Mr. 1 (Daz Bones)
Daz Bones, widely known by his codename Mr. 1, is a fictional character in the manga and anime series One Piece created by Eiichiro Oda. He appears as a high-ranking operative of the criminal organization Baroque Works and functions principally as an assassin and bodyguard. Mr. 1 is notable for his role as an antagonist in the Alabasta Arc and for his distinctive combat ability that allows him to transform parts of his body into steel-like material, making him one of the more physically durable opponents faced by the protagonist Monkey D. Luffy.
Daz Bones is introduced as agent number 1 of the covert organization Baroque Works, which is led by the warlord-turned-smuggler Crocodile (under the alias Mr. 0). Baroque Works operated with a hierarchical codename system that paired numbered agents with female partners whose names used week-day motifs (e.g., Miss All Sunday). Prior to his Baroque Works tenure, Bones' detailed early life is sparingly documented in the primary narrative; supplemental databooks provide limited contextual descriptors of his personality as a cold, efficient killer. After the defeat of Baroque Works during the Alabasta Arc, Bones' subsequent whereabouts are briefly suggested through later chapters and databook hints that he survives major conflicts and may reappear in the wider power shifts of the New World era.
Mr. 1's principal ability is the capacity to render parts of his body into a hard, blade-like material that functions similarly to steel; this is presented in-universe as the awakening of a Devil Fruit power, enabling him to transform tissues into metal. This power grants him exceptional offensive and defensive utility: he can form edged weapons from his limbs, resist standard edged attacks, and concentrate force for powerful strikes. During his battle with Roronoa Zoro, Mr. 1's steel body forces Zoro to evolve his own techniques, ultimately developing the ability to cut through steel with his swords. The confrontation between Mr. 1 and Zoro is often analyzed for its demonstration of matchup dynamics between Haki-adjacent concepts and Devil Fruit transformations prior to the full exposition of Busoshoku Haki.
Beyond his Devil Fruit-based transformation, Mr. 1 exhibits high endurance, precision in assassination techniques, and tactical discipline consistent with elite operatives in One Piece such as members of Cipher Pol or other clandestine groups. He wields blades and uses close-quarters combat, favoring surgical strikes over brute force.
Mr. 1's most significant role occurs in the Alabasta Arc, where he serves as one of the primary antagonists opposing the Straw Hat Pirates and their allies during the civil conflict in the kingdom of Alabasta. Paired initially with Miss Doublefinger and later operating independently, Bones participates in pivotal confrontations, most notably his duel with the Straw Hat swordsman Roronoa Zoro in the royal city of Alubarna. This duel culminates in Zoro acquiring a new edge in sword technique that allows him to cleave Mr. 1's metal form. Mr. 1 also appears in various flashbacks and databook entries that expand on Baroque Works' structure and missions. In animated adaptations produced by Toei Animation, his battles are depicted with extended choreography and soundtrack cues that underscore his menace.
Although his role diminishes after Baroque Works' collapse, Mr. 1 is referenced in narrative time skips and supplemental materials that situate former Baroque operatives within the shifting geopolitical landscape involving groups like the Revolutionary Army, the World Government, and other pirate crews. Canonical reappearances are limited, but his legacy in shaping Zoro's development remains a recurring motif in later arcs such as the Sabaody Archipelago and prelude to the Marineford confrontation through legacy effects.
Within Baroque Works, Daz Bones answers to Crocodile and interacts professionally with fellow agents including Miss All Sunday (Nico Robin in disguise), Miss Doublefinger, and other numbered operatives. His relationship with his superiors is utilitarian and hierarchical, reflecting the organization's clandestine and mission-oriented culture. His antagonistic interaction with Roronoa Zoro is the most developed character-to-character conflict in the series: their duel acts as both a personal rivalry and a catalytic training event that propels Zoro's growth. Through combat, both men demonstrate contrasting philosophies of strength—Bones as a precise killer, Zoro as an aspiring swordsman with a code of honor.
Mr. 1's connections outside Baroque Works are less elaborated; after the organization's downfall, he is effectively an isolated figure. Secondary materials and fan discourse sometimes speculate on potential alignments with other clandestine entities such as Cipher Pol or the Revolutionary Army, but canonical confirmation is limited.
Mr. 1 is frequently cited in critical and fan analyses as a memorable mid-series antagonist who contributed significantly to the development of Roronoa Zoro and to the thematic escalation of threat levels in One Piece. Critics praise the Alabasta confrontation for its pacing and for introducing a durable combatant whose power forced adaptive progression in a principal character. Merchandise, fan art, and cosplay often feature Mr. 1 due to his distinctive visual design and steel-transformation motif. Scholarly and fan commentary on power systems in One Piece commonly reference the Mr. 1 vs. Zoro bout as an early exemplar of encounter-driven evolution in combat technique, alongside later formalizations such as Haki and the varied classifications of Devil Fruit powers.
