Chestburster

The chestburster, is the fetal form of the xenomorph and the third stage in its life cycle. It is most well known for its horrific method of gestation – it is implanted into a host lifeform's chest cavity by a facehugger, and upon maturing it will erupt violently from the host's chest, killing them in an incredibly bloody and traumatic fashion. It is like a large worms, beige or brown in color and with a mouth of sharp teeth and a tail capable of propelling the creature at considerable speed.
