Arthur Pendragon is a member of the Vali Team that was previously affiliated with the Khaos Brigade. He is a descendant of King Arthur, as well as a descendant of the witch Morgan le Fay, and is the older brother of Le Fay Pendragon.
He was one of the two best swordsmen of the Khaos Brigade alongside Siegfried of the Hero Faction and is known as The Strongest Holy Sword User.
Arthur is a bespectacled young man with blond hair with a strand of hair across his face, who is usually dressed in a business suit.
Arthur is calm, polite, and a gentleman. He appears to be obsessed in finding an opponent suitable for his Holy King Sword, Caliburn.
Arthur comes from the noble House of the Pendragon which consists of the descendants of King Arthur. He left the house after taking the Holy King Sword with him becoming an outcast and joining the Khaos Brigade in an attempt to seek strong foes. Arthur was originally part of the Hero Faction where he was Siegfried's rival before leaving the Hero Faction to join the Vali Team.
In Volume 6, Arthur appears alongside Vali and Bikou, saving Asia as they were scouting the Dimensional Gap, witnessing Issei's Juggernaut Drive and the appearance of the Great Red. He then leaves the Underworld along with Vali and Bikou after reintroducing himself this time to Xenovia and Yuuto Kiba.
He reappears in Volume 7, helping his fellow Vali Team members in the fight against Loki and Fenrir, killing one of Fenrir's sons before using his Excalibur Ruler to subjugate Fenrir after Vali weakens the wolf with his Juggernaut Drive.
In the beginning of Volume 12, he and the other members of the Vali Team were hiding in the Gremory Palace while waiting for Vali to recover from Samael's poison. He later attacks Hades' Palace along with the other members of the Vali Team, successfully killing many Grim Reapers under Hades. He is later seen reporting to Vali who was with Sairaorg Bael and the Gremory Team, challenging Yuuto after deeming him to be a worthy opponent for his Holy King Sword, telling Yuuto that he will fight him when Vali fights Issei.
In Volume 15, Arthur appears alongside Vali, Bikou and Fenrir inside the Carmilla Territory of the Vampires, meeting up with Azazel who was at the Carmilla Territory at that time, to discuss with Azazel about the re-emergence of the Evil Dragons, the Vampires, the Holy Grail and Euclid Lucifuge.
In Volume 16, Arthur, along with Bikou and Fenrir, battled with the possessor of the Longinus, Incinerate Anthem, and the magicians from Hexennacht. He later participated in the meeting for the formation of D×D and asked Issei if he can make a pact with his younger sister, Le Fay, in which Issei agreed to.
Arthur participated in the fight against the exorcists that rebelled against the Church in Volume 19. He volunteered to be Yuuto's replacement to fight against the group led by Vasco Strada as Yuuto wanted to fight against Ewald Cristaldi. Arthur was able to fight evenly against Strada although both of them were not serious. After a small exchange, Arthur backed off from the fight saying that if only Strada was 20 years younger, they would have had the best fight and left right after.
In Volume 20, Arthur and other members of the Vali Team were on a mission to find the location of the stolen City that Qlippoth are using as their based of operation. They sent Le Fay and Kuroka to inform the others who later joined the fight against Qlippoth.
In Volume 21, the entire Vali Team alongside Tobio Ikuse and Lavinia Reni were sent to the Northern Europe region to prepare for Qlippoth's attack where they battled the army of Evil Dragons and fake Scale Mails while Vali goes up against Aži Dahāka. Upon the war's conclusion when Azazel and the other Mythology leaders prepare to seal Trihexa along with themselves, he tells Arthur and the rest of his team to look after Vali while he's gone.
In Volume 22, Arthur and the rest of the Vali Team goes fishing with the Occult Research Club and Issei's parents, with Arthur helping Le Fay attach the insect to fishing rod's hook after the latter was scared. He told Le Fay that a witch shouldn't be afraid of a little insect, while giving a brotherly smile.
