Master Hand

Master Hand  is a right hand-like entity who acts as the creator of the Super Smash Bros. universe and is also the creator of the World of Trophies. He is the main antagonist of the Super Smash Bros series. He is only playable in the games through hacking, but in Melee, a glitch exists that makes him playable. Master Hand's origins are unknown and his and Crazy Hand's purposes are undiscovered. However, Master Hand and Crazy Hand seem to respectively represent creation and destruction.
