So, after a few years on and off of work, I’ve finally figured out this whole xenoquine thing!
 
I’m currently working on a xenomorph/MLP crossover where Twilight, patient zero, found out a way to safely remove chestbursters. In addition, Xenomorphs take on not just the body of ponies, but also take in the magic of Friendship and ability to feel empathy. It’s… a whole thing. They’re called xenoquines, and I have half of a species sheet ready to go, that I’ll be uploading soon.
 
Here’s the protagonist of my fic-in-progress. Scratch, the first xenoquine.
