Xenomorph Life Cycle

what does the xeno do to make a human morph into an egg though? perhaps its blood?

Yeah that's right. If you notice, the alien that came out of the bull has a quadrupedal stance 

Shasta: We have carnivorous plants that trap insects, dissolve them with some strong chemical and take up the nutrients. We know that the xenomorph can produce acid. The rest of the transformation is in the genetical makeup, I suppose?

You're, right Alien426.

it would suggest that the black goo and the xeno r def connected in some way. ridleys intention was to show the xeno morphed kane and dallas into eggs which would support this connection as the goo mutates what it infects. due to this I would think the xeno wouldnt morph into anything as possibly the black goo has the same base dna/ cell structure as the xeno???

If you fed the Xeno the Black Goo.... then you would end up with a Xeno-Hybrid that would be 50% Xeno and 50% what ever Xeno related Organism is contained in the Black Goo

If you mean Sacrificial Goo.. then maybe this is what the result was in those Urns... or at least off a related Ancestor or Evolutionary Predecessor

As far as the Life Cycle..

Alien showed us in full cut (as with Star Beast) the Adult can Mutate the Genetic Material of a Host to become a Egg (Egg Morph) but these Eggs are larger.. so its interesting to see do they shrink?  or do they produce larger Organism.

Cameron ignored that and gave us the Queen.. which opens up the Chicken or Egg Debate..

I always felt the way to Merge both ideas.. was the Egg Morph would Produce a Queen or a Queen Face Hugger.

But i think the true Origin when revealed would be different to both Alien and Aliens...

I think maybe even the queen makes eggs by injecting black goo into the organic biomass she creates.  The drones or warriors just can't produce the biomass from eggsac, so they use what's around. 

And yes, the egg might shrink.

I would rather make the egg morph leads to queen. So if a queen dies and leaves eggs...alien rise...egg morph a subject to become the new queen..bigger egg queen facehugger...and bam..

However queen is huge.alien 3 show us she borns of ripley..if they make it a dream...like a4...then we can assume it isnt totally canon..wich would be the best route.

Rewrite the queen life cycle...or a chosen alien warrior eggmorphing itself to queen status...i prefer the first mentioned.bringing back the eggmorph concept as the only way for common aliens to rise a queen that leads the hive and produces eggs to build the xeno hierarchy and population.

Erasing the alien impregnation we had on a4:-).since its a dream while ripley is in cryosleep woudnt be accurate aswell.

"The Life cycle seems to involve a living host (e.g. a human) which slowly disintegrates and changes into an egg (in which a face hugger will develope)."

Living or dead hosts can be changed into eggs.

"The Face hugger seeks a new host and plants an embryo in the stomach (through a tube inserted in the victim's throat)."

It gestates in the chest; not the stomach.

S.M: Yes, I have thought about that too. This is fiction, but if we want to try to make sense (scientifically) of it, the alien embryo is inserted in the host through a tube that goes either into the windpipe or the food pipe. If the alien grows in the lower part of the windpipe or in a lung, the host would probably suffocate. If, it grows in the upper part of the stomach, however, it would be fed and the host would eat a lot (which Kane does).

@ chli

That makes sense.

wonder what happens to the xeno after it dies? with its exoskeleton and acid blood? it dissolves itself leaving no foot print?

Indeed how does that Chestburster embryo make its way through the esophagus? I knew it developed in the chest cavity behind the ribs but logically speaking, how would it get there? Most invasive parasites / worms we come in contact with are incapable of moving through membrane and tissue that way and generally stick to the walls of whatever organ they entered through. Although some, small enough I'm sure could make their way through. 

@Big Dave, imagine Black Goo infecting a Xenomorph?! Assuming of course the Xenomorph is not immune to its effects of course.

i wrote a poem about the life cycle somewhere else....here i'll show you!
a child is born.....to hug a face. a child is born to make an egg. a child is born to hug...another face! a queen is born to end a race........and when the race is laid to waste...the queen and her soldiers..they die with haste!
you see now!? it all comes together! your eyes are open! and you're welcome!

Never doubted your romantic twisted vision id.

You a peculiar one xD

"@Big Dave, imagine Black Goo infecting a Xenomorph?! Assuming of course the Xenomorph is not immune to its effects of course."

This is a interesting thing to bring up, we simply dont know... i would assume the Sacrificial Goo could break down a Xeno.

But the stuff in the Urns is open for debate.. i suppose it depends if the Genetic Code or Program within the Urns is different to the infected Organism.

Because it appears the  Hammepedes are evolved by the Black Goo and once they have been evolved so are a Hybrid of Black Goo Mutagen and Worm DNA.... they appear to swim in the Black Goo without being transformed any more.

We latter see the Hammerpede again (Milburn Mouth Burster Scene) and it has not changed.

So its hard to say really what happens if a Xeno is introduced to the Black Goo. I guess it depends what amount of Black Goo DNA the Xeno already has and what process and connection they have i.e which predates which.

@Shasta Cyclone "the aliens blood oxidizes after death completely neutralizing it" Bishop, Aliens

I'm of the strong belief that the black goo is a retro viral agent with possible nanite enhancement that was based on a substance that the Xenos produce to propagate, egg morph, and take on genetic characteristics of their host. 

The LV-223 engineers botched their recipe.

I'd happily accept that idea if it is presented in the films. It would maintain the mystique of the xeno whereas having their origin set as an intentionally manufactured weapon would detract from it.

I do find the idea that the engineers or (dare I say) David created them in a lab intentionally is interesting, but that will inevitably take the xenos down a few notches.

Ultimately there are only two theories I'd say would be a win-win for me personally.

The first is what you've already proposed. That the xeno origin remains a mystery, the engineers simply got a hold of their DNA and attempted to replicate them.
(I should mention that for this concept to work, we would have to accept that we may have never seen a real xeno in any of the films with exception to the AVP movies. It would depend on whether the derelict cargo is framed as collected or manufactured specimens)

The other concept I'd be equally satisfied with is the idea that the engineers accidentally created xenos billions of years ago when attempting to achieve some unrelated breakthrough (such as reproductive restoration or something similar.)
I find the accidental element critical (IMO) for the xenos to maintain their mystique (if the manufactured route is taken.) This would also perhaps be the scenario that would better fit with theories of factions. In such a scenario, perhaps once the engineers stumbled onto this accidental DNA cocktail, one faction would see opportunity to conquer the universe with the ultimate weapon while another would feel it was an abomination that should not exist.

Either way I'm hopeful that the xenos won't be robbed of their mystery.

QES

I have often thought that ur second concept there is true. for example. I believe the goo is the weapon and designed to wipe out organic life, not mutate it. the fact that shaw is impregnated by an infected Holloway surely couldn't have been in the engineers calculations when making the stuff could it? so then the trilobite is a fluke hence the deacon is a fluke. but this process has already happened thousands of years ago perhaps. so they infact, unintentionally, end up with 2 bio weapons?? or they believe the creature created by accident is some for of sign or next stage of evolution??

i buy qes takes.

I also buy the take of the origin of xeno being a more primitive anscient beast with unique biology and bacteria traits.

So like finding a dog and turning it into a wolf, or a lion through technologic exprimentations engineers made.

So like we take venom from snakes to make remedys for diseases they take blood from this species or something and make goo and all other stuff, but their biology is so unique at a celular level that is constantly evolving when it finds a host. Kinda like venom symbiosis in spiderman comics..so no matter how they reverse it the bacterial traits allways find a way to evolve and take over lifeforms to dominate.

Then perfect organism could be tackled this way...the original beast was weaponised.

But i wil have a more cohesive theory when i see ac and see if those eggs were there or were created by david..and see how diferent is this so called protomorph..is he the origin..the anscient primitive specie thats gonna be weaponised by david? Or is he the weaponisee version already but still not refined..

This is the answer im looking foward

About the black goo’s effect at a Xeno, I guess it depends if we consider the Xeno as the ultimate version of what the go is supposed to create or not. Suppose that the Xeno is just a result of evolution like humans are to apes then the goo being used at a Xeno would create something else. This is my guess but maybe someone else has a better explanation.

when a xeno eats black goo......it turns into a human!
