CWU-01P is an aquatic robot from the first Mega Man game that was originally created for water purification, but is used by Dr. Wily to protect his fortress.Its weakness is the Super Arm, but the Fire Storm works just as well In the first game, there are seven CWU-01Ps that roll through the room inside of bubbles and shoot three bubbles at the enemy. The seven are the same, except that they have different speeds and different colors in the circle on them. They appear one by time, and when one CWU-01P is defeated, the next will be faster. Each CWU-01P defeated removes 4 HP from the total HP.
