Piplup

Piplup is a Water-type Pokémon that first appeared in Pokémon Diamond and Pearl. It evolves to Prinplup at level 16, and evolves to Empoleon at level 36. In Super Smash Bros. Brawl, it can be spawned from a Poké Ball and attacks by using Surf; when summoned, it will create a wave around itself and dash towards an end of the stage, pushing any opponent that gets caught along with it. It will move in the other direction if it hits a wall, and will not stop moving even if it falls off the stage.
