- This article is about the character. For the guest star, see Alan Moore.
Alan Moore is an English writer known for work in comics, including the acclaimed comic book series Watchmen, V for Vendetta, From Hell and Batman: The Killing Joke.
When Coolsville Comics & Toys becomes popular, Alan Moore, along with Art Spiegelman and Daniel Clowes, come to the store for a comic book signing. Comic Book Guy jealously tries to sabotage Milo's popularity by pointing out his girlfriend and bribing the children with "Japanese weapons". When these plots do not work, Comic Book Guy tries to use the weapons to destroy Coolsville, but is subdued by Alan and the other authors, who remove their shirts to reveal muscular superhero physiques.
During the autograph session at Coolsville, Milhouse asked Moore to sign a copy of Watchmen Babies in V for Vacation. Moore signed the comic for Milhouse, but was evidently not pleased about having been involved in that project. He started to go off into a tirade, but read a Little Lulu comic to calm himself down.
