When I was designing this guy I was aiming for him to fit on the planet of Darwin IV from Wayne Barlowe's Expedition, and Alien Planet

It’s a predator that naturally lives in the mountainous regions of Darwin IV. It’s an ambush predator, sneaking up on its prey, and jumping on top of them from above. It stabs its prey with its three outward protruding horns on its head, filling it with digestive enzymes, and then the prey is sucked dry using the appendage that comes out of its chest.
