Dompan

Dompan (ドンパン), named Firework Thrower in the manual from Mega Man for Game Gear, is an enemy in Mega Man 4, Mega Man IV and the Game Gear Mega Man. It is only found in Bright Man's stage, and often with the 100 Wattons. If a 100 Watton was destroyed, destroying one Dompan will turn the lights back on.

Trivia
