Cutman is a Robot Master who appeared in the very first Mega Man Game. He attacks using the Rolling Cutter on his head. He throws them like a Boomerang. He is very gullible. After beating him, you obtain his Rolling Cutter.
General Cutman comes from an Alternate Universe, where he was the original DLN-003. After he was implemented an experimental genius chip, his IQ raised to unmatched levels (towering above 200), and started to be perceived by Doctor Wily as too dangerous. During Wily’s attempt to shut the rebellious robot down, Cutman escaped, severing Wily’s arm in the process, and was never heard of until a few years later.
