Daryl Dixon is exclusive to the continuity of The Walking Dead television series and did not originally have a counterpart in The Walking Dead comic book title by Image Comics. However, series creator Robert Kirkman has stated that due to the popularity of the character on the television series, he intends on introducing him into the comics as well.
An April Fool's joke surfaced in 2014 that claimed Daryl would be featured in Issue 129 and even had a cover to back this up. However, the cover was really just an altered version of Dwight from Issue 98 and the real 129 cover just featured Rick Grimes' arm and cane along with several zombies.
Actor Norman Reedus, was voted one of three breakout TV stars to watch in 2011 by Entertainment Weekly readers' choice, owing largely to his performance in season two of The Walking Dead. 
Norman Reedus' other film and television roles include playing a character named Jeremy in 1997's Mimic, a vampire familiar named Scud in 2002's Blade II and Josh Rollins in 2009's Messengers 2: The Scarecrow. His TV credits, outside of The Walking Dead, include two episodes of Charmed where he played a character named Nate Parks and the "Cigarette Burns" episode of Masters of Horror where he played a movie theater projectionist named Kirby Sweetman.
