A (Fourth Raikage)

A is generally characterised as stern, outspoken and decisive. It also becomes surprising when someone manages to convince him to change his mind. After becoming Raikage, A grew humbler as he referred to himself as "washi", a humble term used by old men, instead of "ore", a prideful way of saying "I" or "me". He believes that actions and strength mean everything and that ninja should never compromise or bow down in front of each other. Similarly, he views jinchūriki not as individuals, but as tools of villages that have no right to speak for themselves. He can also be somewhat hypocritical, voicing his disdain at the other five Great Nations for letting their finest ninja go rogue, while denying his own village's shameless acts, such as kidnapping and stealing secrets from other villages' secrets, and going back on promises. However, he rationalises his actions on the goal of wanting to protect his village, willing to sacrifice allies for the greater good. Despite his militant demeanour, A has quite an emotional side; his short temper and eagerness can cause him out to act recklessly with regards to certain matters, including bursting through his office window to attend the Kage Summit and smashed the table when the conversation. Many people are left exasperated by A's rash behaviour, commenting that it undermines his position as Raikage. However, A has shown a loyal and responsible side, telling Darui not to blame himself over his lost arm and that Darui is his right-hand man.

Serious as he can be, A also loves and deeply cares for his family, especially his adoptive brother Killer B. Since the day they became partners, A and B bonded deeply as they completed missions and honed their skills together as the A–B Combo (エービーコンビ, Ē Bī Konbi). When B became Gyūki's jinchūriki and A's father died, A became determined to keep his village and B safe, confining his brother's movements to the village even if it went against B's personal wishes. As such, he is upset by his younger brother's capture by Akatsuki, and even more so upon discovering it was a ploy for B to have a vacation, swearing to punish him with his "Iron Claw". At the same time, A claims he has resolved to kill his brother if the situation ever called for it. When confronting his older brother during the Fourth Shinobi World War, B points out the flaw in A's viewpoint: his over-protection of B prevents him from acknowledging and believing in B's own strength. When B and Naruto prove their worth by surpassing A in strength and speed respectively, A realises they are truly essential in ending war and lets them pass. A benefits greatly from serving in the Allied Shinobi Forces as well. He was initially distrustful of other villages for their connections to Akatsuki, but now accepts them as comrades, expressing care when they start to over-exert themselves or when they save him on the battlefield. A and Tsunade have somewhat of a rivalry and he is often critical of her, but he concedes her as a valuable comrade and shows concern for her during their battle against Madara. A is also capable of forgiveness although rarely. Despite his hatred towards Sasuke for his attempt to kidnap Killer B and his desire to kill him in retaliation, as well as the loss of his left hand from their battle, A recognises Sasuke's remorse for his crimes and decides to forgive him.

A has dark skin with a large muscular build, white hair (blond in the anime) combed back, a small moustache and goatee. His face has pronounced cheekbones and tear troughs under his eyes, and a prominent crease across his forehead. He has pointed canines and his top lip also has a darker hue than the bottom one; traits he inherited from his father. During his fight with Sasuke, he amputated his left forearm after it was burned by Amaterasu. A often wears a white haori without a shirt underneath and occasionally the traditional Raikage hat. He has black Fūma Shuriken tattoos on both shoulders and originally wore large, golden vambraces on his wrists, though he discarded them after the Five Kage Summit, wearing one on his remaining arm briefly near the start of the Fourth Shinobi World War. He also wears a gold belt around his waist with a boar's face engraved in the centre, black pants with torn ends, Kumo-nin shin guards, and shinobi sandals. All of these aspects combined give him the appearance of a professional wrestler. After relinquishing the role of Raikage to Darui, A began wearing a simple black kimono held closed by a white sash. He has also begun balding with visible wrinkles.

As the Fourth Raikage, A is an extremely powerful shinobi, being chosen as the Supreme Leader of the Allied Shinobi Forces, even after losing his dominant arm. His signature fighting style combines the elements of ninjutsu and taijutsu to form nintaijutsu. Using it, he could easily directly engage in battle with a tailed beast, defeat a fully transformed Jūgo, and overwhelm a Mangekyō Sharingan-wielding Sasuke.

Greatly belying his large built, A is naturally quite fast and efficient in his movements, able to intercept an opponent before they realise he has approached them. Until Naruto Uzumaki's Nine-Tails Chakra Mode, A proclaimed to be the world's fastest ninja since Minato Namikaze's death. A also possesses an enormous amount of strong chakra, comparable to that of a tailed beast, according to Karin. A has enormous physical strength. With a single hand, his feats included lifting a massive two-handed barbell, smashing through walls, severing one of the Eight-Tails' horns; and breaking through Susanoo, an "absolute defence". When blocking one of A's blows, while empowered by the Nine-Tails Chakra Mode, Naruto claimed that he felt like he was being struck by a mountain, and believed that a direct hit would end him if he wasn't careful. A prefers to use wrestling-style moves rather than standard taijutsu, such as powerbombs, backhanded chops, take-downs, and leg drops. A inherited his father's immense durability, having survived being transported by Mabui's Heavenly Transfer Technique unharmed. His pain tolerance is high as well, not flinching from cutting off his own arm to escape Amaterasu's black flames.

A's nature transformations include Lightning, Earth, and Water Release. His signature technique is the Lightning Release Chakra Mode. By encasing himself in lightning chakra, his thought processing and already immense physical parameters are greatly enhanced. His raw speed and reflexes become comparable to the Yellow Flash. Even the Sharingan had trouble tracing his movements. This speed allows him to create after-images, and evade point-blank attacks. His durability is enhanced to the point of withstanding otherwise fatal blow with no more than a small cut. His strength becomes just below that of Tsunade and his offensive might can unleash an extremely powerful and fast punches. Alternatively, he can collaborate his Lightning Release with a Water Release user to power-up their technique to add an electrocution-induced and paralysis effect.
