The Admiral, known as Anacis in the Japanese version, 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 because the microphone feedback obscured Umi no Duel (Duel of the Sea) into Yami no Duel (Duel of Darkness), and 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.
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", which confuses several characters. In the original version, he ends his sentences with cchuu, roughly equating to "I say."
