Joker's Beatdown

After taking control of Black Mask's gang, taking over Blackgate Prison 2 times, robbing the Gotham Merchant's Bank, the destructive skirmishes at the Royal Hotel, forcing Batman into a moral dilemma to kill him, Bane, or himself, and ultimately calling Batman "meat-for-brains", Batman goes all Star Platinum on the Joker, giving him one of the most ferocious beatdowns in the Batman universe, IN THE MIDDLE OF A CHAPEL.
