Twin brother of Stanley Pines. Great uncle (or as they call him, grunkle) to Mabel and Dipper Pines, also twins. He loves the board game D D and more D. Has a metal plate in his skull, this is to avoid Bill Cipher from entering his mind. Lives in Gravity Falls. Has 12 PH.Ds. He knows how to fight, but he's irresponsible and sometimes gets ahead of himself. Extremely smart, and could tutor you (and be qualified to) if he wanted to. A complete nerd. Would die for you. Has six fingers on each hand.
