Cockroach Twin is the name of the two boss enemies at the end of Cossack Stage 3 in Mega Man 4, fought one at a time. These robots were originally made for dome-shaped building maintenance. 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, Ring Boomerang, and charged Pharaoh Shot are the best options against them.
Standard Tactics: The Cockroach Twin walks on the ceiling and shoots energy projectiles.
Weaknesses: Has a weakness to Drill Man's drill missile and Ring Man's ring boomerang. 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.
↑Weapon: Transforming Rockbuster, fires a solar bullet
↑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.
