After attacking Rowlet during Ash’s grand trial, Rockruff is too upset to sleep. It sneaks out of the house and encounters Tapu Lele, who wants to battle! The Island Guardian thinks they’re just having fun, but Rockruff is badly hurt.
Olivia’s Midday Form Lycanroc and Gladion’s Midnight Form Lycanroc discover the injured Rockruff and take it to Tapu Lele for healing. After Ash comes looking for his friend, Tapu Lele uses Draining Kiss to take energy from both Lycanroc and give it to Rockruff. Rockruff is feeling better—and then it evolves into a Lycanroc no one has ever seen before, a Dusk Form Lycanroc with bright green eyes!
