Arthur

Biodata

Power Progression

Arthur’s system rewards qualifying victories with enhancements. Its achievement quests also unlock Noble Phantasms; later, he gains powers from other worlds 1 46 168.

Background and History

Arthur was a shut-in in his previous life. He went to sleep and woke in the world of One Piece in another body, having acquired an Arthur Pendragon template and access to a game system. He had spent half a year in that world by the time he appeared in Orange Town 1.

He accepted the Arthur Pendragon identity, but did not draw Caliburn, rule Britain, or establish the historical Knights of the Round Table. His original aim was to complete the system’s achievement quests and explore the world rather than become Pirate King or overthrow the World Government 25 144 160.

Voyage and the Paramount War

Arthur defeated Buggy, gave money to Orange Town’s residents, and accepted Nami as his navigator and partner. Robin later joined them. After training on Whiskey Peak, the three traveled to Sky Island aboard Arthur’s flying horse, Dong Stallion 3 11 23 25.

At the Paramount War, Arthur fought for the Marines as a hired third party. He defeated Jozu, fought Marco and other Whitebeard Pirates, and reached sixty consecutive victories by defeating Doma. He chose not to expose the Rumble-Rumble Fruit’s power in a prolonged fight with Whitebeard 46 49 52 58.

Arthur subsequently fought the Blackbeard Pirates, challenged Kaido, and defeated Mihawk. After further training and victories, he confronted Charlotte Linlin on Whole Cake Island. He later fought Whitebeard on Decalvan Island and completed the quests that awakened Rhongomyniad and Avalon 71 76 89 116 138 142.

Other Worlds

Arthur entered the Fourth Holy Grail War as Kayneth’s Lancer, operating in a Heroic Spirit state while his original body slept in Avalon. He killed Zouken Matou, rescued Sakura, and was declared the war’s victor. He also met Saber, Artoria Pendragon, another world’s King Arthur 144 155 160 161.

In a world of Heretic Gods, Arthur became a God Slayer and settled temporarily on Sardinia with Saber and Erica. He defeated Athena, spared her, and made her his maid while allowing her regular chances to reclaim the Gorgon Stone 168 176 178.

In another world, Arthur obtained the Boosted Gear, trained Koneko Toujou, and became known as the Red Dragon Emperor. He defeated his counterpart Vali and later revealed his identity as Arthur Pendragon from another world at Kuoh Academy 194 200 218 227.

In Little Garden, Arthur received Host Master Authority and met Izayoi Sakamaki. He later claimed the former Perseus palace as a base named Avalon and arranged a fight with Izayoi 243 260.

Appearance

Arthur is a handsome blond man with emerald-green eyes and a noble, knightly bearing 10 51.

• Height and weight: 181 cm and 69 kg 1.
• Knight’s attire: A white upper garment with a long cape-like coat, white trousers, boots, and gloves 10.
• Armor: He can change his knight’s clothing into pale silver armor 177.

Personality

Arthur is easygoing and habitually lazy, often preferring leisure to training. His repeated victories and system enhancements nevertheless changed him from a fearful newcomer into a confident fighter. He recognized that his reliance on Future Sight and overwhelming power had also made him somewhat arrogant 11 51 116.

He values freedom over political authority or wealth, treating Avalon as his home and other worlds as places he visits. Though capable of elaborate schemes and deception, he dislikes being manipulated and is willing to keep his system secret even from those closest to him 100 209 222 225.

Arthur can be protective and compassionate: he rescued Sakura, offered to avenge Akeno, and considers the feelings of his companions when making romantic decisions. He can also be calculating, as when he withheld the Holy Grail’s corruption from Saber 155 161 176 219.

Abilities and Skills

Swordsmanship and Excalibur

Arthur inherited King Arthur’s sword experience when he awakened Excalibur, then adapted it to the swordsmanship of the sea world 1 8.

• Uses flying slashes and mana-compressed sword pressure; Excalibur’s True Name Release produces a destructive golden torrent 1 51.
• Can conceal the blade with Invisible Air and coat it in Armament Haki, making its dimensions difficult for an opponent to judge 17.
• Powerful releases consume substantial mana. During the fight with Whitebeard, Arthur could not release seven of Excalibur’s seals before Avalon awakened 51 137.

Haki and Instinct

Arthur possesses Observation, Armament, and Conqueror’s Haki, as well as the innate skill Instinct 78 142.

• Future Sight: Instinct initially allowed him to anticipate attacks; his Rumble-Rumble-enhanced Observation Haki later reached A++ 17 26.
• Armament Haki: Reinforces his body and weapons and can be combined with Mana Burst 46.
• Conqueror’s Haki: Awakened as his spirit developed and rose to A++ by the time his achievement quests were complete 116 142.
• Whitebeard developed a way to counter Arthur’s Future Sight and landed a surprise blow during their Decalvan fight 138.

Rumble-Rumble Fruit

Arthur uses the fruit’s lightning power indirectly: the Holy Lance, rather than Arthur himself, consumed it 109 112.

• Boosts his physical attributes, enables lightning movement and elemental transformation, and enhances Observation Haki through radio waves 26 102 116.
• Techniques include Divine Judgment, Railgun, the 200 Million Volt Thunder Lance, and the 500 Million Volt Spear of Judgment 116 134.
• Raigo depends on thunderclouds but requires comparatively little stamina when they are available. Arthur cannot develop the fruit to a higher level in the usual way because he did not eat it himself 109 114.

God Slayer Authorities

After killing Heretic Gods, Arthur gained a greatly strengthened constitution and divine Authorities. His first such victory granted the Authority of Sun; Fusion EX later combined his Authorities into Ten Incarnations 168 189 201.

• His God Slayer physique corrected a major earlier weakness: without Mana Burst or Armament Haki, his former body was vulnerable to physical blows 164 168.
• He used the Authority of Thunder to annihilate invading magicians at Kuoh Academy 227.

Reality Marble

After finding a book on Reality Marbles in the Matou mansion, Arthur began developing his own. He manifested memories of a beach and a collapsing island in a dream, but the unstable effort exhausted him 155.

Boosted Gear

Arthur obtained the Red Dragon Emperor’s Gauntlet and studied how its Infinite Boost and Dragon Emperor’s Gift could amplify his power and help release Excalibur’s seals 200 205.
