Water Balloon (ウォーターバルーン Wōtā Barūn) is Aqua Man's Special Weapon from Mega Man 8. When equipped, Mega Man shoots a sphere of water at a low arc. Unlike most Special Weapons in this game, there is no limit as to how many Water Balloons are allowed on the screen: the player can shoot a stream of as many Water Balloons as they wish as long as it has enough Weapon Energy to do so.

Water Balloon is the most effective weapon for fighting Sword Man, but is also very effective against the first form of Dr. Wily's Wily Machine.
