Ultimate Chimera

Ultimate Chimera is a boss character in the game, Mother 3, and a gimmick in Super Smash Bros. Brawl. It only appears on the New Pork City stage of the game, where it will randomly appear anywhere across the stage, and start attacking the players. The creature is invincible, and any attempts at damaging it or knocking it away will fail. If the Ultimate Chimera manages to hit any of the players on the stage, it will instantly KO that player, sending them flying across the stage.
