Guts Man is a civil engineering Robot Master. He was created by Dr. Light to work alongside Bomb Man for the purpose of land reclamation and construction. While he can be hot-tempered, impatient and unreasonable, he is passionate about his line of work, is more intelligent than his appearance and mannerisms would suggest, and cares for the well-being of his colleagues and his robotic brothers, acting as an older brother. His Super Arm weapon can help carry heavy things, and also throw enemies.
