I have a feeling that this creature is going to do something special, and we may finally solve the mystery of how that facehugger in Alien smashed through Kanes helmet, to attach itself to his face (watching the footage it seemed that one of the characters helmets was
melting, with something moving around over the burn as he clutched his head (though it may just be his burning face).
Facehugger mark I, if it's something completely different and not related to the [proto] Xenomorphs whatsoever, I will be plessently surprised.
Edit:
By the look of it, there could be something else as well.
