Kankuro is a son of the Sand’s Fourth Kazekage. He is the older brother of Gaara and the younger brother of Temari. Kankuro was designed to resemble the traditional Japanese Bunraku puppeteers who wore similar “cat hats.” His battle attire includes using black face paint in patterns on his face. In every new appearance in the series, Kankuro always has a new pattern on his face. In the beginning of the series, Kankuro appeared as a mean bully. He disliked younger children and did not hesitate to intimidate them. Part of the reason for this behaviour was because Kankuro has never gotten along with his younger brother Gaara due to the fear of the Shukaku inside of him and Gaara’s penchant for violence.
However, after the events of the Chunnin Exam, Kankuro and Temari both overcame their differences and became closer siblings. Kankuro became very protective of Gaara, not only because he became the Fifth Kazekage, but because he cares for his brother. When Deidara and Sasori kidnapped Gaara from Sunagakure, Kankuro chased after them to try to save Gaara despite the dangers he faced.
Kankuro practices puppet jutsu, an indirect type of combat system that uses chakra strings to manipulate mechanical puppets filled with lethal poisons and various hidden weapons. The weakness of this type of jutsu is that it leaves the puppet master susceptible to attack. In the beginning of the series, Kankuro was only able to control one puppet, Karasu (Crow). In Naruto Part II, Kankuro has advanced to Jonin rank and can manipulate up to three puppets at once. His other two puppets are Kuroari (Black Ant) and Sanshouo (Salamander).
