Question: What is the name of this fictional supervillain appearing in American comic books published by DC Comics that Clark Kent fights in New York in the novel "It's Superman!?"
Sentence (from "It's Superman!"): Despite the setting, this is not about the Golden Age Superman also known as the Superman of Earth-2; as Perry White, the Daily Planet, Lex Luthor's position and his trademark powers (including flight) are not part of that alternate Earth.
Relevant evidence: No
