Metallica

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

About
Metallica has the ability to manifest itself inside Risotto's body as a swarm of small beings. It can remove iron within any living body that's within range. When the target loses too much iron in their blood, they would die. He can also use the iron in his own blood to his advantage as well as removing iron from other objects, such as when he formed knives from the iron within the earth. The stand also has the ability to manipulate iron using magnestism. 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.

Last, 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.
