Kazekage

The are the leaders of Sunagakure. Feared and respected across the world, they are responsible for making Sunagakure a powerful and great village, despite its small size. However, being responsible for raising so many great shinobi seems to come at a heavy price, as all the Kazekage, including the current, so far have met untimely deaths at the hands of assassins. For this reason, the Kazekage lineage is sometimes considered cursed. Full-bodied statues of all the former Kazekage are kept in the room where Sunagakure's council convenes.

Fourth Kazekage Impersonator
After killing the Fourth Kazekage, Orochimaru took on his guise and acted as the Fourth Kazekage for several weeks in order to have Sunagakure assist him in the Konoha Crush. He dropped the guise at the start of the battle when beginning his battle with his former master Hiruzen Sarutobi.

Trivia

 * The colour of the Kazekage's garbs was originally depicted as blue in the anime, but was changed to the manga's green colour in Naruto: Shippūden episode 199.
 * In the third databook, the First and Second Kazekage are mistakenly switched.
 * In Gaara Hiden, it is suggested that the title of the Kazekage is hereditary or that Rasa and Gaara's specific clan/bloodline is extremely likely to produce shinobi powerful enough to earn the position. Gaara even calls his clan the "Kazekage Clan".
