Shinnō

was the main antagonist in Naruto Shippūden the Movie: Bonds. He was the sensei of Amaru, as well as a medical-nin from the Land of the Sky.

Background
In the past, Shinnō taught Orochimaru several forbidden Reincarnation Ninjutsu. Thirteen years before the start of the series, Shinnō came to one of the villages in the Land of Fire, claiming to be a former shinobi who turned away from the path of battle to help save lives. In truth, he is an agent from the Land of the Sky, seeking for the scroll to unlock the powers of the Zero-Tails in order for his own country to gain immense power for world domination.

Some years after entering the village, an orphaned girl named Amaru fell terribly ill. While the villagers avoided her for the fear of being infected, Shinnō went straight to her house and saved her life, after hours of nonstop surgical operation. He was then welcomed as a celebrated member of the village, and accepted Amaru's request to take her in as an apprentice in the medical arts. Under this cover of a benevolent doctor, however, Shinnō plotted to have the Zero-Tails feed on the villagers' negative emotions over many years time, in order to gather up large quantities of Dark Chakra.

Personality
At first, Shinnō appeared to be a very kind-hearted doctor whose purpose in life was to save lives of others. He would turn away from battle in order to prioritise his motives of saving as many people as possible, and not be prejudiced with who the patient is: he saved Amaru from a terrible illness that led other villagers to shun her due to fear of being contaminated, and then accepted her as a disciple in the medical arts. He was also encouraging, as when Amaru emulated to look like him, which led to the other villagers to laugh, Shinnō instead complimented her, and encouraged her to work hard to achieve her dreams. Shinnō's desire to save lives led him to be fully willing to sacrifice his life to save Amaru from a trap, and giving her his bandanna as a way of entrusting everything to her.

However, this was all later proven to be a façade; Shinnō's true character is manipulative, cruel and arrogant. He worked for fifteen years undercover as the kind doctor, earning the trust of the people, in order to harvest a large amount of Dark Chakra from them by using the Zero-Tails, yet acting kind to Amaru for all the time to discreetly accomplish his true goal. He had no care for other people's lives, despite his incredible medical skills, and uses his knowledge of the human psychology to manipulate their emotions and actions. When the truth came out, he ruthlessly sneered at Amaru's despair, claiming that if anything is weird, is how he acted for the last fifteen years, that he never once considered their master-student relationship to be anything more than nonsense, snatching back the bandanna he gave her and ripped it to pieces, and mockingly laughed at her confession of her love for him. He is also very arrogant, as he claimed that the throne inside the Ancor Vantian worthy of a king, which he thought to be himself, and brutally assaulted Naruto for damaging it, even when he was the one who threw him against the throne, and giving himself the title. After being stripped of his powers by Sasuke's attack, Shinnō lost his composure, and tends shout out loud of the capabilities he has when merged with the Zero-Tails, and the consequences of its release.

Appearance
Shinnō was an elderly man with long grey hair that flows out at the back, and muttonchops connected to his beard of the same colour. His eyebrows were thick and of a darker grey, but neatly trimmed. He also had yellow eyes with dark bags around them, and tear troughs under them, giving a somewhat stern look, similar to Itachi and Fugaku Uchiha. In his false persona, his eyes would have a kind and generous look, but once revealing his true colours, the kindness was replaced with an arrogant and sadistic look.

He wore a black shirt with a white gi with brown and blue edges over it, and further a sleeveless red jacket with gold sidings over that, and simple blue pants. He also originally wore a dark red bandanna, which he gave to Amaru before his presumed death.

After using the Body Revival Technique in combination with Dark Chakra to increase his strength, Shinnō underwent a great physical change in his body: his hair and beard grew wild and much longer, as well as blackening in colour. His eyebrows became black and wildly thicker. His muscles greatly expanded, which caused his clothes on his upper body to burst, leaving him bare-chested, with only shreds of the sleeve around his wrists. All this made him look younger and much more physically fit. The creases under his eyes and the dark bags around them also seem to have disappeared.

However, after being struck by Sasuke in his tenketsu and causing a backlash in his attempt to use Dark Chakra, Shinnō became a heavily emaciated old man, with his hair turning grey again and falling out, leaving him beardless, no eyebrows, and bald on top, with only wisps of hair at his side, and stubble in where his eyebrows and beard used to be. The creases under his eyes also returned.

Abilities
Shinnō repeatedly proved to be a very intelligent, insightful and cunning shinobi. These factors paired with his ninjutsu prowess and dark chakra served to make Shinnō a powerful shinobi.

Intelligence
Despite having little care for human life, Shinnō demonstrated remarkable medical knowledge and prowess without the aid of chakra. With only basic medical tools, he performed flawless surgeries to save people from near death. In addition to the human body, Shinnō also demonstrated great knowledge of the human mind. He had repeatedly shown himself able to understand how people think and exploit it to suit his needs. He used this ability against Amaru, saying that people never suspect the one that saves their life. With this advantage, he is a very skilled manipulator, acting as a kind-hearted doctor for 15 years, while discreetly harvesting a large amount of Dark Chakra from the villagers' hatred of the Zero-Tails. He pretended to sacrifice himself for Amaru in order for her to succumb to the beast's control and release the Dark Chakra for him. Orochimaru expected that Shinnō had invented more reincarnation techniques since their previous encounter, indirectly showing a great level of confidence in his abilities.

Ninjutsu and Physical Prowess
In terms of ninjutsu prowess, Shinnō's skills focused mostly on his knowledge of chakra and human physiology. He knew many Reincarnation Ninjutsu, which he taught to Orochimaru, and a reason why Orochimaru wanted Sasuke to bring Shinnō back to Otogakure, believing that the doctor may help extend Orochimaru's host's vitality. He was even able to easily kill, or injure a person to the point of appearing dead, and then resurrect said person, even if it was himself. Shinnō was also well versed in Fūinjutsu, being capable of activating, and subsequently controlling, the flying fortress of Ancor Vantian through a seal.

With his knowledge of Dark Chakra, Shinnō was shown as able to unleash a powerful transformation to take a human being well beyond the normal limitations. By combining his signature Body Revival Technique, which grants tremendous self-healing might, with the Dark Chakra, Shinnō was able to transform into a superhuman body that can freely access his chakra without hand seals or any apparent effort of chakra build-up. This grants him great raw physical strength, demonstrated when he brutalised Naruto with punches that sent him flying all over the room and shattering the rock structures from impact, as well as incredible speed that made it look as though he was teleporting to Naruto's backside. This form manipulates the understanding of "Destruction and Rebirth" of muscles that makes it stronger to increase the body's strength. He was even able to unleash Dark Chakra in forms of powerful widespread or condensed shock waves or bolts for tremendous internal damage and claimed to be able to freely access all Eight Gates without any drawbacks as long as he still had access to enough Dark Chakra. He would make claims that this was the ultimate body. Upon being injured by Sasuke, Shinnō merged with the Zero-Tails to gain its powers and Dark Chakra, as well as manipulating the flying fortress Ancor Vantian. Thanks to Sasuke's efforts, the Dark Chakra began to cause Shinnō to wither away both mentally and physically, explaining Shinnō's increasing instability as he neared his end.

Plot Overview
When first introduced he and Amaru came to Konohagakure to get help for their village when the Land of the Sky appeared. During which, he demonstrated tremendous medical prowess by saving the lives of several near-death victims from the Land of the Sky's attack. He and Amaru were then escorted back to their village by Naruto, Sakura, and Hinata. To their horror, when they arrived they found the village in ruins. When Amaru accidentally set off a trap, Shinnō quickly jumped in to save her seemingly at the cost of his own life.

Later, he reappeared perfectly fine and revealed he used a special technique to create the illusion of death. He also revealed his affiliation with the Sky Ninja and that the kind doctor he portrayed for years was nothing but a lie to gain Amaru's trust. He also revealed to have been harvesting the Dark Chakra of the Zero-Tails from the villagers. He then used the dark chakra to transform into what he called the "Ultimate Body", gaining tremendous physical prowess and the ability to freely manipulate his chakra.

Initially, Shinnō repeatedly and effortlessly demolished Naruto despite all his attempts, but after Naruto realised Shinnō's power came from Amaru's negative emotions from feeling betrayed, Naruto helped her to let go of those feelings, stripping Shinnō of his power source and enabling Naruto to defeat him. Before the final blow could be made, Sasuke appeared and intervened as he was ordered by Orochimaru to retrieve the man.

Already seeing through Shinnō's power, Sasuke used his Chidori Senbon to disrupt Shinnō's chakra flow, tricking Shinnō to strip himself of all his power and reducing him to a withered old man. Growing desperate, Shinnō surrendered to Sasuke the scroll bearing the secrets behind his Body Revival Technique (he reasons that Orochimaru was purely interested in the contents of the scroll itself, not him), buying enough time for him to retreat to a chamber housing both the main source of dark chakra as well as the Zero-Tails. There, he merged with the Zero-Tails' seedling and attempted to finish off Naruto and Sasuke once and for all. But once the two unleashed the Nine-Tail's and the Cursed Seal's chakra, they were able to overfeed the cocoon, which caused it to release them. Naruto released demon fox chakra then began to get absorbed back into the Rasengan he created, creating the Tornado Rasengan. Shinnō puts up a barrier to defend himself from the attack and Naruto's Tornado Rasengan hits the shield and the two reach a stalemate. Sasuke uses his Sharingan to see Shinnō's weakness which is the large tower that he is connected to. Sasuke activates his second Cursed Seal form and cuts the tower deactivating Shinnō's shield and allowing him to be hit by Naruto's Tornado Rasengan, ripping him and the Zero-Tails from the stone wall that the cocoon was bound to. With the beast freed from its rein, Shinnō creepily emerged in a snake-like fashion, taunting the two for releasing the demon from its shackles, before it burst out of his emaciated body in a berserk mode, killing him once and for all.
