An 'Eeveelution' (Japanese: ブイズ Buizu) is a popular term among fans that is used for the current group of eight Pokémon that evolve from Eevee. Eeveelution is a portmanteau from the words "Eevee" and "evolution". The term Eeveelution is because Eevee can evolve in different kinds of other Eeveelutions but with different kinds of types. The Eeveelutions are very liked among collectors when it goes about a full set of all eight evolutions including Eevee.
Many Eeveelutions have made their first appearances in almost every Pokémon handheld game since Generation I. The first three to be introduced in the first generation are Vaporeon, Jolteon and Flareon, which evolve from Eevee through the use of a Water Stone, Thunderstone, and Fire Stone, respectively. Two more Eeveelutions were later introduced: Espeon and Umbreon. These two can only evolve from an Eevee with a high level of happiness, and at different times of the day (Espeon during the day/morning, Umbreon during the night/dusk), starting in Generation II, and onward. In Generation III, no new Eeveelutions were introduced, but in Generation IV, two new Eeveelutions were created, which are: Leafeon, who evolves from Eevee when leveled up near the green moss stone in Eterna Forest, and Glaceon, who evolves from Eevee when leveled up near an ice rock on Route 216/217. In February 2013, Nintendo revealed a new Eeveelution for Generation VI, named Sylveon.
