Fan Casting Negan in HBO's The Walking Dead

He was the former leader of the Saviors. He used his authority and resources to subjugate other communities tribute to the Saviors, in exchange for protection against zombies. After Negan kills Glenn Rhee and takes control over Alexandria, the communities join together and start a conflict against the Saviors, ending with Negan's defeat and Dwight leading the Saviors, who begin to cooperate with the other communities. Negan is then incarcerated, receiving a life sentence. Two years later, Negan joins the Militia, having previously given advice to Rick during his time in prison. He subsequently proved his loyalty multiple times, primarily by saving Rick and Dwight, although this loyalty was met with heavy skepticism. After fighting in the Whisperer War and preventing a second conflict with the Saviors, Negan was allowed to walk free, but also exiled and forced to live alone at an outpost. He was eventually visited by Maggie Greene, who sought retribution for Glenn's death, but she ultimately spared Negan, deciding his new life of loneliness and depression was punishment enough. Several years after Rick Grimes' death, he continues to live as a hermit in an abandoned town, being visited sometimes by Carl Grimes. He also made a proper grave for Lucille, finally forgiving himself, acting as a changed and better man.
