I dont understand what you mean by 'What do you do' you battle with it obviously.
metapod to butterfree evee to leafeon cacnea to cacturne
To get leafeon first get evee.Then go to the moss rock in pinwheel forest.Level up evee near the rock and it evolves into leafeon.
To evolve your Evee into Leafeon, get a leaf stone, and use it on Evee, and it will evolve into Leafeon! Have fun with Leafeon! -Garrett
In Pokemon Diamond, Pearl, and Platinum, if you want to evolve your Evee to a Leafeon you go to the Eterna Forest You will have to level up your Evee there and once it levels up by one level, it evolves to a Leafeon. If you want a Glaceon, you level up eevee on route 217. To get a Flareon, you give Evee a Fire stone. For Vaporeon, you give it a Water stone. And for a Jolteon, you need a Thunder stone.
You level up evee in eterna forest
you can evolve evee to leafeon by taking leafeon to a stone in the forest by the second gym leader.
You can't leafeon doesn't exist in leafgreen.
evee evolves into: Flareon with Fire stone Vaporeon with water stone Jolteon with thunderstone Espeon with friendship Leafeon with somthing idk Unbreon and Glaceon
Glaceon: To get Glaceon you got to have an evee first then go to a route where in snows most likely stand next to a tree that has snow on it give the evee a rare candy and it should evolve to a Glaceon. Leafeon: To get Leafeon you got to have an evee first then go to a forest EX: Eterna forest then stand to a normal tree give the the evee a rare candy and it should evolve to a Leafeon. NO CHEATS!!!!!!!!!!!!!!!!!!!!:)
you can't you have to get an evee
Get an Eevee and go to Eterna forest and level it up. You should have a Leafeon.
In the woods before Eterna, there is a Mossy Rock, you must have an Evee with you and a rare candy, stand next to it and level up the Evee and it will evolve to Leafeon.
