Avp 2004 the last great Alien and Predator film.

David used the pathogen and some insects to create the Alien. What's to figure out?

He did in Covenant but is that what created The Deacon in Prometheus?

The Pathogen by default creates Neomorphs, David used it to create/recreate the Alien.
Questions about the Pathogen?

Spoiler

David sacrifices the Engineers against their will- wiping the planet clean and bringing forth Neomorphs.
And the Neomorph has every feature the Deacon has, except it also has back spines and a tail.
Generally in appearance is closer to Carlos Huante's concept art.

Deployment of Pathogen on a planet:

Spore Pod = Egg
Notes = Facehugger
Bloodburster = Chestburster
Neomorph = Xenomorph

I believe that in a planet wide infection, Deacons do get created-
Perhaps it even bypasses the Trilobite if the reproductive system is functional.
But it still requires indirect contact- drinking from a river that became infected for instance-
Then if sex occurred, we know the rest- the woman likely dies in birth and the man turns into a raving lunatic and is going to explode.
If it creates a Trilobite the Trilobite needs to survive until it's fully grown and then infect someone else.
If it goes straight to Deacon, which it may well do- sure.

Unlike the Neomorph being generated though- this requires two people to have sex; 
Which is far, far more unlikely than some poor sod being in the initial blast radius or
looking for food in the wilderness and getting infected by spores.

This all said;
I actually believe the Deacon of Prometheus is one of a kind, and owes its skin colour to the fact it was
generated through two distinctly different beings, the Engineer and a pair of humans.
Considering literally everything else that was generated solely from one species
in the prequel films is pale white and partially translucent.

The Pathogen always creates a creature slightly different yes, but the chaos is consistent- for example;

"The original liquid atomized to particles when exposed to the air."

"The pathogen was designed to affect all non-botanical life forms.
All the animals, the 'meat', if you will... either kill them outright
or use them as incubators to spawn a hybrid form, highly aggressive."

"From the eggs, came these parasites... shock troops
of the genetic assault.Waiting for a host, entering the host...
rewriting the DNA... and ultimately... producing,
these enviable unions."

Apply deductive reasoning and you start to discover patterns in all things it creates;

The Neomorphs and LV-223 creations all have:
-Acidic blood/saliva
-Pale, translucent skin
-Elongated limbs
-Extra appendages; back spines, extra fingers and a pharyngeal jaw in the Neomorphs' case.
(The unfolding appendages around the head hiding an attack method
in the case of the Hammerpedes and Trilobite, much like the pharyngeal jaw.)

Where-as I'd say the infected personnel of those on LV-223 all shared similar qualities.
The infected Sean Fifield is quite obvious, he became bloated in the cranium, with veins rising to the surface.
In behaviour became extremely aggressive and violent. It's unclear if his proportions were effected.

The infected Charlie Holloway carries many of the same traits, with veins rising to the surface of his skin
and becoming aggressive when crew members of the Prometheus tried to assist him.
I hypothesize it likely that he would have became what the "Fifield Monster" was if given time.

A prolonged death sentence.

Why death? No incubation?
Essentially because it's been stated by the production that Holloway and Fifield
were on the same path that the decapitated Engineer was on.
They showed many of the same symptoms as the infected Engineer, so I supposition that with this usage of the Pathogen;
That if infected it will; (depending upon dosage) increasingly send the victim into a violent rage,
increasing their physical attributes while returning the mental ones to that of the entirely primal;
until their cranium explodes and they finally die. Potential incubation unknown. Alien The RPG essentially confirmed as much.

Clearly not.

Thanks The Great Old One and SM for the info on David's work. I've fallen behind on alot of this stuff so that helps clear things up. To mention AVP 2004 again I would say that I think Predators is better than AVP even though I like AVP alot. Up until The Predator I would have said that as its own franchise that Predator didn't have any out right bad entries but 2018 happened.

[happypred]

I can understand the position that AvP is better than Requiem... but I can't see how AvP is "great"

[The Old One]

Yeah, agreed.

If only you were a movie  another bird would sing!!! *I'm not crying, you're crying*

Indeed, and the OG AVP story.
