go to the trophy garden and walk around allot
pikahu i quess
i think you fnd pikachu in the power plant.
Yes, i beat misty w/ a lvl 31 charmander, all you need is an electric poke' mon , i have a pikahu (i got him in the viridian forest ). You have to go the house that had been robbed from by team rocket (the one with the police at the house). after you beat the team rocket guy he gives you dig. then give dig to your charmelon. keep using ember on the first poke' mon and keep using dig on the second one.
The only difference really is the name and appearance. Even if they don't evolve they will still be able to learn the same moves and keep moving up levels. They may be able to learn new moves if they do evolve, as well as benefits like stat increases and sometimes new hold items becoming useful or not, in the case of Pichu-Pikachu-Raichu, the Light Ball only works on Pikachu.
you can't catch a pikachu lv.191 there is n such thing only lv.100 they stop..=D
