Headcrabs are an alien race found in the Half-Life series of video games, originating in 1998's Half-Life. It is a creature that attacks people, trying to latch onto their face. Upon doing so, it begins to take control of their motor functions, turning them into zombie-like creatures that appear to retain their intelligence and emotions despite lacking the ability to express them in this state. The sequel, Half-Life 2, feature multiple new Headcrabs such as fast and poisonous ones, each creating different Headcrab Zombies.
