Main Characters

    Judai Yuki (Jaden Yuki) 
  • Big Brother Mentor: To Sho.
  • Break the Cutie: Not nearly as much as in the anime, but it's hard on him watching his mentor go into a coma, and he briefly falls into a Heroic BSoD during his duel with Reggie, as he knows that the loser will suffer a penalty game.
  • Defeating the Undefeatable: Judai and Manjoume do this to each other.
  • Defeat Means Friendship: Some things never change. It even sticks after Manjoume beats him right back.
  • Early Installment Weirdness: In the first chapter he uses some Elemental Heroes he used in the anime such as Wildheart, Sparkman and Bubbleman. In later chapters he never uses them again in favor of newer Elemental Heroes which will be more well-known to Manga!Judai.
  • 11th-Hour Superpower: During the final turn of the Duel with Tragoedia, he summons Ma'at herself to end it by fusing Winged Kuriboh with Light and Darkness Dragon.
  • Friendly Rivalry: With Manjoume. Infinitely more friendly than in the anime.
  • Let's Get Dangerous!: Quick to do this once people are in trouble/danger, be it Sho's threatened expulsion or Duels of Darkness.
  • Offscreen Moment of Awesome: Like in the anime, he defeats Chronos as part of his entrance exam, but while this is brought up, it's never shown, and Ryuga serves as Judai's Warm-Up Boss.
  • "The Reason You Suck" Speech: Gives one to Ryuga, who forces the students he defeats to give him their cards.
  • Sadistic Choice: Chronos forces him to duel Sho. If he wins, Sho will be expelled, and if he loses, his deck will be confiscated. He decides to win, and it turns out that Sho's 0 on the last test, the reason he was in trouble, was not his final grade.
  • School Uniforms Are the New Black: His professional attire, to Misawa's chagrin. And yes, he stayed Slifer Red.
  • Sentai: Masked Heroes.
  • To Be a Master: Aspires to duel professionally like his mentor, Koyo Hibiki.
  • You Monster!: Along with Manjoume, against Tragoedia.

    Jun Manjoume (Chazz Princeton) 

    Daichi Misawa (Bastion Misawa) 

    Asuka Tenjoin (Alexis Rhodes) 

    Sho Marufuji (Syrus Truesdale) 
  • Adaptational Badass: Admittedly starts out as weak as before, but toughens up much more quickly this time around. His mistake that caused Ryo to lose faith in him was not misusing a card, but throwing a game to spare the feelings of his opponent. Subverted somewhat though, as (unlike his anime counterpart) the only duel he ever wins in the manga is the tag duel with Manjoume, every other duel he loses.
  • Big Brother Worship: Has a bit of a case of this toward Ryo, as while the other spectators are rooting for Manjoume, he is completely convinced that Ryo will win. And he turns out to be correct.
  • Cute Machines: Still plays Vehicroids, but uses entirely different ones.
  • Combining Mecha: Armorroid, the Solidroids and Barbaroid.
  • I Let You Win: Throws a duel when he was younger in order to spare the feelings of his opponent, who was on the verge of tears after he had destroyed one of his better monsters.
  • Power Armor: He has a card that enables him to thwart direct attacks, but if it gets taken off, he takes all the damage that was prevented.
  • Took a Level in Badass: To the point that Manjoume can soon count on him in a partner duel.
  • "Well Done, Son!" Guy: Wants to be acknowledged by his brother, and eventually, he is.
  • Worf Had the Flu: He lost against Ryuga because of Ryuga's cheating.


A new teacher at Duel Academy, who must defeat 50 students to qualify. He plans on using his position to turn the dueling world over to his ideals, but Judai defeats him.
  • Warm-Up Boss: He's not particularly skilled at dueling, and wins by cheating.

    Midori Hibiki 
Koyo's older sister and a professor at Duel Academy Japan.
  • Badass Teacher: Is about to win against Reggie until Reggie indicates that if she does, she won't get the information on Koyo's coma
  • Cool Big Sis: To Koyo by blood and to Judai by choice.
  • Stern Teacher: Doesn't hesitate to go hard on Judai, although typically does so in a cheerful manner.
  • Worf Had the Flu: She gives up a chance to win in order to try to help Koyo. By the time she's committed herself to finishing Reggie off to protect Judai, it's too late

    Emi Ayukawa 
  • Agent Scully: There must be a logical explanation for multiple people falling unconscious after dueling today, just like at the Battle City Tournament. There's no way it's evil sorcery like the records claim.

Duel Spirits

    Winged Kuriboh 
  • Big Damn Heroes: After Judai loses to Tragoedia when the latter is possessing Fubuki, Kuriboh saves him from the penalty game. He does it again with Light and Darkness Dragon after Tragoedia's defeat, sealing him permanently.
  • Heroic Sacrifice: With Light and Darkness Dragon to seal Tragoedia for good.
  • Pokémon Speak: Usually communicates with "kuri kuri".

    Light And Darkness Dragon 
  • Buried Alive: Because Manjoume wanted to prove that he could duel alone. Quickly rectified, after he loses to Judai.
  • The Dreaded: The Big Bad has an understandable Freak Out! when seeing L and D as a Spirit Card holding the Feather of Ma'at.
  • Expy: To Blue-Eyes White Dragon and Red-Eyes Black Dragon.
  • Heroic Sacrifice: Alongside Winged Kuriboh, to permanently seal Tragoedia.
  • Instant Awesome: Just Add Dragons!: Manjoume's ace in a deck full of them.
  • Undying Loyalty: To Manjoume, watching his duel with Judai, even after said owner pitched a tantrum and buried him so that Manjoume could try proving that he could duel on his own. Naturally, Manjoume came back.
  • The Voiceless: Actions speak well enough when you're a Dragon Spirit.
  • Yin-Yang Bomb: The name says it all. Notably, the real-life version of the card counts as both LIGHT and DARK attributes while on the field.

Other Duel Academy students

    Seika Kohinata 
Winner of Miss Duel Academy two years in a row, she finds herself in a tie with Asuka in her third year as a result of Judai abstaining.
  • Animal Motifs: Snakes.
  • Dirty Coward: When she learns the student who hasn't voted yet is an Osiris Red, she challenges him to a duel under the belief it'll be easy to defeat him. If she wins, he votes for her. Is she loses, he votes for Asuka. Once she learns the boy is the very same Osiris Red student who defeated Professor Chronos, she backs out and gets him to duel Asuka. She never thinks about dueling Asuka herself with Judai's vote as the prize.
  • 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.
  • Let's Get Dangerous!: Once motivated to duel, she reveals a wicked Snake Deck. She still loses to Judai, though.
  • Pyrrhic Victory: She technically wins the title as a result of Judai and Asuka's duel, but concedes it, saying no one would acknowledge her.
  • Serious Business: Her view on Miss Duel Academy. Judai and Asuka's indifference infuriates her.

    Ryo Marufuji (Zane Truesdale)

    David Rabb 
The other Duelist from Duel Academy America and is also possessed by Tragodeia and after the Duel Spirits.
  • Heroic Build: Subverted. Definitely has one, except he's not heroic.
  • Hoist by Their Own Petard: Calls a Shadow Game against Manjoume. Loses.
  • Jerkass: Jim calls him a jerk in passing, and wants to fight Fubuki because he defeated the person he wanted to defeat.
  • One Turn Kill: Against Asuka.
  • Put on a Bus: After his loss to Jun, he suffers the side effects of the Shadow Duel and is left comatose for the remainder of the series, only waking up once Judai and Jun defeat Tragoedia.
  • To the Pain: Rants on about how he enjoys pain in his duel with Manjoume.

  • 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.

Big Bad

The Big Bad of the Manga, an Ancient Egyptian manifestation of a man whose village was slaughtered to create the Millennium Items.
  • Achilles' Heel: The Feather of Ma'at, until he gets to full power when he duels.
  • Big Bad: Of the GX manga.
  • Body Surf: Since he lacks a physical body he needs to possess other duelists to duel and in order to survive he tends to switch his possession from person.
  • Demonic Possession: He can posses other peoples bodies and looks very demonic.
  • Eldritch Abomination: Think Diabound, but far, far worse. You might be getting close to Tragoedia.
  • Energy Absorption: The Planet Series cards he distributes to the American students sap small amounts of energy from Duelists to aide in his resurrection.
  • Expy: Of Dark Bakura and Zorc Necrophades from Yu-Gi-Oh!.
  • For the Evulz: He claims at one point that he has no goal, he's simply bored.
  • Karmic Death: He got killed by a fusion of the very Duel Spirit that corrupted him.
  • Light Is Not Good: He has The Sun as his planet card.
  • Meaningful Name: "Tragoedia" is Greek for "Tragedy".
  • The Man Behind the Man: And he impressively maintains this up until the end of the story.
  • The Power of the Sun: The Supremacy SUN, though it combines it with Casting a Shadow due to being a DARK Fiend-Type and having a solar eclipse in the card art.
  • Sealed Evil in a Can: And he was so powerful that he wasn't even completely sealed in his tablet. Played straight with his heart, though.
  • Sinister Silhouettes: In his early appearances possessing the principal's body, and from the crystals he gives to some of his subordinates.

Other characters

A professional duelist and World Champion who serves as both Judai's and Manjoume's inspiration and gave both of them their spirit cards. Is in a coma after losing a shadow game.

How well does it match the trope?
