Crazy Hand

Crazy Hand is a villain in the Super Smash Bros. series, first appearing in 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 being of creation, Crazy Hand embodies a being of destruction.

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.

Super Smash Bros. Melee
Crazy Hand is the main villain in Super Smash Bros. Melee, along with Master Hand and Giga Bowser. Crazy Hand will appear alongside Master Hand in a timed match when the player completes Classic Mode on normal, hard, or very hard under ten 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.

On very hard difficulty, Crazy Hand's drill, rocket punch, jet (only when he attempt to fly into the player), third poke, grab (forward throw), and punch (on grounded players) is a One-hit KO.

Defeating Crazy Hand in Classic Mode earns the player 80000 points, which is mandatory for getting the Diskun trophy.

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

Unlike in Super Smash Bros. Melee, no bonuses are awarded for defeating Crazy Hand in this game. As a result, defeating Crazy Hand in Classic Mode is not mandatory for completing 100% of Super Smash Bros. Brawl.

Super Smash Bros. for Nintendo 3DS/Wii U
Crazy hand retains his role as a final boss in Classic mode in Super Smash Bros. for Nintendo 3DS / Wii U, along with Master Hand. However, rather than having to clear Classic mode in a certain time, Crazy Hand will appear in battle if the player sets the difficulty to 3.0 or higher, and chooses the black path at the end. however, on intensity 8.0 and higher, only the black path will be available, and Crazy hand must be fought. in battle, both Master and Crazy Hand share their stamina. when intensity is set to 5.1 or higher, after losing a portion of stamina, both hands will transform into the Master Core.

In Super Smash Bros. for Wii U, one of the two Special Orders modes is Crazy Orders, which involves using a pass or spending gold to participate in consecutive battles and racking up rewards in a ten minute timespan. After winning at least one battle, the player can choose to fight Crazy Hand in a stamina match. Depending on how many tickets have been cleared cleared, additional opponents may appear alongside Crazy Hand, including Master Hand. Crazy Hand occasionally drops chests when hit, and when defeated, the player gets to keep all rewards accumulated.
