Randis Albion is an artist whose work is all over the place thematically, but constantly awesome. As a conceptual concept artist working heavily in Adobe Photoshop, he has designed works for video games and other media.
It's extremely tough to pick just one example of his work, but the Pikachu piece "Gonna Catch 'em All", above, is one of his newest. More to see at the slightly NSFW link.
