Through the use of his "true form" is with his Living Corpse Reincarnation, Orochimaru can transfer his soul to another body and extend his life indefinitely. To use this technique, Orochimaru must leave his former body. Once he has done this, he swallows the new body and transports its current inhabitant to a dimension within himself where he absorbs them, thus allowing him to take over their body. Orochimaru can only perform this technique once every three years, which is also around the time that his new body begins to reject him and forces him to find a new host. Although he might leave their bodies behind, the souls of those whose bodies he has taken always remain within Orochimaru's subconscious. After taking over another body, Orochimaru modifies it to suit his theme of snakes. He can also alter the face of his host bodies to look like his original form.

 

   Orochimaru's other method of immortality are the cursed seals he developed. In addition to his senjutsu chakra, each cursed seal contains a portion of Orochimaru's consciousness, which allows him to share the senses of those who bear his seals. In the event that he is killed or sealed, he can be revived through one of his cursed seals if an individual presses flesh containing his DNA up to the cursed seal and uses the Evil Releasing Method. Through this process, Orochimaru can be completely resurrected any number of times, as long as there are enough remaining cursed seals and pieces of his DNA.
