An Eeveelution (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.

Eevee is the base Pokémon of the Eeveelution chain, and is considered to be one of the most popular and fan-favorited of all the Pokémon. Eevee was introduced in Generation I, and can be obtained in Pokémon Green, Red, Blue, FireRed, and LeafGreen at the top floor of the Celadon Condominiums in Celadon City, but the player can only obtain one per game. Eevee can also be obtained in Pokémon Gold, Silver, Crystal, HeartGold, and SoulSilver from the NPC named Bill after speaking to him in his house in Goldenrod City, if you have already meet him in the Pokémon Center in Ecruteak City. There is a second way to obtain Eevee in Pokémon Gold and Silver, which requires the player to obtain a total of 6666 coins at the Game Corner. Eevee is also obtainable as a starter Pokémon in Pokémon XD: Gale of Darkness. In Pokémon Diamond, Pearl, and Platinum, the player will obtain an Eevee from the NPC Bebe in Hearthome City, but there is a difference between versions. In Pokémon Diamond and Pearl, the player will obtain an Eevee from Bebe after obtaining the National Pokédex, but in Pokémon Platinum, obtaining Eevee from Bebe does not need a prerequisite. Eevees can also be found in the wild at the Trophy Garden of Backlot Mansion below Hearthome City. Eevee can also be obtained as a gift in Pokémon Black and White 2 from Amanita in Castelia City, but is extremely hard to find in Castelia City.
