When the Man of Steel died defending his adopted home, it seemed that the spirit of truth and justice he represented was extinguished forever. But watching from the sidelines was another Superman—older, wiser, more experienced—with his wife, Lois Lane, and their son, Jonathan Kent.

But he is not the only survivor of Krypton to make the journey to this reality.
