What's the mutagenic substance introduced by the Trilobite to create a Deacon?

[Immortan Jonesy]

According to the gospel a facehugger produces a mutagenic substance called plagiarus praepotens (plagiarus linesteres in the case of praetomorphs) in order to create a chestburster within a host.

Does the same thing happen with the deacon, whose life cycle is very similar to that of the Alien? I mean the trilobite introducing a mutagenic substance into the Engineer to create the creature.

Good question, I can't say for certain but I imagine it's similar to the process of incubation the Neomorph experiences, judging by the way they both use their pointed parts as applicable to get out of the host.

In universe must be a similar mutagen for Deacon and Neomorph.

Yes.

It's interesting because for the Neomorph although the Pods act like Eggs, the Motes act as the Facehugger, they actually disappear into the host (although they may also die inside after serving their function) as depositing the mutagen.

In this way the Trilobite's closer to a Facehugger functionally using a human being's ovum with sperm as the Egg.

But it makes me wonder if Plagiarus Preapotens, and the Plagiarus Linesteres, exist basically as forms of The Pathogen itself programmed to perform a specific purpose.

Meaning that the Motes probably deposit "Plagiarus X" let's say.

And that the Trilobites probably deposit "Plagiarus O" for example.

In the way this applies to the main Alien species with the three types of Egg and Facehugger we now know of.
