Power of the White Snake

The is a general term on Orochimaru's ability to heal from any form of injuries, due to his years of experimentation on his own body to extend his lifespan and survival rate, which turned him into a giant white snake that enables him to utilize Living Corpse Reincarnation on a victim when the time is right. Aside from increased regeneration, Orochimaru can also reconnect his body with snakes should be bisected, or if the injuries are too severe to heal, he can shed his skin to regurgitate a new body, free from all damage.

When Sasuke absorbed Orochimaru, he too gained much of the White Snake's ability to heal faster than normal, as well as shedding his skin to escape the Amaterasu, though the latter feat took a toll on Sasuke's chakra reservoir. Kabuto also obtain the ability by integrating his master's cells into himself prior to Orochimaru's return.
