An alias that is assumed by a resurrected Cleopatra during an encounter with Superboy in a 1969 chronicle. In this disguise, the ancient queen is disguised as a visiting student from modern Egypt. She hatches a complex plot to deceive the hero into believing that he has accidentally killed a fellow student at Smallville High School, and is thus forced to leave the Earth, enabling her to become queen once more. This plan is thwarted when the Boy of Steel realizes that he couldn't have killed Cleop as she had already been killed thousands of years ago by an asp in ancient Egypt (SB No. 160, Oct 1969: "I Chose Eternal Exile!").
