Dragonite was seen by Ash and his friends flying around the island where the battle against Drake would take place. It also easily defeated Team Rocket with Hyper Beam.
When Ash battled Drake, Dragonite was the last Pokémon Drake used and defeated Ash's Charizard, Ash's Tauros and Ash's Squirtle before Team Rocket attempted to capture it. Dragonite effortlessly broke the net and smashed through Team Rockets balloon sending them blasting off. It then battled Ash's Pikachu, but Pikachu managed to defeat it by using Thunder whilst positioned on Dragonite's head.
