Summary

Acnologia, known to be fearsomely reputed as the Dragon King, was a cataclysmically powerful Dragon Slayer that can take the form of a Dragon at any time due from his overuse of Dragon Slayer Magic and bathing in the blood of the Dragons he killed. He was referred to as 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.

Attack Potency: At least Large Island level+, likely far higher (Far stronger than Base Zeref) | Multi-Continent level, likely higher (Stronger than Fairy Heart Form Zeref, as even after Zeref had absorbed the Fairy Heart, he still believed he could not defeat the present Acnologia. It has been stated that Etherion would be needed to even contend with Acnologia. Implied that Ars-Magia would not be strong enough to defeat him. Should likely be stronger than the Dragon Cry, as even 400 years ago, when he was far weaker, he could easily overpower and kill thousands of Dragons, which are the source of power for the Dragon Cry itself) | Multi-Continent level, likely higher (Incomparably stronger than his previous Dragon Form, due to absorbing the Space Between Time, which has far more magic power than his previous Dragon Form. Incomparably stronger than the Dragon Gods) | Multi-Continent level, likely higher (At least 2x stronger than before, due to absorbing the Space Between Time, which has far more magic power than his previous Dragon Form. Stated to be the strongest character in the original series)

Durability: At least Large Island level+, likely far higher (More durable than Base Zeref) | Multi-Continent level, likely higher (As a Dragon, his durability is far above his offensive power due to having extremely durable scales. He took a direct powerful roar from Igneel and emerged completely unscathed. Should be as durable as Fairy Heart Form Zeref) | Multi-Continent level, likely higher (Tanked several attacks from Savage Dragon Fire Form Natsu. More durable than his previous Dragon Form) | Multi-Continent level, likely higher (As a Dragon, his durability is far above his offensive power due to having incredibly durable scales)

Stamina: Extremely large (Capable to fighting an entire war against two armies of thousands of dragons single-handidly and still come out as the only survivor. He can also eat magics to restore his magic power and stamina)

Range: Standard melee range. Several hundreds of meters to several kilometers with ranged attacks and senses.

Standard Equipment: None notable

Intelligence: Gifted (Has had hundreds of years of experience in battles and has knowledge of many different kinds of magic, being able to identify Irene as a High Enchantress almost immediately. However, after consuming the Space Between Time, his Human and Dragon forms are separated from, though still linked to, each other. While the human part retains his personality and intelligence, the dragon part becomes simply a beast with destruction as his sole objective. Nevertheless, the dragon part still can instinctively sense what it considers a threat and destroy the said threat)

Weaknesses: He is vulnerable to motion sickness as a consequence of the synchronization between the large gap of a human's semicircular canals and a Dragon's visual acuity. Like other users of Dragon Slayer Magic, Acnologia cannot eat the magic created from his Dragon Slayer Magic to replenish his stamina or to stop his reflected magic. After consuming the Space Between Time, his separated 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's 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 Arcane Dragon.

  • Arcane Dragon's Roar: Like all Dragons and Dragon Slayers, Acnologia can perform a Dragon's Roar, incorporating his element into a massive breath attack. As mentioned, the element Acnologia employs is pure Magic. Said blast, while he was a Dragon, was potent enough to "completely eradicate" the entirety of Tenrou Island and imprint a giant crater into the ocean.
  • Arcane Dragon's Eruption: Acnologia raises his hand and magic erupts from beneath his opponent.
  • Arcane Dragon's Blast: Acnologia raises his finger and fires a giant blast at his opponents.
  • Arcane Dragon's Breath: Acnologia opens his mouth and fires off a bunch of explosion blasts.
  • Arcane Dragon's Explosion: Acnologia exerts his magic in all directions, causing a huge explosion.
  • Eternal Flare: Acnologia casts starry lights in the sky, which rain down in a massive radius as beams with huge destructive force.

Time Magic: Acnologia after consuming the Space Between Time was able to wield this Caster Magic. With the power of time he was able to warp the seven Dragon Slayers into his world with a Rift in Space and Time.

Key: Human Form | Dragon Form | Human Form (Post-SBT) | Dragon Form (Post-SBT)
