Tekken Arthur is one of six wielders chosen by a variant of the sacred sword Excalibur, manifesting as a powerful gauntlet. His mission drives him to England alongside the group to confront others wielding corrupted Excalibur variants and halt their distortion of history.

He possesses a brash, reckless, and persistently hot-blooded personality, tackling his duties with unyielding enthusiasm. Tekken deeply values friendship and camaraderie, often charging headstrong into battles. In combat, he relies entirely on his gauntlet Excalibur for direct physical confrontation, leveraging his muscular build to overpower opponents through sheer strength.

His interactions include a close collaboration with Kakka Arthur during a mining town mission. While Tekken thrived on the strenuous labor, Kakka faltered; their combined efforts ultimately exposed corporate corruption, sparking peer speculation about a potential special bond between them. At a beach resort, Tekken participated in guarding swimsuit contest participants against a thief, demonstrating vigilant protective behavior.
