Eeveelution

An Eeveelution is a popular fanon term for the current seven Pokémon that evolve from Eevee. It is derived from a combination of the words "Eevee" and "evolution".

It is also the name of a TCG Themedeck, see: Eeveelution (TCG). However, it should be noted that the term appeared before the release of the Themedeck.

Trivia

All of the Eeveelutions have had the Elemental types of the Special category. (Water, Electric, Fire, Psychic, Dark, Grass, and Ice). To pre-Generation IV standards of course. The only Special Elemental type not yet covered has been the Dragon-type. This might indicate that the next Eeveelution, if any, could be a Dragon-type. There has yet to be an Eeveelution with a Physical elemental type.
