Headcrab

The headcrab is a terrifying alien parasite that has been wreaking havoc on the planet since its arrival in 1998. These creatures are known for their ability to attach themselves to the heads of their victims, taking control of their bodies and using them as hosts. Headcrabs are incredibly strong and resilient, and they can withstand a lot of damage. They are also extremely fast, making them difficult to escape from. If you are unlucky enough to be attacked by a headcrab, your only hope is to kill it quickly before it can take control of you. But even if you do manage to kill a headcrab, there's no guarantee that you're safe. These creatures lay eggs, and if one of those eggs hatches, you'll have a whole new headcrab to deal with. The headcrab is a truly terrifying creature, and it's one that you definitely don't want to mess with. If you ever see one, your best bet is to run away as fast as you can.
