Frostman is a minor antagonist from the Megaman series. He is a Robot Master created by Dr. Wily as a combat robot, initially made out of leftover parts from Clownman. He is being powered by evil energy discovered by Wily who uses it in that generation of Robot Masters, inhabiting a base in a frozen city in Alaska.

As one of the largest Robot Masters, his build is rather bulky with his armor design resembling rounded ice blocks as well as having armor covering much of his face other than his eyes as well as his hands resembling mittens.

He relies more on his strength as well as his ice ability, Ice Wave and generating other ice attacks from vents on his body.
