List of Yu-Gi-Oh! GX characters

; : :The main protagonist of the series. An energetic, passionate and optimistic boy who comes to Duel Academy to learn to become the new King of Games, he is a talented duelist who beats some of the toughest duelists, including Professor Crowler and Chazz Princeton/Jun Manjoume. Despite his excellence in dueling, he is placed in the Slifer Red dormitory due to his below average grades and general disinterest in anything that is not duel-related. : :In the first season, Jaden's excellence in dueling leads him to become one of the Spirit Key holders, a responsibility given to the best duelists in the school to guard the Spirit Keys from the Shadow Riders who seek to resurrect the Sacred Beasts. In the second season, Jaden fights against the Society of Light, a cult like organization that seeks to brainwash the world, and is revealed to possess Gentle Darkness, a power that was created to balance out the light. The Gentle Darkness also gives Jaden special powers such as the ability to communicate with Duel Spirits, most often with Winged Kuriboh, a card he received from Yugi Muto on the day of his entrance exam. In the third season, Jaden and his friends are transported to an alternate dimension where duel monsters are real. While there, Jaden falls into despair after seeing his friends sacrificed and becomes possessed by the Supreme King, a ruthless and merciless ruler and the original wielder of the Gentle Darkness. After being released from his possession, Jaden learns that he is the reincarnation of the Supreme King and that Yubel, a duel Monster that was the Supreme King's guardian and the mastermind behind the alternate dimension, is bound to the Supreme King by prophecy. In order to fulfill the prophecy and cleanse Yubel of her corruption caused by the light, Jaden decides to fuse himself with Yubel, gaining the powers of both the Supreme King and Yubel and possessing the ability to bring duel monsters to life, see visions of the future, resist supernatural powers such as hypnosis, and generate wind. He is described as someone who is "not human." Afterwards, Jaden's original happy and easygoing personality turns serious and aloof, as he no longer finds dueling fun and wishes to only duel when he needs to, and finds himself trying to distance himself from others after bearing guilt for the misfortunes his friends and others endured. In the fourth season, Jaden battles against Nightshroud, who preys on people's negative emotions and wishes to engulf humanity into his Darkness Realm, and begins to return to his old personality with the help of his friends and Yugi Mutou, who he gets to duel. : :He specializes in using Fusion Monsters, his main deck being the Elemental Heroes, monsters based on comic superheroes with his signature being "Elemental Hero Flame Wingman." Jaden later switches decks to a "Neo-Spacian"-based one, monsters based on alien creatures drawn by Jaden when he was younger which use contact fusion, fusion without the need of a fusion card, to fuse "Elemental Hero Neos", his new signature card, and create a new Fusion monster. He later combines the two decks together. ; : :Jaden's roommate and friend at Duel Academy.

He is good friends with Jaden despite their very different personalities and is seen to view Jaden as a worthy rival. Bastion's decks are all based around a single attribute and usually contain monsters, spells, and traps related to Science or Math such as "Water Dragon" or "Magnet Warrior". ; : :A freshman duelist who ranks in the Obelisk Blue and one of Jaden's rivals. He is elitist, thinking that low-scoring duelists such as Jaden should be kicked out. It is revealed early in the first season that his elitism stems from his older brothers, who rule over the political and financial worlds and urge him to become a great duelist in order to have their family reign over the dueling world. After becoming estranged with his brothers, Chazz decides to pursue a career in dueling without their help. Initially hating Jaden, he comes to respect and befriend Jaden, seeing him as his rival, and develops a crush on Alexis (Asuka). He initially uses a power based deck, focusing on powerful monsters such as the Armed Dragons.

He later combines all the decks together to make his final and permanent deck. ; : :A beautiful and talented duelist who is regarded as the queen of the Obelisk Blue, but unlike many of the other Blue members, is not elitist and quickly takes interest in Jaden. She does not follow the crowd or regard herself as better than other people like some students in the dormitory, but has a stern pride as an Obelisk Blue duelist. Alexis is shown to be good friends with Zane Trusdale, as he was close friends with her brother Atticus until his disappearance and helped her search for clues surrounding his disappearance, until it is revealed that he joined the Shadow Riders under the control of Nightshroud.

Since he is the top duelist, he was given the honor of choosing his partner in the graduation duel. He chooses Jaden and passes the title of top duelist to Jaden before leaving Duel Academy and joining the Pro-Dueling League. Originally a star in the Pro-Dueling League, he loses a duel against Aster Phoenix and slowly loses his winning streak and reputation. Looking for a chance to redeem himself, he begins dueling underground, which uses shock collars to punish losses, and develops a more aggressive and violent personality earning him the name "Hell Kaiser" in the Japanese version. While in the alternate dimension, Zane teams up with Aster to stop Yubel, but in his final battle, his heart gives out due to the shock collar, with his final wish being to let the Cyber End Dragon be his symbol and for Jaden to overcome his darkness. He is later revealed to have survived, but is in a weakened state. He uses a Cyber Dragon deck which consists primarily of different Cyber Dragons, with his signature being "Cyber End Dragon." He later acquires the Cyberdark deck to reflect his new personality, with his signature being "Cyberdark Dragon." He later combines these two decks, with Cyber End Dragon becoming his signature once again. ; : :First appearing in "The Maiden in Love", Blair Flannigan is a young girl who enrolls into Duel Academy disguised as a boy in hopes of getting close to Zane Truesdale, her crush. After being caught by Jaden while sneaking into Zane's dorm room, he defeats her in a duel and confesses her love to Zane, but is politely rejected due to her being in fifth grade.

However, the capsule was instead affected by the Light of Destruction, driving her insane and causing her to begin to believe that love and suffering are the same thing. Upon returning to Earth, Yubel was heavily damaged to the point where her hand was the only thing left of her. Yubel met Professor Viper and made a deal with him that if he could gather enough energy to revive her and make Jaden pay, she would revive his dead son. Once Viper failed, Yubel presumably killed Viper, although his status is unclear in the English dub (in the Japanese version, she rewrites his memories to send him to walk to his death). Yubel would possess Marcel's body and then Jesse Anderson's body to show Jaden how much she loves him through the pain her actions bring to him.

Under Yubel's control, Marcel played an Exodia deck and, after gaining the Three Sacred Beast cards, switched to a new deck that focuses on them. In the English dub, Marcel has a French accent. When he is possessed by Yubel, he loses this accent, leading to a running gag where whenever someone talks to him they ask what happened to his accent. ; : :Professor Thelonious Viper was a major antagonist. During a mission with his comrades, he found an abandoned baby, only for his comrades to go in another direction and ne killed by a bomb. Believing the baby saved his life, Viper named the boy Pierce and adopted him, giving Pierce a deck of Duel Monster cards as a present. However, the cards were blown away by the wind, and Pierce was killed after being hit by an oncoming truck while going after them. In another mission, Viper encountered Yubel, who offered to resurrect Pierce if Viper were to gather energy to revive it and make Jaden pay, to which Viper agreed. Several years later, Viper entered Duel Academy and gave Bio-Bands to the students of the academy, hoping that the energy they produced from their duels would be enough to revive Yubel. Viper would eventually duel Jaden Yuki and lose to him, but the energy from the duel revives Yubel. However, Yubel found another way to keep her deal to Viper. She cast Viper in an illusion and made him believe his son never died. Viper walked off the arena that he and Jaden were dueling on and fell to his death; in the dub, his status is most likely dead but unclear.
