Sakazuki, commonly known by his alias Akainu, is the current fleet admiral of the Marines, succeeding the previous fleet admiral, Sengoku. Two years ago, he was one of the three admirals, alongside Kizaru and Aokiji. He ascended to the position of fleet admiral after defeating Kuzan in a ten-day duel that left Punk Hazard in its current state. One of his first decisions was to relocate the Marine Headquarters into the New World in preparation for the New Pirate Age.

Sakazuki is a strident follower of Absolute Justice, to the point where his extremism prompted an equally high-ranking colleague to resign from the Marines. He believes that a person's heritage is a reflection of how big of a threat they pose - a belief which caused him to target Portgas D. Ace and Monkey D. Luffy during the Battle of Marineford for the purpose of purging their "bad blood", which ultimately led him to personally kill Ace and attempt to kill Luffy, which he failed to do - managing only to leave a massive scar on his chest while leaving a severe scar on Blizzard's left shoulder.

Sakazuki is an incredibly tall, light-skinned, unusually muscular man (the most muscular of the former admirals). He's about as tall as his fellow admirals, with a square-shaped face, very pronounced facial features, short black hair, and a black mustache and goatee. He usually wears a standard Marine cap and sports a crimson, double-breasted suit, decorated with what appears to be a pink rose on his left buttonhole, as well as the standard white coat draped over his shoulders like a cape (as what most high-ranked Marine officers usually wear). Unlike many high-ranking Marines, he does not wear a tie, but instead leaves his light colored flower-patterned shirt unbuttoned showing his muscular neck and part of his tattoo. He wears black gloves and shoes.

Since the battle at Punk Hazard with Kuzan, the right side of Sakazuki's neck and face are scarred, and a chunk of his right ear is missing.


Sakazuki is an adamant believer in Absolute Justice, and is ruthless in his maintenance of it; his motto is "Thorough Justice". He has a stern, dead-serious disposition, grim, expressionless, and was the most ruthless out of all three admirals two years ago. Despite this disposition, like Eustass Kid, Akainu seems to be able to restrain himself at times, having chosen to spare the life of Jewelry Bonney and her crew after they were left by the Blackbeard Pirates for Akainu to salvage, and letting his colleague Aokiji live despite Aokiji losing to him after a 10 day duel to the death for the position of fleet admiral.

Sakazuki's beliefs led him to go as far as destroying a refugee ship because of the possibility that a scholar could be hiding on board. His logic being that if even one of the scholars of Ohara had escaped with it, the mission would have been a failure, much to the dismay of Kuzan, who called him a fool for overdoing things. Akainu takes his extremist attitude as far as to kill anyone who does not share his point of view, as he attempted to execute Coby for his plea to stop the war.

Additionally, he has no tolerance for Marines who desert their posts, which the only consolation he does offer is that they should not dishonor their families by running away. Caesar Clown also believed that Sakazuki would desire his ideas of mass-murder weapons and inhumane experimentation on prisoners, in contrast to the more pragmatic Sengoku. To Akainu, any Marine who is not willing to fight for justice is not worthy of being called a Marine. Again though, despite all of this, even Sakazuki could not kill his former compatriot Kuzan.

As Fleet Admiral, Sakazuki holds immense pride in the name of the Marines, as when he learned that Fujitora let the world know of what transpired in Dressrosa, Sakazuki was furious. His pride is so great he would rather cover up the ordeal to ensure that the Marines are adamant and credible to his doctrine of Absolute Justice. This conceited behavior also led to him yelling at the Gorosei for declaring Doflamingo's resignation from the Seven Warlords of the Sea as a false report, as he knew the world's confusion would damage their trust in the Marines.

Despite his position as an admiral prior to promotion, Akainu is willing to lie to and/or deceive his enemies in order to achieve Justice. So far, Akainu's manipulations have been incredibly successful, such as when he managed to deceive Squard through Sengoku's master strategy, or insulting Whitebeard to get Ace angry enough to stop his attempt at escape. He finds people who attempt to interfere with him as nothing more than irritating obstacles. Furthermore, he seems in many ways unafraid of older legends and comments on this when Whitebeard claims to his men not to be intimidated by Garp, while Akainu says that he and Garp are of the same generation and promptly attacks him. While other Marines, such as Sengoku and Garp, share a decent amount of respect for their accomplished enemies, Akainu has no such empathy, instead disparaging them at every chance he gets.

Prior to Sengoku making it public, Akainu is one of the few who knew that Luffy and Aika was Dragon's children. It is unknown if he has some past relationship with Dragon or if it was simply common knowledge among the higher ranking Marines that Dragon is Garp's son. As such, Akainu deems that both Luffy's and Aika's mere existences, due to being Dragon's children, is enough to be a threat to the world and therefore must be eliminated. He also deems the existence of Natsu's, like Luffy and Aika's, is a threat and must be destroyed, due to him being raised by a Dragon named Igneel and having declared war on the World Government for the organization not showing any regard for human life, something which angered the Fleet Admiral for being questioned on his own morality.

In fact, Akainu's beliefs about heritage run deep enough that he declares that even if every other pirate escapes, he would personally ensure that neither Ace nor Luffy were allowed to leave the war alive due to their bloodlines, and personally eliminate the young Aika because of her relations to Dragon. This conviction fueled Akainu even to the point of actively hunting Luffy himself, even though Blackbeard was destroying Marineford at the time.

He also does not see it as his business to involve himself in the business of the Celestial Dragons.


Powers and AbilitiesEdit

Magma-Magma Fruit: A Logia-type Devil Fruit that allows the user to create, control, and transform into magma at will, turning the user into a Magma Human. The main strength of this Devil Fruit is that it allows Akainu to produce magma to attack his opponents and also allows him to avoid conventional attacks as they only disperse him in his elemental state. The intense heat can vaporize an iceberg instantly and boil the seawater that the magma lands in. With this power running for a ten day battle, it was strong enough to change the weather of one half of an island into a blazing inferno.

  • Great Eruption: Akainu's signature technique, he transforms his fists into pure lava before throwing it forward, like an over-sized rocket (similar to Luffy's Gum-Gum Giant Pistol or Ace's Fire Fist). The explosion causes volcanic rock to hit the ground, in a method similar to meteors.
  • Meteor Volcano: Akainu creates a great number of magma fists that he fires into the air in order to let them rain down upon the battlefield, causing enormous amounts of area damage. This looks like a cross between a meteor shower and a volcanic eruption.
  • Hound Blaze: Akainu creates a wave of magma, shaped like a dog's head, and launches it against his opponent.
  • Hellhound: Akainu transforms his hand into magma and lashes out at the opponent with a claw-thrust.
  • Cerberus: Akainu transforms his entire being into a giant-sized, three headed dog made out of magma.

Haki: There are normally two types of Haki regular people can tap into: the Observation Haki which allows individuals to sense the presence of others, and Armaments Haki which allows individuals to create an invisible armor around them. There is however a third type of Haki, Conqueror's Haki, that only a few individuals can use. It is currently unknown if Akainu is one of these people.

  • Armament Haki: A form of Haki that allows the user to create an "invisible armor" around themselves. With that, they can protect himself from attacks, and if trained well, use it to deliver stronger attacks. Besides the increase of strength, it is the only form of attack that doesn't involve Seastone that can hit any Devil Fruit user, being able to hit the user's original body even if it's a Logia user. It can also be used in weapons.

  • Akainu cannot swim and becomes immobilized if more than half of his body is covered in water.
  • Armament Haki, Seastone, and a superior Logia-Type Devil Fruit can nullify his Logia intangibility, making him vulnerable like regular people.
  • His regeneration is limited to his Logia body only (similar to Kuzan).
