there's actually a very simple way to predict the Supernova. the 'Teo Timer', which is about 90 seconds, starts as soon as he roars when he gets furious, and he does the Supernova at the end of the timer, when rage mode goes off. You just have to count in your head and get away from him at ~80 seconds.
