The Walkers (The Walking Dead)
While human villains like the Governor and the Terminus cannibals come and go on The Walking Dead, the series will almost undoubtedly always have the threat of the undead adding surprise massacres to the characters’ daily lives. There aren’t thatmany people left on Earth, but there are still untold numbers of walkers roaming the woods and the streets, making it nearly impossible for the survivors to attain true comfort, even in a place as seemingly secure as Alexandria. The fact that the walkers have been responsible for the majority of deaths on The Walking Dead makes them a combined formidable opponent every step of the way.
