Yu-Gi-Oh! GX minor characters

Admiral
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. 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. 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.

Voice/Mannerisms
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”.

Deck
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.

Alice
Alice (アリス, Arisu) is the spirit of a doll possessed by the vengeful Doll Chimera card. Her character is based on the title character of Alice's Adventures in Wonderland. In the English version, Alice is voiced by Priscilla Everett, while Kumiko Nishihara takes the role in the Japanese version.

When Jaden returns from Domino City, Winged Kuriboh detects that Alice is a stranger. Alice is nice to the rest of the Slifers, but during the night, Tyranno disappears. Jaden and his friends discover that Alice has kidnapped him and is using him as hostage to challenge other duelists, claiming she posed as a transfer student of Slifer Red in order to seek out victims to plunge into darkness. She justifies that all happiness is an illusion and she's here to erase that false happiness. In the Japanese version, Alice wants to crush all the light of hope from duelists. She challenges Jaden to "duel of despair" in which he replies it will be a "duel of hope".

As the duel progresses, Alice's anger and bitterness slowly fades away to Jaden's cheery personality and the honesty of his happiness when he duels. She starts to realize dueling is actually fun. It is then she reveals that she is in fact a doll spirit. In the past, she watched a bunch of Obelisk Blue students duel. When one kid in particular lost, he blamed his loss on his card Doll Chimera and ripped it in half, calling it useless trash. The anger and pain of the card seeped into her and ever since, Alice disliked duelists for she had the conception they were all heartless creatures. She was finally quelled when Jaden destroyed Doll Chimera, thus freeing her from its influence. Upon losing the duel, Alice turns back into her doll form and thanks Jaden for setting her free.

Deck
Alice uses a Doll Deck, composed of "Doll Part" 「ドールパーツ」 monsters which strengthen Doll Chimera as the number of copies in her Graveyard grows.

Beauregard and Brier
Beauregard and Brier, known in the Japanese version as Ohara (大原 Ōhara) and Kohara (小原 Kohara), are Ra Yellow duelists. Beauregard is a heavy set duelist who aspires to be a game designer while Brier is a very skilled duelist but is shy in crowds. They teamed up where Beauregard played the part of the duelist "Duel Giant," with Brier giave him instructions via a radio headset during duels. The duo did this to win cards by bullying Obelisk Blue students into unauthorized Ante Duels. Eventually, word gets around to Vellian Crowler who then "hires" Jaden to defeat the Duel Giant (with hopes that he'll be able to evict him from the academy if he fails.) At midnight, Jaden and his friends meets up with the Duel Giant and challenges him to a game. Eventually, he discovers Brier and Beauregard's trick and convinces the two to battle him out in the open in exchange for not turning them in.

In the English version, they are voiced by Dan Green and Pete Zarustica, while Holly Kaneko and Chieko Higuchi take the roles in the Japanese version.

Decks
When Beauregard and Brier duels along side each other as the "Duel Giant", they use a Goblin Deck, which includes high-ATK strength creatures such as Giant Orc that can have its drawback removed by the Union Monster Second Goblin.

Belowski
Belowski, known in Japan as Motegi Mokeo (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.

Character biography
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.

Voice/Mannerisms
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".

Deck
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.

Dimitri
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 Mutou'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. 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.

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.

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

(Note: 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.)

Echo
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. She sees that he is fit to rule the world as a king, though his responsibilities to his sibling prevent him from doing so. 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 posessed by the demon arm, 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.

In the English dubs, Echo is voiced by Priscilla Everett, while Yuki Nakao takes the role in the Japanese version.

Her name is derived from the name of the nymph Echo in Greek mythology.

 * Short Circuit

Franz
Franz (フランツ, Furantsu) is one of Pegasus' top card designers from Industrial Illusions whose jealous of Chumley's talents, seeing as his own designs are looked down upon for they are too powerful for gameplay. He manipulates the only remaining copy of The Winged Dragon of Ra stolen from the company. 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 aganist 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.

Deck
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.
