When Supernatural went off the air, it had 327 episodes over the span of fifteen seasons. With the show gone, fans might be looking for something to take its place, and luckily, there are some great comic books and graphic novels that can fill that hole.

Horror comics are nothing new seeing as horror titles in EC Comics dominated sales before superheroes came back into style in the '60s. Since that time, there have still been some great supernatural comic books hitting the newsstands, and many of them stand up well with the themes and subject-matter that fans loved so much in Supernatural.

American Vampire

Supernatural dealt with many different monsters, but outside of demons from Hell, there wasn't anything bigger than vampires for Sam and Dean Winchester to hunt down. For anyone who wants to read a vampire comic book that takes the tired clichés and turns them on their heads, check out American Vampire by Scott Snyder and Rafael Albuquerque.

The main vampire here is Skinner Sweet, a vampire who can walk in the day and battles vampires, all of whom have taken over America by operating behind the scenes in Hollywood and politics.

Ghost Riders: Heaven's On Fire

Ghost Rider has always been one of Marvel Comics' most popular supernatural series. The original had a stunt cyclist named Johnny Blaze who sold his soul to the devil to save his dad, only to have the devil deceive him, leaving his dad dead and Johnny stuck with a demon inside him.

This particular series is 2009's Ghost Riders: Heaven's on Fire by Jason Aaron and Roland Boschi, and they pull a story right out of Supernatural as Johnny Blaze and the man who followed him as Ghost Rider, Danny Ketch, have to team up when a demon takes over Heaven and conquers it.

Gotham By Midnight

While Batman mostly deals with more run-of-the-mill criminals, he does not deal with the supernatural well. It's a good thing then there was a unit that did deal with the supernatural in Gotham City.

This unit is led by none other than Detective Jim Corrigan, who most DC fans know as the Spectre. This is basically Gotham P.D. mixed with the X-Files, as they hunt down and deal with demonic evil that Batman wants nothing to do with. This all comes from horror writer Ray Fawkes and artist Ben Templesmith.

Hellblazer

If there is only one comic book that a person who loves the demonic monster hunting and purging in Supernatural, that comic book should be Hellblazer. This is not the Constantine books DC Comics is releasing now, but the original Vertigo titles.

John Constantine is a man who is damned, but he has also made very sure that Hell can't take him, while Heaven doesn't want him. Through it all, he is trying to atone for everything he has done wrong in his life. Hellblazer was created by Peter Milligan and Giuseppe Camuncoli and ran from 1988-2013.

Locke & Key

One of the big stories in Supernatural is that Sam and Dean Winchester were two boys whose mother died after a mysterious demon attacked her. They were left with their father, who trained them to hunt monsters before disappearing himself.

Locke & Key, by Joe Hill and Gabriel Rodriguez, was a 37-issue comic book series about three siblings whose father was murdered. They learned he was hiding a big secret in the old family house with keys that could open up abilities and a demon that wanted them.

Buffy The Vampire Slayer

Supernatural took over the TV spot of the Buffy the Vampire Slayer spinoff series Angel with the same basic genre. They are all urban fantasy series about people fighting the monsters that hide in the dark.

For fans who miss Buffy, the show was continued in comic book form with extra seasons following its television finale. There is a lot of great stuff for fans of the show here, with seven full Omnibus collections, as well as a newer reboot comic series.

Justice League Dark

The Justice League of America is a superhuman team in DC Comics that deals with threats to Earth that no one hero can hope to stop alone. However, while that team has the big guns to deal with alien threats and other superhuman beings, they are not fully capable of supernatural threats.

That is where Justice League Dark comes in. Created by Peter Milligan and Mikel Janín, this team consists of mystical heavyweights like Constantine, Zatanna, Swamp Thing, Deadman, Etrigan, and more.

B.P.R.D.

The Bureau for Paranormal Research and Defense (BPRD) is part of the world of Hellboy, created by Mike Mignola.

This is a spinoff from the Hellboy series and focuses more on the team's focus on dealing with supernatural threats, often working with governments of the world, of which it has a strong relationship. This team includes Hellboy, Abe Sapien, Liz Sherman, and they have saved the Earth more times than people can count from supernatural threats.

October Faction

October Faction was one of the lesser-known supernatural comics until a single-season Netflix series arrived.

Created by Steve Niles and Damien Worm, October Faction is about a retired monster hunter named Frederick and his wife and two kids. When they return home, they realize that it is impossible to retire from the family business when there are clearly still monsters running loose and the entire family gears up to take down the evil creatures once again.

Supernatural

For fans who miss Supernatural, don't ignore the fact there are some great Supernatural comic books and graphics novels to continue the story and learn a little more about the past.

Supernatural Origins is what it claims to be, with John Winchester out there hunting demons years before his sons grow up. Other options include Supernatural: Rising Son, Supernatural: Beginning's End, and Supernatural: The Dogs of Edinburgh.
