Thank you, the reason I want Fire Fang back is because it is Physical move and my Charizard is Adamant Nature.Well, Flamethrower is actually a much better move than Fire Fang, but go to the house next to the water in Pastoria and give the guy a Heart scale (can be found underground) and he'll reteach any past move.
Is a Pokémon with Poké R Us worth more than one which is not infected? I know what PKRS does and all but does it decrease the value of infected Pokémon?
