Karim is a Saracen and a member of the Black Knights. He takes the role of the "prince" in the parlay with King Richard, though really it is all a plot in which he is supposed to kill Richard. He is foiled when Robin intervenes, taking Richard's place in the parlay and fighting Karim, who loses and flees the scene. When he attempts to kill Robin from behind, King Richard himself chucks his sword at Karim, killing him.
