Enter Iris and Axew!
Pikachu mysteriously gains its power back after Zekrom creates another harrowing lighting storm. Ash decides to remain in Unova with Pikachu in order to conquer the league. Professor Juniper informs Ash that the closest Gym is in Striaton City, so that is where he heads off to after saying goodbye to his mother and the Professor.
While figuring out which Pokémon type will be his first capture in the new region, Ash and Pikachu hear a rustling in the bushes. Mistaking her for a wild Axew, Ash throws a Pokéball at Iris who is infuriated by his mistake; Iris quickly forgets about this when she sees Ash's very-rare-in-Unova Pikachu. The Oshawott from Professor Juniper's lab follows Ash.
Team Rocket make their first contact with Giovanni at headquarters and later attempt to catch Pikachu and Iris' Axew. Jessie uses her newly-caught Woobat to battle and win against Ash's Pidove. Oshawott runs into battle to save the day and releases Pikachu and Axew. Team Rocket make a quick exit.
