Latias and Latios are Pokémon species in Nintendo and Game Freak's Pokémon franchise. Created by Ken Sugimori and solely based on traditional European dragons but with the added features of jet powered aeroplanes as he states in a number of interviews, Latias and Latios first appeared as central characters in the film Pokémon Heroes, and later appeared in the video games Pokémon Ruby and Sapphire, also appearing in various merchandise, spinoff titles and animated and printed adaptations of the franchise. They are voiced in Japan by Masashi Ebara and Megumi Hayashibara respectively.
