Alien (Signs)

This article is about the sapient alien race featured in the movie signs, directed by M. Night Shyamalan. They are very athletic, being able to jump up to the roof of a farmhouse that is about ten feet off the ground. Their skin changes colors, giving them a camouflage ability- which is how they remain unseen throughout most of the movie. They also have a spike that protrudes from their wrists that expels poisonous gas. Water is their weakness- shown at the end of the movie when the one in the farmhouse falls backwards into a piece of furniture, toppling a glass of water on top of it, causing the water to drip on it. The water seems to "burn" the alien and cause it great amounts of pain.

Technology
This species has clearly established their ability to master space travel in order to get to Earth. Their ships can primarily be seen at night via the yellow-orange lights that show that they are in fact saucer shaped craft. Graham Hess asked his brother Merrill if there had been any new development and Merrill explained that a bird flew in the way and hit something in the sky and fell straight down; explaining that they did in fact master cloaking technology. It is also unknown what kind of weapons these creatures possess due to the fact that they did not use them within the film.

Despite their advantages over human technology; there are several pieces of technology that they are not familiar with such as doors; which they seem to have trouble getting through. They also have trouble getting through wood as well.
