The Battle Park is an anime location in Pokémon: Master Quest.
The park has strong, rental Pokémon which visiting Trainers can battle against. The park's Pokémon are trained to be obedient while inside the park and to return immediately if they get lost or stolen. Ash, Misty, and Brock go there after an unnamed Trainer tell them about this. Team Rocket, while dressed as park employees, temporally worked there.
