Sabo

Sabo is a 10 year old boy who was born in a noble family but lives in Gray Terminal and was a friend of Ace during their childhood. He and Ace were secretly saving money to buy a pirate ship together.

Appearance
He was a ten year old boy at the time of Luffy's flashback, the same age as Ace. He has a chipped tooth and he wears a large top hat with a pair of goggles around it as well as a jacket and a scarf.

Personality
Not much is known about Sabo's personality at this time. He seems to be protective of his dreams and goals as he agreed with Ace that the two of them had to kill Luffy so that he couldn't tell anyone about their treasure, though neither Ace nor Sabo "knew" how to kill a person nor had experience implying some degree of innocence despite the profession. After Dadan says that she heard he's "quite a shitty little pipsqueak," he replies with a smile that he heard she's "quite a shitty old bag."

Like all of Luffy's friend's he is extremely loyal his nakama or in this case his two "brothers" as he would give into the demands of his father, becoming miserable and "alone" in order to save both Luffy and Ace.

Abilities and Powers
Sabo seems to have some level of fighting ability and speed, since he and Ace together were able to topple Porchemy when the two of them arrived to save Luffy. He also was fast enough to grab a knife from a pirate without the pirate being able to stop him. He appears to have good thieving skills as well, since he was able to rob so many people to get their money and valuables.

Also, it was revealed that he was able to beat Luffy 50 times in one day, as well as defeat Ace 24 and lose 26 times. According to Ace, he thought Sabo would become his navigator, suggesting that Sabo has some experience in navigation.

History
If it weren't for the Sabo incident and a troublesome brother like you, I probably would not have wanted to live....

Sabo's name is first mentioned by Ace during his final words at Marineford. However, he makes his appearance nine chapters later in a flashback of three months after Luffy and Ace met for the first time.

Having to be born in Goa to Noble parents, his father wanted him to marry a princess to keep his family name secured but Sabo refuse. Later Sabo was drawing a picture, his father came home tired from work and torn up the picture and order him to go to his room and study, making Sabo sad. One day he got in fight with a royal person in self-defense, however his mother ends up going to the royal person to ask if he's alright, leaving Sabo hurt. Feeling no love from his parents, he had enough, he fled to Gray Terminal, leaving his parents to think that he's dead. He would later meet Ace.

5 years after that, Ace arrives at the Gray Terminal, after having ditched Luffy along the way. Sabo tells Ace that he's late and that he (Sabo) completed his money-collecting job. Ace replies that he also did his share. Ace then handed Sabo his collected money. Sabo counts and says that Ace collected more money than him again. Ace says that they still have a long way to go before they can buy a pirate ship. Sabo then puts the money in a hidden underground stash, admiring their cumulative work of five years, and Ace tells him to close it because someone else might see them. Luffy, overhearing their conversation, suddenly shows up and says that he wants to be a pirate too. Sabo and Ace, however, are not happy to find that Luffy finally managed to successfully tail Ace all the way to the Gray Terminal. Determined to keep him from telling anyone their secret, they eventually decide that Luffy must be killed and proceed to tie him to a tree. However, they are unable to decide who should do it, since both of them have never actually killed anyone before.

Before they can decide, they hear someone approaching and untie Luffy to go hide. They then see that the person that Ace stole the money from is Porchemy of the Bluejam Pirate crew. It is revealed that Sabo and Ace are actually quite notorious thieves, even in the lawless Gray Terminal. The two suddenly notice Luffy went missing and then see that he was caught by Porchemy. Luffy calls out to Ace for help. Recognizing the name, Porchemy decides that Luffy must know something about the stolen money, and Sabo and Ace both watch as Porchemy takes Luffy away.

Afraid of having their treasure taken, Sabo and Ace go to the Midway Forest to take the treasure somewhere else, since he thinks that Luffy would soon reveal them their location. It took all the time until sunset, when Sabo goes back to the tree, he tells Ace that Luffy hasn't told them anything. So they run to where Luffy was beeing tortured to free him, they break trough the wall when Porchemy was about to kill him, after releasing Luffy, Ace stays behind to fight Porchemy because he would never run when facing an enemy, Sabo yells to him to stop it, because he wouldn't face an ordinary person, but a pirate with a sword, and he could die if he tried to do so, still, Sabo joined Ace in his fight, and they defeated Porchemy. Back at the forest, Sabo tell Ace to stop this "wouldn't run when facing an enemy thing", and now the Bluejam Pirates wouldn't stop chasing them, Luffy is crying and thanking Ace for saving him, though Ace doesn't like it, and tries to hit Luffy, but is held by Sabo. Sabo now tells them that from now on, their lives would be targeted by pirates, so they wouldn't be safe anymore, so he goes with Ace and Luffy to Corvo Mountain to live with them and the Mountain Bandits, when he arives in there, he meets Dadan, though he already heard things about her, and so had she heard things about him. Sabo stays with the Bandits for an undetermined amount of time, during which he, Ace, and Luffy fight or hunt the wild animals, fight the outlaws in "Gray Terminal", and the punks in town, so that they acheive a mild level of notoriety.

As they cause trouble into Edge Town, his father sees and calls his name. After that, Sabo reveals the truth to Ace and Luffy, who dont seem to find that particularly shocking. Then he, Ace and Luffy share cups of alcohol to become, as Ace said, brothers.

After some time Sabo's father, along with the Bluejam pirates find the trio. As there is no other way, since his father has payed the Bluejam pirates to deal with Ace and Luffy, presumably by killing them, Sabo finds no other choice but to follow his father in order to let Ace and Luffy escape. He is seen walking away from his "brothers", crying while Ace is screaming behind him trying to stop him.
