In the state of Impure World Resurrection, Kakuzu retains all the personality traits he possessed in life. He still operates by cold calculation and assesses situations from the standpoint of profit, although now his actions are directed by the will of the summoner. Kakuzu has not lost his mercenariness, but in wartime conditions it takes a back seat to the assigned combat mission. He demonstrates pragmatism and an analytical mind, quickly evaluating the balance of forces on the battlefield. Upon encountering former opponents, such as Izumo and Kotetsu, he admits that he tends to forget those for whom no reward can be obtained. Kakuzu notices Hidan's absence among the resurrected and draws a logical conclusion that his partner was probably decapitated but still alive. He acts methodically, releasing masks to fulfill the role of the "elephant" in the chess metaphor of battle. Despite his involuntary position, his behavior shows no signs of despair or regret — only focus on destroying the enemy. Kakuzu respects strong opponents but does not hesitate to attack without warning. Outbursts of anger characteristic of him in life are muted in the resurrected state by the controlling seal, but not completely gone. He remains a dangerous and unpredictable fighter whose centuries of experience make him a formidable weapon in Kabuto's hands. In battle, he acts as an autonomous combat unit, not needing orders to show initiative. Kakuzu does not show nostalgia for the past, but upon seeing Kinkaku's transformation, he in passing remarks that he has not seen anything like it in a very long time. His worldview, hardened by decades of hunting for heads, remains unchanged even in the face of ultimate destruction.
