Team Oboro

Team Oboro was one of the Genin teams participating in the Chūnin Exams. They did not pass the second test of the exam, being defeated by Team 7 and Kabuto Yakushi. The team is seen again in the anime under the leadership of Aoi Rokushō. They try to prevent Idate Morino from completing a race in the Land of Tea, but are stopped again by Team 7; Naruto Uzumaki used his Rasengan to create a whirlpool that sucked Team Oboro into a trench and killed Aoi by sending him off a cliff and into the rocks below with Rasengan. Since it looks like those masks let them breath underwater, it is assumed they survived.

Trivia
