No because leafgreen has no in game clock feature so to get umbreon you need to train an evee in a game that has an in game clock such as ruby or diamond then once evee has max friendship it will evolve to umbreon during the night time.
you need to get evee and give it love in the morning to get Espeon and at night to get Umbreon
Trade it to ruby,sapphire or emerald have them evolve your evee at night then give it back to leafgreen.
get 2 evee's train er in nacht en een in de dag
You have to wait a while after you get to pick who evee will evolve into (umbreon) You have to wait a while after you get to pick who evee will evolve into (umbreon)
No but you start with two evee forms: Umbreon and Espeon.
Golbat---> Crobat Evee---> Umbreon or Espeon
it depnds were u evolve it
Evee can be obtained only from firered and leafgreen and Pokemon xd gale of darkness.
No because the game lacks the built in game clock feature which lets the game change from day and nighttime which is essential for evee to evolve to Espeon or Umbreon. If you want these pokemon you will need to use Ruby, Sapphire or Emerald to evolve the Evee because these games have the in game clock feature or you can even trade the Espeon and Umbreon from pokemon colosseum.
You can't leafeon doesn't exist in leafgreen.
You can get lucky train a evee so that its happiness is at the max with you it will hopefully evolve to espeon this is random though you may get umbreon so your going to have to get one from a trade.
