Anime


James' Magikarp, which he bought from a dealer, evolves into a Gyarados, which called forth four wild Gyarados to use Dragon Rage and send Ash and co flying.

A Red Gyarados is found in the Lake of Rage, north of Mahogany Town, in Johto. It is owned by the Elite Four, Lance. Lance once use the Red Gyarados to save Brock, May and Max from drowning while he is disguising as a Team Magma grunt. Lance's cousin, Clair the Gym Leader of Blackthorn City also owns a Gyarados and it was used to protect Dratini and its battle against Jessie's Arbok and later teaming up with Dratini who is now evolved into a Dragonair to knock James' Weezing twice using both Hydro Pump and its Hyper Beam and blasts Team Rocket away from Dragonair's Twister. She later uses this in their Gym rematch against Ash as her second Pokemon but lost to his Pikachu.

Misty owns a Gyarados as well who has the same ill-tempered behavior as James' Gyarados but this subsides when it defeats the three brothers' Tentacruel after it attacked Misty to protect Corsola and Gyarados itself while in underwater. In Hoenn, She uses this against Colonel Hansen when Togepi who is now evolved into a Togetic uses its Safeguard to block Shedinja's Solar Beam and it quickly defeats his Pokemon with its powerful Flamethrower which proves to be super effective. It later fights alongside other Pokemon to battle all of the Mirage Pokemon created by Dr. Yung in the movie Master of Mirage Pokemon. In the Sun & Moon series, her Gyarados can mega evolved into Mega Gyarados via Key Stone and it was after Lysandre's Red Gyarados from the XY series. Therefore, it was defeated by Ash's Pikachu from getting massive damage using its Z-Move, Gigavolt Havoc.

In the XY series and like Lance, Lysandre also owns a Red Gyarados but it can mega evolved into a Mega Gyarados via Key Stone which it manage to wipe out all of Ash's Pokemon except Pikachu and Ash's Greninja in its Ash-Greninja form during the Team Flare's crisis. However, Lysandre's Gyarados was ultmately defeated by the combined efforts of Ash's Pikachu, Ash's Greninja in its Ash-Greninja form and Alain's Charizard in its mega evolved form as Mega Charizard X.
