I wonder if Tim Lebbon may be curious to check out Perry's works. Because the irony is that his Predators do have a bit of Perry influences in them as well as some slight Hish despite Mr. Lebbon having not read either of these works.
Like I mentioned, the Yautja have genders, they behave under some kind of rules but tend to be much more individual and independent which leaves room for certain individuals exhibiting Hish like behaviour.
For instance, Shamana was a very chill Yautja, telling Wendigo to remain calm, meanwhile Wendigo went all berserker on the humans despite Shamana telling her to leave them alone. It's like Wendigo's fury gland got activated or something.
But in the end, I'm sorta glad Tim dove in fresh, maybe he just saw the films and in the end, that's the main thing really, the films. Everything else is the icing on the cake.
