Superman Man Of Steel #4 1989

In Superman: The Man of Steel #4, Lois Lane and Clark Kent attend a lavish party on Lex Luthor's luxury liner. The event turns chaotic when terrorists hijack the ship, forcing Clark to reveal himself as Superman to save the passengers. It's soon revealed that Luthor orchestrated the entire incident, attempting to strong-arm Superman into working for him. Superman's refusal solidifies Luthor's intense hatred, marking a pivotal moment. This issue is highly notable to collectors as it features the first full appearance of the post-Crisis Lex Luthor, reimagined as a ruthless billionaire.
