Dragonair then sensed Team Rocket capturing one of its Dragonite friends, and the group intervened. Team Rocket sent out a Wailord to deal with them, and one of its splashes sent Ash flying into the air. Dragonair tried to save him from his fall, but its skin was too slippery for Ash to hold on to. As such, it then proceeded to evolve into Dragonite and save Ash. After Team Rocket was defeated, Dragonite expressed its willingness to come with Ash, and he caught it.
In Thrash of the Titans!, Dragonite met Iris, and was quick to give her a big hug. It was later used in a World Coronation Series match against her, battling Iris's own Dragonite. Despite holding its own, Dragonite was unable to match Iris's Dragonite's power and was recalled. Dragonite was later sent back out to battle Haxorus, eventually emerging victorious thanks to Iris' encouragement for it to enjoy battles, and its newly learned Draco Meteor. This win allowed Ash to advance to the Ultra Class.
Much like Ash's Muk, Dragonite is a hugger, often embracing people and Pokémon, even when it is meeting them for the first time. In Caring for a Mystery!, it even tried to hug an un-hatched Egg, forcing Ash to tell it that it shouldn't do so. It also displayed both courage and determination in saving Ash, which gave it the boost it needed to evolve. It cares for its friends, as it didn't hesitate to come to the aid of its Dragonite friend and for Ash.
Like many members of its species, Ash's Dragonite is an adept flyer, and relishes the chance to do so. In Raid Battle in The Ruins!, Ash used Dragonite to help him and Pikachu cross the Desert Resort, and was happy to race with Goh and his Beedrill to see who was faster, becoming so engrossed in the race that it sent Ash and Pikachu flying through the air. Dragonite was overjoyed by its victory, and while it obediently returned to its Poké Ball before Ash and Goh entered the cramped Colossus Ruins, it was visibly disappointed. Dragonite has also been shown to have good instincts as a caretaker, as seen in Panic in the Park!, when it convinced Ash and Goh that the conflict between Goh's Pokémon would be best left for them to solve themselves, while at the same time it made no effort to stop them from trying to intervene. In There's a New Kid in Town!, it was able to stop a crying fit from Goh's Sobble with simply a gentle hug.
Despite its considerable large size, Dragonite is a light eater, seen during the Pokémon Grand Eating Contest, where Dragonite was fully satisfied during the first round of the contest, and was shown to have not even eaten the entirety of the food on its plate.
Dragonite is also an extremely resilient and strong Pokémon, being able to defeat both of Korrina's Pokémon, including her MegaLucario, and withstand a multitude of attacks. In battle, it gains a fierce disposition, indicating a passion for and enjoyment of battling, though afterwards, it will return to its usual happy nature.
Description: A combination of Hurricane and Overheat. Darmanitan uses Overheat while Dragonite creates a Hurricane; the two attacks then combine to create a swirling stream of red-orange fire surrounded by green blades of energy. This was used to incapacitate a wildgiantGolurk in the Colossus Ruins.
Description: Dragonite uses Dragon Dance to not only boost its attack power and speed, but also deflect the opponent's physical attacks. This also makes it spin and complete the dance faster. This was used in Ash's World Coronation Seriesmatch against Korrina.
Description: Dragonite spins around to surround itself in its own Hurricane, creating a spinning barrier of wind that repels attacks. This was used in Ash's World Coronation Series match against Iris at the Opelucid Gym.
