Wapometal[3] is a special kind of alloy that was inadvertently invented by Wapol when he was turning garbage into toys during his cover story, manufactured via his Baku Baku no Mi powers. It was this metal that turned him from a homeless bum into a very wealthy CEO of a toy company. His wapometal toys were so successful, the World Nobles granted him a new kingdom as a reward.[4]
Though it is not stated by name, the Vinsmoke FamilyRaid Suits are also said to be a shape-memory armor, and, like the General Franky, have proven to be fire-resistant.[5]
↑One Piece Manga and Anime — Vol. 86Chapter 869 (p. 8-9) and Episode 839, Perospero describes the Vinsmoke Family Raid Suit as a flameproof shape-memory armor.
