Kahili was atop Skarmory, and threw Poké Balls with her golf club to stop Gladion, and help Sun by delivering the Z-Ring. After the battle, Tapu Lele healed everyone with its power, and used Psychic Terrain to initiate a battle. Kahili had Skarmory attack Tapu Lele with the rest of the group's Pokémon, but was easily blown away by Tapu Lele's power.
Kahili and Olivia were on the former's Skarmory at Exeggutor Island, and were pleased to see that Hala took interest in training his grandson, Hau.
Later, Kahili rode Skarmory, as she was following Tapu Bulu to Ula'ula Island on diverting some of the Ultra Beasts away from Poni Island.
None of Skarmory's moves are known.
