Master Hand is a character and boss in the Super Smash Bros. series. He first appeared in Super Smash Bros. as the main boss of the game, and had the same role in the sequel, Super Smash Bros. Melee, met in Final Destination. He slightly resembles Mario's gloves in Super Smash Bros. He also made a cameo appearance as one of the mini-bosses in Kirby & the Amazing Mirror. Master Hand has appeared in many other Nintendo games, but his appearance is usually very worthless, like in Kirby's Adventure , after getting a Game Over. In Super Smash Bros. Melee and onward, Crazy Hand will fight along side Master Hand if certain conditions are met. In Super Smash Bros. for Nintendo 3DS/Wii U, an entity called the Master Core appears.
Master Hand also loves to create, and it is still unknown if he created the Fighting Wire Frames, the Polygon Team, the Alloy Team, Giga Bowser, and Crazy Hand. Master Hand has no hosting body, but is said to have one that links him to Crazy Hand. He also makes an appearance in Super Smash Bros. where he turns the dolls (which are the characters in the game) into amazing fighters.
Master Hand can only be played in Super Smash Bros. Ultimate legitimately. The only other way to play as Master Hand is to use a cheating device, however, in Melee, he is also playable through a glitch. If the player forces a "no contest" in Melee, his name will appear as Sheik, but no character will be displayed.
Master Hand is featured in Super Smash Bros. Brawl. In the Subspace Emissary storyline, Master Hand is seen controlled by Tabuu. After the strings were severed, Master Hand and Ganondorf attempt to fight Tabuu, but are quickly defeated.
