There is no stone needed to evolve (although i think it should evolve with sun stone) .But your friendship with the eevee has to be very good then and only then will it evolve into an espeon
A Flareon
No, Eevee does not have to evolve to breed.
Eevee can not evolve into porygon.
It depends when eevee will evolve. Eevee can evolve at any level if you use one of the stones (fire, water and thunder) or, you have to use eevee in battles so it becomes freindlier (use soothe bell as it will help it work faster). My guess that eevee will evolve around 35-50.
eevee can only evolve once but if you get another eevee (of different gender )and breed with it you can get another eevee and evolve it into something else.
well, eevee is not a good pokèmon, so yeah, or at least I would have done it
you cant evolve eevee into glaceon.
if i get eevee in level 20 what level eevee need to evolve into espeon
You want both? Well, to have both I would breed the Eevee. So then you could evolve one Eevee into a Glaceon, and the other is still the same Eevee. You evolve Eevee into Glaceon when your near Snow Point City, you'll see a ice rock in the middle of some grass. Level Eevee up somewhere near that ice rock, and it should evolve.
If you have made your eevee evolve and still need to get data on a different evolution the easiest way is to breed the eevee evolution (Vaporeon for example) the resulting egg should hatch an eevee that you can evolve into something different.
No, Eevee does not evolve with a Shiny Stone. Only Togetic, Roselia, and Chillarmy evolve with it.
