well if you ask me it is umbreon,glaceon,leafeon
umbreon-make your eevee very happy with u then level it up/train it at night or use a rare candy
glaceon-go to snowpoint city then go to the horrid route go to the right near the ice stone close to the house level ur eevee up there
leafeon-do the same as u did with glaceon but apart from snowrout u go to eterna forist and find a moss stone
Personally I think Eevee is the best Pokemon ever because, it can evolve into seven different types of Eevee.
The strongest one Espeon or status problem ones Flareon Glaceon and Jolteon.
It depends on your preferences, but I'd say Espeon and Glaceon.
Eevee it'll evolve in a Jolteon. You can also use it on a Pikachu it'll evolve in a Raichu.
It's cool pokemon that can evolve into a bunch of other cool pokemon, but it's far from being the best. It's evolutions aren't the best either.
Both at level 30
it depends on the type of personAnother OpinionEspeon or status problem ones like Jolteon Flareon and Glaceon. Another OpinionEevee's best form are Leafeon, Glaceon, Espeon, and Umbreon.
in my experience its best to do such things after the Pokemon league. that's how i made my golbat into a crobat at lvel 22 and eevee into an espeon at level 18
Umbreon. It's the Dark type. Level up an Eevee at night when it likes you.
well it ... doesin't matter what is the best eevee evolution is but if it matters to you i'd say espeon is the greatest eevee evoultion no jolteon it 1 of the 1st eevee evolutions and has incredible speed, like all electric types i'd go with jolteon if i were u oh and vapoureon if u don't want jolteon cuz water types are quite fast too
You cant evolve it into glaceon unless you bring an ice stone over from a game that has more stones than silver, (silver doesn't have to many.) after transferring it, eevee will evolve. The best you can do without an ice stone is espeon(if it evolves in day) or umbreon (if it evolves in night).
to evolve eevee into sylveon, you need to level it up with maximum two affection hearts on pokemon - amie plus it has to learn a fairy type move. your best best is level it up to level 29, as it would learn charm, which asof gen VI is a fairy type move
