Water Attack is a type of sticker power-up that adds damage to attacks imbued with water, such as Squirtle's Down Smash. Squirtle and Greninja are the only characters to possess water damage on its attacks, while Mario's F.L.U.D.D. does not do any damage, but rather pushes opponents back a distance.
