The Fate of the Deacon

There is probably only one Deacon. It originated from "black goo" infecting Holloway, who then infected Shaw, who gave "birth" to the octopus who then infected the Engineer, and there is where the Deacon appeared. These species incorporate DNA and genetic aspects of their hosts. So since we see black goo (bioweapon?) mix with two humans and one engineer, the Deacon is unique. Doubtful any on Paradise or anywhere else for that matter.

For all we know humans could or could've been on paradise for experiments or reasons unknown.

first child what do you mean as in it became the mountain. That is a hell of a size. What is it's appearance ?

In paradise Ridleys going for a total different  look so we could yet see the deacon or even a few, or maybe even it's offspring. 

whatever happens I can't wait!

It's gonna be proper weird going to cinema to watch paradise. Unreal#

@DenzelTH, Ridley has said in recent interviews that there will be no more "dragons" or "snarling beasts" in his upcoming sequel. He's going in a different kind of direction than the monster flick that so many seem to be hoping for.

The graphic novels are of course a different thing, and anything seems to be open for that.

I stay away from those because of the unfortunate Predator tie-in.  

To answer you question DenzeITH, the Deacon came into contact with more black goo and grew to be a giant creature that lives underneath a mountain. You can even say he is the mountain since it is basicly it covered with dirt and rocks. While growing, Vickers escape pod feused with it. The creature now has the suite inside of its body, acting almost like a tumor. You never get to see the creatures appearance in the comics, but this is known:

It has acid for blood

It has some giger styled internal organs.

The xenomorphs fear it. (They will literally not even go near the thing throughout the series).

It willing feuses with a android alien hybrid and seems to be in a strange way (friendly).

It is intelligent. It can communicate to Elden, the android, once he is feused with it.
