Used primarily after sustaining massive injury or as a means to elude a seemingly inescapable attack, this technique allows the user to materialise a new body — typically by regurgitating it from their mouth — in a manner that somewhat resembles how a snake sheds its skin.
After emerging, the user's clothing and injuries are completely restored, with even amputated limbs being regenerated. Whilst the technique has the additional advantage of potentially being extremely difficult to detect, its use consumes a great amount of chakra.
- Itachi Uchiha described this technique as an "Orochimaru-style Body Replacement Technique" (大蛇丸流の変わり身の術, Orochimaru-ryū no Kawarimi no Jutsu).
