Finally able to begin his gym battle in the Mossdeep Gym, Ash is wary of his first simultaneous battle against two gym leaders, but finds them to be far less a challenge than expected. In the midst of battle, however, Team Rocket attacks with an-all new gas-guzzling Pokémon-capture machine built specifically to strip these twin gym leaders of their Pokémon. Jessie, James, and Meowth are quickly dispatched, but when Ash and the trainers rejoin their battle—as though fighting off these villains was just the warm-up they’d needed—the twin gym leaders exhibit far better teamwork than before, promising to give Ash a run for his money.
