Water Wave

Water Wave is 's down special move in Super Smash Flash 2. Mega Man fires a very weak projectile in the air that falls steeply downwards, and if it comes in contact with the ground, it transforms into six small, medium-ranged waves, that have wind boxes, to attack the opponent. A few seconds after using the move, a visual effect and sound will play to indicate when Mega Man can use the move again. The move is an excellent edge-guarding or edge covering move as the waves can either prevent opponents from getting up from the ledge or cover Mega Man's approach to the edge.

Origin
The Water Wave is a weapon acquired by defeating Wave Man in Mega Man 5. In this game, the player can send out three water spouts as a small wave across the floor that can absorb some enemy projectiles. It will stop when it hits an enemy that is strong enough to sustain the hit, or when it hits a wall. When it reaches a ledge, it will fall off and continue to move across the floor beneath it, provided there is one. The waves can only be fired when the player is in contact with the ground and cannot be used in the air, on a levitating platform, or at the very end of a ledge. In SSF2 it works very similarly to its Mega Man 5 counterpart, except the player can use the move in the air and the waves will stop after a certain period of time. Additionally, instead of stopping at walls and traveling down ledges, the waves strangely tend to travel up walls and stop at ledges.
