Since this is in the “features” section, You need to change your title to something like
“Clothing: Fantasy Monsters” so that they don’t lock and send you a message telling you that the title format is wrong and needs changed.
I understood everything you said. There’s a part of your story where you want mythical/fantasy/sci-fi -ish monsters and you’re correct in the fact that there aren’t anything like that in the portal.
I personally support the idea of getting monsters/monster-like clothes. They would make the horror/thriller and fantasy writings much more awesome if the bad guy was in full Frog Monster gear instead of having weird green skin and a tailcoat. 
edit to add:
Something I’ve seen people do (besides changing skin colors and telling readers "this is X-type monster characterized by (insert features) ), is use overlays in place of actual characters. Obviously, this can look a little awkward if you can’t find several different frames and animate them but it’s an option.
