Name: Xahine (pronounced zuh-HEEN)
Eeveelution: Eevee (can freely evolve into all formes)
Bio: Xahine used to belong to a kind trainer named Mario, until criminal scientists stole it from him to experiment on it. It was forcefully evolved and devolved into Jolteon, Flareon, Vaporeon, Espeon, Umbreon, Glaceon, and Leafeon, then was cloned to create an army of perfect Eevees. Xahine was shortly released after, and has since turned very bipolar, falling into traumatic breakdowns when even slightly reminded of his brutal past. He is a very skilled fighter though, and can freely shift between formes, covering just about any weakness he has. However, he doesn't often use this ability, as he is always reminded that it was the cruel maniacs that used it like a lab rat that gave it the ability in the first place.
