Metallica is a swarm of worm-like Stands that inhabit Risotto Nero's body and grant him the ability to control the iron in both his body and his surroundings, including the iron in the bodies of organisms.
Metallica manifests itself inside Risotto's body as a swarm of small metallic beings with stitches across their individual bodies. Their mouths are shaped as though they are moaning or screaming.
Metallica's sessile nature prevents it from attacking on its own, however the magnetic power it produces is highly lethal. Risotto is capable of using this ability to its fullest, particularly to stealth assassinate targets.
Metallica has the ability to freely manipulate iron in the air and ground using magnetism. The Stand is active within a 5 to 10 meter circle around Risotto, and has enough precision to form objects by gathering the iron inside another person's body. By default, he naturally attracts iron.
Risotto Nero prominently uses this ability to turn the iron inside a target into sharp objects such as razor blades, needles or scissors in order to internally damage them. This is shown when Doppio tried to rush Risotto, only to get a face full of needles created from the iron within his blood. Metallica can also use the iron inside its user to manipulate his severed body parts and create staples to reattach them.
Furthermore, the use of iron from a target's body dramatically diminishes the quantity of hemoglobin inside them, reducing the blood's ability to carry oxygen throughout the body. Unable to function, the suffocating body will eventually die if the victim doesn't replenish their iron in time, enabling Risotto to simply wait out his opponent's death.
Iron is one of the most common elements on earth and thus Metallica can also manipulate iron from the environment to form objects, such as forming knives from the iron within the earth and then hurling them at a target.
This ability also carries on to Risotto's blood, as shown when Risotto was shot by Aerosmith, causing his blood to splatter onto Doppio's head and automatically camouflage it with the background, resulting in the image that Doppio saw previously that made him believe that Risotto would blow a hole through his head.
Chapters / Episodes
- Metallica is used as a loading animation in All Star Battle, as the Stand would tend to yell "Looooooaaaad" in the manga.
- The cry of "Loooooooaaaaaad" may be a reference to the Metallica album of the same name.
