The Sphinx (Anath-Na Mut)

The man who would become the Sphinx was the chief wizard in the court of the ancient Egyptian Pharaoh Ramses II, and in fact a mutant.[1] When the wizard's apparent magical abilities proved to be inferior to the powers demonstrated by Moses the leader of the captive Israelites, Ramses banished the wizard. After years of wandering, the wizard happened upon a temple of unknown origin, inside which was the mystical Ka stone. The mystical stone seemed to bid him to touch it to his forehead. The moment he did so, the stone affixed itself to him and imbued him with vast superhuman powers and immortality. The wizard assumed the name of the Sphinx and spent the next 5,000 years traveling the Earth without purpose, involving himself in whichever endeavors of mankind struck his fancy.

He has faced numerous heroes in the Marvel Universe yet he has been, chiefly, an antagonist of Nova.
