Latias and Latios
Latios (ラティオス, Ratiosu) and Latias (ラティアス, Ratiasu) are Pokémon species in Nintendo and Game Freak's Pokémon franchise. Created by Ken Sugimori, Latios and Latias 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.
Known as the Eon Pokémon, Latios and Latias are two legendary Pokémon originating from the Ruby, Sapphire, and Emerald series of games. They are male and female respectively, and the first legendary Pokémon to have genders. While Latias is red and white, Latios is blue and grey, as well as being larger and more angular. While Latios and Latias have received significant criticism for their role in the film Pokémon Heroes, critics citing their voices as well as Latias' human transformation, they have received positive reception for their role in the video games. In the Pokémon Omega Ruby and Pokémon Alpha Sapphire releases, Latios and Latias are given Mega forms.
