"Comrades. The descendant of the [hero] has begun his adventure. Let's make sure it is one he will remember."
Kakuzu uchiha is a shinobi of the Uchiha clan and one of the first people to inherit Madara Uchiha's plan after his presumed death, succeeding him as the head of the clan. However, he abandoned the role as leader to pursue the secrets of the Sage of the Six path's power. He becomes the Shinju's first Psuedo-Jinchuriki in the process.
BackgroundKakuzu and his brother were born at an unknown point during the Era of Warring States, just a few years before Madara. During a battle during the era, his father was killed by the Senju clan when he was six years old.This developed a strong hatred towards the Senju clan, leading him to be among the first to distrust them during their call for peace.
AppearanceKakuzu is slim in his appearance, with long hair reach just above his shoulders. He commonly wears a black robe with the symbol of his clan on the back of it. When using the power of the Shinju, he gains a skeletal mask with horns,and his robe an hair both turn white with black ruffles on the cuffs and edges of the robe, as well as gains a long, black horn with a portion of bone covering left side of his head. Underneath the bone is a Rinne sharingan, with only 6 of the 9 tomoe.
While kakuzu is collected, serious, and and dislikes lies, he cares deeply for the welfare of the Uchiha clan, especially for his brother, in a similar manner as Madara cared for Izuna. He has great disdain for the Senju clan, using that as his goal of gaining the power to eradicate them, seeing it as justification for what the shame they brought to his clan. Kakuzu is a self-proclaimed devout lover of peace, hating conflict and believing painful battles should be ended as quickly as possible. When battling against others, he tends to use powerful techniques to swiftly beat his opponent. Kakuzu despises values like justice and honor, the same values that the Senju clan believes in. Kakuzu values Hana Ōtsutsuki like his own flesh and blood, showing her affection that he himself did not recieve from his own family.
Kakuzu is greatly famed for his prowess. having studied all of the Uchiha clan's techniques, he possesses a wide range of talents.
ChakraEver since his childhood, Kakuzu possessed great reserves of chakra, even among his fellow Uchiha. His chakra are so large that he could fight nonstop for a number of hours. He also posessess the ability to absorb chakra without the need of the rinnegan. Through it, he was able to take Kekkei Genkai, as well as portions of chakra from Jinchūriki, such as Matatabi, which he seals into a star-shaped badge on his quest to ultimately achieve the Ten Tails' power.
While he relies mostly on ninjutsu and genjustu, Kakuzu is very skilled at taijutsu.Through great amounts of training,his pain tolerance is very high, stating a number of times that he could continue fighting even if his arm was torn off.
Kakuzu is well-versed in a variety of ninjutsu. his training and studies resulted in him being capable of performing hundreds of techinques; he could place a juinjutsu on a target powerful enough to control them himself; he has a mastery over hundreds fūinjutsu said to be strong enough to control even a Tailed Beast.
As an Uchiha, Kakuzu has a natural affinity for Fire Release, capable of performing multiple forms of techniques. he is shown to be able to use a vast arsenal of techniques, and even manipulate the flames of Amaterasu into shapes, creating weapons. After obtaining the sharingan and, ultimately, the rinnegan, he displays the usage of all nature types, including wood release and other Kekkei genkai. Later in his life, he demonstrates an affinity for Yin-Yang Release, such as pouring his will into chakra receivers to restrict and control those he has pierced by them. Through this, he was the first person to create the Six Paths of Pain.
