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. 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 Mega Buster are the best options against them.
