you know what the picture makes me think of the black pred? is that he might have another mask on his face!?
Lol, that's just a bad production photo, it looked pretty good in the movie I thought.
In regards to the differences between all the predators, yes they obviously have individual characteristics, but there are also obviously races within their species as well. We have seen several different predators that shared features with the original, some that had a similar appearance to Predator 2, & many at the end of AvP looked a lot alike.
The 'super' predators in the most recent film are most likely just another race with their own physical traits.
