Nawaki

Nawaki was a genin of Konohagakure's Senju clan in Naruto, the younger brother of Tsunade, and the grandson of the First Hokage, Hashirama Senju. His grandmother was Mito Uzumaki, making him a descendant of the Uzumaki clan as well. Like Naruto, Nawaki had the dream of becoming Hokage and protecting the village. He shared a similar personality to Naruto, being impulsive, determined, and hating to lose. On his 12th birthday, Tsunade gave him their grandfather's necklace hoping it would help him achieve his dream. However, the day after his birthday, Nawaki tragically died in battle, killed by stepping on an explosive trap. His body was so mutilated that only his hair was recognizable. Orochimaru retrieved his necklace and returned it to a grieving Tsunade. Although his time in the story was brief, Nawaki had a significant impact on Tsunade and the Naruto world. His dream, personality, and appearance were very similar to Naruto Uzumaki, leading some to consider him a past incarnation of Naruto. Years later, Orochimaru offered to revive Nawaki and Dan Kato for Tsunade's help, but she refused knowing that they wouldn't want her to sacrifice others' lives to bring them back.
