Power Progression

Background / History

Early Life and the Four Suits

Diamante’s childhood memories involve his mother’s illness and a lasting sense of shame. These experiences remain tied to the flamboyant persona he builds and his later belief that he does not deserve the resources the Family spends on him 328.

At fifteen, he belongs to the Four Suits alongside Trebol, Pica, and Vergo. Before becoming seafarers, the group operates as local toughs around Spandamruze. Diamante and Trebol are particularly close, having endured harassment from nobles, provocations from thugs, and hostility from constables together 16 32 129.

Joining the Donquixote Family

Rossi and Doflamingo help the wounded officers escape the Jedi Family. Diamante assists in freeing Trebol and later carries him during their retreat. After witnessing Doflamingo’s Conqueror’s Haki, he kneels and identifies it as the aptitude of a king chosen by fate; Rossi interrupts the officers’ attempted oath of service 22 23.

Diamante initially treats Doflamingo’s exceptional power as assurance of their future victory. Their subsequent travels instead expose him to repeated battles and demanding training. When Rossi chooses to defend Odense, Diamante stays with the others without demanding an explanation and urges him to present the plan 25 43 48.

Swordsmanship and the Search for Strength

Diamante’s confidence is repeatedly tested by the Family’s rapid development. Pica defeats him decisively in unarmed training, while Rossi and Doflamingo advance beyond what he can comfortably follow. He nevertheless masters water-treading and fulfills his promise to learn Cutting Steel in three days 70 71 75 93.

As a Family officer, he kills the provocateur Vulture with one sword strike on Beast Fighting Island. Against stronger enemies, however, his limitations become apparent: Babadosa’s Haki-coated hair traps his sword and withstands much of his strongest Flying Slash 110 125.

After the conflict with Gamenio, a badly injured Diamante asks for the Gold-Gold Fruit. He abandons his usual ritual of polite refusals, explaining that he cannot bear to let Doflamingo and Rossi suffer such humiliation again. Both support his request, and he eats the fruit 147.

Doubts About His Place

Diamante develops a pragmatic fighting style built around gold weapons, armor, and concealed attacks. When a Cipher Pol Aigis Zero agent questions his identity as a swordsman, he openly states that protecting the Family matters more to him than respecting the sword 160 163 164.

His insecurities persist. Although he ultimately kills the Deathwind Pirates’ Bubble-Bubble Fruit user, Jinbe must first save him from the ability’s weakening effects. Diamante later asks Rossi whether he is qualified to remain an officer. Rossi reassures him that unpredictable, rule-based abilities could also endanger the brothers 221 224.

The Golden City

Rossi takes Diamante, Oni, and Gary on an expedition to Shandora. By this point, Diamante sees himself as inferior to companions with clearer specialties: Rossi surpasses his swordsmanship, Doflamingo surpasses his Devil Fruit mastery, and his own gold consumption places a heavy burden on the Family’s resources 322 328.

At the city’s golden spire, Rossi’s encouragement finally breaks through his shame. Remembering the support of the entire Family, Diamante accepts his place among them and absorbs the city’s gold. He becomes a towering black-and-gold colossus, splits the clouds with an enormous sword, and promises to crush any enemy Rossi names 328.

Later Service

Diamante remains involved in the Family’s life beyond battle. He prepares a gift for Scarlet and Kyros’s child, offers to teach Rebecca swordsmanship, and enthusiastically agrees to attend Pica’s wedding 334 350 389.

During the brothers’ absence, he continues fighting alongside the Family and eventually reaches Yonko Commander-level strength. When Doflamingo returns, Diamante embraces him and says that his return is enough, then helps explain the years that have passed for those left behind 461 467.

Appearance

Diamante is exceptionally tall and thin, with a five-meter-tall body documented during his fight with Xu Quan 22 342.

• Flamboyant clothing: His exaggerated outfits stand out even at formal gatherings 70.
• Metal ornaments: His accessories jingle when he laughs 68.
• Amber-tinted glasses: Worn during the return voyage from the Golden City expedition 334.
• Concealed golden armor: Fitted beneath his suit and revealed when an enemy tears through the fabric 163.
• Elaborate golden helmet: Temporarily covers his swollen face after sparring with Kyros 229.

Personality

Diamante combines theatrical modesty with a strong desire for recognition. He habitually refuses praise or gifts until others insist, then accepts with enthusiasm. The Family knows this “refusal and entreaty” routine well enough to treat it as an unwritten rule 42 93 328.

His boasting conceals genuine insecurity. He worries about losing his standing as the Family’s leading swordsman, compares himself unfavorably with more gifted companions, and is deeply troubled when others must rescue him. These doubts culminate in his question about whether he deserves to remain an officer 75 129 224 328.

His loyalty ultimately outweighs professional pride. Diamante does not reject Devil Fruit-assisted swordsmanship as illegitimate, and he freely admits that victory and the Family matter more than the sword itself. His determination to become stronger is driven less by an abstract title than by his refusal to see his companions humiliated or endangered 93 147 164.

He also enjoys drinking, flirtation, mockery, and gossip. He seeks strong liquor after exhausting voyages, returns from the arena with women on both arms, and teases Kyros over the timing of Scarlet’s pregnancy 43 111 334.

Abilities & Skills

Swordsmanship

Diamante exploits exceptional reach, broad cutting arcs, and rapid changes between long and short blades. Doflamingo identifies him as the Family member best suited to quickly master Cutting Steel, though Diamante acknowledges Rossi’s earlier breakthrough 30 93.

• Arc Light: A descending slash that severs rigging and brings down several boarding pirates 42.
• Half Moon: Sweep: Sweeps aside more than a dozen spears and throws their wielders backward 64.
• Half Moon: Windmill: Creates a spinning vortex of sword strikes that breaks weapons and splits armor 64.
• Burial / Half Moon: Burial: An emerald Flying Slash used against Sea Monkeys and Babadosa’s hair 110 125.
• Half Moon Funeral: A rapid thrust used when emerging from the fragments of a giant broken sword 342.
• Concealed short blade: Allows him to continue attacking after an opponent closes inside his reach or immobilizes his larger weapon 163 342.
• Limit: His long weapons become cumbersome when a sufficiently fast opponent penetrates their defensive range 163.

Gold-Gold Fruit

Diamante controls and reshapes existing gold into weapons, protection, and large structures. The fruit does not create gold from nothing or turn its user into gold; its potential depends heavily on the available supply 240 328 329.

• Golden Blade: Sends gold flowing from his sleeve and shapes it into a rigid sword 160.
• Golden armor: Protects his body beneath his clothing, although powerful Haki-coated strikes can dent and crack it 163.
• Golden Splash: Conceals extremely fine powder among scattered gold flecks, causing a masked agent to cough blood after repeated exchanges 164.
• Golden constructs: Produces spears and mobile gold defenses independently of his held weapon 165.
• Golden colossus: Uses Shandora’s reserves to form a giant body covered in Armament Haki, wielding a sword large enough to split clouds 328.
• Gold-Gold: King’s City Reappearance: Reshapes the colossus into an ornate golden castle resembling Dressrosa’s Royal Plateau 329.
• Limit: His fine gold powder can be swept away by powerful area-wide vibrations 265.

Armament Haki

Diamante reinforces his gold weapons with Haki and can contend directly with Haki-coated attacks from Cipher Pol Aigis Zero agents and the Deathwind Pirates’ red-robed fighter 160 221.

• Coats the Golden Sword to meet a heavy warhammer head-on 221.
• Covers his enormous golden creation in pitch-black Armament after the Shandora breakthrough 328.
• Remains vulnerable to sufficiently powerful rule-based abilities; the Bubble-Bubble Fruit weakens him despite his combat experience and Haki 221.

Movement and Impact Control

Diamante learns techniques that support fighting at sea and absorbing heavy blows 75 221.

• Water-treading: Runs over the sea after sustained training; his earliest successful version is comparatively slow and vulnerable to gunfire 75 77.
• Force dispersal: Channels an incoming impact through his feet into the ground or deck, cracking the surface while stabilizing himself 221.
• Underwater limitation: As a Devil Fruit user, he is vulnerable to seawater. Rossi proposes sealed golden diving armor with an air supply, but its completed deployment is not shown in the cited discussion 208.

Equipment / Weapons / Items

• Long rapier: An early weapon exceeding two meters in length, suited to controlling large areas of a ship’s deck 30.
• Replacement longsword: Acquired after earlier battles leave him using a broken weapon 128 132.
• Golden swords and greatswords: Reshaped through the Gold-Gold Fruit and reinforced with Haki 160 163 221.
• Hidden short blades: Incorporated into larger weapons for surprise attacks 163 342.
• Golden armor and helmet: Used for protection and, on one occasion, to conceal injuries from sparring 163 229.

Relationships

• Rossi — Rescuer, instructor, and the companion who most directly confronts his insecurities. Teaches him combat principles, reassures him of his value, and brings him to the gold that enables his greatest breakthrough 22 93 221 224 328.
• Doflamingo — Leader whom he initially reveres as a destined king. Encourages his swordsmanship, approves his request for the Gold-Gold Fruit, and receives an emotional embrace upon returning to the Family 23 93 147 461.
• Trebol — His closest friend within the Family, bound to him by their difficult early years. Their affection coexists with teasing and competitive sparring 70 129 229.
• Pica — Longtime companion who decisively outclasses him in unarmed combat. Diamante later promises to attend his wedding 70 71 389.
• Vergo — Fellow officer frequently paired with him for frontline duties and responsibility for Dressrosa 170 224.
• Jinbe — Saves him from the Bubble-Bubble Fruit user and creates the opportunity for him to resume the fight 221 224.
• Kyros — Sparring rival whose sudden mastery of Armament Haki leaves Diamante injured and frustrated 229.
• Rebecca — Recipient of his offer to provide swordsmanship training 350.
