Even though AMC's The Walking Dead hit screens all the way back in 2010 with that iconic first episode of Rick Grimes waking up from a coma in a hospital crawling with walkers, its comic book series predates the beloved post-apocalyptic series by six years. Created by Robert Kirkman, the comic series was initially going to be a follow-up to George A. Romero's Night of the Living Dead and taking part in the 1960s, but Kirkman and artist Tony Moore decided to swerve that idea for a more modern take on the zombie genre.
The Walking Dead not only had some of the best and most harrowing storylines seen on TV at the time, but its incredible cast helped piece its narrative into something truly special. Taking many aspects from the original comic series, the zombie survival show saw many acclaimed moments that went down in TV history, like the shocking scene surrounding the birth of Judith, Carl getting shot in the eye, Rick revealing what Dr. Edwin Jenner had told him to the group and poor Hershel getting beheaded by Michonne's katana, but one particular savage Rick moment posed a problem later on for Robert Kirkman with how he would continue with his story.
