Hakuryuu - Eevee

Eevee

Eevee (イーブイ, Ībui?, Eievui), known as the Evolution Pokémon, is best known for its unstable genetic code which allows it to change and mutate into different forms depending on its environment. As a result of its evolution, Eevee would become better suited to living in its surrounding environment. All of Eevee's evolutions are of unique typing in comparison to each other. In Pokémon Red and Green, the player was able to evolve his or her Eevee into one its first three evolutions (Vaporeon, Jolteon, or Flareon) by the use of an elemental stone (though only one can be obtained at a time). Starting from Pokémon Gold and Silver, the player could further evolve his or her Eevee into either an Espeon or an Umbreon by making the Eevee to achieve maximum happiness (though the evolution depended on what time of day it was as Eevee evolved into Espeon at daytime while Eevee evolved into Umbreon at night). The final two evolutions of Eevee were obtainable upon the release of Pokémon Diamond and Pearl. Leafeon, Eevee's grass type evolution is obtainable upon leveling up near a moss rock, meanwhile Eevee's ice type evolution, Glaceon, is achieved by leveling up near an ice rock. These rocks are found in the Sinnoh and Unova regions.
