Nearly every animation and every quote in the game is a reference to a specific frame or line from the manga. A fan even went so far as to make video compilations that show each individual pose in the second trailer and where it appeared in the manga: Part 1 and Part 2.
Various pairings of characters have unique battle banter for their intros and outros. Usually it's kept for characters from the same arc, but there are some cross-arc comments for those who have appeared in multiple parts.
Mirror Match battles have their own unique intros and outros, usually wondering if the opponent is the result of a Stand power.
Even the trailers themselves have exclusive references to the manga!
PV1 references many panels from Rohan Kishibe's introductory chapters, "Let's Go To The Mangaka's House!", from Part 4.
PV5 features Robert E.O. Speedwagon from Phantom Blood as the narrator. He starts saying that he can recognize a good game from a bad one by its smell (a reference to how he can recognize if a person is good or bad by their scent), uses Jonathan's Catch Phrase before the title card, and ends up "withdrawing coolly" (a reference to what he did in the hospital scene after sneaking a peek at Erina and Jonathan).
PV6 freely spoils how some key characters across the series are defeated.
Usually, a character with low health will enter Rumbling Mode, which increases their attack power and fills their special gauge faster. However, a few characters get "Resolve Mode" instead, where they can't flinch anymore, thus taking damage won't interrupt their attacks. They have reasons for getting this mode:
Giorno discovered that his stand can create replacement body parts during the fight with Baby Face, after said Stand took away 4 or 5 pieces of him.
Bucciarati stopped his own heart to evade Pesci's attack. And there's also the time when he was killed by Diavolo and kept going until the end thanks to Giorno and his own willpower.
Mista repeatedly shot Ghiaccio to stall him, despite being repeatedly hit by the ricocheting bullets. Also to push him towards a sharp tree branch. Cue impaled neck.
Fugo's GHA has him popping one of Purple Haze Distortion's capsules in his mouth, so that the opponent at close range can't see it coming and evade it. Even though PHD's virus can eat other viruses, and thus two viruses from two different capsules will cancel each other, now Fugo has a few seconds to cure himself before dying, as opposed to the 30-seconds limit that allowed Giorno and Illuso (the first time he's infected) to survive.
Ermes allowed herself to be surrounded by Sports Max's invisible zombies because she knew Max wanted to deliver the killing blow personally.
Dio's Castle stage:
The stage hazard is a chandelier falling down and damaging whoever's underneath it, referencing how Straizo defeated the zombies Page, Jones, Plant, and Bonham.
The Situation Finish has the defeated player getting thrown off the balcony, referencing Dio's ultimate defeat at the end of the story.
His HHA is his Scarlet Overdrive, the move he used against Dio Brando towards the end of Phantom Blood.
His GHA is the Sunlight Yellow Overdrive, the move he used against Bruford.
His theme song is called "Luck & Pluck", the name of the sword Bruford gave to him. Likewise, his sword attack is called "Sword of Luck and Pluck".
His special intro with Dio Brando has him reference their "youth", similar to one of their battle chapters, "Settling The Youth With Dio."
He has a special HHA called "My Final Hamon!" which revives him with increased strength but removes his Heart Heat Gauge.
If he's KOed in the last round with a light attack or chip damage, he'll fall down in the exact same sitting posture he was in when he died at the end of Part 1.
His Campaign 1 outfit is lifted from JoJo vol. 4. The pose he strikes in said cover is also the source of the gesture of one of his taunts.
His Campaign 2 outfit is lifted from JoJo vol. 2.
His Campaign 3 outfit is the all-blue suit lifted from JoJo vol. 5.

One of his special moves is the Sendo Wave Kick he used on Jack the Ripper.
His HHA is the punch move he used on a frog to demonstrate Hamon to Jonathan.
His GHA is a Hamon-charged Sunlight Yellow Overdrived Zoom Punch. During the same move, he recites a brief speech about mastering fear that he gave during his brief bout with Jack the Ripper, and during the animation, ripples exude around his feet similar to his first Hamon demonstration. He also starts the move with a pinky straight to the diaphragm, which he used on Jonathan and Speedwagon.
His Campaign 1 outfit comes from JoJo chapter 18, and includes the stripy pattern top hat he wore in his debut.
One of his normal outfit's alternate colour tints resembles his Phantom Blood PS2 game colouration.
His F + H command normal is his thumb-in-eye punch from his boxing match with Jonathan.
His counter-freeze move has two different animations, depending on what move it counters. If it counters a ground move, he grabs with both hands, much like at the near end of Part 1 when he tried to block Jonathan's final fire punch. If it counters an aerial move, he performs the same counter pose he did to William.
When he fires off his "Space Ripper Stingy Eyes" HHA, he bends backward in an animation very similar to both DIOs in the Capcom game.
There's also a special animation which plays when the KOed character is Jonathan, wherein he futilely tries to block the beam and whispers "Erina...", like he did in the final chapter of Phantom Blood.
His GHA ends with the same ice smash move he used to reduce Dire to a head, and even the mid-move speech is the same.
His theme song is called "Weakling, Weakling!", his Catch Phrase.
His Campaign 2 outfit comes from JoJo chapters 38-41.
His Campaign 3 outfit is the gold gentleman outfit from JoJo chapters 9-15.
In Campaign mode, one of the support characters is Jonathan's father George, who appears whenever you lose to a boss and makes it so all rankings post battle are S no matter what. The speech he gives (about not trying so hard to win but appearing to look like you're going to let your opponent have the win) when he appears is the same speech Jonathan remembered (during his fight with Bruford) hearing from George when a young Jonathan tried to pull his toy gun out of his dog Danny's mouth ("Instead of trying to pull it out so hard, try acting as if you'll give it to him and he'll loosen his grip.")
The Red Stone of Aja medal allows the Vampire and Pillar Men characters to play in any stage, whereas without it, they're restricted to indoor/night stages. This is a reference to the Pillar Men's goal of achieving immortality by using the Stone Mask.
His HHA is the Tommy Gun he used on Straizo, at the beginning of Battle Tendency.
His GHA is a Hamon Clacker barrage like he tried against Wamuu.
He has the fastest backward-running speed in the game: "Joestar Family's Secret Technique", and even shouts out "RUN AWAY!" while he does so, referencing how "running away" was his last resort move in the manga.
His theme tune is titled "New York's Jojo", after his debut chapter.
His "Happy happy joy-py" taunt is a reference to a panel where he greeted Santana, nearly the beginning of Part 2.
One of his taunt poses comes from one of BT's first chapters, where he beat up a bad-mannered customer in a restaurant who insulted him, his grandmother Erina, and his friend Smokey.
His Story Mode image pose is taken from another famous cover.
His Campaign 1 outfit comes from JoJo vol. 7.
His Campaign 2 outfit comes from JoJo chapter 57.
His Campaign 2 color scheme comes from JoJo vol. 11.

Caesar A. Zeppeli:
His HHA is the Bubble Launcher move he used against Joseph in their first battle.
His GHA is the same Hamon Bubble Lenses he used against Wamuu.
If he's defeated with a light attack, he leaves a bubble with his headband on it, a reference to his last moments after being mortally wounded by Wamuu near the end of Battle Tendency.
His theme song is called "Lonely Youth", a reference to his backstory.
His Campaign 1 outfit comes from JoJo chapter 62.

Her Campaign 3 gold outfit comes from JoJo chapters 71-72.
His Campaign 1 outfit is taken from JoJo chapters 64-70.
His Campaign 2 outfit comes from JoJo chapters 91-97.
His GHA is "Gathering Gale/Konketsusatsu", the same move he used against Joseph during their final fight.
One of his taunts is the infamous pose he took when awakening Esidisi and Kars, while he whispers his own name ("Wamuu...".) Sadly, he does not shout "AWAKEN, MY MASTERS!/MEZAMETAMAE, WAGA ARUJITACHI YO!"
His HHA is the same flaming kick he used on Loggins.
His GHA involves him stabbing his victim with his own veins and filling them with his burning blood, like he threatened to do to Joseph.
His crying taunt, "It's not fa-air!", is a reference to his battle against Joseph.
When fully beaten, his brain bursts out of his body.
His Mirror Match dialogue is lifted from his appearance in the non-canon light novel Jorge Joestar.
His GHA is also a reference to him achieving the Ultimate Lifeform status at the end of Battle Tendency, complete with the Stone Mask.
His Campaign 2 outfit comes from JoJo chapters 64-70 and 95-104.
His Campaign 3 outfit is the one he had when undercover in Switzerland, in chapters 83-95.
His Taunt C animation has him laughing, the same laughing fit he went into after a brief fight with Joseph in Switzerland.
Cairo Streets stage:
The Stage Hazard has Wilson Phillips' car crashing onto the ring. It's a reference to a sequence which happened between the DIO's Mansion fights and the final battle of Stardust Crusaders.
The Situation Finish is a reference to Noriaki Kakyoin's death at the hands of DIO.
DIO's Mansion stage:
The Situation Finish is a reference to how Vanilla Ice was defeated. Vampire and Pillar-Men characters (and Kars in his non-ultimate lifeform) will even be disintegrated by the sunlight.
His GHA references his then-newfound ability, at the end of Part 3, to stop time. The name of the GHA ("You pissed me off!") even references his lines to DIO after completing it in the manga.
His laughing taunt comes from the Part 3 JoJo team's encounter with Arabia Fats' The Sun stand.
One of his attacks is called "Here's your receipt", a reference to his "fight" against Steely Dan.
Another of his taunts (and also one of his moves) references his fight against Kakyoin, at the beginning of Stardust Crusaders, complete with drawing his finger along the brim of his hat.
"I'll be the one to judge you."
His special dialogue with Kakyoin is the same sumo discussion they had when menaced by a truck during the Z.Z/Wheel of Fortune chapter.
Jotaro: You like sumo wrestling, right Kakyoin? Specifically, the tactics around the boundary rope?
Kakyoin: Of course, I love sumo.
Kakyoin, if he wins: But Jotaro, punching your opponent is against the rules in sumo.
His theme song is called "Heritage For The Future", both a reference to the original name of Part 3, the title of the first chapter of SC, and the Capcom game.

One of his later free DLC costumes was inspired by his attire from various promotional material for the Capcom game.
One of his moves has him attacking you with a barrel of tar, much like he did against Empress.
The Hermit Overdrive he finishes his GHA with is also taken from his battle against Empress.
One of his winposes is the same Badass Armfold he did on Daniel J. D'Arby.
One of his winscreen images is him pointing at you and grinning, his farewell pose to Polnareff at the very end of Part 3.
Naturally, most of his taunts include his infamous Gratuitous English phrases, most notably his "OH! MY! GOD!" pose with his hands on his head, when he first laid eyes on how Egyptian toilets worked. Also included are "SON OF A BITCH!" and "HOLY SHIT!", used in quick succession during the Sun chapter when everyone burst out laughing.
His Campaign 3 outfit is lifted from JoJo chapter 146.
His Campaign 3 color scheme is lifted from the JoJo 6251 artbook.
His Campaign 5 alt is his hatless longcoat appearance from the end of Part 2. The blonde hair it has by default also gives it a striking resemblance to Joseph's OVA look.
His HHA is the regular Crossfire Hurricane, his first move in his battle against Polnareff. The ending of this move ("Tch! Tch! YES! I AM!") and its name ("Change my 3 wishes for 4") is a reference to his "revival" in the Cameo/Judgement arc.
His GHA is the large-scale Crossfire Hurricane Special he blindsided Polnareff with.
His theme tune is titled "HELL 2 U!", the same catchphrase-corruption he used against Judgement in his comeback.
His character artwork comes from his "revival" in the Cameo/Judgement arc.
His Campaign 3 outfit is lifted from JoJo chapters 116-117.
His Campaign 3 color scheme is lifted from JoJo vol. 14.
One of his taunts has him turn his back to the camera and invite his opponent for a nice big laugh, the same thing he did with Polnareff when they deliberately urinated down Cameo's pipe during the fight with his Judgment Stand.
His GHA is the 20 meter Hierophant barrier he tried using on DIO.
His HHA references how he beat the Death 13 Stand and is also similar to his "Punishment Time" super from the Capcom game.
One of his taunts is his laughter from the JoJo team encounter with Arabia Fats' The Sun.
Another one of his taunts is the famous "RERORERORERORERORERORERO" sound, complete with the cherry on his tongue.
His entrance animation is his sunglasses removal, which he meets with Joseph after the first encounter with DIO. It's also a nod towards New Kakyoin from the Capcom game.
His Campaign 2 outfit comes from JoJo vol. 16.
His Campaign 5 outfit is his scarf set from his very first appearance.
His GHA, where he uses Silver Chariot's afterimages after getting rid of the armor, is taken from his battle against Avdol.
His intro pose has Silver Chariot piercing several coins, taken from his introductory episode. If he's up against Avdol, the coins will be on fire, referencing Polnareff's debut chapters.
His theme song, "Aggression and Victory", comes from a line he spoke to Avdol in their first encounter.
One of his winposes has him bid the opponent goodbye whilst holding two fingers up, a pose very similar to the one he gave Iggy during their struggle against Vanilla Ice.
His character artwork pose is taken from the battle against Devo's Ebony Devil.
His Campaign 1 outfit comes from JoJo chapter 124 and even includes two noticeable strands of hair on the front of his hairdo. The alternate color scheme for the outfit comes from JoJo vol. 16.
Polnareff has unique greetings for most of part 5 whom he doesn't recognize given he hadn't met them yet since he is still healthy, however he DOES recognize Diavolo, a nod to the backstory that Polnareff's reason for being put in a wheelchair was infact Diavolo's doing.
A later free DLC costume for him was inspired by his attire from various promotional material for the Capcom game.
His GHA in his normal costume ends with him fiercely flying at the enemy and biting them on the nose. This is a reference how he defeated Pet Shop.
Iggy's GHA in his Special Costume ends with him latching onto the enemy's face and farting, referencing his debut "battle" against Polnareff.
His Campaign 2 costume is his initial appearance as a scraggly, older, realistic-looking dog (JoJo chapters 183-192).
One of his command moves summons a sand effigy of DIO, similar to a technique he pulls on Vanilla Ice.
His GHA, where he's assisted by J. Geil, references his fight with Avdol.
He has special intro dialogue against the female fighters, even receiving a special icon on the screen during battle.
His gun rotating taunt comes from his first fight against Polnareff.
His special intro against DIO and both their special winquotes reference the chapter where Hol Horse tried to assassinate DIO but failed.
His character artwork comes from his introductory episode.
His buff move is called "The gun is mightier than the sword", the same piece of wisdom he gave to Polnareff just before their fight.
His Campaign 2 color scheme comes from JoJo vol. 16.
His HHA is similar to how Cream devoured Avdol near the end of SC.
Part of his GHA has him in Cream form viciously circling around the opponent just like he did against Polnareff.
His "It's a Road Roller!" GHA's animation has him freezing time, then summoning a huge, yellow-painted steamroller over his enemy, and bashing said vehicle until it explodes, referencing the final fight of Stardust Crusaders against Jotaro.
If the DIO player faces a Jotaro opponent, this GHA has new properties: Star Platinum appears to fight back against the steamroller DIO drops (this is entirely cosmetic, as Jotaro still takes the full brunt of the damage).
Another reference to the final battle plays if the DIO player uses his Time Stop move, and then uses his HHA; said move will change to DIO throwing an array of knives at his victim. This is also a reference to DIO's knife throw super from the Capcom game.
His HHA is very similar to Shadow DIO's Checkmate! super from the Capcom game (though starting with a kick rather than a World punch.)
Another Capcom game reference can be found in his GHA, of all things. In the original manga, DIO's road roller didn't actually explode, and he simply believed Jotaro to be flattened to death. In the 90s Capcom game, however, it did explode after DIO was finished whacking it about. As it explodes in-game, it may be more of a reference to the Capcom game's depiction. It may also be a reference to the OVA, however, in that adaptation it was an oil tanker truck rather than a steamroller (thus it would make some sense for it to explode).
The pose The World takes when he stops time is eerily similar to his pose from the 90s OVA.
One of his taunts is him accusing "you" of watching him again with his hand on his face, similar to when Joseph tried to survey him in Part 3 during the Yellow Temperance chapter as well as a winpose in the Capcom game.
His special throw is the bloodsucking move he used in order to drain Joseph Joestar at the end of Stardust Crusaders. Furthermore, if done against a Joestar family member from Parts 1 to 6, he'll do a special animation wherein he stabs his own head and laughs about how great it feels.
His theme tune is titled "DIO's World", after the same chapter which shows him and his Stand fully-fledged.
His Mirror Match dialogue is the very same speech he gave to Enya about how conquering one's fear is how to live and that the ruler of the world knows no fear.
His Campaign 1 outfit is his "Angry" form, without his famous coat or headband, the same form he took after draining Joseph's blood in JoJo chapters 261-264.
His Campaign 2 outfit comes from the front cover of Over Heaven.
One of his Campaign 4 costumes is his Shadow DIO persona, complete with his shirtless torso and his face being completely shadowed out. This references DIO's early appearances in Part 3, where his face was hidden in shadow.
His other Campaign 4 costume has him sport the cloak he wore briefly during his pursuit of Joseph and Kakyoin. Its orange primary colour is based off of one of several manga illustrations, while its black colour is based off of the "DIO Second" Super Action Statue figure.
The game's ending credits theme is officially titled "The Long Journey Ends, Farewell My Friends" after the title of the final chapter of Part 3.
The Stage Hazard involves bolts of lightning striking the level. This begins with a bolt of lightning striking a large Pepsi sign. This is a reference to Chapter 420, where exactly this happens while Rohan is reading Hayato Kawajiri's memories.
The Situation Finish involves the defeated character in the Ghost Alley accidentally turning his back, and consequently being dragged to the dead world by ghost hands. This is a reference to how Yoshikage Kira was finally defeated.
Kira Estate stage:
The Stage Hazard has Yoshihiro Kira's phantom in a photo going with a knife slicing everything in his way. It's a reference to how he tried to kill the heroes in the Atom Heart Father chapters.
The Situation Finish has the loser slam into a load of books. One book in particular flips open, revealing Kira's own written message proclaiming his invincibility.
His HHA "You've finally entered... my effective range..." has him beating his opponent senseless. There's also a follow-up to this attack, "This Is My Homing Bullet", where a shard of glass is sent at his opponent, which then circles around them and hits them in the back like in his fight against Kosaku!Kira.
His GHA "I've Already Healed You" has Crazy Diamond fully healing his opponent before pummeling them, like he did with Yuuya Fungami.
His theme song is called "Golden Spirit", which references a line he said at the end of Part 4 about the people of Morioh.
One of his command moves has him fire a bullet from Crazy Diamond's hand, referencing the Ratt chapter where he and Jotaro hunted down and fought two Stand-wielding rats and shot at them from a distance by using their Stands to flick ball bearings and rifle bullets at high speed.
When his hair is taunted, it changes to a spiked-like shape, referencing how angry he became after his grandfather was killed by Angelo. Some of the counter-taunts even have references:
Jotaro: "We'll talk about your boring hair later." This is referencing their dialogue during his and Josuke's first meeting.
Koichi: "Josuke-san, isn't that hair old-fashioned?" This line is lifted from Rohan's thoughts on his hair.
Baoh: The narrator says that he doesn't like said pompadour's smell. This is a reference to how Baoh is able to distinguish friend from foe by their own scent.
His Campaign 1 outfit comes from JoJo vol. 42.
His Campaign 1 color scheme is the gold suit from JoJo vol. 33/39/41.
His Campaign 2 outfit comes from the JoJo 6251 artbook.
His Campaign 2 color scheme comes from JoJo volumes 30/34/47.

One of his taunts is a reference to the chapter where he met (and fought) his future Love Interest Yukako Yamagishi, even doing the same arm fold pose as well.
"You made me go through such a thing! It's too late. That's why I'm telling you I hate you."
One of his winposes is a happy arm flex and a shout of "Yatta!/I did it!", like he did after using Echoes to get one over on Tamami Kobayashi.
The moves "Boosh", "Woosh", and "Boyoyoing" are the same bits of onomatopoeia his Echoes uses and reference his brief struggle against Yukako Yamagishi.
His Campaign 1 outfit comes from JoJo chapter 390, a.k.a. the "Highway Star" arc.
His Campaign 2 outfit is the pyjama set he was wearing when Yukako kidnapped him, in chapter 297.
His Campaign 2 color scheme is the gold suit from JoJo vol. 33/39/41.
If he performs his GHA on his enemy, he glares at them, and then a flowerpot flies out of nowhere and smacks him in the face, just like what happened in his first fight with Josuke.
One of his taunts is the muscle stretch he does in Trussardi's introductory episode after Pearl Jam fixes his stiff shoulders and gets rid of his dead skin.
His Campaign 1 color scheme is the gold suit from JoJo vol. 33/39/41.
Another of his outfits undresses him down to his vest, much like he did during the Pearl Jam chapter when he celebrated Trussardi's food skills.
His HHA "I'm Gonna Blow Off Your Arm Just By Using My Pinky" involves RHCP taking Akira's foe and using the floor to hit them. This is what he did (albeit with energy cable lines instead of using the floor) in the beginning of Diamond is Unbreakable in order to kill Keicho Nijimura. The move's name itself is the same threat he gave to Josuke and Koichi.
If he's KOed in the last round with a light attack or chip damage, he'll remain standing but very hunched over, referencing how after being beaten by Josuke in the manga, he passed out while standing up.
One of his taunts involves Red Hot Chili Peppers holding its pinkie out with Akira claiming he can blast his victim's arm off with said pinkie alone, the same threat he gave to Josuke and Koichi.
His Campaign 1 color scheme comes from the JoJo A-GO-GO! artbook.
His Campaign 5 outfit is the Speedwagon Foundation disguise he used during his attempted assassination of the by-then very elderly Joseph Joestar.
His HHA "I'll take your reality for myself" references an action he did against Koichi in his introductory episode, where he took off some of Koichi's memory pages, ridding him of any plot-vital memory as well as taking some weight off of him.
His GHA "Heaven's Door" is a reference to the Cheap Trick chapter where he wrote "I cannot attack Rohan Kishibe" in Masazo Kinoto. He also did this against Koichi, but the animation of the GHA itself is a reference to the former.
His theme song is called "Pink Dark Boy", his then-latest manga in-universe.
One of his taunts is "Do you think I, Rohan Kishibe, write manga for money?", a rhetorical question he gave to Hazamada and Koichi in his introductory chapter.
If he's KO'd by Kosaku's "Bites The Dust" GHA, he screams "Koichi-ku~n!", referencing his "death" after looking at Hayato Kawajiri in the end of DIU.
His projectile attack is the pin rain he did against Josuke.
His Campaign 1 outfit comes from Episode 16: At A Confessional.
His Campaign 3 outfit comes from JoJo chapters 381-383.
His Campaign 3 color scheme comes from the JoJo A-GO-GO! Artbook.
One of his poses is directly lifted from the cover of Rohan At The Louvre.
His infamous phrase "But I refuse./Daga kotowaru." is one of his taunts as the "no" option in most of the game's selection boxes.
One of his taunts is the line he said to Shigechi before killing him. His pointing pose is the same one he did to Koichi as well.
"I'm going to have to eliminate you."
His theme song is called "Yoshikage Kira Just Wants A Quiet Life", referencing the chapters where he was introduced.
One of his projectile attacks involves tossing a coin which has been primed (turned into a bomb) by Killer Queen. During his first encounter with Shigechi, he tricked him into picking up such a coin with the Harvest Stand.

His Campaign 1 color scheme comes from JoJo volume 38.
His Campaign 2 outfit comes from JoJo vol. 44 and chapters 412-417.
Just before he unleashes his HHA, the pose Kira takes is the very same one he unleashed on Koichi.
If he's KO'd by Kira's HHA or GHA, he cries out "Jo~suke~!", referencing his death.
He has fast forward and backward runs, called "Bucket Brigade", where he's assisted by Harvest, referencing how he managed to escape from Josuke and Okuyasu in his introductory episode.
Some of his poses have him holding two coin-filled painting cans, referencing how he tried to buy Josuke and Okuyasu's friendship.
His "Bites The Dust" ability involves throwing young Hayato Kawajiri at the enemy, Killer Queen's Bomb No. 3 being activated, and the entire stage exploding, after which the timer rewinds 10 seconds and voids any transformation done by any character. This is a reference to his encounters with the heroes the day after receiving Bites The Dust from his father Yoshihiro.
One of his taunts is his Catch Phrase. In it, he does his pose from one of the covers of Part 4 which had him going head-to-head with Josuke:
"I, Kira Yoshikage, have luck on my side."
One of his round winning poses has him answering a callphone call from his (Kosaku's) workplace boss and frantically apologizing for being late while also bowing, much like he did mid-battle against Josuke.
Should he fight against Kira, he wonders if meeting his past self was an effect of Bites the Dust.
One of his taunts is the calculation pose he did in the final fight against Josuke.
His Campaign 5 casual outfit is his self with spiky hair he had when Kira and Kosaku first swapped faces.
One of his quotes when he wins a round has him call his opponent "Minako-san", the name of a woman he killed with Killer Queen.
Naples Station stage:
The Situation Finish has the loser being hooked in the head by Pesci's Beach Boy Stand whilst Prosciutto is heard telling him to get moving. The train that they're on leaves, dragging the poor loser with it.
Rome Streets stage:
The Stage Hazard has Secco using Oasis to create dangerous mold-filled areas.
The Situation Finish has the loser being thrown into a truck, referencing Ciocolatta's defeat.
Guido, Narancia, and Fugo have taunts where they begin dancing like they did when they had Mario Zucchero captive.
Koichi and Giorno's special intro and victory phrases are about Koichi's things being stolen at the start of Part 5:
Koichi: Where's my passport and luggage?
Giorno: Sorry, I sold it already.
Fugo's intro dialogue against Narancia regards Narancia's mathematics lessons and how upset Fugo gets over an incredibly wrong answer. If Narancia wins, he immediately begs forgiveness from Fugo.
His HHA involves a close up of someone's face as Gold Experience punches them. The resulting scene varies depending on the character:
Jonathan: He digs his Stand's thumb into Jonathan's eye, just like his father Dio did in Part 1.
Dio Brando: Half of Dio's face will seemingly close and become dead, similar to how Dio was when he regenerated himself after being cut in half by Jonathan.
Joseph: His face contorts into a similar reaction to his "Oh No!" face.
Lisa Lisa: She'll put her hand in front of her mouth, quite like how she did when she mourned Caesar's death.
Old Joseph: His face contorts into his "Oh! My! God!" reaction face.
Polnareff: Jean-Pierre's tongue pops out, comically stretching and distending to around his right ear just like in the Hol Horse-Boingo chapter in Part 3, when he tried to warn Jotaro and the others that Hol Horse had him at gunpoint from behind.
Vanilla Ice: His face contorts similarly to how he got angry at being seriously wounded by Polnareff.
DIO: Gets the same skull-crushing punch to the side of his head that Jotaro used on him to weaken him during their battle.
Rohan: His face contorts into the same one he made when thrashed by Josuke for first time.
Shigechi: Ends up with his face disfigured in the same fashion as when Kira kills him.
Kira: His face warps similar to when he first got hit by Star Platinum.

Narancia: Makes the same expression he made when Fugo stabbed him in the cheek with a fork.
Diavolo: His face contorts similar to after getting punched by Gold Experience Requiem.
Pucci: The camera tilts. Gold Experience will also put its free hand on the other side of Pucci's head to keep him from using his gravitational abilities. This is a reference to his death at the hands of Emporio and Heavy Weather.
Funny Valentine: A face contortion similar to when Johnny's unique GHA is used on him.
Full health!Baoh: His expression remains unchanged, referencing how hard is Baoh's skin when Ikuro isn't in full control.
His GHA evolves his stand into Gold Experience Requiem, like it did at the climatic battle between him and Diavolo. The name of the move ("Never-ending End") is also a reference to Diavolo's final fate at the end of Vento Aureo.

His GHA evolves Purple Haze into Purple Haze Distortion, referencing the Vento Aureo sequel spinoff. Fugo starts it off by biting into one of Purple Haze's poison capsules, infecting the victim with it. Purple Haze then pummels the diseased and helpless victim, further injecting the virus into their body and killing them in the same way Illuso was killed.

One of his taunts references a line he said before killing Bruno for the first time. His GHA is also a reference to this act.
His entrance animation briefly shows Doppio, who seemingly takes his shirt off and transforms into Diavolo, a reference to both Doppio being Diavolo's split personality and his first proper appearance and brief battle against Polnareff in Vento Aureo.
His theme song is called "His Name Is Diavolo", referencing the chapters where his identity was exposed.
The first bars of "His Name Is Diavolo" contain a faint sound of a cell phone ringing, referencing how Doppio communicates with the Diavolo personality.
One of his taunts references his first battle against Bucciarati.
"Results! This world only remembers the results!"
His Campaign 4 unlockable costume has him painted entirely black, wearing a trenchcoat, shirt, and tie combo with short hair to boot, just as he looked in his first few appearances.
As of Campaign 5, he got another alternate costume: a soccer outfit. Specifically, his soccer kid disguise he wore when he killed Abbacchio.
When KOed with a light attack or chip damage, he falls onto his knees, his right arm raised a bit with its hand limp as he looks fearfully back at his enemy. It's the exact same posture he was in at the end of Part 5 where, after countless "deaths", he went mad and screamed "GET AWAY FROM ME!!" To a little girl, no less.
Her Campaign 1 outfit A is extracted from Stone Ocean vol. 1 (JoJo vol. 64), her outfit B from Stone Ocean vol. 4 (JoJo vol. 68), and her outfit C from Stone Ocean vol. 12 (JoJo vol. 76).

Her Campaign 1 outfit comes from JoJo chapter 615.
His HHA has Whitesnake removing his opponent's ability CD, except that it doesn't leave a "slot" behind (like something has been cut out) like it did in the manga.
If Pucci pulls off his C-MOON GHA on the Kennedy Space Center stage, a special animation briefly plays of him jumping upward to a nearby shuttle.
C-Moon's punches can turn parts of the enemy's body inside out; however, using such attacks on an enemy already affected will interrupt the effect. This has been exploited in the manga, during the battle at the Space Center.
One of Pucci's moves is a throw-type attack where he briefly forces a sort of hallucination on his victim. When this happens, a special animation plays for each character. (These animations also play after the victim is hit with Giorno's HHA.)
Jonathan: Wipes his face with his handkerchief just like at the start of Part 1 when he defended Erina from the two bullies.
William: A sneezing fit, referencing his first meeting with Jonathan where he went into one upon peppering his sandwich a bit too much.
Part 1 Dio: Attempts to slide his head back together, much like he did after briefly being bisected by Jonathan.
Caesar: Swings an ineffective punch, similar to how he acted against Wamuu in his death throes.
Polnareff: The same pose seen when he briefly laments Avdol and Iggy's deaths.
Part 3 DIO: Rapidly claws his head, spewing blood, just like he did when he drained Joseph of his blood.
Okuyasu: When he discovered how good Tonio's food was.
Giorno: Unclear, but possibly a reference to when he first discovered his healing application of his stand, namely putting his new eye in.
Diavolo: His "GET AWAY FROM ME!!!" pose toward a little girl at the end of Part 5.
Gyro: Thrashes about re-enacting the bad joke he told Johnny in the chapter "7 Days A Week."
His Campaign 5 outfit is the one he wore in one of his flashbacks.
Johnny's and Gyro's mirror matches have them wondering if the match is an effect of President Valentine's Stand.
Each time he uses his HHA, Tusk evolves from Act 1 to Act 4: Act 1 makes Act 2 appear and shoot to the ground, hitting the opponent. Act 2 shoots himself with Act 3 and appears behind his opponent before shooting them repeatedly. Act 3 and Act 4 makes Act 4 appear and start a barrage of punches, hitting the target into the ground.
His GHA has him thrown off his horse, activating Act 4, after which he shoots his opponent before Tusk flies in and starts punching them repeatedly, similar to his fight against Funny Valentine.
Furthermore, if done against Valentine after the latter collected all the corpse parts, it breaks through the Love Train barrier protecting Valentine, and then thrashes Valentine's D 4 C, dealing damage to Valentine as well.

When Ball Breaker makes contact with Valentine in his GHA, Ball Breaker instead passes by Valentine, who nonetheless gets thrashed by the residual Super Spin energies left behind in Gyro's wake.

His HHA is directly taken from his battle with Diego Brando and Hot Pants, except this time it connects.
His GHA has him pulling the opponent to a parallel world and throwing them at the opponent's alternate version, creating a paradox and obliterating both of them in Menger Sponges like he did against Wekapipo.
His Campaign 3 outfit is the red Orcus In His Throne costume from the Steel Ball Run chapter 95 front cover.
His Campaign 3 color scheme is the yellow outfit from Steel Ball Run chapter 59.
His Mirror Match dialogue has the second Valentine threaten to make his opponent "docile, like the winter catfish." This line was a threat given to Lucy Steel by one of the men that Valentine sent to take care of her.
Wall Eyes stage:
The Situation Finish has the opponent fly near Yasuho, scaring her and making Joushuu angry enough to cave their head in with a rock. The bit with Joushuu and a rock is similar to what he tried to do to Josuke when he first saw him with Yasuho.
The extra chapter in the Jojolion story mode, where JoJolion!Josuke fights Baoh, is named "Baoh Raihousha" or "Baoh the Visitor", the original title of the manga.

His alt costume from Campaign 5 is his "ORA ORA/WRYYYY" shirt from the front cover of Jojolion volume 1.
His HHA has him using the laser cannon he killed Walken with.
Since he doesn't talk properly in his Baoh form, instead you get the game's narrator calling his attacks instead.
His intro pose has him in his newer clothes after Grandma and Grandpa gave him and Sumire/Violet asylum, with the "palm to the face" stance seen at the very beginning of Baoh, transforming into Baoh using the same sequence he used in the ruined building some pages before.
His character artwork and one of his win screen poses is lifted from the cover of Baoh Volume 2.
One of his projectile attacks, where he detaches one of his arm blades, references how he first defeated Walken.
His default costume's D colour tint is taken from the Manga Realization Figure.
His default win quote is the announcer shouting, "Kore ga... Kore ga... KORE GA BAOH DA!" (This is... this is... THIS IS BAOH!) This is one of the more famous lines from the manga, spoken by the narrator as Baoh is seen fully for the first time in Chapter 3.
