or they could go with a human predator similar to the ripley alien combination that was in alien: resurection. That could be interesting.
Predators don't take on the attributes of their hosts like the xenomorphs do. That's why there are so many different types of alien, and only one type (a definitive species) of Predator.
Namely:
Alien = Walked upright, was the result of a human host. Tried to create a Queen by turning the Nostromo into a nest, and failed.
Aliens = Walked upright again, but was more advanced due to the time the xenos were allowed to live before the Marines arrived. Queen was able to come about since the reactor was turned into a nest.
Alien3 = was born of a dog; looked like a dog, moved like a dog. (In the special edition, you get to actually see the Queen Facehugger that was attached to Ripley, and xenomorph was actually born of a dead cow....go figure that one.)
Resurrection = Queen born of a cloned Ripley, was hybridized so she gained the human reproductive system (had "sex" with the lead scientist): gave birth to a human/alien hybrid, not an alien with human traits. Other aliens were from human hosts, so they acted like those from the previous films.
AvP = Aliens from human hosts, so they acted like other aliens previously. At the end of the film, a xenomorph born of a Predator = Predalien, an alien with Predator attributes (mandibles and dreadlocks).
It'd just be jacked up if *any* Predator had relations with humans, historically their prey. I even found it reaching that the Predator teamed with a human in AvP1, but accepted it since the human was the one who killed the xenomorph, gaining the Predator's respect. My only wish from the AvP film, though? I wish that the lead woman's name was Ripley :3
