@fer1323 If he's a faunus (of any fraction), he would know it, as he would have variant biology to some degree. Ears, tail, fangs, eyes, etc.Of course, if they are part human it is possible they wouldn't manifest any faunus traits or abilities,in which case being a hybrid is only relevant if they have children, or if I decide to make plot crap happen relating to it. In the event he doesn't manifest faunus traits, then it would be fine for him to not know his heritage.
