History
Thatch was one of the first to try befriending Ace when he had arrived on the ship. Thatch later found the Yami Yami no Mi, 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, leading his former commander, Portgas D. Ace, to hunt him down for revenge.

Trivia

 * Seeing a resemblance between Thatch's name and that of the alias of the real life Blackbeard, Edward Thatch, a fan asked Oda, in a SBS question, if Thatch was based on the real life Blackbeard along with Edward Newgate and Marshall D. Teach. Oda replied to the fan that he indeed based Thatch's name on the real life Blackbeard's alias however the basis is in name only.
