As long as any official names weren't used or any content copied straight, there shouldn't be any problem with any kind of fan art, be it porn or something else. I don't think creating art inspired by something itself is a problem no matter what kind of art it is. But if some names (e.g. Pokémon) were used without permission or if any content (such as models, textures etc.) were directly stolen, this is obviously justified.
