Staryu

Staryu, known in Japan as Hitodeman, is a Water-type Pokémon that was introduced in Generation I that is located in the region of Kanto. It evolves into Starmie when exposed to a Water Stone.

Pokémon description
Staryu is a golden-brown sea star-like Pokémon with five appendages. These appendages surround an exterior organ called the core, which is held in place by a golden ring looped around Staryu's left "leg". If any of Staryu's appendages are lost, it can grow them back with ease provided the core is still intact. The core resembles a red jewel and is similar to a madreporite. Staryu is a natural prey of some species of Pokémon, including Lumineon. However, due to its regenerative abilities, being preyed upon does not negatively affect it.

In Super Smash Flash 2
Staryu is one of the Pokémon that can be released from a Poké Ball in Super Smash Flash 2. Once released, Staryu will target one of the opponents, spin towards them and shoot Swift. It is rapid-fire, but the player can still move around while getting hit, so it can easily be escaped from with the correct directional influence.
