Master Hand (SSB)
Master Hand is first seen in the opening movie. He places plush doll versions of two random characters on a table, and after carefully positioning objects around them, he counts down from three on his fingers. At the conclusion of the countdown, he snaps his fingers, and the objects, along with the table itself, are changed into a stage resembling Peach's Castle. Soon after, both of the plush dolls come to life.
As a boss
Master Hand is the final boss of the 1P Game. He uses his size and shape to his advantage; he slaps, punches, and flicks the player's character, and receives no knockback from the player's attacks. All of these elements are carried on into his incarnations in later games.
Master Hand cannot be defeated by being launched out of the blast zones. Instead, he has 300 hit points that must be depleted. Once all of his hit points have been depleted, he explodes while floating away into the background, along with the screen fading to white then fade to pitch black.
After the final results screen, a cutscene plays, showing the player's character back into its plush doll form. The camera zooms out, the screen suddently transitions to black, and the sound of a closing door plays.
* Playable characters do not have side special moves in this game.
