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)

File:JadenYuki 4141.jpg

 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.

Season 4, post crossing the Despair Event Horizon:

File:Jadenseason4 2495.jpg


Johan Andersen (Jesse Anderson)

File:Jesse 3066.jpg

 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)



Sho Marufuji (Syrus Truesdale)

File:Syrus 9880.jpg

 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.



Tyranno Kenzan (Tyranno Hassleberry)

File:TyrannoHassleberry00 6953.jpg

  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.


Jun Manjoume (Chazz Princeton)

File:Chazz 7131.jpg

 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.



Asuka Tenjoin (Alexis Rhodes)

File:Alexis 1215.jpg

 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" (sorta) 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.


Other Students

File:Chum 6117.jpg

 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)



Daichi Misawa (Bastion Misawa)

File:Bastion 3318.jpg

 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)



Ryo Marufuji (Zane Truesdale)

File:ZaneTruesdale 275.jpg

 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.

Edo Phoenix (Aster Phoenix)

File:EdoPhoenix 2225.jpg

 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)



Rei Saotome (Blair Flannigan)

File:BlairFlannigan 4549.jpg

 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. Develops a major crush on Judai, to which he is predictably oblivious.

Voiced by: Eri Sendai (Japanese) and Lisa Ortiz (English)



Martin Kanou (Marcel Bonaparte)

File:300px-Martin 8100.jpg

 Ra Yellow. A friend of Rei's, who becomes the vessel for the Yubel after Cobra's fall. The son of Vice-Principal Napoeleon, he has major self-worth issues.

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.


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.


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.


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.


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.
