Hanzou

Hanzou also known as Hanzou of the Salamander Sanshouuo no Hanzou was a legendary ninja who was the former leader of Amegakure. He was very securityconscious being guarded twentyfour hours a day and having anyone who wanted to see him thoroughly searched. He became famous around the time of the Second Great Ninja War. Little is known of his abilities aside from his riding on the head of a giant salamander presumably a summon but he was so powerful that he with his summon fought off all three Sannin. After their battle he was so impressed with their strength that he decided to leave them if they agreed to accept the title of Konoha039s Legendary Three Ninja Densetsu no Sannin This makes him responsible for the naming of the trio039s title. Being capable of defeating all the three Sannin headon Hanzou is easily a kagelevel ninja. His power was such that Jiraiya expressed intense shock upon hearing that Hanzou had been defeated by Pain. Hanzou039s insecurities later got the better of him when a group of ninja lead by Yahiko Nagato and Konan began a quest to end war through unorthodox means. He viewed these ninja as a threat to his power and sought to get rid of them. He then teamed up with the ANBU Root039s leader Danz to kill the group039s leader Yahiko in a treacherous manner. He was later singlehandedly killed by Pain under unknown circumstances. The hatred that Nagato had for him for causing Yahiko039s death was so severe that he conducted a systematic genocide on anybody even remotely associated with Hanzou with the exception of Danzou who somehow escaped the carnage.
