He is described as an energetic boy who comes to Duel Academy to learn to become the new King of Games. He enjoys seeking out new duel challenges and is known to be quite lucky when it comes to his draws. He is capable of communicating with Duel Spirits, most often conversing with Winged Kuriboh, a card he received from Yugi Mutou on the day of his entrance exam. He specializes in using Fusion Monsters, his main deck being the Elemental Heroes deck before later obtaining a set of Neo-Spacian monsters and his key card, Elemental Hero Neos. Following the third season, in which he entered an alternate dimension and confronted the duel spirit, Yubel, he has gained the powers of both The Supreme King, an evil alter-ego he temporarily took on, and Yubel, giving him powerful insight.

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

Syrus Truesdale, known as Sho Marufuji (丸藤翔 Marufuji Shō) in the Japanese version, is Jaden's roommate at Duel Academy. He often doubts himself, living in the shadow of his older brother Zane,^[2] but has shown himself to be a talented duelist, managing to rise in the ranks from Slifer Red to Ra Yellow to Obelisk Blue. He battles using a Vehicroid deck, which in season four becomes a Cyberoid deck that he creates by implementing Zane's Cyber Dark Dragon deck.

Chazz Princeton

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

Chazz Princeton, known as Jun Manjome (万丈目準 Manjōme Jun) in the Japanese version, is a freshman duelist who ranks in the Obelisk Blue. He is elitist, thinking that low-scoring duelists such as Jaden should be kicked out.^[3] He thus becomes one of Jaden's rivals throughout the series. It is revealed early in the first season of the series that his elitism stems from his older brothers who urge him to become a great duelist in order to have their family reign over the dueling world, as his brothers rule over the political and financial worlds. After becoming estranged with his brothers, Chazz decides to pursue a career in dueling, without their help. It is revealed that Chazz has a soft side in the second season. When Alexis's brother arrives to take his sister to make a band, they have a duel. During the duel, Chazz cheers on Alexis. He also has an awkward crush on her.

He initially uses a power based deck, focusing on powerful monsters such as the Armed Dragons. Later on, he becomes able to see duel spirits and starts using the Ojama Trio, a trio of brothers with zero attack points but several uses.

His self-imposed nickname in the English version is "The Chazz" while his Japanese nickname is "Manjoume Thunder," which is spawned from the phrase "It's Manjoume-san!" ("Manjōme-san da!"). In the manga, Chazz is a more serious character than his anime counterpart, and his main spirit card is Light and Darkness Dragon. Chazz's character design was overseen by Kenichi Hara.^[4] His usual outfit consists of a slightly tattered black jacket with gray trimmings and sharp edges flowing out the costume's lower back. Chazz originally wore the standard Obelisk Blue uniform, but switched to the black outfit after the leaving the school temporarily midway through the first season. He also wore a white version of his standard black outfit during his time in the Society of Light. His black hair is sectioned in two layers, his black eyes positioned directly beneath the bangs of the layer closest to his face. He carries an Academy-issued Duel Disk on his left hand.

Alexis Rhodes

Voiced by: Sanae Kobayashi (Japanese), Priscilla Everett^[5] (English)

Alexis Rhodes, known as Asuka Tenjouin (天上院明日香 Tenjōin Asuka) in the Japanese version, is a beautiful and talented duelist who is regarded as the queen of the Obelisk Blue. She is not elitist like many of the other Blue members, and quickly takes interest in Jaden.^[5] Later, it is also revealed that she loves Jaden. She duels using a Cyber Girl deck. Jaden accepted a duel with another player, and whomever won was to be engaged to Alexis, Jaden won but in the end had no idea what fiancee meant so Alexis responded " It means friends. At least for now, big guy." She also knows that Chazz has a crush on her.

In the timeline of the Yu-Gi-Oh! GX anime, Alexis, residing in the Obelisk Blue dormitory, along with Zane Truesdale and initially Chazz Princeton, is one of the top students at Duel Academy. She does not follow the crowd nor does she regard herself as better than other people like some students in the dormitory, but has a stern pride as an Obelisk Blue duelist.

Alexis mourns for her long-lost older brother,^[5] Atticus Rhodes. With the help of Zane, the top duelist at Duel Academia, she constantly searches for clues surrounding his disappearance, until it is revealed that he joined the Shadow Riders, under the control of Nightshroud.^[6] Defeated by Jaden Yuki in a Shadow Duel and relieved of this persona, the incident leaves Atticus amnesic, prompting his sister to engage in a duel with Titan to restore his memories.^[7]

Later in the series, Chazz comes out about his infatuation with Alexis after Jaden defeats the final Shadow Rider.^[8] Atticus helps Chazz with his crush and he steals all seven Spirit Keys needed to revive the Sacred Beasts in order to force Alexis to duel with him. Although Chazz plays suggestive cards such as Hidden Wish and Love Letter to show her how much he cares, Alexis wins in the end, stating that she cannot return his feelings, because she "loves dueling". Chazz's crush on Alexis continues throughout the series, although after having his free will sapped by Sartorius, his interests fade, until he is rescued by Jaden and returned to his former self.

At the start of the second year, Alexis moves into a spare room in the Slifer Red dormitory to escape Dr. Crowler, who was pestering her to begin a career with her brother as duelists that sings pop songs during duels.

Following Chazz's entrance into the Society of Light, Alexis duels with him to keep him from taking over Obelisk Blue completely. She fails, however, and meets the same fate as her fellow elites. Sartorius would subsequently strip Alexis of her mind completely, rendering her cold and heartless.^[9] Providing her with a new White Knight deck, he orders her to retrieve the key to the mind control satellite of Misgarth, which his good personality entrusted to Jaden, but was freed from his influence upon being defeated.

During the third year, when the Academy had been transported to another dimension, she protects the school with other students from monsters while Jaden and Jesse Anderson go to the Gecko submarine to get medicine for Blair. Later, she joins Jaden to search for Jesse in the second and third alternate universes, but she and several other of Jesse's friends are captured by Brron, the king of the alternate universe, and are all sacrificed and sent to the stars in an attempt to create the Super Polymerization Spell card, or so Jaden thinks, as they turn out to be alive, but trapped in another dimension.

During their graduation ceremony, Alexis and the others leave personal messages for Jaden in his bag, with Alexis's message asking Jaden if they can meet again somewhere.

His strength is in studying and preparing for different situations, relying on rational methods.^[10] He possesses six carefully calculated decks for each Monster attribute; he claims that a single carelessly added card can throw off their balance. At the end of season three, he stays behind in an alternate dimension to help out its inhabitants. In both the manga and anime, Bastion is shown to research those he seeks to duel to devise strategies to use against them; in both cases, he found a way to seal Fusion to keep Jaden from Fusion Summoning stronger Elemental Heroes. In the manga, Bastion is shown to use a Yokai deck (the cards were later made into real life ones, labeled as Zombie instead of Fiend).

However, all the underground duels, in which he battles using shock collars, causes his heart to become weak. He uses a Cyber Dragon deck which he later passes on to Syrus.

He is very strict, believing that weaker students who cannot keep up with his lessons should quit or be expelled. He especially dislikes Jaden, having been defeated by him during the latter's entrance exam. However, his attempts to show up or expel Jaden have only humiliated himself and his followers, while making Jaden look better and better. Crowler eventually appreciates his students and in turn is respected for his noble actions.

Crowler plays a deck called Ancient Gear, also known as Dark Medieval (暗黒の中世 Ankoku no Chyūsei) and (Antique Gear (古代の機械 (アンティーク・ギア) Anteīku Gia)) in the Japanese version cards. The majority of his monsters have the ability to prevent an opponent from activating Spell and Trap Cards until the end of the Damage Step. Crowler often employs various methods to speed up the summoning of his signature card, Antique Gear Golem, such as summoning (then subsequently sacrificing) the Troy Horse card, whose special ability allows it to be counted as a double sacrifice whenever Crowler summons a high-level Earth-attribute monster. His strongest monster is the Ultimate Antique Gear Golem which requires one Antique Gear Golem and two other Ancient Gear monsters, when its destroyed you can special summon one Antique Gear Golem from the graveyard.

When he is defeated by Jaden, his body dissolves into dust, but his spirit remains with Jaden, offering him advice whenever possible.

Antagonist groups

The Shadow Riders

The Shadow Riders known as the Seven Stars Assassins (セブンスターズ刺客, Sebunsutāzu Shikaku), in the Japanese version, are composed of seven duelists and their leader of varying origins and backgrounds who each have their own agendas. The Shadow Riders are intent on resurrecting the Three Sacred Beasts (Phantom Demons in the Japanese version).

Kagemaru (影丸): Voiced by: Nobutoshi Canna (younger), Mugihito (older) (Japanese), Marc Thompson (younger), David Wills (older) (English); Kagemaru is the leader of the Shadow Riders and the main antagonist of the series' first season as well as the former superintendent of Duel Academy. The "Kage" portion of his name is derived from the Japanese word "kage" (影), meaning "shadow."

In horrible health, Kagemaru hoped to attain eternal youth by sacrificing Duel Monster spirits to the Sacred Beasts. During his duel with Jaden, his youth was returned. After being defeated, however, he returned to his aged state. He then asked forgiveness and promised to renounce his former ways, carried off to the hospital by helicopter.

Kagemaru plays a Sacred Beast deck. He carries a basic Fiend deck to support Raviel, and plenty of Spell and Trap Cards to support Uria and Hamon.

Nightshroud / Darkness (ダークネス, Dākunesu): Voiced by: Hozumi Gōda, Kouji Yusa (Fubuki) (Japanese), Jason Griffith (Atticus) (English); Nightshroud is the first of the Shadow Riders . But in reality, Nightshroud is an entity of unknown origin tied to the darkness itself and the final antagonist in the series. He entered the body of Atticus Rhodes and took control. Darkness is voiced by Hozumi Gōda in the Japanese version. While possessing Atticus's body, Nightshroud is voiced by Kouji Yusa in the Japanese version and by Jason Griffith in the English version

Being the owner of the other half of the Shadow Charm pendant in Jaden's possession, Nightshroud sets a Shadow Game for both of them where the loser has his soul sealed in a card. When defeated, Nightshrouds' soul (represented by his mask) is sealed away, and Atticus is freed.

During the GX Tournament, Atticus uses Nightshrouds' deck in hopes of convincing his friend, Zane Truesdale, that the dark path taken by a duelist is a terrible course. As a result, Nightshrouds' influence (that lay dormant within his cards) is once again able to take control of Atticus, only to be banished following his defeat.

In the fourth season, Atticus again uses Nightshrouds' deck to duel Jaden, revealing he still has nightmares about his alter-ego. During the duel, Atticus remembers that one of the missing students at the academy, Yusuke Fujiwara, was the original host of Nightshroud and before he vanished, he made Atticus into a temporary host for Nightshroud to inhabit. But Nightshroud eventually returns in the body of Fujiwara, and though he loses to Atticus in a one-on-one duel, he cheats reversing time and preventing Atticus from activating Inferno Fire Blast. But, after losing to Jaden when he and Jesse double teamed Yusuke, Nightshroud left his vessel and duels Jaden in a match with the world at stake. Jaden reverses all of Nightshrouds' evil doings and finally destroys him. Though beaten, Nightshroud boasts that as long as there is darkness in humans, he would return, but Jaden counters by claiming that as long as there are bonds between humans, Nightshroud has been sealed. In his final duel, Nightshroud is portrayed as a megalomaniac or simply insane, once he claims he is God and the Savior.

Nightshroud, while possessing Atticus, plays a Red-Eyes Darkness Dragon deck, which focuses on quickly summoning the eponymous card and strengthening it by placing a large number of Dragon-type monsters in his Graveyard. Once within the body of Yusuke, Nightshroud uses a Clear deck which shuts down the opponent's strategies based on the attributes of the monsters they summon. Once without a host, Nightshroud uses his personal Darkness deck, which controls the field through its "Darkness" Field Spell card.

Camula (カミューラ, Kamyūra): Voiced by: Kanako Irie (Japanese), Bella Hudson (English); Camula is the second of the Shadow Riders. Her name is derived from the title of Joseph Sheridan le Fanu's novel, Carmilla.

A vampire, Camula is very serious when it comes to dueling, as she hopes to revive her race from its destruction by the people of Medieval Times. She had been asleep within her coffin until Kagemaru uncovered it and invited her to join the Shadow Riders. She captures the souls of her opponents following their losses within dolls to fuel her cause, and uses the Shadow Charm strangler around her neck to bet the souls of others in conjunction with the Shadow Game-exclusive Illusion Gate to ensure victory. She manages to obtain the keys of Dr. Crowler and Zane, but during her duel with Jaden, her Shadow Charm's power is negated by the completed item that Jaden possesses. Out of self-confidence, Camula places her own soul on the line, and it is dragged into the gate after she loses, leaving her body empty and turning it to dust.

Camula plays a Vampire deck. Several of her monsters (such as Immortal Werewolf and Vampire Bats) can feint revival by either summoning or discarding additional copies of themselves when destroyed through battle. Camula is also able to combine the recursion ability of Vampire Genesis with Genesis Crisis to repetitively raise her undead army from the grave.

Tania / Tanija Amazoness (アマゾネス・タニヤ, Amazonesu Taniya): Voiced by: Kazue Komiya (Japanese), Alyson Johnson (English); Amazoness Tania is the third of the Shadow Riders.

A white tiger that assumes human form with her Shadow Charm gauntlet to find a worthy duelist to be her husband, Tania travels with another tiger named Bass, who resembles the Amazoness Tiger. She falls in love with Bastion Misawa, and after some sweet talking and showing off her amazing dueling skills, defeats him and makes him her bridegroom for a short time until she grows tired of him. Tania then fights Jaden in a soul match with the effect of Amazoness Arena, and eventually resumes her true form and runs off. She appears before Jaden and his group during the third year as her human self, having been sucked into the second alternate dimension they visit since their last meeting. She serves as their guide through the first town they encounter, and stays behind with Bastion after Jaden liberates it.

Tania's Amazoness cards, based on the Amazons of Greek mythology, are divided into two decks: Courage and Knowledge (the former focusing on offense with more damage inflicted via Amazoness Arena, while the latter is more based on turning the opponent's battle strategies against them). She uses the Knowledge deck against Bastion, and the Courage deck against Jaden.

Don Zaloog / Chief Zaloog (首領－ザルーグ, Shuryō Zarūgu): Voiced by: Taiten Kusunoki (Japanese), Darren Dunstan (English); Don Zaloog is the fourth of the Shadow Riders.

Zaloog is actually a Duel Monster spirit brought to life by the power of the Shadow Charm eyepatch he wears. He is also the leader of the band of thieves known as the Dark Scorpion Gang, (Black Scorpion Graverobber Gang (黒サソリ盗掘団 Kurosasori Tōkutsu-dan) in the Japanese version), who were also brought to life by the Charm. He masquerades as a detective named Detective Zaloog (Police Inspector Manguer in the Japanese version), sent to assist the students in hiding the remaining Spirit Keys, while his posse work on taking the keys incognito. However, since they fail to obtain the keys in a duel, they are unable to unlock the Spirit Gate of the Three Sacred Beasts. When Zaloog and his gang are discovered, he and Chazz Princeton duel with all the remaining keys on the line. In the end, he and his cohorts are defeated, and the power of his Shadow Charm is nullified. After reverting to their spirit forms, the Dark Scorpions join the many weak monsters in Chazz's care, to the young duelist's annoyance.

Zaloog plays a Dark Scorpion deck, themed on bringing together the members of the Dark Scorpion Gang and triggering their five effects in unison, with support from cards such as Mustering Of The Dark Scorpions" and Dark Scorpion Combination. Unlike his English print card, however, he wields guns.

Abidos III (アビドス3世, Abidosu San-sei): Voiced by: Mamoru Miyano (Japanese), Darren Dunstan (English); Abidos the Third is the fifth of the Shadow Riders. His name is derived from the name of the ancient Egyptian city, Abydos.

An ancient pharaoh who never lost a single duel, Abidos regained physical form through the powers of the Shadow Charm headband he wears. With an army of mummies, Abidos gathers Jaden and company on his celestial yacht for a duel. During the duel with Jaden, Abidos realizes that the only reason he kept winning was because his opponents always lost on purpose, simply because he was pharaoh. Jaden, however, manages to give Abidos a real duel in which the opponent actually tries to win. Satisfied with his defeat, Abidos departs for the afterlife, giving Jaden his Shadow Charm, the latter making a promise to meet him again in one-hundred years time, presuming that Jaden will be dead within that time.

Abidos plays a Servants of the Pharaoh deck, themed on gathering three Sarcophagus cards to summon Spirit of the Pharaoh.

Titan (タイタン, Taitan): Voiced by: Norio Wakamoto (Japanese), Eric Stuart (English); Titan is the sixth of the Shadow Riders.

A hitman originally hired by Crowler to deal with Jaden, Titan captured Alexis Rhodes to force Jaden into a duel for her life. Despite his reputation of possessing the power of a Millennium Item, the "Millennium Item" turned out to be a fake Millennium Puzzle, and Titan used various tricks to mimic a Shadow Game. He became the victim of a real Shadow Game, however, but was saved by Kagemaru, wearing a Shadow Charm mask to bind him to the real world. Taking advantage of Alexis's desire to restore her brother's memories, Titan challenges her in the abandoned dorm where they first met. He is ultimately pulled back into the pits of darkness when he is defeated.

Titan plays an Demon (Archfiend in the English version) deck, composed largely of monsters based on chess pieces, in his first encounter with Jaden, which is later supported by Demon's Matador (Fiend Bullfighter) cards in his duel with Alexis; this last deck is inspired by Spanish traditions with names related to bullfighting, such as "Picador," "Matador," and "Banderillero."

Amnael (アムナエル, Amunaeru): Voiced by: Kappei Yamaguchi (Japanese), Wayne Grayson (English); Amnael is the seventh and final member of the Shadow Riders.

A homunculus inhabited by Banner's soul. Unable to find Banner's cat Pharaoh, Alexis Rhodes, Chazz Princeton, Jaden Yuki and the others start looking for him. While looking, Amnael challenges and defeats both Chazz and Alexis in a duel, who then get sucked into Amnael's book as a result. Jaden gets lead to the abandoned dorm where he defeated Titan. There he finds a mummified body that resembles Banner, and Amnael who later reveals himself to be the spirit of Banner. Amnael and Jaden duel, which results in Jaden's victory. After giving Jaden his Emerald Tablet which previously held his Shadow Charm, Banner is reduced to dust along with his original mummified body. His spirit, however, lives on in the stomach of Pharaoh. His appearance is seen when the cat is clueless causing its body to retrieve Banner's spirit for a short amount of time.

Society of Light

The Society of Light (光の結社, Hikari no Kessha) is a cult led by the alien-influenced Sartorius, the Society of Light's legion of followers dedicate themselves to worshipping the Light of Destruction, and are intent on cleansing the Earth of its deficiencies.

Sartorius Saiou / Takuma Saiou (斎王琢磨 Saiō Takuma)

Voiced by: Takehito Koyasu (Japanese), Maddie Blaustein (English)

Sartorius is a fortune-teller with dual personalities under the influence of The Light Of Destruction. Sartorius serves as the main antagonist of the series' second season, poised to remake the world in the image most befitting the extraterrestrial radiance within him.

Lorenzo Plata / Ryusei Gin (銀流星, Gin Ryūsei): Voiced by: Kazuhiro Shindou (Japanese), Anthony Salerno (English); Lorenzo is the champion of the "Shooting Game" arcade game. His name means "silver meteor" when translated in Japanese order.

Lorenzo is employed by Alexis and Chazz to duel Jaden. Although he is defeated, he comes to understand his opponent's definition of a fun duel, but is punished by Sartorius for his failure. Leaving his hair stark white, Sartorius takes complete control of him and his future.

Lorenzo plays a Giant Battleship (巨大戦艦 Kyodaisenkan) (known as B. E. S. in the English version) deck. With the effect of Boss Rush, Lorenzo is able to continuously summon Giant Battleship monsters as they are destroyed, causing extra damage with Cyber Summon Blaster. The flaw of this strategy, however, is that he is no longer able to summon in any other manner as long as Boss Rush remains in play.

The concept of Lorenzo's cards is derived from the Konami video game series, Gradius. The "Core" monsters are all based on signature Bosses from the games, and the term Boss rush is derived from a gameplay mode commonly found in the series.

In the English dub, he speaks in a Italian accent.

Princess Rose (プリンセス・ローズ, Purinsesu Rōzu): Voiced by: Hiroko Kasahara (Japanese), Veronica Taylor (English); Princess Rose is a representative selected by Sartorius to duel Jaden in his place.

Rose claims to have the ability to see Duel Monster spirits (manifested as three "princes" named Jeffrey, Roosevelt and Percival in the English version), but others do not believe her. Jaden, however, notices the spirit of a frog prince watching over her following their duel.

Rose plays a Frog deck. Through the effects of her trump card Des Frog, as well as Tadpole, Rose is able to summon three copies of the former relatively quickly. With her assault team in play, she is able to neutralize all threats and constantly strengthen her monsters with various other cards.

In the English dub, she speaks with a Valley girl accent.

Tsugio Kanda / Bob "Game Show" Banter (神田次男, Kanda Tsugio): Voiced by: Ryo Kubota (Japanese), Matthew Charles (English); Bob Banter is the Game Show King who has feelings for Alexis. His name in the English version is a pun on the name of Bob Barker.

Saddened by the fact that Alexis never remembers his name (in the English version, she instead considers him uninteresting), Bob duels Jaden in hopes of impressing her.

Bob plays a Quiz (Game Show) deck, which sets up the duel as a game show, with Bob as the host. The majority of his monsters possess abilities that activate when they are flipped face-up, causing damage to opponent if he is unable to answer a posed question correctly, or inflicting damage to himself if he does answer correctly. Once his Quiz Panels are depleted, the summoning of Nazora Panel 9 allows Bob to return all of them to his deck for another round.

In the English version, he makes references to numerous existing game shows including The Price Is Right, Whammy!, and Who Wants to Be a Millionaire?.

Howard X. Miller / Echs (エックス, Ekkusu): Voiced by: Yoshitada Otsuka (Japanese), Ted Lewis (English); X is a Pro League duelist for the Society of Light. His name is meant to be a pun in English, as "mill" (a term borrowed from Magic: The Gathering) denotes a direct disruption of a player's deck.

X is a Pro League duelist associated with the Society of Light whose ranking is greater than Aster's. In the English version, X of dreamt becoming a pastry chef as a child, but instead grew up to become an attorney. He successfully reduced the cards in Jaden's deck to zero, but lost when Jaden was unable to draw, due to the effect of the Neo-Spacian Glow Moss he had summoned on X's field, causing him to discard his deck.

X plays a Deck Destruction deck. His strategy relies primarily on Monster Register, a card that, under normal circumstances would effectively demolish the decks of both players. X, however, cleverly protects himself with the ability of Trap Sloozer, while rendering himself almost untouchable with a wide array of Spells and Traps.

Prince Ojin / Prince Odin (オージーン王子, Ōjīn Ōji): Voiced by: Hisayoshi Suganuma (Japanese), Darren Dunstan (English); Prince Ojin is a professional duelist and celebrity from Misgarth. His name is meant to be a pun, as "ōjin" is the Japanese word for "royal person".

Ojin dueled against Sartorius in the GX tournament. He gloated that he would defeat Sartorius with one attack, but was himself defeated before Sartorius's first turn even came. Upon his defeat, he fell under Sartorius's influence and provided him with the control switch to his mind control satellite. He returns later in the tournament to retrieve one of the switch's keys given to Jaden by Sartorius's good personality, but fails despite aid from the Dark Light. While Jaden and Sartorius face one another in their final duel, Ojin falls under Sartorius's control once again, and is successful in arming the satellite.

Ojin plays a Satellite deck. His strategic preference involves devoting all his resources to performing a "One Turn Kill" with Satellite Cannon. In the case that this maneuver fails, he is also able to fuse three copies of the said monster together to summon Satellite Laser X-06S Balsam by activating Debris Station for a final wave of destruction.

Dr. Einstein / Dr. Albert Zweinstein (アルバート・ツバインスタイン博士, Arubāto Tsubainshutain Hakase): Voiced by: Takeshi Aono (Japanese), Sean Schemmel (English); Dr. Eisenstein is a nine-time Nobel Award-winning German physicist, with an IQ of 173, specialized in duel physics. His name is a pun on the name of Albert Einstein. Eisenstein arrives at Duel Academy under Prince Ojin's request, and is sent by Sartorius to eliminate Jaden and retrieve his key to the mind control satellite, though his underestimation of the young duelist's tactics results in his failure. Bastion idolizes him for his unified theory of the world.

Sarina Saiou / Mizuchi Saiou (斎王美寿知, Saiō Mizuchi): Voiced by: Tomo Sakurai (Japanese), Bella Hudson (English); Sarina is Sartorius's younger sister.

A Priestess, Sarina granted her assassins special abilities with her own powers, and erected a barrier around Domino City that prevented Duel Monster spirits from leaving the boundary while Frost and Thunder dueled Hassleberry and Syrus. After disposing of her subordinates, she challenged Aster and Jaden to a Tag Duel in KaibaLand's virtual system, but was ultimately defeated. Sarina then revealed that she wished to save her brother from the influence of an evil aura housed in a Hero card that was shown to him when they were younger. In a final act of gratitude, she helped those trapped within the virtual world to escape, but was left behind in the collapsing program, digitizing herself to act as her brother's "guardian." While no mention of it is made in the English adaptation, the Japanese version further includes a promise by Solomon Moto to speak with Seto Kaiba in hopes of restoring her consciousness. Sarina returns near the end of the second year, contributing to the mind control satellite's end. She is flown in to Duel Academy via helicopter by Kaiba's associates, and reunited with her brother.

Sarina plays a Mirror deck. Each of her Shikigami (式神) (Silver Spirit in the English version) monsters, is either sent to the Graveyard to activate Mirror Bind, or to use as fodder for Full Moon Mirror. Once a collection of ten counters has collected on the latter, she is able to play Infinite Fiend Mirror to summon nine copies of her powerful The Dark Creator (based on an illustration by Toshiki Nakayama (中山俊希 Nakayama Toshiki) submitted for a card illustration contest held earlier during the series) to the field. The concept of Sarina's cards is derived from onmyōdō, and she herself takes on the role of an onmyōji during episodes in which she makes appearances.

In Italian version she's called Sabrina.

The Four Monarchs (四帝, Yon Tei), known as the Light Brigade, in the English version, is a group of assassins in Sarina's service.

Ikazuchimaru (雷丸), known as Thunder in the English version (voiced by Jamie McGonnigal / Takanori Oyama): The "Ikazuchi" portion of the his name in the Japanese version is derived from the word "ikazuchi" (雷), meaning "lightning."
Kourimaru (氷丸, Kōrimaru), known as Frost, in the English version (voiced by Marc Thompson / Hidenobu Kiuchi): The "Kouri" portion of his name in the Japanese version is derived from the word "kōri" (氷), meaning "ice," and he sports a Hispanic accent in the English version.
Honoumaru (火丸, Honōmaru), known as Blaze, in the English version (voiced by Sam Riegal / Masaki Ishikawa): The "Honou" portion of his name in the Japanese version is derived from the word "honō" (火), meaning "fire."
Iwamaru (岩丸), known as T-Bone in the English version (voiced by Sean Schemmel / Toshiharu Sakurai): The "Iwa" portion of his name in the Japanese version is derived from the word "iwa" (岩), meaning "rock," and he speaks like a rapper in the English version.

Martin Empire

Yubel (ユベル, Yuberu): Voiced by: Hiromi Tsuru (Japanese), Cassandra Lee Morris (English); Yubel is a duel spirit that is owned by Jaden and the true antagonist of season 3. He is bae. When Jaden was a child, Yubel was protective of him and caused anyone to come near him to fall into a coma. Jaden had sent Yubel into a capsule which was fired into space in hopes of her coming in contact with the Darkness of Justice in order to cure her of her protectiveness. However, the capsule that Yubel was in became affected by the Light of Destruction, driving her insane and causing her to begin to believe that love and suffering are the same thing. When she returned 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 body she would bring his dead son back to life. However, Yubel used Viper to her own ends and, after getting what she wanted, killed Viper. Yubel would possess Marcel's body and afterwards Jesse Anderson's body all to show Jaden how much she loves him through the pain her actions bring to him. She carries a pathological hatred for Jaden's friends and loved ones, out of the belief that they stole him from her. In the end, during the duel with Jaden, he would merge his soul with Yubel's, bringing her peace. Yubel plays a fiend/plant deck that featured her own card.

Marcel Bonaparte / Maltin Kano (加納マルタン, Kanō Marutan): Voiced by: Asako Yoshida (Japanese), Sebastian Arcelus (English); Marcel Bonaparte is a Ra-Yellow student and the son of Vice Chancellor Bonaparte. Marcel was always depressed at the sight of his parents fighting all the time and he became even more depressed when his father left home, leaving him with his mother. Marcel was possessed by Yubel after she sensed how he suffered. However, he would be freed from her control after Yubel gained enough energy to sustain her body and did not need him anymore. 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 / Professor Cobra (プロフェッサー・コブラ, Purofessā Kobura): Voiced by: Masaya Takatsuka (Japanese), Sean Schemmel (English); Professor Thelonious Viper was a major antagonist. During a mission with his comrades, he found a baby boy all by its lonesome. When Viper went after the baby his comrades went in another direction and got blown up by a bomb (captured in the English version). Believing the baby saved his life, Vipr vowed to raise him as if he were his own. Naming the boy Rick (called Pierce in the English version), Viper adopted and raised him. One day, Viper gave Pierce a deck of Duel Monster cards as a present but they were blown away by the wind. When Pierce went after them, he was hit by an on-coming truck and was killed (in the English version, Pierce was said to have died of a disease). In another mission, Viper encountered Yubel, who sensed the darkness in his heart and offered to resurrect Pierce if Viper were to gather enough energy to revive it, to which Viper agreed to do. Viper entered Duel Academy a couple of years later and gave Death-Belts (Bio-Bands in the English version) to the students of the academy in hopes 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 that duel did revive Yubel. However, Yubel double crossed Viper and, instead of bringing Pierce back to life, it cast Viper in a 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. Professor Viper played a snake-themed deck.

Alien of Light (光の宇宙人, Hikari no Uchiujin) (voiced by Wayne Grayson / Takahiro Hirano): The Alien of Light's duel with Jaden, which was arranged by Neo-Spacian Aqua Dolphin, serves as a test of the boy's abilities to wield the powers of darkness. It plays a Different Dimension deck, primarily centered on Candelato, the Beast Of Light. Although the card prevents its controller from drawing any additional cards during the Draw Phase, the Alien of Light takes advantage of its simple summoning conditions as a means of brute force.
(Black Magician Girl (ブラマジガール, Buramajigāru), known as Dark Magician Girl in the English version) (voiced by Bella Hudson / Yuki Nakao): A Duel Spirit towards whom Syrus Truesdale harbors feelings for, Dark Magician Girl surfaces during a school-wide festival to duel with Jaden.

While searching for his friends in another world, Jaden meets a Gravekeeper's Assailant named (Sara (サラ), Yasmin in the English version) (voiced by Lisa Ortiz / Yūko Mizutani), who rescues him from harm, and Jaden develops a little crush on her, though he is ultimately captured and forced to duel the Chief in a Shadow Game. He plays a Gravekeeper deck, which focuses on the wide range of abilities available with his "Gravekeeper's" cards, as well as preventing both players from activating cards that interact with the Graveyard.
Supreme King advisors: consisting of Skilled White Magician, Skilled Dark Magician, Skull Knight, Chaos Sorcerer, and Guardian Baou, they serve as henchmen to Jaden while under the guise of the Supreme King. All but Baou are destroyed, prior to Jaden's defeat, and Baou is dispatched by Jaden himself afterwards.
Birdman (バードマン, Bādoman, Harpie's Brother in the English version) (voiced by Sean Schemmel / Akio Suyama): A winged warrior who guards the power generator in the second alternate dimension that Jaden and his companions visit.

(Android - Psycho Shocker (人造人間サイコショッカー, Jinzo Ningen Saiko Shōkā), Jinzo in the English version) (voiced by Sean Schemmel / Satoshi Tsuruoka): An evil Duel Spirit who seeks to become a real person, Jinzo takes the souls of those who summon him. This may be the case because Jinzo is a Dark-attribute monster. A group of three students including Takadera (高寺) (Torrey in the English version) unwittingly call him forth, but was defeated by Jaden in a Shadow Game and forced to give up his ambition. He plays a Psycho deck, which includes spirit-related cards in addition to himself as a trump card.

He intended to quell Jaden's worries regarding Shadow Games, and thus sarcastically threw around the possibility that he himself may have been initiating such a battle with Jaden. He plays Seto Kaiba's deck, complete with his three legendary Blue-Eyes White Dragon cards. The card that represents himself can be sacrificed to Special Summon a Blue-Eyes from his hand.
Honest - An angel who belongs to Yusuke Fujiwara, before being put away in a box when Yusuke goes to the darkness. At the beginning of Season 4, he disguises himself as Yusuke and uses his powers to manipulate the memories of the others into thinking he's been there all along.

Following Duel Academy's arrival in an alternate dimension, he encourages the students to save his son Marcel from the Duel Spirit Yubel.; Previously married, Bonaparte's son is in the custody of his ex-wife. After Marcel is rescued, Bonaparte apologizes for neglecting him and leaving his wife for his career, and the two return to France at the end of the season.

In both the English and Japanese versions, Bonaparte speaks French on occasion. In the latter, he also refers to himself with the archaic "wagahai," and ends the majority of his sentences with "de aru." In the English anime, he frequently uses the French terms "faux pas" and "au revoir."

The other characters do not recognize him immediately, and he is lonely due to most of his students either being promoted to Obelisk Blue or staying with Jaden at Slifer Red. Although the characters do not recognize him, Sartyr points out through a series of flashbacks that he had been a background character in several episodes in the first season as an in-joke about his character not being noticed.

Sartyr plays a Spice deck. By removing his own cards from the game with Curry Pot, he is able to summon Curry Fiend Roux and increase its strength with cards such as Red Pepper Spice and Spell Spice Caraway.

Belowski plays a Mokey Mokey deck. With the Spell Card Mokey Mokey Smackdown in play, Belowski's naturally weak Mokey Mokey monsters are able to pose a formidable threat to his opponents. By combining this with Human-Wave Tactics, Belowski is able to keep up a supply of monsters as fodder to trigger Smackdown's effect, albeit at the cost of his own Life Points.

Despite its possession, Dimitri is defeated by Jaden as he lacked the same heart that Yugi put into creating his deck.

In the English version, Dimitri refers to his Spell Cards as "Magic Cards," as this was the term used in the original Yu-Gi-Oh! series before the revised printing format of the TCG took effect.

While the whereabouts of his physical body after the Duel is explained as being absorbed by Plasma (showing Doctor Collector's face on the left wing of Plasma during the confrontation between The D and Aster Phoenix) in the English version, the fire caused by the Ultimate Destiny Card in the Pro League stadium is linked to his death in the Japanese version, though DD believes it was in fact the shock of being defeated that proved fatal.

Doctor Collector plays a Spellcaster Lock deck.

Honest is later destroyed by Trueman when he sacrifices himself to help Jaden, but Jaden adds him to his deck and uses him in his third rematch against Trueman.

It is unknown if this is his real deck, or only his deck while possessed. However, it seems that deck itself is a reflection of either of Yusuke's (Nightshroud's) beliefs - individuality brings suffering while nullification relieves it. Only two of the cards in his deck are available in the US the first being "Clear Vice Dragon" his trump monster and "Clear World" his most used card.

After the army of Truemen defeat all but Atticus Rhodes, Atticus uses the power of Nightshroud to undo the amnesia Trueman has inflicted upon him and challenges their leader, Yusuke Fujiwara.
