Affiliation: Former Takigakure (Hidden Waterfall) Age: 70s–80s Birthday: August 15 Zodiac: Leo Blood Type: A Height: 185.0 cm Weight: 63.2 kg A rogue ninja from the Village Hidden in the Waterfall. A large man wearing a black mask. He has short black hair, parted in the middle by a headband-like accessory. The sclera of his eyes are red, and his irises are green. His appearance is so youthful it's hard to believe he's an old man, and he is quite handsome under the mask. His mouth, hidden by the mask, is torn wide and stitched together with thread-like fibers from his own ability. He is shirtless on his upper body and wears dark green trousers. He is fundamentally calm and composed, but he is quick to develop murderous intent when trouble arises. His speech is assertive, ending sentences with "...da," "...da na," or "...darou." He does not use elongated vowels or lazy speech patterns. Through the forbidden jutsu Earth Grudge Fear, he has the ability to take the hearts of others while they are still alive, along with their chakra circulatory system. By incorporating the circulatory system, he can use the nature transformations of the heart's original owner. Kakuzu collects hearts to complete all five nature transformations; at this point, he can use all of them. Furthermore, these hearts can be separated from his body, becoming monsters that look like masks attached to black fibers capable of using that heart's nature transformation. Even if his main heart is destroyed, he can replenish it from the separated monsters as long as all five hearts aren't destroyed. Since he can replenish hearts, attacking him with a large group risks him simply stealing a new heart from one of the attackers. He can stock up to five hearts. This forbidden jutsu was considered a treasure in Takigakure. He manipulates black tentacles emerging from his body. Beyond simply strangling opponents, he can detach body parts or sew severed limbs back together, making it highly versatile. He can also harden parts of his body (like his arms) using Earth Grudge Fear. He frequently hunts bounties listed in the Bingo Book and collects rewards at exchange points.
