Powers and Abilities

Gold Experience

Giorno Giovanna finds out he was a Stand User and he is able to summon a stand named "Gold Experience" if he wants. A stand is an entity generated from people's life energy, and each stand possesses a unique superpower. People who were able to summon Stand were called Stand Users. Like all Stand Users, Giorno can summon Gold Experience when he wants or hide it inside his body.

Gold Experience looks like a slender person with a metal helmet and golden skin. As a close-range stand, it can only stay one or two meters away from Giorno after being summoned. Its power (physical strength) was ranked "C" by the standard of stands, which is not incredible. However, Gold Experience possesses the special ability of creating lifes. It can transform inanimate objects into living things like animals or plants, it can also charge life energy to other people's bodies to heal other people, or creating body parts to replace damaged organs. With such incredible power, Gold Experience can be used in a wide range of ways.

Powers of Gold Experience

• Life Manipulation: Gold Experience can charge life energy into other objects by touching. This ability can be used in many ways. It can make plants grow faster or heal other people and animals by touching. By charging life energy, it can transform inanimate objects into animals like insects, frogs, and snakes. Gold Experience can also transform inanimate objects into body parts, Giorno can use created parts to replace other people's or his own body parts. He can heal other people by replacing damaged organs in this way, although it's a painful process. Gold Experience can also transform other people's body parts into animals. After this transformation, animals transformed from a certain people's body part would automatically search and follow its owner. Life energy charging also has a rarely used effect on other people. When punching other people's bodies, Gold Experience can charge a large amount of life energy which accelerates other people's feelings. Then people who get hit will feel his mind escapes from body, this person will lose control on his body for a while.
• Fast Punches: Although Gold Experience doesn't have an incredible physical strength like Star Platinum, its speed was ranked "A" by the standard of stands. Gold Experience can throw fast punches with speed enough to left multiple afterimages and makes sounds like a machine gun. Giorno can still severely hurt his enemy by a round of fast punches.
• Reverse Attack: A rarely used power of Gold Experience. When directly hit by an attack, Gold Experience seems can absorb the impulse and reverse back to the attacker.

Gold Experience Requiem

After being stabbed by a Stand-creating Arrow, Gold Experience evolved into a stronger stand named "Gold Experience Requiem". Gold Experience Requiem went out from Gold Experience's body after it cracked. Its head top splits, looks like a crown grew out from its head. This new stand has its own consciousness, it automatically protects Giorno and can even speak. Gold Experience Requiem possesses a new power which is reverting anything to "zero". It also has largely enhanced power and strength compare to Gold Experience.

Powers of Gold Experience

• Revert anything to "zero": Gold Experience Requiem has the ability to revert anything to "zero". This ability's specific effects and limits are described ambiguously in comics. The closest explanation is that Gold Experience Requiem seems able to bend reality to make something not happen if it doesn't want it to happen. This ability seems mainly used to protect Giorno. When any people try to attack Giorno, Gold Experience Requiem will make this attack unhappened.
• Revert death into "zero": Any people who hit by Gold Experience Requiem will experience death for infinite times, people will feel getting killed again and again but never reaches a real death. This ability seems based on a time loop or illusion, but the actual principle stays unknown.
• Enhanced strength: Gold Experience Requiem possesses largely increased physical strength compared to Gold Experience. By sightly flicking a finger toward a small piece of rock, it speeds up the rock like a bullet and penetrates a person's hand.
