Eevee has eight different evolutions in the main Pokémon series.
These forms are Vaporeon, Jolteon, Flareon, Espeon, Umbreon, Leafeon, Glaceon, and Sylveon. Each evolution has a distinct type and appearance, making Eevee unusual among Pokémon with multiple possible evolutionary outcomes.
The first three evolutions appeared in the original generation: Vaporeon, Jolteon, and Flareon. Espeon and Umbreon arrived in Generation II, while Leafeon and Glaceon debuted in Generation IV. Sylveon was introduced in Generation VI alongside the Fairy type.
Eevee itself is a Normal-type Pokémon. Its branching evolution methods have included elemental stones, friendship, time of day, locations, and knowledge of a Fairy-type move, depending on the form and game.
