Crazy Hand (クレイジーハンド Kureijī Hando) is a villain in the Super Smash Bros. series, first appearing in the game Super Smash Bros. Melee. Like his right-handed counterpart, Master Hand, he is a large, disembodied, gloved hand, though he is a left hand instead of a right hand.
Unlike Master Hand, who embodies a creation, Crazy Hand embodies a being of destruction. Crazy Hand is voiced by Dean Harrington (Melee), Pat Cashman (Brawl), and Xander Mobus (3DS / Wii U), who also voiced the announcer of the respective game.
Crazy Hand is a more dangerous foe than Master Hand, since he has more attacks, and many of his attacks also have side effects, such as the Lip's Stick flower. Crazy Hand also attacks more frequently, giving fewer opportunities to hit, which makes the battle in Classic Mode harder because the fight with him and Master Hand is timed.
