William Murderface is Dethklok's bassist. He plays a Gibson Thunderbird Studio 5-string. He has brown hair, lime green eyes, a heavy lateral lisp and a diastema. Murderface's father killed his wife with a chainsaw before turning it upon himself in front of Murderface in a grisly murder-suicide. Murderface is "a self-hating bass player who's always trying to act like he's more important than he is," in part because his bass playing is usually mixed out completely.
