Iconic comic book writer Alan Moore, the mind behind V for Vendetta, Watchmen, and The League of Extraordinary Gentlemen, says he’s retired from the comic book industry. According to ScreenRant, the legendary writer officially retired after the release of the final issue of The League of Extraordinary Gentlemen, Volume IV: The Tempest (July 17th).

The release of the final installment for The League of Extraordinary Gentlemen, Volume IV: The Tempest concludes a 20-year run for the comic book series as well as Moore’s influence within the comic book community. Moore began the comic book project with artist Kevin O’Neill in 1999. The story includes several famous fictional characters such as Dr. Jekyll, the Invisible Man, and Professor Moriarty from Sherlock Holmes.

Moore began his writing career in the late 1970s and gained recognition for his published works in comic strips featured in 2000 AD and Warrior magazines. His career ended up bringing him to DC Comics where he worked on stories for the Caped Crusader like Batman: The Killing Joke as well as Superman. His work also led to him developing the character Swamp Thing.

However, his most popular comic creation may be Watchmen, which explores a darker side to heroes and how the people they save view them and their abilities.

Several of Moore’s works have been brought to the big screen over the years. Such creations were The League of Extraordinary Gentlemen, which may have not have been well-liked at the box office and Watchmen, which is also being developed into an HBO series. More recently, DC Comics has brought Watchmen into their superhero universe alongside familiar characters in the Doomsday Clock series.

How long Alan Moore stays in retirement is another story. He may end up jumping back in here and there to write more stories in the future but that remains to be seen.
