A "zombie" is a fictional undead creature often depicted in horror and fantasy genres. Typically, zombies are portrayed as reanimated corpses that have lost their human consciousness and are driven by a primal urge to feed on the living. They are commonly associated with apocalyptic scenarios and are popular in movies, video games, and literature. The concept of zombies has roots in various cultures, but the modern interpretation largely stems from the 1968 film Night of the Living Dead by George A. Romero. This film established many conventions of the zombie genre, including the idea of a viral outbreak that turns people into zombies, influencing countless works in popular culture.
