Whilst Metal Man is a quick and efficient worker, he possesses a dry wit- having something of a reputation amongst his colleagues for being sarcastic and often untrustworthy. Directly relating to his skill with throwing his Blades, he enjoys playing with Flying Discs in his spare time, but dislikes it when dogs get in his way by catching them. When Dr. Light saw Metal Man for the first time, he remarked that he was "the dentist of the future".
Metal Man is infamous among players for being killed with one or two hits from his own weapon when battling him for the second time in Mega Man 2, which was added as a secret trick to make the game more captivating. Also, a glitch in the Game Boy game Mega Man II can leave Metal Man stuck in the walls, making him harmless.
