Rattrap is an enemy from Mega Man ZX. It is a ground-mounted cannon with two doors on top that only open when releasing a small rat robot, its only method of attack. The cannon itself is invulnerable until the doors open, but the rat robots will self-destruct after a set amount of time if not destroyed before that. Rattraps appear in Area L Research Lab.

New Rattrap

New Rattrap, known as New SO9 (ニューSO9) in Japan, is a new version of Rattrap that appears in Mega Man ZX Advent. These Mechaniloid mice tend to come in huge numbers. With so many of them, they are sometimes prone to short-circuit and blow up. They appear in the Bio Lab and can be summoned by Hedgeshock the Erinaceroid.
