|~ Akainu swearing to kill Luffy and Ace|
Akainu (real name: Sakazuki) is the main antagonist of the anime/manga, One Piece. He is one the three Marine Admirals and one of the most powerful fighters the Marines have to offer. He is the current Fleet Admiral as Sengoku's successor. He ate the Magu Magu no Mi (Magma-Magma Fruit) making him become living magma. He is seemingly mean, sly, cruel, heartless, diabolical, and manipulative, so he believes in the Marines motto of "Absolute Justice", which is to punish criminals at any cost. He will kill anyone that he thinks are evil or are an obstacle of justice. He will also not hesitate to kill his own comrades who run away from battle. He will kill them no matter how they beg for mercy.
His debut in the series features him immediately crossing the Moral Event Horizon by destroying a ship filled with innocent refugees of Ohara on the minuscule possibility that a criminal might have been on board, an action that horrified even his comrades. Since then, he rose through the ranks of the Marines and eventually became one of the Admirals, alongside Aokiji (who detested him for his cruelty and fanaticism), and Kizaru.
He is the one who killed Monkey D. Luffy's brother, Portgas D. Ace. His magma overpowered Ace's fire power, and punched him straight through the chest as Ace was trying to protect Luffy. He even tried to kill Coby when he said further fighting would be pointless, but luckily, Shanks saved him just in time. Through this horrible action, Akainu accomplished what no other villain ever could: completely breaking Luffy's spirit.
Within the two year time-skip, Akainu officially became the new Fleet Admiral, officially placing him as the commander of all the World Government's forces, which was later revealed to the Straw Hats by Jinbe at Fishman Island. According to Jinbe, since Akainu's commandeering of the Marines, they have become noticeably cruel under his ideologies of Absolute Justice.
Fleet Admiral Sakazuki became furious to Admiral Fujitora for revealing the true news of Dressrosa incident without even telling him. He asked why didn't he report to him before taking action. Fujitora replied if he report to him, he would have cover-up the incident. He suggests that cover-ups were needed to save the face of the World Government. Fujitora doesn't want to become a hero for something that he did not do. He is argue to the Admiral about the credibility and dignity of the Marine Headquarter. Sakazuki banned Fujitora from every single Marine Bases unless if he can capture both Luffy and Law.

- According to Caesar Clown, Akainu would have probably purchase weapons of mass destruction to enforce justice.
- Akainu is similar to Danzō Shimura from Naruto and Seryu Ubiquitous from Akame Ga Kill!. They are all delusional extremists with a twisted sense of enforcing the law.
- Akainu is the first villain to kill an important character outside of a flashback.
