The Sofu Sofu no Mi is a Paramecia -type Devil Fruit that enables the user to transform whatever they touch into a highly explosive, highly flammable substance, thus making that person a Bomb-Production Human (ボム製造人間; Bomu Seizo Ningen). "Sofu" means blast in Japanese, and in all translations has been referred to as the Blast-Blast Fruit. It was eaten sometime before the series by former Marine Captain, Napo Leon before he became part of the Black Parade.
