It just occurred to me "Serpent Hunter" might actually already be in lore, this is a pretty cool connection I think I made. So does everyone remember that comic from alien vs predator annual "chained to life and death"? In it they talk about a hunter who has more cumulative xeno kills than anyone else, but he's going on his last hunt because he's so old his body is failing. We know from the good folks at Neca that the Serpent Hunter is one of the oldest predators so this lines up well. Here's some stuff though that makes me really think it could be serpent!
First of all just like the serpent bio it says he tries to think like them:
But also it says he's the Very best, that none had killed more xenos none had collected as many skulls
IDK guys, sorry if the images aren't working but I think he might be the same guy, same secluded attitude, same characteristics, and same track record of being the very best xeno hunter ever. Maybe this was on purpose as an homage or maybe I spend way too much time reading these comics.
