JoJo's Bizarre Adventure

JoJo's Bizarre Adventure is manga series written by Hirohiko Araki. The manga is separated into nine published parts, with the ninth currently ongoing Starting in 2012, the series has been adapted into a TV anime by David Productions, and so far has adapted five seasons up to Part 6.

Summary
JoJo was serialized in Weekly Shōnen Jump from 1987 until 2004, then to monthly Ultra Jump from 2004 to present.

There are 131 volumes currently published in Japan. English publication started in 2015, with only four out of the nine parts currently completed. The fifth and sixth parts, Golden Wind and Stone Ocean, are currently being released synchronously. Part 5 volumes have been serialized since August 2021, and Part 6 chapters have released weekly since January 2022.

JoJo is separated into two continuities, one that released from 1987-2004 that stretched across six of the nine parts, and the other from 2004-present day that go across the seventh, eighth, and ninth parts.

The series is an anthology that follows a new protagonist with new supporting allies and villains in each part. The protagonists of the first eight parts are all nicknamed "JoJo," and are part of the extensive Joestar lineage. These characters, in order of appearance, go as follows:

In the original continuity: Jonathan Joestar, his grandson Joseph Joestar, his grandson Jotaro Kujo, illegitimate son of Joseph, Josuke Higashikata, son of Dio Brando, Giorno Giovanna, and daughter of Jotaro, Jolyne Cujoh.

In the second continuity: Johnny Joestar, his complicated ancestor, Josuke Higashikata, and Johnny's great-great-grandson, Jodio Joestar

In summary, JoJo's Bizarre Adventure is about the strange and bizarre adventures that follow the Joestar bloodline, as they defeat enemies with the use of supernatural abilities such as Hamon, Stands, and Spin.

Phase One: Dio's Curse on the Joestars (1987-1992)
The original trilogy, ending with the final confrontation against DIO. It begins with three different JoJo’s, who would– in some sort of way– all be descendants of each other, and that their lives would be linked by a common curse, started by the vampire Dio.

Part 1: Phantom Blood (1987)
The first part of JoJo, set in England 1880, follows Jonathan Joestar in his training of Hamon in order to defeat his evil adopted brother Dio, who is transformed into an immortal vampire by an ancient Stone Mask. Jonathan uses Hamon, an ancient breathing technique passed down through the Zeppeli family, to defeat Dio and his horde of zombies and other vampires. At the end of the story, Jonathan sacrifices himself to defeat his adopted brother once and for all, helping his pregnant wife to live another day.

Joseph comes face-to-face with the creators of the ancient Stone Mask, the Pillar Men, who are much stronger than a typical vampire. He must defeat this ancient race of super-beings with the help of Caesar Anthonio Zeppeli, Lisa Lisa, and Rudol Von Stroheim before they can recover the Red Stone of Aja and become rulers of the world.

This part introduces the concept of Stands, supernatural abilities that manifest as the form of the user's fighting spirit. Because DIO has been revived, he has unlocked his own Stand, giving everyone in the Joestar family an ability as well due to their psychic connection to Jonathan's body, which DIO now inhabits.

Giorno joins Bruno Bucciarati, Guido Mista, Leone Abbachio, and the other members of Passione, attempting to take down the mob's illusive boss: Diavolo.

Premise
The Stand Arrow that appears in Part 5: Vento Aureo, stylized with a beetle design not present in other Stand Arrows, is a special arrow with different powers from the regular Stand Arrows. It is dubbed the "Requiem Arrow" because of its apparently unique ability to evolve existing Stands into Requiem Stands.

This is a list of several arguments I have heard in favor of this theory:


 * The stylized beetle arrow is the only one of its kind, and due to its unique design it is implied to be special in some way.
 * The beetle arrow has "more virus" in it that gives it its special abilities.
 * During the Black Sabbath Arc, Giorno's hand is stabbed with a Stand Arrow of the typical design, and Giorno does not unlock Gold Experience Requiem.
 * The "Requiem Arrow" has the specific ability to dominate people's souls, and that Polnareff makes this distinction in his flashback revealing Chariot Requiem's first appearance.
 * Giorno acknowledges, when he first sees the "Requiem Arrow" that it is "similar" to the arrow he encountered fighting with Black Sabbath, and therefore implies it is special.

Rebuttal
There's a lot to tackle here so strap in. Before I really get into it, I want to preface this argument by noting that nothing is confirmed if there is no specific written word about the matter. Meaning, unless someone in Part 5 or Araki himself noted the difference between the beetle arrow and the others, then everything for either side should not be taken as fact. This just so happens to be my current stance on the matter.

My opinion, which I have held since I first watched Part 5, is that all the arrows, beetle or not, have the same ability. The thing that differentiates Requiem Abilities is when a Stand Arrow pierces a Stand, rather than a person. On a slightly off topic note, arguments could be made whether or not Killer Queen Bites the Dust is a Requiem Stand, but the distinction there is that the Stand Arrow stabbed the user, rather than the Stand in this instance.

The most common argument I have found in favor of the Requiem Arrow is that Araki specifically differentiates this arrow from the other ones because of the beetle emblem on it. My argument is, if there is a difference between the two, why isn't it ever specifically mentioned? Araki is very explicit in his writings, and more often than not, he explains to us a plot point several times over. He rarely ever leaves things to mystery, which is why I highly doubt he would leave something so important about the details of the mcguffin for this part out of the story entirely. I don't personally believe the beetle emblem has any other significance other than the fact that Araki wanted to stylize the focal point of Part 5 to give it a special characteristic to differentiate it from the arrow in Part 4.

Another thing I see a lot is that the beetle arrow has "more of the Stand virus in it" compared to the other arrows, which gives it its Requiem-giving abilities. This is absolutely ludicrous, because that's not only not how viruses work, but makes no sense at all. Going back to the point I mentioned before, if there really was "more virus" in this arrow stored in that beetle, I feel like that would be a pretty important thing to mention. People have brought up several character quotes from the series, such as Giorno mentioning that the beetle arrow is "similar" to the one he saw during the Black Sabbath fight, but that, I feel, isn't evidence enough that it's special in any way, it just proves that yes, it looks very different from the other arrows, but besides that it doesn't mean much.

Another quote that gets passed around a lot is Polnareff mentioning that "If this arrow were to be used by someone with power... That person would be able to dominate the souls of all life!" The argument here is that the Requiem Arrow gives all Stands the ability to manipulate souls. This is one of the strangest arguments I've seen arguing for the existence of the Requiem Arrow, since only one of the two Requiem Stands we ever see has the distinct ability to manipulate souls. Gold Experience Requiem is never explicitly stated to have this ability, and even when you analyze it, it really seems like a reach. Another thing to note is that Enrico Pucci (and by extension Weather Report,) also get their Stands from a beetle arrow, as shown in the flashback in Stone Ocean Chapter 127. Whitesnake, Pucci's Stand, can absolutely manipulate souls, but the same can not be said about Weather Report, which leads me to chalk that up to coincidence and discredits the theory. What Polnareff is referencing in that quote is the fact that his specific Stand, when evolved into Requiem, has the ability to manipulate souls. The same cannot be said for GER, so it seems like Polnareff was only speaking on very limited knowledge at the time, seeing as Chariot Requiem was the only Requiem Stand he has every truly seen (as far as we know.)

The final piece of evidence they have against me, which I also think is the hardest to debunk, is the fact that Giorno's hand is cut open with a regularly designed arrow back in the Black Sabbath fight, and no Requiem ability is drawn out. I honestly cannot give a concise reason as to why this happens, as this is the most damning piece of evidence against me, but I have a few theories of my own. One is that, if you pay attention, Giorno's hand starts emitting smoke after he is stabbed. This is a pretty minor detail, and it isn't proof of anything, but it makes you wonder why this detail was ever added. When Koichi gets stabbed with the Stand Arrow in Part 4 he doesn't emit smoke at all, and I think that the difference here is that Gold Experience was stabbed instead of Giorno, and GER was going to be awakened, but hadn't the time to because of the circumstances. The smoke being indication that the ability was going to be drawn out, but wasn't.

Another theory I have about the situation is that the Stand Arrow was in possession of Black Sabbath at the time, and was not meant to choose a host and become a Requiem Stand. The trend with the two Requiem Stands we've seen is that the Stand Arrow has always been incorporated into its design, whether its on GER's forehead or being held in Chariot's hands. In both cases of these Stands evolving, the Arrow was in the position to become one with its new host. In the case of the Black Sabbath fight, the arrow was already in possession of BS, so it transferring into Giorno to form GER couldn't be possible unless the arrow was separated from BS.

The final idea I have, and this is the least credible, is that the Arrow had just yet to choose Giorno in that moment to evolve his Stand. The arrow has been shown on multiple occasions to be sentient, first we see this happen in Part 4 when it literally points to its next victim while in possession of Yoshihiro Kira, as well as when the arrow literally climbs up Yoshikage Kira's arm when giving him Bites the Dust. It is also flat out said by Diavolo himself that fate chooses the arrow's next host. My theory is that Giorno was not fated to unlock Requiem in that moment because he was fated to unlock it later in his battle with Diavolo. Why didn't he get GER at that very moment? Because otherwise there would be no plot.

Also... Araki might not have written Requiem Stands into the part yet... but that isn't a good argument...

Premise
In the final battle between Gold Experience Requiem and Diavolo in the fifth part of JoJo's Bizarre Adventure: Golden Wind, Gold Experience Requiem (often shortened to "GER,") deals a final blow to the boss of Passione, which causes him to perceive himself in the third person in a seemingly infinite loop. We are then shown that Diavolo begins to experience his own death over and over again. Through context given to us in between chapters and through descriptions from characters in-universe, we are specifically told that GER causes Diavolo to experience an infinite amount of deaths, and that he will "never reach the truth" of how he really died as a punishment for his sins.

The premise of this argument is that if Diavolo dies in any fictitious event conceivable (or inconceivable,) then because he is stated to die an infinite amount of times, then that automatically means that this event is canon to JoJo's Bizarre Adventure lore.

This is a list of several arguments I have heard in favor of this theory:


 * The Infinite Monkey Theorem: Wherein if a monkey were to type on a typewriter randomly for all of eternity, he would write every finite text an infinite number of times. The idea is that if Diavolo dies an infinite number of times, then any conceivable scenario in which he dies becomes canon merely because it is possible.
 * After being shown the death montage, Trish remarks that she can still feel that her father is alive, but Giorno reassures her that he has been dealt with.

The premise also indicates that because the deaths happen they are canon, implying that the deaths occur on some form of physical plain within the JJBA universe.

Rebuttal
This one is actually a little more easy to rebut than the last topic. Most of my points come down to semantics and common sense, and I'm gonna mix in a little bit of my own headcanon just for safe measure. Like the last Requiem ordeal, the exact answer isn't totally clear in the manga either, so I'm gonna have to do my best to explain it using as much canon material as possible.

Basically, when it comes down to it, the premise is just straight up wrong, ignoring the fact that it totally misunderstands how the "death loop" works in the first place. My first point, which I think is easiest to get this out of the way, is that the death loop does not occur on any physical plain of reality. This is a SUPER common misconception, that I guess JoJo fans seem to just assume since we're not directly told that it isn't the case. No, Diavolo's deaths do not occur in some alternate universe, or a collection of them, nor does he get displaced throughout the world in order for him to die. How do I know this? Literally just common sense. Nowhere in GER's power-set does it allow for anything of this sort to occur. GER is not omnipotent, it cannot create alternate pocket dimensions just to kill one guy forever, and no it does not displace Diavolo throughout earth to kill him in random locations. That is just not what the Stand does.

The next thing that's pretty important, and actually stands alone regardless of the last point, is that just because something has infinite possibilities, doesn't mean that it accounts for every possibility. The easiest way to describe this is with this allusion: There are an infinite amount of numbers between 1 and 2, but none of them are 3. To put it simply, just because Diavolo dies an infinite amount of times doesn't mean it's automatically possible for every single inconceivable scenario to happen. Obviously these "deaths" still have to occur within the logic of our reality.

Another thing is, and this really just comes down to semantics, is that GER specifically states that his ability is that Diavolo "will never reach the truth" of his death, and will experience infinite deaths. Those words alone mean that these deaths aren't happening in some alternate reality because Diavolo is only experiencing the deaths, rather than actually physically dying all of those times. The way I see it, (and this is where my headcanon comes in,) Diavolo's deaths flash before his eyes in the same vein as the saying that "your life flashes before your eyes" before you die in real life.

The only problem is that when we do see Diavolo's infinite deaths, Trish says that she can still feel him alive somewhere... which means that everything I've said is bullshit. I guess? I can't really come up with a counter argument for this because it just straight up feels incorrect. Everything I've said up until now is very logical and concise but this really fucking stumps me. Really, how does that make any sense? To quote the great Lucille Bluth here, "I don't understand the question, so I won't respond to it."

And that's really it. This second point given could actually work on its own to disprove the whole meme, but the first one kind of also needs to be said because this fandom is just chock-full of misconceptions.

So no, guy who's asked this question for the four hundred and trillionth time, Diavolo is not "still dying" at any point throughout Stone Ocean or any other JoJo media... He died one time, and perceived himself to die an infinite amount of times.
