In December 2005, prior to the release of Pokémon Diamond and Pearl, CoroCoro Comics January ran a contest where fans could name the strongest Dragon-type move. Draco Meteor was the move that won this contest.
Its Japanese name, りゅうせいぐん Ryūseigun (Meteor Shower), contains りゅう ryū (dragon), which is likely a play on its Dragon typing.
