Gold Experience is a humanoid Stand of slender build and average height, like Giorno. The top of its head is similar to that of a typical helmet of a soldier, with curved markings similar to the letter J coming down from the eyes on both sides. There are stylized wings on its shoulders and large ladybugs all over its body.
Its design is based on the scarab beetle, as a symbol of creation in ancient Egypt, and on ladybugs, symbolizing regeneration, with its angel wings as a symbol of peace.
It wears slings, similar to the suspenders on DIO's pants.
Befitting its name, Gold Experience is portrayed in most media featuring it in a shade of yellow.
Gold Experience doesn't have any personality to speak of and follows its user's commands without manifesting any will. Its Stand Cry (seemingly communicated by itself or by Giorno, alternately) is "Muda muda muda~!", like DIO with The World.
Unlike Star Platinum or Crazy Diamond, Gold Experience is not particularly strong. Despite this, it is rather fast and though an individual punch from it has roughly the same force of an ordinary man's, it can still launch a barrage of them. Gold Experience does, however, possess a very versatile power.
Gold Experience can endow anything its fists touch with life, which translates into a variety of different effects.
This ability's most featured use is converting inorganic objects into living organisms, be it an animal or a plant. For instance, it can transform a piece of luggage into a frog or a lighter into a rose. The lifeforms can persist over a long time and even a significant distance from Giorno. He can also freely cancel it and return an object to its original inorganic state.
The speed of the transformation varies wildly, depending on the desired form: an object morphing into a plant is always shown to be fast, but animals generally take more time. Thus, transforming parts of a helicopter into a tree is nearly instantaneous and violent enough that the branches can burst through metal, but transforming a rubber life saver into a fish takes a noticeable amount of time. Giorno has also instantaneously transformed drops of his blood into a swarm of ants, suggesting that the transformation time is proportional to the complexity of the life form he creates.
Giorno frequently produces small life forms (frogs, snakes, flies) and plants of which he has no control. Thus, when he creates an animal, he has to guess what the animal is likely to do in order to take advantage of it. Since the animals do not always act the way he predicts, like when a snake accidentally burns itself on a lighter, using them can prove detrimental. If living conditions are absolutely unsuitable, such as temperatures of around -100°C, then Giorno cannot transform objects into lifeforms.
Initially, when any of the created life forms were attacked, the damage would be reflected back at the attacker. For instance, Luca had tried to smash a frog with his shovel only for his head to be bashed instead. The transformation was also originally portrayed similarly to a fetus growing into an organism, but was eventually finalized as an object molding into Giorno's desired life form.
Gold Experience's ability can also be applied to living individuals, causing their thought processes to greatly accelerate. When Bruno Bucciarati was hit by one of Gold Experience's punches, his consciousness accelerated to such a point that he perceived everything else to move slowly. However, his body did not follow the surge of speed and could hardly move. While it heightens the senses of its victims as well, it also means that the then-defenseless body will feel a much more acute and intense pain over a much longer period of time when injury is taken, usually from Gold Experience's own punches.
Though only shown once, Gold Experience can also speed up an already-existing life form's life through its ability. Thus, he caused a tree to wither and expire immediately as a result of a greatly shortened lifespan.
Also shown once is its ability to even clone organisms. During Bruno's fight against Diavolo, Giorno recreates Coco Jumbo from afar, using its Stand ability to temporarily trap Diavolo inside the turtle.
Flesh and Organ Creation
Inspired by Baby Face's ability to transform body parts into inert cubes, Giorno discovered that he could do the reverse and create singular body parts and organs out of inorganic matter. Thus he is able to heal gruesome wounds through various means. In one instance, he transforms bullets into the very flesh they pierced and grew back one of his hands out of a brooch.
Thanks to Gold Experience's mastery over life itself, Giorno can sense life. Giorno himself claims that life energy to him exists in "clusters". When he touches someone or something, he can sense other lifeforms from within, allowing him to check if someone is alive or even determine how many souls there may be inside an individual. He also planned to track Diavolo by planting a brooch given life on the latter to sense it from afar and stalk the Boss.
- Taking into account Stands up to Vento Aureo, Araki lists Gold Experience as his favorite in terms of design. Along with the ladybug motif, he decided against pupils in order to make it seem more mysterious.
- According to JOJO A-GO!GO!, Gold Experience's final barrage on Green Day was the first time in shōnen manga history that a "seven page beatdown" was featured.
