id say that natsu is actually part of E.N.D, which is why zerif knows his name, because he created him. he was separated from his "other self" when ignial fought against E.N.D and so lost his memories. he is actually a demon but his body naturally adapted "growth"(from observing humans growth) and so he grows much like a human. the form we are shown is not his real form as he simply adopted the look of a human, though he has no memories of this. the reason he charges at zerif is due to a command from years back 'destroy me' or something like that……… ignial taught and raised him because he knew that natsu was meant to destroy zerif he gave him the scarf to protect him from his own darkness, and as zerif was his creator his darkness is natsu's darkness, this is why is scarf absorbs zerifs power.
