Raikage

The is one of the five great Kage, leader of Kumogakure and generally known as the strongest in the village. There have been five Raikage so far in the history of the village, each with the given name except for Darui. Each Raikage has had a tag-team partner named, who not only brings out the Raikage's full power, but defends them as well. The Raikage works inside a central blue structure inside Kumogakure.

Trivia

 * As opposed to the Kazekage and Tsuchikage positions, which appear to be inherited within a specific family line or clan, the Raikage title appears to be inherited by Kumo ninja who are closely linked to one another, much like the Hokage position. This is further reinforced when the Third stated his son was to become the Fourth at least a decade before he ever gained said title.
 * The Second was the bodyguard for the First.
 * The Fourth was the son of the Third.
 * The Fifth was the student of the Third and right-hand man of the Fourth.
