Tengatai Tengatai no Mi

Jane Rose was, at some point during her slavery, fed an unknown paramecia devil fruit that allows her to generate and control a black metal, which she refers to as darksteel. this fruit is in effect very similar to Mr 3's wax power. Objects created using this power are fluid and can be easily moulded by her until she solidifies them. once solidified, darksteel becomes many times stronger and harder than ordinary steel, but can no longer be molded or reshaped, unless the construct she forms has a hinge or is segmented in some way to create a joint. She uses this power to generate most of the weapons she fights with on demand, such as bladed tonfa or an axe blade attached to her foot.
