He stands at 306 cm (10'), making him taller than other massive characters like Jinbe, who is 301 cm. He's about as tall as his fellow admirals, with a square-shaped face, very pronounced facial features, and short black hair. Sakazuki is an incredibly tall, light-skinned, unusually muscular man (the most muscular of the former admirals and being on par with Sengoku and Garp).
Because of his actions, Sakazuki is one of the main antagonists of the Marineford Arc and, after his promotion, he became one of the central antagonists of the series. Sakazuki is perhaps the most strident follower of Absolute Justice in the entire series, to the point where his extremism prompted his fellow admiral Aokiji to oppose his promotion to fleet admiral and resign from the Marines after this effort failed. In the anime, he was mentioned earlier by vice admiral Jonathan during the anime-only G-8 Arc, which aired after Akainu had been revealed in the manga. In the manga, Akainu was first mentioned by Nico Robin during the initial encounter with Aokiji. Upon becoming the fleet admiral, one of Sakazuki's first decisions was to relocate Marine Headquarters into the New World in preparation for the New Pirate Age. During the first half of the series, he was one of the three admirals, as the last one to debut. Sakazuki, formerly known by his admiral alias Akainu, is the current fleet admiral of the Marines, succeeding the previous fleet admiral, Sengoku. Logia For ceremony, see Sakazuki (Ceremony).
