Joseph Joestar (Stand: Hermit Purple)Josuke's father, who conceived him in an affair with Tomoko when she was in college. See Joseph Joestar.
Voiced by: Megumi Toyoguchi (eps 1-15), Shizuka Ito (eps 31-39) (TV anime, JP), Allegra Clark (TV anime, EN)
Played by: Arisa Mizuki (live-action movie)
Josuke's mother, who is deeply in love with Joseph. She's rather normal, being as good of a parent as she can to Josuke.
- Awesome by Analysis: Unknowingly thwarts Angelo's attempt on her life when she noticed that the milk bottle he gave her had already been opened.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; hers has her complaining that Josuke ate her favorite snack again, and threatening to drink his favorite juice in retaliation.
- Daddy's Girl: Implied. She takes a long time to change Ryohei Higashikata's bedroom, depressed over his death.
- Distracted by the Sexy: Like most females when in Jotaro's company. Even when he's clarified that he's not Joseph, she's still spaced out in his presence.
- Distressed Damsel: Gets held hostage several times throughout Part 4.
- Dude Magnet: Literally every male she comes across is smitten by her.
- Failed a Spot Check: When she first saw Jotaro, she thought he was Joseph. Even with how Mr. Fanservice runs in the Joestar family and ignoring how Jotaro is half-Japanese, it should be remembered she had her affair with Joseph when he was already grey-haired and with a beard, compared to the clean-shavened clearly young adult Jotaro.
- Forehead of Doom: Has a rather large one in her first manga appearance, particularly when she's pissed off. Later depictions of her toned down her forehead greatly.
- Good Parents: She's a good mother to Josuke despite being a single parent, and tries to make sure that Josuke acts responsibly.
- Hair-Trigger Temper: She slams a guy's head into his car when he tries to flirt with her.
- Locked Out of the Loop: In two ways; first, she is left completely in the dark about the nature of Stands and the battles that Josuke fights over the course of Part 4; second, Josuke deliberately makes sure not to tell her that Joseph is back in town during said time.
- Likes Older Men: Still in love with Joseph, whom had an affair with her, despite him being old enough to be her father.
- MayDecember Romance: She was the mistress of Joseph, who was older than her father. Despite this, she's still madly in love with Joseph.
- Mum Looks Like a Sister: Given how informal the relationship between the two seems to be, you'd be forgiven for believing that Tomoko is Josuke's older sister rather than his mother.
- Stacy's Mom: Okuyasu certainly thinks so, much to Josuke's chagrin.
Voiced by: Katsuhisa Houki (TV anime, JP), Michael Sorich (TV anime, EN)
Played by: Jun Kunimura (live-action movie)
Josuke's grandfather. A police officer who served in Morioh for 35 years. A jokester who is somewhat neglectful of his duties, but genuinely eager to help his community. Gets killed by Anjuro.
- Adaptation Expansion: The live action movie does this to him. In the manga, he becomes a Forgotten Fallen Friend after the Angelo Arc, and every enemy Josuke encounters is simply due to circumstance. However, in the movie, his death is what motivates Josuke to protect Morioh like he once did. He's also given an Adaptation Origin Connection to Kira, having been motivated by his inability to solve Reimi's murder.
- Big Fun: He's depicted as both portly and very jovial.
- Cool Old Guy: He's a friendly, humorous, and all around likable guy.
- Contrived Coincidence: While targeting Josuke, Anjuro recognizes him as the officer who originally arrested him.
- Forgotten Fallen Friend: His final appearance in the manga comes three chapters after his death. The anime barely expands his character, showing a family photo of him alongside Tomoko and Josuke on the final episode; he's not even added to the Great Days opening alongside the other defeated allies and Keicho.
- Friendly Target: He's the grandfather of the main hero, and one of the first few characters to get killed in the part.
- Let's Get Dangerous!: Gets a fearsome look in his eyes when he finds out a serial killer's on the loose. Sadly, since the killer recently gained supernatural powers...
- Open-Minded Parent: His unmarried daughter had a love affair with a man more than twice her age which produced an illegitimate child, and Ryohei loves them both with all his heart. Considering Japanese attitudes regarding illegitimate children, that's indeed saying something!
- OOC Is Serious Business: Always jolly and friendly, he becomes uncharacteristically serious when he hears about Angelo's murders on the news.
- Overprotective Dad: Looks the other way when Tomoko slams an overly flirtatious man's face into his car.
- Sacrificial Lion: He is the first good character killed by a villain.
- Small Role, Big Impact: Despite getting killed off at the start of the series and a subsequent Forgotten Fallen Friend, his death was what motivates Josuke to carry on his legacy to protect Morioh.
Nijimura Family Patriarch (Stand: unnamed)
Voiced by: Naomi Kusumi (TV anime, JP) Kellen Goff (TV anime, English)
The father of the Nijimura brothers. The loss of their mother and the family's descent into poverty made him abusive, but his financial problems were solved by joining DIO's henchmen. However, the flesh bud implant that came with this ran wild upon DIO's death, causing him to mutate into a monstrous form that would impair his intelligence and ability to speak, all while healing any wounds instantly. Keicho subsequently searches for a means to end his father's miserable life.
- Abusive Parent: He would often beat his sons without a second thought when he was stressed.
- And I Must Scream: Being turned into an unkillable blob that can't think or speak properly, the fate of anyone who had a seed of DIO inside them after DIO was killed. Even worse, despite not being able to speak or otherwise communicate, he retains enough of his mind to remember who he was and what he's lost enough that he's spent ten years constantly trying to reassemble a torn-up photograph of his family prior to his wife dying and his transformation, and crying for days on end between attempts.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; in addition to the manga explaining that he adopted Stray Cat, he's also shown having lunch at Tonio's. Okuyasu hopes that Pearl Jam will heal him, but all it does is make his monstrous body more shiny and vibrant, which Okuyasu is fine with.
- Body Horror: Mutated into a massive creature with rough, blistered green skin, no ears, and something resembling a beak for his nose and mouth.
- Green Is Gross: When he's first introduced, he looks like a giant blob of gelatinous mass that oozes slime; fittingly, his skin is also green.
- Healing Factor: His unnamed Stand seems to give him this power, allowing him to regrow a severed arm. His sons are initially motivated to use the Stand Arrow in order to create a Stand user capable of killing their father, in order to put him out of his misery.
- Humanoid Abomination: Mutated into an almost mindless green blob monster with a beakish mouth.
- Karmic Transformation: He became the savage beast he was to his sons.
- No Name Given: We never learn his given name nor the name of his Stand in the manga, anime, or supplementary materials. The live-action movie does, however, give him the name Mansaku, following the Numerical Theme Naming of his sons in that "man" is the Japanese number 10000.
- Progressively Prettier: Starts off being utterly disgusting before Art Evolution made him into a cartoony Mon-like creature.
- Sanity Slippage: The seed not only decreased his looks, but his rationality as well, being completely animalistic by the time of the story.
- Troubled Abuser: He pretty much suffered from losing his wife and business as much as his sons suffered from him back then.
Tamami Kobayashi (Stand: The Lock)
Voiced by: Satoshi Tsuruoka (TV anime, JP), Frank Todaro (TV anime, EN), Kazunari Tanaka (All-Star Battle)
A local thug who shakes down people for money by using his Stand, The Lock, which places a heavy padlock on a target's heart that amplifies feelings of guilt. After his defeat at the hands of Koichi and his newly awakened Stand, he ceases his criminal activities and helps the party from time to time.
- Advertised Extra: Prior to Rohan's appearance, he often shows up in chapter covers even though he's unimportant compared to the heroes. This even extends to the anime, where he's present in all three intros, but he's completely absent in all episodes featuring the "Chase" opening.
- Anime Hair: His pompadour is even bigger than Josuke's.
- Art Evolution: When he's first introduced, he's a regular sized man with a regular amount of hair. Over the course of a few chapters, his design drastically changes to one in which he's about the same size as the diminutive Koichi and his hair is drawn more pronounced. In the anime, he's short to begin with.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; He's seen arguing with Hazamada, who claims that Tamami purposefully spilled juice on his copy of Pink Dark Boy.
- Defeat Means Friendship: After being defeated, he becomes a follower of Koichi.
- Emotion Bomb: The Lock is created from the victim's sense of guilt, amplifying it to the point that they're willing to do anything to alleviate it.
- Freudian Excuse: When Koichi breaks his mother from his control, he's baffled because his own parents don't trust him, hinting that he has a bad relationship with them.
- HeelFace Turn: Brought on by not wanting to have his eardrums explode by Echoes. However, during the Surface arc, he comments on his admiration for Koichi when he's alone, showing that his reform could be genuine.
- Jerkass: He's a Con Man whose whole M.O is getting people to either believe they've accidentally done terrible things to him, such as running over a cat (actually a realistic toy), or pulling Wounded Gazelle Gambits by acting so pathetic that people feel guilty standing up to him. This activates The Lock, allowing him to extort his targets for more and more cash lest they fall victim to his Stand's Psychic-Assisted Suicide.
- Jerk with a Heart of Gold: Becomes this after being humbled by Koichi.
- The Knights Who Say "Squee!": A Stand user himself, and is a fan of Rohan Kishibe's works. In Thus Spoke Rohan Kishibe: Mutsukabezaka, he receives an autograph made of coffee in a paper sheet.
- Loan Shark: After his defeat, he starts working taking back loans for casinos and the mafia, apparently by making people feel guilty if they don't pay.
- Mundane Utility: By holding The Lock in his hand, he can tell if someone is lying or cheating, without actually using it on his target. Rohan summons him during the dice game between Rohan and Josuke to make sure Josuke doesn't stop cheating before he can figure out Josuke's trick.
- Psychic-Assisted Suicide: If The Lock becomes heavy enough, its victim will become so guilt-addled that they'll think suicide the only proper thing to do.
- Teeth Flying: Okuyasu punches him in the face hard enough to make his front tooth fly out. It gets healed back up by Josuke.
- Took a Level in Kindness: At first he was greedy, petty, and abused his power to some disturbing degrees. After his bout with Koichi, Tamami mellowed out quite a bit; helping the heroes, getting information on Hazamada, and while his power use isn't exactly ethical, he seems a lot less willing to hurt people for his own benefit. Even when he returns as part of a scheme to put pressure on Josuke, Tamami's not doing it out of any malice and seems happy to see him again.
- Wearing a Flag on Your Head: He wears two. The front of his shirt has the Union Jack while the back had the American flag.
- Wounded Gazelle Gambit: One of his favourite tricks to spark guilt in his victims is to injure himself and shifting blame to another (such as taking a pratfall after being pushed to purposefully knock out his tooth).
- Younger Than They Look: Tamami looks like he's on his forties thanks to his wrinkled face, but is actually just barely older than Rohan, and states to have graduated high school just a few years before the start of the story. This is subverted in the one-shot, where he looks closer to his age.
Toshikazu Hazamada (Stand: Surface)
Voiced by: Hiroki Shimowada (TV anime, JP), Lucien Dodge (TV anime, EN), Taiki Matsuno (All-Star Battle)
A bully at Josuke and Koichi's high school. He uses his Stand, Surface, to alter a life-size wooden mannequin into an exact double of someone. If the Surface-doppelganger makes eye contact with whoever it's imitating, the real person will be locked into copying the mannequin's movements.
His Stand, Surface, is named after the band of the same name.
- Art Evolution:
- In the same vein as Tamami Kobayashi, he was originally introduced as a regular-sized man. However, after being discharged from the hospital following his initial encounter, he became much smaller, being practically just a head taller than the diminutive Koichi.
- In the anime, he is introduced already slimmed down and short. However, he's drawn with sharper and darker Bishounen features during his introductory arc and later gets a more simplified, child-like design after his defeat. This shows that he's no longer a threat to the main cast.
- Ax-Crazy: Well, when you use your Stand to stab people in the eye over an argument about Manga, you just might have issues.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; he's arguing with Tamami, claiming that he purposely spilled juice on his copy of Pink Dark Boy.
- Big Brother Bully: Rohan mentions that Hazamada likes to torment his younger brother when reading him with Heaven's Door.
- Copied the Morals, Too: Downplayed. Surface is still part of Hazamada and obeys, but the longer it holds someone else's form, the more it begins to act like that person, likes and dislikes included. Hazamada notes with disdain that when he had Surface become the woman of his affections, Surface became as repulsed by him as she was.
- Defeat Means Friendship: After his defeat, he wants to befriend Koichi Hirose as both are fans of mangaka Rohan Kishibe. The most downplayed example of this in all of Part 4, really, since nobody really likes him and his role in the story afterwards is a minor part in Rohan's introduction.
- Depower: Unlike most Stands, the existence of Surface is tied to a physical object, a wooden dummy that Josuke ultimately destroys. This leaves Hazamada with no powers except the ability to see other Stand users.
- Disproportionate Retribution: Tamami narrates to Koichi and Josuke how Hazamada used his Stand to force someone to rip his eye out just because the guy had argued with him. He also tried to stab someone in the mouth with a box cutter for insulting him, but by then Josuke had already found him.
- Dub Name Change: His Stand's name is changed to "Show Off" in the Crunchyroll subtitles and English dub.
- Even Evil Has Standards: He is creeped out by Rohan's eccentricities to the point of puking upon seeing him lick a spider's innards.
- Eye Scream: He attempts to do this to Josuke with his Stand ability. It doesn't work, but it would have if the wound had been just a few millimeters deeper (previously, Hazemada inflict this to his ex-friends as described above).
- Green-Eyed Monster: He holds a hatred of popular people; even jealously attacking his own Stand once it adopts Josuke's appearance and is greeted by many school girls.
- Hate Sink: Rohan notes that readers would hate him if he were a character in his manga.
- Hazy Feel Turn: Unlike other Defeat Means Friendship characters like Tamami, Yuya, or even Yukako, there's more of a moral "bleakness" about Hazamada. It's notable that his crime before becoming an ally was to make somebody rip an eye out after having a disagreement with him, an act that few of the other allied Stand users had sunk to, and it's noted repeatedly that he was moments away from pulling off an Attempted Rape on a classmate with his Stand. Rohan even gives a reminder that he's not a particularly good person when he uses Heaven's Door on him. However, after his defeat he acts friendlier to the heroes, and his more off-putting characteristics are played with a bit of humor.
- Laser-Guided Karma: The two guys he attacked show up to beat him up, albeit because Josuke healed them and told him where he'd be.
- Loveable Rogue: How his off-putting tendencies and inner moral deficiencies get played after "joining" Team Josuke.
- Odd Friendship: He gets along with Koichi due to their similar taste in manga. Keep in mind that Koichi is a Nice Guy while Hazamada is not.
- Older Than They Look: After being beaten up by two bikers and befriending Koichi, Hazamada suddenly looks quite a bit younger than before, partly because he suddenly looks a lot shorter. On the other hand, Koichi is the primary point of view, so this may be an indication of Hazamada no longer being a threat to him.
- Otaku: A big fan of Rohan Kishibe's Pink Dark Boy and nerdy interests in general.
- Out of Focus: After being beaten by Josuke, he appears again during Rohan's introductory arc, and once more during the Morioh meet-up after Shigechi's death. But after that, he doesn't appear again until the day to say goodbye to Reimi.
- No Respect Guy: His own Stand makes fun of him.
- People Puppets: Surface uses an interesting version of this. Once it begins mimicking a person, it can actually control their actions so long as it maintains eye contact. Specifically, whenever it makes a motion while doing so, the one mimicked will wind up doing the same motion, albeit with the other side of their body, as though they were Surface's mirror reflection.
- Screw This, I'm Outta Here!: When Jotaro rounds up other Stand users to enlist in the investigation of Shigechi's killer, he opts out citing he wants nothing to do with such a monster. Justified as Hazamada has lost his powerful Stand powers and would be killed quickly by Kira.
- Shout-Out: Surface is a reference to Perman's (a work of Fujiko Fujio) eponymous copy-robots. In the series, the copy-robot transforms into an identical clone to help the main character keep his secret identity during missions. Surface mentions Perman by name in the anime adaptation, then gets upset when Josuke expresses his confusion about the subject.
- Small Name, Big Ego: Seems to be under the impression in his introductory arc that he's part of a menacing network of Stand users created by Keicho, but really the man never gave a damn about any user who couldn't kill his father, and he really doesn't have any information on others like him. Red Hot Chilli Pepper mocks him for thinking so after Hazamada's defeat.
- The Sociopath: Rohan's use of Heaven's Door on him reveals he tortures animals and his younger brother and nearly raped a girl he had a crush on...and as such, is absolutely terrible writing material for Rohan. Naturally, he's really crushed by it.
- Story-Breaker Power: Nonfatal example, but a Stand like Surface could very easily be used to kill any Stand user from a distance at little risk to the user, which very nearly kills Jotaro without him even noticing. With a guy as scummy as Hazamada, it's a good thing that it was destroyed and seemingly never repaired, but no question it could've come in handy against nearly any opponent in the part.
- Synchronization: Played With. Unlike most Stands, the maiming and destruction of Surface doesn't seem to affect Hazamada at all. However Hazamada had earlier stated that the wooden puppet was simply just something his Stand inhabited and its destruction probably had no effect on the Stand itself.
- This Loser Is You: He's an otaku, and he's a creepy loner who fantasizes about killing or raping his classmates. Rohan even gives him a "Reason You Suck" Speech, and considering he's more or less an Author Avatar, you can't help but think that's intentional.
- Weirdness Magnet: Hazamada was the one who posits the idea that Stand users invariably attract other Stand users, and he repeats this statement at the meeting concerning Shigechi's death. It may have been why when Koichi finds Rohan suspicious, Hazamada brings up the possibility of him being a Stand user.
Yukako Yamagishi (Stand: Love Deluxe)
Voiced by: Mamiko Noto (TV Anime JP), Chinatsu Akasaki (Eyes of Heaven), Faye Mata (TV Anime EN)
Played by: Nana Komatsu (live-action movie)
A beautiful classmate of Koichi's who falls deeply in love with him due to his pure heart and potential. Her Stand, Love Deluxe (named after the eponymous Sade album), makes her hair prehensile.
- Advertised Extra:
- Araki likes to put her in chapter covers, despite her overall unimportance to the story.
- She also makes very significant appearances (she even makes more appearances than Rohan himself, who is quite important in the story) in the third opening, "Great Days", despite having no real role in the final third of Diamond is Unbreakable.
- Alliterative Name: Yukako Yamagishi.
- Ascended Extra: Gets a far bigger role in the live-action movie, and is present from the beginning, allying herself with the Joestars from the start, whereas she only joined the heroes' side after being defeated in the anime/manga.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; She and Koichi meet up at the Angelo Stone to go on a lunch date together.
- Bare Your Midriff: Not all the time, but given her height, the top of her Sailor uniform frequently leaves her belly exposed, most notable in the 3rd opening.
- The Bus Came Back: While several of the other "Duwang Gang" characters (Josuke, Okuyasu, Koichi, Tonio, Akira, and Tamami) had cameos in Thus Spoke Kishibe Rohan, Yukako hadn't shown up again...until "Episode 9: D.N.A.," where she's central to the plot (Rohan's 'client' is friends with Yukako's mother).
- Character Tics: Her left eye has a tendency to twitch whenever she gets mad or worked up over something.
- Clingy Jealous Girl: She jealously attacks a girl that she believes to be a potential rival, almost burning her to death. And then there's her reaction to Koichi's escape attempt once he gets Echoes Act 2:Yukako: You belong to me! You belong to me, but you dare defy me? Even though you belong to me?!
- Control Freak: The reason her first attempt at a relationship with Koichi failed. She took control of his life by kidnapping him, forcing him to study using horrifyingly abusive methods, and generally considering him less of a romantic partner and more a baby chick that needs protecting from everyone and himself. She eases off on this after Koichi saves her from being Impaled with Extreme Prejudice despite all the things she did to him.
- Custom Uniform: Her Sailor Fuku is noticeably different from the ones other female students wear at Budagaoka High School, being blue instead of green and having a rose embroidered on one sleeve.
- Cute and Psycho: Initially, she appeared demure, shy, and sweet around Koichi before quickly showing her temper and obsession. She also tends to live in her own world, which makes her dangerous when someone doesn't realize it or refuses to follow her script.
- Defeat Means Friendship: Being bested by Koichi, then rescued from a certain death by Echoes, who pasted a "Boing" sound onto a rock that otherwise would have impaled her mellows her down.
- Denied Food as Punishment: Her quiz to try to get Koichi to learn English. If he answers correctly, he gets normal food, like boiled eggs. If he answers wrongly, she forces him to eat things like rubber erasers or asparagus wrapped in dictionary pages.
- Determinator: When called out on her behavior, she calls it an obsession problem. Once she has her sights set on something, she won't give up until she has it. Unfortunately for Koichi, he becomes her first love. Never giving up eventually works out for her. This trait is also deconstructed to a degree, as while her intense drive and focus imbues her Stand with a staggering amount of power and range, they also blind her to traps she would've otherwise seen coming due to the resulting tunnel vision.
- Early-Bird Cameo: In the anime, she appears in the episode before her official introduction.
- Earn Your Happy Ending: During the "Cinderella Arc", she shows an integrity to her desire for Koichi, finally leading him to return her feelings.
- Expy: One of several Yandere that pioneered its appeal in Japan (she predates the more well-known Yuno Gasai by 14 years), Word of God commentary has admitted that her character was inspired by Annie Wilkes from Misery and the idea of deconstructing the Yamato Nadeshiko. Her hair manipulation abilities and it turning white after combating the person she loves is reminiscent of Lian Nichang from Baifa Monu Zhuan (origin of the "white haired witch" character in many Wuxia films).
- Face of a Thug: When she goes to see Aya Tsuji at her salon, she's described as having a face that would repel love. While she is conventionally quite attractive, there's a certain rigidity to her eyebrows and hard set of her eyes and mouth that some would describe as a "resting bitch face", which makes it especially harrowing to see her when she gets pissed.
- Female Misogynist: She comes off this was considering that she seems to hate all the other female characters she encounters. She nearly kills a female Class Representative who's a supposed love rival, hates Aya after she gets more than she bargained for with her treatments (and while the problem is resolved, it's mainly with Koichi's help), and considers Koichi's mother (i.e. her possible mother-in-law) the last person she wants to encounter.
- Fun with Homophones: "Love Deluxe" sounds a lot like "love the locks".
- Gadgeteer Genius: She builds an electric chair that she intends to use for punishing Koichi. Thankfully, she never gets to use it.
- The Ghost: Unlike with most other Stand users, her Stand, Love Deluxe, is never shown. Of course, it's possible that her Stand could actually be her hair itself.
- Goblin Face: When her Yandere madness reaches its apex, her normally beautiful face contorts into a hideous witch-like one.
- Hair-Trigger Temper: Yukako is very quick to clutch her pearls and give in to anger when she's criticized, which is part and parcel of being a Yandere.
- HeelFace Turn: After her defeat, Yukako, still lovestruck, seemed to have learned from her mistake in trying to force Koichi.
- Laughing Mad: She lets out a pretty crazy laugh when she's strangling Koichi with her Stand.
- Locked into Strangeness: Her hair turns completely white if she uses her Stand too much or if she takes too much damage.
- Ms. Fanservice: Has a pretty face, well proportioned body and a long, flowing raven hair. All of her outfits show off her legs and while being experimented by Aya's Cinderella, she is laying down on a table wearing nothing but a short towel.
- No-Sell: Her obsessive love for Koichi is so ridiculously strong that she can shrug off him using his Stand, Echoes, when it tries to imprint the words, "I hate you!" onto her, making the words on her skin peel off like stickers.
- Official Couple: With Koichi.
- Out of Focus: After the "Yukako Yamagishi wants to be Cinderella" story arc, she is reduced to a very minor role in the RPS Kid arc and completely disappears soon after. She then only appears at the end to salute Reimi.
- Personality Powers: Her Stand is channeled through her long hair, and through her will, it can grab and strangle people. It has a disturbing effect in portraying how ruthless, determined, and controlling she is in regards to Koichi, the object of her affection.
- The Power of Love: Seems to believe in this, if this quote is to go by:Yukako: It doesn't matter if anyone comes, because love is invincible.
- Prehensile Hair: The power of Love Deluxe. She can use her hair as a weapon to do things like use strands to wrap around someone's tongue so they cannot talk, smash though a window so she doesn't cut herself, put some of her hair on someone else's to drag them into things, and just flat out crush a two story house.
- Rapunzel Hair: Even without using her Prehensile Hair to extend the length, Yukako in general has long hair that roughly reaches to her waist.
- Sacred First Kiss: At the end of the Cinderella story arc, she has a Happy Ending with Koichi.
- Sailor Fuku: Has a unique one that's blue and has a rose on the sleeves. What's odd is that in Thus Spoke Kishibe Rohan, she still wears a sailor fuku, despite the story taking place in a time where Rohan owns a smartphone, making Yukako 25 years old at the very least.
- Sexy Santa Dress: A Christmas artwork from an anime staff member features Yukako wearing one. Koichi has a very large blush and is drooling.
- Single Woman Seeks Good Man: The reason why she fell in love with Koichi; he showed that he had a pure and compassionate heart. It ends up driving her to extreme lengths to win his affection.
- Shout-Out: The first question given to Koichi directly namecalls Prince.
- Stalker with a Crush: Towards Koichi, although after he successfully defeats her, she greatly tones down her aggression.
- Tiny Guy, Huge Girl: The huge girl to Koichi's tiny guy. She's officially about 4 inches taller than him, so it's not that large of a height gap, but Koichi is consistently drawn shorter than he actually is.
- Twitchy Eye: She also has the tendency for her left eye to twitch when she is stressed.
- Visual Pun: As she tried to kill Koichi in a rage for destroying her hair, the cliff edge she was standing on fell, making Yukako primed to getting impaled in the back by a rock. But Echoes saves her by making the rock bounce Yukako back like a trampoline. Because of that, that, she fell in love with Koichi again.
- Yamato Nadeshiko: It's played for drama, and also pretty dark. She's beautiful, a good cook, initially comes across as sweet and soft-spoken, and is very dedicated to Koichi. The problem is that Koichi doesn't return her feelings at first and her dedication drives her to kidnap him and forcefully mold him into an "admirable man" by such methods as withholding food and building an electric chair (which she thankfully never gets to use). She also very definitely has an inner steel, but it makes her come across as violently temperamental.
- Long hair was traditionally considered desirable for Japanese women; hers is weaponized. Yamato Nadeshiko strive to improve their husband so he can achieve his goals, but she does it against Koichi's will and consent, heading right into degrading methods. The prerequisite of Undying Loyalty is taken to its full extreme as a Yandere. She is absolutely a Determinator when it comes to love, but when it's unrequited and you stay behind the scenes like Yukako does, it just makes you a Stalker with a Crush.
- Until Echoes defeats her, anyway. More precisely, she initially loves Koichi, but becoming violent towards any who she feels would hurt her chances of captivating him. She takes an overtly psychopathic turn when she decides to kidnap and brainwash Koichi, before his triumphant escape.
- Though she tones down significantly after her defeat, she maintains strong vibes of Yandere, such as continuing to stalk Koichi daily from afar. She even threatens to kill Aya Tsuji for ruining her looks, which Yukkako felt was the only weapon left in her arsenal to win his love. She only shows signs of normality, after Koichi returns her feelings. She is a rare example what happens when a Yandere is convinced to back down and eventually peacefully victorious, yet not cured of the madness that drove her in the first place.
Antonio Trussardi (Stand: Pearl Jam)
Voiced by: Tokuyoshi Kawashima (TV anime), Daisuke Matsubara (All-Star Battle) (Japanese), Christopher Bevins (TV anime) (English)
An incredibly skilled chef from Naples, Italy who sets up shop in Morioh. Shortly into his time there, the heroes learn he is also a Stand user, though he turns out to be a benevolent man. His Stand, Pearl Jam, allows his dishes to correct poor health, though to do so, he needs to understand their conditions, and cook food designed to help them.
- Alliterative Name: In the vein of Lex Luthor, where his nickname fills in for the alliteration: Antonio "Tonio" Trussardi.
- Anime Accent Absence: Unlike other Italian characters in the series, he averts this; in the anime he has a distinctive accent when he speaks, indicating that Japanese isn't his first language. The English dub makes a strong effort to keep the accent as well.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; He's just gotten finished serving Yuya and his girlfriends while Okuyasu, his dad, and Stray Cat are all enjoying his Pasta Puttanesca (which was part of Okuyasu's first meal there).
- Bait-and-Switch: Josuke, sneaking in his kitchen after he suspects something is up with him, sees him feeding one of his meals to a small dog grinning like a loon when the dog explodes. Tonio then attacks Josuke by throwing him kitchen knives and screaming when he spots him... Turns out the dog was suffering from diarrhoea like Okuyasu so Tonio gave him extra food, the dog is perfectly fine, his "explosion" being due to Pearl Jam's curing effect, and he's mad because Josuke messed up his kitchen's hygiene.
- Berserk Button: Kitchen hygiene is something that Antonio takes very, very serious; He does not take ignorance of said hygiene well, either, as Josuke found out.Antonio: You touched things without washing your hands, didn't you!? The number one enemy in a kitchen is germs! That's why I got angry! (gives Josuke a brush, bucket and bottles of disinfectant)
Josuke: H-Huh? I-I'm sorry! I-I didn't mean it!
Antonio: You'd better prepare yourself!
- Beware the Nice Ones: He's overall a really pleasant guy. Act rude towards him and disregard his kitchen hygiene though, and he'll get very upset at you, as Josuke found out before being forced to clean the kitchen. Before that, he throws a knife that barely missed Josuke's head.
- Body Horror: While his cooking is purely beneficial, its healing effects look very gross while in action, causing Okuyasu's eyes to deflate and a dog to start puking up its intestines. Downplayed in that they're both back to normal shortly after, and in better shape than they were before.
- Dub Name Change:
- Pearl Jam is changed to Opal Jam in the English version of All-Star Battle and Pole Jam in Crunchyroll's subtitles for the anime. In the English dub of the anime, it is simply unnamed.
- All official English versions change his last name from Trussardi to Trendy, presumably to avoid legal trouble from the real life fashion house.
- Face of a Thug: Pearl Jam looks like a swarm of grimacing, sharp-toothed parasites made of vegetables, but it cures the illnesses and pleases the taste buds of Tonio's customers. Tonio himself can look and sound rather threatening when he exposits about his food, which is one reason why Josuke thought him a villain before learning the full truth.
- Healing Magic Is the Hardest: His Stand can cure diverse illnesses and conditions perfectly in seconds, but it has a lot of conditions. First, he needs to know the illness in advance because each dish can only cure one. Second, he needs specific ingredients. Third, he needs a clean kitchen and sufficient time in order to produce the dish. In comparison, Josuke's Stand is more user friendly but also more limited in application, seemingly being limited to healing physical injuries.
- He Knows Too Much: Subverted. It looks like he's flying into a rage when Josuke and Okuyasu see his apparent Kick the Dog moment. Turns out he was just pissed that they didn't come in with the proper hygiene, and they then see that he was in fact helping the dog recover from bad diarrhoea.
- Hyperactive Metabolism: Invoked by his Stand in the dishes he makes.
- Impossibly Delicious Food: Okuyasu exclaims that every dish he tries is mind-blowingly tasty; the best he's ever had by far. Even the mineral water gets him raving about it like a professional gourmand.
- Logical Weakness: As detailed below, Pearl Jam can only help people if Antonio actually knows what their symptoms are, and even then he needs to make food that actually helps with the healing process. If someone has relatively common or normal health issues like Okuyasu did, he can usually make something easily that will help them. However, rare health issues are much harder to cure because he needs to actually understand what the cause of it is. This is why in the finale of the anime, his cooking doesn't cure Okuyasu's father, since he presumably doesn't know the full extent of his condition. Also, the basic rules of cooking affect his Stand as well; his food needs to be made right to work.
- Magic A Is Magic A: Pearl Jam is not a "cure-all" power that heals everything in one go; each dish Antonio makes is specifically designed to cure one malady each. The amount of unique, high-end ingredients he'd need is also directly proportional to the difficulty in normally recovering from the ailment, to the point where he's had to illicitly acquire prohibited ingredients for some of his dishes.
- Maybe Magic, Maybe Mundane: It's not clear if his cooking's overwhelming deliciousness is a result of his long time experience as a chef, or if it's a secondary effect of Pearl Jam.
- Nice Guy: Pretty much the only Stand user the heroes run into that through and through has good intentions, with no Defeat Equals Friendship required. If anything, Tonio defeated Josuke.
- Personality Powers: Pearl Jam was awakened by his resolve to perfect his culinary arts, and its ability reflects that; it quickens the body's digestion and utilization of food to repair any diseases or other conditions the eater is suffering from, no matter how major or minor, with the right dish/ingredients.
- Panacea: His Stand's abilities can make food that cures any disease, though not without some weird side effects. However, it has its limits in that every disease needs a specific dish, and curing rarer ailments needs rarer ingredients.
- Required Secondary Powers: Antonio seems to also have the ability to divine a person's ailments through palm reading so as not to rely on guesswork when preparing a plate, as he needs to prepare a specific dish for each one. Likewise, Pearl Jam needs to be added to the correct food in order to cure a specific health problem; one of the non-canon light novels have him illegally harvest rare sea snails to cook a meal able to cure cancer.
- Serious Business: As mentioned from the Berserk Button above, personal hygiene is something that he really takes very seriously. If you caught red-handed touching something from his kitchen without washing your hands, be prepared to clean it all very thoroughly.
- Sheep in Sheep's Clothing: At first glance, Josuke is rightly suspicious of him for the Body Horror his food inflicts on those who eat it, and thinks Tonio could have a hidden agenda in serving that kind of food. But as it turns out, he's genuinely trying to make his customers happy and healthy.
- Stealth Pun: Pearl Jam has a fitting name; not for its musical reference, but for its resemblance to pearl onions.
- Supreme Chef: Tonio is a master of Italian cuisine and only uses the best ingredients.
- Verbal Tic: Along with occasionally slipping Italian into his speech, Tonio uses the word "anata" a lot, which is a common mistake by non-native speakers of Japanese who are used to second-person pronouns being used more often.
- What You Are in the Dark: Thus Spoke Rohan Kishibe - Poaching Reef gives a bit of background for Tonio's reason to migrate from Italy to Morioh. He wanted to find a cure for his lover's tumor, which is such a rare malady that Pearl Jam needs an extremely rare ingredient from Morioh's waters in order to cure her.
Shizuka Joestar (Stand: Achtung Baby)
Voiced by: Taeko Kawata (TV anime JP), Kaitlyn Robrock (TV anime EN)
An invisible baby found by Josuke Higashikata and Joseph Joestar. Her Stand ability, "Achtung Baby", allows her to turn her and anything at short range invisible.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; As was explained in the manga, she got adopted by Joseph, but the anime omits the part about Suzi Q's reaction to him bringing another child that isn't hers home.
- Blessed with Suck: The ability to turn yourself and nearby things invisible sounds like a useful power, right? Well, it's not so useful for a baby who can't control when and what she turns invisible, as it makes it nearly impossible to take care of her, which Josuke and Joseph find out when she falls into a lake and nearly drowns.
- Chuck Cunningham Syndrome: Despite being adopted by Joseph at the end of part 4, she hasn't appeared in any of the later parts.
- Invisibility: Her Stand ability, "Achtung Baby", allows her to turn her and anything at short range invisible. Depending on stressful situations for Shizuka, the active strength of the Stand can increase making the immediate surroundings of the child invisible as well, be it a person's fingers, her baby carriage or even the ground.
- Meaningful Name: Shizuka means "calm" or "quiet"; both appropriate for someone with a stealth-themed Stand, and something her caretaker is going to hope for, as her ability causes trouble if she gets upset. Her first name can also be read as "Jo". Going with the adopted family name, her name can be read as "Jo Joestar".
- Missing Mom: Her mother's identity was never discovered, thus she was adopted by Joseph. Whether her mother abandoned her or her mom was one of Kira's victims is left to the viewer's thoughts.
- Power Incontinence: She can't fully control when (and what) she turns invisible with her Stand. As a result, her body is permanently invisible, and her clothes, makeup, and other nearby objects also start to vanish when she's under great stress. Unfortunately, this means that taking care of her can be extremely difficult. Justified, since she is just a baby and has no control of her power yet.
- Practically Different Generations: Due to being adopted by Joseph, she's the adopted sister of Josuke and Holy despite being 16 and 57 years younger than them.
- Shout-Out: The "disguise" that Joseph and Josuke gives her might be a reference to The Invisible Man.
Shigekiyo "Shigechi" Yanguu (Stand: Harvest)
Voiced by: Kappei Yamaguchi (TV anime, All-Star Battle, Eyes of Heaven), Brian Beacock (English)
A fat middle schooler with a greedy streak. He commands Harvest, a 500-man Stand resembling tiny bee men.
- Acquired Situational Narcissism: The joy of having friends and the belief that he deserves most of the credit for his, Josuke's and Okuyasu's Get-Rich-Quick Scheme quickly goes to Shigechi's head, and causes him to go from being meek and childish to arrogant and greedy.
- Ambiguous Disorder: Not particularly bright, has problems with social skills, and generally acts like someone at least five years younger than he is.
- Anime Hair: Those weird spikes in his scalp were originally hair, but it just got sort of lost in promotional material and subsequent recolourings.
- Crouching Moron, Hidden Badass: While not very smart and seemingly harmless, Shigechi shows himself to be a surprisingly cunning and underhanded fighter. His Stand is rated E for Destructive Power, but Shigekiyo's instinctive mastery of the Harvest causes him to be considered by the heroes as one of the most powerful Stand Users in Morioh.
- Cruel and Unusual Death: His face and body is partially caved in by Killer Queen's first explosion (to the point part of his nose is pushed into his brain), and stumbles around in pain for a while before being finished off. This is even more pronounced in the anime, where he suffers for half the episode before being put down.
- Death of a Thousand Cuts: One application of his Stand is for them to inflict countless little gashes which quickly add up, or they can target blood vessels like the carotid artery.
- Determinator: Takes Killer Queen's bomb and can still talk and command his Stand. Sadly, the second one finishes him off.
- Dying Clue: He manages to pull off a distinctive button from Kira's suit and manages to get the last of Harvest to deliver it to Josuke and Okuyasu just as Kira finishes him off.
- Even Bad Men Love Their Mamas: He's a selfish money-grubber, but when Kira threatens his parents after damaging him heavily, he spills the beans about Morioh's search for Reimi's killer.
- Fat Bastard: While he is one of the good guys, Shigechi is also greedy, quick to blame his friends when something goes wrong, and has a tendency to go back on his word once he has what he wants. Justified in that he hasn't exactly been treated nicely in the past.
- Fatal Family Photo: Shigechi casually showed a picture of his own mom in his introductory arc... and ends up getting killed in the next one.
- Gonk: One of the ugliest characters of the entire franchise. He's short and fat. Apparently bald, his crown is textured by short spikes, and he has thick, drooping earlobes. He has small, high eyebrows and youthful features. His teeth are misaligned, and he is missing his left maxillary central incisor.
- Greed: Shigechi's greediness and possessiveness get the better of him at times. He couldn't bear the thought of sharing the five million yen he, Josuke and Okuyasu acquired through the lottery with them, stealing the check from them by force and threatening to kill both if they approached. After his eventual reconciliation, Shigechi's possessiveness still extends to being unwilling to freely give any amount of money to his friends, as he insists it's a loan and keeping records of the transactions, with the full expectation of getting that money back by the next day. He also becomes very touchy when someone threatens his lunch. This in part gets him killed.
- Heart Is an Awesome Power: One of the best examples in the series. Shigechi's Stand seems like nothing special, being just a bunch of tiny creatures with a stinger that has practically nil offensive capability, and with a little compartment in their head in which they can store anything that fits, which is not much. However, multiply that tiny offensive capability by five hundred and give it an astounding range, you actually have a potentially pretty dangerous Stand, and he can also command his Stand to look for things to bring him which manage to fit in their head, such as coins, and they're all intelligent enough to find what Shigechi wants every single time.
- Additionally, his introduction arc shows that Harvest's stingers can function as syringes, as seen when he discreetly injects Josuke and Okuyasu's veins with hard liquor to get them swiftly drunk and disoriented. If he were so inclined, Shigechi could kill people easily by injecting them with any number of nasty chemicals, or simply causing embolisms by putting air bubbles into their bloodstreams.
- He Knows Too Much: One day, he buys an expensive sandwich made in limited quantities each day. He misplaces it and finds another bag from the same bakery. Unfortunately, Yoshikage Kira also bought and misplaced the same sandwich and left his current "girlfriend" in the bag. Shigechi finds Kira's sandwich bag and eventually discovers his "girlfriend", so Kira kills him because he cannot leave any witnesses alive.
- Hope Spot: When he manages to get to Josuke's classroom after being critically injured by Kira, it turns out Kira got there before him and turned the doorknob into a bomb.
- Microbot Swarm: Harvest is a collection of small android-looking bugs that Shigeshi uses to collect coins through town. However, they can form a swarm for offensive attacks or to carry him around, even to vertically crawl up walls. This is especially evident in his videogame appearances in All-Star Battle and Eyes of Heaven.
- The Minion Master: Harvest is one of the few Stands composed of many small units that may act individually. The number of individual units comprising Harvest totals about 500.
- Mundane Utility: He uses his Stand to collect all the lost coins around town. This sounds rather pointless until you do the math; if he commands them to go find 100 yen coins, it means he'll get back five hundred of those. That's roughly $500 USD, which he can ask the Stand to bring him pretty much at will. Him getting those five hundred 100 yen coins every day would set him for life, and he's doing it without committing a single crime.
- With advice from Josuke and Okuyasu, he's able to utilize Harvest to reap bigger rewards such as promotional store coupons and by sheer luck, a winning lottery ticket.
- No Body Left Behind: As a victim of Killer Queen, his body gets incinerated completely.
- Personality Powers: He is a greedy little boy with a Stand that can easily and swiftly gather hundreds of small objects at a time.
- Rasputinian Death: Notably, not due to how creative and drawn-out his death is, but the fact that he survives getting blown up by Killer Queen, and it takes a second detonation to finally kill him. Even then, his soul persists just long enough to let his final Harvest provide the clue that sets the heroes on Kira's trail.
- The Scrooge: Shigechi is immensely miserly, and refuses to share the spoils of Harvest's work with anyone if it's a big prize.
- Signature Laugh: "Shi shi shi." Borders on Pokémon Speak.
- Simpleton Voice: High-pitched and childish. In the Japanese version, he also talks in rather childish and simplistic manner.
- Small Role, Big Impact: He only shows up in two arcs, his introduction and his fatal meeting with Yoshikage Kira. The latter ends up finally giving his friends a lead on the serial killer.
- Spanner in the Works: Kira is so cunning that the cast most likely would've been spinning their wheels for a long time trying to find him if Shigechi hadn't stumbled onto him by sheer accident and gotten himself killed trying to tell the others. In fact, the Speedwagon Foundation would not have gotten involved as the heroes weren't sure the killer was a Stand user or not, and Jotaro and Joseph were on the verge of leaving Morioh due to lack of Stand-related evidence.
- Synchronization: Much like Keicho, because his Stand is represented by five hundred separate bodies, damage or destruction of one or two bodies doesn't seem to do anything to Shigechi himself. Also, after his death, his one surviving Harvest Stand arrives in front of Josuke, and explodes in much the same way as Shigechi did.
- Walking Spoiler: His death introduces the Big Bad of Part 4.
- We Hardly Knew Ye: He is killed in the chapter after his introductory arc. The anime spreads out his introductory arc and death.
- Weak, but Skilled: A shining example of the trope. Although physically weak, Harvest is incredibly versatile: it's fast, has a huge range, and can multitask to an absurd degree thanks to its 500 bodies; that also means fighting it directly is impossible since the loss of a few bodies don't make the slightest dent in the Stand as a whole. Coupled with Shigechi's great cunning and underhandedness in a fight, and it's hardly an exaggeration when Josuke says he can't imagine anyone capable of defeating it.
- The Worf Effect: Josuke interprets his defeat as evidence that their enemy is an incredibly powerful Stand user.
Aya Tsuji (Stand: Cinderella)
Voiced by: Sayaka Ohara (Japanese), Katelyn Gault (English)
The manager and chief beautician of the Cinderella spa. Aya considers herself the fairy godmother of any woman who wanders into her salon, and uses her stand, Cinderella, to temporarily alter these women's appearance in a way that will magically attract luck and love.
- Adaptational Early Appearance: Downplayed example. Her debut story arc in the manga, Yukako wants to be Cinderella, was after Yoshikage Kira Wants a Quiet Life, but since those episodes' orders were reversed in the anime, Aya appeared with the gang after Shigechi's death, with some dialogue foreshadowing future events. Other than that, her role remains the same.
- Ambiguously Gay: When Yukako comes back for another 30-minute treatment, she acts rather... odd.Aya: I'll need to touch you in all sorts of places...
- Basically she just feels her lips and lowers Yukako's shirt, which isn't bad, but then out of nowhere, she just grabs Yukako's breasts. It's kinda funny that Yukako doesn't even react, but she does slap her whilst stonefaced.
- It also says something that in response to getting slapped, she just giggles.
- Art Shift: When she appears in the anime, the style shifts to Art Nouveau to mirror how fairy tales (such as her Stand's inspiration) were illustrated.
- Chekhov's Gunman: Initially a supposedly random Stand User encountered by the heroes like Tonio, her Stand's ability to change a person's appearance drives the plot of the Part's second half.
- Distaff Counterpart: Aya is this to "Tonio" Trussardi. A somewhat quirky, but otherwise peaceful, benevolent Stand user who only uses his/her Stand powers to run a business for the sole purpose of bringing happiness to his/her customers (and making a living out of it).
- Dropped a Bridge on Him: She gets detonated by Kira so she can't reveal how she altered his features and so they won't revert. Note that said detonation occurs very shortly after the heroes find her after Kira's escape from her shop.
- Fairy Godmother: How she sees and acts herself.
- Fairytale Motifs: Her Stand Cinderella, due to Aya taking inspiration from the fairy godmother of the eponymous tale.
- His Name Is...: Gets blown up by Kira just before she could reveal the name of the man whose face he stole.
- Jackass Genie: While her Stand does inflict Body Horror on Yukako, she notes that it was because she didn't continue to apply the lipstick she was given.
- Magic Plastic Surgery: Done through Cinderella, it pretty much is magic. The Stand can replace some parts of your body by creating a replacement for it from the slots on its hand. It can also remove body parts from existing humans and place them on others.
- Mundane Utility: Cinderella was awakened due to Aya's desire to be like the Fairy Godmother from the story. When Cinderella alters a woman's features, it also amplifies her luck while the features are in effect. This includes gaining Mr. Right.
- No Ontological Inertia: Inverted. The effects of Cinderella will go away in 30 minutes...unless you kill her.
- Personality Powers: See Mundane Utility.
- She Knows Too Much: Kira goes to her to change his appearance, and then kills her because she knows what his new face looks like.
- Take a Third Option: Aya gives Yukako the chance to restore her deformed face if she can identify her face among dozens of faces. The truth is that none of the faces are Yukako's; only if she realizes this will Aya fix her face. Yukako takes a fourth option and asks Koichi to choose for her, saying that she will be satisfied with his choice. Furthermore, when Koichi requests to be blinded in case Yukako ends up ugly to ease her pain, Aya is so moved by the couple's love for each other that she restores Yukako's features anyways.
- Tempting Fate: The anime has her declaring she will keep an eye on her customers, even though there is no reason for the killer to go there. She is wrong.
- Verbal Tic: Tends to end her sentences with a visible sigh or heavy breathing sound because of her naturally low blood pressure.
Mikitaka Hazekura / Nu Mikitakazo Nshi (Stand(?): Earth Wind and Fire)
Voiced by: Yasuyuki Kase (TV anime JP), Mark Whitten (TV anime EN)
His ability is named after the R&B/Disco group Earth, Wind & Fire.
- Acting Unnatural: While posing as a trio of dice to help Josuke cheat against Rohan in a gambling game, he gives Josuke the best possible dice combination twice in a row (three sixes) and gives Rohan the worst possible dice combination (one, two, and three, an instant lose condition), making it blatantly obvious that Josuke is cheating.
- Adaptation Dye-Job: Is white-haired in the manga, but is platinum blonde in the anime.
- Ambiguously Human: He claims to be an alien, but it's never confirmed. By the time of Thus Spoke Kishibe Rohan, his friends have largely given up refuting his extraterrestrial notions and just refer to him as an alien.
- On one hand: his shapeshifting ability is peculiar, even for a Stand; it's not even clear if it was granted by the Arrow, since it practically bounces off of him, not to mention that he doesn't react to Crazy Diamond almost punching him — implying that he lacks a Stand. He has pointed ears, and is "allergic" to the sound of sirens, bursting into hives all over his body if he hears them. And, he's barely aware of normal human behavior, not knowing what money, dice, and tissues are.
- On the other: Earth Wind and Fire is given Stand stats, so it could be reasoned that it's just a Stand and Mikitaka is feigning ignorance of Crazy Diamond's presence with his consistently calm demeanor. The pointed ears and allergy to sirens could just be him using his Stand to alter himself, or, given how many people with Stands have strange physical attributes, could be something he naturally has. Finally, he has no knowledge on normal human customs, but is aware of enough of them to be able to accurately replicate ice cream and binoculars without in-depth descriptions; that might just be him slipping up on the act.
- Perhaps the biggest giveaway is Mikitaka's mother. One of the first things she does (in the anime only) is complain that Mikitaka is still trying to assert himself as an alien. Mikitaka explains to Josuke that he hypnotized her into thinking she was his mother, but how and why he did so is left unknown.
- Alien Among Us: Mikitaka claims to be an alien living among humans. It's ambiguous whether or not he's telling the truth, but if indeed he is an alien, the world shown in JJBA is so weird and chaotic that his unusual appearance, eccentric demeanor, and weird powers actually do nothing to prevent him from blending right in. It helps that he's a Rubber-Forehead Alien living in a world where humans typically look at least a little extraordinary, and his Voluntary Shapeshifting abilities are small potatoes compared to the Lovecraftian superpowers frequently displayed by many Earth-born characters.
- Alien Blood: Averted and Lampshaded. He has red blood, but Josuke and Okuyasu point out that alien blood is always green.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; He and Toyohiro are hanging out inside Superfly, with Mikitaka remarking on what an interesting town Morioh is from his (probably) non-human perspective.
- Bishōnen: After Art Evolution kicks in; his ears become slimmer and don't stick out as much, his hair gains a lot more volume and flows freely opposed to being pulled back tightly from his face.
- Cloudcuckoolander: Even if he really isn't an alien he would be a really strange boy.
- Dub Name Change: Earth Wind and Fire to Terra Ventus in the English version of All-Star Battle and the Crunchyroll subs.
- Early-Bird Cameo: Can be seen among the crowd when the heroes tried finding Kira the first time.
- Feel No Pain: Even after having his arm bolted to a steel tower he doesn't flinch a bit, just seems a bit confused.
- Friend to All Living Things: His hobby is taking care of animals, and even after Josuke didn't believe his identity as an alien and Okuyasu acted hostile towards him he still tries to be friendly and help them. He willingly accepts his fate as Superfly's prisoner if it meant keeping Josuke safe. Not that Josuke was having any of it, though.
- Happily Adopted: He clearly cherishes his adoptive(?) human mother even though he also claims that he altered her memories to make her believe that he's her son.
- Healing Factor: He seems to possess regeneration, as Mikitaka transforms part of his hands into ice-creams and separates them from his body, but nothing is missing from his hands later.
- Knight of Cerebus: Inverted. The arcs Mikitaka is featured in are notably much more light-hearted and comedic than the otherwise serious arcs of the Part's second half.
- The Masquerade: He claims that he is maintaining this in front of his mother.
- Mundane Utility: Josuke asks to turn into some rigged dice, and uses him to play dice with Rohan in order to cheat some free cash out of him.
- Mystical White Hair: He has very long and beautiful white hair, which, given his age might indicate his alien heritage.
- Nice Guy: If the interpretation that he isn't just pulling a big prank on everyone is correct, then he's easily one of the kindest characters in the Part. Mikitaka is always in a pleasant mood, likes taking care of animals, and happily throws himself into the fray when it looks like Josuke is going to be trapped.
- Not So Stoic: He's almost always serene and calm; being hit with Super Fly's reflected energy barely produces any reaction of shock from him. If sirens are present, however, he goes nuts trying to get away from the sound, yelling and screaming for Josuke to bring him somewhere quieter.
- Pointy Ears: Serve as an indication that he may or may not be human. No one else has pointed ears.
- Really 700 Years Old: He claims to be 216 years old, despite how he looks to be around the same age as Josuke and Okuyasu.
- Riddle for the Ages: Is he really an alien or just a Stand user who likes to think of himself as such? The story never really answers on it and just keeps it ambiguous with it even later stated by Josuke that they've long since stopped trying to figure it out and humor the guy for the sake of friendship.
- Rubber-Forehead Alien: If he is an alien, he looks mostly human except for his pointed ears.
- Voluntary Shapeshifting: Stand or an alien ability, this allows him to transform into almost anything. He seems to be able to combine his strength with those of other people: when he turned into sneakers for Josuke to wear, he notes that their strength combined is what made them able to move away so fast. Although he can transform into almost any object, he is unable to transform into complex items like machines or something that requires more strength than his own to operate (i.e. dynamite) and copy the appearances of other people (he claims it's because all humans look the same to him).
- Weaksauce Weakness: The sounds of sirens cause him to break out and lose control of his powers, leading to the very memorable scene of him splitting apart into ribbons while wailing for Josuke to take him away from the noise.
Yuya Fungami (Stand: Highway Star)
Voiced by: Kissho Taniyama (TV anime JP), Phillip Reich (TV anime EN)
A biker gang Japanese Delinquent whose good looks and charismatic charm has earned him the adoration of three women. His Stand is the Life Drain-causing Highway Star, capable of sustaining speeds up to 60 kilometers per hour without tiring and dividing into a swarm of footprints to drastically increase its durability.
His Stand is named after the song "Highway Star" by Deep Purple.
- Adaptational Badass: Downplayed. While his Big Damn Heroes moment during the Enigma Arc is largely the same (he deliberately triggers Enigma's power in order to turn himself to paper to rescue Josuke and Koichi), the anime changes how he goes about it slightly. In the manga, his victory came in part by an oversight by Terunosuke as Yuya's proximity to the paper forms of Koichi and Josuke allowed them to be attached to him, letting him pull them out, but in the anime, this is instead changed to Yuya utilizing Highway Star's abilities in a more creative way by having Highway Star detach and extend himself whilst being turned into paper to grab the pair and pull them out. If anything, it does make his rescue more dynamic.
- Ain't Too Proud to Beg: Infamously tried to hide behind his injuries to spare himself a further beating from Josuke. Josuke promptly healed him with Crazy Diamond.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated; He and his girlfriends have just finished up a meal at Tonio's, and are all remarking on how refreshed and vibrant they feel.
- Balanced Harem: His three girlfriends seem to be perfectly fine with sharing him, and he in turn genuinely seems to love all of them.
- Be Careful What You Wish For: Desired a quick remedy to his injuries, which influenced the power his Stand achieved. Josuke granted him his wish and then made it so that he could never use Highway Star for that purpose again under threat of an even longer and more painful hospitalisation.
- Beauty Equals Goodness: As a Villain of the Week, he's an Evil Cripple, trapped in full-body bandages as he steals life force to become mobile again. After Josuke recruits him to take on Enigma and heals his wounds to do so, Yuya regains his full mobility, and he proves himself a good person by saving Josuke and becoming one of his friends. That being said, due to the nature of Araki's art style, he was never exactly ugly, just infirm.
- Body Motifs: In contrast to the ever-present hand motifs in Part 4, Yuya has a noticeable foot one, fitting as much of his first arc revolves around ambulation. Highway Star breaks itself down into feet which it uses to chase people, Yuya is introduced feet first when he's seen at the hospital, and it's clear that he's trying to regain the mobility that his accident cost him.
- Blonde, Brunette, Redhead: His admirers in the anime incarnation, as one of the girls was modified to have red hair.
- Chick Magnet: Is continually attended by three girls in love with him. The fight with Enigma shows that the feeling is mutual.
- Detachment Combat: Highway Star can break his body down into dozens of small feet to rush a target. It proves useful against Koichi, who can only attack one at a time, and in the anime, it's used to great effect fighting Enigma, where as he's being turned to paper, Highway Star detaches and extends his arm far enough to rescue the similarly paper Koichi and Josuke.
- Dub Name Change: Highway Star to Highway Go Go in the English dub—possibly referencing The Go-Go's.
- Early-Bird Cameo: He can be seen in a shot among the crowd when the heroes are tracking down Kira the first time after stealing Kosakus face.
- Explain, Explain... Oh, Crap!: He tries to weasel out of being pummeled flat by asking Josuke if he would really hurt someone who is already injured. Josuke tells him his wounds have already been healed, before asking right back if it would still be unsportsmanlike. It takes Yuya a moment to catch on, but the Oh, Crap! comes sharp.
- Fangirl: He has three girls that love and protect him while he was hospitalized, not letting anyone come closer. Their names are Reiko, Akemi and Yoshie.
- Fighting a Shadow: His Stand can section itself into many parts as it flies at its extreme speeds, breaking apart in flat horizontal segments and moving, then reassembling piece by piece. This allows Highway Star to do things like slip through narrow passages or do large scale multiangle attacks by striking with all its pieces at once.
- Full-Frontal Assault: Highway Star, unlike most other humanoid Stands, is completely lacking in anything that resembles armor or clothing, leaving its Barbie Doll Anatomy easily visible to all.
- Gorgeous George: With a face like that, it's no wonder why those three girls are all over him almost 24/7.
- HeelFace Turn: When Koichi is kidnapped by Terunosuke Miyamoto, Josuke asks him to find Koichi with his heightened sense of smell, but Yuya warns him that this is the only thing he will do. They find Terunosuke and Josuke is turned into a paper by Enigma. Inspired by Josuke's bravery in his attempt to save Koichi, Yuya thinks about how he would do the same for his admirers and saves Josuke and Koichi.
- Hidden Depths: Yuya is a really good detective, as evidenced by his deductions with his advanced sense of smell. This is why Josuke enlists him in fighting against Terunosuke.
- It Can Think: Highway Star is able to move and think independently even conversing with the heroes and coming up with plans on its own. When going after Terunosuke Yuya gives orders to Highway Star rather than simply controlling it with his mind.
- It's All About Me: Sure, he's taking his victims to the very brink of death and maybe even beyond, but he's just in such bad shape.
- Averted when it comes to his fangirls. After seeing Josuke fall for Terunosuke's trap because of the non-zero chance that the decoy paper he threw into traffic did have Koichi inside, he mentally admits that if it were one of his girls, he'd do the exact same thing.
- Japanese Delinquents: Part of a biker gang; he got his Stand when Yoshihiro's arrow caused him to end up in a massive auto accident. The three girls who are in love with him are also delinquents, wearing long skirts and carrying wooden swords around.
- Jerk with a Heart of Gold: His introduction shows him to be an arrogant punk who is willing to drain other people's life forces for his own benefit, but he's later shown to be a decent guy at heart. In particular, he doesn't hold a grudge, will uphold his end of a bargain, and genuinely loves his harem.
- Lantern Jaw of Justice: He's got quite a distinctive square jaw which is further highlighted by his tattoos.
- Life Drain: Highway Star can steal the nutrients of a victim and transfer it to Yuya. This process accelerates his healing. Josuke managed to recover from being drained by drinking the contents of a saline drip.
- Lightning Bruiser: Highway Star is fast enough to catch anything going slower than 60 km/h, instantly incapacitates on contact with its target by sucking out their nutrients, and unstoppably durable when in its swarm form, in addition to having a range spanning the entirety of Morioh.
- Narcissist: His first action upon having his injuries healed is to admire how handsome he is in the mirror, then complain to Josuke (the person who healed his injuries) about his eyes being droopier than he remembered.
- The Nose Knows: He has a strong sense of smell, which is shared with his Stand. He can tell if a peach has gone bad from across the room and track a person down by scent.
- Oh, Crap!: Fungami is initially surprised that a pissed-off Josuke would actually heal him instead of beating him up, but that surprise on his face turns into sheer terror once he realizes his hospital stay will be extended, courtesy of Crazy Diamond's fists. Then again, it would be cowardly to beat up a poor, hospitalized guy with a broken spine, wouldn't it?
- One to Million to One: Highway Star's capability of separating into feet to chase others. Doing so makes it incredibly resilient, able to take Crazy Diamond's barrage of punches multiple times yet not slow down nor transfer its damage to its user; as a tradeoff, it cannot move intelligently in this form, always moving straight towards whoever it is tracking, even if there's something like a wall in the way.
- Personality Powers: Both of Highway Star's primary traits — that is, travelling at fast speeds and healing its user with stolen nutrients — match Yuya's character of being a biker that just wants to get out of the hospital.
- The Pirates Who Don't Do Anything: We never get to see him touch a motorcycle, nevermind being a motorcycle racer or part of a biker gang. Not even during the Enigma Boy arc, where Terunosuke drives away in a car and Yuya runs offscreen... then appears where Terunosuke's taxi stopped in the Morioh countryside, sans vehicle, implying that Yuya ran the whole way there. Justified, since he just got out of the hospital, and his motorcycle was probably wrecked from his accident.
- Rapid-Fire Fisticuffs: In the anime he attempts to unleash this on a paper shredder. While Highway Star has the "rapid fire" part down, that C-tier destructive power means Yuya's not much better off compared to attacking it with his bare fists.
- Required Secondary Powers: In its first appearance, Highway Star had the ability to create the illusion of a room, which Yuya uses to lure Rohan in. He never uses this ability again.
- Rubber-Band A.I.: His Stand normally has a maximum speed of 60 mph, but can teleport to a close proximity of its target if they get too far ahead of it as well.
- Screw This, I'm Outta Here!: Tries to bail out of the Enigma fight after Josuke is trapped by the Stand's power, though this is immediately averted.
- Signature Sound Effect: Multiple in the anime; the squeaky bare-feet-on-hardwood when it chases something in its footprints form, the constant sniffing it makes when tracking opponents, the rapid-fire synthetic clicks when it attacks, and the low "bloop" when it turns back to its humanoid form or teleports.
- Smug Snake: In his defence, Josuke did look pretty defeated when they finally met face to face. The trait even extends to Highway Star, who was pretty arrogant throughout his assault on Rohan and Josuke up until he and his user both learned the hard way that Crazy Diamond's punches are much much faster than 60 km/h.
- Stealth Pun: His Stand has enhanced olfactory abilities and can split itself into a swarm of footprints to chase its target. That is, it can become a bunch of feet that smell. Smelly feet, if you will.
- Super-Persistent Predator: His Stand is capable of constantly chasing someone at up to 60 km/h and has a range that could reasonably span all of Morioh, if not even further.
- Tattooed Crook: He bears a tattoo of his Stand's initials on his chin, and given the conditions of getting his Stand leaving him in the hospital, he almost certainly received it before naming Highway Star. His girlfriends also have the same tattoo on their upper arms.
- Took a Level in Kindness: Was first a spoiled Jerkass when he was the Villain of the Week of his respective arc, but after being forced to be allied with Josuke, he starts to care about other people, and even arrives to say goodbye to Reimi; the end of the anime also shows him bringing his fangirls to Tonio's restaurant.Josuke: "Yuya Fungami... you're actually kinda cool, after all."
- Ungrateful Bastard: Has the gall to complain to Josuke about his eyes being droopier than before after the latter heals his entire body. That said, he follows through with his end of the deal that made Josuke heal him in the first place, so he's not all bad.
- Vampiric Draining: Highway Star breaks down a person's body by draining the nutrients from their cells; its user Yuya uses the stolen nutrients to help him recover from grievous wounds suffered in a motorcycle accident.
- Visual Pun: Highway Star usually goes after targets as footprints via smelling out their scent i.e: Smelly Feet.
Yoshikage Kira (Stand: Killer Queen)A seemingly ordinary man, who turns out to be a Stand-wielding Serial Killer. See Yoshikage Kira.
Anjuro "Angelo" Katagiri (Stand: Aqua Necklace)
Voiced by: Kenji Hamada (TV anime, JP), Lex Lang (TV anime, EN)
Played by: Takayuki Yamada (live-action movie)
A serial killer and the first villain of the story. Carries the Stand Aqua Necklace, who can travel through any liquid body and kill people from their insides.
Aqua Necklace is named after the album Aqua by Asia.
- And I Must Scream: His fate after Josuke melds him into a boulder.
- Ax-Crazy: His response to a dog pooping near a tree and its owner throwing cigarette butts on the ground is to bite the dog's face off and spit it into its owner's mouth. And that's one of his tamer moments.
- Back for the Finale: Kind of, but Koichi and Yukako meet up for their date in front of him as the Angelo Stone, which was stated to be a popular place for young lovers to meet despite its appearance.
- Catchphrase: Likes to tell his opponents not to get cocky.
- Depraved Bisexual: His crimes include raping women and a trio of 14-year old boys (though seeing as they were underage, he could be straight but with hebephilic urges).
- Dirty Coward: When he's outsmarted by Jotaro and Josuke, he panics and runs like hell, and pathetically begs for mercy when he's cornered. This man is a Serial Rapist who targets women and children, did you honestly expect him to be brave?
- Disproportionate Retribution: His habit of holding deep grudges over minor transgressions and his extremely good memory makes him a terrifying criminal.
- He also takes the Jojo staple of Bad People Abuse Animals to a new level by brutally biting off a dog's nose and spitting the bloody mess into the owner's mouth before killing him for not picking up his dog's shit, which Angelo stepped in earlier, and tossing aside a used cigarette.
- Evil Genius: Jotaro says that he has an IQ of 160. He's also smart enough to use the weather and environment to his advantage when fighting both Josuke and Jotaro.
- Even Evil Has Standards: Though highly doubtful one could call this an actual standard nor does he give the appropriate response to it, but he apparently doesn't like it when people do things like carelessly leaving dog poop or cigarette butts on the ground.
- Evil Is Petty: Brutally murders a dog and its owner under the pretense of it pooping carelessly. However, it's clear that he's venting his rage on them because his attempt on Tomoko's life failed.
- Evil Sounds Deep: He speaks with a low, gruff voice.
- Eyes Do Not Belong There: They're all over Aqua Necklace.
- Fate Worse than Death: Deliberately inflicted on him by Josuke. Having been cornered by Jotaro and Josuke he tried to save his skin by saying that if Josuke kills him, he will become a murderer like him. Josuke answers by pummeling him and the rock behind him with Crazy Diamond before reforming the rock and fusing it to Angelo, transforming him into a living statue and eventual city landmark. Angelo proceeds to make his situation worse by not only trying to take nearby boy hostage with his power, but also insulting Josuke's hair. This prompts Josuke to beat him even more, reforming him into a grotesque statue that only vaguely resembles his face and that can't even talk like his previous state. Given Angelo's track record, that fate is very fitting. The process in the live-action film is sped up by having Angelo immediately go into the deformed rock state without mocking Josuke's hair.
- Hate Sink: Like J. Geil before him, he's a depraved serial killer and rapist who is devoid of any redeeming qualities. The brutal way he kills his victims makes him all the more repulsive, even more so than Kira. This makes his ultimate fate all the more satisfying.
- Human Architecture Horror: He ends up at the receiving end of this when Josuke fuses him with a boulder.
- If You Kill Him, You Will Be Just Like Him: Angelo himself actually tries to invoke this against Josuke and Jotaro, arguing that they have no right to kill him for his crimes. He tells Josuke in particular that if he does, he'll end up just as wretched as him. Naturally, it fails miserably, especially since Josuke had no intention of killing him at all.
- Ironic Nickname: Angelo is the Italian word for "Angel", yet Anjuro is a depraved Serial Killer and Rapist, and is one of the most evil characters in the entire series.
- Jerkass: Angelo is cruel, depraved, and petty. He revels in hurting others and toying with them all while he lines up the killing blow.
- Kids Are Cruel: He committed his very first rape and murder at the age of twelve.
- Kill It with Water: His water-based stand allows him rip people apart from the inside.
- Knight of Cerebus: Played with, in that while he's the Starter Villain, he's probably among the darker villains this Part has to offer. Once he's out of the picture, the rest of the Part is more light-hearted and comedic in comparison, at least up until Kira.
- Laser-Guided Karma: His ultimate fate, after all the horrible crimes he did, was totally well-deserved.
- Making a Splash: Aqua Necklace's power is a lot like N'Doul's Geb. The main difference is that while Aqua Necklace can't control as much fluid as Geb could at a time, it's a lot more precise, and can even control water vapor.
- Phrase Catcher: Yo, Angelo.
- Rape Is a Special Kind of Evil: Angelo is also a pervert, guilty of raping at least one woman, three young boys and planning to rape Tomoko Higashikata.
- Serial Killer: A very depraved one; his background is that he kills little boys and rapes them. Notably, one of his worst acts is nailing one unlucky victim's body parts to a wall.
- The Sociopath: Arguably even worse than Kira. While Kira does have a twisted affection for his victim's hands, and even grows to care for Shinobu, Angelo cares for nothing but himself.
- Stalker Without a Crush: He obsessively stalks Josuke for several days, just because the kid stopped his puppet's robbery. Having a Stand like him might have something to do with it though.
- Starter Villain: The early antagonist of Josuke. Jotaro's interest and build up of his character makes him seem like a Disc-One Final Boss, but it turns out he was a Psycho for Hire for Keicho.
- The Man They Couldn't Hang: He survives his hanging and leaves prison, probably thanks to his Stand.
- Token Motivational Nemesis: He kills Josuke's grandfather, who happened to be the same officer that arrested him years ago. This convinces Josuke to take an active stand against villainous , er, Stand users in Morioh.
- Too Dumb to Live: What does he say once he's cornered by the guy whose grandfather he recently murdered? "I killed your grandpa, but you have no right to judge me!" Real smooth, Angie...
- Villains Want Mercy: When cornered by Josuke and Jotaro he tries to convince them that they don't have the right to kill him despite him both murdering Josuke's grandfather and being an escaped Death Row inmate, even invoking If You Kill Him, You Will Be Just Like Him. Unfortunately for him, Josuke isn't planning on killing him.
- Weak, but Skilled: Aqua Necklace is a pretty basic Stand. But even then, Jotaro was impressed by the unique methods Angelo utilized with it (i.e., vaporizing his water based stand through the air by boiling water).
- Would Hurt a Child: He raped two boys and killed the third boy while he was held hostage. While trapped in a boulder, he tries to throttle a nearby child to death if Josuke doesn't free him. Unfortunately, that only makes him even more pissed.
Keicho Nijimura (Stand: Bad Company)
Voiced by: Tomoyuki Shimura (TV anime, JP), Jason Marnocha (TV anime, EN)
Played by: Masaki Okada (live-action movie)
Brother of Okuyasu Nijimura and wielder of the Stand Bad Company, an army of miniature soldiers, toy-sized helicopters, and tanks who deal a lot of damage.
His Stand is named after the band Bad Company.
- Abusive Parents: Like Okuyasu, their father used to abuse them after the death of their mother.
- Aloof Big Brother: Keicho tends to look down on his brother for his lack of ability to think; but despite this, he sacrifices himself to save his brother from Red Hot Chili Pepper's attack.
- Asshole Victim: After Red Hot Chili Pepper kills him, Okuyasu is angry, but admits Keicho probably had it coming.
- Arc Villain: He is main villain of the Nijimura Bros arc
- Big Bad: As the first live-action movie only adapts up to the end , he serves as this for it by default. Arguably this from beyond the grave for the first half of part 4, having made all but one of the Stand users seen in the early parts of the story. The only reason he may not be is that he averts the Sorting Algorithm of Evil by being faced well before any of the small fry he made.
- Big Brother Bully: Puts Okuyasu down a lot, like his father used to. To the point where it's unclear whether Okuyasu is really as dumb as he says he is, or if he's belittling himself out of habit, because he's so used to his father and brother doing it.
- Big Brother Instinct: Deconstructed. As a child, Keicho was very protective of Okuyasu and defended the latter from both bullies and their own father. As they grew up, Okuyasu became so reliant on his older brother that he developed the profound inability to make decisions on his own. It's implied that Keicho eventually grew to become a Big Brother Bully who constantly belittles Okuyasu's low intelligence as mentioned above, though it is unclear whether Keicho's telling the truth, or Okuyasu was conditioned to belittle himself out of habit by enduring the same treatment from his own father and brother.
- Didn't Think This Through: He uses his Stand Arrows on various people in the hopes that 1)they'll survive, 2)they'll get a power that he can use and 3)they'll be willing to help him despite not having any reason to. One of them ends up killing him.
- Disc-One Final Boss: The Man Behind the Man for Angelo.
- Dies Differently in Adaptation: Fatally electrocuted by Red Hot Chili Pepper in the manga; blown to smithereens by Sheer Heart Attack in the live-action movie.
- Dropped a Bridge on Him: Keicho was actually doing pretty well even after Josuke defeated him. Then Red Hot Chili Pepper drags him and his Arrow through a power line. This happens to leave the carried things intact, but still kills living things in the process.
- Dub Name Change: To "Worse Company" to avoid copyright issues.
- Elite Mook: Within Bad Company's ranks, the Green Berets are basically the same thing as the rank-and-file soldiers, but they also carry ropes to climb or rappel with.
- Even Evil Has Loved Ones: Less evil than typical villains in the series though. And he seems like he wants to kill his hideously-mutated father out of compassion (though it could just be disgust instead).
- Evil Sounds Deep: Keicho has a pretty deep voice.
- Foolish Sibling, Responsible Sibling: Compared to his brother Okuyasu, Keicho is more rational and calm. That said, his poorly thought-out attempt to Mercy Kill his father results in several people dying and several more gaining Stand powers, one of whom is a Serial Killer and another of whom kills Keicho and steals the bow and arrow, so this trope is zig-zagged.
- Greater-Scope Villain: For the entire first half of Part 4. Aside from two random rats, he was the one that gave Stands to much of Morioh in pursuit of his goals. Even Akira Otoishi was given a Stand because of him.
- The Heavy: While he isn't the main Big Bad of Part 4, he's the one who ends up creating its plot by shooting people all over Morioh with the Bow and Arrow thus giving them their stands one of which is Angelo whom murdered Josuke's grandfather thus getting him involved.
- Heroic Sacrifice: Spares Okuyasu a brutal death at the hands of Red Hot Chili Pepper in a similar fashion to Avdol shoving Polnareff and Iggy off from Cream's path, even if he was a little bit of a dick about it.
- Hollywood Genetics: He has blonde hair, even though the rest of his family are dark-haired.
- Jerkass: His "survival of the fittest" mentality makes him charmless and rude, speaking derisively even to his own brother.
- Karmic Death: In his pursuit of creating a Stand user to kill his father, he is killed by one of the people he turned into a Stand user in the first place. Even his brother Okuyasu knew he had it coming.
- Lack of Empathy: He feels no remorse for injuring people with the Bow and Arrow or the consequences randomly giving people Stands could have, such as with Angelo.
- Landmine Goes Click: Bad Company can deploy these. Their explosions are still roughly proportional to their small size, but are still perfectly capable of incapacitating a target; combined with their tiny size making them nigh-impossible to spot, they're surprisingly useful.
- Lilliputian Warriors: His Stand, Bad Company, takes the form of tiny, yet deadly, soldiers, complete with tanks and helicopters.
- Mercy Kill: His grand plan is to create a Stand user capable of killing his mutated father. The man's current state genuinely disturbs Keicho and be it out of compassion or disgust, he feels that killing the man would be an end to the pitiable affair.
- The Minion Master: His Stand, Bad Company, is a battalion of toy-sized army men. All of their projectiles do very real damage. And his army includes tanks and helicopters...
- Moral Event Horizon: Invoked. Believes he crossed it a long time ago, which is why he refuses to make a HeelFace Turn.
- More Dakka: The logical conclusion when he gets a whole bunch of soldiers and helicopters firing all at once.
- Multiple Gunshot Death: Whenever a squad of Bad Company opens fire, the individual bullets create deep, but small wounds where they hit. They compensate for this weakness by firing en masse; if the whole corp opens fire on one target, their victim can be easily riddled with holes from tip to toe.
- Not a Game: He uses this phrase when scolding Okuyasu for not mastering his Stand ability to the fullest potential.Keicho: This isn't a game, Okuyasu! Just thinking of the terrific power of your Stand- The Hand- is enough to make even me quake, so use it properly!
- Not Too Dead to Save the Day: It's implied by Okuyasu, who was previously hit by an air bomb, that his spirit may have saved his life by having him decide where he wanted to go: If he really wanted to be with him or go back to Morioh. Okuyasu decided to go back and ended up saving Josuke in the nick of time.
- Numerical Theme Naming: The "cho" in Keicho's name is the Japanese word for the number 1,000,000,000,000, with his brother's name featuring 100,000,000 and his father (in the movie) featuring 10,000.
- Redemption Equals Death: Whilst his redemption is debated in universe, Keicho spends his last moments faltering on his brutal ideology after being reasoned with by Josuke, and he performs a Heroic Sacrifice to save his brother. His cameo in the anime's third opening adds to this as he's alongside Shigechi, Reimi, Arnold, and Dr. Aya, all of whom are heroic characters who've been killed.
- Required Secondary Powers: Averted in that Keicho is not immune to being hurt by the ordinance wielded by Bad Company, which is why he makes a point of always being behind or otherwise out of the firing line when they're unloading on a target. Josuke takes advantage of this to reform two destroyed missiles and send them flying right at him when he's too distracted thinking he's got Josuke dead to rights encircled by Bad Company.
- Reused Character Design: His hairstyle is vaguely reminiscent of Polnareff's.
- The Social Darwinist: He states that people who don't grow don't deserve to live.
- Synchronization: Notable for its partial aversion of the long-time Stand rule that harming a Stand will harm the user. In Keicho's case, he only cares about the destruction of a few soldiers because it temporarily screwed up his army's formation.
- Stealth Pun: His Stand's name was changed to Worse Company in the subbed version of the anime, which means that it went From Bad to Worse.
- Stupid Evil: His killings of numerous Morioh citizens with the Stand Arrow in search of a worthy Stand User is revealed to be this, as it is revealed the Arrow itself can verify which of them can survive and gain a Stand, and ignores those who can't.
- Super OCD: He complains that Josuke made the ranks of Bad Company uneven, instead of lamenting the loss of power in his Stand. Whenever Bad Company shoots, he always makes them shoot in a grid pattern, each bullet spaced a precisely equal distance from its neighbors.
- Tough Love: Becomes a lot harsher on his brother in their later years. It's implied he only did so because Okuyasu had started becoming too reliant on Keicho to protect him.
- Used to Be a Sweet Kid: The flashbacks to when Keicho was young show him as being much more compassionate and adorable. He reacts angrily toward his father's abuse of Okuyasu, and was a lot more protective of him than in the present.
- Vague Age: As with a number of characters, especially in Part 4, Keicho's age is hard to pin down. In the manga Angelo even lampshades it noting that it was hard to tell if he was a teen or an adult especially with the fact that he was wearing a school uniform. His age is listed as 18.
Akira Otoishi (Stand: Red Hot Chili Pepper)
Voiced by: Showtaro Morikubo (TV anime JP, All-Star Battle, Eyes of Heaven), Andrew Russell (TV anime English)
A rock guitarist who wants to chase Jotaro out of Morioh and later tries to kill Joseph as he fears that Joseph's Hermit Purple might reveal his identity. He wields the Stand Red Hot Chili Pepper, who can travel through electrical currents and become stronger by absorbing electricity.
- Adapted Out: Does not appear in the live-action movie, instead it was Kira's Sheer Heart Attack that kills Keicho.
- Badass Armfold: Red Hot Chilli Pepper tends to do this when he thinks he's got the upper hand in a fight and decides to be smug.
- Badass Boast: Said he could beat Josuke with his pinky finger. Josuke's response? Break his pinky finger.
- Big Bad Wannabe: He is legitimately a step up in threat level from the other Stand users faced in early part 4, and the search for him is the overarching plot of the first third of part 4, but in the end he's not much of a threat at all. He didn't create any of the Stand users faced before him, only choosing to shoot two rats before his capture, stealing a bunch in the process. Part 4's Reverse Cerebus Syndrome is only driven home further when he emerges during his battle in all his silliness.
- Breakout Villain: A minor villain in the series who made it into Jojos Bizarre Adventure All Star Battle and Jojos Bizarre Adventure Eyes Of Heaven as a playable character.
- Call-Back: His Stand is one to Esidisi, one of the Pillar Men who utilizes red hot blood as his weapon. Red Hot Chili Pepper uses electrical currents to travel and attack. Doubly so when remembering that Esidisi is named after the band AC/DC, while Akira's cuff links feature the letters AC and DC on them.
- Confess to a Lesser Crime: He gets 3 years for burglary of five million dollars worth of goods, after he murdered Keicho and attempted to murder Joseph. Granted, Keicho wasn't a very good guy either and nobody can actually reveal the details of Keicho's murder without having to explain the complicated nature of Stands. Akira prefers the jailtime anyways, as he's absolutely terrified of what Jotaro and Okuyasu would do if they caught him again.
- Deliberate Injury Gambit: This is how he ends up defeating Okuyasu. After Okuyasu destroys the motorcycle that kept Red Hot Chili Pepper powered and stranded him from all other electrical ports, Chili Pepper deliberately goads him with a reverse Wounded Gazelle Gambit by implying that he's got an ace up his sleeve. He gets Okuyasu to use The Hand on him, deliberately tanking a hit so that an underground electrical cable could be pierced and he could recharge back to full health and escape.
- Determinator: Not only did he bend back his broken pinkie after Josuke broke it through sheer willpower, but when Red Hot Chili Pepper got almost destroyed upon falling into water, he lived through all that even if he seemed like he Died Standing Up.
- Disc-One Final Boss: In the first third of Part 4, the story focuses on trying to get revenge on Red Hot Chili Pepper for killing Okuyasu's older brother. But he turns out to be far too dim-witted and easily beaten for a JoJo Big Bad.
- Dub Name Change: The original manga and anime occasionally shorten his Stand's name to just "Chili Pepper", presumably because of how long it is. The English translations just use the shortened name every single time.
- Establishing Character Moment: While not his first appearance, his visit to Josuke in his home counts as one. The scene establishes the Paranoia Fuel behind Red Hot Chili Pepper's powers as he has been spying on the main cast without them knowing. He exposits a bit on his motives, and goads Josuke into hitting him. His overconfidence is established, but more importantly, so is his fallibility as Josuke gives him a sound beating.
- Everything's Better with Dinosaurs: Red Hot Chili Pepper resembles a Pachycephalosaurus, with its prominent head dome.
- Game-Breaking Injury: Akira himself makes it out of his fight okay, but Red Hot Chili Pepper is permanently maimed to such a degree that Jotaro no longer sees him as much of a threat.
- Glory Seeker: He is dedicated to his craft as a musician; wishing also for recognition or fame as a Rock star. After he is released from prison, he continues to pursue this goal.
- Good Scars, Evil Scars: Has a lightning-bolt-shaped scar crosses the left of his face vertically, from his forehead over his left eye to his jaw.
- It's All About Me: Akira is highly self-centered.
- Jerkass: Smug and full of himself, not to mention how he murders Keicho to steal the Stand arrow.
- The Knights Who Say "Squee!": A Stand user himself, he is a fan of Rohan Kishibe's works. In Thus Spoke Rohan Kishibe: Mutsukabezaka, he receives an autograph made of coffee in a paper sheet.
- Large Ham: A guy dressed like that is obligated to be theatrical. When Josuke dislocates his pinkie, Akira forces it back through sheer will, and channels his pain and anguish into a shredding guitar solo.
- Logical Weakness: Being an electric being, Chili Pepper possesses the familiar weaknesses.
- Played With in regards to Rubber. During his fight with Josuke, Chili Pepper is trapped within a rebuilt rubber tire and thus the insulation prevented him from using his electricity. However Chili Pepper is still a physical being with a decent amount of strength so he just punches through it, which leads to...
- Water. When he punches through that tire, the compressed air launches Red Hot Chili Pepper into the ocean, dispersing its electrical power as well as its body.
- Loophole Abuse: Red Hot Chili Pepper is technically a very long-range Stand, meaning that while it does not reflect damage back to Akira, it should not be strong enough to match a close-range power Stand like Crazy Diamond blow-for-blow. However, its ability to empower itself via electricity means that so long as it has a ready source of power nearby, it becomes a Master of All with only two clear weaknesses: water, and its user being assaulted.
- Meaningful Name: "Otoishi" means "sound rock".
- Non-Indicative Name: Red Hot Chili Pepper is yellow in color, not red.
- Personality Powers: His Stand matches his electrifying personality, It's also great at hiding in plain sight (I.E in motorcycles, televisions and powerlines) which interestingly resembles what Akira does to get on-board the Speedwagon foundation's ship at the end of his arc.
- Pint-Sized Powerhouse: Red Hot Chilli Pepper is a short and unimpressive looking Stand. But when charged up it can fight toe-to-toe with and even overpower Crazy Diamond in close combat, something that not even Killer Queen could do.
- Pummel Duel: When fully-charged on electricity, Red Hot Chili Pepper engages in an intense one with Crazy Diamond. He actually wins and punches both Stand and Josuke away and seems to have the fight in the bag. But that's when Josuke pulls out his final gambit.
- Psycho Electro: His electric Stand reflects his psychotic personality.
- Ride the Lightning: Red Hot Chili Pepper can do this to travel through electric power lines and objects. He can also do this to other people by dragging them along for the ride...and then leave them stranded in the power lines.
- Smug Super: Absolutely sure of himself. The worse part is that he can back it up.
- Shock and Awe: Red Hot Chili Pepper is capable of absorbing electricity to use as energy for a number of things, including increasing its raw strength, movement, healing its wounds, levitating, and covering itself in an electric coat. We're talking about a Stand that can manipulate the entire power grid of Morioh.
- However, this strength also limits the Stand's range, as it must remain near power to avoid depleting all of its strength.
- Super Speed: Fitting for a Stand that utilizes electricity so thoroughly, when charged up it's easily as fast as lightning itself, outspeeding The Hand's erasing strike to land a crippling counterattack and getting the better of Crazy Diamond.
- Synchronization: Downplayed. While it's unknown what happened to Akira when RHCP got his mid section scraped away, he seems fine afterwards. When Chili Pepper is defeated by being thrown into the ocean, both he and Akira are fried by the electrical discharge. However, while both survive, Chili Pepper was rather gruesomely maimed and came out missing a few limbs and had his face broken in half; Akira has none of those injuries.
- Super Power Lottery: Red Hot Chili Pepper's stats is A ranks in everything but Precision, notably having a range of kilometers while still being able to match up in power with close range Stands and being able to charge itself up or move undetected through electrical wires and batteries. Had Akira aspired to be anything more than a rock star with petty thievery on the side, he could have been one of the most powerful Stand Users in the series.
- Teleporters and Transporters: Red Hot Chili Pepper can pass through electrical systems, including power wires or batteries, at light speed.
- Underestimating Badassery: While Akira fears Jotaro's power, he underestimated both Okuyasu and Josuke. Okuyasu nearly defeated him and Red Hot Chili Pepper escaped only thanks to his manipulation and Okuyasu's impulsiveness. When Akira personally showed up to kill Joseph, he believed Josuke to be an easy match, underestimating the youth, which led him to his defeat.
- Weaponized Teleportation: Being dragged through a high-voltage line by Red Hot Chili Pepper is pretty lethal.
- Would Harm a Senior: He tries to murder Joseph, who by this point is a frail and senile elderly man.
- You Gotta Have Blue Hair: Akira has long purple hair.
"Bug-Eaten" and an Unnamed Rat (Stand: Ratt)
Two rats who were pierced with the Stand arrow, granting them both the Stand Ratt. Jotaro nicknames one of them "Bug-eaten" due to one of its ears having a large chunk missing. Ratt resembles a small turret-like robot and fires toxic barbs, which melt anything they hit into a sort of blood gelatin for the rats to eat later.
Their Stand is named after the rock band Ratt.
- Amplified Animal Aptitude: Like all Stand using animals in Jojo's, their new powers come with enhanced intelligence. The pair become skilled tacticians, and Bug-Eaten is able to lead and trap the heroes before pinning them down under sniper fire. Bug-Eaten even figures out how to get around Star Platinum's time stop.
- Bait-and-Switch Boss: The unnamed rat is dealt with relatively easily, while Bug-Eaten puts up much more of a fight, and is only defeated near the end of the episode.
- Body Horror: Ratt can fire off barbed bullets, which will melt anything upon impact for it to be formed like gelatin or clay. This is very painful and would often lead to the death of one who falls victim to the bullets.
- Cold Sniper: Despite Ratt being a turret, Bug-Eaten uses it for sniping instead of static defense.
- Ear Notch: Jotaro gave the second rat the name "Bug-Eaten" was because the notch in his ear reminded him of a leaf partly eaten by insects.
- Exactly What I Aimed At: Bug-Eaten is on both the giving and receiving end:
- When Jotaro begins using Star Platinum to dodge Ratt's fire, Bug-Eaten notices and starts leading his shots, at one point aiming at a rock so that the ricochet hits Jotaro after he's already used the time stop and thus isn't prepared to react.
- Later, Josuke uses one of his bullets to hit the rock Bug-Eaten was hiding behind to draw him out of cover, setting him up for a kill-shot.
- Glass Cannon: Their Stands are deadly and precise, even giving someone like Jotaro a lot of trouble. But they're still rats, so one shot is all that's needed to take them out. Even when Josuke shoots the first one non-fatally, the rat bleeds out shortly afterwards.
- Hoist by His Own Petard: A very minor example, but Bug-Eaten uses one of the rat traps Josuke planted earlier against him to expose him for a neck shot.
- Hollywood Acid: Ratt's darts can cause rocks and metal to melt in seconds.
- Mundane Utility: Ratt's bullets turn whatever creatures they hit into a gelatin-like consistency, typically killing them in the process. What do Bug-Eaten and the other rat use this for? Expanding their territory and collecting food, essentially what they would be doing as normal rats, only now with freaky psychic powers.
- Nearly Normal Animal: A case of MNA. The rats are clearly smarter than your average rat, being able to use tactics and adaptation while fighting Josuke and Jotaro, but at the end of the day their instincts are still mostly what you would expect of a rat: Expanding their territory and gathering food. They dont even seem to be acting out of malice, and their desire to hunt and eat comes from their natural instinct (just in a much, MUCH more dangerous way now that they have a Stand).
- No Name Given: Jotaro made up "Bug-eaten"'s name. If it has a real one, it never gets revealed, unlike the Stand-using animals from Part Three. The other rat is never given a name at all.
- Oh, Crap!: Bug-Eaten recoils back while shrieking in a pointless attempt to evade Josuke's counter-attack after he realizes that Josuke tricked him into leaving cover with a fake miss.
- Uplifted Animal: Played With. As with all other Stand-using animals, the rats become much more intelligent and cunning when given their abilities. However, while previous animals like Iggy and Forever became more human-like in their actions and reasoning, the Rats tend to act more like animals, simply using their powers to expand territory, eat, and defend themselves.
- You Dirty Rat!: Bug-Eaten is aggressive and cunning, being on the offensive against Jotaro and Josuke and nearly killing both of them.
Yoshihiro Kira (Stand: Atom Heart Father)
Voiced by: Shigeru Chiba (TV anime JP), Steve Kramer (TV anime EN), Bin Shimada (All-Star Battle)
Yoshikage's father, who died before the events of the story. His Stand, Atom Heart Father, allows him to live on inside of photographs, and manipulate anything within what the photograph contains.
- Asshole Victim: Inadvertently gets blown up by his son. The son whose murders he helped to cover up.
- Beard of Evil: He's got a non-connecting mustache and spiked chin beard both of which are smaller sinister facial hair that helps accentuate his bombastic emotions. It's quite telling that the photos of him alive look much more docile because the beard adheres closer to his chin and the mustache is smaller and less dynamic.
- Death by Irony: In the final battle, he gets killed (definitively) by one of Killer Queen's air bombs. More specifically, during the fight, Yoshihiro flits about in secret to communicate to Kira how to direct Killer Queen's incendiary bombs. Unfortunately for him, Josuke realizes this, and so is able to bait Kira into detonating a bomb right next to Yoshihiro's photograph, causing him to cease to exist as the photograph burns up.
- Doting Parent: A villainous example; even after death, he continues to enable his son's criminal lifestyle.
- The Dragon: To his son, Yoshikage. He is extremely devoted to him and takes supporting him and his ambitions to the extreme, even going as far as to protect his son's serial killer lifestyle.
- Dub Name Change: Atom Heart Father is shortened to Heart Father in the English version of All-Star Battle, the Dub, and the Crunchyroll subs.
- Evil Counterpart: To Reimi and Joseph, even if he doesn't actually interact with either of them.
- For Reimi: Both of them being ghosts who are the driving forces for their respective sides in deciding his son's fate. Reimi brings the heroes together to help her catch him, while Yoshihiro creates Stand Users with the Arrow to attack the heroes in order to protect him.
- For Joseph: Both of them have photography-related Stands. Their sons are The Hero (Josuke) and Big Bad (Yoshikage) of the story, who likely inherited good and evil nature from them and play a lesser role in giving their respective support.
- Evil Old Folks: He has the appearance of a lightly-built, balding old man.
- Family Theme Naming: Yoshihiro and his son, Yoshikage.
- Greater-Scope Villain: For the second half of Part 4, and possibly all of it to a lesser extent. Enya and Dio, who didn't give a Bow and Arrow to just anyone, entrusted him with the one that gave himself and Yoshikage (and eventually some other characters) their Stands. Plus Yoshikage is his son, after all, and with Atom Heart Father, he could be one of the many reasons those murders stayed a secret for so long. Neither of them had to do anything in the story until the heroes took pursuit.
- Heart Is an Awesome Power: Think Atom Heart Father sounds weak? He came within inches of killing both Jotaro and Josuke. It's because any person in a photo with him in it is bound by the area that the photo covers, and whatever Yoshihiro does to the people in the image will happen to the actual people, without any way to stop it. And doing anything to the photo yourself causes that damage to happen to the people in it (such as when Josuke ripped up the photo, which resulted in both he and Jotaro being ripped like the photo and forcing him to use Crazy Diamond to repair it). The only way to defeat this is to take another photograph that makes him the only feature. And even when his Stand's main power is defeated, it still allows him an extreme amount of autonomy since he's still able to manipulate the photo itself and interact with the outside world.
- The Heavy: Nearly every Stand that was introduced after Atom Heart Father was due to Yoshihiro personally shooting their users with the Arrow. Including Kira's Bites the Dust.
- Karmic Death: Unintentionally blown up by his beloved son, who he let rampant and was trying to protect.
- Manipulative Bastard: It is not difficult for him to fool Okuyasu, making him believe that he was escaped from the photo where Jotaro, previously, had trapped him.
- Moral Myopia: He stands fast by the idea that he should support his son's desires. Even when that son, as early as his teens, had an unstoppable need to kill women and take their hands for his own. This could have something to do with how easy it is to kill someone that doesn't have special powers like they do.
- Our Ghosts Are Different: The only reason he's sticking around is because his Stand binds his soul to photographs.
- Papa Wolf: A villainous example. He will kill you horribly if you threaten Yoshikage's peace of mind.
- Pragmatic Villainy: In contrast to Keicho's method of shooting whoever he could with the Arrow to see if they could get a Stand, Yoshihiro has the Arrow guide him to people who it chooses. He's doing it to get the best results out of the Arrow's use, and as a result he's not just killing random people who didn't have the fortitude to make a Stand.
- Pushover Parents: Taken to a pretty horrific extent where he'll be an accomplice to many murders just to make his son happy.
- Reality Changing Miniature: He became bound to a photograph through his Stand after death. Now, courtesy of Atom Heart Father, he can manipulate the area depicted in whichever photo he's bound to. Whatever he does in the photo, happens in the actual place, and he can even trap anyone who's there. He came within centimeters of killing Josuke and Jotaro. All that stopped him was Jotaro taking another photograph of the photo — making sure to put only Yoshihiro in it, thus trapping Yoshihiro in an otherwise-empty picture.
- Suspiciously Similar Substitute:
Ken Oyanagi (Stand: Boy II Man)
Voiced by: Chika Sakamoto (TV Anime JP), Laila Berzins (TV Anime EN), Miho Hino (All-Star Battle)
Also called "the RockPaperScissors kid". A young admirer of Rohan Kishibe who also wants to challenge him to a RPS duel. He wields the Stand Boy II Man, who can drain the energy of another Stand user by playing a Rock Paper Scissors game and winning it.
His Stand is named after the R&B trio Boyz II Men.
- Absurdly High-Stakes Game: Boy II Man creates an insanely one-sided one with an opponent. If they lose, their Stands are forfeit. Oyanagi on the other hand risks nothing when he plays.
- Adaptation Dye-Job: Has brown hair in the manga, but the anime gives him white hair instead.
- Better to Die than Be Killed: After losing, he throws himself into the way of a truck to avoid having his powers locked by Rohan. Impressed, Rohan jumps along and the truck misses them both by chance.
- Body Horror: See that noticeable dark spot on his left cheek? That's not a mole, that's actually a hole (courtesy of Yoshihiro Kira's Arrow). It can even suck in Stands.
- Bratty Half-Pint: He's pretty petulant.
- Call-Back: To the D'Arby brothers in Stardust Crusaders. Similar to them, his Stand works when he challenges someone for a game, taking something (the soul or, in the case of Ken, the Stand) from said person if they lose.
- Creepy Child: It's bad enough that this kid stalks Rohan to challenge him to Rock Paper Scissors matches, but then it turns out those matches have Rohan's life energy at stake.
- Dub Name Change: Boy II Man is renamed BoyManMan in the English version of All-Star Battle. Interestingly enough, it's also renamed to Boys Man Man in the Crunchyroll subs.
- The Fatalist: Really obsesses over the power of luck until Rohan defeats him.
- Hypocrite: Ken calls out Rohan for using an invisible baby to fold in his fingers to turn his call of paper to rock, forgetting that he himself only won round three by considering Rohan punching him as calling rock, ignoring the fact Rohan refused to play and the fact that getting punched means the puncher would need to fold in their hand and the person getting hit will likely open their own in shock.
- Magic A Is Magic A: There are some rules to the usage of Boy II Man. It can only play 5 matches, take portions of the energy in thirds, and if it loses, he must return the energy. Perhaps its greatest weakness is that it can neither detect nor punish cheating.
- No-Sell: After gaining the right arm of Heaven's Door via Boy II Man, he is able to use it to get rid of Rohan's signature "Cannot harm Rohan Kishibe" command placed on him.
- People Puppets: Boy II Man has limited control over his opponent's Stand, allowing him to control the area corresponding to the energy he drained in the Rock Paper Scissors game, as shown when he makes Rohan punch himself after taking the right arm of Heaven's Door.
- Personality Powers: Boy II Man's ability is a manifestation of Ken's philosophy regarding adulthood. Basically: Rock-paper-scissors is not game of luck, but of willpower—it looks random, but the player with the stronger will wins every time. Rohan, as a highly successful 20 year-old, is a shining example of a "kid" becoming an "adult", and if Ken can defeat Rohan in rock-paper-scissors, it means his will is stronger and he is the greater man.
- Power Parasite: Boy II Man could drain the energy of another Stand user by playing a Rock Paper Scissors game and winning it allowing the possibility to use his power. However, as explained above, they are strict rules to how this is played.
- RockPaperScissors: Yes, Boy II Man uses that as its modus operandi. He can compel someone to play a 3-of-5 match with him. That's it... until he wins. If he ever gets to finish a match and win, he'll permanently hijack the loser's Stand.
- What Happened to the Mouse?: The only character who isn't dead or otherwise incapacitated that doesn't show up in the epilogue.
- Wound That Will Not Heal: The hole in his cheek from Yoshihiro's arrow, like actual wounds of that nature, doesn't heal naturally.
Tama (Stand: Stray Cat)
Once a normal British Blue cat, he was hit with an Arrow and found his way into the basement of the Kawajiri house, where he was accidentally killed in a scuffle with Shinobu. After Kira buried him in the garden, he was reborn as a strange, animal-like plant with the Stand Stray Cat, which allows him to compress air into "bubbles" and shoot them at deadly velocity.
Due to the ambiguous nature between Stand and user, he is mainly referred to as "Stray Cat" after his revival. Stray Cat is named after the rockabilly band the Stray Cats.
- Amplified Animal Aptitude: In terms of using its abilities it adapts very quickly to clever applications on seeming instinct, otherwise it's exactly like any other cat. It very quickly uses it powers offensively, for revenge and food. In its fight with Kira it shrewdly bypasses Killer Queen's defense with the shrapnel from cactuses it blows up. Failing that it tries to give him an embolism by sneaking a large amount of air into his veins.
- Attention Deficit... Ooh, Shiny!: Of the sort that afflicts most cats — Kira is able to distract him by giving him a golf ball to play with.
- Adaptation Dye-Job: Zig-Zagged. In the manga, his petals are bright pink but the anime changes the color of to a blue-grey color that more closely matches its original fur color as a cat. This is only for his initial form though, when he grows into his second form the petals change back to the manga's pink keeping his appearance similar to Killer Queen.
- Back for the Finale: The anime adaptation adds an epilogue scene that shows what the people of Morioh are doing now that Kira's been defeated. It's seen at Tonio's restaurant with Okuyasu and his dad, and seems much happier with its life now that it isn't being used as Killer Queen's striker.
- Barrier Warrior: Tama can use its air bubbles for defense as well as offense.
- Berserk Button: Don't try to take away Tama's sunlight. Also, don't be Shinobu Kawajiri (she was responsible for the cat dying).
- Blow You Away: Tama's Stand, Stray Cat, has the ability to manipulate air, capable of creating air bubbles strong enough to hold a person against a wall or enter their veins, blocking blood passage. This is powered by its photosynthesis; the stronger the light, the stronger the control Stray Cat has over the air.
- Bubble Gun: Tama's ability allows him to make bubbles.
- Cats Are Magic: Though it could be considered a subversion, since at this point in the series, there'd already been a magical orangutan, a magical dog, a magical falcon, and two magical rats, but what is magical about it is that it's a plant with a cat's mind that can manipulate the air around it.
- Cats Are Mean: Tama is stubborn, sticking to its territory in the cellar when Shinobu Kawajiri attempts to chase it out. After it is killed, it shows a desire for revenge, and attacks Shinobu when it sees her in the garden. Subverted in the end, where the kindness of Okuyasu and his family made Tama mellow down and settle comfortably in the life of being a house cat.
- Cool Pet: Tama... is a flower. With a cat's brain. If you don't get why that's cool, you're reading the wrong manga. At first, Tama was Kira's ally. After Okuyasu gets Tama away from Kira and tames it during the final battle, it is taken in by Okuyasu's dad, it's officially part of the Nijimura household.
- Creepy Cute: As a flower, Tama looks a tad disturbing due to its fleshy petals and large eyes seemingly connected to thin stalks, but when it plays with the golf balls Kira gives it or takes a nap in its flower pot it looks downright adorable. It's even better in the anime where it gets a small Cat Smile when it starts warming up to Kira.
- Does This Remind You of Anything?: Tama/Stray Cat being used by Kira to provide Killer Queen some air bubbles is very similar to an animal being used and trained by an abusive owner to only attack people. Once Okuyasu gets Tama away from Kira and Okuyasu's dad adopts Tama as a pet, it no longer has the urge to attack people and behaves quite amicably.
- Dub Name Change: "Stray" becomes "Feral" for the English version of All-Star Battle. Interestingly it is still called Stray Cat in the Crunchyroll subs despite most of the name changes sticking from ASB.
- Equippable Ally: After the effects of Bites the Dust are deactivated, Kira puts Stray Cat in the gap in Killer Queen's stomach and combines its abilities with his Stand's in order to create bombs from the balls of air manipulated by Stray Cat.
- Eyes Do Not Belong There: Tama's eyes are on the inside of his petals.
- Furry Reminder: Despite being a plant-cat hybrid with a Stand, Tama's still a cat at heart. When Kira throws it a golf ball, Tama immediately diverts its attention to the object moving in front of it and starts playing with the golf ball like a real cat. It also likes to doze off and sleep in sunlight.
- Happily Adopted: After the final battle with Kira Stray Cat gets adopted by Okuyasu and his dad, and the creature seems much happier with them than it was as Killer Queen's ringer. The epilogue of the anime even shows it joining Okuyasu and his dad for lunch at Tonio's restaurant, and having no violent urges or need to shoot its air bubbles despite being in a bright sunlit café.
- Having a Blast: His bubbles become explosive after being taken and used to attack by Kira.
- Heart Is an Awesome Power: It can manipulate air and make bubbles. Doesn't sound like much, but when those bubbles pop, they put out a lot of force. And then it almost killed Kira by forcing an air bubble into his veins. Oh, and Kira can turn those bubbles into bombs...
- HeelFace Turn: The epilogue of Part 4 states that Okuyasu's dad adopted Tama as a pet, which vastly improved Tama's life now that he's not being used as an attack animal anymore. He starts acting like a normal house cat, and doesn't have the urge to air bubble anyone.
- Killer Rabbit: He's a flower with the mind of a cat. He almost killed Kira.
- Not-So-Harmless Villain: He's just a plant with a cat's mind! How dangerous could he be? Answer: Very. And that's before Kira realises that he can use him to make air bombs...
- Only Known by Their Nickname: The cat is never given a proper name outside of the Stand Encyclopedia that came with the 25th anniversary "JOJOVELLER" collection, which lists Stray Cat's name as "Tama" (along with the word "Former" due to it dying before manifesting its Stand).
- Planimal: After being buried in their garden, its dormant Stand ability brings it back to life as a cat-like plant named Stray Cat. Its photosynthesis seems to go largely to powering its abilities, as it still eats, and its roots (which have paw-shaped ends) are used for excretion instead of taking in nutrients.
- The Power of Hate: How Tama first discovered his Stand power, thanks to his hatred toward Shinobu that accidentally killed him when he was a normal cat.
- Reincarnation: Originally a cat hit with an Arrow; Tama died and got reborn with a new Stand, Stray Cat, attached to him becoming a living cat-plant.
- When Trees Attack: Tama's a plant-cat hybrid with seemingly harmless yet devastating air attacks.
- Wound That Will Not Heal: Similarly to Ken Oyanagi, it had an open hole in its neck from being shot by the Arrow when it was still a cat. It disappears when it comes back to life as a plant.
Toyohiro Kanedaichi (Stand: Super Fly)
Voiced by: Koichi Tochika (TV anime JP), Sean Chiplock (TV anime EN)
A hermit living a lonesome life in an old, retired telephone tower. His Stand is Super Fly, a completely autonomous Stand bound to the tower, which reflects all damage done to it in the form of blasts of energy and traps the last person to leave it within its boundaries.
- And I Must Scream: Trapped inside a transmission tower for the rest of his life, unless he can get someone else to take his place. Eventually he becomes okay with his fate, though. Attempting to leave the tower may be even more so, as doing so causes Superfly to turn its captive into a part of the tower itself, a humanoid mass of metal.
- Anti-Villain: All he wants is to escape from Superfly. Even as he plans to leave Josuke trapped in it, he offers up some advice on how to get out, like getting his friends to help him swap places with a criminal. He doesn't actually try to kill Josuke until he gets too stubborn in trying to force him back in. In the end, he reveals that he's been stuck for so long that part of him didn't actually want to leave, and he eventually agrees to stay behind.
- Attack Reflector: Any damage given to Superfly gets sent back to whoever struck it. He weaponizes this by knowing how to attack the tower and accurately aim the reflected shot.
- Back for the Finale: In the manga he departs from the story after his arc, but in the anime he shows up in the final episode sharing a meal with Mikitaka.
- Badass Normal: He's very athletic and well built due to having lived in the Tower for so long and he's quite able to swing around and avoid Josuke with ease. He can't use his Stand against the heroes because of its autonomous nature, but after years of living in it, he's found ways to make it work for him.
- Blessed with Suck: While it isn't immediately lethal, Super Fly is directly detrimental to him (or, to anyone who gets stuck in it) and stops him from leaving its confines, but he's learned how to work around its properties.
- Call-Back: To Gray Fly, and the old man that uses an insect Stand named "Tower of Gray". Compared to Kanedaichi who uses a tower Stand named after an insect.
- Charles Atlas Superpower: He's rather athletic because of the physical demands of his unusual living conditions.
- Counter-Attack: Superfly can absorb the power of any attacks done into the pylon and redirect the energy back. When Josuke and Okyuasu tried to pummel one of the supports down, Superfly responded by unleashing flurry of punches where they attacked. Toyohiro can also take advantage of this by scratching at the steel beams to create Pinball Projectiles that bounce around the structure like billiard balls.
- Defeat Equals Friendship: Once Josuke hits the final blow, he resigns to stay within the tower and allows the protagonists to leave, even giving them a warning on their next opponent. He ends up becoming a landmark in Morioh and enjoys a small amount of fame with curious tourists, and in the anime's epilogue, he's shown to host Mikitaka in the tower on friendlier terms.
- The Faceless: As it's revealed that his "face" was a mask and it's never shown what he looks like under it, he qualifies for this trope.
- Genius Loci: His Stand is bound to the telephone tower he lives in. While it's great that it attacks autonomously, it also really hates when people try to leave it, user included.
- Good Eyes, Evil Eyes: He has fairly normal-looking eyes when he first appears as a seemingly neutral person. Those eyes suddenly gain black sclera during his fight with Josuke. After the fight, when he decides to give Josuke advice on Yoshihiro, those sclera are white again.
- Gonk: Once it's revealed that he wears a mask, it starts looking more and more like this as the fight goes on, though what he actually looks like under the mask is never revealed.
- Improbable Aiming Skills: Able to bounce all his shots off the girders of the tower he's in and hit his target multiple times in quick succession, and in ways that attack from both sides. He's also using a knife hidden in his callouses to scratch the tower, which would seemingly imply a lack of precision.
- Latex Perfection: His "face" is actually a mask, but doesn't look like it is until later in his arc.
- Non-Indicative Name: Super Fly takes the form of a giant transmission tower, rather than a bug of some sort like its name would imply.
- No Name Given: According to him, Toyohiro Kanedaichi is not his real name. If that's true, his real name was never revealed.
- Non-Residential Residence: Lives inside a telephone tower, of course. It's surprisingly self-sustaining; for food, he can gather vegetables and meat from small animals using traps in the bushes surrounding Super Fly, cook them using a hybridized frying pan and fishing rod, and collect rainwater purified through a filter. He even has a set of books, a a single sofa, and a solar-powered television on the upper levels of the tower.
- Not Good with People: The reason he was living in Superfly to begin with was because he's this. The only reason he tried to escape at all was because Yoshihiro, likely falsely, promised him he'd take care of him if he trapped one of Josuke's group in Superfly.
- People Zoo: A variation; after the events of his arc, Toyohiro is considered "a landmark of Morioh". He's regarded like a local attraction, and tourists visit him and take pictures with him in exchange for salt, sweets, and spices, which he can't obtain from the tower's surroundings.
- Pinball Projectile: He manipulates Superfly's damage reflection to create bouncing beams of energy by scratching at its supports.
- The Tower: He was actually trapped within his transmission tower by his own Stand Superfly.
Terunosuke Miyamoto (Stand: Enigma)
Voiced by: Kengo Kawanishi (TV anime JP), Alan Lee (TV anime EN), Makoto Naruse (All-Star Battle)
A man obsessed with fear. Wields the Stand Enigma, which allows Miyamoto to turn targets into pieces of paper if he can successfully identify their fear-based Character Tics.
His Stand is named after the German New Age project Enigma.
- Ain't Too Proud to Beg: After he is defeated, Miyamoto tries to make Josuke let him go on the grounds that he just likes watching people in fear and he only just got his Stand so he was cocky. He even tries apologising to get out of a beating. Unfortunately for him, after all the stunts he pulled during the arc, Josuke is in no mood to comply.
- And I Must Scream: Josuke binds him into a spiral-bound book in order to put an end to Enigma's threat. However, a legend develops that the Miyamoto book can be heard whispering, so it might not completely apply. Like Angelo, he now lives inside an object forever!
- Dark-Skinned Blonde: He has skin of medium tone, light eyes and light hair in a criss-cross on his crown.
- Dirty Coward: For all his talk of fear, Miyamoto is shown to be quite the coward himself. As Josuke notes during their fight the only reason Miyamoto is confident enough to fight him is because he is holding Koichi hostage. At the end of his arc after Yuya Fungami manages to free Josuke and Koichi from Enigma Miyamoto initially threatens to tear the piece of paper containing Yuya in half and when that doesn't work begs Josuke to let him go on the grounds that he just let his Stand get to his head. Josuke doesn't oblige.
- Disproportionate Retribution: He really isn't a nice man at all given that he's a kidnapper and attempted murderer, but did he really deserve to be trapped forever as a fully conscious sapient immortal book that will always be alone? Especially since several characters who have done similar or even worse things than him had gotten away with just a beating.
- Dissonant Serenity: When talking to Tomoko, he sounds eerily calm while demonstrating his powers and explaining reflexive reactions to fear, all to play up his creepiness and force her to give away her nervous habit. Once Enigma activates, he drops the serenity and loudly gloats that his victim is helpless.
- Dub Name Change: Enigma is changed to Misterioso in official English translations. Musical Theme Naming is still in effect—"Misterioso" is a composition by Thelonious Monk.
- Fate Worse than Death: Using his own Stand ability against him, Josuke terrifies Terunosuke and then uses Crazy Diamond to pummel him until he becomes a book. He is then donated to the Morioh Library. If one asks for "Enigma" to the staff, they'll bring the book to you, but no one can take it home. If one reads the book, they might hear Terunosuke's voice from within.
- Hammerspace: Enigma can give paper this property.
- I Have Your Wife: Miyamoto kidnaps both Koichi and Tomoko to use as hostages in his battle with Josuke. These actions are what truly infuriate Josuke and why he gives Miyamoto his Fate Worse than Death.
- I Know What You Fear: Enigma can trap a living person inside paper too, as long as Terunosuke knows what Character Tics to look for in each person. As it turns out, he's not immune to his own power.
- Jerkass: Deeply enjoys scaring people, and does so far beyond what he needs to utilize Enigma.
- Laser-Guided Karma: It hits him like a freight train; he relished turning people into paper when they show fear. Josuke turns him into a book.
- Loophole Abuse: It's implied from the taxi he releases that he could trap people without needing their tell if he's trapping an object with a person inside it.
- Phantom Zone Picture: He can turn anything or anyone who shows their fear into a piece of paper, forever trapping them unless the paper is unfolded.
- Psycho for Hire: Notable because most of the time Yoshihiro just shoots a person with the Arrow and lets them loose on Morioh, but he went out of his way to recruit Terunosuke and Toyohiro. Of the pair, Terunosuke makes it clear that he enjoys his new work of scaring people into paper prisons and isn't doing it out of any necessity.
- Suspiciously Similar Substitute: He has a similar hairstyle and smarmy attitude to Steely Dan from Stardust Crusaders.
- Weaksauce Weakness: Unlike most Stand Users whose Stands are non-integrated, Teronosuke is not immune to the effects of his own Stand. Even more unfortunately, despite his big talk, he isn't a particularly fearless person either.
Masazo Kinoto (Stand: Cheap Trick)
Voiced by: Makoto Ishii (TV anime JP) Stefan Martello (TV anime EN)
A quiet and timid, yet greedy architect. He unwillingly holds Cheap Trick, an independent Stand who whispers in the wielder's ear that anyone who sees his back will die; the person who sees the back of Cheap Trick's user becomes the new host to Cheap Trick.
Cheap Trick is named after the band of the same name.
- Absurd Phobia: The thought of people looking at his back scares him. Given that he's Cheap Trick's initial carrier, he has all the reason to do so even if he's unaware of Cheap Trick's presence, but it's implied he was like that even before he gained a Stand.
- Adaptation Dye-Job: Subverted. Early images from his cameo and the "Great Days" opening seem to give him brown hair, but his proper appearance has him retaining the same orange patch he has in the manga.
- Anti-Villain: Even when he becomes one of Yoshihiro Kira's minions through the Arrow, Masazo in general is rather quiet and socially awkward, and isn't actively hostile compared to other antagonists in Part 4; the closest he strays to being malicious is wanting to charge Rohan extra, knowing how much he was worth. Unfortunately, it's because of that passive nature that Masazo is unable to control his Stand.
- Body Horror: Anyone who's had this Stand removed will have their back opened and die, as well as shrink down to a shriveled corpse the size of the palm of your hand.
- Call-Back: To Anubis in part 3, as Cheap Trick cannot be controlled by its user and can find a new user to possess. Additionally, as with Anubis, the Stand itself is the arc villain while the original user is a pawn.
- Death by Irony: Cheap Trick kills its owners by waiting for someone to look at their backs and will do everything in its power to force such a scenario. Cheap Trick is defeated when Rohan exploits the fact that anyone who looks back while in Reimi's alley will be Dragged Off to Hell and positions himself and Koichi so that Cheap Trick has to look backwards and suffer this fate.
- Dragged Off to Hell: Rohan specifically does this as a command for Cheap Trick.
- Dub Name Change: Cheap Trick is renamed to Cheap Trap.
- Enemy Within: Kinoto wasn't strong-willed enough to control a Stand, so it manifested as an externalization of his own fears and went along with Yoshihiro Kira's plan to kill Rohan, knowing that it would kill its own User.
- Gonk: Kinoto ends up looking very odd due to the way his face is emphasized. He's got a small X of hair on the crown of his head, leaving the sides bald, his lips are large and distinctly colored, and his eyelashes stand out quite a bit to make his eyes pop out. This is coupled by some of the weird faces he makes, like when he's drooling when he gets caught in the floor.
- Nice Job Fixing It, Villain!: Overlaps with Yoshihiro Kira for creating Cheap Trick. Cheap Trick tried to get Rohan to burn the photos he had of Hayato following people with a Camcorder, confirming that Kira was one of the crowd people.
- Omniglot: Cheap Trick's voice can be heard and understood by anyone, even animals; it uses this talent to insult anyone it can in order to get people (or dogs and cats) to attack its host.
- Synchronization: A rather interesting case in this series, as it essentially attaches and becomes a separate Stand to whoever sees the back of the previous person. When it's on the back of another person it synchronizes to them as their own Stand would, as seen when Rohan tries to open its face with Heaven's Door, he gets his own face torn for the trouble. Attempts by Rohan to tear it off his back cause his back to be injured. Rohan has to force a scenario where only Cheap Trick will be affected in order to defeat it and save himself.
- Torment by Annoyance: Cheap Trick outright weaponizes this trope by constantly annoying and belittling its host because it has nothing else. Its only attack works when someone looks at the host's back, and its stats are the lowest possible ranking in every category... except for its A-Rank Persistence. Cheap Trick's second plan for killing Rohan is to drive him insane to the point he'd do anything to stop listening to it.
- Verbal Tic: Cheap Trick tends to repeat or reaffirm everything it says. ("Burn the photos! Do it!")
- Also, in English, it tends to finish its statements with Yes? In Japanese, it ends them with -ne, an ending which means you expect the other person to agree with you, similar to the English isnt it? or dont you?, which is fitting for its wheedling, coercive nature.
An anonymous salaryman.
- Alliterative Name: Kosaku Kawajiri.
- Awful Wedded Life: His marriage to his wife Shinobu isn't very happy. It probably says something that Shinobu is happier with "Kosaku" when Kira is impersonating him.
- Eerie Pale-Skinned Brunette: Probably not so eerie before Kira took his identity, but definitely after.
- Extreme Doormat: Apologized a lot at work to get promotions and wouldn't respond to Shinobu's attempts to annoy him.
- Impersonation-Exclusive Character: He is only ever seen when Kira is wearing his face as a disguise.
- Innocent Bystander: He got the bad luck of crossing paths with Kira while in Aya's workplace.
- Lethal Chef: Apparently he either didn't cook much or wasn't very good at it. When Kira impersonates him, he makes a delicious dinner and Shinobu is shocked to find out that her "husband" can cook so well.
- Nightmare Face: When Josuke, Okuyasu, Koichi, and Jotaro find his corpse, it's revealed that Kira had not only stolen his clothes, he also stole his eyes, nose, and mouth, by skinning them off.
- Posthumous Character: By possibly seconds, but by the time he appears on-panel, he's already dead, and Kira has taken his face and fingerprints.
- Small Role, Big Impact: While he's just an Innocent Bystander who never appeared in the show prior, Kira murdering him and stealing his identity is what drives the plot of the second half of the series.

Kosaku Kawajiri's wife.
- Adaptational Curves: In the anime she is a little more curvy and busty than in the manga.
- Adaptation Dye-Job: Brunette in the manga, but she becomes a redhead in the anime.
- Agony of the Feet: Shinobu approaching the newly-resurrected Stray Cat in her back garden prompts the flower-cat-thing to blast her big toenail off. Yikes!
- All Girls Want Bad Boys: Kira's actions when disguised as her husband ignites romantic feelings in her. Specifically, the gusto and ease with which he paid the landlord with money stolen from the guy's own wallet. She also gets a bit excited when he briefly loses control of his urges and rips her dress open after asking him help unbutton it.
- Awful Wedded Life: Her marriage to Kosaku prior to him being replaced by Kira was a relatively unhappy and boring one.
- Bare Your Midriff: She wears a short halter top in the Stray Cat episode.
- Housewife: Is the stay-at-home mom type, though not the best at it due to a combination of malaise and lack of skill. She improves her abilities once she starts to feel excited about her "husband."
- Desperately Craves Affection: Stuck in a loveless family with a deadbeat husband and an aloof child, Shinobu becomes quick to throw herself at the disguised Kira when he started showing more affection for her than her husband. When Hayato kisses her cheek, she tears up in joy, showing a woman who just wanted to be loved by her family.
- Hey, You!: She often refers to her husband as anta, a rather rude way of saying "you." After she falls in love with him again, she switches to anata, which not only is a more formal way of saying "you," but it doubles as a term of endearment wives use on their husbands.
- Kindhearted Cat Lover: She owns a cat and claims to have the type of character that is usually liked by cats. Tama being an exception.
- Locked Out of the Loop: She is the only named character who didn't know about the murder of her husband and posthumous use as a disguise for Kira.
- Morality Pet: A downplayed one for Kira. He mostly seems to see her as a nuisance and barely managed to hold back an urge to kill her at first, but after their encounter with Stray Cat it became clear that he had a genuine fondness for and desire to protect her, even if he didn't want to acknowledge it.
- Ms. Fanservice: Most prominent when she constantly tries to seduce Kira, combined with her outfits that show off her legs and midriff.
- Parents as People: She seems to be far more occupied with gaining Kira's attention than actually bonding with her son. Granted, Hayato wasn't very interested in her either before Kira came along.
- She Cleans Up Nicely: Her later design is more youthful in contrast to her homely and unkempt appearance when we first see her. Specifically, the scene where she gets excited from Kira ripping open her dress starts with her more plain appearance and changes to her "prettier" one while she's sitting on the floor both shocked and aroused.
- Single Woman Seeks Good Man: note Kira cooking dinner for her, when her real husband didn't even speak to her unless it was to ask if she cooked something, is a factor in her new love for him.
- Strong Family Resemblance: Hayato gets his appearance from her, if the scene where she lets down her hair is of any indication.
- Took a Level in Cheerfulness: Initially, she didn't enjoy her relationship with Kosaku and was quite moody about it. After Kira took Kosaku's place, she began loving her "husband" and became more happy.
- Yank the Dog's Chain: From her point of view, her husband suddenly becomes more loving towards her. When he's actually been murdered and is being impersonated by a serial killer wearing his face. And then, one day, he disappears forever, and she'll never know why.

A young delinquent who saves Josuke's life when he was four years old.
- Allegorical Character: He represents the human capacity for kindness for kindness's sake. He helps free the Higashikata car simply because it is stuck and contains a sick child and never even sees the people he helped again. He is also the start of Josuke's heroism.
- Anime Hair: A pompadour that Josuke chose to emulate out of gratitude.
- Bit Character: He only has one scene, where he helps the Higashikatas. Justified, as the point of his character is that people can be good and kind just for its own sake.
- Good Samaritan: Had no reason to help save Josuke other than the fact that a child was in danger.
- I Owe You My Life: The reason present day Josuke emulates this guy's hairstyle is because it's Josuke's way to honor the man for saving his life. Consequently, the reason Josuke gets so angry when someone makes fun of his hairdo is because Josuke considers any insults to his hairdo to be an insult to him.
- Identical Stranger: In the anime at least, when seen in the flashback of Josuke's past, he looked practically identical to the present day teenager Josuke (having the same hairdo helps), just with some minor wounds and cuts on his face (which Josuke himself also suffers from time to time).
- Japanese Delinquent: Has the look, though he turned out to have a good heart.
- Mysterious Stranger: Who was he? Why was he standing in the middle of a snow storm while injured?note What happened to him? Josuke never found out the answer to any of these questions.
- No Name Given: His name is never known.
- Small Role, Big Impact: Only appears for a few pages but his act of saving Josuke's life would go on to cause all of Josuke's good deeds.
- The Voiceless: The anime chose not to give him a voice, instead showing his dialogue as cutaway text.

Morioh's radio DJ. Apparently, Okuyasu and Kira are fans, as they've both written into his program.
- Canon Foreigner: He's original to the anime, and doesn't appear in the source material or any other adaptations.
- Cozy Voice for Catastrophes: Provides a calm, relaxing voice against all the sinister things happening in Morioh.
- Foreshadowing: A lot of what he says hints at future Stand users the heroes will fight.
- The Voice: While several "Diamond is Unbreakable" episodes have opened with snippets of his program, Harada himself is never seen on camera.
