I say just keep battling weak pokemon or normal ones
no. the games have never made a place to get lv. 100. they can only be borrowed in the pokemon battle frontier. or level your pokemon up. hope this helped!
You can't put level 100 Pokemon into your room. You can only put up to level 50 Pokemon inside, but what's strange is that I once saw level 60 Pokemon in someone's room. I can't recall which though.
You level up by battling wild Pokemon, Trainers, and Gym Leaders.
rare candy
you can get in a double battle and win to level up magikarp
Defeat wild Pokemon or trainers Pokemon then go to the Pokemon center and heal your Pokemon notice your Pokemon's level went up.
You cant its impossible in every Pokemon game. you might be able to do it on action replay though but i don't think so. A Pokemon can only go up to level 100
Level it up to level 16 into Combusken then level 36 to make it into Blaziken.
Yes you can! Level it up to 30 to 50th level. I've caught it!
Pokemon deluge is good if you like leveling up fast. I u play a decent 1 hour you can get 6 Pokemon to level 100. Pokemon indigo is long but decent. You will get bored of it after a while
Train your pokemon.
Easy, just make sure the Burmy is Female and train it. Same with Mothim exept the Gender is different.
