From Anime and Manga, Naruto, this is Naruto : Kimimaro Mattel Basic Action Figure . Kimimaro (君麻呂) was the fifth member of the Sound Four, thus temporarily changing their group name to the Sound Five. The original four were forced to accept him as their leader against their will, as Kimimaro’s combat abilities far exceeded all of their skills combined.
Kimimaro was referred to by Orochimaru as the most powerful member of the Kaguya clan, having “abilities that even his war-loving clan feared”. Because of this, he was locked away in a cage for most of his life, only released occasionally when needed to fight other clans. His fighting abilities far outclassed all the members of the Sound Four combined, and his mastery of the Cursed Seal even impressed Jūgo, the source of the Cursed Seal, he said he had not seen such control of the Cursed Seal since Kimimaro when commenting on Sasuke’s control of the seal. In fact, Kimimaro is the only person before Sasuke who could control Jūgo without exerting any efforts. Kimimaro also has a very strong determination, as when his failing body would be impossible to move physically, he forced it to through sheer will, and still proved to be a deadly opponent. The fact that he could fight Naruto, Lee, and Gaara while dying of disease, and never actually being defeated by them, indicates he was an extremely powerful combatant at his peak. See details
