This Pikachu, nicknamed Spike, is an Electric-type Pokémon owned by Jimmy.
Spike accompanied Jimmy to find strong trainers and usually shook his head when Jimmy played the guitar. Hearing there was a trainer with a strong Pikachu, Jimmy came to the camp, where the heroes were. Serena couldn't do much but to dress as Ash and lend Pikachu to battle Jimmy and Spike. Ash's Pikachu and Jimmy started off with Quick Attack, colliding with each other. Spike tried to use Thunder Punch, but missed. Ash's Pikachu fired a Thunderbolt, but Spike used Dig, evading the attack. Ash's Pikachu used Iron Tail on the ground, forcing Spike to come out of the hole and to be hit with the same attack. After being interrupted by Clemont and Bonnie, Serena had Pikachu use Thunderbolt, which collided with Spike's Thunderbolt. Just as Spike and Ash's Pikachu used Quick Attack, Team Rocket captured both Pikachu. Once Ash recovered, he had Greninja use Cut, which freed his own and Jimmy's Pikachu, Spike. To finish up, Spike and Ash's Pikachu fired Thunderbolt, blasting Team Rocket away.
