Artist Coran "Kizer" Stone is the man to thank for these pieces of Pokémon art, which include trainer Ash getting a little surly and a struggle with a monster that has trouble keeping his bodily functions in check.
If you like what you see, you should check out Stone's deviantArt page, which has not only more video game art on show, but some great comic book stuff as well.
