Millar's work in comics are deemed highly controversial, as they usually feature over-the-top violence, use of taboo elements and a lot of graphic content as well as political topics (as seen in Red Son and the Marvel Comics arc "Civil War"). Examples include scenes in Kick-Ass 2 where the villain known as Motherfucker kills a bunch of kids and then 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 and as well as the Batman arc "Knightfall" where the Caped Crusader got his spine broken by Bane and is forced to give the cape and cowl to Jean-Paul Valley, who would later become the violent Azrael. 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 Superman and Batman arcs; this comic would have served as a way to show a more aggressive Wonder Woman after suffering such acts in a similar way to the other arcs. However, the increase of rape allegations in the media and a lot of complaints in both DC's writing and art departments lead to the comic's quick cancellation.
