A Subspace Bomb being primed for detonation in the Midair Stadium.

The Subspace Bomb is the primary weapon of the Subspace Army. These sinister weapons make their debut when the ROB Leader (then known as the Ancient Minister) stages a raid against his will against the Midair Stadium. When detonated, it removes the surrounding area from the world and deposits it into Subspace, leaving a dark void behind. The effect is additive; a larger area can be affected by causing multiple bombs to go off at once. Each bomb requires two Robotic Operating Buddies to function. The bomb keeps hold of the R.O.B.s' arms, so two R.O.B.s have to be sacrificed for each bomb. Why exactly the bombs were designed to act this way is unknown, although it is possible that they require power from the R.O.B.s to function. The way R.O.B's sacrifice themselves makes The Ancient Minister aggrieved by it.

Subspace Bombs were designed and built on the Isle of Ancients. As such, there is a large factory on the island, able to store dozens of bombs at once.

The average Subspace Bomb has a detonation timer of three minutes. Presumably, this allows Fighters to leave the scene before the explosion. Since Subspace Bombs have always succeeded in exploding (unless they are damaged before activation), it is unclear whether the countdown can be stopped. The Fighters of the World of Trophies repeatedly attempt to stop the bombs from detonating but fail each time.

Galleom has a self-sufficient Subspace Bomb embedded in his head. This bomb does not require R.O.B.s (presumably drawing power from Galleom's body instead) and had a detonation timer of fifteen seconds. Since Galleom likely tried to blow up the bomb as soon as possible, it can be assumed it needed fifteen seconds to charge. Galleom used this bomb once it was defeated twice in quick succession, attempting to take revenge on Lucas and Pokémon Trainer as it blasted into the sky. The two managed to escape, and the bomb dealt minimal damage to the surrounding area, drawing Wario's trophy into subspace instead.

Subspace Bombs were surpassed in functionality near the end of the Subspace Emissary by the Subspace Gunship. The Gunship's primary weapon has the same effect as a Subspace Bomb, but can be launched from a great distance and can be used repeatedly without the assistance of R.O.B.s. Once the Gunship was complete, all remaining Subspace Bombs were detonated to open up a large enough hole in space for the Gunship to be deployed.

Trophy Info[]

Subspace Bomb Trophy

Subspace Bomb Trophy is one of the many trophies gained on Super Smash Bros. Brawl. The trophy is under the Subspace Emissary category if one searches by game title or under enemies if one searches otherwise. It is unlocked by completing Boss Battles on easy difficulty.

A weapon that, when it explodes, draws every part of this world within its blast range into the world of Subspace. The areas drawn into Subspace this way float about in bubbles as individual colonies. To detonate a bomb, two R.O.B.s must be destroyed in the process. The Ancient Minister is bitterly aggrieved by this fact.


  • At the end cutscene when the world returns, there is an error: the ruins lack the hole that Galleom fell into.
  • Ike is the only character who successfully disarms a Subspace Bomb.
