Alien Roar

So this is the alien from the alien and AvP movies. Er. Sort of. He's kinda different from any of the existing ones. Way too big to be a normal one and not quite big enough to be a queen, so I'm saying he's a king. He can stand in a bipedal position as well, and then in his most comfortable position, he is around 1 foot 8 inches, though he can extend his legs further to be around 2 feet or more. Obviously, he can open and close his mouth, but he also has a retractable inner mouth on a gear system that can open and close as well. For more detail on the head, go here: [link]
