lt's not just a new form if its kaido's awakening.. Was it Enel and Moria's awakening?.. lf you compare to someone it should be Doflamingo the difference is kaido's using his awakening after Luffy's because he didn't need to use it prior to now..
lt goes back to what kaido was saying before in the last chapter if Luffy doesn't show a Haki feat he won't beat him..
kaido's awakening > Luffy's awakening
