In the beginning of the new GR. Blaze first arrived fresh after a long haul of not using the Rider. So when his enemies shot him with projectile grenades he went unconscious and awoke with bruises on his human body.
But later he tanked much more powerful bunker destroyer missiles and laughed them off.
Plasma blasts ain't doing squat to the Rider. And all it takes is a slight touch with either his body or the chains to turn the Predators into ash. For they are most definitely guilty of murder.
GR also showed signs of burst speed movement whilst on his feet. He can move fast in short confines.
Predators are screwed.
