Spider-Man briefly encountered Superman in an episode of the 1981 animated series, paying tribute to their time together in the comics.
In 1976, DC Comics and Marvel Comics jointly published Superman vs. The Amazing Spider-Man: The Battle of the Century, which was written by Gerry Conway and penciled by Ross Andru, with Neal Adams and John Romita Jr. working on uncredited redraws. The unparalleled endeavor brought the two superhero universes together for the first time in an adventure that saw Peter Parker/Spider-Man and Clark Kent/Superman defeating the combined forces of Doctor Octopus and Lex Luthor.
