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.[1] Draco Meteor was the move that won this contest.[2]
This move being classified as a Dragon-type move is likely a play on its original name, りゅうせいぐん Ryūseigun (Meteor Shower), which contains りゅう ryū (dragon).
