Who is Acnologia?


Is Acnologia a human or a Dragon? In Fairy Tail, it is shown that he was a
Dragon Slayer who had transformed into a Dragon. But, who was he before
becoming a Dragon?




As [Quikstryke's answer](https://anime.stackexchange.com/a/19238/1398) said,
Acnologia was one of the first Dragon slayers. The more he fought with dragon
magic, the more he became dragon-like.

In a recent manga chapter, it is revealed that

> Igneel and the other dragons were "alive/dead" inside the dragon slayers,
> and as the dragon slayers matured, the dragons inside them prevented the
> dragon magic from consuming them and turning them into dragons like
> Acnologia's case.
