Sylveon first appeared with her trainer when she challenged Ash to a battle, but if he lost, he had to come with her. Ash had Froakie battle Sylveon, but Sylveon won using Draining Kiss & Attract and Ash and his friends came with Penelope. Later, Team Rocket came and captured Ash's Pikachu and Penelope's Sylveon planning on taking them to the boss for some money. But they were rescued by Randall, Ash, and Froakie and they sent Team Rocket blasting off. Sylveon reunited with her trainer and at the end, she was seen saying goodbye to Ash and his friends.
