Kabuto Yakushi spent most of his life as a spy working for many different individuals, organizations, and countries during his life. His natural talents in intelligence-gathering and medicine attracted the attention of Orochimaru when he was younger, who made Kabuto his right-hand man. At times, Kabuto can seem quite open, more than willing to approach people, and always confident in his own words and actions. By his own admission, he is an introvert who doesn't like to be looked at and who wants to stick to the background. He can be very critical of others, dismissing their personal desires, and outlining all the flaws he perceives them to be making. To those he feels are deserving, he is nothing but polite, regarding them with deference, using the appropriate honorifics, and chastising those who don't do the same. He can be cruel, preying on sensitive topics in order to rile someone up and punctuating his comments with sarcasm. Other times he is kind, putting himself at risk and being helpful for no immediate benefit to himself. The many contradictions of Kabuto's personality are a result of his frequent role as a spy, having spent most of his life-changing identities and loyalties in order to gather information for some organization.
