Gutsu Gutsu no Mi, One Piece Wiki

The Gutsu Gutsu no Mi is a non-canon Paramecia-type Devil Fruit that allows the user to turn their body into a blast furnace and melt metals inside it, making them a Blast Furnace Human (溶鉱炉人間, Yōkōro Ningen?). The fruit was eaten by two different characters under different media: the first was in the One Piece Premier Show 2013 by Lambor Bukini, and it was reused in the Silver Mine Arc, where it was eaten by Bill. Gutsugutsu (ぐつぐつ?) is a Japanese onomatopoeia for something simmering or boiling
