Sky High Gym Battle!

After the excitement of the Feather Carnival, Ash is more than ready for his sixth Gym Battle. Ash decides to begin with Grovyle, while Winona begins with Altaria, a Flying/Dragon type. Despite the type disadvantage, Grovyle's speed is able to get the better of Altaria's power and is able to defeat it. Winona then decides to send out Pelipper, and Ash recalls Grovyle for some rest and sends out Pikachu, which has a double type advantage. However when Pikachu tries a Thunderbolt, Pelipper is able to channel it into the ground using Steel Wing. After a furious shooting battle, Pikachu and Pelipper knock each other out. Down to her last Pokemon, Winona sends out her Swellow, which is Shiny and therefore has higher stats. With a weakened Grovyle and his own Swellow, can Ash defeat Winona and win a Feather Badge?
