Appearance

Akainu wears a dark red suit, a military cap, and a Justice cape when acting at Marineford. 20

• Stern, severe expression. 20 22
• Often surrounded by or attacks with surging magma. 4 24
• Returns from Ohara covered in severe burns and festering injuries. 46 47

Personality

Akainu is stern, combative, and intensely devoted to an uncompromising interpretation of Marine justice. He considers enemies of the Marines—particularly Ohara and those protecting it—to be evil that must be purged, and argues that the Navy must never retreat. 20 43 44

His pride and temper repeatedly override strategy. He ignores Sengoku's limited reconnaissance order at Ohara, intensifies the bombardment, refuses a withdrawal order, and risks his life rather than concede defeat. 43 44 45 His humiliation at Roya's hands becomes a major source of motivation, driving his training and determination to prove himself. 25 43 45

Abilities & Skills

Magma-Magma Fruit

Akainu wields a magma-based Devil Fruit that grants devastating offensive power and allows him to form and launch molten attacks.

• Meigō — Fires a powerful magma strike; used against Roya's Wood Release barrier and Weevil. 4 44
• Great Eruption — Creates a massive volcanic magma fist capable of destroying several of Roya's phantoms at once. 24
• Dog Bite Crimson Lotus — Forms magma canine heads that bite and burn targets. 24 44
• Meteor Volcano — Launches enormous lava fists; its awakened form affects the surrounding clouds and blankets Ohara in falling magma. 4 5 45
• His magma could burn holes into Weevil's body, but Weevil's regeneration restored the damage within seconds. 44

Devil Fruit Awakening

Akainu awakens his Devil Fruit during his second assault on Ohara.

• Alters the weather by turning clouds into fiery masses. 45
• Produces countless giant lava fists across a wide area. 45
• Remains insufficient against Roya's flaming sword slash, which absorbs the magma attacks as fuel. 46

Combat Ability

Akainu is a high-ranking Marine combatant capable of rapidly analyzing opponents and sustaining prolonged combat.

• Quickly identifies and destroys Roya's Five-Turn Illusion during their promotion match. 24
• Uses Observation Haki to partially elementalize in advance of Weevil's attack. 44
• Endures Roya's Modified Rokuogan, Phantom Susanoo, and a later Ryujin Jakka slash, though each encounter leaves him severely injured. 25 46

Story Role / Major Arcs

Buster Call at Ohara

Akainu participates in the Buster Call against Ohara alongside Aokiji. His attacks, including Meteor Volcano and Meigō, fail to breach Roya's Wood Release barrier. 4 He then joins Aokiji and three vice admirals in attempting to stop Roya's flaming slash, but their combined attacks are consumed; Akainu is severely injured and knocked unconscious. 5

Mary Geoise Crisis

When Roya's floating island falls toward Mary Geoise, Akainu joins Kizaru in attempting to destroy it with Meteor Volcano. Their combined efforts prove inadequate before Imu annihilates the island. 14

Marineford Promotion Tournament

Akainu openly dismisses Roya as an unqualified outsider and warns him against facing him in the tournament. 20 22 During their match, he efficiently destroys Roya's illusions and appears to dominate the opening exchange. 24 Roya then withstands his magma with peak Armament Haki, strikes him with Modified Rokuogan, and crushes him into the training ground with Phantom Susanoo, leaving Akainu unconscious. 25

Second Ohara Operation

Sengoku assigns Akainu to investigate Ohara and destroy it only if its defenses prove weak. Akainu accepts partly to erase the shame of his earlier defeat. 43 He disregards the reconnaissance order, bombards the island, and clashes with the cloaked Weevil. 44

Unable to overcome Weevil's regeneration, Akainu refuses Sengoku's withdrawal order and reveals his Devil Fruit Awakening. 45 He is ultimately defeated by a cloaked Roya's Ryujin Jakka slash, which overwhelms his awakened magma attack. 46

Return to Marineford

Akainu washes ashore gravely injured after the battle. Roya finds and treats him, though Akainu does not realize that Roya was the enemy who defeated him. 46 He returns to Marineford with Roya and is immediately taken for medical care; Sengoku intends to punish him after his recovery. 47

Relationships

• Roya — Repeated adversary. Akainu initially belittles him, loses decisively in the promotion tournament, and is defeated again during the Ohara operation. Roya later secretly saves his life. 20 25 46
• Sengoku — Fleet Admiral and superior officer. Sengoku assigns Akainu to investigate Ohara, later orders him to withdraw, and plans to discipline him for insubordination. 43 45 47
• Aokiji — Fellow Marine officer; they jointly attack Roya during the first Buster Call and are defeated by the same slash. 4 5
• Kizaru — Fellow Marine officer; assists Akainu in trying to destroy Roya's falling island above Mary Geoise. 14
• Weevil — Opponent during the second Ohara operation. Akainu's magma wounds Weevil but cannot overcome his regeneration or physical strength. 44 45
• Spandam — Rescues Akainu and Aokiji after their defeat in the Buster Call, while insulting them as dead weight. 5
• Marine Colonel at Ohara — Invokes Sengoku's authority to order Akainu's withdrawal after Akainu threatens retreating Marines. 45
