Mr. 1, whose real name is Daz Bones, is a major antagonist in the film One Piece: The Desert Princess and the Pirates: Adventures in Alabasta. He serves as the highest-ranking male officer agent of the secret criminal organization Baroque Works, second only to the group's leader, Sir Crocodile. Before joining Baroque Works, Daz Bones was a notorious and accomplished assassin in the West Blue, a reputation that preceded him. His cold, pragmatic, and highly disciplined personality reflects his background as a professional killer. He is utterly loyal to Crocodile, viewing him as a leader worth following without question, and he carries out his orders with brutal efficiency and minimal emotion. His motivations are tied directly to his role within Baroque Works: he is committed to executing Crocodile's plan to destabilize and take over the kingdom of Alabasta. In the story, Mr. 1 is stationed in the capital city of Alubarna to intercept the Straw Hat Pirates and prevent them from interfering with the organization's scheme. He serves as the primary obstacle for the pirate swordsman Roronoa Zoro. Their confrontation is a pivotal moment in the film, as Mr. 1's abilities force Zoro to grow beyond his current limits. Key relationships include his partnership with Miss Doublefinger, his fellow officer agent, with whom he coordinates operations. His most significant relationship is with his superior, Crocodile, whom he respects and follows without reservation. In terms of development, Mr. 1 does not undergo a personal change during the film; he remains a steadfast and unwavering opponent. His role is to challenge Zoro, and his defeat marks a crucial step in Zoro's journey. Notably, Mr. 1 is the first adversary that Zoro cannot cut with his ordinary swords, which pushes Zoro to achieve a breakthrough in his swordsmanship. After his defeat, Mr. 1 is captured by the Marines and imprisoned in Impel Down, and he later participates in the Paramount War at Marineford, still acting as an enforcer under Crocodile. His most notable ability comes from the Supa Supa no Mi, a Paramecia-type Devil Fruit that grants him the power to transform any part of his body into a sharp, durable steel blade. This makes him a fullbody bladed human, allowing him to use his limbs as swords, spears, and shields. His offensive techniques include Sparkle, where he turns his fingers into small blades; Spinning Blades, where he transforms his legs into large blades and spins to attack; and Atomic Spar, a devastating cross-slash that he claims can cut matter at an atomic level. He also has the defensive technique Spider, which makes his body completely immobile and as hard as steel, rendering him nearly invulnerable for a short time. The combination of his deadly precision, his body's blade-like hardness, and his vast experience as an assassin makes him one of the most formidable fighters within Baroque Works.
