Quick Answer
The 3 brothers of One Piece — Monkey D. Luffy, Portgas D. Ace and Sabo — are not biological brothers but sworn brothers. They sealed their brotherhood as children on Mt. Corvo (Goa Kingdom) by sharing cups of saké. Each embodies a distinct will of freedom: Luffy wants to become Pirate King, Ace wanted to prove he deserved to exist despite his father Roger, and Sabo stood against the aristocracy by joining the Revolutionary Army. Their bond is one of the most powerful emotional pillars of the entire series.

Who are the 3 brothers of One Piece?
| Brother | Biological father | Affiliation | Devil Fruit | Status |
|---|---|---|---|---|
| Monkey D. Luffy | Monkey D. Dragon | Straw Hat Pirates (Yonko) | Hito Hito Nika | Alive — 5th Yonko |
| Portgas D. Ace | Gol D. Roger | Whitebeard Pirates (2nd div. commander) | Mera Mera no Mi (Flame-Flame Fruit) | Deceased at Marineford |
| Sabo | Outlook III (Goa nobleman) | Revolutionary Army (No. 2) | Mera Mera no Mi (heir) | Alive |
These three characters have completely different origins but a shared childhood. It is one of the most memorable found family stories in modern manga.
The origin of the sworn brotherhood
The Mt. Corvo flashback arc (chapters 583–589, vol. 60) recounts the three brothers’ childhood. Key facts:
- Ace grew up at the Dadan family’s home, secretly raised by Garp to protect him from the Marines (he is Roger’s son, hunted to death).
- Sabo is a Goa nobleman’s runaway son, disgusted by aristocratic cruelty. He lives in the Gray Terminal with Ace.
- Luffy is entrusted to Dadan by Garp at age 7. He meets Ace and then Sabo.
- The three exchange cups of saké following the pirate ritual — an inviolable sworn brotherhood.
The oath: “No matter what happens, we are brothers. We will set sail when we turn 17 and become free pirates.”
Monkey D. Luffy — the youngest brother
Identity
Born in Foosha Village (East Blue), son of Monkey D. Dragon (leader of the Revolutionary Army), grandson of Monkey D. Garp (vice admiral, Marine hero). Entrusted to Dadan at age 7 to be “raised”. Met Red-Haired Shanks, who gave him his iconic straw hat.
Dream
To become Pirate King by finding the One Piece at Laugh Tale. Goal nearly within reach: 5th Yonko in 2026, the Straw Hats on Egghead, all Road Poneglyphs being tracked down.
Character
Joyful, instinctive, loyal to a fault. Always refuses authority but respects deep friendships. Eats a lot, sleeps anywhere. See the Luffy 3-billion poster.
Portgas D. Ace — the middle brother
Identity
Born in Baterilla (South Blue), biological son of Gol D. Roger and Portgas D. Rouge (who carried Ace for 20 months to conceal his birth and save him from the Marine hunt). Secretly raised by Garp. Refused the name Roger his entire life, taking his mother’s name instead.
Dream
To prove he deserved to exist despite his father Roger. To become a great pirate on his own terms, free of his father’s shadow. Captain of the Spade Pirates, then commander of the 2nd division of the Whitebeard Pirates by brotherly adoption.
Death
Died at Marineford (chapter 574, vol. 59) shielding Luffy from Akainu’s attack. His death is one of the most emotionally devastating moments in the manga, topping every fan ranking. His Mera Mera no Mi resurfaced in the Dressrosa Tournament, inherited by Sabo.
Sabo — the eldest brother
Identity
Born into Goa nobility, son of Outlook III. Fled his family at age 10, disgusted by the Noble System that mistreats commoners. Presumed dead for 12 years after a Celestial Dragon (Saint Jalmack) destroyed his childhood boat at sea. Saved by Dragon and secretly raised as No. 2 of the Revolutionary Army.
Dream
To destroy the aristocracy and liberate the oppressed. To recover his memories of his brothers (he suffered from amnesia for 12 years). To inherit the Mera Mera no Mi and carry on Ace’s will.
Current status
Alive. Number 2 of the Revolutionary Army, under Dragon. Participated in the Reverie. Struck directly against the Celestial Dragons and Im-sama. His exact bounty has not been revealed.
The sworn brotherhood: symbol and meaning
The saké cup ritual that Luffy, Ace and Sabo performed is directly inspired by traditional pirate oaths and Japanese yakuza ceremonies. It is a sacred and unbreakable act.
Why does this oath resonate so deeply with fans?
- Found family — no biological link, yet a bond stronger than blood
- Three opposing paths — pirate, revolutionary, hidden son — all converging on the same quest for freedom
- The final tragedy — Ace’s death turns the oath into an eternal wound for Luffy
- The inheritance — Sabo takes up the Mera Mera no Mi, keeping Ace’s flame alive
The 3 Brothers pack at Wanted Store
To honour this sworn brotherhood, Wanted Store offers the 3 Brothers pack: three posters uniting Luffy, Ace and Sabo. It is one of the most emotionally charged packs in the shop, perfect for:
- A dedicated bedroom or fan shrine wall
- A gift for a fan who understands the emotional depth
- A framed triptych above a sofa or desk
- A memorial to Ace (the One Piece community has its own equivalent of “Where were you when…” with his death)
Connection to the broader One Piece lore
The 3 brothers embody the three great paths of rebellion against the World Government:
- Luffy → Pirates (rebellion through individual freedom)
- Sabo → Revolutionaries (organised political rebellion)
- Ace → Whitebeard Pirates (rebellion through crew brotherhood)
This narrative structure reflects Oda’s central thesis: freedom can take many forms, but it always requires a fight against the established order.
FAQ — The 3 Brothers: Luffy, Ace, Sabo
Are Luffy, Ace and Sabo really brothers?
No — not biologically. They are sworn brothers. They exchanged cups of saké on Mt. Corvo in their childhood, sealing a sacred brotherly bond in the Japanese pirate tradition.
Who is each one’s biological father?
Luffy: Monkey D. Dragon (revolutionary). Ace: Gol D. Roger (Pirate King). Sabo: Outlook III (Goa nobleman). Three figures at ideological opposite poles.
How did Ace die?
At Marineford (chapter 574, vol. 59), shielding Luffy from Akainu’s magma attack. Akainu was targeting Luffy with a magma fist; Ace stepped in and was impaled. He died in Luffy’s arms after passing on his final words of gratitude.
Is Sabo also dead?
No. Sabo was presumed dead for 12 years after his boat was destroyed by a Celestial Dragon. In reality, he was saved by Dragon, lost his memory, and was raised as No. 2 of the Revolutionary Army. He recovered his memories upon learning of Ace’s death.
Why did Sabo inherit the Mera Mera no Mi?
To carry on Ace’s will and symbolise that his brother’s flames continue to burn. Sabo won the fruit at the Dressrosa Tournament against Burgess (Blackbeard Pirates). It is a deeply emotional act: Sabo now fights with the power of his fallen brother.
Is there a 3 Brothers poster pack?
Yes — Wanted Store offers the 3 Brothers pack with the Wanted Posters of Luffy, Ace and Sabo. It is one of the most beloved packs among fans for its emotional depth.
Why is the 3 Brothers arc so important?
Because it shapes Luffy’s entire psychology and explains his absolute loyalty to his friends. His fury at Marineford, his later awakening, and his quest to become Pirate King are all rooted in this sworn oath and the loss of Ace.
Will Luffy and Sabo reunite?
Yes — this is one of the most anticipated emotional arcs of the series’ endgame. Sabo already reunited with Luffy at Dressrosa, but a “fully conscious” reunion with a proper tribute to Ace is something fans eagerly await.
