"Hank Henshaw's body died when his spaceship crashed, but the astronaut learned to "live" in machines of any kind. Combining technology with Kryptonian biology, Henshaw became the Cyborg Superman, convincing many that the Man of Steel had returned from the dead. When the real Superman returned, he defeated the Cyborg, but not before Coast City was destroyed, killing millions! [It is also uncertain that Henshaw is gone for good.]" *Source: Card Back
