3-AKAINU
Akainu is the current Fleet Admiral of the Marines.
Akainu has shown to possess tremendous strength and an immense amount of superhuman durability.
He possesses the Magu Magu no Mi, a Logia-class Devil Fruit which grants him the ability to transform his body into magma and manipulate it at will, as well as produce near-limitless amounts of it. His ability is naturally of a higher order than Ace’s pyrokinetic abilities, as the higher heat and smothering abilities of his magma allowed him to successfully harm Ace despite Ace’s Logia-defense, and ultimately kill Ace due to this superiority. According to Oda, Akainu’s devil fruit boasts the highest offensive power amongst all the Devil Fruits.
During the decisive ten day battle on Punk Hazard for the position of fleet admiral, Akainu showed the furious power of his Devil Fruit as he changed the weather of one side of Punk Hazard and left it in a blaze.
Eiichiro Oda stated that if Akainu were to become the protagonist, he is so strong that he could end the One Piece series within a year.
