Both studied abroad. Both got into trouble with the religious orders. Both had a foe who was a priest, who was in love with their girlfriend. Both had a girlfriend who was the daughter of a priest. Both "died" in a lake. Both their girlfriends were raped in a temple/convent by their enemy priest. Both returned to their country to seek revenge/justice. Both returned under a different identity: Imuthis became "The Sphinx" while Ibarra became "Simoun".
