Well, if they do make a Nightmare Foxy, then I can only imagine what they'll do for it. Foxy has always been the most damaged out of the set, and these things are already as damaged as we've ever seen. What more can they do except make him a barely intact half-pure endoskeleton and his destiny of being merged with Mangle is realized. Of, for shits and giggles, they could also switch it around and have him for some reason be the ONLY one that's perfectly preserved
