Kimimaro was characterized by his pale skin, vivid green eyes, masculine facial features, two scarlet dots on his forehead which all the members of his clan possessed, and shoulder-length white hair, which he wore divided down the middle on his head (distinguished by an atypical 'zigzag' hair parting) with two separate partings on either side of his face.
Under the wing of Orochimaru, Kimimaro wore a specialized version of the traditional Oto-nin ensemble, consisting of a light lavender, loose-fitting, long-sleeved, zip-up shirt, black pants cut off around mid-calf, bandages wrapped around his ankles, traditional shinobi sandals, and a purple, rope-like belt tied in an inverted bow around his waist. He also wore two red, tube-like hair ornaments; one on either side of his head, securing two locks of his silvery-white hair. He did not wear an Otogakure forehead protector, despite his extreme loyalty to Orochimaru. His Cursed Seal of Earth is applied at the base of his throat, where it is a circular pattern of three curved lines.
Unlike the rest of his clan, Kimimaro didn't have a particular interest in fighting or killing and saw his abilities only as a means to be of use to others. He was a calm and quiet individual who would dedicate himself to whatever mission was at hand. As a child, he was more gentle despite his natural talent for combat and unique abilities which made him the strongest of his clan, as seen from him not wanting to hurt others he had no involvement with, and his interest in flowers. His gentleness is also reinforced by how empathetic and kind he was to Jugo, being one of the few people able to keep Jugo from losing control over himself.
After meeting Orochimaru, Kimimaro developed a strong devotion towards him, bordering on religious zeal or considering him a father figure, seeing Orochimaru's apparent kindness as a reason from him to exist under the notion that serving Orochimaru in anyway is the only purpose he has. Though Kimimaro's relationship with Orochimaru was similar to Haku's relationship with Zabuza, the only difference was that Orochimaru ultimately lost interest in him when he became of no use to him. Regardless, finding a new way to assert his existence, Kimimaro's dedication to Orochimaru was so great that he both willed his body to fight and proved to be an extremely dangerous opponent for the likes of Naruto Uzumaki, Rock Lee and Gaara. Gaara compared the eyes of Kimimaro to those of Sasuke Uchiha's, the eyes of those who only sought to prove their own existence, nothing more. Even after being reincarnated by Kabuto, Kimimaro retained his loyalty to Orochimaru and intended to carry out Kabuto's orders. Gaara commented on Kimimaro to be hasty and a extreme distaste for weak opponents, or "trash" ninja as he put it. As a result, he would kill any he considered "trash" ninja, regardless if they were friend or foe as was with the case of Tayuya for her group's failure to deliver Sasuke in time.
Despite his verbal disrespect of his opponents and over underestimating of their abilities, Kimimaro differs from his four colleagues in two ways: The first having a sense of honor in battle, as demonstrated when he halts to allow Lee time to take his "medicine". Another difference is that he rarely showed any emotion other than surprise, except in moments relating to his ideals as seen when Gaara's insulting of his faith in Orochimaru caused him to become enraged before his death or when Kimimaro cried silently when he lost his usefulness to Orochimaru.
Shikotsumyaku: Kimimaro's abilities came from his kekkei genkai, Shikotsumyaku, which allowed the user to manipulate their own skeletal structure as a means of combat. Specifically, it allowed Kimimaro to manipulate his osteoblast and osteoclast cells, which are responsible for building or breaking down bone tissue. This ability gave him absolute control over the concentration of calcium within his bones, allowing him to control the density or malleability of them. Kimimaro also stated that his bones were stronger than tempered steel. Kimimaro used this ability to wield his bones as weapons in battle, and could use them in the form of taijutsu attacks (which he called dances) to give him a variety of abilities, as well as grant him a near-invincible defense, able to withstand from being crushed by being buried under 200 meters of compressed sand, and most of the impact from even a chakra-enhanced blade, and cut through regular shuriken. He can also grow an entire forest of gigantic bone blades, and even merge with one of them to climb out from underground, allowing a deadly sneak attack. Orochimaru has stated that this was the ultimate taijutsu ability, which is held in high regard, and the main reason why Orochimaru desired Kimimaro to be his next vessel. However as a downside, a user of the Shikotsumyaku abilities, such as Kimimaro has a different bodily structure than others, as Kabuto Yakushi claimed that there had been too little information on his body to give any medical treatment for his terminal illness.
