Thatch

Thatch (サッチ, Sacchi?) was the fourth division commander of the Whitebeard Pirates. Thatch was one of the first to try befriending Ace when he had arrived on the ship. Ace responded cynically, and questioned why he is not being held with shackles while on board of the Moby Dick, Thatch merely gave an amused look, as though he believes that was unnecessary. Thatch later found the Dark-Dark Fruit, the Devil Fruit that Blackbeard was after for a long time. This Devil Fruit was the very reason that Blackbeard joined the Whitebeard Pirates, so he killed Thatch and ran off with it, leaving his former commander, Ace, to hunt him down for revenge. All that is known about Thatch's fighting abilities, was that he was a swordsman.
