The Legend Starting from Roger Ship

[Old Era + Slow Heat + Gradual Growth + Swordsman + Three-Color Dominance + Ice Element + Half Lone Wolf]

Arthur travels through the world of One Piece. With his tough physique, he goes from being the strongest genius in the history of the navy to being a prisoner framed by a conspiracy of the Warring States.

Twenty years ago, he wandered between various forces, avoiding the pursuit of the navy and the assassination of the Celestial Dragons.

He was a member of Roger's pirate crew. At the age of 16, his swordsmanship was on par with Rayleigh, and at the age of 18, his swordsmanship was on par with Roger...

After Roger surrendered himself, Arthur, who had no background and no identity, was hunted down by the World Government and the Navy.

This caused him to suffer life-threatening battles since the beginning of the Great Pirate Era.
