Eeveelutions are a fan term for the evolutions of Eevee , the Pokémon who can currently evolve into 8 different evolutions!
Eevee is a normal type Pokémon introduced in the first generation. In the first generation it could evolve into 3 different evolutions , Flareon , Jolteon and Vaporeon via special stones. It proved to be very popular amongst fans and was gifted with two more evolutions , Espeon and Umbreon. The third generation was a reboot generation and , to the dismay of many fans , wasnt given any new evolutions. In the fourth generation Eevee was given two more evolutions , Leafeon and Glaceon , who evolved based on location, and were kept secret until the release of Diamond and Pearl. Fans were met once more with dismay in the fifth generation , once again a reboot generation , were Eevee wasnt given any new evolutions. However , in the sixth generation a new Eeveelution , Sylveon ,was unveiled in a Japanese gaming magazine , CoroCoro. It was the source of speculation for many months amongst fans as its type wasnt revealed in the magazine. After many heated arguments of Flying , Normal , Bug and Dragon it was finally revealed at E3 to be an all-new type ; the Fairy type.
There also is speculation about another Eeveelution for Generation 6. Possibly a Dragon type.
Sylveon is a Fairy-type Pokémon.
It evolves from Eevee. It is one of Eevee’s final forms, the others being Vaporeon, Jolteon, Flareon, Espeon, Umbreon, Leafeon, and Glaceon.
