It feels that the Neomorph is way more of a “perfect organism” than the xenomorph. First off, the life cycle is more efficient. Nothing is quicker than spreading disease than an airborne pathogen. It seems that if anything, an Egg and a face-hugger just complicate things. Also, after the neomorph is born it is instantly dangerous because it’s just a smaller version of the adult. The xenomorph on the other hand(in all other movies besides AC) have an infantile stage which is the chesterbuster we all know and love. The only time a chest buster killed anyone other than the host was in Alien Resurrection. Larry purvis chestbuster kills Dr. Mason Wren. What are your thoughts?
Spores are ofcourse more efficient & undetectable method of impregnation. And I see no difference between Neo & Xeno in terms of strength & agility. So what David did, simply didn't result into anything special.
The only advantage I see is that the Facehuggers are more locomotion-oriented and can crawl and hunt the host more specifically instead of air-borne spores which is much dependant on the force of the wind.
>> Facehuggers can move long distance and specifically. Rooms to Rooms, Wall to Walls.
>> Facehuggers can attack the host even in his suit and helmets. It has the ability to slowly erode glasses of Helmets & Hypersleep chambers and make its way through without harming the host.
>> Facehuggers can temporarily put the host unconscious (and incur temporary amnesia). This can prevent the host attempting to kill himself/herself after he/she learns that they're infected and hence preventing the death of undeveloped chestbuster embryo.
>> I think Facehuggers also bear some intelligence allowing them to specifically attack at the right moment, Run, Hide etc. Just my guess. As we see in Aliens, the facehuggers attacked Ripley & Newt just when they went to sleep and in a room where there weren't soldiers around. I wouldn't say literally that intelligent but in some way, they act more voluntarily.
If at all David improvised the Alien lifecylce, he did it by introducing (engineering) Facehugger.
At the end, we also see that the Facehuggers eggs are even more handy & transportable if they're in its embryo form.
>> About Spores, I think that the Pods needed to stay on ground. They're most probably mutated spore-producing Fungus. Its grown on Tree stems/roots. So it needs to remain attached. If its true, then ofcourse, they aren't transportatable or else one need to cut the whole tree stem alongwith it. Just my guess.
