the lone resident of the ruins of Alexander's palace, the aged Aga (Alan Napier), that Sinbad is his lost son, owing to a medallion Sinbad had since childhood. When the Emir threatens to kill Sinbad, Sinbad confesses his true identity as just a sailor. Nevertheless, Aga capitulates and shows them the fabulous treasure's hiding place. He later informs Sinbad that he had given his son to sailors to shield him from treasure hunters; Sinbad is indeed his son and the true Prince of Daryabar. When it is discovered that Jamal had intended to poison the Emir and his crew to have the treasure to himself, the Emir forces him to drink the deadly liquid himself. Sinbad escapes again, boards the Emir's ship and frees his crew. The Emir is killed by Greek fire catapulted at him from his own ship.
