Zombies (Night of the Living Dead)

Zombies are the titular main antagonists of George A. Romero's Night of the Living Dead along with its various sequels and remakes, unlike the zombies found in movies such as 28 Days Later or videogames such as Resident Evil, the zombies of Night of the Living Dead are traditionally slow-moving monsters known as the "walking dead". Later remakes and reboots feature zombies moving fast and even evolving in terms of intelligence.
