An Eeveelution is a term used for the current group of eight Pokémon that evolve from Eevee. It is a portmanteau of the words "Eevee" and "evolution". Its definition may be extended to include Eevee itself. It originally was an unofficial term used by fans, but the term eventually passed into the realm of official usage first as a pun in the official guide of Pokémon Stadium 2, and then later in the TCG Theme Deck Eeveelution, as well as in the game Pokémon Ranger: Shadows of Almia.
