Clone Snakes

After implanting Orochimaru 's DNA, Kabuto used some of his cells to develop a large amount of tiny snakes that multiply at a rapid rate and can merge into either a clone of another living being using a genetic sample or a larger serpent for combat. They also have incredible regenerative abilities. Kabuto not only created a clone of Hidan using this technique, he also created one of Naruto with Kurama's chakra as well. However, for Hidan, the clone snakes have a short lifespan, with what they form into eventually suffering a cellular breakdown within 48 hours of existence.
