100 Watton (１００ワットン 100 Watton?) is the first of two enemies that control the lights in Bright Man's stage (In Mega Man 4, Mega Man IV and Mega Man for the Game Gear). It flies left and right, occasionally stopping to fire a downwards bullet spread. If it is killed, the area will plunge into darkness, and a Dompan must be destroyed to bring the lights back on. This is potentially dangerous because if they are killed, the player will not be able to see pits.
