Kratos surprises Zeus, seizes the Blade of Olympus, and finally incapacitates him. Athena intervenes and implores Kratos to stop, as by killing Zeus, he will destroy Olympus. Kratos ignores her and tries to kill Zeus, but Athena sacrifices herself by impaling herself upon the blade, granting Zeus' escape. Before she dies, Athena reveals that Kratos is actually Zeus' son. Zeus was afraid Kratos would usurp him, just as Zeus had usurped his own father, Cronos. Kratos declares that the rule of the gods is at an end, then travels back in time and rescues the Titans just before their defeat in the Great War. He returns with the Titans to the present, and the gods watch as their former foes climb Mount Olympus. Kratos, standing on the back of Gaia, declares that he has brought the destruction of Olympus.
