Crazy Hand

First appearing in Super Smash Bros. Melee, Crazy Hand is a villain in the Super Smash Bros. series. Like its right-handed counterpart, Master Hand, it is a large, disembodied, gloved hand, though it is a left hand instead of a right hand. Crazy Hand also twitches its fingers in odd angles at the joints, in a very unnatural way. Unlike Master Hand, who embodies a being of creation, Crazy Hand embodies a being of destruction.

Crazy Hand is a more dangerous foe than Master Hand since it has more attacks, and many of its 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 it and Master Hand is timed.

Super Smash Bros. Series
Crazy Hand is the main villain in Super Smash Bros. Melee along with Master Hand and Giga Bowser. Crazy Hand will appear alongside the Master Hand in a timed match when the player completes Classic Mode on normal, hard or very hard under 10 minutes and does not use a continue. In addition, Crazy Hand is also fought in the 50th event match alongside Master Hand. This match is not timed.

In Super Smash Bros. Brawl, it appears under the same circumstances in Classic Mode as it does in Melee. Though it is absent from the Subspace Emissary, Crazy Hand appears in Boss Battles Mode with the standard Emissary boss health bar.

Brawl
''A seeming manifestation of the destructive spirit in direct contrast to Master Hand, who is the manifestation of the creative spirit. Crazy Hand appears out of nowhere when Master Hand's power begins to ebb. His repeated attacks evoke the bizarre. Those who must face Master Hand and Crazy Hand at the same time face a long and painful battle to the death.''

Trivia

 * In Kirby and the Amazing Mirror, Crazy Hand appears as a boss along with Master Hand. Once defeated, Kirby can eat him and become Smash Kirby (He can use all of Kirby's special attacks from Melee.)
