Yet you kept on arguing and yapping that Natsu will transform into E.N.D., while people are telling you that Natsu IS E.N.D.

Yes he's hands is changing/transforming but that's just the result of Natsu using his powers. It's not like Natsu is changing into something different.

Here's the thing, Natsu IS an Etherious, that's a known fact. It won't be surprising that he has Demon/Etherious power in him but it doesn't make sense to say that Natsu is transforming into E.N.D. when he is E.N.D.

How does Natsu have to further transform into an Etherious when he already is one? That's like saying a human is transforming into a human.
