Gecko Moria

Gecko Moria (ゲッコー･モリア, Gekko Moria) is a member of the Shichibukai who currently resides on the floating island, Thriller Bark. He is one of the main major antagonists of the current arc. He is the one who stole Brook's, and various other beings' shadows, and seems to be somehow connected to the ghosts on Thriller Bark. The loss of a being's shadow causes them to be vaporized if they come in contact with sunlight. His former bounty was higher than Luffy's 300 million bounty according to Robin.

He is later revealed to be a giant and the entire island of Thriller Bark is his ship.
