I would be the friendly , not overly - eccentric and mysterious antagonist who turns out to be a main villain or an anti - hero with religious aesthetics and a morality issue . My introduction scene would start in a mundane location like a school or on a street , where I greet the protagonist and help them out with something before returning to my own business . Then the antagonist reveal would be darker , a murder perhaps , a protagonist who finds out as I slip away .
