Facehugger

The Facehugger is a parasitic creature that hatches from an Ovomorph and is the second stage in the Xenomorph's life cycle. It measures 150 cm in length, 45 cm in width, and weighs 4.5kg. The creature has a beige skin color and greatly resembles a pair of skeletal hands fused together, with a spine-like tail. Its eight long, finger-like legs allow it to crawl rapidly, and a long tail adapted for making great leaps. These particular appendages give it an appearance somewhat comparable to Chelicerate arthropods such as arachnids and horseshoe crabs.

The Facehugger's long digits allow it to move rapidly across all manner of surfaces and also grant the creature its crucial ability to "grip" a host's head, hips or waist during impregnation. They are incredibly strong, and have been known to tear the skin from the skulls of human victims when an attempt is made to remove them. Once the digits are gripped around a host's head, hip or waist, they are nigh impossible to remove and implantation is virtually guaranteed. A Facehugger's tail can propel the creature into huge leaps and is also used for additional grip around a host's neck, waist, thigh or whatever, during impregnation.

Situated on either side of the creature's body at the base of the tail are a pair of bag-like bladder (balls) structures that are used to store sperm and circulate air into the victim's lungs during impregnation. Underneath the Facehugger is a small orifice, from which the creature will extend a dick-shaped proboscis used for delivering sperm; this proboscis is around 20 to 60 centimeters in length. While fragile and ill-equipped for combat, Facehuggers' small size and rapid movement makes them adept at ambushing potential hosts, and also makes them difficult to kill.

When a Facehugger initially senses a nearby host, it will attempt to attach to and subdue them. Once in range, the Facehugger will leap towards the host, often with alarming force and accuracy, and immediately wrap its tail around their neck and its digits around their skull or wrap its tail around their thigh and its digits around their hips. While the primary method of subduing the host is chemical, Facehuggers can also use their tail, wrapped around the victim's throat, to induce asphyxiation.

Once securely in place, the Facehugger inserts its dick-shaped proboscis down the victim's pussy, mouth or ass. It will thrust its proboscis until it's fully inside the victim's channel. This proboscis is used to impregnate by letting out their sperm or deposit its eggs inside the victim. They will then start to deposit an oily lubricant and nutritive liquid as well as eggs, which bulge out the victim's throat as they're forced to swallow them down or will bulge their belly. Facehuggers will preferentially attach themselves to pussies or anuses, but may attach themselves to faces if they cannot get to the other two holes. Despite not being very intelligent, facehuggers have distinct personalities, where some are more gentle and others more aggressive.
