technique name: * Dai Funka (大噴火, Great Eruption?):
description: Akainu's signature technique, he transforms his right fist into one made out of pure lava before throwing it forward, like an over-sized rocket, and similar in size to that of Luffy's fist whilst he's in Gear Third. The explosion causes volcanic rock to hit the ground, in a method similar to meteors. This was first seen when he used it to evaporate an iceberg hurled at his fellow Marines by Jozu.
technique name: * Ryūsei Kazan (流星火山, Meteor Volcano?):
description: Akainu creates a great number of lava 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. This was first used to destroy the ice floor Aokiji created along with the pirates who were standing on it. He managed to take out Whitebeard's flagship, the Moby Dick, with this technique. In the anime, the meteors first fly high into the sky and above the clouds, and then fall back down as though they truly descended from space.[10] In the Viz Manga and FUNimation subs, this is called Meteor Volcano.
technique name: * Ganshō Kenga (岩漿犬牙, Magma Dog Fang?):
description: Arguably the source of Sakazuki's nickname, Akainu creates a wave of magma, shaped like a dog's head, and launches it against his opponent. It was first used against Whitebeard, and the technique's name is introduced in the video game Gigant Battle.[ However, it is still unknown if this attack's name is official, as it is not known if Oda gave it.
technique name: * Meigō (冥狗, Dark Dog?):
description: Akainu transforms his hand into magma and lashes out at the opponent with a claw-thrust. This technique is powerful enough to tear off half of Whitebeard's face with a glancing blow
technique name: spinning magma bombs
description: shizuku makes magma out of his fist and jumps up in the air while spining and throwing out magma bombs. which is the size of the Dai Funka.
