Who is Ace in One Piece?

Ace was supposed to be born five months after his father Gol D. Roger was executed, but his mother Portgas D. Rouge kept him in her womb for an additional fifteen months, i.e. almost a year after Roger died.

Ace was put under the custody of Monkey D. Garp and Curly Dadab. As a child, he came across a lot of people who hated Roger and thought that if he ever had a child, that child would be worthless. This used to anger Ace and he used to beat these people up.

At Gray Terminal, he met with Sabo and they bonded over the fact that they had the same dream, i.e. to become Pirates. They made a headstart in their dream by robbing people in Gray Terminal. Ace told Sabo about Luffy, a kid who was following him around and Sabo told Ace to come to live with him in Gray Terminal. Ace declined his offer.

One day, Luffy overheard their dream of becoming a pirate, and they thought that he should be killed in case he tries to expose them. Before they could do that, Luffy was captured by a big group of Pirates who were looking for Ace, as he had stolen from them. Eventually, Ace and Sabo manage to defeat them and save Luffy.

After this adventure, Ace lectured Luffy about his carelessness. After this incident, the three became the best of friends and always went on adventures together. They swore that they were sworn brothers from now on.

Sabo's father eventually found him and sent his men to get him back. He told his men that they could do whatever they wanted with Ace and Luffy. As Sabo couldn't see his brothers getting hurt, he said that he'll return without throwing a fit as long as his father lets Ace and Luffy go without any harm. Sabo was forced to say that Luffy and Ace had forced him to join him in on their crimes. Ace and Luffy were tied to a pole and their protests were ignored. They were going to be set on fire and as they were approaching and surrounding them, Ace cut himself and Luffy free and they ran away.

As the Bluejam Pirates caught up to them and asked them where the treasure was, Ace told them. However, the pirates took them both with them in order to verify the location of the treasure. When they got to know that Bluejam wanted to take revenge on the Nobles, even Sabo, Luffy lost it and he fought back and attacked them. As they held and hit Luffy, Ace's Haoshoku Haki activated in anger and knocked them all down. They subdued Ace and were ready to shoot him but the Dadan family came to their rescue and together, they beat Bluejam. Daman was able to get Ace and Luffy to safety but was severely injured by the flames, so they went to their hideout to treat her wounds.

Later on, Dogra told Ace that Sabo's ship had been gunned down by a World Noble and Ace wanted to avenge his brother, but Dadan refused to let him do so. Days later, he received a letter from Sabo telling him that he was alive. He decided to set out to sea early and to see his brothers again. This letter set his heart at ease and he went to Luffy and told him that together, they would train and become stronger and start their journey as pirates.

Ace had immense physical strength and endurance levels which were the result of the rigorous training he did as a kid. He had to fight wild beasts to live. He could even beat up thugs. We can see his strength levels in his fight against Blackbeard and his combat skills were quite formidable. He was on par with Yamato and Jinbei. His fight with Jinbei lasted for five days which showed his immense stability and stamina.

Devil Fruit

As a kid, Ace ate the Mera Mera devil fruit which gave him the ability to create, control, and transform his body into the fire. He could create and unleash massive amounts of fire and cause large-scale damage and even annihilate cities. He could also make spears and use them in combat. He got his name as 'Firefist Ace' due to him transforming his fist into fire and shooting it in great sizes. He could make up firewalls for defenses and block his opponents.

Haki

Ace was one of the few people who could use all three types of haki. He knew how to use the Hoashoku Haki, which allows the users to exert their willpower over others. He hasn't been seen using this haki ever since he was a 10-year-old kid. He can also use the Busoshoku Haki, which allows users to use their spiritual energy to create an invisible armor around themselves, giving them offensive and defensive capabilities. He is quite proficient in using it and very skilled at it too.

Lastly, Ace even possessed the Kenbunshoku Haki, which allows the users to use the sixth sense to sense the presence, strength and emotions of others. It even gave the user prerogative abilities.
