Tabuu is the final boss of the Subspace Emissary mode of Super Smash Bros. Brawl. He has a transparent humanoid figure, with a pair of red eyes and a strange object inside of him. He is the "embodiment of Subspace" and created the Subspace Army. His name is a corruption of the word "taboo", which means unacceptable or improper by society's terms. The spelling of his name is derived from a katakana transcription of the word, romanized for English language releases.
Tabuu is the embodiment of Subspace. Observing the World of Trophies, he has the desire to cut the world into pieces and bring it into Subspace. However, because he cannot leave Subspace, he is forced to form an army in order to do this. After studying the world and its inhabitants, Tabuu takes control of Master Hand, the master of the world, and using Master Hand recruits Bowser, Wario, and Ganondorf. He also notes the peculiar structure of Mr. Game & Watch, and uses him to create Shadow Bugs, which form the soldiers for the Subspace Army.
Tabuu also takes notice of Meta Knight's ship, the Halberd, to use as transportation for his army, and is successfully able to attack and capture the ship. In addition, he learns of the advanced technology on the Isle of Ancients and conquers the island, using the Robots to build weapons such as Subspace Bombs in order to take parts of the world into Subspace, the Master Robot joining him in the process.
The Subspace Emissary
After suffering a humiliating defeat, Ganondorf and Bowser enter Subspace to seek out Master Hand. Planning to take control of the army, Ganondorf betrays Bowser before approaching Master Hand and bowing before him. Just as Ganondorf prepares to attack Master Hand, Tabuu reveals himself. Ganondorf tries to free Master Hand by attacking Tabuu, but he easily overpowers Ganondorf, turning him into a trophy with a single attack. Ganondorf falls on Master Hand with enough force to sever Tabuu's strings of light, freeing Master Hand. The weakened Master Hand attempts to destroy Tabuu, but Tabuu easily reflects his attack, stunning Master Hand.
The heroes later arrive and confront Tabuu, who spreads his wings and releases his ultimate attack, the Off Waves, instantly transforming every fighter to their trophy form. He then puts the pieces of the world taken from the World of Trophies to create The Great Maze. However, Luigi, King Dedede, and Ness return back to their original states thanks to the brooches Dedede had invented. The three travel to Subspace and return the heroes to their original forms.
After making their way through the Great Maze, the heroes arrive at Tabuu's lair for the final showdown. Tabuu prepares to use his Off Waves again, but Sonic the Hedgehog appears and attacks Tabuu, shattering his wings and preventing him from transforming the group into trophies. The heroes then face Tabuu in the final battle. After he is defeated all the pieces of the world taken into subspace and all the characters are returned to their proper locations.
