Lake Acuity is said to be the home of Uxie, the Legendary Pokémon, but today it's home to a 6-on-6 battle between Ash and Paul! Paul is already waiting on the shore, where he's been training his Pokémon under the thoughtful eye of his brother Reggie. Once Ash arrives, Reggie explains that this battle is a good way for Ash and Paul to test each other. So, once the referee arrives with Team Rocket (disguised as the referee's assistants), it's time to start the match. Ash plans to start by using Buizel, but changes his mind when he sees Paul send out Torterra. Instead, Ash decides to have Gliscor battle first.

Gliscor tries to obscure its moves by kicking up dust, but the trick has no effect. Then Ash orders Gliscor to stay on the offense-and that overconfidence leads Gliscor straight into Torterra's attack! With Gliscor injured, Ash must switch in Staraptor. Torterra is tired too, but Paul keeps it in the battle just long enough to hit Staraptor with Stone Edge. Next, Paul switches in Weavile, which has the speed to keep up with Staraptor. Even so, Staraptor still beats Weavile, and it's time for another round of changes: Paul chooses Electabuzz, Ash sends in Grotle.

To Ash's surprise, Electabuzz uses Light Screen and promptly switches out for Honchkrow.  Grotle is itching to settle an old score with Honchkrow, but Honchkrow still has a type advantage and the protection of Light Screen. What's more, Ash makes a mistake by ordering Grotle to use a defensive move at the wrong time! Honchkrow knocks Grotle out, and now it's Pikachu's turn to battle. Paul responds by bringing out Magmortar, taking Ash by surprise: is Pikachu ready to face the more powerful, evolved version of Paul's Magmar?
