Trivia

 * Despite its dragon-like appearance, it isn't -type, yet it learns Dragon Type moves such as Dragon Rage and Dragonbreath and is used by many Dragon Trainers such as Lance and Clair.
 * Despite it being a -type, it can only know one Flying-type move, Bounce.
 * Despite it being seen flying in the anime, it cannot learn the move, Fly,and this is only because it's pre-evolution,Magikarp can learn it in Generation IV only.
 * Gyarados may be based on the mythological creature, the Kraken, since it's original name was going to be Skullkrakon.
 * In Generation II and IV, Gyarados is the only 100%-certain shiny encounter and the first of only two shiny Pokémon to be integrated into a game's plot (the second was Celebi in Pokémon Mystery Dungeon: Explorers of Time and Explorers of Darkness)
 * Gyarados being evolved from Magikarp, which is a useless and weak pokemon, is a reference to a common belief in Asian countries that a carp will transform into dragon after it passes through hard ordeals
