I believe you mean with an evolution stone or from trading, correct? If so, I would wait until you have the Pokemon to the point where it has learned any attacks that its evolved form cannot learn that you may want. An example is Pikachu. Almost all of Pikachu's attacks are not able to be learned by Raichu. Take that into consideration.
Well, it depends on what Pokemon it is.
It doesn't evolve by itself you have to give it an evolving stone
The everstone is used to PREVENT evolution, so none evolve with it. When a Pokemon holds one, and reaches the level it usually evolves, it won't even try. You would need to remove the everstone and level the Pokemon up another level to evolve it.
Yes, a Pokemon that has been stopped from evolving will continue to attempt to evolve until it reaches level 100.
it is ok if you are looking to battle and catch wild pokemon as it is not powerful, but if you are talking gym battles and such i would suggest (if you are looking for a bird type pokemon) evolving a pidgey, which is not too hard as it evolves at level 18 into pidgeotto, and then again at level 36 into pidgeot. much better than a farfetch'd. hope I helped XD
train them a level higher
Well, it depends on what Pokemon it is.
it depends on the Pokemon that are evolving
If you accidentally pressed "B" while your Pokemon was evolving, all you have to do is level it up again.
It depends on the level if the level is higher that means it's stronger.
You can get Charizard in Pokemon Blue by trading with a friend who has Pokemon Red,Blue,Yellow or starting out with a Squirtle from Proffesor Oak and evolving it at Level 16 to get a Charmeleon, then evolving the Charmeleon at Level 36 to get finally get Charizard.
By evolving Pupitar at level 55
It depends on which Pokemon it is because they all have different evolving levels.
Train nincada to level 45 without evolving it. Train nincada to level 45 without evolving it. Also, Train Trapinch till level 41 without Evolving. (Key:- When the Pokemon is evolving, keep pressing B)
If you stop a Pokemon from evolving, it`ll try to evolve every level after that unless it`s holding an everstone.
You just need to level it up a bit and it will evolve.
Before, because it is easier to level Pokemon with a strong type like fire etc. Normal type isn't that great. Hope I helped!
