Greetings movie goers So which creatures in science fiction films were the most memorable in your opinion? The Hybrid from AVP 2 is the most memorable to me. Take all that is cool about an Alien and cross it with a Predator and you got one kick ass Alien that you can never forget. Then I would have to say The Borg From Star Trek First contact. So how about you, What is the most memorable SciFi alien in your opinion.
