Cockroach Twin

Cockroach Twin (コックローチツイン) is the name of the two boss enemies at the end of Cossack Stage 3 in Mega Man 4, fought one at a time. The first one stays on the ceiling, and the second walks around the whole room in a clockwise pattern. The room has spikes on the bottom, so the player must be careful when jumping. Drill Bomb and charged Pharaoh Shot are the best options against them. If you use Flash Stopper to finish them, you won't be able to leave and will have to die or reset. If you use Wire to finish them, (use it when they are on the the ceiling) you will be stuck there until you drop.
