Millar's body of work in the comic book industry is usually a subject for controversy, since most of his writings are known to be laden not only with political connotations but also gruesome displays of graphical violence. Such examples include scenes in Kick-Ass 2 where the villain known as Motherfucker kills a bunch of kids before he heads out to rape Kick-Ass' alleged girlfriend, and Bruce Banner/The Hulk mating with She-Hulk (his cousin) to create an army of Hulks.
During a talk that allegedly took place on a thread in his own Millarworld forums, Millar stated:
"I pitched this to DC for a laugh years back. The idea was that, like 'Death of Superman', we had 'Rape of Wonder Woman'; a twenty-two page rape scene that opened up into a gatefold at the end just like Superman did."
The comic's idea surfaced around 1993, the year of the mentioned Death of Superman arc as well as the Batman arc Knightfall wlhere the Caped Crusader got his spine broken by Bane and is forced to give the Batman identity to violent anti-hero Azrael as he recovers. Despite Millar saying that the story was just a joke he had made, he mentioned the fact that DC Comics was actually considering publishing the story and already had an artist draw a sketch for the comic's first page.
This was meant to be DC's way of exploring a state of weakness to Wonder Woman in a similar vein to the previously Superman and Batman stories; with the comic starting with Wonder Woman being violated in public. However, the increase of rape allegations in the media at the time and a lot of complaints in both DC's writing and art departments lead to the comic's quick cancellation.
