Tabuu

Taboo (also known as Tabuu) is the final boss in the Subspace Emissary mode of Super Smash Bros. Brawl. He resembles the characters from the movie Tron and he will have two forms, the second one including an enormus ethereal wings.

He comes from the game Taboo: The Sixth Sense, a tarot simulator game released for the NES in 1988. This game was developed by Rare, the same studio who create the Donkey Kong Country series lately.
