Headcrab

Intro Headcrabs are malevolent extraterrestrial parasites in the Half-Life video game series. They serve as the iconic and central antagonists, able to leap onto the heads of unsuspecting hosts, taking over their minds and bodies. Headcrabs are small, crab-like creatures with razor-sharp claws, a glistening shell, and an intense, predatory instinct. Their connection with victims is both physical and metaphysical, linking the parasite's neurological system with the host's brain, essentially transforming them into zombies. They possess a silent and stealthy demeanor until they attach to a host, at which point the transformation process is both violent and disturbing. They are devoid of mercy or compassion, driven solely by an insatiable hunger for more hosts. Headcrabs have no known friends or allies and are in constant conflict with the game's protagonists, who are usually scientists or security personnel.
