Master Hand

Master Hand is a major boss character in Super Smash Bros. Series, though he managed to make a surprise appearance as a mini-boss in Kirby & the Amazing Mirror, granting the rare Smash Copy Ability. He and his counterpart, Crazy Hand, much later appear as the bosses of the penultimate level, and serve as the game's only tag-team styled boss.

Master Hand and Crazy Hand guard the game's final Mirror Shard. Defeating them after the other shards have been gotten allows Kirby to enter the true final level; the Dimension Mirror.

Kirby and the Amazing Mirror
In Kirby & the Amazing Mirror, Master Hand is, together with Crazy Hand, the main boss of level 9, Candy Constellation. In addition, Master Hand appears as a recurring mini-boss that gives the Smash ability to Kirby when eaten. Master Hand's attacks in this game are taken directly from his attacks in the Super Smash Bros. series. Beating the duo gives Kirby the eighth and final Mirror Shard.

As bosses, Master Hand and Crazy Hand retain some of their tag-team based moves seen in Super Smash Bros. Melee.

Physical Appearance
Master Hand is a levitating, animated white glove. He can fly through air and perform many hand-based attacks, such as punches, slaps, grabs, and sweeps. He is portrayed as a right hand, who many seem to consider the manifestation of creative spirit. Master Hand even uses long ranged attacks like shooting bullets and laser beams. He can also make combined attacks with his left-handed counterpart, Crazy Hand. Compared to Crazy hand, Master Hand is more docile.
