Also if it were to have hoofed feet, why would it also not have paw like feet?
Do humans have four thumbs?
...no. What are you getting at with that? I was saying that the aliens have certain characteristics that no matter what the host will come through. Head shape, the tail, hand configuration (ya, I know they were different in all the movies except A:R and AvP, and Alien and A3. I prefer the Alien A3 design, but since if you count each conjoined finger as a single digit, each alien from each film has four fingers, so I say canonically they have four fingers to avoid that little plot-hole) behavior, etc.
The runner was diffferent, in part because of the host obviously, regardless of weather it was ox or dog. Im saying it could be because it was a different type aswell, from the queen facehugger in order to protect the queen and get things ready for it. It was faster than wat we've seen before, and moved differenty, but was the all-fours because of the ox or dog? The Aliens in other films also crawl on all fours, even hang upside down and move and get in positions (aside from crawling on celings and walls) that are unatural and impossible for humans. The Dragon was also seen on hind legs going bi-pedal from time to time aswell.
The human born aliens had dorsal spikes. Im going under the impression that they were for balance, for reasons disscussed in the thread concerning them. Nothing in humans would justify those, so its something that the alien was going to have regardless of host. The runner didn't, because being on all four primarily, it didn't need them. I adressed however that it may not have been the host that made it go on all fours. The Human born aliens were very apt at moving on all fours, so if an alien came out that way because thats how the host moved, doesnt seem nesissary. So perhaps it was because this special type of alien to clear the way for the queen, gather host, and protect the queens host, was this way because it needed to move faster to be able to effectivly do all this by itself.
