The Walking Dead comic book series created by Robert Kirkman, captured the imaginations of readers with its post-apocalyptic narrative. However, the characters of Daryl and Merle Dixon, who would later gain popularity in the TV adaptation, were not part of the original comic's storyline. Norman Reedus's portrayal of Daryl became a fan-favorite, leading to the character's solo spin-off series titled The Walking Dead: Daryl Dixon, where he embarks on a new chapter in France, searching for his former allies, Rick and Michonne, amidst human and undead threats.

Robert Kirkman, in reflecting on the creative process, acknowledged the collaborative effort that brought the Dixon brothers to life. He shared in The Walking Dead Deluxe #67 (via ComicBook) how various writers, including Jack LoGiudice and Charles H. Eglee, played a role in developing these characters. According to Kirkman, what makes the TV adaptation unique is the dynamic relationship between the actors and their characters.
