FAQ
What order are the Gyms in Pokémon Yellow?
Brock (Rock), Misty (Water), Lt. Surge (Electric), Erika (Grass), Koga (Poison), Sabrina (Psychic), Blaine (Fire), Giovanni (Ground).
What level should I be for each Gym?
Brock: Lv. 12, Misty: Lv. 21, Lt. Surge: Lv. 28, Erika: Lv. 32, Koga: Lv. 50, Sabrina: Lv. 50, Blaine: Lv. 54, Giovanni: Lv. 55 (their strongest Pokémon).
Is Brock harder in Yellow?
Pikachu’s Electric moves do nothing to Geodude and Onix, so you need another Pokémon: Mankey’s Low Kick, Nidoran♂’s Double Kick or a Butterfree with Confusion all work.
