When Hack saw how much money the superhero movie Deadpool & Wolverine was making at the box office, he decided to pen a mash-up of the X-Men anti-hero with ILoveYouMan, the superhero with super bad breath created by his cover artist Jonny M.
As is typical with Hack, he didn’t bother to acquire the rights to either hero before publishing the novel (Jonny makes so many covers for Hack’s book that he didn’t realize Hack was ripping him off until it was being printed) and was promptly sued by both Marvel and Jonny, resulting in almost every copy being pulled from circulation.
It’s a pretty compelling read if you can get your hands on it.
