There have been different portrayals of aliens in the movies and television shows. For the most part, aliens look similar to humans because they have limbs like two arms and two legs. They would also have some kind of eyes, nose and mouth, but they may look different than they do on humans.
However, their skin would be different because it would be scaly. Their bodies are just as fragile and get injured like human beings. The aliens almost look half human, but half animalistic. They would be multiple colors or I picture them as having a gray color like ET was. It is hard to determine what aliens will look like, but I have several pictures of aliens in my head, not just one.
