He was shown as dying during Crisis on Infinite Earths, although this has been retconned twice to fit in with the later revelation that he was a reincarnation of Prince Khufu — who would later be reincarnated as Carter Hall, the Golden AgeHawkman. Current continuity has it that he was shot by a criminal named Matilda Roderic, who was presumably a reincarnation of the evil priest Hath-Set, who is apparently destined to kill Khufu in every life. Roderic's descendant is the current Hath-Set. The 2002 retcon also revealed he was the partner and lover of the Western heroine Cinnamon, who was the reincarnation of Khufu's wife Chay-Ara. Nighthawk appears in Guy Gardner #24 during the "Zero Hour" incident. He sported white sideburns at this point in time.
