Crazy Hand

Crazy Hand is Master Hand's left hand counterpart in the Super Smash Bros. series introduced in Super Smash Bros. Melee. He acts as one of the two final bosses of Adventure in Super Smash Flash, alongside Master Hand.

Character description
Like with Master Hand, Crazy Hand's origins are very mysterious. He looks exactly the same as Master Hand (apart from being a left hand), but he is more destructive and chaotic in general. While Master Hand's movements are very mature and easygoing, Crazy Hand moves in dysfunctional and erratic ways. He is impulsive and consumed with a hollow feeling which comes from destroying one’s own creations.

Crazy Hand also appears in the Game Boy Advance game Kirby & The Amazing Mirror alongside Master Hand, as the boss of Candy Constellation. However, the concept of the Hands may have come from a boss called Wham Bam Rock from Kirby Super Star and Kirby Super Star Ultra, who attacked Kirby with a stone hand that used different slaps, pokes, and grabs.

In Super Smash Flash
In Super Smash Flash, Crazy Hand appears exclusively as the final boss of Adventure alongside Master Hand. Like Master Hand, Crazy Hand cannot be defeated by normal means; instead of damage, he has "hit points" (HP), the amount of which is altered based on the difficulty (for example, he only has 150 HP when fought on Very Easy mode) and must be depleted. Once 0 HP is reached for both bosses, they explode into the background and the mode is beaten. To fight him, the player must to clear this mode on any difficulty and deplete Master Hand's HP to the halfway point, and then Crazy Hand will appear to aid Master Hand. The player must then proceed to defeat both bosses.

Unlike in the official Super Smash Bros. games, both Hands do not use conjunction attacks with each other, such as claps or double punches, and attack exactly the same, only that Crazy Hand is a bit faster than Master Hand.

In Super Smash Flash 2
Crazy Hand is currently absent in Super Smash Flash 2 as of the Beta version. The second Master Hand in event #51: ????? is meant to represent him.
