Laertes is the son of Polonius and the brother of Ophelia. In
the final scene, he kills Hamlet with a poisoned sword to avenge the deaths of his father and sister, for which he blamed Hamlet. While dying of the same poison, he implicates King Claudius. The Laertes character is thought to be originally from Shakespeare, as there is no equivalent character in any of the known sources for the play.
