Peripeteia considered complex and superior to simple plots without anagnorisis or peripeteia, such as when Medea resolves to kill her children, knowing they are her children, and does so. Aristotle identified "Oedipus Rex" as the principal work demonstrating peripety. (See Aristotle's "Poetics".) In Sophocles' "Oedipus Rex", the peripeteia occurs towards the end of the play when the Messenger brings Oedipus news of his parentage. In the play, Oedipus is fated to murder his father and marry his mother. His parents, Laius and Jocasta, try to forestall the oracle by sending their son away to be killed, but he is actually raised
Jocasta (comics) about to do. Jocasta was granted provisional status with the team. During this period, she aided them against threats such as the giant robot Red Ronin, the Yellow Claw, the Berserker, Pyron, and the second incarnation of the Brotherhood of Mutants. At one point, she was electronically deactivated by Iron Man under control by Ultron, but she was reactivated following Ultron's defeat. Jocasta did not believe she was accepted by most of the Avengers, and she was never officially inducted into the team. After she singlehandedly defeated a rogue sentient weather satellite, she left the Avengers following a membership reorganization.
