Hydro Pump

Hydro Pump is a powerful Water-type move recurring in the Pokémon series that makes appearances in the Super Smash Bros. series.

In Super Smash Bros. and Super Smash Bros. Melee, Hyrdo Pump is the move used by Blastoise when it is summoned from a Poké Ball.

In Super Smash Bros. Brawl, Squirtle uses Hydro Pump in the Pokémon Trainer's Final Smash, Triple Finish.

In Super Smash Bros. for Nintendo 3DS / Wii U, Hydro Pump is Greninja's up special move. When used, Greninja launches itself up into the air with two blasts of water from its palms. Players can fling themselves in any direction with each blast by angling the Control Stick or Circle Pad in the appropriate direction. The move can also damage opponents and push them away.

The first custom variation for this move is High-Capacity Pump, which enables Greninja to fire water pumps that are easier to control, and offer greater distance overall than Hydro Pump, but the move travels slower than normal, and is not able to deal any damage.

The second custom variant is Single-Shot Pump, where Greninja launches itself straight up with a single water pump, which covers more vertical distance than Hydro Pump. The move's angle can't be changed, however.
