The science fiction creature that I would least like to run up against is definitely the xenomorph from Alien. Something bursting out of your chest is bad enough, but the thought of the facehugger grabbing your head and cramming eggs into your stomach is not good. Alien fans will soon be able to get their hands on a life-size facehugger of their own.
The replica will come from NECA sometime this summer. The creepy crawler is made of foam and will have a bendable tail, and is guaranteed to give you nightmares.
Other details on the replica are unknown at this point. Specifically we don’t know how its exact dimensions, and we have no idea how much it will cost. You can count on it not being cheap though; cool sci-fi replicas like these are never cheap.
