excuse me. but if you haven't noticed. i hate the comics and books. and as for the roaring sounds - again, the aliens do take air into their bodies but it is not the main source of fuel, it is broken down into compound chemicals and fed into the bloodstream, their circulatory system is nothing compared to ours, its scientifically know as an 'open circulatory system' simular to that of a fish etc, the alien has no lungs. a being which relies on oxygen to breath CANNOT survive in space. these are studied theories taken from various sources, i get research on facts form all over the net and official books on the creatures and collaberate data to find out what the general opinions are and then formulate my own from them. these are not from the pathetic comics or books which break the boundaries of what i find to be plausable. ganted your response on the alien being able to make noise is a factor as without air there is no sound, buttttt - again, the alien can survive in any environment, with air, without air, underwater, and as been stated from so many sources i've taken time to read, the aliens dont posses lungs or 'need' oxygen to survive.
