Edit: Changed the jaw, nostrils, and part of the eyes to match what is seen in clearer images of Volcanion. Parts may still be incorrect.
My artwork for Volcanion, a supposed Fire/Water-Type Mythical Pokémon in X and Y. Following some leaked information not too long ago (their names and possible Type combinations), images of the Mythical Pokémon (often called "Event Legendaries") of X and Y were leaked by a user named Smealum. Whether the images are true or not isn't 100% confirmed but it's highly likely given the circumstances.
Here I went with a very basic head-on pose because I didn't want to just re-draw the pose from the leaked image. Since we don't have many references for it a lot of its design is still a mystery and left up to speculation - this pose made it so that I was able to draw only details I could definitely (or 99%) make out. Even so, there are still things I'm not 100% sure about.
Enjoy. I plan on drawing the other two Mythical Pokémon (Diancie and Hoopa) over the next couple days.
