Level 49 - Master Hand

 

Masutā Hando) is a 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 final boss of the 1P Game in Super Smash Bros., the final boss of the Classic Mode in Super Smash Bros. Melee, and the final boss of Classic mode in Super Smash Bros. Brawl. 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 purpose is undiscovered, but both hands seem to be in a dualistic conflict of create and destroy. As he is the only character originating from the series that has appeared in all the games, he can be considered to be the main character of the entire series.
