Andrew Lincoln's Rick Grimes has been the group leader on AMC's "The Walking Dead" since season 1, but there are other survivors that could do a great job at it. Description from fireworksimages.net. I searched for this on bing.com/images
Rick Grimes is a small-town sheriff's deputy who is wounded in the line of duty and wakes to a zombie apocalypse. Alone, he sets off in search of his wife, Lori, and young son, Carl. Rick is an everyman — smart, calm, just, a good friend and father — but will often stubbornly cling to his personal strong moral code. "We don't kill the living," he tells Daryl at gunpoint when the latter attempts to kill an infected survivor.
