Commando Man is a Robot Master from the 2010 game Mega Man 10. He attacks by stunning the player with his ground pounds and is also able to shoot Commando Bombs that home in on the player.
In MKF, Commando Man is one of the eight Portal Masters found in the Wily Portal Chamber featured in Wily Citadel, which is the final level of World 3. The player must defeat all eight "Portal Masters", including Commando Man, without dying, or be forced to fight all of them again (although an extra life is provided beforehand to prevent the player from running out of lives). After Commando Man and the other Portal Masters have been defeated, a path to the final checkpoint will open up. Inside the player will enter one last teleporter, which will transport them to the boss room and the final battle against Dr. Wily.
