Quote#ThePredator homeworld has sent their two best champions to Earth and they haven't returned. They're pissed.
So yeah... I don't care for this one bit. Isn't the whole point of the hunt to be challenging? If you try to hunt challenging prey that's worthy of your time, there is, you know, the risk of dying. So why would they be pissed? And why would be Predator in the 2nd Movie even reward Harrigan, if killing their champions is some sort of affront?
