Acnologia

Acnologia's preferred appearance is that of his human form, which is that of a rather muscular young man with long, dark blue-colored hair. He carries a sharp gaze; his eyes have black circles around them. He is dark-skinned, and on his body he bears the same light blue markings he does when he is a Dragon. For attire, Acnologia dons a high collared, black cloak (which also bears his draconian markings), sharp red claws around his neck, a sash around his waist, a gold arm ring tightened around his right upper arm, and baggy pants which are decorated the same as the most former article of clothing.

As a Dragon, Acnologia is mastodonic, and has an entire upper body covered in black, round, scales, which, in turn, are decorated by spiraling, blue markings. His lower body, specifically his chin, chest, stomach, inner tail, thighs, and arms, are gray in color, and appear to be rather smooth. Acnologia's eyes are white and beady, and his head is round and blunt with four, large, elongated plates extending backward. Acnologia's mouth is full of razor-sharp teeth, and, attached to his chin, is a protrusion that resembles an arrowhead. His large wings are feathery in appearance, akin to a bird's, and very similar to fellow Dragon Grandeeney's. The scales disappear at the end of Acnologia's tail, which, in itself, ends in a stinger-esque shape. , Acnologia was a ruthless, bloodthirsty, and violent person. He killed any and all Dragons he could, ignoring the fact that many were his comrades. Acnologia is a ruthless, bloodthirsty, and violent person. He killed any and all Dragons he could, ignoring the fact that many were his comrades In the present, Acnologia is a recluse who wants nothing to do with humans, in spite of the fact that he is one. As Zeref Dragneel puts it, he sees other humans as nothing more than insects, ignoring any and all attempts by them to converse, which suggests that Acnologia is highly arrogant.[13] However, inversely, Acnologia's motives are also shrouded in mystery, as even with one arm he, according to Zeref, has the power to rule the world yet elects not to do so. Insights into his wishes have only been touched upon by outside sources, which include his vague desire to fight against humanity, as well as face an opponent strong enough to give him a real challenge. Ultimately, in a form of irony, despite his inherent hatred for humanity, Acnologia prefers to take on the shape of his old human form in casual instances. History

Born over 400 years ago, Acnologia was a doctor in a hidden land before becoming one of the first Dragon Slayers to come into being, entering the Dragon King Festival on the side supporting coexistence, being that Dragons were the very ones who murdered his family and destroyed his city. Acnologia and a group of other Dragon Slayers, however, became corrupted by their power and disregarded the cause their comrades fought for, killing every Dragon they could, and bathing in their blood. After encountering a gang who fatally injured Sonya, Acnologia killed all of them in reprieve for the child. He then came upon her wounded body, promising he'll slay every Dragon after he couldn't save her life. Due to the overuse of his Magic, Acnologia's physique eventually morphed into that of a Dragon's, and he proclaimed himself to be the Dragon King. This event was forever etched into history as the Dragon King Festival.
