Jiraiya

Jiraiya was one of Konohagakure's Sannin. Famed as a hermit and pervert of stupendous ninja skill, Jiraiya travelled the world in search of knowledge that would help his friends, the various novels he wrote. He was a student of Third Hokage Hiruzen Sarutobi and one of the three "Legendary three Sanin" along with Orochimaru and Lady Tsunade, his former teammates. Jiraiya appears as a perverted old man who occasionally returns to the village Konohagakure, reporting the activities of Orochimaru and the organization Akatsuki. Referred to as the "Toad Sage" and "Pervy Sage", he mentors Fourth Hokage Minato Namikaze and later becomes the godfather and mentor of Minato's son, Naruto Uzumaki.
