Body Recreation Technique

Kabuto uses specially-developed snakes to execute the process of recreation and multiplication of another being's cells to create a living clone of them—a process which requires the DNA of the intended target. The spring water produced by The Hole appears to catalyse and speed up the recreation process because of the large "life force" flowing through it. The downside to accelerating the time for maturing the clone is that the cellular snakes composing it have a very short lifespan, with the clone any living up to 48 hours.

Once the clone is created, Kabuto is able to gain control of it by placing a special talisman into its head. Depending on the talisman used, the clone can either become a mindless tool under Kabuto's control, with eyes possessing black sclera and white irides, or allowed to access the original's personality and memories, while possessing their original self's eyes with grey snake-like sclera. Clones produced through this method are also able to use any abilities possessed by their original selves.

Kabuto first used this technique to create a clone of Akatsuki member Hidan by placing snakes containing his DNA into the water produced by The Hole, causing them to quickly form into a humanoid shape, and then giving it life with a talisman. Later, snakes which had entered the body of Naruto Uzumaki created a clone of him upon being forced out. Due to him being Kurama's jinchūriki, the clone was formed in his four-tailed Version 2 state and was able to resist the control of Kabuto's talisman.

Trivia

 * While in The Hole, Kabuto compared this process to a viral infection, presumably due to how rapidly it occurs.
 * The clones created through this method lack clothing, unlike individuals revived with Summoning: Impure World Reincarnation.
