100 Watton is an enemy robot from Mega Man 4. Appearing in Bright Man's stage, this flying lightbulb will fly from one side of the screen to the other, dropping a bomb on the way. The bomb that it drops will scatter five projectiles in a downward spread. One buster shot is enough to kill it, but doing so will turn out the lights in the stage, leaving Mega Man in complete darkness and unable to see traps or pitfalls. The lights can be restored by destroying a Dompan.
