i believe that ever since fighting gerad in ToP arc, his emotions are enhancing his powers and this is the true ability of ds cos in every arc afterwards, natsu's abilities are growing stronger and faster and even though he doesn't know it, he doesn't need to eat flames to recharge his powers and increase them all of the time. Like with Cobra, the dragon's roar was like a hidden power and now after fighting zero, it's increasing faster
