During the battle, Guts Man will frequently jump around the room and land on the ground. Mega Man won't be harmed but the impact will stun him for a few seconds. Guts Man's main attack is where he throws a huge boulder at Mega Man. The boulder can be broken into smaller pieces. His weakness is the Hyper Bomb.
Guts Man has a brief cameo in Mega Man 7. He appears as a statue in a museum. Ironically, the museum contains statues of other Robot Masters. Whether these statues are copies or the actual Robot Masters is unknown.
Super Smash Bros.
Guts Man's theme can be played in Super Smash Bros. 4 and Super Smash Bros. Ultimate. Also in Super Smash Bros. Ultimate, Guts Man appears as a primary grab type spirit. His spirit battle is a stamina battle against a giant Mega Man with super armor that favors grabbing and throwing the player, causing earthquakes when he lands after jumps.
Guts Man was originally built for construction. He was reprogrammed by Dr. Wily in an attempt to rule the world. As his size suggests, Guts Man has great physical strength. His jumps are strong enough to cause the ground to shake. He is impatient and hot-tempered. However, he is polite and more intelligent than he originally appears. Guts Man is very passionate about his work and he cares deeply about his colleagues' well being, going as far as deviating from the instructions for their safety. The weapon Mega Man gains from him is the Super Arm.
In the Ruby-Spears cartoon, Guts Man seems to have lost his brains.
Mega Man: "Last chance, bot-heads! Give it up or i'll blast you to junkyard city!" Guts Man: Blast THIS, Mega Man! (laughs maniacally as he shrinks Mega Man and Rush with his Shrink Ray.) Mega Man: Sizzling circuits! [Rush barks in terror.] Mega Man: Take this! (Mega Man blasts him with his Mega Buster, but it fails to hurt Guts Man due to his huge size relative to the Blue Bomber.) Guts Man: "Oh! You're killing me! With laughter! But now it's time to give you the boot!" (Guts Man brings his foot down to crush the miniature Mega Man.)
~ Guts Man taunts Mega Man as he shrinks him in The Incredible Shrinking Mega Man
Guts Man is the first Robot Master to suffer an amputation in the Mega Man Ruby-Spears cartoon: getting his legs cut off. This happens to him twice: the first in Proto-Man's game when the Rolling Cutter goes at his legs after being tricked by Mega Man. The second happens for real (in the cartoon) when he and Cut Man start brawling after they get blinded by Mega Man.
