Subspace (Super Smash Bros. Brawl)
From Mariopedia, a wiki on Mario, Yoshi, Wario, Donkey Kong, Super Smash Bros., and more!
Subspace is an entity found in the Subspace Emissary in Super Smash Bros. Brawl. However, it is more comparable to The Void, than being an actual place. In The Subspace Emissary, the Subspace Army uses Subspace Bombs to drag a stadium into Subspace. Each time a bomb detonates, a certain part of the world is destroyed. It is unknown exactly when this will occur in the actual game, however.
