Name in Japanese (translation): Tetsu Tetsu no mi
Capabilities: The user of the Tetsu Tetsu no mi can create and control an endless amount of molten steel. ( if a different metal would be preferred I will change it) The molten metal is a deep metallic grey with bright orange mixed in. The steel created by Vinnic is strong enough to go against eh Magu Magu no mi evenly, while surpassing the Mera Mera. The Tetsu Tetsu no mi can also be refined to the point of its constructs being intricately detailed. The molten metal can even be made into several constructs at once, or fewer larger constructs. Like with aces Mera Mera no mi, the Tetsu Tetsu can be balled up and popped to shoot molten metal everywhere in an area. The uses outside of combat are fairly useful as well, Vinnic can use his construct snake to scout, or if provided a mold he can make cannonballs with his logia, or even provide steel for blades. The Tetsu Tetsu no minis classified as a Logia.
The Tetsu Tetsu no mi user is effected well by Lightening and is vulnerable to standard devil fruit weaknesses.
