Bivin, known as Takeshi Kameta or Slider Kameta in the Japanese version, is a character appearing in the Tag Force series.
In the first Tag Force game, he is seen as an ordinary Obelisk Blue student. Upon acquiring his Deck Recipe, he also gifts the player with a "Freed the Matchless General" card. Personality-wise, he doesn't seem to be confident, implying that compared to other duelists, he could be relatively easy.
In Yu-Gi-Oh! GX Tag Force, Bivin plays a Deck called "Overage Turtle", which contains a large variety of "Turtle" monsters, supported by the various cards of the "Trap Hole" series.
