Boss Biggis is a slavedriver of camp outside of Gotham. He sends his henchmen to kidnap homeless people and forced them into slavery. In one instance, his henchman brought in Gaff Morgan (Batman in disguise but has an amnesia). Biggis locks up disobedient slave in boxes. After Bruce remembered he was Batman, he freed himself and went after Biggis shortly after defeating Biggis men. Biggis was later taken to custody.
He is usually seen eating something.
