You have to trade eevee to a game with a time system (ruby, sappire, emrald, gold silver crystal, diamond, pearl or platinum) and raise it up at night.
so far, you cannot evolve eevee either to umbreon or espeon on FireRed because on FireRed and LeafGreen, there is no clock system. You must trade eevee to Emerald for evolving to Espeon or Umbreon
No; Umbreon didn't exist that early in the series.
You cannot get umbreon in firered you need to have ruby, sapphire or emerald give you one or take the one from Pokemon colosseum.
you cant umbreon doesn't exist in fire red
Yes it is possible to get Espeon and Umbreon in Pokémon FireRed but you cannot physically evolve Eevee into either Espeon or Umbreon in Pokémon FireRed due to there being no time cycle in the game so you will need to evolve Eevee into Umbreon or Espeon in Pokémon Ruby, Sapphire or Emerald and then trade it over to FireRed.
Umbreon can only be gained from trading from Ruby, Emerald, Sapphire, Pokemon XD or Pokemon Collosseum.
you can't it's so impossible
Yes you *can* get umbreon in Fire Red, I myself am trying to figure this out, if you look around on sites (just google them) you should be able to find some hints...but none have been of definite help so far... =\
You can only trade it from the Johto region or the Hoen Region.
Clefairy, Jigglypuff. Umbreon. etc.
you can't. to get an espeon or umbreon, you need to evolve an eevee at certain time of day. leafgreen/firered don't have clocks. you have to trade the eevee to ruby/sapphire, max out friendship and level up in the pm for espeon, am for umbreon.
You don't use a stone at all. Eevee evolves into Umbreon via happiness, followed by a level up AT NIGHT.
