Chariot Requiem is the
Polnareff ends up in the body of a turtle, and even though he no longer has a stand (it is operating on its own) he can still see stands. His lack of having a stand is also the reason he was able to grab the arrow at the end of episode 35 of Golden Wind.
During Chariot Requiem's switching of souls, Coco Jumbo's is transferred into Jean Pierre Polnareff's body where he dies as the body was seriously injured. Polnareff would later permanently stay in Coco Jumbo's body, having his soul trapped in Mr. President as a ghost.
Summary. Short summary describing this character.
Black Polnareff is one of the few characters in the JoJoBA universe who wielded 2 Stands at the same time. After Chaka was defeated, Polnareff took the Anubis sword and went for a haircut. There, the barber, Khan, was possessed by the sword and was defeated by Jotaro.
This ability's drawback seems to be Polnareff's inability to see through Silver Chariot's eyes. Polnareff is able to shed Silver Chariot's armor in order to gain more tremendous speed (enough for afterimages to appear), but doing so renders his Stand more vulnerable to attack as a trade-off.
Polnareff died shortly after the arrow pierced the original Silver Chariot, and, as a result, the Stand survived and moves on its own (much like Notorious B.I.G).
Most likely not at first. I'm sure he'll find out at some point though, but there is no telling how Polnareff will react really, I can only guess, and my guess is that, while being shocked, he would not judge Giorno for that. Afterall he came to know Gio prior to knowing this about him.
In addition, Dio gained access to a second stand through the use of Jonathan's body; this unnamed stand bears a resemblance to Hermit Purple of Joseph Joestar, and has the ability of divination.
Gyro also has two stands of sorts. The first of this is Scan, an eye that appears on his Steel Balls when Gyro has the right eye of the Saint's Corpse. Using it, Gyro can see even when his eyes are ineffective and even have x-ray vision.
He has his stand, named 'The World', and also the stand he gained from Jonathan's body, which doesn't have a name, but operates similarly to Joseph's Hermit Purple.
It's too risky: Giorno was able to heal his own body and transfer his consciousness back because he used his own stand to do so. Either Gold Experience Requiem can't transfer a second party's soul between bodies or they aren't willing to risk the possibility that Polnareff's soul would vanish in the attempt.
Jolyne, Jotaro, Hermes, and Anastasia all perish during combat with Pucci. Because they're dead, they're affected by the accelerated time, and it's assumed their bodies crumbled into dust. So, in the next universe, we see two doppelgangers of Jolyne and Jotaro, but it's not actually them.
Giorno possesses a Stand known as Gold Experience (ゴールド・エクスペリエンス, Gōrudo Ekusuperiensu), whose primary abilities are to give life to nonliving things, which is mostly used to turn inorganic objects into living organisms, and creating body parts, acting as a healing ability.
Is Killer Queen BTD a requiem stand? No, all requiem stands that we've seen have change their physical appearance. Araki might have been experimenting with requiem (or something like it) in part 4. Why else would kira have developed this ability by being stabbed.
For as powerful as Chariot Requiem is, it does have a critical weakness. If anyone looks at Chariot Requiem, they may notice that its shadow will always be opposite to the observer, regardless of any ambient sources of light like the sun.
Going by the Timeline of the series, Anubis is the very first Stand to appear chronologically in history due to it having been around for 500 years. This also makes it the oldest known Stand in the series.
Pucci wields three Stands throughout the story, those being Whitesnake, C-MOON, and Made in Heaven.
The second Diego's Stand, THE WORLD, is almost identical to DIO's The World: A powerful, humanoid Stand capable of stopping time for ~5 seconds.
As of now, fans know that Gyro was a king who served as the founder and ruler of NGL. On top of this, Gyro controlled the black market drug trade that operated beneath the surface of NGL. When the chimera ants invaded NGL, Gyro was defeated and transformed into an ant by the Chimera Ant Queen.
But is there any connection between Hamon and Stands? Hamon and Stands do not share a direct connection. While Hamon is an advanced development and manipulation of the human breath, Stands are the product of an organism's mental fortitude activated naturally or through a catalyst.
Remember when Joseph and Avdol meet Jotaro in jail and told him that Stands were a manifestation of life force? That's the same principle of hamon and that's the reason DIO isn't immune to them.
Hermit Purple is known as the 'Hamon User's Stand,' since DIO is able to use a variant of Hermit Purple due to him being in Jonathan's body. This is also because Araki commented that if another Stand User had met Joseph or Jonathan, they would appear to them with the purple vines surrounding them.
The reset caused by Pucci's Made In Heaven made it possible for Araki to wrap up the story of one universe and then start anew with an entirely different universe. So, keeping Giorno out of action was the sensible thing to do as it allowed Araki to try out new things.
Gold Experience Requiem is undoubtedly the strongest Stand in the history of JoJo's Bizarre Adventure due to its power to reject those from reaching “the truth”, reverting everything back to zero to stop them from doing it.
