Power Progression

Stage / Realm / Level	Chapter	Notes
Basic Observation Haki — first documented	22	His Observation Haki is comparable to Trebol’s relatively undeveloped ability. Dividing his attention between swordsmanship and Devil Fruit development limits his progress.
Dual-Haki combat — demonstrated	45	Detects Gray’s attack from behind with Observation Haki and counters with an Armament-coated sword.
Marine Headquarters Rear Admiral equivalent	66	Explicitly assessed at this level alongside Pica before the family departs for the New World.
Pure-swordsmanship adjustment	69	Recognizes that his poorly integrated fruit powers are hindering him against Kyros and temporarily abandons them, making the duel more evenly matched.
High-level master swordsman; elite Vice Admiral threshold	89	Following his defeats and pressure from Gray’s growth, commits to swordsmanship rather than fruit-and-sword integration. His improved blade work and competent dual Haki bring him barely to elite Vice Admiral level. He also demonstrates Shave and Geppo in combat.

Personality

Diamante is proud of his swordsmanship and quick to declare that he will win. That confidence frequently becomes overconfidence: he underestimates Kyros’s experience and later assumes that Tesoro’s Golden Giant can be cut apart like Pica’s Stone Giant 68 69 89.

His pride also makes self-correction painful. Although he recognizes the incompatibility between his swordplay and his use of the Flap-Flap Fruit, he initially resists admitting his limitations. Gray’s rapid growth threatens his standing among the family’s strongest fighters, eventually motivating him to specialize rather than continue developing two disciplines unsuccessfully 69 89.

As an instructor, Diamante responds readily when recruits seek help. His methods can be harsh—he strikes Gray to improve his concentration during meditation—but he continues supporting Gray through regular sparring. He also joins the family’s celebrations, offering Gray rum after the development of his flight ability 6 7 9 45.

Despite his bluster, Diamante can recognize danger and withdraw. Against Tesoro, he detects airborne gold dust, retreats before inhaling it, and later obeys Doflamingo’s order to leave the fight without arguing 89.

Abilities & Skills

Swordsmanship

Diamante combines close-range swordplay, flying slashes, and Haki reinforcement. His strongest documented improvement follows his decision to concentrate on the sword rather than force a hybrid fighting style 68 69 89.

• Half-Moon Funeral: A crescent-shaped flying slash that cuts through an entire incoming cannonball barrage. It is described as the pinnacle of his swordsmanship during the confrontation with Tesoro 68 89.
• Precision defense: Tracks and cuts Tesoro’s golden whips while advancing, dodging most attacks and severing those aimed at his blind spots 89.
• Combat-experience limitation: Kyros exploits his lack of experience against equally strong opponents, baiting him into a committed attack that he cannot safely withdraw 69 70.
• Cutting-power limitation: Even a full-strength, Haki-coated strike only penetrates partway into Tesoro’s awakened Golden Giant’s palm 89.

Flap-Flap Fruit

Diamante initially incorporates his Devil Fruit into a style called Fluttering Swordsmanship, but cannot integrate the two disciplines smoothly 69 89.

• Against Kyros, the hybrid style leaves him less effective than straightforward swordsmanship and Haki would have been 69.
• After the Kyros defeat and Kaido’s assault, he abandons attempts to merge the fruit with his swordplay and focuses on his blade instead 89.

Haki

Diamante uses both Observation and Armament Haki, eventually developing enough proficiency for them to support his high-level swordsmanship 45 89.

• Observation Haki: Detects Gray’s surprise attack, assesses Kyros’s aura, tracks golden whips, and notices otherwise invisible gold dust 45 68 89.
• Armament Haki: Coats his sword to clash with Gray’s hardened fist and strengthen attacks against Tesoro’s defenses 45 89.
• Endurance limit: His Observation Haki becomes depleted during an extended sparring session with Gray 46.
• Perception limit: His Observation Haki cannot decisively overcome Pica’s ability to move within stone, leaving their sparring matches without a clear winner 89.

Movement and Physical Conditioning

• Shave: Uses consecutive bursts of high-speed movement to escape the Golden Giant’s descending fist 89.
• Geppo: Moves through the air during combat and returns to Doflamingo’s ship after being recalled 89.
• Breath control: His conditioning allows him to plan on fighting without breathing for two or three hours to avoid Tesoro’s gold dust 89.

Instruction

• Teaches meditation and concentration to the family’s recruits, including Gray 6 7.
• Serves as Gray’s regular martial-arts and swordsmanship sparring partner, adjusting his defense to account for Gray’s spatial movement 45 46.

Equipment

• Sword: Carried at his waist; used for flying slashes and Armament-coated close combat 45 68.
• Cape: Worn during his confrontation with Tesoro’s Golden Giant 89.

History

North Blue and Gray’s Training

Diamante is already a Donquixote Family executive when Gray suffers his near-fatal injury. He attends the meeting where Doflamingo reprimands Corazon and arranges compensation for Gray 1.

When Gray begins developing his powers, Diamante teaches him meditation. Their training relationship continues as Gray becomes stronger, culminating in a sparring session where Gray reveals his newly awakened Armament Haki 6 7 45.

Diamante also accompanies Gray, Baby-5, and Shark Chili to the family’s secret weapons workshop near the Calm Belt, guiding them to the craftsmen preparing Gray’s custom weapon 48.

Battles with the Marines and World Government

During Tsuru’s approach, Diamante stands immediately to Doflamingo’s left, opposite Pica—a formation explicitly marking their status. He is selected to help delay the Marines while the remaining family members prepare to abandon the base 23.

He later attacks CP9 personnel during the Heavenly Tribute operation, killing many and injuring others. When Aokiji arrives in response to the robbery, Doflamingo again selects Diamante, alongside Gray and Pica, to remain behind and cover the retreat 52 57.

Defeat at Dressrosa

Upon reaching Dressrosa, Diamante destroys the Royal Army’s incoming cannonballs and volunteers to fight Kyros. Doflamingo approves, treating the duel as an opportunity for his growth 68.

Kyros’s direct, efficient swordsmanship exposes the weaknesses in Diamante’s fruit-assisted style. Switching to pure swordplay improves Diamante’s performance, but Kyros ultimately deceives him with an opening. Diamante suffers a forehead wound deep enough to expose his skull and a fractured sternum; Gray intervenes to save him, and Pica takes over the fight. Diamante responds by vowing to train harder 69 70.

Kaido and the Beasts Pirates Partnership

During Kaido’s assault, Diamante is struck and sent flying alongside Gray and Pica. This experience, together with his defeat by Kyros, contributes to his later decision to abandon his hybrid fighting style 76 89.

After Dressrosa’s reconstruction, he accompanies Doflamingo, Gray, and Viola toward Wano. On the voyage, his Half-Moon Funeral is countered by the Wright Brothers Pirates, and he initially claims their captain as his opponent. He subsequently attends the meeting with Kaido on Onigashima 79 82.

Confrontation with Tesoro

Diamante and Pica accompany Doflamingo to the North Blue to confront Tesoro, who stole the family’s Gild-Gild Fruit. Diamante volunteers to defeat him and seize his gold for the family 89.

His improved swordsmanship allows him to cut through Tesoro’s golden whips, but the awakened Golden Giant stops his strongest attack. After escaping with Shave, he withdraws on Doflamingo’s orders. He and Pica assist in the ensuing pursuit, though Tesoro escapes underwater 89 90.

The expedition returns to Dressrosa after three months, with Doflamingo announcing a partnership with Tesoro. Diamante is later seen beside Pica after Gray visits Doflamingo to arrange potion sales 92 111.

Relationships

• Doflamingo — Captain and leader. Diamante fights to keep pace with him, follows his orders, and receives his backing even when defeat is possible 23 69 89.
• Gray — Student, sparring partner, and source of competitive pressure. Diamante helps train him, while Gray’s rapid improvement ultimately pushes Diamante to reassess his own fighting style 6 45 89.
• Pica — Fellow principal lieutenant and sparring partner. Their abilities make a decisive sparring victory difficult for either, and they frequently accompany Doflamingo together 23 89 90.
• Kyros — Opponent whose technical discipline and experience expose Diamante’s weaknesses. His defeat of Diamante becomes a major catalyst for change 69 70 89.
• Gild Tesoro — Enemy during the North Blue expedition. His awakened gold defenses defeat Diamante’s attempts to cut through them; Doflamingo later establishes a partnership with him 89 92.
