Bakura is a new transfer student into Yugi Mutou's high school class. The normal Bakura is a kind-hearted person who encourages Yugi and Jounouchi through their duels in Duelist Kingdom. The bad part to Bakura is that he is the wielder of another Millennium item. He wields the Millennium Ring, contrary to Yugi's Millenium Puzzle, Pegasus' Millennium Eye, and Malik's Millennium Rod.
Bakura's Millenium Ring contains a very evil spirit that takes control of him and has very dark ambitions that rival even Yami Malik's ambitions. The Millennium Ring has the power to locate other millennium items with its various pointers. Yami Bakura is first seen when Yugi is challenged to a Game of Darkness (English: Shadow Game) by Bakura in the Duelist Kingdom. Bakura entraps normal Yugi, Honda (English: Tristan), Jounouchi (English: Joey), and Anzu's (English: Tea) souls into their favorite cards inserted in Yugi's deck. Yami Bakura then proceeded to claim the Millennium Puzzle in which Yami Yugi stopped him. Yami Yugi won his duel versus Yami Bakura with a quick use of his shadow powers. He switched normal Bakura's soul with the soul of Yami Bakura in Bakura's Change of Heart card to send Yami Bakura to the graveyard.
At the very end of Duelist Kingdom, Yami Bakura makes a return appearance by "disposing" of Pegasus and taking his Millennium Eye. When Battle City rolls around, Bakura is still with the group, but Yami Bakura shows his true intentions of taking the Millennium Puzzle. He duels Yami Yugi again in a rematch, during Battle City. Yami Bakura took an early advantage using a combo from his Occult Deck, involving the Dark Necrophia (English name: Unknown) and Quija Board.
As long as Dark Necrophia was in the graveyard, Yugi had 5 turns left in the duel to finish it, otherwise he would lose. If all 5 turns of the Quija Board are passed, spelling D-E-A-T-H, Yugi would automatically lose. (Note: In the CCG it is different, you need 5 magic cards to assemble to win.) With a quick combo, and one turn left, Yugi manages to summon the god card, Osiris. Bakura gets hit with Osiris' Thunder Force attack and falls unconscious. Currently in the magna, after this duel, Yami Bakura faced Yami Malik in one final duel. The game penalty to the loser would be that whoever lost would disappear forever. As it seemed, Bakura loses, via Malik's summoning of Ra, and the revealing of Ra's final ability, the Hand Phoenix. This allows Malik to sacrifice all his LP but 1, and transfer all LP sacrificed to Ra's attack and defense stats. As Ra uses his Breath Cannon to wipe out Bakura, Yami Bakura says, "I may have lost, but I will definitely be back, and I will kill you. This is because I AM the darkness."
Bakura has not reappeared in the series, manga or anime, since that duel. Bakura uses an Occult deck, which is a mixture of dark main type monsters, and fiend monsters. He is pretty good at dueling with this in his Yami form. His main combo is the Dark Necrophia / Ouija Board combo, but if not he has some strong back-up monsters lying in wait.
