|Anime||Naruto Episode #178|
Akahoshi took over as the Hoshikage after the Third suddenly "grew ill" and died. In truth, he and his followers Shisō and Yotaka murdered the Third Hoshikage, when their appeal to lift the ban on the star training was denied.
Upon taking control of the village, Akahoshi reinstated the star training, believing that with the powers from the meteor, their ninja would become invincible and they could compete with the five main countries. When he never told anyone about the side effects of the star training, some of the villagers went against him as Natsuhi and Hotarubi try to hide the star.
Akahoshi was, in his own way, extremely loyal to his village, but that was mostly shown in his ambition for it to become as strong and respected as the five great villages. His methods of obtaining that status and importance showed him as a ruthless and ambitious person who was even willing to endanger the village children in the quest for power. He was also quite willing to commit murder as he brutally slew the Third Hoshikage when his request were denied for the star training to be resumed, proving to be both treacherous and cruel. Akahoshi often showed a maniacal side especially during battle and when talking about his crimes, showing a psychotic grin in the meantime, having neither remorse nor fear of retribution. He even publicly and contemptuously degraded the Third as an incompetent leader for not reinstating the star training. Once he implanted the meteorite into his own body, he relished the newfound power it granted him, expressing that he would have done so sooner had he knew of such power, and that he would have it all to himself, showcasing his selfishness and forsaking the village. Despite these factors Akahoshi was shown to be more inclined to make people do as he pleased by manipulating them and their feelings rather than using raw might, proving him to be, at heart, a schemer.
Akahoshi was a man of pale tone, he had a thin and bony face, blue eyes and a narrow nose. Akahoshi also had lilac-coloured hair with a ponytail and a blue forehead protector.
Akahoshi showed excellent skill in the use of the Mysterious Peacock Method, having been self-trained in its use during the rule of the Third Hoshikage. He could let his chakra take the form of a beast for offensive usage and was also able to form wings for short flight. Akahoshi also displayed great defensive capabilities utilising the special chakra, being able to catch incoming shuriken and return them with a wave of Chakra. He could also absorb the chakra of his comrades to improve his own strength.
After placing the Meteorite into his chest, he effectively fused with it, causing the meteorite to take control of him. His appearance also changed, and his chakra underwent a drastic increase in power. With this increase in chakra, as well as with the meteorite's influence, he was able to create a dragon with the star chakra. With said dragon, Akahoshi could easily overwhelm a large number of Hoshi-nin, as well as Naruto Uzumaki with blasts and waves of chakra.
Akahoshi showed proficiency in tracking and deception, continually deceiving opponents and his fellow villagers, often for prolonged periods of time, proven that none even suspected that the Third Hoshikage had been murdered. His deception and scheming even landed him the position of Substitute Hoshikage. He was also proficient in using a crossbow with deadly accuracy.
Star Guard Mission
Some time later, Akahoshi called upon the services of Team Guy and Naruto Uzumaki to help protect the meteor. He later posed as the mysterious masked ninja and managed to kidnap Sumaru to lure out the mysterious bandit to use as bait for Natsuhi. When Natsuhi arrived, she and Akahoshi battled each other as Akahoshi sends Shisō and Yotaka to fetch the leaf ninja. Akahoshi used his Mysterious Peacock Method: Beast to knock Naruto and Natsuhi into the Valley of Death, which they managed to secretly get out of using the Mysterious Peacock Method: Wings. Akahoshi told Neji Hyūga that Naruto got in the way and that their mission is over.
Akahoshi's true colours were shown to the leaf ninja when Rock Lee and Tenten find Sumaru in his quarters hospitalised and rescued him. Later Naruto and Natsuhi tracked them down by tracking her chakra trail. Akahoshi claimed the meteor after using Sumaru to force Natsuhi to surrender it. Akahoshi then laid a trap at the Star Training Building the which resulted in Natsuhi's death.
Akahoshi gave orders to the adult ninja to eliminate Sumaru, Hokuto, and the leaf ninja shinobi at first sight. Akahoshi later had the adult ninja fire arrows at the Star Training Building that Sumaru was mourning Natsuhi in. When Hokuto and Mizura exposed the side-effects of the Star Training, the adult ninja turned against Akahoshi, especially in that moment when an insane Akahoshi accidentally confessed that he murdered the Third Hoshikage. Akahoshi proclaimed that he was the Fourth Hoshikage and planted the meteor in his chest to get the meteor's ultimate power. Therefore enabling him to use his Mysterious Peacock Method: Dragon. None of the ninja could defeat him until Naruto used the Rasengan to destroy the meteor and defeat Akahoshi with the help of Natsuhi's ghost who was able to save Sumaru. Though he is a prisoner in his own village, Tsunade mentioned that he, Shisō, and Yotaka will be subjected to "severe punishment".
