A list of characters from the Yu-Gi-Oh! GX anime and manga series, Oddly-Named Sequel 2: Electric Boogaloo to Yu-Gi-Oh!.

Main Characters

Judai Yuki (Jaden Yuki)

Osiris Red. The top student at Duel Academia and the series protagonist, whose character in Season 4 is practically unrecognizable from his character in Season 1, due to a brutal Break the Cutie arc in Season 3 and being used to demonstrate the realistic psychological trauma of many tropes from the original series and shonen anime heroes in general on a kid.

Voiced by: KENN (Japanese) and Matthew Charles (English)

Almighty Janitor: Is Osiris Red, the lowest tier that is mocked for being full of stereotypical losers, but is the best duelist in the academy.
Big Brother Mentor: To Sho and Kenzan.
Big Eater
Bi the Way: Blushed when close to a female duel monster, implied to like Johan (Yubel called him out on it. Twice.), and canonically loves Yubel, a hermaphroditic duel monster.
Book Dumb
Catch Phrase: "Gotcha!" in the original / "And That's Game!" in the dub..
- "Get Your Game On!" in the dub when starting a duel.
Chosen One
Chronic Hero Syndrome
Empathy Pet: Winged Kuriboh
Even the Guys Want Him
Expy: Yugi Mutou (in his role as the hero and his skill) and Katsuya Jounouchi (in his personality).
The Fool: To the point that Saiou uses the eponymous tarot card to represent Judai in his predictions.
Giving Someone the Pointer Finger: Always accompanied by his Catch Phrase.
The Hero
The Magic Poker Equation: There are real life duelists who would kill for the luck Jaden has, able to top deck the exact card he needs several times per duel. Shots of his hand often show a series of seemingly unrelated cards, then he'll draw the card he needs to put them all together in a combo. If he has no hand, he'll probably draw Bubbleman, Fifth Hope, Pot of Greed, or something that lets him draw more cards. Any time he ever plays A Hero Emerges his opponent will always pick the one card in his hand that would save him. And if he uses a card like Card Trooper to mill cards from his deck, every single time he does once of the milled cards is Necroshade or Necro Gardna.
Magnetic Hero: Ninety-five percent of the people he Duels end up as being his friends afterwards. Lampshaded in-universe.
Meaningful Name: Yuuki Juudai --> "a courageous teenager". ... No kidding.
Plot Armor: Thanks to the Magic Poker Equation. You could make a drinking game out of how many times Jaden goes against an opponent with a better deck and wins through sheer luck, but after Season 1 you'd need a liver transplant.
To Be a Master
Trademark Favorite Food: Fried shrimp.
True Companions: He seems to inadvertently make new friends without trying. Actually commented on in-universe.

Seasons 1-2:

The Ace
Blithe Spirit
Boring Invincible Hero
Cavalier Competitor
Chaste Hero: One must wonder how sheltered he must be from the world outside of dueling if he doesn't even know what 'fiancee' means...
Determinator
Idiot Hero
Indy Ploy
Keet
Kirk Summation
The Messiah
The Power of Friendship
"The Reason You Suck" Speech
Screw Destiny
Shonen Upgrade: His Neos Deck.
Strategy Schmategy: Ryou even manages to convince him his strength in dueling is his unpredictably.
Tiger Versus Dragon: The Dragon to Misawa's Tiger.
Warrior Therapist
Wide-Eyed Idealist
Wrong Genre Savvy: Make sure you realize what show you're in before you think of Duel Monsters as, "just a game."

Kaleidoscope Eyes (Mismatched Eyes)
Rage Against the Mentor: Played for laughs.
Silly Rabbit, Idealism Is for Kids
Split Personality
The Stoic

Johan Andersen (Jesse Anderson)

Introduced in Season 3; the top student of North Academia and owner of the only set of Gem Beast cards. He quickly becomes Judai's best friend and closest partner in the struggle to save reality in Season 4.

Voiced by: Kanako Irie (Japanese) and Christopher C. Adams (English)

Hey, It's That Voice!: His voice actress voiced Camula of the Seven Stars in the first season.
You Gotta Have Blue Hair

Sho Marufuji (Syrus Truesdale)

Judai's original best friend and Sidekick, a role he fights to keep in Season 2 but gradually leaves behind to pursue his own Character Development in Seasons 3 and 4.

Voiced by: Masami Suzuki (Japanese) and Wayne Grayson (English)

Juudai's best friend and sidekick, Sho Marufuji (U.S. name: Syrus Truesdale), whose feelings for his friend toe the line between brotherly and Ho Yay (if anything, this is exaggerated by several lines of dialogue in the dub, and has netted him rivals for Juudai's attention/affection in the form of Tyranno Kenzan and Overseas Champion Johan Andersen); he has unquestionably had the most Character Development of all the characters, symbolized by his promotion to a higher dorm every season.

Badass Adorable
Little Brother Instinct: Interestingly enough, exhibited towards Ryo in season 4, after Ryo becomes confined mainly to a wheelchair or hospital bed.
Blind Without'Em
Catch Phrase: In the dub, he has "Wait up!" and "Way to play, Jay!"
Color Coded for Your Convenience: His Character Development is accompanied by dorm promotions and changes of uniform from Red to Yellow to Blue.
Cute Machines: His Vehicroid monsters.
Dude in Distress: Frequently ends up as the hostage.
Dub Text: His relationship with Jaden
Fire-Forged Friends: With Kenzan.
Hidden Depths
The Lancer: Of the Best Friend variety.
Perverse Sexual Lust: Black Magician Girl and Thunder Nyan Nyan
Promotion to Parent: To an extent, towards Ryo in season 4. Revealed later in the Darkness arc that he really doesn't like it.
The Rival: To his older brother by the end, previously to Kenzan in Ho Yay Love Triangle over Judai.
The Short Guy with Glasses
Sidekick
The So-Called Coward
The Watcher : Actively tries to become one of these in season 3, after Judai's Heroic BSOD.
You Gotta Have Blue Hair

Tyranno Kenzan (Tyranno Hassleberry)

Ra Yellow. Enters Duel Academia in Season 2 and decides to become Sho's rival for the role of Judai's "little brother."

Voiced by: Hiroshi Shimozaki (Japanese) and David Wills (English)

Tyranno Kenzan (U.S. name: Tyranno Hassleberry), introduced in Season 2, a dinosaur-obsessed student with actual "dino DNA" flowing through his veins from an accident (and for some reason fancies himself a wannabe Army drill instructor in the dub). Originally fought with Sho over Juudai's attention (and affection), but quickly found a new rivalry with fellow fossil enthusiast Jim "Crocodile" Cook in Season 3.

Ambiguously Brown
Artistic License Biology: DINOSAUR DNA
Artistic License Medicine: He's injured his leg! Quick, let's replace it with the fossilized dinosaur bone he just dug up.
The Berserker: He blames it on dinosaur DNA.
The Big Guy
Defeat Means Friendship: Started out as a bully but became an ally when Judai defeated him.
Fire-Forged Friends: With Sho.
Hunk: Despite being 15 at the start of the series, he's quite handsome and already has a bodybuilder's physique likely as a result of digging for fossils.
Informed Ability: Said to be on the top of his class dueling-wise. He's won a single on-screen duel, however.
Kaleidoscope Eyes
Mr. Fanservice: He's handsome and muscular and his outfit makes sure you know it.
Muscles Are Meaningful: Zig zagged! In the world of Duel Monsters, Hassleberry's deck is the muscle he needs and usually relies on that for his battles, but when it comes to physical strength, he's capable of carrying an unconscious Edo, punched out a Duel Zombie, and swiped a blanket from Sho.
The Rival: With Sho in a Ho Yay Love Triangle over Judai.
Sleeves Are for Wimps: His outfit shows off his huge biceps.
Southern-Fried Private: He talked like one in the dub, but instead of being The Idiot From Osaka in the original, he punctuated sentences with the onomatopoeia for explosions.
Star-Crossed Lovers: Subverted with Alice. While he fell madly in love with her, she was unaware of his feelings and was possessed by the vengeful Doll Chimera spirit. When Judai exorcises the spirit from Alice in a duel, she returns to the spirit world herself as she was the spirit of a doll. This ensures the two could never be together.
Verbal Tic: Ends sentences with "-saurus!" and "-don!" in the original.

Jun Manjoume (Chazz Princeton)

Obelisk Blue/Slifer Red. Judai's first rival. Originally a rich snob who looked down on everyone else, he went on a short journey to find himself in Season 1 and came back much more honorable, despite his attempts to hide it, and determined to succeed because of his merits and skill rather than his money.

Voiced by: Taiki Matsuno (Japanese), Tony Solerno (English, Episode 1-89) and Marc Thompson (English, Episode 90 onwards)

The Rival and Worthy Opponent to Judai. Though initially a high-ranking member of Obelisk Blue, he experiences a losing streak and drops out, going on a journey to find himself and ending up at the North Academy duelling school. Though he rejoins Duel Academy, he is forced to start over at Slifer Red and decides to keep wearing his black North Academy uniform. He eventually makes it back up to Obelisk Blue.

He also has the power to see and hear monster spirits. Unfortunately, his "spirit partners" are the Ojama Trio, three rather disgusting and tactless monsters that frequently annoy him. He grows fond of them over time but will never admit it under any circumstance.

He gets significantly better treatment in the manga: Instead of the Ojamas, his spirit ally is the Light and Darkness Dragon, whose power even scares the Big Bad.

All Love Is Unrequited: Despite his massive (and often hilarious) crush on Asuka, the poor guy was doomed from the get-go.
Anti-Hero: Type III
Badass Longcoat
Badass Nickname: Manjoume Thunder!
Brainwashed and Crazy: Season 2
- Evil Costume Switch
- Light Is Not Good
- Rival Turned Evil
- The Dragon: To Saiou
Break the Haughty
Butt Monkey: After his character development, Manjoume tends to have absolutely horrendous luck.
Cain and Abel: With his older brothers
Catch Phrase
- Japanese version: "Ichi, jū, hyaku, sen, Manjōme-sandā!"
- English version: "Let's Chazz it up!"
Dark Is Not Evil
Empathy Pet: The Ojama Brothers
Expy: Seto Kaiba
Freudian Excuse
Good Is Not Nice
Great Detective: In his own mind, that is.
Impossible Hourglass Figure
Insistent Terminology: In the Japanese version, he insists that people show him respect by addressing him with the -san honorific: "Manjoume-san da" ("It's Mr. Manjoume"). This leads to his in-universe nickname of "Manjoume Thunder" when he transfers to a new school and his new classmates mistake "san da" for the Japanese pronunciation of "thunder".
Instant Awesome, Just Add Dragons: His Armed Dragons.
Instant Awesome, Just Add Mecha: His VWXYZ monsters in the anime.
Jerk Jock: Pre-Character Development, he was shaping up to be Judai's Draco Malfoy.
- Jerk with a Heart of Gold: Post-character development.
The Lancer: Of the Rival variety.
Lonely Rich Kid
Lost in Translation: His "Manjoume Thunder" nickname in the Japanese version- a nickname born from a Japanese wordplay pun- was replaced by "Let's Chazz it up!" and "The Chazz" in the dub. Unfortunately, this removes the explanation for why he starts using more lightning-based cards and symbolism after acquiring the nickname.
Love Makes You Crazy: His crush on Asuka
Noble Demon
"No Respect" Guy: Despite quite possibly being the second-best duelist at the academy, he sure doesn't get much respect.
Eerie Pale-Skinned Brunette
Parental Abandonment: True, this applies to 99% of the characters, but he's the only one with two older brothers who appear to be his guardians.
Plucky Comic Relief: Alternates between being this and being badass.
Punny Name: His nickname Manjoume Thunder ("sanda" in Japanese) is partly a pun on his Insistent Terminology.
The Rival
Screw the Money, I Have Rules: He eventually rejects his brothers' plans and tries to go pro without their connections.
Self-Made Man
Spell My Name with a "The": The dub has him called himself "The Chazz."
Third Person Person: The aforementioned "Manjuome san-da" can be translated as "It's the Manjoume" under some circumstances. The dub retains this, where he calls himself "The Chazz."
"Well Done, Son" Guy: Towards his older brothers in Season 1.
The Worf Effect

Asuka Tenjoin (Alexis Rhodes)

Obelisk Blue. Judai's designated female love interest (which, to her initial disappointment, comes to nothing) and the token shonen fanservice girl... which she hates. Kind, friendly, not-at-all proud or arrogant like most Obelisks, but has a predictably hard time in a series where she's surrounded by boys and Ho Yay.

Voiced by: Sanae Kobayashi (Japanese) and Priscilla Everett (English)

Asuka Tenjoin (U.S. name: Alexis Rhodes), the kind and pretty "Queen of Obelisk Blue" and Juudai's closest thing to a heterosexual love interest (as well as the Grace to Ryou Marufuji's Will). Also, Manjoume and just about every other boy in school has HUGE crushes on her (two have dueled Juudai out of sheer jealousy of her admiration for him), to the great delight of her older brother Fubuki... and to Asuka's own despair.

Action Girl: Ping-pongs between this and Faux Action Girl (particularly in Seasons 3 and 4). She's considered one of the seven best duelists in Duel Academy, but she merely wins against filler opponents and has a victory in a plot-important duel only twice. However, she manages to push her opponents pretty close to defeat before having the tables turned on her and is able to hold her own against the guys (Judai, Fubuki, and Manjoume), as well as battle people that gave the rest of the cast some issues (Titan, for example). The major question is if she lives up to her hype, which YMMV.
All Love Is Unrequited: Does not reciprocate Manjoume's crush on her, and Judai does not reciprocate her crush on him.
Blonde, Brunette, Redhead: With Those Two Guys, Momoe and Junko
Brainwashed and Crazy: Season 2, by Manjoume
- Evil Is Deathly Cold
- Evil Is Sexy
- Hypnotize the Princess: Saiou does this to her, making her even more Brainwashed and Crazy then prior.
- Mind Control Eyes
- Woman in White
The Chick
Dance Battler
Deadpan Snarker: When exasperated, particularly in the dub.
Hair of Gold
Hello, Nurse!: Something she's not happy about at all.
Idol Singer NOT!
Kill It with Ice: When brainwashed.
Male Gaze
Magic Skirt
Married to the Job: Cites being in love with dueling as one of her reasons for rejecting Manjoume's advances.
Ms. Fanservice: And quite self-aware about it, too!
Name's the Same: When partnered with Rei. Could also count as a possible Shout-Out to that series.
Only Sane Man
Platonic Life Partners: With Ryo.
The Smurfette Principle
So Beautiful It's a Curse: In the manga her introductory duel is actually motivated by her desire to be seen as a competent duelist and not just a pretty face. Judai seems to get this, which causes Asuka to fall for him pretty hard by the fourth season.
Well, Excuse Me, Princess!: Subverted. She hates being mistaken for a diva, and is really nice. She just gets really annoyed by some of Manjyoume's and Fubuki's more foolish antics.

Other Students

Hayato Maeda (Chumley Huffington)

Osiris Red. Judai's and Sho's roommate in Season 1 before graduating and leaving to work at Industrial Illusions.

Voiced by: Takehiro Hasu (Japanese) and Ted Lewis (English)

Animal Motifs: Koalas.
Big Eater: Ridiculously intensified by the dub.
The Big Guy
Hidden Depths: Mediocre duelist, highly talented artist. In his Crowning Moment of Awesome, he gets to use a card he himself designed.
Put on a Bus
Trademark Favorite Food: Grilled cheese sandwiches, though only in the dub.
"Well Done, Son" Guy

Daichi Misawa (Bastion Misawa)

Ra Yellow. The top student in Ra Yellow and smartest student at Duel Academia... at least before a disturbing romantic rendezvous in mid-Season 1; his shtick in Season 2 changed from being a genius to being forgotten by all the characters and ignored by the recruiting Cult.

Voiced by: Yuuki Masuda (Japanese) and Eric Stuart (English)

Awesomeness By Analysis: At first...
Badass Bookworm
Born in the Wrong Century: Would have fit right in among the geniuses of Yu-Gi-Oh! 5D's and received much more respect.
Brainwashed and Crazy
Butt Monkey: Season 2
Celibate Hero: Oooh, boy...
Crazy Prepared: Opponent tossed his deck into the lake? No problem—he's locked and loaded with 6 more decks to spare!
Deal with the Devil: Saiou promised Misawa that people would remember him and he would get the respect he deserved if he joined up. Pity it didn't actually work that way.
Demoted to Extra: Season 2 onward, and pointed out in the canon as his reason for joining the Society of Light.
Dude, Where's My Respect?: Cited as the reason for his Face Heel Turn and Heel Face Turn in season 2. By season 3 he's given up and chooses tostay in the different dimension.
Expospeak: Seems to be the sole reason for him to reemerge from the bus on occasion.
Fake Brit: In the dub.
Go Mad from the Revelation: He had a Freak-Out when he realized that he had a crush on White Magician Pikeru.
Hard Work Hardly Works
Huge Girl Tiny Guy: Misawa is taller and has a larger build than most of the main cast, and yet he's still dwarfed by Taniya, his eventual love interest.
Light Is Not Good
The Magic Poker Equation: Averted, and making him one of the few characters in the Yu-Gi-Oh! universe who doesn't rely on it. He uses mathematical formulas and science to fine-tune his decks to perfection, thereby minimizing the variable of luck in his duels and making his decks very precise and strategic. Unfortunately most of his opponents do rely on this trope and have Plot Armor to boot.
No Guy Wants an Amazon: At least, he thought he didn't...
"No Respect" Guy: Season 2
Number Two
Put on a Bus: Multiple times
The Rival
The Smart Guy
Tiger Versus Dragon: The Tiger to Judai's Dragon.
The Worf Effect: Beyond his one win against Manjoume, despite dueling impeccably, he never wins another duel... until he joins the Society of Light during Season 2...and even those wins are only against unnamed characters.

Ryo Marufuji (Zane Truesdale)

Obelisk Blue. Sho's older brother, nicknamed the Kaiser. Originally the top student at Duel Academia who prided himself on dueling with respect and honor, before a devastating loss to Edo Phoenix prompted an unexpected and long Face Heel Turn.

Voiced by: Takeshi Maeda (Japanese) and Scotty Ray (English)

Ryo Marufuji (U.S. name: Zane Truesdale), Sho's Aloof Big Brother, who goes by his nickname, the Kaiser; once the best of the best, he had a serious breakdown after losing a duel to Edo Phoenix.

Season 1:

The Ace: A variation. Described as "perfect" on multiple occasions, effortlessly defeats the main character in his first on-screen duel, and is the undefeated best duelist at the Academy. Only duels three times in the season (two of them against Judai) because they couldn't figure out how to make it dramatic anymore. Not quite charming, and definitely not hammy, but he fits the bill. Sets him up for a brutal Deconstruction in Season 2.
Aloof Big Brother
Always Someone Better: The first to defeat Judai, who probably counts as a form of Unknown Rival, and is barely disputed as superior (at least until the Graduation Duel).
- During the Phantom Demons arc, he easily destroys a villain without taking a single hit, before she forces him to make a Heroic Sacrifice for Sho. Judai very nearly loses against the same villain in the next episode.
Anti-Hero: Type II
Badass
- Badass Longcoat
- Badass Nickname: Kaiser
Big Brother Instinct
Bishonen
The Comically Serious
Deadpan Snarker: Heavy on the deadpan, and more so in the dub.
Expy: Seto Kaiba, predominantly the Aloof Older Brother aspect.
Good Is Not Nice
Heroic Sacrifice: For Sho in Turn 32
Lonely at the Top: Shows signs of this, not that he seems to mind.
The Magic Poker Equation: Hoo boy. Topdecks all of the cards he needs to bring out his ace monster, Cyber End Dragon, within 3 turns, tops. To be fair, his entire deck is based around summoning it, and real life decks can achieve similar results.
Married to the Job: A borderline example; similarly to Asuka, he states that he is devoted to dueling and uninterested in relationships. Of course, this was said to a middle school Fan Girl, so take that as you will.
Meaningful Name
Oblivious to Love: Extremely obvious in Turn 20.
Only Known by Their Nickname
Perpetual Frowner
Platonic Life Partners: With Asuka.
The Quiet One
Red Oni, Blue Oni: The blue to Fubuki's red.
The Rival: For Judai in the beginning; for Sho in the end.
Sadistic Choice: In episode 32, Camula gave him a choice between sacrificing Shou to win the duel, or standing down and losing his own soul and his Key. See Heroic Sacrifice.
The Stoic
- Not So Stoic: Has a few moments. Turn 20, in which Rei shows up with a massive crush, has a lot of moments.
  - And the end of the Graduation Duel, when he and Judai both stretch out on the floor, laughing their heads off.
Tall, Dark, Handsome and Snarky
You Gotta Have Blue Hair

Season 2:

Anti-Hero: Type V
Arrogant Kung Fu Guy
Badass Nickname: Now Hell Kaiser.
Badass Longcoat
Being Tortured Makes You Evil
Blood Knight: You know...with card games.
Broken Ace: So, so broken.
Break the Haughty

Combat Sadomasochist: Comes to enjoy the pain from the electric shock collar and dishing it out as well.
Dangerous Forbidden Technique: The Tail Deck of Cyber Dark monsters
Deceptive Disciple

Electric Torture: Although it originally drove his Freak-Out, he eventually grows to like it.
Evil Costume Switch
Evil Feels Good
Face Heel Turn
Fingerless Gloves: Wears a studded pair in the Pro League, pre-Freak-Out.
Freak-Out
The Gift: Deconstructed more brutally than with any other character besides maybe Judai.
Heir to the Dojo

Jerkass Dissonance
Kick the Dog: His duel with Sho.
Kick the Son of a Bitch: Firing Saruyama.
Limited Wardrobe: Still wears his school uniform after graduating (pre-Freak-Out).
Nietzsche Wannabe
Not Brainwashed: Just broken and batshit insane.
Shonen Upgrade: His Cyberdarks.
Shower of Angst
Slasher Smile: Countless times post-Freak-Out.
Too Kinky to Torture: Initially hates the electrodes; afterwards starts using them regularly for this reason, and also because he's just that screwed up.
Used to Be a Sweet Kid: Shown in Turn 83
Villain Protagonist

Season 3:

Anti-Hero: Type V --> Type IV
The Atoner: Arguably
The Berserker
Big Damn Heroes: Has a moment like this where he saves Sho and Ojama Yellow. Sets Sho up for a borderline Heroic Safe Mode.
Death Equals Redemption: Having found out that he's dying, he spends most of the season looking for one last great duel. However, he also repeatedly saves his brother's life, snaps Judai out of a Heroic BSOD with a Heroic Sacrifice, and is generally loses most of the harsh, psychotic persona of season 2.
Death Is Dramatic: He kicks Judai's pathetic whining ass back into gear about five seconds before he dies.
Dying Moment of Awesome: He quadruples the attack points of his greatest monster, and despite his losing the duel, snaps Judai out of his Heroic BSOD, something that three other Heroic Sacrifices had failed to do previously.
Good Is Not Nice
Heroic Sacrifice: against Yubel.
Secretly Dying: Until it becomes impossible to hide, he tells no one of his heart condition and brushes off any kind of concern from those who do notice the pain he's in.
Spirited Competitor: He spends almost the entire season looking for someone strong enough to give him one last amazing duel.
This Is Your Brain on Evil, Up to Eleven

Season 4:

Back from the Dead
Contractual Immortality: Though it's unclear whether or not this is something he wants.
Doing In the Scientist: His heart problems weren't due to dueling with electro-shock collars but the dangerous forbidden deck he used.
Heel Face Revolving Door: Comes to his senses and gives up the Hell Kaiser persona thanks to Sho.
Ill Boy
Unexplained Recovery: In contrast to the explained revivals of the other characters, he just randomly shows up. In his case, he literally has heart failure before fading away, whereas the others simply fade away, but were really trapped in another dimension.

Fubuki Tenjoin (Atticus Rhodes)

Obelisk Blue. Asuka's older brother and Kaiser's best friend, missing for the first half of Season 1 and brought back a dangerous mystery that would not be solved until Season 4.

Voiced by: Koji Yusa (Japanese) and Jason Anthony Griffith (English)

Back for the Dead: He suddenly emerges from the bus for a few episodes seemingly for the sole purpose of having another character to kill off to send Judai over the Despair Event Horizon.
Big Brother Mentor: For Manjoume
Badass in Distress: Becomes this one in episode 159 where Yusuke put a gas on him which made him unconscious and Axel has to rescue and hospitalized him
Brainwashed and Crazy
Bishonen
Chekhov MIA:Though mention often by Asuka and Royo he doesn't appear physically until epsiode 28
Chick Magnet
Cloudcuckoolander
Crouching Moron, Hidden Badass: Beneath his carefree, goofy exterior lies one of the best duelists in the school.
Disney Death:In Season 3, he is killed when he is sacrificed for Brron's ritual, but is revealed to being held in another dimension by Yubel and is returned to Duel Academy at the end of the season.
Enemy Within: Darkness
Evil Is Not a Toy
The Ghost:until episode 29
Informed Ability: He's considered to be one of the best duelists at Duel Academy. Despite this, he never wins a single duel on-screen. Though to be fair, two of his opponents were Judai and Hell Kaiser Ryo, and it's implied that he wasn't playing seriously in his duel against Asuka.
Mask of Power: Darkness
The Matchmaker: For Asuka, despite her protests.
Put on a Bus: Multiple times, with one return offering no explanation as to where he even was.
Red Eyes, Take Warning: Darkness is associated with Red Eyes Darkness Dragon.
Red Oni, Blue Oni: The red to Ryo's blue.
Shipper on Deck:: Supports Manjoume's attempts to win over Asuka. Which tend to fail spectacularly. He also supports Asuka being with Judai or Ryo. Really, he just wants her to end up with somebody.
Sympathy for the Devil:In his duel with Yusuke. He didn't care about what Yusuke was doing, he was just glad he was alive, calling him his friend and apologized that he didn't save him the first time.
Targeted Human Sacrifice:Becomes a sacrifice in the 3rd season to Brron's ritual to complete the Super Polymerization card that required several negative emotions to create. Atticus providing the negative emotion of anguish.
That Makes Me Feel Anguish: In the 3rd season his negative feeling of anguish becomes a key sacrifice to Brron's ritual for the creation of the Super Polymerization card. Atticus expresses his anguish to Jaden before he is sacrificed stating his feelings of helplessness being sacrificed.
Tall,Dark Handsome and Snarky: He is very tall and handsome
Totally Radical: In the dub, even when under the influence of Darkness.

Edo Phoenix (Aster Phoenix)

Judai's new rival in Season 2. By day, he's the top duelist in the Pro League and the unfortunate dupe of his manager and best friend Saiou in recruiting members for the Society of Light Cult; by night, he prowls dark alleys dressed up as Duel Monsters, defeating criminals in an attempt to find the man who killed his father.

Voiced by: Akira Ishida (Japanese) and Pete Zarustica (English)

Anti-Hero: Type III
Badass
The Dulcinea Effect: For Amon's girlfriend Ekou in Season 3. This even confuses him, not just the viewers.
Expy: Seto Kaiba
Fire-Forged Friends: With Judai, though the latter would have you believe they were friends earlier than that.
- Also with Ryo in Season 3.
Grumpy Bear
Heroic Sacrifice: See The Dulcinea Effect.
Jerkass: He wouldn't be a Kaiba expy if he weren't, though he's arguably worse than Kaiba in some ways.
- Jerk with a Heart of Gold: During Season 3, he becomes this.
Missed the Call: Nope, you're not The Hero, nor The Chosen One...nor The Only One Allowed to Defeat You!
Oedipus Complex: With his adopted father, DD.
Orphan's Plot Trinket: The Destiny Hero cards
"The Reason You Suck" Speech: In his first duel with Judai.
Refuge in Audacity: Mocks Ryou's Cyber Dragons, yet accuses Judai of not showing proper respect to his Destiny Heroes when the latter shows how amazed he is by them.
The Rival
Totally Radical: His speech in the dub tends to follow this pattern.
Shoot the Dog
Spell My Name with an "S": Is it Edo, or Ed? Most people go with Edo, although some would argue that Edo is a botched translation and it really means Ed anyway.
- Then again, some people bring up the Stealth Pun in his name; Phoenixes were very popular in artistic depictions of the Edo period.
Tall, Dark and Snarky
Tsundere: Male version and probably non-romantic; type B example towards Saiou and type A towards Ryo in season 3.
Well-Intentioned Extremist

Rei Saotome (Blair Flannigan)

Osiris Red. Initially a one-shot character with a crush on Kaiser, she returns at the end of season two and earns her way into the academy by becoming runner-up in the Genex Tournament, despite still being too young to enter the academy the normal way.

Winner of Miss Duel Academy two years in a row, she finds herself in a tie with Asuka in her third year.

Alpha Bitch
Green-Eyed Monster: To Asuka, who didn't want the title of Miss Academia (unlike her, who would have claimed the title three years running), but got it anyway.

Oblivious to Love: The only one besides Asuka not to notice Misawa's crush.
Theme Naming: His Cyber monsters are named for stars in the constellation Draco.

Fubuki Tenjoin (Atticus Rhodes)

Adaptational Badass: He goes from comic relief in the anime to beating Judai in the manga.
- This is hinted at much earlier when a flashback shows the end result of what we're led to believe was a complete Curb Stomp Battle with David Rabb biting the proverbial curb. Remember that Rabb is one of the Co-Dragons who gave Manjoume a rough time when they dueled.
Blow You Away: Runs a WIND Winged-Beast Sphere Deck.
Badass Nickname: Fubuking. Asuka doesn't like it, though (or its less badass English counterpart, "Rhodie".)

Demonic Possession: Falls victim to this, just like half of the rest of the cast.

Time to Unlock More True Potential: His Sealed Beasts depend on the Sealed Mantra Spell to activate their effects, without it they're essentially Normal Monsters.
Took a Level In Kindness: Compared to his anime self.

Johan Anderson (Jesse Anderson)

Beetle Maniac: And the rest of the Insecta Class, apparently.
Bug Catching: Apparently his main pastime.
Cloudcuckoolander: "Hey, did you see a butterfly go through here?"
Demoted to Extra: No Gem Beast cards, no Ho Yay with Judai, just one instance of possession and a lot of bug chasing.

Amateur Sleuth: Attempting to find the source of the Shadow Duels, and actually does a decent job before...
Demonic Possession: The real reason he was sent to Duel Academy, just like every other American!
Laser-Guided Amnesia: Tragoedia covers his tracks well.
Meaningful Name: His Legendary Planet is Mars, and his monsters all have military-themed names (Electro Sergeant, Division etc). Mars was the Roman God of War.
Shock and Awe: What his Deck theme seems to be at first due to his Machines having names like 'Electro Sergeant'.

Edo Phoenix (Aster Phoenix)

Evil Counterpart: The Grand JUPITER to Judai's The EARTH.
Tyke Bomb: Tragoedia claims to have raised him for this purpose.
Unwitting Pawn: Just like his anime counterpart with Saiou and DD, has no clue that his adoptive father and mentor is Tragoedia's puppet, or that he's giving people over to Tragoedia.

Cards

Elemental Heroes

Judai's core deck theme revolving around low-level monsters based on comic book superheroes, they can fuse together and use support cards to perform powerful combos.

Barbarian Hero: Wildheart.
Bat Signal: Hero Signal.
Elemental Powers: The base heroes all conform to one of the common elements: Avian, Sparkman, Burstinatrix, Clayman, Bubbleman, Necroshade, Blade-Edge, and eventually Neos. Then in the manga we get Plant-based Heroes like Knospe and Woodsman.
Fusion Dance: Their key strength, almost any two heroes can fuse together, so Judai always has plenty of options when it's time to fuse.
Gatling Good: Rampart Blaster
Light'Em Up: Shining Flame Wingman, Electrum, and Neos and some of its fused forms.
Magikarp Power: Without their support cards or Fusion cards the individual heroes are pretty weak. But once you get the cards you need for a combo or a Fusion, watch out.
Power Gives You Wings: Flame Wingman and Shining Flare Wingman.

Neo Spacians

An archetype based on cards Judai designed as a child, they were sent into space on a time capsule and infused with cosmic energy. They consist of the six base Neo-Spacians, Elemental Hero Neos, and some other non Neo-Spacian cards that still fit the general theme/idea, like Rallis the Star Bird.

Bat Signal: N-Signal
Dark Is Not Evil: Dark Panther.
Elemental Powers: One Neo-Spacian for each of the game's six Attributes: Flare Scarab, Grand Mole, Aqua Dolphin, Air Hummingbird, Dark Panther, and Glow Moss.
Energy Beings: Glow Moss
Fusion Dance: Contact Fusion, a unique method of fusing not needing a Fusion-type card to initiate.
Sapient Cetaceans: Aqua Dolphin.
Spotlight-Stealing Squad: Once Judai picks them up in Season 2 most of his victories in the rest of the series come about due to a Neo-Spacian, Neos, or some fusion of the two.
This Is a Drill: Grand Mole.
Yin-Yang Bomb: Chaos Neos

Cyber Dragons/Cyberdark Dragons

Ryo's key deck theme, he uses the Cyber Dragons in Season 1, prefers the new Cyberdarks in Season 2, and in Seasons 3 and 4 utilizes both with deadly efficiency.

Animal Mecha
Breath Weapon: Cyber Dragon's attack, Evolution Burst
Dark Is Evil/Light Is Good: Ryo is a good guy when using Cyber Dragon, but following his Face Heel Turn he uses the Cyberdarks to fit his new persona
- Dark Is Not Evil: Once he turns back to good he still uses the Cyberdarks. However, the only usage he makes of the Cyber Dragons while evil is as fodder to power up the Cyberdarks, so Light Is Not Good is mostly averted.
Dragons Up the Yin-Yang: Played straight as can be with the Cyber Dragons and Cyberdarks representing the two halves of the symbol.
Evil Counterpart: The Cyberdarks to the Cyber Dragons.
Expy: Ryo's status as an Expy of Kaiba is hard to dispute when Cyber End Dragon looks like a combination of Blue-Eyes Ultimate Dragon and Blue-Eyes Shining Dragon. By the same token, Cyberdark Dragon could be considered an Expy of Red-Eyes Black Dragon.
Fusion Dance
Instant Awesome, Just Add Dragons
One-Hit Kill: Ryo uses Chimeratech Overdragon to perform one, signaling his Face Heel Turn. Dedicated real life decks using Cyber Dragon and its variants can also pull these off.
Our Dragons Are Different
Power Trio: The Cyberdarks

Ojamas

Manjoume's spirit partners, to his disgust. Although he never stops insulting them, they become a key part of his deck as he adds more support cards for them over the course of the series.

Combination Attack: Ojama Delta Hurricane
Fusion Dance: Ojama King
Knight in Shining Armor: Ojama Knight
Meaningful Name: "Ojamashimasu" is a Japanese phrase roughly translating as "pardon me for interrupting/intruding". It's why the flavor text on the card mentions the Ojamas always butt in on things, and why their stronger cards fill up the opponent's Monster Zones.
Plucky Comic Relief
Shout-Out: Their mannerisms in the dub are based on the Three Stooges.
Stone Wall: Ojama King has 3000 defense, and Ojama Knight trails just after it with 2500.
Underwear of Power

Destiny Heroes

Edo's main monster themes, based on characters in British literature.

Bat Signal: Destiny Signal
Dark Is Not Evil
Evil Counterpart: To the Elemental Heroes, naturally.
Shout-Out: Many to English literature, such as Double Dude being based on Jekyll and Hyde.
Time Master: Their effects revolve around time control, with effects relying on doing things on later turns. For example, Diamond Dude lets you discard the top card of your deck, and if it's a Spell you can activate its effect on your next turn.

Phantom Demons (Sacred Beasts)

Three powerful and dangerous cards sealed under Duel Academy - Uria, Lord of Searing Flames; Hamon, Lord of Striking Thunder; and Raviel, Lord of Phantasms.

Awesome but Impractical: At least with the God Cards, getting three monsters onto the field was fairly feasible. But good luck summoning these guys, whose summon requirements are to tribute three Continuous Traps, three Continuous Spells, and three Fiend-type Monsters.
- Awesome but Practical: On the other hand, if you set up your deck specifically around them (for example, if you run a pure Fiend Deck for Raviel)...
Cards Of Mass Destruction: Once in play they begin to drain other cards of their energy.
Dem Bones: The three all bear skeletal features, Hamon being the most prominent.
Dub Name Change: Completely reversing the intent for them to be evil versions of the God Cards by calling them "Sacred Beasts".
Evil Counterpart: Of the Egyptian God Cards in the original series.
Large and In Charge
More Teeth Than the Osmond Family
Nested Mouths: Uria
Playing with Fire: Uria's attack.
Shock and Awe: Hamon's attack.
Spikes of Villainy
