Background / History

Ace was born on Baterilla Island to Gol D. Roger and Portgas D. Rouge. To conceal Roger’s son from the World Government, Rouge delayed Ace’s birth until one year and three months after Roger’s death; she died from exhaustion immediately after giving birth. Ace inherited her surname rather than Roger’s. 61 62 251

He is Haku’s blood relative through Rouge, who was Haku’s paternal aunt. Haku considers Ace the only blood relative he has left in the world and acts to protect him despite serving as a Marine Admiral. 26 61 62

Ace sought to prove the value of his existence, telling his brothers that he wanted his name to shake the world and earn acknowledgment. Haku anticipated that this drive would eventually lead Ace to challenge Whitebeard. 62

After setting sail, Ace became captain of the Spade Pirates before the crew was integrated into the Whitebeard Pirates. He subsequently became their Second Division Commander. 104

Personality

Ace is resolute and strongly motivated by loyalty. He pursues Blackbeard alone to avenge a murdered crewmate and uphold the Whitebeard Pirates’ honor, even after being warned that Teach is exceptionally dangerous. 156

His pride can make him reckless. During the Summit War, Akainu’s insults toward Whitebeard provoke Ace into abandoning his escape and confronting the Admiral. 260

Following Whitebeard’s death, Ace initially doubts his ability to lead the crew and blames himself for past losses. With support from Haku and Marco, he accepts the responsibility of becoming captain and carrying on Whitebeard’s will. 289

Abilities & Skills

Flame-Flame Fruit

Ace’s Logia-type Devil Fruit grants him control over fire, forming the basis of his “Fire Fist” fighting style.

• Can coat his body in flames and launch powerful fire-based attacks. 155 260
• His flames become more concentrated through Ryujin Jakka’s training, progressing from yellow-orange to gold and eventually bluish-white. 442 444
• His fire attacks can disperse King’s Fire Dragon King technique. 444
• Previously relied too heavily on his Devil Fruit rather than developing his broader combat ability. 290

Tremor-Tremor Fruit

Haku gives Ace the Tremor-Tremor Fruit formerly wielded by Whitebeard after modifying it to coexist with another Devil Fruit. 289 290

• Produces white vibration waves capable of generating destructive shockwaves. 289 443
• Can use vibrations defensively, precisely canceling or redirecting King’s fire attacks away from allies. 444
• Its return to the Whitebeard Pirates reinforces Ace’s claim as Whitebeard’s successor. 289

Dual Devil Fruit Combat

Ace can wield the Flame-Flame and Tremor-Tremor Fruits at the same time without suffering a conflict between their powers. 289 444

• Combines blazing strikes with vibration waves in close combat. 444
• The dual abilities elevate him into the ranks of top-tier combatants and alarm King. 444
• His power remains dependent on continued training; Haku warns that Devil Fruits alone cannot make him a top fighter. 290

Haki

Ace possesses the potential for Conqueror’s Haki due to his lineage and disposition, but had not awakened it when Haku began training him. 290

• Has not yet awakened Conqueror’s Haki at the time Haku confronts him. 290
• Needs to further develop his Armament Haki to compete with fighters such as Kaido. 290

Relationships

• Portgas D. Haku — Biological cousin through Portgas D. Rouge, though they address one another as brothers. Haku arranges protection for Ace, helps engineer his escape from execution, gives him the Tremor-Tremor Fruit, and pushes him to become stronger. 26 62 289 443
• Gol D. Roger — Biological father. Ace rejects Roger as his father and instead recognizes Whitebeard in that role. 251
• Portgas D. Rouge — Biological mother. She concealed Ace’s parentage by delaying his birth and died after delivering him. 62 251
• Edward Newgate / Whitebeard — Adoptive father and captain. Whitebeard accepts Ace despite Roger’s legacy and entrusts the future of his crew to him. 62 289
• Marco — Senior crewmate and supporter. Marco protects Ace during the Summit War and later encourages him to accept the captaincy. 260 289
• Monkey D. Luffy — Sworn brother. Luffy invades Impel Down and Marineford to rescue Ace, ultimately reaching the execution platform. 238 259
• Sabo — Sworn brother. Returns during the Summit War to protect Ace and Luffy from Akainu. 260 261
• Marshall D. Teach / Blackbeard — Former comrade turned enemy. Teach murders a crewmate, steals the Dark-Dark Fruit, and defects; Ace pursues him to answer for the betrayal. 156
• Ryujin Jakka — Haku’s Zanpakuto spirit and fire-using counterpart. Initially clashes with Ace on Drum Island, later trains him to refine his flames. 155 442
