Hidan (飛段, Hidan) was a member of the Akatsuki Organization. His partner was Kakuzu, despite having a mutual dislike for each other. He wore the "Three" (三, San) ring on his left index finger. The newest member of the Akatsuki, Kisame refers to Hidan and Kakuzu as the "Zombie Combo" (ゾンビコンビ, Zonbi Konbi) due to the fact that in a sense, they couldn't die.
