Battle Festival Challenge in Shalour City vs Korrina

Ash Ketchum battled against Korrina at the Battle Festival Challenge in Shalour City. During the battle, Ash's Gengar was defeated by Korrina's Mienshao and Korrina's Lucario and it was sent out to face off against both of them who had little damage. Ash's Dragonite was able to fight back and defeat Korrina's Mienshao and then faced Mega Lucario. Despite having taken damage from the previous fight, Ash's Dragonite was able to power up its speed and attack using Dragon Dance. It was revealed that it knew the move Hyper Beam and it tried to use it during the battle but it was blocked during its power up stage. Hurricane then did significant damage to Mega Lucario and the two came to blows with Power-Up Punch and Dragon Claw as finishing moves. Both attacks landed but in the end, Dragonite was left standing to give Ash Ketchum the victory and raise his ranking to 921.
