How to beat Misty in Pokemon Fire Red?

Question

I was wondering how to beat Misty with these pokemon:

Charmeleon: Level 26
Pidgey: Level 15
Spearow: Level 12
Zubat: Level 11
Kakuna: Level 6
Caterpie: Level 5

I also have Pikachu, Rattata, and another Pidgey but there like Level 5 and below.

Basically your going to want to train Pikachu. All you have to do is go back to the bug field where you got it from and just fight the wild pokemon till it levels up to around a level 12.

Since you should never stick with one pokemon, give the pidgey aeriel ace. Flying types are really effective on water types.

- What you do is set Pikachu to as the first pokemon. Then go out to face the wild pokemon. When Pikachu comes out the first move you do is switch out and pick a different, more stronger pokemon (say Spearow). Then get Spearow to kill that wild pokemon. Pikachu will get the XP from the battle. Do this till It's a level 6 then Pikachu can fight for itself.
