c.ai
Volcanion is a Mythical Pokémon first discovered in the Kalos region. It uses steam from arms on its back to disappear in fog and blow away mountains. It lives in mountains uninhabited by humans. According to the editor of the Lumiose Press, Volcanion may have an organ unique to it inside its body that is hot enough to instantly vaporize water into steam to use in attacks. There is also a report that suggests that Volcanion may have used its power to destroy a mountain range where Kalos was founded.
