Alien face hugger...

The Alien movies have a few different types of aliens in them, apart from the most well know one there are ones referred to as face huggers. This aliens purpose is to inject embryos(eggs) into a human to keep the cycle going! They do this by almost hugging a persons face wrapping it legs around the head and tail around the individuals neck and begins planting the eggs down the throat, it then detaches and crawls away and dies. This leaves the person in a seriously bad way because they have a alien growing in there stomach which has to literally explodes for the alien to come out of the stomach.
