Battling at Full Volume!

Rock guitarist Jimmy and his Pikachu, Spike, are always looking for other strong Pikachu Trainers to battle, and Team Rocket points them in Ash’s direction! But Ash is in bed with a fever, and when Jimmy shows up, Serena is torn—she knows Ash is always up for a battle, but he needs his rest. So she decides to disguise herself as Ash, and Pikachu plays along!
The battle is going well for Serena when Team Rocket swipes both Pikachu. Fortunately Ash has a quick recovery and helps her defeat the villains. Jimmy is impressed with Serena’s battling skills, but he still wants to challenge the real Ash—right after lunch!
