| Fergus' Gyarados|
ウミオのギャラドス Umio's Gyaradosu
|Debut:||Mewtwo Strikes Back|
|Current location:||With Fergus|
Fergus first used Gyarados to bring him to New Island. It was later seen in the pond inside the castle when Fergus introduced his Pokémon to Ash Ketchum and his friends. When Mewtwo insulted both humans and Pokémon, Fergus was insulted by that statement. Fergus ordered his Gyarados to use Hyper Beam on Mewtwo but Mewtwo deflected the attack. Gyarados was then hit by its own attack and was damaged badly by the attack, leaving Fergus worried at his Pokémon. Gyarados was later captured by Mewtwo by using the Mewtwo Ball. It was later freed by Ash along with the other Pokémon and it started to battle against the Gyarados clone.
