Carlita used her Hydreigon in a battle against Cilan and his Pansage. Iris came to watch their battle after she lost hers and became excited over Carlita's Hydreigon because it was dragon-type. Carlita took her chance and ordered her Hydreigon to use Dragon Breath, successfully hitting Cilan's Pansage and knocking it out, eliminating Cilan from the tournament.
Later, Carlita and her Hydreigon faced Ash Ketchum and his Scraggy in a battle. Scraggy used several Headbutt on Hydreigon, but Hydreigon didn't even react on it and knocked Scraggy away into the tree. Scraggy fell down the tree and once it fell down, it received some power from Victini, which was seen by Carlita. After receiving some power from Victini, Ash ordered Scraggy to use Headbutt once more, and this time it successfully knocked Hydreigon far away, eventually knocking it out and eliminating Carlita from the tournament.
Hydreigon was later used to bring both Carlita and Iris to safety when the castle started to collapse.
