Iris's Dragonite is the fourth Pokémon that she obtained.
Dragonite first appeared in BW091, where it was fighting with a Hydreigon in Undella Town. It was injured in the battle and caused a blackout when it crashed into a power station. Officer Jenny thought is was on purpose and began pursuing it along with several trainers. Iris didn't believe that the Dragonite caused the blackout and used her ability to read Dragonite's heart, discovering the truth that the blackout was indeed an accident. After protecting it and clearing it of all accusations, it allowed Iris to capture it.
Iris used it in the Pokémon World Tournament in BW092 against Georgia's Beartic. It started to disobey Iris during its battle with Georgia's Beartic, but it was made obvious that it is a skilled battler, easily fending off Beartic's attacks despite the type disadvantages and defeated it with a single ThunderPunch.
Dragonite was used again in BW093 againset Dawn's Mamoswine. Again it had another type disadvantage simply dodging Hidden Power but is still disobeying Iris again enduring Ice Shard and when Mamoswine used Take Down, Dragonite grabbed its tusks and tossed the Twin Tusked Pokemon to the ground. It learned Dragon Rush and knocked out Mamoswine pushing Iris into the semi-finals.
Dragonite was used in BW094 against Ash's Krokorok. Dragonite, like in its previous battles quickly took lead, but Krokorok evolved into Krookodile. Using its newly learned Dragon Claw, Krookodile defeated Dragonite, knocking Iris out of the tournament.
Dragonite is the first Pokémon not native to Unova to be owned by a main character in the Best Wishes series, excluding Pikachu.
Dragonite is the second Dragon-type Pokémon to be captured by Iris, the first being Axew.
Dragonite is the second fully evolved stage 2 Pokemon to be caught by a main character, the first was Dawn's Togekiss (although it was a gift from Princess Salvia).
Dragonite is the only Pokemon that Iris owns that does not begin with a vowel.
Dragonite is the second member of Iris' team to disobey her commands, the first being Excadrill. However, unlike Excadrill, who thought that Iris didn't care about it, Dragonite does not have any obvious motive for disobeying Iris except possibly its own arrogance.
Dragonite's eyes strangely resemble the Dragonite's eyes in Great Bowls of Fire when it went on rampage
