In Vs. Dragonite, Dragonite is the guardian of the Hall of Origins, preventing anyone from getting in. It is naturally angry, and violently attacks Shadow and Domino upon entering.

Shadow then catches it.
In New Moon Shines on the Collector, Dragonite is chosen to fight to steal Marshadow. Dragonite primarily battles Ian's Charizard and Crystal's Pelipper, it easily overpowering the two of them combined but unable to defeat them. It holds them off until Zapdos appears and distracts them, allowing it to defeat them.
Later, Dragonite was chosen to chase Pelipper in order to get Marshadow back. It is confronted by Charizard again, the two battling again. The two are even, as Charizard prepares to attack. Crystal's Mismagius appears and protects Charizard from Dragonite's Hyper Beam. Dragonite tries to attack Mismagius but it flees, causing Dragonite to be defeated by Charizard's Blast Burn.

It later battled alongside Gyarados against Latios and Latias. The two do well and injure the Legendary Pokémon, Dragonite using Draco Meteor to counter the two.

It is defeated by Lopunny's Ice Beam that is arched around at it.
