After Ash's Tranquill replaced Ash's Pikachu in the final match-up in the gym battle, Ash's Tranquill was overpowered by Skyla's Swanna's Hurricane and was knocked down hard to the ground. Ash's Unfezant then evolved from Ash's Tranquill and proved it was stronger and faster than Skyla's Swanna.

Gym Battle against Skyla's Swanna

Ash Ketchum dex and Cilan both noted that Ash's Unfezant was female so it should be able to match or even surpass Swanna's flying abilities. It also learned the new move Aerial Ace. After a short battle based on speed and air maneuvers, Ash's Unfezant used its new move Aerial Ace and managed to catchup and hit Skyla's Swanna in the air. The direct hit proved to be too much for it it and Skyla's Swanna was knocked out and Ash Ketchum ended up the overall victor of the gym battle. Ash's Unfezant proved that it evolving brought in an unexpected element that Skyla could never have predicted in her air battle simulations.
