I have a THEORY for Predator Badlands:
What if this isn’t the Predator, and isn’t Elle Fanning’s character, but it’s Royce?
Adrien Brody is listed as the only other member of the cast alongside Elle Fanning, and this would explain why the masked individual in the picture has a smaller frame that you wouldn’t expect a Predator to have, but still appears to be wearing some kind of Predator Biomask or something similar to it. We have also never seen a Predator wearing any kind of hood as far as I’m aware of in the lore.
Last we heard of Royce, he was commandeering a Predator spacecraft to try & find the Predator homeworld (Yautja Prime), according to Isabelle Nissenaum in Predator Hunting Grounds. We also know Royce had access to more Predator gear & equipment than just a ship because of the sequel comic to Predators 2010. Predator Badlands is also the only other movie in the franchise set to take place on an alien planet, just like Predators 2010.
This could just be an error of some kind, but if Royce were to appear in the movie, this could make a lot of sense.
