Master Hand

Master Hand (or as known as The Hand) is a right hand-like entity who acts as the creator of the Super Smash Bros. universe and is also the owner and top collector of the World of Trophies. He is the main antagonist of the Super Smash Bros series. It is assumed that Master Hand is the representation of the child who owns the trophies collected throughout the game. Due to his position as a boss, Master Hand is only playable in the games through hacking (save for Super Smash Bros. Ultimate), 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. He has been a boss on all Super Smash Bros. games.

In Super Smash Bros. for Nintendo 3DS/Wii U, a huge black-like substance called Swarm emerges from Master Hand when challenging Master Hand and Crazy Hand on 5.1 intensity or higher.
