Pokémon Mystery Dungeon
Gyarados makes many appearances outside of the main series, including appearances in "Pokémon Snap", "Pokémon Trading Card Game", "Pokémon Mystery Dungeon: Blue Rescue Team" and "Red Rescue Team", "Pokémon Ranger", and "Pokémon Go". In , a Gyarados appears in the Miracle Sea. He attempts to take control of Phione, but is halted by the player's team. In "", Gyarados tries to take over the Beach Zone in Empoleon's absence, and is the host of a mini-game called "Aqua Dash". In "Pokémon Go", Gyarados is generally considered one of the most difficult Pokémon to obtain - it must be evolved from a "Magikarp" (much like other Pokémon games) and requires 400 Magikarp candies to evolve, more than any other Pokémon in the game. In "Pokkén Tournament" and "Pokkén Tournament DX", Gyarados has been shown in the Magikarp Festival as one of these arenas as only a background character, spectating a battle between the playable fighter Pokémon.
