All seasons

Duel Monsters

Several Duel Monster spirits not directly linked to the main cast appear throughout the series.

  1. Alien of Light (光の宇宙人 Hikari no Uchiujin?) (voiced by Wayne Grayson / Takahiro Hirano): Alien of Light's Duel with Jaden, 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 around 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.
  2. Dark Magician Girl (Blamagigirl (ブラマジガール Buramajigāru?) in the original Japanese language 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. She plays Spellcaster deck, which centers around her own card (much like Yubel) and its related support.
  3. Dark World (暗黒界 Ankokukai?): A dictatorship of legendary monsters hailing from the world of the humans trapped in the third alternate dimension that Jaden and his companions visit. Its army is composed of numerous advisors and foot soldiers, and is headed by Dark World's king, Brron. None prevailed against Jaden.
  4. Freed (フリード Furīdo?) (voiced by Yūji Kishi): The captain of the Steel Knight army which protects the humans trapped in the third alternate dimension that Jaden and his companions visit, including the daughter and son of one of his battalion, Lars. He leads the fight against the Dark World monsters, and sacrifices himself to give Jaden a fighting chance against its knight, Zure.
  5. Gravekeeper's Chief (墓守の長 Hakamori no Chō?) (voiced by Tom Souhrada / Bin Shimada): The leader of the Gravekeeper's who demands that all intruders seen as tomb robbers be buried alive. While searching for his friends in another world, Jaden meets a Gravekeeper's Assailant named Yasmin (Sara (サラ?) in the original Japanese language 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 Duel. 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.
  6. Supreme King advisors: consisting of Skilled White Magician, Skilled Dark Magician, Skull Knight, Chaos Sorcerer, and Guardian Baou, they serve as henchman to Jaden while under the guise of Supreme King. All but Baou are destroyed prior to Jaden's defeat, and Baou is dispatched by Jaden himself afterwards.
  7. Harpie's Brother (バードマン Bādoman?, Birdman in the original Japanese language version) (voiced by Akio Suyama): A winged warrior who guards the power generator in the second alternate dimension that Jaden and his companions visit. He plays a Winged-Beast deck, which concentrates on the Direct Damage capabilities of Simorgh, Bird of Divinity and reflects his world's view that lower-level monsters are inferior to those of greater rank.
  8. Jinzo (Android -Psycho Shocker- (人造人間 サイコショッカー Jinzo Ningen Saiko Shōkā?) in the original Japanese language 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 Torrey (Takadera (高寺?) in the original Japanese language version) unwittingly call him forth, but was defeated by Jaden in a Shadow Duel 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.
  9. Kaibaman (Friend of Justice - Kaibaman (正義の味方 カイバーマン Seigi no Mikata Kaibāman?) in the original Japanese language version) (voiced by Eric Stuart / Kenijirou Tsuda): A monster modeled after Seto Kaiba, Kaibaman duels and defeats Jaden after he and his friends happen upon the Duel Monsters world. He intended to quell Jaden's worries regarding Shadow Duels, 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 summon a Blue Eyes from his hand.
  10. Honest - An angel who belongs to Fujiwara Yusuke, before being put away in a box when Fujiwara goes to the darkness. At the beginning of Season 4, he disguises himself as Fujiwara and uses his powers to manipulate the memories of the others into thinking he's been there all along. However, Jaden's powers show his true form, and Honest later resides inside Jaden's body until he and Jesse face Fujiwara, in which Honest returns to Fujiwara's side following his defeat.

Although the characters do not recognize him, Satyr 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.

Belowski returns during the second year as one of the few Obelisk Blue students left untouched by the Society of Light, and participates in one Duel of the GX tournament against Elroy Prescott, who becomes so tired from the boy's special ability that he forfeits the match.

Belowski plays a Mokey Mokey (Moke Moke) deck. With the Spell Card Mokey Mokey Smackdown in play, Belowski's naturally weak Mokey Mokey monsters are able to pose a formidable threat for his opponents.

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.

By using the field spell Clear World, Yusuke is able to activate a variety of debilitating effects depending on what attribute his opponent's monsters are, and avoid having to suffer such effects himself through the effect of Clear monsters that are not treated as having an attribute. 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.

He sports a standard season 1-3 duel disk and he is first shown whearing a obelisk blue uniform with a single large triangle coat tail and large shoulders on the uniform. He is later shown whearing a costume similar to his old friend Fubuki's Darkness clothing but with a blue rib cage like patern on the under shirt. He also uses a mask similar to Fubuki's but Fujiwar's covers the entire face and enficises the points more than Fubuki's. A piece of his mask breaks off during his duel with Fubuki and he removes the uper part of his mask leaving only the jaw line of his mask on his face for the rest of the time he is the avatar of Darkness.


Trueman (トゥルーマン Turūman?), also called Mr. T (ミスターT Misutā T?), is a mysterious being made up of dark energy that appears at Duel Academy to duel Jaden several times. There are more than one of him, however, so if the Trueman Jaden duels is the same one each time or not is uncertain. Trueman claims he is named as such because he speaks only the truth. Trueman eventually assaults the city of Domino and possesses or kidnaps most of its citizens as a ploy to lure Jaden Yuki away from Duel Academy, allowing him to assault the school by possessing the student Taigo Sorano. 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. During Jaden's duel with Yusuke, all the Trueman clones are killed by Rainbow Neos.

Trueman plays a Dark deck, focusing on powerful Dragon and Fiend-type monsters and summoning them quickly at the cost of his own Life Points through the effect of Dark Archetype. He can also mimic the decks of others by consuming the darkness in their heart, like Axel Brody's dad's Volcanic deck and Sorano's Horus deck.

Trueman is similar to Agent Smith an antagonist from The Matrix films.

However, when Zane's health fails, Syrus Truesdale duels Makoto in Zane's stead and defeats him.

Makoto plays a Psycho deck, centering on Jinzo (also called Android - Psycho Shocker) and its evolved form Jinzo Lord. As opposed to the direct and aggressive style of Zane's Cyber-Style deck, Makoto's Psycho-Style deck is subtler in its tactics, relying on disabling his opponent's ability to play certain cards and inflicting Direct Damage.

Tsutomu (ツトム?) is a young boy residing in Domino City. He is frustrated that he is "not strong enough" at dueling, and is consoled by Trueman, who appears due to "the darkness in (Tsutomu)'s heart". He joins Trueman by his own accord in order to "become stronger", but later appears to be possessed by Trueman. He is used by Trueman to gain control over the rest of the residents of Domino City. It is also Trueman in disguise as him who corners Axel Brodie while the latter was investigating the city.

Taigo Sorano

Taigo Sorano (空野 大悟 Sorano Taigo?) is a top-ranked Obelisk Blue student in his second year who duels Jaden in the graduation tournament. After losing, Sorano is possessed by Trueman and used to duel the rest of the Academy.

Sorano plays a Horus deck, relying on Horus the Black Flame Dragon. By combining the ability of Horus's Level 8 form with Royal Decree, Sorano is able to negate the opponent's ability to play spell and trap cards and then overwhelm them with Horus' high attack strength.


Koyo and Midori Hibiki

Koyo (響 紅葉 Hibiki Kōyō?) and Midori Hibiki (響 みどり / 響先生 Hibiki Midori / Hibiki-sensei?) are recurring characters. Koyo's full name means "autumn colors".

Koyo decided to duel a young Jaden while in a Tokyo hospital despite his failing health. During the duel, Koyo barely manages to finish, and later falls into a coma. In a flashback it is revealed that Chazz received an autograph from him, and in the process, Koyo's Winged Kuriboh altered Chazz's Light and Darkness Dragon card.
