The Admiral, known in Japan as Anacis 「アナシス, Anashisu」 is a man who travels the sea in a submarine and docks at Duel Academy. Arrogant and ambitious, he believes that everything (and everyone) in the world can be bought with money. Admiral challenges Jaden to a duel, who at first thought he was one of the Shadow Riders due to his interest in the Sacred Beasts. Halfway through the duel, the Admiral offers Jaden a position in the new Duel Academy he was building under the sea, even going so far as to buying Jaden. When Jaden rejects the offer, he places a bet on the outcome of the duel. Even though he ultimately loses the duel, the Admiral kidnaps Jaden, who isn't seen until a week later, riding on a motorboat and claiming to have escaped when the Admiral wasn't looking.

In the English dub, the Admiral is voiced by Ted Lewis, while Kazuhiko Nishimatsu takes the role in the Japanese version. In the English dub, the Admiral has a stereotypical pirate accent, and uses phrases such as “Shiver me timbers!”, in addition to making references to “doubloons” and “booty”.

The Admiral uses a Deepsea Deck based around the Field Spell Card "A Legendary Ocean" and focuses on summoning powerful monsters such as "Levia-Dragon - Daedalus".

Belowski, known in Japan as Mokeo Motegi (茂木もけ夫, Motegi Mokeo), is an Obelisk Blue pupil and the former top student of Duel Academy who has the power to communicate with Duel Monsters. Belowski is a laidback, carefree, peace-loving boy who isn't afraid to take a nap at the most precarious of times. Those in his presence gradually fall asleep without proper precautions, and therefore he is confined to his own personal dorm, "a secluded paradise within the depths of the school" as Dr. Crowler calls it. Because of his unusual talent in making those around him woozy, Crowler sets up a duel between Belowski and Jaden in hopes that Belowski's power might affect Jaden long enough for him to lose the duel, thus expelling him from the academy. However, Jaden's excitement and passion for dueling overwhelms Belowski's power and he ends up winning anyway, in which Belowski promptly dozes off after their duel.

Belowski returns during the second year as one of the few Obelisk Blue students left untouched by the Society of Light, and participates in a duel of the Genex tournament with Elroy Prescott, who becomes so tired from the boy's special ability that he forfeits the match. He is last seen rejecting Crowler and Bonaparte's offer to become a representative of the school, and choosing to take a nap under the shady trees instead. He made a cameo in Episode 179 watching Jaden's Graduation ceremony.

In the English dub, Belowski is voiced by Darren Dunstan, while Kei Watanabe takes the role in the Japanese version. His character in the dub, as well as the title of his debut episode, are based on the film, The Big Lebowski. He speaks like a 1970's rebelling hippy, using terms such as "The Man" and "The Establishment". His Japanese given name is a pun off the name of his key card, "Mokey Mokey".

Belowski plays a Mokey Mokey Deck filled with low-level monsters. His main strategy is to destroy his own fairy-type monsters, thus activating the effect of Mokey Mokey Smackdown and increasing Mokey Mokey's ATK to 3000. 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, but he can easily bypass this with Gift of the Mystical Elf and Mystic Wok

Dimitri, known in Japan as Kagurazaka 「神楽坂」 is a Ra Yellow student who tends to mimic other people's Decks, impersonating the owner of the Deck in almost every detail. After losing a Duel against Syrus with a copy of Crowler's deck, he decided to steal Yugi Muto's Deck from its display case during an exhibition. Despite its possession, Dimitri is defeated by Jaden with the explanation he lacked the same heart that Yugi put into creating his Deck. Apparently, the message doesn't get through, as he then goes on to impersonate Jaden.

In the English dub, Dimitri manages to convince himself that he is actually Yugi, an aspect that was not in the original version. His first appearance (while mimicing Yugi) also mimics the duelist, down to the shape of the bangs that fall over his face and a Millennium Puzzle-esque patch on his shirt.

Dimitri could be a jab to the TCG phenomenon of netdecking and Cookie Cutter decks, as his attempts to win duels by copying the strategies and mannerisms of known professional duelists is very similar.

Dimitri lacks an original deck of his own and is seen playing Crowler's Ancient Gear Deck and Yugi Muto's stolen deck.

He made a cameo in Episode 179 watching Jaden's Graduation ceremony.

In the English dub, 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. Also during his turn, the duel score from the original series is played as opposed to the GX score.

He is voiced by Satoshi Hino in the Japanese version and Dan Green in the dub.

Echo (エコー, Ekō) is Adrian's childhood friend. Echo deeply admires Adrian for putting his younger brother's needs ahead of himself despite the fact that he will always be considered lesser than the true heir to the Gecko family name.

In the dub, she states that Adrian must remain in the alternate dimension to remind him of his goal. As an adult, she is the captain of the Gecko Financial Group's spy submarine. Echo also carries a locket around her neck with a picture of Adrian enclosed in it.

When Jaden and his companions open the portal to the third alternate dimension in search of Jesse, she and Crowler get sucked in. She later meets up Aster and Zane only for Adrian, now hellbent on fulfilling his dream, to show up as well. During Adrian and Aster's duel, Echo is sacrificed by Adrian to the spirit of Exodia the Forbidden One to make it his servant. Despite this, her spirit still loved him. Her spirit later aids Adrian in his duel against when Jesse he's possessed by Yubel, but only ends being used by Yubel to regain its power when the psychopath feeds off the darkness in her soul.

Along with Adrian, her whereabouts are unknown.

During the Genex tournament, Jaden challenges him to a duel, where he realizes that Franz was able to summon Ra without having to decipher the hieratic text and at the same time avoiding god's punishment thanks to a spell card of his own creation called Mound of the Bound Creator. Ultimately, Franz is defeated by Jaden, who uses "Necro Illusion" to use Ra against him, despite neither having the knowledge of Egyptian hieratic text nor Mound of the Bound Creator in play. In the end, Pegasus consoles his defeat and Franz agrees to return to Industrial Illusions as a loyal employee.

Franz plays a Winged Dragon of Ra Deck that focuses on using Ra's special abilites much like Marik did in the Battle City tournament. However, The Winged Dragon of Ra that he holds is a counterfeit designed for research purposes as the real Ra card was destroyed.

He is voiced by Ted Lewis.

(In the Japanese version, Viper says that Pierce “was an angel who came to save his life”, as that same bomb took out his team and would've done him in, as well, had he not spotted the baby.) Years later, Viper gave him a deck of Duel Monsters cards but a sudden gust of wind blew the cards onto the street. Pierce went after them only to get killed by an incoming bus heading in his direction. (To decrease the violence slightly, the English Dub states that Pierce instead came down with a fatal disease.) Since then, Viper had made a deal with a demon arm he found in a later mission, agreeing to help it in exchange for reviving Pierce.

Once Viper and Jaden’s duel is over, the mysterious demon arm takes the plasma form of Pierce and changes Viper’s memory so that he believes Pierce is alive, thus carrying out their "contract".

However, he is defeated with the help of the Ojama Trio. Afterwards, Slade and Jagger leave Duel Academy.
