This issue collected various stories featuring the Joker as a guest star during the bronze age period. It is most noticeable however for including a previously unpublished story originally created for the short-lived comic book series “The Joker”, that was published between 1975 and 1976. The series was cancelled with #9 but this never before seen #10 was set to be the first of a three-parter in which the Clown Prince of Crime was going to take on the Justice League.
Wonder Woman’s death in this story is surprisingly grim for a comic book which, at the time, was still considered a humble kids book.
When an Arkham doctor orders that Joker undergo psychotherapy to remove his pathological tendencies, the Joker makes a deal with the devil to avoid his fate. He agrees to kill the Justice League, because they might distribute an immortality serum that “Lou Cipher” says will be bad for his business.
Joker then proceeds to carry out his task. Green Arrow is hit in the chest with an arrow doctored with Joker venom; Black Canary has her sonic cry turned back on her; the Flash laughs himself to death in super-speed and Wonder Woman is hanged from the Statue of Liberty by her own Golden Lasso!
The issue ends on a cliffhanger promising to introduce us to the Joker’s father.
