Synopsis

As Ash and his companions journeyed toward Pastoria City, they encountered a trainer named Tyler, eager to capture a Yanma. Unfortunately, Team Rocket intervened, weakening the insect before seizing it for themselves. Jessie, after successfully capturing the Yanma and reporting to Giovanni, received a dismissive rejection. Undeterred, she resolved to train the Pokémon herself, and it swiftly evolved into the formidable Yanmega.
