Cheops
Cheops
The second Pharaoh of the 4th dynasty of Egypt, who reigned ca. 2590-2567 B.C. He was the builder of the Great Pyramid at Giza, the largest single building ever erected in ancient times. It has been calculated that 100,000 men working unceasingly would have required twenty years to complete the task. Superman met the great pharaoh and helped to complete construction of his gigantic pyramid --single-handedly performing well over half the work--during a time-journey [see Time Travel] to Egypt in the twenty-sixth century B.C. (WF No. 32, Jan/Feb 1948: "The Seventh Wonder of the World!"). (TGSB)
Ironically, the immortal villain Vandal Savage claims that he was Cheops in an adventure with the Green Lantern (Alan Scott), though the chronicles alone may not be able to substantiate the validity of the claim or whether it took place in an alternate reality.
