The Trap is an enemy in Crisis Core -Final Fantasy VII-.
Trap, like all Bomb-type enemies, can increase their size with "It's bigger!" up to twice before it can use Self-Destruct. Otherwise, it will attack with Fira. They are not super difficult to defeat, but be wary of being in the blast radius of Self-Destruct. If they use Self-Destruct, no rewards are given from that particular Trap.
