Dragon's death battle

Acnologia Apocalypse dragon(Fairy tail) 1

Now to start with the dangerous category of dragons and the main antagonist of Fairy Tail for slaughtering many of the dragons. For this battle I will be using his dragon form only not his human since this won't have a well ending for the opponents. Acnologia also known as The Black Dragon and fearsomely reputed as the Dragon King, was a cataclysmically powerful dragon slayers that can take the form of a dragon at any time due from his overuse of Dragon Slayer Magic and bathing blood of the dragons he killed. He was referred as a doctor in his early life that took care of dragons but due to them murdering his family, destroying his city, and "claiming the life of a child", he took it upon himself using the name of the dragon whom he despised to slay every dragon in existence, believing they only cause destruction and pain.

While the human part retains his personality and intelligence, the dragon part becomes a simply a beast with destruction as his sole objective. Nerveless, the dragon part can still instinctively sense what it considers a threat and destroys the said threat)

Weakness: He is vulnerable to motion sickness as a consequence of the synchronization between the large gap of a human semicircular canals and a Dragon visual acuity.

After consuming the space between time, he separates dragon and human parts are linked to each other and should one part be restrained so will the other.        

Notable Attacks/Techniques: 

Arcane Dragon Slayer Magic: As one of the first humans who entered the Dragon King festival, Acnologia was also among the first dragon slayers brought into existence. Over time, however, as he slew many dragons, he himself was, eventually turned into a dragon due to the extensive overuse of his Lost magic. Acnologia, contrary to the legends surrounding him did not entirely become a dragon and has retained the ability to enter and exit his extremely powerful dragon form at will. Acnologia Dragon slayer magic also grants him the ability to reap the very souls of dragons leaving them in a half dead state. Acnologia has also stated that he has no element, as devouring and bathing in the blood of countless dragons has allowed him to be able to consume any type of magic to replenish himself, which gave him the name of the Dragon of Magic. 

Arcane Dragon Roar: Like all dragon and dragon slayers, Acnologia can perform a dragon roar incorporating his element into a massive breath attack. While, as mentioned, which element acnologia employs is pure magic, said blast, while he was a dragon, was potent enough to completely eradicate the entirely of Tenrou Island and giant crater into the ocean.
