Eevee is a rather unique Pokémon because it is capable of evolving into one of seven Pokémon. Each of Eevee's evolutions harnesses its own type and learns attacks according to that type. According to in-game Pokédex entrys, Eevee can evolve into all its evolutions because its complex DNA will adapt to harsh environment conditions depending on its location. All evolutions of Eevee end with the suffix "eon", meaning "long period of time".

Below is a table with all of Eevee's evolutions along with their methods of evolution. These methods reflect the type of the evolution.
