Square Machine is the boss from Cossack Stage 2 in Mega Man 4. It is an intruder prevention shutter made to protect important locations, such as the base's large mother computer. It slides around the room in three parts, similar to a slot game, doing so at various speeds. At its slowest speed, it will stop and combine together, and Mega Man must be inside when it closes to attack it. It is not possible to pass by its sturdy walls while closed. When it is fully formed, its weak spot, a large flashing red light on the top, will appear inside, and it will attack with plasma energy. Its weakness is Dust Crusher, although the Wire Adapter can be used as well to deal multiple hits. Mega Man will have to ride the maintenance platforms forgotten inside to reach the weak point and dodge the shots as he attacks.
Standard Tactics: The Square Machine will separate itself and re-attach itself, once it does this it will shoot out energy blast.
Weaknesses: Has a weakness to Dust Man's dust crusher. If its data is corrupted, it will be incapable of coming back.

↑Q. What kind of foods does Rockman like to eat? A. Well… Actually, Rockman’s body is powered by “Solar Energy.” Therefore, he doesn’t really eat, but there are some things that are okay for his consumption… Around the lab, he enjoys drinking “Energy Juice.” As responsibly as he behaves, he’s still a kid after all.
↑Q. The shots that the Rockbuster fires from the hand, what are those exactly? A. The Rockbuster on the arm fires something called a “Solar Bullet”, essentially emitting a compressed form of solar energy that’s very powerful.

↑Q. Do robots like those made by Dr. Wily or Dr. Cossack have self-awareness, and can they talk? And do they run on solar energy like Rockman does? A. I take it you’d like to know if Wily and Cossack’s robots possess “sentience”? Naturally, they each have a “consciousness”, although the level of every “cognitive circuit” embedded inside each one of them varies, producing as many different “personality” types as found in people… Just like you or I, they can speak, and have emotional responses like shyness, or anger, just as we do. Regarding their energy systems, many of them do utilize “solar energy” in some way.
