The Subspace Bomb is a weapon used by the subspace army in Super Smash Bros Brawl's adventure mode, Subspace Emissary. The subspace bomb appears a ball with a cross on it with 2 slots on either side. When 2 R.O.Bs stick their arms into the hole's the bomb opens and activates a timer. When the timer runs out the bombs creates a huge explosion which sucks everything in the blast radius into Subspace. The 2 R.O.Bs must be sacrificed to detonate the bomb. Ike is the only known character to be able to have destroyed a Subspace bomb.
