Giorno Giovanna/Abilities and Powers

Stand
Gold Experience is one of the most versatile Stands in the series. It has the ability to create and manipulate life, which Giorno most often uses to produce plants and small animals. Both can be used for a variety of purposes ranging from disguise to tracking origins. Gold Experience Requiem is obtained after Giorno pierces Gold Experience with the Stand-creating Arrow. It has the ability to turn the opponent's willpower and actions to zero. Whoever is killed by Requiem will also "have his death turned to zero", forcing him into a death loop for all eternity. Gold Experience was also pierced by the Arrow during Entering the Gang, Part 4 when Giorno is attacked by Black Sabbath but it is unclear whether this is an oversight on the part of Araki, or Requiem was possible then, but only realized when given a reason to manifest.

Personal
Intelligence: Giorno is a very competent tactician. An observer by nature, Giorno likes to assert his opponents' abilities and plans before acting. He then uses his observations to probe for any weakness of their part and predict what they will do, often returning their moves against them. Using his Stand with remarkable imagination, Giorno gives himself a wide range of possibilities, the exploitation of Gold Experience's power and the characteristic of animals he transforms objects into allows Giorno to, among others, reposition himself quickly, or tracking his opponents. Moreover, he is good at using his environment to his advantage. Giorno is quick on his feets, and is able to formulate plans on the spot.

Giorno has shown himself adept at cooperating with other Stand users with maximum effectiveness, particularly Guido Mista with whom  he is close. Giorno is able to exploit his partner's power almost as effectively as his own, taking account of their precise abilities and using them in his tactics. Most basic of all is transforming Mista's bullets into other lifeforms to take his enemies by surprise and multiply Giorno's effective range.

Despite seeming to have a reckless side, notably infecting himself with Purple Haze's virus, Giorno is a very careful person, constantly warning his partners of their impatience. He always has backup plans and makes sure his enemies are eliminated. While appearing as reckless, he in fact takes calculated risks.

Knowledge: Giorno is very knowledgeable in biology. His encyclopedic knowledge of fauna and flora allows him to transform objects into the lifeform most suitable to his goal, as well as deducing his enemies' powers.

Charisma: Giorno is a charismatic individual, able to sway people to his side easily. His habits of observing his peers allow him to then deduce the best way to impress them and make them an ally.
