Dark Horse Comics is the largest independent American comic book publisher. Mike Richardson, the owner of several comic book shops in the Portland, Oregon metropolitan area, began to publish in 1986 with an anthology series called Dark Horse Presents, investing profits from his stores into Dark Horse Comics. Dark Horse publishes many licensed comics, including comics based on Star Wars, Buffy the Vampire Slayer, Aliens, Predator and Who Wants to be a Superhero? Dark Horse also publishes creator owned comics such as Frank Millers Sin City and 300, Mike Mignolas Hellboy, Stan Sakais Usagi Yojimbo, Katsuhiro Otomos Akira and Michael Chabons The Escapist. Today, the comic arm of the company flourishes despite no longer having their own universe of superpowered characters.
