The main antagonist and final boss of Super Smash Bros.'s Subspace Emissary Mode, Tabuu is the mastermind behind the events of the Subspace Emissary and has always been operating behind the scenes in the dimension of Subspace while his followers, the Subspace Army, led by the Ancient Minister outside of Subspace itself (who is in truth a Family Computer Robot beneath the cloaks), carry out all the work for him sending the pieces of the World of Trophies to Subspace for him using Subspace Bombs to do so. Tabuu is known for his "Off Waves", his attack where he unleashes three circular energy waves from his wings that can instantly knock the player off the arena on high difficulties, also known as his "Red Rings of Doom" attack.
