Arthur is an oblivious third generation with delusions of being a king, abandoned by his parents who left to travel the world after their small restaurant burned to the ground. An exceptionally strong Fire Soldier, Arthur's Ignition Ability relies on his delusions, which allows him to fabricate and control plasma which he uses in the formation of his sword Excalibur, allowing him to cut, weld and manipulate electricity. The more detached he is from reality, the more powerful he become. He and Shinra developed a bitter rivalry back in their training days, which did not disappear even after both joined the same company although the rivalry has since toned down to a more friendly one.
