As Ash's training draws to a close, a young Trainer named Shauna, who claims to be the top apprentice of Gym Leader Brawly, challenges him to a Pokémon battle. Before they are able to complete their battle, however, Brawly himself shows up to warn of an approaching hurricane. It seems his warning is a touch too late, though, as heavy winds and rain begin buffeting the shore where Ash and friends have pitched camp. While the storm draws nearer, they carefully make their way along a treacherous mountain path, seeking shelter in a cave, where Brawly explains that Shauna isn't really his apprentice--he hasn't let her join him because she is too headstrong and needs to learn control and patience. After the storm passes, she finally proves herself in a battle with Ash, and Brawly accepts Ash's challenge for a rematch!
