Neither Batman nor Superman were the first superheroes, but they are both considered to be among the greatest of all time. Over the decades, Batman has seemingly surpassed Superman in popularity. But on the printed page, it’s the Man of Steel who has the distinction of being the first to appear. Superman made his debut in Action Comics #1 in 1938, while Batman premiered the next year in Detective Comics #27. In fact, Bill Finger and Bob Kane reportedly created Batman in response to Superman’s success. So without Superman, there would be no Batman!
