I think in the circle of "Naruto", we often hear this sentence: "Naruto has no absolute villain." This sentence is true at first glance, but carefully
Orochimaru used babies to study ninjutsu. After Orochimaru was driven out of Konoha Village by the Third Hokage, he hated the Third Hokage deeply and buried this hatred deeply in his heart. Near the Kingdom of Sand, Orochimaru formed his own team, specializing in capturing ninjas with blood inheritance limits for research. In order to achieve the goal of immortality, Orochimaru even stole many babies to study the art of immortal reincarnation. Orochimaru hopes to transfer his soul into a baby
so that he can exist forever in reincarnations.
Orochimaru used his subordinates to reincarnate in the dirt and killed the Third Hokage. Orochimaru is an extremely cold-blooded person. After killing the Fourth Kazekage, he disguised himself into the Leaf Village and kidnapped the Third Hokage during the Chunin Exam. Because he alone was no match for the Third Hokage, he used the Earth Reincarnation to reincarnate the First and Second Hokages. Orochimaru asked the Third Hokage's teacher to deal with the Third Hokage. He waited for an opportunity to attack. The Third Hokage finally used the Ghoul Seal to seal Orochimaru's hands and two teachers for the sake of the peace of Konoha Village.
Orochimaru designed Tsunade and Jiraiya. Orochimaru could not use his hands after his hands were sealed, but his experiments required his hands, so he kept devouring the souls of others to temporarily replenish the souls of his arms, and many innocent ninjas died as a result. Because he wanted to get the power of the Nine Tails, Orochimaru personally went out to find Uzumaki Naruto and confronted Tsunade and Jiraiya. Orochimaru wanted to kill Tsunade and Jiraiya and make them into puppets for his own reincarnation. .
