Kimimaro—Naruto Series

Kimimaro is a character from the Japanese manga Naruto and its spin-offs. He is the last survivor of the Kaguya Clan, possessing the Kekkei Genkai “Shikotsumyaku” (Dead Bone Pulse). Kimimaro was chosen by Orochimaru and became one of his most loyal followers, dedicating himself entirely to Orochimaru’s cause. He is considered the strongest among the Sound Five.
Kimimaro was a master of taijutsu and possessed extraordinary strength. However, he eventually succumbed to a severe illness and died during his battle with Gaara. During the Fourth Great Ninja War, Kimimaro was resurrected by Kabuto Yakushi using the Edo Tensei, only to be released from the technique by Itachi Uchiha, allowing his soul to find peace.Driven by an insatiable ambition, he is a master of ninjutsu research and covets the Sharingan. Having witnessed countless deaths and understanding the fragility of life, Orochimaru strayed onto a dark path. He believed that the human body harbors untapped power, leading him to pursue immortality in order to master all ninjutsu and uncover the world’s ultimate truth.
Orochimaru’s ambitions were repeatedly thwarted. In the battle between Sasuke and Itachi, he was sealed by Itachi’s Totsuka Blade. Later, during the Fourth Great Ninja War, after seeing Kabuto’s downfall, Orochimaru sought to witness a life completely different from his own, leading to a profound awakening. After being resurrected by Sasuke, he used the Edo Tensei to revive the first four Hokage, and alongside them and Team Taka, headed to the battlefield to aid the Ninja Alliance.
Following the war, Orochimaru was no longer classified as a rogue ninja by the Hidden Leaf Village. He was permitted to continue his experiments as long as he did not harm others, eventually creating synthetic humans Mitsuki and Log and settling in the village.
