Subspace Bomb
The Subspace Bomb is the primary weapon of the Subspace Army. 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 (with the exception of Galleom, who has a self-sufficient Subspace Bomb in his head). The bomb keeps hold of the ROB's arms, so two ROBs have to be sacrificed for each bomb. Why exactly the bombs were designed to act this way is unknown.
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 Subspace Army members to leave the scene before the explosion.
Since Subspace Bombs have always succeeded in exploding (unless they are damaged before activation), it's unclear whether the countdown can be stopped. It's obvious that the Smashers think so, as they've tried repeatedly (but failed) to remove the ROBs from the sockets or otherwise disable them.
Trophy Info
A weapon that, when it explodes, draws every part of this world within its blast range into 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.
