Square Machine

Square Machine (スクエアーマシン) is a room-like boss, which appears at the end of Cossack Stage 2 in Mega Man 4. It slides like a sliding slot game, doing this at various speeds. At its slowest speed is when it will merge together and Mega Man will need to get inside it to attack it. When it is fully formed, its weak spot, the large flashing red light, will appear. Its weakness is Dust Crusher, although the Wire Adapter can be used as well. Mega Man will have to ride the platforms and dodge the shots as he attacks. It is sort of a bigger and 3-part Picopico-Master.
