In the Tower of Heaven arc, there’s a dude with an owl head, Millianna has legit cat ears, some guy in the Wizard saints has pointed ears, Wally was made of blocks, Juvia is made of water, Gray and Lyon can survive in below freezing temperatures naked, there’s that purple dude from Raven Tail, NATSU EATS FIRE AS AN ACTUAL LEGITIMATE FORM OF SUSTENANCE, Carla turns into a humanoid form and was mistaken for a human... HOW COULD THEY TELL THE TARTAROS DEMONS WEREN’T HUMAN? With all the strange features going on in Fiore, HOW could they tell that this one guild was not human just by looking at them?

The first demon we see in the series is a flute, an inanimate object turned demon through Zeref’s magic.

The next set of demons related to Zeref we see all have some sort of animalistic features either in their first or second form. Or in the case of Franmalth and Keyes just straight up living matter. So it might be safe to say that Zeref had moved to turning living objects into demons. (Silver isn't counted in this since Keyes was the one who made him a demon)

And then lacarde here now was the closest to human in terms of appearance in comparison to Zeref’s other demons, so it was possible he was made a little bit before Natsu or perhaps after Zeref gave Natsu to Igneel to raise so he could go back to the drawing board and work out a few kinks.

What I'm basically getting at here is that all the demons we saw in the series were most likely experiments before Zeref finished creating an Etherious body to revive Natsu.

But the question now is, where does Natsu fall?

Since we never saw his Etherious form would natsu fall into the animal based demons with tartarus (with a body that's a mix of demon particles, human dna and animal dna) or the latter with lacarde ( a body that's just demon particles and human dna).

Natsu creates an explosion on Franmalth.
