As long as you're in this topic, you're more than welcome to request a fight. As for being a Predalien in RPGs, you just need to say your character is a Predalien, and that's it.
Xenotor, you need at least thirty points to be a predalien because of the new system, until then, you must settle for being something else (A warrior, drone, facehugger or chestburster).
You guys have a storyline already because i have a idea how about one of the predators gets a facehugger attached to it than a predalien is born i am a chestburster so i will play as it.
