The alien was a robot created by James Finson for Untitled Alien Ripoff in End of Take. The film was to be shot at the Factory. X.A.N.A. possessed the robot. The alien trapped various people, including Sissi and Ulrich, with goo that shot out of its mouth, before being stopped.The alien was quite agile and athletic, and its claws could rip through metal. It could also spit a disgusting goo out its mouth which trapped its opposition in a sticky unescapable webbing. It also licked Sissi's face, in a depraved act. Finson based it off the Xenomorph from the Alien Franchise, as pointed out by Ulrich.
