i think that natsu is a very powerful demon that zeref created bc in loads of episodes when natsu is fighting the enemy reverses to him as a demon (or something like that) and zeref wants natsu to kill him thats y he created him and natsu has no family other than igneel which shows he may of not had a family to begin with
