Metallica

Metallica (メタリカ) is the stand of Risotto Nero featured in Part V: Vento Aureo. It is named after the American thrash metal band Metallica. 

Powers
Magnetism: Metallica has the ability to manifest itself inside Risotto's body as a swarm of small beings, having the ability to manipulate iron using magnetism. When needed, Metallica can form the iron in a target to be various dangerous objects like knives and tools; this is shown when Doppio has tried to rush Risotto, only to get a face full of needles created from the iron within his blood, and even if that does not prove fatal, the anemia caused by lack of iron in the blood will be. He can also use the iron in his own blood to his advantage too, such as when he re-attached his foot by turning his iron into staples and locking the foot back into place, as well as removing iron from other objects, such as when he formed knives from the iron within the earth.

Light Refraction/Invisibility The stand also has the added bonus of being able to wrap itself around Risotto's body causing him to blend into the background, making him effectively invisible.
