A legend was reborn in BIG BANG COMICS #23 as a successor assumed the mantle of the Sphinx!
Peter Chefren was a genius, inventor, industrialist and one of the world’s richest self-made men. He was also known to the world as the super hero the Sphinx. What nobody knew was that Chefren was not of this Earth, but a refugee from a parallel dimension. When that past caught up to him (in Big Bang #13) Peter Chefren returned to his own dimension to close the dimensional gateway and protect this Earth from invasion by his own people.
