These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Although Part 3 is by far the most popular part in Japan, Western fans tend to hold it in lesser regard, considering it to not have aged as well as many of the other parts, despite (or perhaps because of) it having coined many of the tropes commonly seen in Shounen series today. Similarly, although Jotaro is the most iconic figure in the series in Japan, other fans perceive him as bland, uninteresting, or even downright unlikeable in comparison to most of the other protagonists.
In addition, although Part 5 is also wildly popular in Japan, getting its own video game adaptation and being the most popular among the Doujinshi community, many non-Japanese fans actually regard it as one of the worst ones and see it as plagued by a large number of problems, such as excessive Monster of the Week fighting, a bland and uninteresting protagonist (though poor translations may be partly to blame), careless dropping of bridges and established abilities, and an ending that reeks of Deus ex Machina, even by Jojo standards.
Archive Panic: Just try and recount everything from all the arcs in time order.
In Part 2, Joseph suggests the completely reasonable proposal to stop the villains' plan by destroying the MacGuffin they're chasing after, the Red Stone of Aja, which Lisa Lisa already possesses. To keep the story from ending prematurely on such a boringly mundane note, Araki has Lisa Lisa explain that according to a legend, without the Stone, the Pillar Men would ultimately be impossible to defeat. One can argue that this is true because Ultimate Kars is only defeated due to his own Aja-amplified Ripple causing a volcano to erupt, but that would require one to forget that the Red Stone of Aja is the only reason Kars became the Ultimate Lifeform in the first place, and that he was moments away from being killed by Joseph and Stroheim before he transformed.
Subverted when you realize that Kars had intended to kill Joseph and Lisa Lisa with his army of vampires as soon as they entered his chambers. The only reason that they'd even gotten to have their one on one duels instead is because Lisa Lisa was able to use the Red Stone as a bartering chip, which they then had to prove was real before said duels. Additionally, the Red Stone's continued existence caused Kars to act in a more direct fashion. Without its presence, he likely would have gone into hiding until he could find a substitute, possibly creating an even larger vampire army.
Kars suddenly getting the mask with the stone inserted without anyone knowing, just as he's about to be fried by ultraviolet rays. The anime alleviates this somewhat due to a bit of Adaptation Expansion in which Kars makes a seemingly futile leap after first landing on the spikes, giving him a more plausible opportunity to grab the mask and put the jewel in.
In Part 3 Avdol surviving out of nowhere. He was killed several chapters ago with the rest of the cast confirming his status. Now, when it is revealed he is back the cast tries to make it look kept his identity a secret.
Awesome Art: While every part has its fair share, Steel Ball Run shows a noticeable increase in quality after the series was changed from a weekly to a monthly release, to the point that it exhibits some of the most beautiful art in recent manga history.
Awesome Ego: Many characters in this series are completely aware of how Crazy Awesome they are, with Dio Brando and Joseph Joestar being the two greatest examples.
Which part is the best part? The fanbase really can't agree on this one.
The 1993 OVA of Stardust Crusaders, which started In Medias Res and was a Compressed Adaptation that cut out most of the fights and humor of the original. Did it butcher the source material by taking out what made it popular in the first place? Or is it entertaining Fanservice to manga fans who just want to see their favorite fights animated? Are the changes to some of the fights and Dio's character design an improvement or do they make things worse? Or is it all just So Okay, It's Average and only worthwhile for serious fans?
The infamous torture scene in Part 5. Was it a tasteless moment that made it impossible to sympathize with the main characters? Or was it just a natural part of them being gangsters?
The ending of Part 6 is also very polarizing due to effectively resetting the entire Jojo universe and starting a new continuity.
In Battle Tendency, after Wamuu released his masters Kars and Esidisi from their emprisonment, Kars accidentally steps on Wamuu's shadow. This caused the latter to instinctively attack the former. He quickly apologizes to his master and Kars does the same. That being said, stepping on Wamuu's shadow comes across as a Chekhov's Gun, but no. It's never mentioned again.
In Steel Ball Run, any time that Gyro comes up with a gag, odds are it's gonna be a weird non-sequitur joke that Makes As Much Sense In Context and is never alluded to again.
Dio Brando. He has no compunctions with forcing people to do his bidding, and if they do that, it's no guarantee of survival (think the rich man who drives him around in Part 3). His shadow also looms large over all antagonists that follow him, with all of them being connected to him in some way, and he's directly responsible for the events of Part 6, where he corrupted a Priest into carrying out a plot that would allow Dio to remake the world in his own image by proxy. He used his time-stopping stand to force someone to eat a dead cat and stab someone else in the face — and he did this just because he could. In Part 1, after being adopted by Jonathan Joestar's father, he proceeded to make Jonathan's life a living hell for no adequate reason. He beat up Jonathan, humiliated his girlfriend, burned his dog alive, tried to poison his father, and forfeited his humanity to become a nigh-immortal vampire. Dio then embarked on a killing spree across London, with his atrocities including cornering a young woman, who begged Dio to spare her baby. Dio agreed, promising not to kill the baby, but killed the woman only to revive her as a zombie. True to his word, he left the baby, but watches as the zombified woman proceeded to eat her own child in front of him. He refused to die after being defeated, with his severed head returning at the very end to attack the cruise ship Jonathan and his new wife are on, thus sinking it, leaving few survivors. Jonathan drags him to the bottom of the sea with him, finally killing Dio... until he returns 100 years later, using Jonathan's corpse as a body for his severed head. Even though Dio had a hideously abusive father, his Freudian Excuse isn't nearly good enough to excuse his barbaric behaviour.
Cioccolata. For starters, his back story involves him torturing old people to death while maintaining a guise of being a good samaritan. When he starts fighting the heroes, he makes sure that he starts horribly killing the innocent people in the village just for fun. His Stand, Green Day, which causes a fleshing-eating mold to quickly devour its victims, works when people are at a lower altitude than him, so what does he do? He gets on a helicopter and flies above Rome to kill as many people as possible. It says something when even the Big BadDiavolo, a man who would kill his own daughter to protect his identity, is disgusted by him. Thankfully, Giorno proceeds to give Cioccolata the biggest and longest beatdown in the series, which sends him flying into a garbage truck with "Combustable Trash" labeled on the back.
The whole series. This is a manga which turned Rock-Paper-Scissors into an actual power and then used it for an epic battle to boot, complete with air jousting. Then there was that life-or-death game of catch in Part 6.
In Part 1, Dio wants Jonathan's body. In order to "live gorgeously forever".
In Part 2, two of the Pillar Men actually become engaged to Joseph, with rings and everything. It's an engagement of Death, but an engagement nonetheless.
Josuke/Rohan is a pretty popular pairing even though Josuke doesn't care for Rohan and Word of God is that Rohan flat-out hates Josuke's guts for burning his house down. Then again, Rohan is pretty Tsundere, and is willing to endanger himself to protect Josuke against Highway Star, so there is a limit to his antipathy.
Despite Josuke being a pretty popular Jojo, having the 2nd most popular villain (behind Dio), and being one of the most popular parts overseas, Part 4 is one of the least popular in Japan (ironic since it's one of the few parts that actually engages in Creator Provincialism). However, since it's Araki's favorite section of the manga, he pushes for merchandise of it.
Meanwhile, the French are big fans of the series as a whole, despite the first translation being by editor J'ai Lu (who was notoriously bad with its manga imprint, not only having usually borderline blind idiot translations, but also using extremely cheap paper and ink). Araki was even invited to do a fine arts exhibition in 2009 at the Louvre (which houses the Mona Lisa as well as countless other priceless works of art).
Genius Bonus: Whitesnake/C-Moon has "GΔCT" written all over its body to represent the four nucleobases that bond DNA. Astute geneticist readers will notice that the delta sign (Δ), where A should be, is the sign of gene deletion aka a missing genome, foreshadowing that Whitesnake/C-Moon aren't the "complete" forms of Pucci's stand.
Phantom Blood generally came across as being a typical melodrama told in manga form, with nothing particularly "bizarre" about the titular adventure other than Speedwagon's somewhat anachronistic name and his buzzsaw-hat. Then Dio turned into a vampire, and at that point all bets were off. The beard-growing continued with the introduction of the Ripple fighting style, which led to some particularly clever and out-there battles.
Battle Tendency was where the series went from unintentionally over-the-top, to not only embracing it, but cranking it Up to Eleven. It's also where the series' penchant for fights based more on intelligence and clever tricks truly started. Granted, there were a few moments like that in the previous part, usually revolving around Dio, but the sequel went full bore on it by turning the protagonist into a full-on Guile Hero and making almost everyone he goes up against not just Nigh Invulnerable, but extremely clever as well.
In an interesting parallel, JoJo's Bizarre Adventure: The Animation also got noticeably better during this part of the adaptation due to an increase in budget, allowing for more character movement, and a larger number of episodes dedicated to it, allowing for better pacing. It allowed the viewer to feel more emotionally invested in the characters.
Stardust Crusaders, when Stands were introduced and replaced the Hokuto Shinken-esque style of martial arts used in the previous parts, is considered by many to be the point when the series really got interesting with Puzzle Boss fights becoming the conflict of choice.
A lot of people who read Diamond Is Unbreakable find that Yoshikage Kira's introduction halfway through the story arc allowed that part of the series to really come into its own. This is particularly because of the later battles in the arc, which are cited as some of the best in the manga.
Grew another layer of hair midway into Steel Ball Run, with the Shōnen-to-Seinen shift resulting in pronounced Art Evolution and a move from fun action stories with occasional heavy moments to a serious character-driven and plot-heavy drama.
Harsher in Hindsight: A week or two after Robin Williams dies, the Judgment episode of Stardust Crusaders airs in Japan. It features a boisterous, Large Ham of a genie who even sounds somewhat identical to the character from the Disney film. Keep in mind that this particular chapter was published before Aladdin came out.
Hell Is That Noise: "Abyss" from the 2012 anime is this in music form, which appropriately starts playing the first time the Pillar Men show off their Body Horror skills.
In Part 1, Erina Pendleton has her Sacred First Kiss stolen by Dio Brando and is beaten mercilessly by him. She can't do much to avenge herself. In Part 7, Lucy Steel, the former Lucy Pendleton, personally causes (alternate universe) Diego Brando's head to explode. The best part is, she's not all that much better in the fighting department.
During his fight with Kars, Joseph sets up a dummy with a henohenomoheji face on it as a decoy. One of the most famous roles of Kazuhiko Inoue, Kars's VA, is Kakashi in Naruto, whose namesake refers to scarecrows which in Japan are often marked with a henohenomoheji on their faces.
During the fight with Hanged Man in Part 3, Polnareff thinks that it attacks from "A world inside the mirror". Kakyoin dismisses it, saying that there is no such thing as a world inside a mirror. Cut to Part 5 where Illuso and his Stand, Man in the Mirror, attacks by dragging people into a world inside a mirror.
Terence reads Jotaro's mind during the baseball videogame match to counter his moves, but suddenly Jotaro's character starts doing moves that he didn't intend to. When Jotaro wins, it is revealed that he had secretly swapped controls with Joseph. Years later, one way to harm mindreader Psycho Mantis in Metal Gear Solid is to confuse him by putting the controller on the P2 port.
The Lovely Bones: Serial killer, victim trapped between worlds. Sounds like Part 4. Alas, it has no punches.
The villain of Part 4: a bishonenserial killer looking to make the world adapt to his will. His name: Kira. Just as planned...and just like the latter Kira, he is also defeated by announcing his victory a little too early.
In the very first chapter of Vento Aureo, the first person Koichi stumbles upon after landing in Italy turns out to be Giorno. Romi Park first voiced Giorno in the PS2Vento Aureo game, and then she voiced Koichi in All-Star Battle.
The Phantom Blood ending. Two lovers are boarding a ship to New York? Check. Something (or someone in Jojo's case) wrecks said ship? Check. The man sacrifices himself in the dire situation so that the woman can survive? This played out similarly to the Titanic film 10 years later, only without the zombies led by a vampire with eye beams.
"KOICHI REALLY STEALS? NO DIGNITY" was already one of the more popular and quotable lines from Duwang. Then this happens. Perhaps Araki has a time-travel stand.
HSQ: Due to the author's don't-show-everything-at-the-start storytelling style and... imagination... the series continually throws ever more crazy abilities at the reader.
Part 2 near the ending: Nazi-eating, Vampire Squirrels grown out of the shoulder of Kars.
Start from chapter one of Stone Ocean — and you'll still go "WTF???!!!!" trying to figure out the freaky basis of the latest enemy Stand!
Whitesnake, a Stand who can open your head like it was a CD player and take out CDs containing either your Psychic Powers or your soul.
It Was His Sled: Dio. You'd have to live under a rock in another universe to not know that he was reduced to just a head, then kills Jonathan and steals his body. Also, he's the Big Bad of Stardust Crusaders and can also stop time. It sort of makes all the buildup leading to the reveal for naught.
Jonathan's life became horrible when Dio entered the scene. He loses his dog, his girlfriend, and all his friends. He somehow makes it to adulthood without a single noticeable emotional scar.
Joseph's life was also bad, thanks to Dio's influence. His father was killed by one of Dio's surviving zombies, his mother had to go into hiding after killing that zombie, he grew up a lonely child, and it's heavily implied his colorful personality developed as a defense mechanism, his best friend was killed by a near immortal vampire-like being, by Part 3, most of the people who had been his allies have died, his daughter was on the verge of death due to Dio's influence, Dio even succeeded in killing him for a time, and it takes nearly bleeding himself to death before his attempts to bond with his son work. Yet, he's still one of the more optimistic JoJos.
All the shit Jolyne goes through at the beginning of Stone Ocean. It makes her determination to save her father all the more heartwarming.
Just Here for Godzilla: In Part 3, people most remember the Jotaro vs. Dio, fight as it is very unique and epic. Especially true for the 1993 OVA; while people's opinions vary on whether it's a good adaptation as a whole, nearly everybody agrees that the final episode of Jotaro and Dio's fight was pulled off near-flawlessly and a must-see.
Launcher of a Thousand Ships: Dio, natch. Helps that practically every other scene he appears in is positively dripping with Ho Yay and that he appears in so many parts, whether directly or indirectly.
Joseph, for similar reasons.
LGBT Fanbase: Unsurprising since the entire series is positively dripping with Ho Yay, and appeals to a wide spectrum of queer audiences. The first parts are filled with Tom of Finland-esque manly designs popular with Bara Genre fans, while later ones appeal to fans of Bishōnen. On the female side of things there's Part 6 which takes place in Girls Behind Bars and includes strong, sometimes even Butch Lesbian looking women in its cast, as well as Scarlet Valentine in Part 7 who is openly Bi the Way.
Love to Hate: Dio Brando. He is an evil son-of-a-bitch, and he comes with a convenient Freudian Excuse for apologists to latch onto, but he's so damn cool that he is easily the series' most popular character precisely because of it rather than in spite of it.
Magnificent Bastard: Dio in Parts 1 and 3, Kars in Part 2, and Funny Valentine in Part 7. And for a rare protagonist example, Joseph in Part 2.
Noriaki Kakyoin wants Jotaro's mom. He wants your mom. He wants all moms.
Dio is this both in and out-verse; he's Bi the Way, so he'll go after anyone. Every one of his closestminions are pretty much worshiping his feet and/or have implied to have slept with him at one point, and he's fathered at least four sons out of four random women.
Dio. In the first volume, to avenge himself from Jonathan giving him a much-deserved ass-whupping (in a fair fight, no less), he retaliates by tying up Jojo's beloved pet dog in steel wire, putting him in a wooden box, and putting the box in the Joestar estate's incinerator, so that when the butler lights it up... Plus, there's the business of the captive mother who lets herself be turned into a zombie by Dio if he will spare her baby's life...
Tarkus crushing the remains of his friend Bruford after his death and mocking his weakness, revealing that he'd given himself over to Dio's control entirely (whereas Bruford at least remained a Noble Demon) surely counts.
Kars when he goes back on his word on fighting fairly with Lisa Lisa, by striking her from behind because it was more convenient than fighting head on; not only does it reveal that he's completely dishonorable, but it besmirches the memory of his two comrades, the latter of which gave his life in a life-threatening battle moments before this.
Diavolo crosses this for Bruno when he reveals that the reason for bringing Trish to him was to kill her himself, since she was his daughter, on the miniscule possibility that people would discover his identity through her. Bruno immediately went from curious to wanting him dead.
Pucci crosses it for Jotaro when he decides to pull Dio's signature knife move on Jolyne to anger him.
Funny Valentine crosses it after trying to rape Lucy and then in Johnny's eyes when he backs out of his promise to revive Gyro when he decides to kill him.
Most Annoying Sound: It doesn't come across very well in English, but Magenta Magenta's voice is supposed to be incredibly whiny and nasal.
Johnny Joestar's scream of "I MUST KNOW THE SECRET OF THE BAAAAALLLLSSSS" is more hilarious (or ridiculous — take your pick) than the serious and emotionally impacting line it's supposed to be.
Narm Charm: All the Crazy Awesome makes the ridiculous names somehow great instead of pure corn. The manga and anime are full of constant grit and Gorn. However, take that, throw in some of Japan's best voice actors, as well as bright colors, strong art direction, and acting and narrative that is so over-the-top it's awesome, and you can see why so many are hooked.
What other series could make you take a villain dressed in hearts named Vanilla Ice with his stand Cream seriously?
Caesar's death is played for all the melodrama it's worth, especially in the anime, where they even break out the opera music. It's still one of the most tragic scenes in the series.
Hanged Man. It can attack from any reflective surface. This includes eyes..
Teranosuke Miyamoto — his powers only work on a person if that person gets scared. This is easier for him to do than you would think.
Pray to god that nobody looks at your back if Masazo Kinato's Cheap Trick is attached to you...
Polpo's shadow ability. It's to the point where he can come out of the shadows of flying birds.
It's Zucchero's sheer effectiveness with his Stand in staying hidden while attacking that makes him paranoia-inducing. It takes Moody Blues to actually find out why the rest of the team is disappearing one by one.
Squalo's Stand in the Tizziano/Squalo arc: "There's a shark in the soup!"
Going Underground/Born This Way, at least until Josuke figure out how it works. It just keeps showing up out of nowhere!
Refuge in Audacity: The sheer HSQ in the series can warrant this, whether from the characters' fabulous mannerisms, the over the top and clever powers and fights, or how much Dio can Kick the Dog.
The runaway girl/Anne from Stardust Crusaders is despised by a number of fans for serving no real purpose to the story and just for being a nuisance. Even Jotaro and the gang can't stand her and eventually trick her onto a flight back to Hong Kong just to get her away from them.
Diavolo is probably the least-liked major villain in the entire series. But rather than it due to being a Hate Sink as was intended, he is often held up as an example of how not to write a villain for reasons given such as being considered a Giant Space Flea from Nowhere, having a lame Freudian Excuse for a motive, a design so garish that it's Narmy and thus hard to take seriously, and ultimately being defeated through an extremely unsatisfying Deus ex Machina. That said, even his haters still think his final fate was undeserved.
Seinfeld Is Unfunny: This is the eighth-longest-running manga, ever, and it seems tired at points (but no less awesome) by today's standards, seeing as it invented most of the current shonen tropes. This ironically played in the 2012 anime's favor, since in these days of deeply flawed heroes, sympathetic villains and many played and subverted shonen fighter tropes, Part 1 Phantom Blood's by the book Ideal Hero Jonathan, unambiguously and Obviously Evil (yet still having some degree of complexity) Dio and many played seriously straight shonen tropes actually look fresh.
Serial Escalation: The entire series has elements like this, which only become more and more prominent with each successive installment and Stand introduced.
Although Jotaro/Kakyoin is hugely popular in the fandom, the two are not very close in the original manga, given that Jotaro does not talk much to anyone in Part 3 aside from his grandfather. In fact, their interaction in the source material is so limited that it actually leans closer to the Crack Pairing side. Much of the pairing's popularity appears to stem rather from an infamous doujinshi and Expy-ladenmanga made by CLAMP in the early 90's.
Giorno/Jolyne has a fair degree of popularity even though they've never met (despite some teasing of a cameo in Stone Ocean) and he's technically her great-great-great-uncle. Even Araki's drawn art of them getting frisky.
Superlative Dubbing: In contrast, opinions of the initial release of the JJBA The Animation: Stardust Crusaders dub have been mostly positive, with even non-fans judging it as So Okay, It's Average at worst.
Song Association: Thanks to the new anime series, many an anime fan automatically correlates Yes's classic prog-rock song "Roundabout" with Jojo. Thanks to Stardust Crusaders, the same has happened to the Bangles' "Walk Like an Egyptian".
The Pillar Men's Body Horror powers, Esidisi's Fingore and Santana's abilities stand out the most.
Yoshikage Kira takes hand fetishism to the extreme: he likes to sever the hands of the women he kills and treat them as girlfriends, buying them gifts of jewelry and taking them on dates before they rot away. Just...ew.◊
Just try to look at how Pesci uses Beach Boy on Mista without cringing.
The way Jolyne uses Stone Free to unravel herself is pretty cringe-worthy.
They Wasted a Perfectly Good Plot: Alessi from Stardust Crusaders had a Stand that could turn people into younger versions of themselves. There just so happened to be a Cool Old Guy among the Crusaders who kicked a lot of ass in his youth, as documented in Battle Tendency. Too bad Alessi ended up getting pounded into hamburger by Jotaro and Polnareff before he came across Joseph. For what it's worth, Heritage for the Future explored this scenario with Jojo's Story, though it was more of an Excuse Plot than anything.
Values Dissonance: Giorno and Bruno are involved in the mafia, which is guilty of a wide swath of terrible deeds, such as the murder of innocents, blackmail, extortion, and assassination. Yet for them the big crossing of the Moral Event Horizon comes from gang members selling drugs to children. While most Westerners can agree that it's terrible, they wouldn't consider it as so much necessarily worse than those other things combined either. Part of this can be explained by Japan having a much stronger stigma against drug usage than most countries in the West, to the point that even minor marijuana offenses face steep sentences.
Vento Aureo is probably the worst in this regard, occurring before the shift to a more mature seinen magazine—each and every arc in the series (which is to each of the dozen conflicts with stand users) centers around some aspect of bloody, gory, painful body horror. The next part, Stone Ocean, is also pretty bad with the gore. And has prostitutes, vibrators as currency and people exploding into snails.
The Woobie: Both protagonists of JoJolion, Yasuho and Josuke, have very compelling personal conflicts—Yasuho's terrible mother and Josuke's lack of family—that cause them considerable angst. The poor guys are just constantly reminded of the shitty aspects of their lives. Yasuho even breaks down crying because of the stress and Josuke tears up a little when he sees a happy family playing around and is reminded that absolutely no one came to look for him when he went missing and lost his memory. The latter is also in the context of the Japanese natural disasters of 2011, wherein it is pointed out that families came together to support and protect each other in that great time of need.
Polnareff gets it pretty hard in Part 3 when he's not just being the designated Butt Monkey. Aside from the whole dead sister thing, how many people have one of their friends die to protect them twice?
