Dragon

("リュ" Duragon) is a Third Generation pyrokinetic and leader of the White-Clad's Butchers.

Appearance
Dragon is a huge and incredibly muscular man with slited pupils and sharp teeth. While appearing to have male pattern baldness his remaining hair was still wild and dark. His uniform was primarily knightly armour underneath a white cloak, most notably his arms were protected by armour resembling scales. He was barefoot when in battle. Dragon’s height seemed to vary in certain situations. He usually seemed much larger when attacking.

Personality
Dragon is extremely confident in his abilities as a killer, claiming that all who stand in his way will fall. When Gold told him to avoid failure, he belittled her before reminding her of his status as a Butcher. He also belittles Charon for his weakness when the Guardian is injured. This confidence lead him to see himself as beyond human, simply identifying himself as 'Dragon' and even advising his enemies how to fight against him or complementing their abilities during their battle. He relished a good fight and encouraged Arthur Boyle's delusions of knighthood just to see if the boy would prove a suitable challenge. Once he finally finds somebody capable of hurting him, he was gleeful at the possibility of a 'real' fight. In fact, Dragon's behaviour implies that truly defeating Arthur and breaking his spirit is the only thing on the planet that matters to him.

As he inspired despair in all he encounters, Dragon believed that hope or optimism were worthless in the face of his overwhelming power. He did not find pleasure in this, as discarding these feelings lead Dragon to endless boredom without an alternative. This boredom motivated him to work with the White Clad simply to have purpose. Without that goal, he was perfectly willing to spend eternity alone.

Background
Sometime after the Great Cataclysm, he appeared in Iraq. Leaving a path of ashes and being viewed by people as a walking disaster, the boy was nicknamed "Dragon". With nothing to live for and no goals of his own, Dragon spent years wondering the lands and destroying whatever he choose in an attempts to alleviate his boredom and misery. As an adult, he encountered Faerie and the boy promised that in 200 years they would be able to lay waste to the entire world. Finally with a goal to pursue, Dragon follows the child he sees as an insect although his despair remains.

Abilities
Dragon is an enormously powerful figure who was able to easily defeat Arthur without suffering any injuries, despite Arthur fully embracing his knightly delusions as he had finally found a "dragon" to slay. He also destroyed Excalibur in the process. Even Benimaru, the strongest fighter in the entirety of the Special Fire Force, was unsure he could defeat the White-Clad by himself with Dragon around, calling him a monster after proving unharmed from Benimaru's attacks.

In addition to his astonishing physical strength, Dragon is highly durable and resilient, being able to survive a number of attacks from a super-heated plasma blade without flinching. Mysteriously and without any movement, even if bombarded with attacks, Dragon remains unhurt while his opponent slowly gain new injuries merely by being in his presence. All these are are the sum of an ability he calls "Draconic Pressure". His durability is so vast that he could survive being blasted into space by an energy beam equivalent in power to a nuclear bomb. He was also able to survive in space with no issue before deciding to return to the Earth to fulfill his role in defeating Arthur Boyle and shattering the knight king’s spirit.

Dragon possesses an enhanced lifespan granted to him via the Evangelist. He managed to survive for 200 years after the great cataclysm.

Pyrokinesis
Dragon has the ability to breathe a stream of fire out of his mouth. Upon reaching close proximity of his enemies, the flames detonate into a large explosion.

He also has the never-before-seen ability to "Infernalize" himself at will, granting him the physical characteristics of a Demon Infernal, massively increased firepower, and the ability to fly using his flaming wings. When using this ability, the affected body parts become darker and more durable. This allows him to protect himself with "Dragon Scales". Dragon is able to use this ability on his entire body, calling it "Dragon Coordinate".

Ōbi's Rescue arc
Upon Akitaru Ōbi being imprisoned at Fuchū Prison, the Butchers prepared for Special Fire Force Company 8's arrival. After Stream is defeated by Arthur Boyle, Dragon confronts the Fire Soldier, questioning if his opponent is feeling intimidated facing a dragon for the first time. He then breathes out a gust of flames which cripples the company with the exception of Arthur. Slashed by Arthur with enough force to cut a building, Dragon withstands the attack before pushing him away. Easily withstanding more of Excalibur's attacks and Hinawa's gunfire, Dragon breathed more flames, but Arthur defends himself using his Plasmantle.

Continuing the fight, Dragon's reveals his scales to his opponents that cause Arthur to suffer whenever he attacks Dragon. He then coats his arm in these scales and transforms his arm into a claw before striking him back. As Arthur increases the size of Excalibur using his delusions and the support of his friends: he swings his "Dragon Killing Holy Sword" at Dragon, only for Excalibur to shatter. Dragon then tries to attack the rest of Company 8, but is halted by Benimaru Shinmon and is held off until Company 8 can escape to safety.

Amaterasu arc
Dragon appears in this arc and faces off against Company 8 when they try to reach the Amaterasu Power Plant to stop the White Clad from initiating the Second Cataclysm. Dragon faces off against Arthur once again and compliments the boy on his increased skill. During their battle, Dragon is blasted into space when Takehisa Hinawa uses his Trajectory Control to redirect a massive suicidal energy blast from Charon, though Arthur doubts that this would have destroyed him. Dragon later appears alive and unharmed floating in space, pondering whether he should stay and let himself die in hopes of becoming a living star. During his ennui, Dragon remembers Arthur and is intrigued by the boy's fearless determination in spite of the coming apocalypse, so he decides to return to Earth to show Arthur the fear of being killed by him.

Upon re-entering the atmosphere, Dragon shouts out demanding Arthur's presence. Upon a volcano near to Tama Bay, he waits. Arthur appears, vowing to free Dragon from his despair and save the world. Dragon is interested when Arthur grazes his cheek. When Dragon knocks Arthur into the air, the knight hides in a thunderstorm to draw the energy into his blade and cuts Dragon deeply enough to draw blood. Dragon cackles with laughter and finally acknowledges Arthur as a person and opponents before continuing the fight. Arthur launches a counterattack to Dragon's flame, forcing Dragon to block for the first time in his life before hammering the Fire Solider into the ocean. Dragon pursues his foe into the depths where Arthur uses the water to conduct his plasma to shock Dragon, who counters by splitting the sea itself and declares that the world feels too small for both him and Arthur to exist.
