Since I own absolutely no rights to Pokemon, I can't stop you from using this artwork. I only require credit when it's used on something posted on deviantArt or if it's something you would usually type the credit on (like a fake Pokemon card). If used for avatars, signatures, banners, I don't require credit, but you can credit me if you want. I enjoy seeing anything made with my work. You don't need my permission, but I would like to see what you do with it. :) Copyright Pokemon/Nintendo.
