Hmmm. yes, I have some. Mainly some alien sience, junno how a alien would look like when its inside on of those things.(thats in the xenopedia)
Aliens book one (comic from darkhorse, its a direct sequal to aliens before alien3 got released....Hicks is alive in this comic and Newt too. He, Newt and Ripley are on earth and it takes place a few years after the second movie) has a plot twist were one of those creatures appears and explains what his race was and how the alien wiped out his race. They are explorers, like giant trekkies. lol. They gather info on spiecies etc. In book one he saves they day and explains to Newt (telepathicly) who they are. I got the comic in pdf somewere, I can send you it if you like.
I dont see the comics as a reference though. The movies are leading in the franchise. And since the movies explains little about the space jockey, its all speculation. In the xenopedia theres a few things....but its too much trouble to type lol.
Xenopedia 2 covers the 3 comics of the first 3 movies. And a reather interessting one of the second movie were the first pages cover everything from Newts point of few. You see how the Colony is infested and how the colonists fight the first alien horde.
