Thief King Bakura is a villain in the Yu-Gi-Oh! franchise. He is a sadistic thief who will kill anyone to get the Millennium Items. During an unknown point in time, he sealed his soul in the Millennium Ring, along with a shard of the soul of Zorc Necrophades. Both souls then merged together, and Yami Bakura was created. He is the ancient Egyptian incarnate of Ryo Bakura.
He was once a child in the village of thieves, known as Kul Elna. However, Aknadin and his forces arrived and sacrificed everyone there to create the Millennium Items. Bakura was the only survivor, however. He then swore revenge on Pharaoh Aknamkanon, and his son Atem as well. His hatred also created Diabound, his ka.
One day, he was taken to be punished for graverobbing. However, Yami Bakura, from the present, arrived and possessed him (in the manga, he was never possessed, and he did the following events on his own) (this never happened in history), and then escaped. He attacked Atem in the palace with his Diabound, but then fled when Atem summoned an Egyptian god. He later followed Mahado, one of Atem's guardians and the original wielder of the Millennium Ring, into a tomb. They then fought, with Diabound even stronger than last time. He eventually took Mahado's Millennium Ring. The fight ended in a draw when Mahado sacrificed his life to make a very powerful monster, which blasted Bakura away. He was believed to have died.
However, he survived, and raided the palace again. He put an influence on Aknadin's mind. He later fled, with Atem in pursuit. Atem battled with another god, and Bakura battled with an even more powerful Diabound. Bakura won the fight, and Atem was believed to have died. Bakura also acquired the Millennium Puzzle.
Atem survived. He, the Guardians of the Pharaoh, and Bakura, with his Diabound more powerful than ever, battled at Kul Elna, where all the spirits of the villagers of Kul Elna helped Bakura. During the fight, Bakura took one of the guardian's Millennium Items. His Diabound was eventually destroyed, and Bakura was on the verge of death. Yami Bakura then left his body, and said that "he outlived his usefulness" and reduced him to dust. It can be presumed that in history, he died when Diabound was destroyed
(NOTE: ANIME ONLY) Yami Bakura later revived the Thief King. Bakura separated the Pharaoh and his guardians. He then stood in the middle of the village and sacrificed himself to resurrect Zorc Necrophades.

- When Thief King Bakura's soul got sealed in the Millennium Ring, along with a shard of Zorc, he and Zorc merged together and Zorc was created.
