There's big trouble in the big city when Ash and our friends pay a visit—a mysterious talking Pokémon known as Red Lighting has been battling all the Trainers in town, and it acts like a real bully when it wins! May's plans for a nice day out are ruined when Red Lightning humiliates her and her Squirtle, so now our heroes are out to uncover who or what is behind its activities. To catch up with it, our heroes commandeer Team Rocket's balloon and follow Red Lightning back to a huge house. There they meet Red Lightning's owner, a little girl named Luna. Luna isn't about to apologize, so Pikachu battles Red Lightning and the truth is revealed: Red Lightning is a Scizor in disguise! Luna was behind the whole thing, even equipping her Scizor with hidden speakers so she could be its voice. With or without a costume, however, her Scizor is incredibly fast. To keep up with its speed, Ash decides to call on Sceptile. When Scizor ends up on the losing end, Sceptile even saves it from a nasty fall, but Luna is less than grateful. Luna's butler explains that her parents are often away due to work, and that's why she has an attitude that started all the Red Lightning trouble. To help her feel less lonely, May challenges Luna to a real Pokémon battle. Squirtle comes out the victor in its rematch with Scizor, but Luna doesn't mind. She doesn't need to pick on Trainers now that she's experienced a fair Pokémon battle, and she'll be cheering for May as our favorite Pokémon Coordinator heads to the next Contest!
