The Bomb is an enemy from Final Fantasy II. Bombs can be difficult to defeat without triggering their Self-Destruct VII attack. To avoid this attack, the player should attempt a one-hit KO, using a high level Fire or Thunder spell.
Oddly, Bombs are weakest against Fire. In most games, casting Fire on a Bomb either does minimal damage or heals it. This could be due in part to its explosive nature; perhaps, using a Fire-elemental spell would ignite it faster.
