Interesting, why does alien wariors have tnis long pies on their backs? Runers dont have them and queeny have long spikes ____________________________________________ _ Queens, Warriors & Runners are all different therefore the tubes wont be identical or they wont have them at all. The dog-alien or runner didn't have them because they couldn't fit them on because of the size of the dog-alien being smaller. but from a film point of view it may be because the alien inherits some charachteristic's and not other one's, i mean if every alien looked the same from different host's that would be boring. Hope that kinda explains tings?
