The only time Natsu has been using Igneel's power was the Fire Dragon King's nonsense. I'm not saying all of Natsu's power is derived from Igneel. I am saying that when he cast Demolition Fist and the one (to possibly two) times he used the King's Roar, he was using Igneel's power, hence the spell's name of Fire Dragon King. There has been a lot that Natsu has done of his own power, for sure, but slaying a god wasn't one of them. When did it ever have to be said that he had to remove the bandages to use the power? It didn't, it was just done so that it was "secretive".
