Hidan is the partner of Kakuzu, despite having mutual dislike for each other, and was the second newest member of Akatsuki, at the time of his expulsion from his village. Kisame laughingly referred to Hidan and Kakuzu as the "Zombie Brothers."

Hidan's primary ability was his inability to die, a result of extensive experimenting with the Jashin religion's various jutsu. His immortality allowed him to survive numerous fatal injuries, and almost any form of dismemberment; he even retained his ability to speak after having his head cut off.
