The Sphinx is the name of two fictional characters that appear in comic books published by Marvel Comics. The first version of the Sphinx first appeared in Nova #6 (Feb. 1977) and was created by Marv Wolfman and Sal Buscema. The second version first appears in New Warriors #4 and was created by Fabian Nicieza.

Anath-Na Mut is a magician in the court of Egyptian pharaoh Ramesses II. Defeated in a duel of magic by the prophet Moses, the magician is exiled into the desert for his failure. The title Nova recounts in flashback how Anath-Na discovers the alien Ka Stone, which grants him immortality and a host of other powers. Using the alias the Sphinx, Anath-Na wanders the Earth for thousands of years, and eventually becomes bored with his immortality. After learning the origins of the hero Nova, a human empowered by the aliens of the planet Xandar and possessing the subconscious knowledge of Xandar's Living Computer, the Sphinx theorized that the machine may be able to find a way to end his immortal life.

In a Fantastic Four annual, the Sphinx empowers a pawn called Thraxon to help subdue the Inhumans, as he plans to use the power of ruler Black Bolt to amplify a scanning device and read the minds of all mankind for knowledge of how to finally die. Superhero team the Fantastic Four defeat Thraxon and in a final confrontation Black Bolt blasts the Sphinx into deep space. The character reappears in the title Nova, taking mental control of Nova and with his temporary allies (Comet; Crimebuster; Diamondhead; Powerhouse and Doctor Sun), they travel back to Xandar to join a war against the invading Skrulls.

The story continues in the title Fantastic Four, where this proves to be a ruse, as once on Xandar the Sphinx takes advantage of the war to find and absorb the knowledge of the Living Computer of Xandar. Evolving into a god, the Sphinx decides to destroy Earth. The Fantastic Four witness this, and knowing that they are outmatched Mister Fantastic contacts the cosmic entity Galactus and presents a proposal — if Galactus will defeat the Sphinx, then Mister Fantastic will release him from his vow to never threaten the Earth again. Galactus accepts, and after the Fantastic Four find Galactus a new Herald (Terrax), the group travel to Earth. Galactus defeats the Sphinx, and after crushing his Ka Stone sends him back in human form to ancient Egypt. The character is trapped in a time loop, forcing Anath-Na to constantly relive his life to this point.

Sphinx has not been a contender in any CBUB matches.
