The spirit of an ancient Pharaoh, Atemu lives within the Millennium Puzzle. He has no physical form of his own, and therefore must share one with Yugi. If Atemu wishes to take over Yugi's body, the body will morph to look more like him. During the ceremonial battle, the egyptian gods give Atemu a body of his own which he uses to face Yugi.

SEIYUU: Kenjiro Tsuda

Kaiba is considered to be the most powerful duelist in the world. He is undefeated in a duel except for one defeat by Yugi Muto. Kaiba doesn't exactly hate Yugi, but he doesn't consider him a friend and doesn't believe in the power of Yugi's Millenium Puzzle. He posseses three Blue-Eyes White Dragons, which is amazing when you consider that there are only four in the world! He duels for his brother Mokuba, who always looks up to him.

Ryou Bakura would probably never have even entered into the scene, were it not for an odd compulsion that drives him to seek out the Millennium Items. He's drawn to the Duelist Kingdom from the combined influence of Pegasus' Millennium Eye and Yugi's Millennium Puzzle. His Millennium Ring houses an evil spirit of the Thief King Bakura, the Pharaoh's arch enemy from the ancient past.

5000 years ago, give or take a day, an evil beast known as Zorc, creator of the Shadow Realm rampaged throughout Egypt. The Pharaoh sealed him away into the shadows from whence he came, but Zorc still had one more trick up his sleeve. He found himself a lonely tomb robber named Bakura and imprisoned a small piece of his soul within him, and the rest was trapped forever within the Millennium Items. The lonely tomb robber became known as many things, mainly Thief King Bakura (or my personal favorite: Bakura, Tomb Raider), and has one mission - to retrieve the Millennium Items, return to the ancient past, transform back into Zorc, and try again!

VOICE ACTOR: Bella Hudson
SEIYUU: Terada Heruhi

When we first encounter Mai Valentine, she's a conceited, laugh-your-head-off duelist who's out for number one: herself.

We last see her give a goodbye hug to Yugi as he departs from America, and a final humorous scene of Tea's jealousy being shown as she breaks up the hug Rebecca gives to Yugi.

YU-GI-OH! GX

NAME: Jaden Yuki
JAPANESE NAME: Yuki Judai
AGE: 15 at debut, currently 17
STATUS: Third year student
DORM: Slifer Red
RELATIONS: None
VOICE ACTOR: Matthew Charles
SEIYUU: KENN
DEBUT: Episode 1 - The Next King of Games

SEASON 1
15-year old Jaden joins the Duel Academy - a school established by Seto Kaiba sometime after the events of the Duel Monsters season. While on his way to the entrance duel, he runs into his idol, Yugi Muto, who, in the ten years since we last saw the character, has become a worldwide celebrity and duelist sensation. Jaden receives from Yugi the Winged Kuriboh card, which he uses to defeat Dr. Crowler in the entrance exam. This stunt gains Jaden the immediate respect and admiration of his classmates, and he becomes one of the greatest duelists in the school (though occasionally underappreciated, due to his status in the "Slifer Red" dorm, the lowest dorm). Jaden's Joey-like enthusiasm for dueling makes him a valuable asset in the fight against the threats that he faces in Season 1, including the Shadow Riders and the Sacred Beasts.

SEASON 2
After passing all of his end of year exams, Jaden and friends return to Duel Academy for a second year. Jaden still has his enthusiastic personality, but regains much character development in Season 2, especially after meeting Aster Phoenix, a new first year who seems to match his calibre in dueling. Although, things quickly take a turn for the weird, and Jaden, after losing to Aster, becomes depressed and loses the abilty to see his cards. After returning from Neospace with new monsters, he manages to defeat Aster and rediscovers himself, continuing a fight against the evil and mysterious Society of Light.

SEASON 3
Although still a carefree duelist, Jaden appears to have more serious following the events of Season 2. After he and his friends are strangely transported to a different dimension, Jaden uses this newfound seriousness to keep his cool when his friends become duel zombies and his friend Jesse is sacrificed in the wake of a new (or perhaps old) threat. Blaming himself for this, Jaden begins to question himself as not just a duelist, but a human.

SEIYUU: Suzuki Masami
DEBUT: Episode 1 - The Next King of Games

Syrus is the weaker younger brother of Zane Truesdale, who is in the Obelisk Blue dormitory. He himself joined as a student in the Slifer Red dormitory along with Chumley Huffington and the main character, Jaden Yuki. He is a decent duelist, but has a great deal of self doubt, hindering his performance. He is later promoted to the Ra Yellow dorm after he defeats Ran, an Obelisk Blue student, in a duel. He was meant to spend his third year in Obelisk Blue after gaining a high score on his end of year exams the year before, but decided not to remain there.

Alexis is a strong female duelist from the Obelisk Blue dormitory at Duel Academia; Alexis, along with Zane Truesdale and Chazz Princeton, is in the best dormitory of the academy. She is regarded as the queen of Obelisk Blue, yet she does not follow the crowd nor does she regard herself as better than other people.

STATUS: Department chair of Techniques
DORM: Obelisk Blue

VOICE ACTOR: Sean Schemmel
SEIYUU: Sanae Kobayashi
DEBUT: Episode 1 - The Next King of Games

Think of Yu-gi-oh! GX as Harry Potter - You have Jaden (Harry), Syrus (Ron), Alexis (Hermione) and Chazz (Malfoy). Dr. Crowler? He's the Severus Snape of Yu-gi-oh! GX. The one teacher who picks his favorites among the students and picks on the others. He believes that only the extremely skilled duelists should be students, and he is always trying to find ways to get Jaden expelled. Oh and he has a PHD in dueling and hates Cats.

NAME: Chazz Princeton
JAPANESE NAME: Manjoumi Jun
AGE: 15 at debut, currently 17
STATUS: Third year student
DORM: Slifer Red, formerly Obelisk Blue (see below)
RELATIONS: Slade & Jagger Princeton (Brothers)
VOICE ACTOR: Sean Schemmel
SEIYUU: Sanae Kobayashi
DEBUT: Episode 1 - The Next King of Games

As I mentioned before, Chazz is the Draco Malfoy of Yu-gi-oh! GX. He is jealous of Jaden ever since he saw his performance in the entrance exam (clearly better than his performance) and will stop at nothing to prove he is capable of beating Jaden. Originally in Obelisk Blue, he temporarily transferred to North Academy for several episodes (and became Jaden Yuki's opponent in the annual "School Duel") but transferred back to Duel Academy following this. Under this technicality, he was forced into Slifer Red (as students joining mid-year cannot take an entrance exam and must "start from the bottom"), much to his dismay, and has remained there ever since.

NAME: Zane Truesdale
JAPANESE NAME: Marafuji "Kaiser" Ryo
AGE: 17 at debut, currently 19

Duel Academy has had hundreds of amazing duelists residing on its campus, but none as highly superior as Zane Truesdale. Zane was one of the most highly respected and top ranked duelists at Duel Academy. He is also the only person whom Jaden has been unable to defeat, although he came close in "Graduation Match", with the duel ending in a tie. After being beaten for the first time by Aster Phoenix, Zane lost all faith in his dueling skills and became the worst player in the league, before a brief but intense stint in the illegal "Underground duelist" leagues (a result of his desperation). Following this, he regained his old skills, but became a different Zane - a cold, heartless duelist who abandoned any respet he had for his cards. Then, he disappeared.

Bastian Misawa was the strongest duelist in Ra Yellow, and considers himself one of Jaden's closest friends. Although Jaden feels the same way, Jaden is sure that he is stronger than Bastian. In Season 2, Bastion became a follower of the light, but was freed after his love of science made him remember his old life and break the curse, in a similar way that Chazz was freed. After this, he ran off with his mentor and disappeared without a trace. In Season 3, after Jaden and the gang were transported to another dimension, it is revealed that Bastion was also trapped there after an experiment went wrong, and was able to use his intellect to assist the gang's return to the real world.

SEIYUU: Hiroshi Shimozaki

Tyranno Hassleberry was first depicted as a bully who picked on Jaden and his friends, despite being a year younger than them! He thought he was unbeatable, but when Jaden disproved that theory, he came to idolize Jaden, even taking to sleeping in the same room as him at the Slifer Red dorm, despite being in Ra. He is the son of a great army general, and therefore likes to pretend he is in the army, referring to his dorm as "The Yellow Barracks" and speaking with a sterotypical texan accent. He and Syrus often fight over who is a better friend of Jaden. He is a dinosaur duelist, and his favorite movie is Jurassic Park, as he can be seen wearing a Jurassic Park T-shirt in various flashbacks.

He is a good friend of Jaden when he comes to the school (at least it seems that way), but their views of duelling differ highly. Whilst Jaden believes that the thrill of duelling comes from the luck of the draw, and never knowing what's going to happen next, Aster believes that our future is set and that our destiny is written, hence the Destiny Heroes he uses. Although his story is resolved in Season 2, he becomes a recurring character and makes occasional appearances.

After the academy is sent to another dimension, Jesse is taken with them and assists Jaden and the gang in finding their way home. Although not clear at first, Jesse plays a large part in Jaden's character development; after he is sacrificed to Yubel so that the gang can return home, Jaden blames himself due to Yubel being his monster. This trauma plays a large part in Jaden's growing up.

He was originally the right hand man of Professor Thelonius Viper, but after Viper revealed his true intentions, he began assisting Jaden and the gang when they were trapped in the other dimension, as well as when they returned to find Jesse. Growing up, Axel trained with his mercenary father and now applies these techniques to dueling, claiming that the reason he duels so well is because he has trained his mind to duel as if his life depended on it. This mercenary background is reflected in his Volcanic Burn deck and unique Duel Disk (possibly of his own design) that takes on the appearance of a hand-held cannon when in standby.

He accompanies the gang to the alternate dimension, and is one of the few who do not become "Duel Ghouls", despite being seldom-seen throughout the ordeal. Of all the exchange students, he has been seen the least, but begins to play a vital role in the plot once the true nature of the situation reveals itself.

Until then, she begins as the mysterious voice that haunts Jaden in his sleep from below the academy. She then manages to posess Marcel, the french friend of Blair and uses this human appearance to fight on her own behalf. Using Marcel's body, she takes Duel Academy to the alternate dimension where enough energy is gathered by her in her duel with Jaden (especially due to the large energy generated by the Sacred Beasts, which she unearthed from their resting place) for him to discard Marcel's body and personify herself in a physical form, revealing her true identity to Jaden and continuing her rampage to the extreme.

Aki Izayoi is the female of the group, and possibly Yusei's love interest. What makes her so special is the "special power" she possesses, which seems to be a form of ESP.
