Storyline

In "The Subspace Emissary" adventure mode, fighters from across Nintendo's franchises are drawn into conflict when the Subspace Army, led by the Ancient Minister, begins detonating Subspace Bombs that transport parts of the world into an alternate dimension. The fighters must unite against this threat while villains Bowser and Wario attempt to reduce heroes to trophy form using specialized weapons. As the crisis escalates, the true mastermind Tabuu, the embodiment of Subspace who has been controlling Master Hand, is revealed. After Tabuu annihilates the assembled fighters with a devastating attack, King Dedede's fail-safe brooches revive key heroes who then rescue their allies. With Sonic's intervention disrupting Tabuu's power, the united fighters defeat him and restore the consumed areas.
