Once the heroes visited the Gym, Misty freaked out when she saw Caterpie and Metapod, claiming the Gym was a torture chamber. Bugsy sent Metapod against Ash's Chikorita, after she defeated Bugsy's Spinarak. Chikorita attempted to hit it with Vine Whip and Razor Leaf, but Bugsy's Metapod had hardened, rendering the attack useless. Chikorita was then defeated by its Tackle. Ash sent Pikachu, whom Metapod tried to tackle. The dust covered the battlefield, allowing Metapod to strike and hide. Metapod tried to repeat this attack, but Pikachu used Agility to dodge and defeated it with his Thunderbolt. One of Bugsy's Metapod also attacked Team Rocket, who tried to steal the Bug-type Pokémon.
