One of the best stories in One Piece is that of Luffy, Sabo, and Portgas D. Ace. It's also one of the saddest stories in the series. The friendship and bond that formed between the three "brothers" became true over the years, and with its tragic ending, a beautiful story actually came to a very dark end. But, putting that aside for now, in this article, we're actually going to tell you a little bit about Luffy and whether the three of them are biological brothers, or if their "brotherhood" was just a distinction that has nothing to do with their family. In this article, in short, you're going to find out how many brothers Monkey D. Luffy has.

Biologically, Monkey D. Luffy has no siblings. As far as is known, he is an only child, with no brothers or sisters. However, due to his close friendship with Sabo and Ace, as well as the pact they made as children, the three of them could be considered "brothers," but not biological brothers. This would mean that Luffy has two brothers, but they are symbolic, not biological.

The rest of this article will explore Luffy's relationship with Ace and Sabo, focusing on the nature of their relationship and the symbolic value of their friendship. If you're not fully up to date with the events of One Piece, this article may contain significant spoilers, but we must point out that no new information will be presented here, as we'll be focusing on old, well-known facts about the three of them.

Luffy has no biological siblings, but Sabo and Ace can be considered his "brothers."

The relationship between Luffy, Sabo, and Ace is one of the most important in the entire series, so we're here to tell you everything you need to know. When Luffy was entrusted to Dadan by his grandfather, Garp, Sabo and Ace were already best friends and had amassed a greater treasure through minor and major thefts when Luffy spotted them near the Gray Terminal.

The two men kidnapped the young man and tied him to a tree to kill him, as he seemed to be hindering their plan to become wealthy pirates. But since neither of them had ever done anything like this before, it proved more difficult than expected.

They also learned about Polchemy, a member of the Bluejam pirate gang who was Ace's last victim. The two seek safety, but Luffy is discovered and taken hostage by the pirates because he lies about not knowing Ace or Sabo.

Sabo discovered that Luffy had been tormented by Polchemy but didn't reveal anything until the two panicked and moved their loot to a new hiding place. Ace and Sabo were inspired by Luffy's courage and loyalty, so they broke into Polchemy's hideout, freed Luffy, and together destroyed Polchemy. Bluejam then shot Polchemy dead because he had lost the money Ace had stolen from him and lost it to two children.

The three of them immediately realized that Sabo was no longer safe in the gray terminal, so he also checked in with Dadan. They hunted together as a group, cooked decent meals, and prepared for the next time. Luffy continued to challenge them but was defeated each time.

All three also traveled to the capital of the kingdom of Goa, where they met many petty criminals and dined at a few restaurants in the city before cheating on the bill.

However, they unexpectedly run into the street with Sabo's father, who recognized his son even though he had been missing for years. The two companions later joined him in the forest of Colubo Mountain, and he admitted to having deceived them, as he was actually an aristocrat who had run away from his family rather than an orphan like the two of them.

Sabo revealed to Ace and Luffy his dream: to travel the world and publish a book about it, while they showed no interest. After hearing the other two recount their hopes, the three then toasted their brotherhood. Over the next few weeks, the three men made the region dangerous while supporting each other as much as possible. They were welcomed into the village of Foosha by the young and handsome Makino, who was highly regarded by the mountain bandits.

Meanwhile, Garp also returned from the snow to give them three spankings. A note stating that Ace, Sabo, and Luffy had left and were now living in a jungle shelter was finally discovered by Dadan after some searching.

Their life together was abruptly interrupted when Sabo's father went looking for him with the Bluejam Pirates and threatened to kill Ace and Luffy so that his son would no longer need a reason to survive in the wild. Sabo therefore abandoned his aspirations and agreed to return voluntarily if his father spared his comrades in order to protect his friends.

Back in town, Sabo sought to prevent Ace and Luffy from being blamed for his kidnapping, but he was powerless against the corrupt system where Sabo's father had no trouble pursuing his interests with a pile of dollars to pay for the berries. When Sabo returned home, he discovered that his parents had adopted his younger brother, Sterry, as their heir following the loss of their eldest son.

He eventually discovered that the aristocracy intended to burn down the Gray Terminal, along with all its trash and people, to create a pristine cityscape for the Celestial Dragons, their next guest. Despite his best efforts, Sabo was unable to save the residents of Gray Terminal due to the city's military. When Sabo encountered Dragon on the city streets, he told him he was fed up with the appalling and inhumane conditions there. Dragon, who was wearing a cape, was shocked by Sabo's comments.

Sabo later enlisted in the Revolutionary Army under the command of Luffy's father. Ace joined Whitebeard's Pirates and died while defending Luffy against Akainu. As we all know, Luffy embarked on his own journey to become the Pirate King. Sabo and Luffy would cross paths again later, but Ace's untimely death remains one of the most heartbreaking events in One Piece's narrative.

And because Sabo and Ace had a deep understanding of Luffy, they were taken into account when creating the scene. They are important individuals in his life, and Oda wanted this scenario to emphasize that.

As you can see, the relationship between the three of them was quite close, and they were best friends. Knowing what pacts mean to pirates, it's obvious that the fact that the three of them made one actually meant that they considered each other brothers, regardless of their actual family. This is why this topic is so important from Luffy's perspective, and why this pact, and these three children, are still one of the most important elements of One Piece's story.

Sabo and Ace both come from completely different families than Luffy.

Before we end this article, we just want to tell you about the families of Luffy, Sabo, and Ace so that you have no doubt that they are not Luffy's biological brothers.

Ace was born on Baterilla Island in the South Blue 15 months after the death of his father, Gol D. Roger. His mother, Portgas D. Rouge, gave birth to him after a 20-month pregnancy to save him from the World Government and the Navy, who were searching for Roger's possible child to execute him.

His mother named him "Gol D. Ace" and died of exhaustion. He took his mother's name in honor of her sacrifice. Garp, having witnessed his birth, took him with him and cared for him, as he had promised Roger 15 months earlier.

Luffy's biological father is Monkey D. Dragon, the leader of the Revolutionary Army, who was never present in Luffy's life and left his son in the care of his own father, Luffy's grandfather, Monkey D. Garp, despite following his exploits throughout the series.

The identity of Luffy's biological mother is still unknown; his adoptive mother was Curly Dadan. According to Oda himself, Luffy's mother will likely never be introduced.

Sabo was born in the Kingdom of Goa. He was born into a noble family whose parents wanted him to marry a royal girl to elevate their own status, regardless of his opinion on the matter. Aware of this, Sabo ran away around the age of five, presumed dead by his parents. He then met Ace, with whom he began stealing around the city and at the Grey Terminal, becoming best friends.
