The Rival will eventually evolve his Eevee (and thus affect which are the other members of his party) depending on the player's actions early in the game.
hope this helped!
To get an Umbreon, you have to trade your Eevee to Pokemon Ruby, Sapphire, or Emerald, because there needs to be time if you're going to evolve Eevee into Umbreon. Keep Eevee with you until its happiness is at its highest, then evolve it with a moonstone WHEN IT IS NIGHT ACCORDING TO THE GAME CLOCK.
Only train Eevee during the night. It will evolve by friendship.I have one so i know exactly how you're going through it.HOPE THIS HELPED! :D
In Pokémon Diamond, in order to get the 7 evolutions of Eevee, you'll need 7 Eevee first and then you can use a Water Stone, a Thunder Stone and a Fire Stone on 3 of them in order for 1 of each to evolve into Vaporeon, Jolteon and Flareon. You get Umbreon by evolving Eevee between 8 PM and 4 AM when it has maximum happiness and you get Espeon by evolving Eevee between 4 AM and 8 PM when it has maximum happiness. You can evolve Eevee into Leafeon by going to the Moss Rock in Eterna Forest and leveling it up there. You can evolve Eevee into Glaceon by going to the Ice Rock that's near Slowpoint City and level your Eevee up there.
you get a leafeon by going to eterna forest with an eevee. Go to the mossy stone(hidden so use some repels)then level up your eevee and it will evolve into a leafeon.
Dude, buy a DS and then buy Pokemon, Pokemon crater is a waste of time!!!!!!!! I'm going to assume crater is a hack for the gameboy advance. Eevee can evolve with a fire stone, water stone, thunderstone, max happiness (different in AM and PM).
You can either use a water stone, a fire stone or a thunderstone. You can find these stones in Solaceon Ruins by going to the random stones and clicking on them.
To evolve Eevee in Pokemon Battle Arena (Pokemon Crater), You buy from the pokemart a: Water Stone: Vaporeon Fire Stone: Flareon Thunder Stone: Jolteon Moon Stone: Umbreon Soul Dew: Espeon Leaf Stone: Leafeon Nevermeltice: Glaceon Then you go to Trainer HQ, My Pokemon, find your Eevee and click Evolve Me, and evolve it into any of the Pokemon above. In games for DS and Gameboy, you evolve Eevee into Vaporeon, Jolteon or Flareon using stones, into Espeon by making it love & trust you completely in daytime, into Umbreon by making it love & trust you at night time, into Leafeon (Sinnoh only) by going into Eterna forest and touching the mossy rock with Eevee in you party, into Glaceon (Sinnoh only) by going to route 217 and touching the rock covered in ice with Eevee in your party. NOTE: You might have to level your Eevee up next to the rock when trying to get Leafeon & Glaceon. Also to make your Pokemon love you and trust you completely, give them poffins/pokeblocks that they like, battle with them, give them massages, ect.
First you'll need an Eevee (duh). Go to the mossy rock in Eterna Forest and level Eevee up in the grass there. It will then evolve into Leafeon. To get an Eevee, you'll need the National dex. Then go into Bebe's house (the PC girl) and have an empty slot in your party. She will then give you an Eevee. You do not need the National PokeDex to get the Eevee from Bebe. Another way of getting an Eevee is going to Trophy Garden place, going into Mr.Backlot's office and talking to him, save before you talk to him and just keep talking to him until he says that an Eevee came up to him. O and answer Yes to any question he asks you. Then just catch your Eevee's. Also if you get your friend to give you a Ditto, then just go to Solaceon Town and put the Eevee in with the Ditto and then breed as many as you want. Have fun ~ Dinosman.
To get an Umbreon, upgrade an Eevee at night (8:00p.m. - 4:00a.m.) while holding a Soothe Bell. In other words, have an Eevee happy with you and upgrade it at nighttime.TIP: Ways to get it happy with you are to feed it a LOT of vitamins, and holding a Soothe Bell. Just upgrade it 1 level (make sure it likes you) and it WILL evolve to an Umbreon.
Go in the back of the Celadon Mansion and keep going up and you will get a free Eevee
try going to the trophy garden
If you mean how to make it evolve: In SoulSilver and HeartGold, you can get an Espeon by training your Eevee in the day time, and at a certain lvl. it will evolve into Espeon. To get Umbreon, you do the same thing, except you train it at night (it may take a couple tries when it's going to evolve to get it to evolve into Umbreon if you've trained it in the day time, too). To get Jolteon, use a thunder stone. Flareon, fire stone. Vaporeon, water stone. To get Leafeon and Glaceon, trade to Diamond, Pearl, or Platinum, and for Leafeon, go to the forest after the 'Flower Town' and make it go up a lvl. and it should evolve into Leafeon. For Glaceon, go to the snowy rout, and make it go up a lvl. and you get a Glaceon. Then trade back to get it in HeartGold/SoulSilver.
