Tabuu

Tabuu is the main antagonist of the video game Super Smash Bros. Brawl, the final boss of the game's story mode, The Subspace Emissary. He is the leader of the Subspace Army and is bent on destroying the entire Smash universe.

Description
Tabuu is considered to be the leader of the Subspace Army. He is an almighty god-like being that takes on the shape of a human being, but appears to be made of glowing blue energy. He sports an epic set of wings similar to those of a butterfly, but with a more sporadic shape and pattern.

Story
Before the events of The Subspace Emissary, Tabuu arrived on the Island of the Ancients where the ROBs lived, causing conflict among them. After enslaving the ROBs, Tabuu had the robots build a series of Subspace Bombs which would later be deployed in various areas throughout the World of Trophies.

Later, Tabuu discovered that Mr. Game & Watch had contracted Shadow Bugs and captured him, forcing him to use the strange substance to create a seemingly unlimited number of minions for him, thus building the Subspace Army. He then took control of Master Hand, and through him, recruited the villains Ganondorf, Bowser and Wario. These three were sent to hunt down any fighters that would stand in the way of Tabuu's plans, while remaining unaware of Tabuu's existence. However, King Dedede learned the truth about Tabuu and began interfering with his plans.

Much later in the story, after most of the heroes have rallied together to fight the Subspace menace, Ganondorf betrays Bowser by blasting him with a Dark Cannon. He then goes to greet Master Hand, only to find that Master Hand has been puppeteered by Tabuu. Enraged, he charges a futile attack at Tabuu, who effortlessly knocks him away and causes him to land on Master Hand, freeing him from Tabuu's control (and turning Ganondorf into a trophy in the process). Master Hand then attacks Tabuu, but is effortlessly defeated. Tabuu then unleashes his Off Waves, turning all of the approaching heroes into trophies at once.

With the heroes already defeated, Tabuu created the Great Maze from the various locations that had been engulfed by the Subspace Bombs. Thanks to the medallions that King Dedede used for some emergency, he, Luigi and Ness infiltrated Subspace. They confronted and defeated Bowser, then restored him so that he could join their team once they informed him of what had happened to Master Hand. Kirby would also be revived by one of Dedede's brooches that he had swallowed earlier on in the adventure. Together, they would venture into the Great Maze and revive the other fallen heroes.

Shortly after passing through the Great Maze, the heroes confronted Tabuu once more. Tabuu once again tried to defeat them using his Off Waves, but he was suddenly struck by a blue blur that shattered one of his wings, reducing his power. Sonic the Hedgehog had entered the fray at the last minute and joined with the other heroes as they fought to take down Tabuu. After a grueling battle, Tabuu was defeated and the areas consumed by Subspace were restored and the Isle of the Ancients disappeared afterwards because of the effect of so many Subspace Bombs going off at once (commanded by Ganondorf so Tabuu could get a Subspace Gunship into the world) making it impossible for the island to escape Subspace. A luminous cross is left in its place.

Tabuu's true fate is unknown - he is last seen contorting in pain shortly before the Great Maze was restored to its original places and forms - though it is likely he was destroyed.
