he first appears in, all his forms are quite demonic in appearance, getting even moreso as he transforms into more powerful forms.
 * Evil Counterpart: To Rex's Omega Nanite.
 * Healing Factor: So long as he has nanites to spare, the bodies he creates can regenerate nearly any damage in seconds.
 * Horror Hunger: Like Van Kleiss, he absorbs nanites from Evos to sustain himself. However, he reduces his victims to dust!
 * Implacable Man: No matter what you hit him with, he just keeps coming and can regenerate from nearly anything. The only way to truly stop him is to target and somehow hit the one tiny Nanite in his entire body that's actually him.
 * Machine Monotone
 * One-Winged Angel:
 * Person of Mass Destruction: Is outright stated to be capable of single-handedly destroying the world.
 * Psychopathic Manchild: Is rather child-like in his mannerisms and speech, speaking to his creator like a child seeking its parent's approval and guidence. He's also extremely dangerous and has no regard for life in any sense of the word. While he gradually gets more mature as he evolves, traits of the manchild part are still there, and he gets much more psychotic.
 * Sealed Evil in a Can: Was supposed to be imprisoned in an empty dimension where he couldn't do any damage, but it turned out it was the Null Void and he escaped.
 * Super Prototype: Of the Nanites; he's not called Alpha for nothing.
 * Sentient Phlebotinum: Is a sentient nanite. Any body he creates is normally composed of a swarm of absorbed nanites as well.
 * Technopath: Like Rex, he can manipulate machines by touch. The first body he shows up in was apparently a mechnical Null Void prisoner he merged with.
 * Voice of the Legion:
 * Voice of the Legion:
