Tabuu

Intro The leader of the Subspace Army and the final boss. He is a powerful godlike entity who embodies the dimension of Subspace. He uses the Subspace Bombs to send entire locations to his dimension, where he absorbs their power to increase his own, pursuing his plan to conquer and subjugate the universe. His name is a corruption of the word taboo, referring to something forbidden. Tabuu is the embodiment of Subspace who plotted to transport areas of the World of Trophies into Subspace for his world. However, he himself cannot leave Subspace, which is why he created the Subspace Army to act in his stead. Tabuu took over the Isle of the Ancients, the home of the R.O.B.s and forced them to serve him under the threat of annihilation. Tabuu first discovered that Mr. Game & Watch had Shadow Bugs in him and captured him to harness the power and thus the Subspace Army was born. Tabuu studied and took control of the master of the world, Master Hand, and used his powers to control him like a puppet.
