Mike Mignola's fascination with ghosts and monsters began at an early age; reading Dracula at age twelve introduced him to Victorian literature and folklore, from which he has never recovered. Starting in 1982 as a bad inker for Marvel Comics, he swiftly evolved into a not-so-bad artist. By the late 1980s, he had begun to develop his own unique graphic style, with mainstream projects like Cosmic Odyssey and Batman- Gotham by Gaslight. In 1994, he published the first Hellboy series through Dark Horse.

There are thirteen Hellboy graphic novels (with more on the way), several spinoff titles (B.P.R.D., Lobster Johnson, Abe Sapien, and Sir Edward Grey- Witchfinder), prose books, animated films, and two live-action films starring Ron Perlman. Along the way he worked on Francis Ford Coppola's film Bram Stoker's Dracula (1992), was a production designer for Disney's Atlantis- The Lost Empire (2001), and was the visual consultant to director Guillermo del Toro on Blade II (2002), Hellboy (2004), and Hellboy II- The Golden Army (2008). Mike's books have earned numerous awards and are published in a great many countries. Mike lives in Southern California with his wife, daughter, and cat.

Evan Dorkin (born April 20, 1965) is an American comics artist and writer. His most well-known works are the comic books Milk and Cheese and Dork. His comics often poke fun at fandom, even while making it clear that Dorkin is a fan himself. As well as his comics work, Dorkin has also written for animation, including (with his wife Sarah Dyer, also a comics writer/artist) Space Ghost- Coast to Coast.

He also wrote and produced Bring me the Head of Boba Fett, an animated television pilot for Adult Swim called Welcome to Eltingville, based on his own characters. Dorkin and Dyer also wrote some episodes of the Superman animated series, particularly the episode "Live Wire," which introduced a new character of the same name.

Additionally, the pair contributed to the script of the 2006 English-language version of the anime Shin Chan. After an initial six-episode order proved successful, more episodes were ordered, but Dorkin and Dyer are no longer working on the series. Dorkin has been the recipient of several Eisner Awards, including 2002's Best Writer/Artist- Humor.
