Kankurō

Kankurou is Gaara's and Temari's sibling. He is a puppet master. His main puppet is Karasu, an offensive puppet with concealed blades covered in poison.

The Chunin Exam
Kankuro first appears the day the Chunin Exam is announced. He is seen with his sister, Temari, and an unexplained bundle on his back by Naruto and Sakura while tormenting Konohamaru and the other children. Naruto demands that he stop, but Kankuro pays him no mind and easily overpowerss him physically. He is stopped when Sasuke manages to hit him in the arm with a rock. Kankuro, surprised that Sasuke could manage to sneak up on him - let a lone land a hit, hints at wanting a fight. As if threatening, he removes his bundle which Temari calls "Karasu." The situation is diffused, however, when Gaara appears. Kankuro, who at this point had seemed unflinchingly confident, is terrified of his brother. When Gaara demands that he stop fooling around, he quickly obeys leaving the other three ninjas confused.

During the written portion of the exam, the Genins are told explicitly not to cheat as cheating will result in a deduction of points to the extent of failure. Most of the would-be Chunin - including Kankuro - realize that the real test is simply to see how well a person can cheat without being caught, and begin using their shinobi skills to stealthily copy other tests. Nearing the end of the exam, Kankuro asks permission to use the bathroom. The test proctor allows it, provided one of the ninjas watching for cheaters accompanies him. While in the bathroom, he refers to the nondescript ninja as Karasu, and asks him for the answers. He chuckles at the fact that no one noticed the extra ninja in the room. On his way back to the exam, the proctor comments that he was busy playing with dolls. Kankuro's reaction to this hints that the proctor knows what the bundle on his back really is.

During the survival portion of the exam, he is seen only briefly by Kiba, Shino, and Hinata while Gaara brutally kills a shinobi from the Village of the Hidden Rain.

During the preliminary duels, Kankuro fights in the third match against Misumi Tsurugi from the Village of the Hidden Rain. Kankuro aggressively takes out his bundle, but before he can use it, Misumi strikes, causing him to defend. Upon contact, Misumi's arms begin contorting impossibly around Kankuro's body until he has completely pinioned all of Kankuro's limbs - causing his bundle to fall on the floor. With his hands poised to break Kankuro's neck, he demands that Kankuro surrender. Kankuro scoffs at the idea, and Misumi follows through with his threat, apparently killing him. Before the proctor can call the end of the match, Kankuro's head suddenly turns completely backwards to face Misumi, mocking him. It is revealed, finally, that Kankuro's bundle is a battle-puppet: a ninja tool controlled by chakra strings. The puppet, called Karasu, had been disguised early on as Kankuro while the ninja puppeteer waited in the bundle for Misumi to drop his guard. With the tables turned, Karasu's arms wrap around Misumi's body and violently constrict. Misumi is now unable to fight, though it is not explained if he is dead, and Kankuro is declared the winner.
