Team Kabuto

This team, disguised as Konohagakure ninja, were Otogakure spies that took part in the Chūnin Exams to observe Sasuke Uchiha for Orochimaru. Kabuto proved most successful in this goal, but withdrew from the exams before the preliminary matches. Testing Sasuke's mettle was left to Yoroi, who was defeated by Sasuke in the first preliminary match. Misumi was later defeated by his opponent as well.

Yoroi, Misumi, and their unnamed team leader were not seen again in the manga. In the anime, Yoroi and Misumi made another appearance in the Land of the Sea assisting Orochimaru's scientist, Amachi.

Trivia

 * Kabuto's name (meaning helmet), along with Yoroi's (armor) and Misumi's (sword), makes up the helmet-armor-sword trio.
