Crazy Hand

Crazy Hand is a large, disembodied, gloved left hand who usually fights alongside Master Hand in the higher difficulty settings of Classic Mode. He first appears in Super Smash Bros. Melee.

Unlike Master Hand, who embodies a being of creation, Crazy Hand embodies a being of destruction. Crazy Hand moves erratically and has more attacks, many of which have side effects, such as the Lip's Stick flower. Crazy Hand attacks more frequently, giving fewer opportunities to hit. Crazy Hand has the same voice actor as Master Hand in each of their appearances.

Super Smash Bros. Melee
In Super Smash Bros. Melee, Crazy Hand appears alongside Master Hand in a timed match when the player completes Classic on Normal, Hard, or Very Hard under ten minutes, and does not use a continue. Crazy Hand also fights alongside Master Hand in the event match, Lv. 50: Final Destination Match.

On Very Hard difficulty, Crazy Hand's drill, rocket punch, jet (only when he attempts to fly into the player), third poke, grab (forward throw), and punch (on grounded players) are all 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. Although he is absent from The Subspace Emissary, Crazy Hand appears in Boss Battles mode with the standard Emissary boss health bar. Crazy is the only boss who does not need to be fought in order to unlock Boss Battles mode.

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 100% completion.

Super Smash Bros. for Nintendo 3DS
Crazy Hand retains his role as a final boss in Classic mode in Super Smash Bros. for Nintendo 3DS, along with Master Hand. However, rather than having to clear Classic mode within a certain time, Crazy Hand will appear in battle if the player sets the intensity 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 Hand and Crazy Hand share their stamina. When the intensity is set to 5.1 or higher, after losing a portion of stamina, Crazy Hand will be engulfed in flames and exit the battle, while Master Hand will transform into the Master Core.

Super Smash Bros. for Wii U
Crazy Hand is also a final boss in Super Smash Bros. for Wii U's Classic mode. However, unlike in Super Smash Bros. for Nintendo 3DS, players will be forced to fight Crazy Hand, along with Master Hand, at intensity 3.0 or higher; this also means that at intensities 5.1 and above, Master Core must be fought as well. Also, 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 time span. 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.

Crazy Hand also has a new move, known as the Void. He rips open some part of the air and can suck the players into a void, which deal damage after the players are launched out. The only ways to avoid the Void are using shield, and doing continuous rolls.

Super Smash Bros. Ultimate
Crazy Hand reappears in Super Smash Bros. Ultimate, where he returns as a boss in Classic mode, as well as in Adventure Mode: World of Light. In Classic mode, Crazy Hand appears alongside Master Hand if the player reaches Intensity 7.0 or higher, though some fighters are assigned to fight the former alone. In World of Light, Dharkon creates an army of clones of the original Crazy Hand, some of whom create obstacles for the player, and are fought as well. If the player meets the requirements for the game's true ending, Crazy Hand and Master Hand help the player by opening up a hole in space for them to enter, to defeat Galeem's and Dharkon's clones and for the final battle with both entities.

Crazy Hand also appears as an Ace-class Neutral-type primary spirit. It allows three support slots and is obtainable by winning the last battle against Crazy Hand in World of Light. It is among the most powerful spirits in the game.
