Goh has caught lots of Pokémon so far, but which to catch next? Admiring the close bond between Ash and Pikachu, he decides to catch a Pikachu of his own. Coincidentally, Professor Cerise wants our heroes to research a Pikachu outbreak, so they’re off! When they arrive, Goh catches a female Pikachu, whose friends are digging Thunder Stones out of the nearby rocks so they can evolve into Raichu. But Team Rocket arrives, and they manage to round up not just the wild Pikachu, but Ash’s Pikachu, too! But Goh’s Pikachu knows just what to do to send Team Rocket blasting off. (Source: Wikipedia)
