Orochimaru - Naruto
“You just don’t have enough information to explain yourself yet. Your glasses, your name, being someone’s child is not something that can show who you really are. But that is fine. If you’re not happy with what you have now, you can just find new things... You see, I also want to find who I really am. That’s why I’m collecting a bit of everything.” [Orochimaru to Kabuto]
Orochimaru is one of the Sannin (Three Legendary Ninja) of the Hidden Leaf Village. He is also the main antagonist of the original Naruto series. His goal is to discover and master all of the secrets in the world, including jutsu and Forbidden techniques. However, claiming that his own lifespan does not give him enough time, he runs scientific experiments and uses other human sacrifices as vessels so his soul can live on and continue his research. Originally a student of the Third Hokage, he wanted to succeed him and become the Fourth to control the village and use to his own beliefs, but was eventually denied and grew bitter, planning on destroying it. He takes on the Second Hokage’s prototype Edo Tensei (revival) jutsu and makes it into what it is today. His base of operations is his very own Hidden Sound Village which he created himself, and works alongside Kabuto, his assistant. In the majority of Naruto and early Shippuden, he schemed on using Sasuke’s body as a vessel, as he is one of the last surviving Uchiha members and Sharingan users after the Uchiha massacre by Itachi, promising Sasuke power in return. Like the other Sannin, he can use the Summoning Jutsu and his animal is the snake.
