Alien (Thirst)

This Alien is a type of predatory creature, and main antagonist in the 2015 Sci-fi horror film; Thirst.

Description
The Alien in question has a centaur-like anatomy, standing taller than a Human. It possesses a set of human-like arms and hands, with two sets of legs and a long prehensile tail. While it does have a reptilian-like mouth with disarranged razor-sharp teeth, it also has a proboscis in its chest. Juveniles are also shown, resembling the adults but having a more human-like appearance, and patches of bioluminescent skin. The predators also don't seem to have eyes.

The alien shown in the film specifically has much of its body replaced with cyborg-esque machinery, with its tail, legs, hands, and area along the spinal cord having metallic attachments to the organic structure. It's uncertain whether it itself decided to replace its limbs or if another outside force physically made these changes, but given the juvenile's appearance without these metallic parts, it's not natural selection.

Reproduction
While not shown the exact method of reproduction, it has shown to bring back live prey items to its offspring to feed on, as their offspring are very vulnerable to the outside world.

Abilities
The Alien is shown to have both enhanced physical abilities. Its most notable one is its endurance level, shown to survive numerous amounts of physical trauma (from gunshots to crashing vehicles) without showing any signs of stress. It can run fast enough to keep pace with, and even outmaneuver, most Earth vehicles. Its tail is prehensile and able to move as easily as its hands, capable of piercing through prey.

Trivia

 * While it does have a reptilian like mouth, it's never shown to actually use it to attack. It mainly uses the proboscis in its chest to feed.
