Superman: Emperor Joker

In 2007, DC Comics released Superman: Emperor Joker, a one-shot by writer Joe Kelly and artist Kano that expands on the classic storyline where the Joker gains reality-altering powers. This single issue serves as a coda to the original tale, exploring the lingering psychological scars on Superman after being subjected to the Joker's nightmarish reign. It stands as a key character study for both the Man of Steel and his greatest foe, examining the aftermath of ultimate chaos.
