The explanations I got is in short:
Such as effect flora and fauna.
"What we see in Alien Covenant's that it only targets fauna, not flora.
The films always take precedence yes?
but all the information you need's in Covenant, you just have to be able to recognise things for what they are."
seen prometheus maybe 15 times and covenant 20 times but its not explaining clearly the rules the black goo work and even contradicts itself.
I do listen to your info and not ignoring it but its not explaining it in detail and setting up clear rules for how the black goo work. like these examples why it in certain cases mutates a creature, and in the next scenario kills instead of mutating it, (and in the next make hybrids? not canon so can skip this one but in my head it exist)
Or when it creates these spore pods/mushrroms, is it related to time, temperature, like what exactly needs to happen for it to create such things?
My best theory is david somehow made experiments on the creatures and one resulted in those mushroom spore pods, spore pods as some call them. But the movie dont tell what made them to exist and what needs to happen to make them happen natrually?
and like prometheus shown: the creatures the black goo get in contact with and mutates has acid blood, and in covenant it lacks that and kills directly instead. Neomorphs had normal blood, no acid blood.
The movies didnt explain it completely and leaving it vauge for guessing, myself want full explanation and clear rule like: black goo get in contact with a creature it will mutate it by: x amount of black goo, and y amount of hours will result in this: x. If the finished creature get in contact with black goo again: nothing will happen.
OR: black goo when in contact with plants will mutate them into spore carrying pods after ca 1 day. (a s example, it didnt do it in covenant but its an example., clear rules like how the xeno work or basicly anything).
