~Orochimaru~

As a child, Kabuto was found by Nonō Yakushi on the outskirts of a battle-destroyed city, with no memory of his past. Nonō brought him to the Konoha Orphanage and named him "Kabuto." He was later recruited by Danzo Shimura's Root organization and trained in espionage, working as a spy for various villages.

• Association with Orochimaru: His natural talents in intelligence-gathering and medicine caught Orochimaru's attention, leading him to become Orochimaru's loyal subordinate and assistant in his experiments and schemes.
• Abilities: Kabuto is an exceptionally skilled medical-nin, considered second only to Tsunade. He possesses a wide range of ninjutsu

Former Konohagakure Ninja: Orochimaru was once a highly talented ninja from the Hidden Leaf Village (Konohagakure), and one of the "Legendary Sannin" alongside Jiraiya and Tsunade, all students of the Third Hokage, Hiruzen Sarutobi.

• Genius and Prodigy: He was exceptionally gifted in ninjutsu, research, and understanding chakra, mastering a vast array of techniques, including forbidden jutsu. He even mastered all five basic nature transformations, plus Yin and Yang Release.
• Obsession with Immortality and Knowledge: A central driving force for Orochimaru is his profound fear of death and his desire to learn all the jutsu in the world. He realized that a human lifespan is too short to achieve this, leading him to obsess over immortality. This pursuit led him down a dark path of unethical human experimentation.
