Train an Eevee during the day time and eventually it will evolve. Trade your Eevee to a Ruby or Sapphire version (because they have the time) and look after it well. Give it items when it is unwell, let it hold an item, train it and keep it at the top of your party. Soon it will come to like you and on the next level, it will evolve into an Espeon (only during the AM hours). Trade the Espeon back to Leaf Green and now you have an Espeon.

Espeon is the psychic evolved form of Eevee. It is a psychic pokemon.
You can't get espeon in leafgreen so trade one from Pokemon colosseum or ruby, sapphire or emerald or Pokemon xd gale of darkness.
- Jolteon- Flareon- Vaporeon- Ubreon- Espeon
Its not possible to get espeon in leafgreen or firered because there is no in game clock so trade evee to a game with a in game clock like ruby and sapphire then train it to become espeon. Optional other ways: If you have Pokemon colosseum or Pokemon xd gale of darkness you can trade an espeon from either game (in colosseum you begin with espeon and umbreon trade espeon to leafgreen and in xd gale of darkness in gateon port a sailor in the parts shop will allow you to get items to evolve your evee choose the dawn shard then train evee a few levels to have it become espeon then trade it to leafgreen remember both colosseum and xd gale of darkness and leafgreen must have be beaten and for leafgreen you need the national dex and the ruby and sapphire to receive the espeon from either game).
espeon evolves from Eevee fromHappiness during the day, or when around a Sun Shard
Enter back door of Celedon Mansion. On top floor Eevee is on a table. I don't think there is a way to evolve it into an Espeon.
Espeon is the Psychic type evolution of Eevee. If an Eevee reaches maximum happiness levels, it will evolve into an Espeon if leveled up during the day time.
get 2 evee's train er in nacht en een in de dag
Espeon is a Psychic type pokemon.
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 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.
