Parasite Mind (ability)

Parasite Mind is a spell used by Yami Bakura to seal a part of his soul within a piece of the Millennium Puzzle.

In the manga, he did this when the Millennium Puzzle was smashed by Mr. Clown. In the anime, he did this when it was smashed by Bandit Keith.

Once Yugi reassembled the Puzzle, Bakura would be able to secretly infiltrate the soul room of the pharaoh.
