I think I'd use him for a horror story where he can travel dimensions in order to collect his victims. Somewhat in a Cabin in the Woods way. Maybe he'll just be an annoying demon that happens to be rich! (Bill Cipher ish? Type of annoying) Though I also like the idea that he'd be a God of some kind. He builds homes for the homeless but just looks hella rad/"evil". Has a taste for clothing & cars no matter what though.
