Superman's 10 Most Dangerous Villains Who Could Kill Him

ComicBook.com breaks down a gallery of Superman's most lethal adversaries—the ones who've actually posed genuine extinction-level threats to the Man of Steel. The list apparently includes at least one villain who has legitimately killed Superman (probably Doomsday, though worth noting the article doesn't spoil which one). Over decades of publication, Superman has accumulated a rogues gallery that spans threats from pure physicality to cosmic-level power and psychological warfare. The premise acknowledges that while Superman seems invincible, his villains have earned their stripes by pushing him to the absolute brink.
