Sabo

Sabo is the Chief of Staff of the Revolutionary Army, and is recognized as the "No. 2" of the entire organization, being directly under Dragon himself in terms of command. He is an adoptive brother of Luffy and Ace, and the son of Outlook III. He was born into a noble family in Goa Kingdom but decided to run away and live in the Gray Terminal, eventually setting out to sea on his own. 12 years before the present storyline, he was a childhood friend of Ace, and eventually Luffy as well, to the point where the three considered themselves to be "brothers", swearing an oath of brotherhood over sake. Along with Ace and Luffy, Sabo's dream was to become a pirate so that he could set sail and achieve freedom, and made plans with his brothers to set sail at age 17. Despite this, Sabo decided to set sail before Ace and Luffy, and his boat was destroyed by a Celestial Dragon moments later. Sabo was believed to have died from this event, but survived and joined the Revolutionaries.

As an adult, Sabo is shown to have great agility as he easily dodged an attack from a Fighting Fish, as well as tremendous strength, clashing with Jesus Burgess, a pirate known for his titanic strength and a captain of the Blackbeard Pirates first ship, who is also a personal bodyguard to the Yonko Blackbeard, with little effort. He later destroys the entire arena of the Corrida Colosseum, which was tough enough to resist all the previous battles between the New World gladiators. A simple grip allowed him to crush Vice Admiral Bastille's skull and helmet. He is skilled enough to go toe-to-toe with a Marine Admiral and emerge with only a few bruises. He was later able to defeat Burgess, one of the 10 giant captains of the Blackbeard Pirates crew and Yonko's crew member with minimal effort. Sabo's Ryusoken fighting style revolves around the use of his fingers which he refers to as "claws". His fingers are strong enough to break armor, great swords and even skulls with ease and remaining unharmed. He claims his fingers are like the claws of a dragon. He also uses Haki to increase the strength of his fingers. In contrast to Luffy, who readily chooses to target his adversary, Sabo seems to prefer destroying his opponent's weapon first before going head to head against them; this difference in battle approach was what allowed Diamante to notice that Lucy was not actually Luffy when Sabo came to fight in Luffy's place in the coliseum. During his fight with Jesus Burgess, Sabo imbued his arm with Busoshoku Haki in conjunction with his techniques. He can also imbue his pipe. He was strong enough to destroy the armor covering Burgess's right arm, as well as Diamante's weapon. Sabo is the current user of the Logia-type Devil Fruit, the Mera Mera no Mi, which originally belonged to his brother Ace before his death. With it, Sabo is able to become the element of fire and control the flames from his body at will. After eating the fruit, Sabo was instantly able to utilize it to the point of using Ace's signature technique, the "Hiken", which was strong enough to shatter the bottom floor of the Corrida Colosseum, exposing the underground facility. He did later show difficulty of controlling his fruit however, which is typically displayed by new Devil Fruit users. While facing against Issho's Marine platoon, Sabo has been shown imbuing his weapon with fire, showcasing that he quickly attained control of his Devil Fruit power. He also mentions that he still has not grown fully accustomed to his new ability just yet, since he still has a habit of dodging attacks, despite being a Logia-user.
