Okay, so I’ve been wondering about running an adventure featuring Xenomorphs (from the Alien franchise) for a few years (like, before 5e was even a rumor), and with the release of Prometheus and Alien: Covenant and the thread about the Expedition to the Barrier Peaks on Athas by @ProfessorZik-Chil, my interest in doing so has been reignited.
Now, what if Xenomorphs came to Athas via a crashed ship (Engineers?) or have always existed trapped in some underground corner of Athas for untold ages (probably just eggs since they would all die out)?
Considering Athas is already extremely hostile i think they would fit right in. Also we would get some pretty freaky hybrids (B’rohg Xenomorphs anyone?)
So i wanted to ask the community, if you were to do this:
¤ How would you have them arrive/appear?
¤ What would their effect be upon Athas, how quickly would they overrun it, if they even could? Taking all the powers (SM’s, Dragon, etc.) into account.
¤ What adventure ideas/hooks can you think of?
¤ Would you use the Neomorphs as the originals and then some SM tries to mutate and harness them as weapons, therefore creating the original Xenomorphs we know?
¤ What CR would you make them?
Here are some 5e Stats i found for them:
And the Neomorph:
