Crazy Hand is one of the overseers of the Nintendo Megaverse, accompanied by his “brother”, Master Hand. Whereas Master Hand defends the order of the Megaverse, Crazy Hand lords over chaos, and has covertly aided many of the villains of the various universes, although he is careful never to surpass the order caused by his brother. In his rare dealings with mortal beings, Crazy Hand comes across as insane and nonsensical, but he truly has a deep understanding of his role, and always takes it very seriously.
Along with his brother, Crazy Hand was tasked with assembling a team to take down the inter-dimensional conqueror, Doctor Doom. To this end, he was responsible for gathering the Super Smash Bros., and was key in gaining the aid of several villains for this cause.
As a cosmic force, Crazy Hand is capable of near-godlike acts, including (but not limited to) creation of inter-dimensional portals, producing explosives out of his palm, firing lasers or explosive, bullet-like projectiles out of his fingers, creating darkness, electricity, or intense cold around his form, or propelling himself with rocket-like force. In addition, Crazy Hand has a chaotic mind, and his actions are frequently unpredictable.
Although Crazy Hand possesses major durability, and is a true immortal, his form can be temporarily destroyed if it sustains enough damage. In addition, he can be killed if the Nintendo Megaverse is destroyed.
"Talk to me!"
"We gonna do something?"
"You know where I am!"
"Don't do anything I wouldn't do!"
"You'd have to be insane to be this crazy!"
"To infinity and...wait, is that copyrighted?"
