Brock used his Geodude against Red and Red's Charmander in the gym battle. Charmander used Scratch and Ember on Geodude but weren't effective. Geodude countered back with Tackle, almost taking Charmander out. Following Brock's advice, Red switched Charmander out for his Nidoran♂. Nidoran♂ was able to knock Geodude out with Double Kick.
