The battle will be too difficult to beat Pirate Man without his weakness. Mega Man must avoid the Remote Control Mines and then shoot Pirate Man. Later, Pirate Man will be inside a bubble and can be popped by the Mega Buster, when he's not moving. As he moves, the Wave Burner can pop the bubble. Then, Pirate Man will put the water back up to rise the room with more water. Pirate Man then repeats again.
