That being Charmander can actually beat Brock without grinding since his mons have no rock moves, have horribly shit special cancelling out the 4x resist, and they don't like burns. Now if you were playing Yellow then fuck yes you had to catch something else. Pic related, is always what I use to get past Brock.
