Regeneration Ability

This regenerative power enables the user to heal most injuries in seconds, reconstructing the organs and damaged tissues making up the human body to its uninjured state. This technique has a continuous, automatic effect that will heal any damage that the user sustains instantly without the need to make hand seals or even a conscious effort to activate the healing process. By Madara's own claim, this medical technique is similar in nature to Tsunade's Strength of a Hundred Technique of the ninja art Creation Rebirth in power.

The enhanced regeneration granted by this technique is so rapid that even dozens of puncture wounds, on top of various injuries inflicted by the combined physical assault of all nine Tailed Beasts were completely healed in mere moments, with the exception of a severed arm, which Madara instead replaced with an arm from one of White Zetsu's clones.

Trivia

 * After becoming the Shinju's Jinchuriki, Madara claimed that it was impossible for him to be defeated as he gained a form of "immortality" from how far his regeneration's ability had ascended. This is much like Tsunade's own claim, that as long as she has chakra it is impossible for her to die by any means, as such she gains a form of immortality throughout the duration of the Creation Rebirth technique.
