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.
