Xenomorph

Flamethrowers, electric prods, nets, and open airlocks can't keep the Xenomorph from getting up-close and personal with any available host – human or otherwise. But don't let its huge mouth scare you - it's the smaller mouth inside that's hungry for prey. With a protective exoskeleton, flexible tail, and corrosive blood, the Xenomorph’s always ready for battle. © 20th Century Studios
