Bane's search brings him back to Santa Prisca. In search of leads, Bane questions the Jesuit priest who had taught him while he was in Peña Duro. The priest explains that there were four men who could possibly have been his father: a Santa Priscan revolutionary, an American doctor, an English mercenary, and a Swiss banker. While searching for the Swiss man in Rome, Bane encounters Talia al Ghul and the League of Assassins and eventually impresses Ra's al Ghul so much that he chooses Bane to marry Talia and become his heir. Ra's also has discovered Bane's father's identity, but did not reveal this information to him. Ra's al Ghul then launches a plague attack on Gotham in the "Legacy" storyline, with Bane at his side, who is posing as Ra's al Ghul's henchman Ubu. Batman gets his rematch with Bane in "Detective Comics" #701 and finally defeats him in single combat. Disappointed by his protegé's failure, Ra's calls off the engagement to Talia and disowns Bane.
