You can evolve a level one Pokemon by using a stone such as fire stone, earth stone,etc. It depends on what type your Pokemon is like electricity, water, blah blah blah.You can get them at the pokelathon in soul silver
Emolga does not evolve. I played Pokemon White also and it does not evolve. Some Pokemon do but this one does not evolve.
Mew is one of the many Pokemon that does not evolve
Lombre is one of the pokemon that do not evolve by level he evolves by using a water stone.
You have to Level it up in Battles. Once you get to a certain level... It will evolve right after. Another way pokemon evolve is frienship, once there happiness level is high enough, and you level them up one more level they will evolve. The last way for Pokemon to evolve is with a stone. Few pokemon evolve from evolutionary stones, but when they do they evolve as soon as you use it on them.
It depends on the Pokemon. Some of them you have to evolve by using stones. Others don't evolve at all. There is not one level that all Pokemon evolve at(unless you use an everstone on them until level 99, then level it up once more to level 100, but that would be a waste of time).
If any pokemon is caught at the level it would normally evolve you will need to train it one level more to evolve it. A Maril evolves at level 18 so you just need to train it one more level to evolve it.
Be specific. What pokemon? ---------------------------------------- Most of them evolve at level 16 than level 36 :)
if you get a Pokemon that is higher than it's evolved level, say, a level 65 dragonair that evolves at level 55 (true) and you catch it in the wild. just level it up one and it will evolve.
its beauty must be high then raise it one level and it will evolve into milotic
Pinsir is one of the many pokemon that don't evolve.
I know Shroomish evolve at level 23 Brelum are great Pokemon (Try to evolve one see what happens!)
golbat can evolve at any level if its friendship is up to max power...or...it can evolve if you give it a berry that gets the Pokemon friendlier then get it one level higher and ... evolution
