Gary Oak's Cheerleaders follow Gary around the Kanto region giving him vocal support during his Pokémon battles.
The Cheerleaders enter themselves in the Swimsuit Beauty Pagent in Porta Vista and managed to excited the crowd and Brock who was commentating on the event. Whilst the cheerleaders were ecstatic when Gary won they would also be unconsolable when he was defeated, especially when he lost to Giovanni in a Gym Battle and to Melissa in the Kanto Pokémon League.
After the Kanto Pokémon League Gary's Cheerleader left the Indigo Plateau with Gary.
