In the first episode of The Walking Dead: Dead City, the main villain, the Croat, is a former Savior, leading viewers to wonder if he ever appeared in the original series. However, Željko Ivanek's character did not appear in The Walking Dead and is a new addition to the franchise. The Croat was likely with the Saviors before they encountered Rick Grimes and his group, as he had a falling out with Negan long before the war against Alexandria. The character appears to have established himself as the ruler of Manhattan, using loud music to manipulate zombies and isolating his domain from the wider world. The Walking Dead: Dead City airs on Sundays on AMC.
