Who is Batman's #1 enemy?

Batman's Greatest Enemy was never The Joker. It's Batman's undisputed number one enemy is The Joker. Acting as Batman's polar opposite, The Clown Prince of Crime is a chaotic mastermind who exists to challenge Batman's rigid moral code and sanity. Other prominent villains like Ra's al Ghul ( Who challenges Batman's methods and legacy ) and Bane ( The only villain to permanently break Batman's back and temporarily "defeat" him ) are top-tier threats, but The Joker remains the definitive archenemy.
