i was watching a video on YouTube the other day and noticed something , barring avp/r, alien3, and resurrection as those creature either didnt come from human hosts, were the result of tampering with the xenos to make them better to hunt(cunning of the dome heads, grow faster, predictable queen based breeding),had human dna mixed in, or the result of "direct injection" from a grown alien; there are different xenos from different facehuggers. the facehugger in alien looked like this
and resulted in an 8 foot creature with 6 fingers, a domed head, human like intelligence and reproduced through eggmorphing(supposedly) creature
in aliens the facehuggers looked like this
which resulted in the 5.5-6.5 foot, 3 fingered, ridge-headed, amimal intellegence , queen based reproduction creature
also in aliens Russ Jordan accessed the ship and egg chanber through a crack in the hull as opposed to entering like the mostromo crew did.
kind of find this interesting that this wasn't in the weylan yutani report because it does look like there are 2 different 'races' of xenos
white i understand this may be a result of better animatronics, the only time you see the 'proper Gieger alien' in film canon is after a host is infected with the facehugger in the first picture or am i reading too much into this?
