Bellerophon

Ancalagon is the son of Vritra, one of the five Dragon Kings, and descendant of Bellerophon from the Trojan War era, which means that he's distantly related to the Greek god Poseidon.

Appearance
In his human form Ancalagon appears as a rather muscular fair-skinned man with waist-lenght, spiky raven hair and shoulder-length bangs framing the sides of his face. His violet eyes carry a sharp gaze and his body bears the same light blue markings he does when in his True form.

Personality
Ancalagon's childhood was a product of the times he lived in: the constant fighting made him a perfectionist that would keep working at something until he mastered it and his successes in battle made him very confident in his abilities. Stemming from this he generally respects those that work hard for their skills and abilities, regardless of power, while acting dismissive towards those that rest on their laurels.

In casual instances Ancalagon displays an apparent happy, carefree and even teasing personality, often wisecracking and making crude jokes in an attempt to fluster and put other's off balance. When the situation calls for  it he's much more cynical and serious, and often mocks and taunts others for their stupidity or naïveté.

In battle Ancalagon retains a stoic and composed personality, never allowing his failed plans to upset him. He loves fighting above all else and is constantly looking for a worthy challenge, showing a more excited side to himself whenever he finds one, and even praising his opponents if they manage to surprise him or survive his onslaught.

"Not accepting defeat and getting up again is simply unsightly..."

- Ancalagon

Because of his power he often imposes limitations on himself, such as relying on his depowered form. He doesn't feign modesty, bluntly stating that he is stronger than his opponents and belittling them when they keep fighting against the inevitable, however if he is proven wrong about something he would admit it, apologise for previous remarks if necessary, and conclude the fight swiftly without dragging out his opponent's misery.

Because of several factors, such as his immortality and curiosity, Ancalagon exhibites a boundless lust for knowledge of any kind, specifically on the mechanics behind magic styles and spells but in recent years he's taken an interest in human sciences. His divinity granted him the ability to retain all acquired knowledge forever.

In his True form Ancalagon often becomes ruthless and bloodthirsty in combat, often aiming to inflict great pain to his opponents before killing them. He sees most other beingsas nothing more than insects, ignoring any and all attempts by them to converse, and generally exhibits a mercurial temper when dealing with annoying situations or individuals, not hesitating to remove them if the situation is favorable.

Through direct physical contact he is capable of transforming people and objects into fine dust.


 * Anti-Magic: Only accessible in his True form or Dragonoid form. Ancalagon can generate a white flaming aura around his body that makes him extremely resilient to magic, outright dispelling most supernatural attacks or progressively weakening them until they disappear, although it offers no protection from physical attacks. While in use it prevents him from casting spells. He can channel his Anti-Magic powers as direct attacks or through his body for additional damage to supernatural beings, stripping away magical defenses and weakening the targets once hit.

 * Telepathy: Ancalagon can converse telepathically with people and even with the beings held within Sacred Gears, such as Draig.

He can also use this ability on a single part of his body, such as a limb, by teleporting it close to an enemy in order to blindside the target.


 * Barriers: Ancalagon can deploy several types of barrier spells, from detection wards to nigh-invulnerable bulwarks.
 * Blue Flame Formation: A cylindrical blue barrier which envelops a location of his choosing, protecting anything contained within and burning whatever comes into contact with it. This barrier is powerful enough to withstand the assault of a High-class Devil without reporting visible damage.
 * Red Lightning Formation: After shooting six glowing spheres around the targeted area, Ancalagon forms this hexagonal red barrier capable of electrocuting and disintegrating anything that comes into contact with it, while stopping all forms of space-time manipulation. This barrier is powerful enough to perfectly contain a Heavenly Dragon-class opponent.
 * White Void Sphere: By using the principles of the Sacreed Gear Dimension Lost, Ancalagon claps his hands together and generates an expanding white sphere from his body capable of transporting everything it touches into a parallel dimension. Although everything can be seen from one side to the other of the barrier, interaction between the two is impossible. All forms of teleportation are blocked inside the barrier and because of how it's built it cannot be broken or bypassed unless Ancalagon interrupts the spell.


 * Runes and Seals: His studies allow him to inscribe and form runes and seals effortlessly, with purposes varying from silencing a target, putting it to sleep, summoning, warding off areas, shielding his presence.
 * Power Seal: When placed on himself it allows Ancalagon to seal away most of his powers into a pocket space connected to the seal itself, making him enter a depowered humanoid form. In case he suffers critical damage the seal automatically opens, releasing all of his powers in an instant, which causes his body to quiver and shatter apart with his draconic form bursting from within. As his previous body is discarded his new form will be completely uninjured.
