Background

Arthur was created by Uther Pendragon as an artificial Savior intended to surpass Artoria. His construction used a superior Heart of the Red Dragon, Dragon Factor, and a soul obtained from roughly fifteen hundred years in the future. Uther and Merlin also incorporated concepts including ambition, desire, military strategy, political strategy, capability, and justice. Arthur is conceptually part of the Pendragon family, but has no blood relation to Artoria. 51

He begins as Artorius II, Britannia’s crown prince and Artoria’s designated heir. Although praised for his talent in martial training, mathematics, administration, rhetoric, and literature, he privately conducts magical and technological research through a workshop connected to Merlin’s. 1 2 3

Arthur’s early goal is preventing Britannia’s destruction as Aether fades. Unlike Artoria’s attempt to preserve the old order, he advocates cooperation and intermarriage with the Saxons, Roman alignment, continental expansion, and ultimately the reconstruction of the Western Roman Empire. 7 8 9

Appearance

Arthur is introduced as a strikingly beautiful thirteen-year-old prince whose appearance is considered exceptional even by Britannian standards. After absorbing Vortigern’s power, his skin becomes fairer and his hair lightens toward snow white. 1 6 8

• Recognized as a bishōnen throughout Britannia. 2 6
• Possesses pale skin and increasingly light, nearly snow-white hair after his transformation. 8
• Commonly presents himself in noble attire or military equipment appropriate to his position as prince, king, and commander. 20 38
• Carries the visible presence of a dragon-blooded warrior and ruler when exerting his power. 8 26

Personality

Arthur is ambitious, pragmatic, and intensely future-oriented. He prefers shaping states, organizations, and armies over personal combat, finding satisfaction in making a country prosperous, building effective systems, and commanding invincible forces. 35

He is also charismatic and highly persuasive. His appeal differs from Artoria’s royal majesty: Arthur inspires followers by offering advancement, wealth, recognition, and a place in a larger undertaking regardless of their birth or background. 12 16

Despite his manipulative tendencies and willingness to use coercion, assassination, and political pressure, Arthur repeatedly frames his long-term ambition around saving humanity from decline, fate, and the Counter Force. He becomes increasingly willing to accept personal sacrifice for that objective. 49 55 60 163

Arthur can be playful, vain, and irreverent in private. He often jokes during dangerous situations, pursues women with calculated charm, and treats his extraordinary appeal as a practical political asset. 1 5 23

Abilities & Skills

Equipment / Weapons / Items

Relationships

• Morgan le Fay — Arthur’s aunt, magical adviser, and key collaborator in the destiny ritual. Their relationship evolves from mutual manipulation and hostility into cooperation. 19 57

• Galahad — Fellow knight and battlefield companion whose sacrifice enables Arthur to absorb the Holy Grail’s power and become king. 5 49
• Merlin — Early magical facilitator and persistent provocateur. Arthur distrusts Merlin’s unreliability but continues to use his expertise when necessary. 2 3 54
• Maeve — Initially encounters Arthur in the Inner Sea of Stars; centuries later, she becomes the first Imperial Heroic Spirit after Arthur saves her from decline. 26 172
• Alexander — Rival conqueror whom Arthur defeats rather than kills, eventually persuading him to join an exploration effort. 107
• Artoria Species — Numerous alternate Artorias regard Arthur as the legendary “oneson,” while Arthur treats them as both family and a political force. 120 142

Story Role / Major Arcs

Britannian Crown Prince

Arthur begins as Britannia’s heir under Artoria’s rule. After losing a training bout to Agravain, he continues to develop his swordsmanship, magecraft, and independent political vision while investigating how to save a collapsing Britannia. 1 3

Saxon Integration and Continental Ambition

After Vortigern’s death, Arthur inherits much of his power and authority. He claims the title of Vortigern’s heir before the Saxons, persuades them to follow him south, and proposes a future built on Celtic-Saxon integration and continental conquest. 8 9

Germanic Commander

Arthur recruits a multinational force, swears fealty to Lucius Tiberius as a strategic step, and leads Britannian knights and Saxons into Europa. His victories, agricultural policies, and recruitment practices turn the Germanic War Zone into the foundation of his independent power. 12 16 17

King of Britannia

Galahad’s sacrifice allows Arthur to gain the Holy Grail’s power. Artoria abdicates in his favor, and the Knights of the Round Table recognize Arthur as King of Britannia. He then centralizes the island’s fractured kingdoms through political pressure, alliances, and force. 49 50 56

Usurpation of Destiny

Arthur forms the Illuminati with Morgan, Scathach, Vivian, Merlin, Artoria, and other allies to steal the Franks’ destiny. He kills Clovis, absorbs the resulting legitimacy, and becomes the Germans’ Emperor. 54 63 64

Dragon Emperor

As Dragon Emperor, Arthur expands through Hispania, Gaul, Italy, North Africa, and beyond while establishing android administration, magical-industrial research, and a central imperial state. He prioritizes long-term human advancement over the old heroic age. 70 72 160

New Human History

Arthur advances from ruling an empire to modifying Servants, Singularities, history, and human order itself. He seeks to replace Pan-Human History with a New Human History under human control, eventually sustaining an Eternal Age of Gods through stellar energy and True Aether. 172 199 285 288

Trivia

• Arthur’s early Heroic Spirit profile lists adaptability to Saber, Lancer, Caster, Assassin, Berserker, and Rider classes; Archer compatibility is added after the appearance of the Smoky Flash. 1
• He prefers leading nations and armies to personally fighting, despite being one of the setting’s strongest combatants. 35
• Arthur created the world’s first firearm but initially sealed it away because of history’s constraints. 161
• The public “Crown Prince Artorius II” who succeeds the Dragon Emperor is later revealed to be a magical puppet; Arthur never truly relinquishes power. 171
