JoJo's Bizarre Adventure isn't just popular for the nature of its memes, but its characters as well, even if some of them don't get much screen time, or aren't even human.
- Phantom Blood:
- Robert E.O. Speedwagon is absolutely adored in the fandom for being a total Keet who admires Jonathan and Erina to a fault, and the way he respects William Antonio Zeppeli's death and carries out his mentorship legacy after adopting his hat made him all the more charming to fans. His Uncle Pennybags portrayal in Battle Tendency after forming the Speedwagon Foundation doesn't hurt, either. His popularity earned him a major role in Eyes of Heaven, and his Demoted to Extra status in the 2007 movie adaptation was a common criticism among fans.
- William A. Zeppeli, too, with many considering him the best mentor character in the series.
- Battle Tendency:
- Wamuu is the most popular of the Pillar Men by far for being the Anti-Villain of the trio and for the genuine sense of honor he displays towards the protagonists — who he views as his Worthy Opponents — to the point where he's one of the few secondary antagonists in the franchise that is more popular than the main villain (Kars) of his part. There are fans who admit they can't bring themselves to hate him despite killing Caesar, due to how honorable and respectful he is throughout.
- Despite him being a Satellite Character, Smokey Brown has a rather large following due to him being the series' first black character, being the catalyst for Joseph to show that he doesn't tolerate racism, and his fate of becoming a successful politician.
- Stardust Crusaders:
- The Villain of the Week characters of the Part's first half are often criticized for being rather forgettable Mooks, with some of them not even getting names. However, a number of them still manage to have a following among fans. The most notable of them being Hol Horse (for his cool Stand, Emperor, his very human and likable personality despite his villainy, and providing a large amount of the Part's comedic relief in his second arc with Boingo), Mannish Boy (for his Stand, Death 13, providing one of the coolest fights in the Part), and Midler (whose face is never actually shown in the manga or anime, but has gained a following among Heritage for the Future fans for her attractive belly dancer inspired design).
- The Egypt 9 Glory Gods, the Praetorian Guard characters of the Part's second half, are generally much more liked by the fans. For particular standouts, there's N'Doul (for being a Noble Demon and a Jerkass Woobie, as well as being the only villain to battle all six members of the Joestar group at once and still almost win, incapacitating two in the process), the Oingo Boingo Brothers (for, like Hol Horse, providing much of the Part's comedic relief as well as their seriously catchy ending theme), Chaka (for being The Woobie who has to put up with his unloving family and his Brainwashed and Crazy self providing one of the best-choreographed fights in the series), Mariah (for her beauty, being one of the few female villains in a series mostly consisting of male characters, and her gripping-yet-hilarious arc against Avdol and Joseph), Daniel J. D'Arby (for being Affably Evil and for having a unique, smarts-based battle in comparison to most of the fights in the Part), and Pet Shop (for his status as an ice-wielding bird of prey with a vicious, loyal Creepy Awesome nature, and especially for his brutal and intense fight with Iggy).
- Enya the Hag, despite being a retroactively important villain, isn't exactly a fan-favorite, with many citing her as a Flat Character who mainly runs on Moral Myopia. However, her OVA incarnation has amassed quite a following for not only having more courteous moments to the Crusaders, but also gaining an incredibly sexy disguise
◊ akin to Nena, complete with◊ a Boobs-and-Butt Pose.
- Diamond is Unbreakable has quite possibly the largest amount of popular supporting characters in the series, most likely for its Lighter and Softer tone and larger focus on comedic character interactions than other Parts:
- Yukako Yamagishi only gets a major focus for two arcs in the Part, but she still manages to be as synonymous with the Part as the actual main characters, mostly for being the Ur-Example of the modern Yandere trope.
- Tonio Trussardi is popular for providing a Breather Episode, being a genuine Nice Guy despite Josuke's suspicions of him, and his introductory episode providing a lot of Food Porn.
- Shizuka Joestar only has a major role in a fairly short arc, is basically treated as a Living Prop for the rest of the Part, and never appears again after the events of the Part. Despite all of this, fans have grown to love her for the sheer amount of Fanfic Fuel she generates, and has become a common source of Fandom-Specific Plots because of it.
- Mikitaka Hazekura is popular for the ambiguity of his character and the comedic tone of the arcs he appears in.
- Yuya Fungami has managed to win the hearts of fans as one of the most popular minor characters in the series. His debut arc is considered to be the best of the Part (if not the entire series), his Stand, Highway Star is one of the most popular Stands of the Part, and his Heel–Face Turn and role in the Enigma Boy arc has gained him a lot of fans.
- Golden Wind:
- While Polpo is a relatively liked character, no one would say he's a fan-favorite. His Stand, Black Sabbath, on the other hand, is one of the most popular Stands in the series, for its design and the battle against it. Its fun boss battle in the Vento Aureo PS2 game certainly helps.
- La Squadra is, bar none, the most popular group of Villain of the Week characters in the series. On top of being Anti-Villains (with the exception of Melone), they all prove themselves to be rather cool characters who many fans wish had actually won. Of particular members, there's Pesci (for being Adorkable, going through a surprising amount of Character Development in his short appearance, and even coming close to actually winning his fight against Bruno), Prosciutto (for being a Determinator and a Big Brother Mentor to Pesci, his absolutely terrifying Stand, The Grateful Dead, and for being the most "gangster-like" of the cast), Ghiaccio (for the design and use of his Stand, White Album, his memorable fight, and his Hair-Trigger Temper resulting in one of the funniest moments in the Part), and Risotto (for being A Father to His Men, his intense battle against Doppio, and his absolutely terrifying Stand, Metallica). Even Melone, the Token Evil Teammate, is well-liked due to his Large Ham and hilariously gramatically broken catchphrase in italian.
- Cioccolata is popular for being one of the most unapologetically evil characters in the series, being an Evil Counterpart to Giorno, his amusing interactions with Secco, his absolutely terrifying Stand, Green Day, and for being one of the few Villain of the Week characters with a fleshed-out backstory.
- Stone Ocean:
- Gwess has a dedicated following of fans who consider her underrated and underutilized, wishing to see her role as Jolyne's flunky more than what was shown, and considering her a great Starter Villain for her quirky Bitch in Sheep's Clothing personality.
- Rikiel is quite beloved among the fanbase for inheriting his father's determination and being the most sympathetic of DIO's sons (with the exception of Giorno).
- Pucci's second Stand, C-Moon, despite appearing only in one arc before transforming into Made In Heaven. Its powers of being a Gravity Master makes its battle with the heroes among the most fun and creative ones in the franchise, especially when most of Part 6's fights were considered underwhelming by many in comparison.
- The Made In Heaven-universe version of Jotaro gained quite a bit of memetic popularity once the anime was released, if only due to how much of a Gonk he is compared to the more traditionally handsome Jotaro. Fans have largely taken to calling him "Qtaro Kujo" as a callback to Jotaro's fake sign-in name in Stardust Crusaders.
- Steel Ball Run:
- Ringo Roadagain is quite possibly the single most popular minor villain in the entire franchise, for his cool design, being a Noble Demon, and his Stand, Mandom. He's so popular, that many fans were disappointed to hear that he was considered to be a playable character in Eyes of Heaven, but ended up getting scrapped.
- Blackmore is liked for his cool design, interesting personality, his Battle in the Rain, and for acting as an effective Knight of Cerebus.
- Even amongst minor Villain of the Week characters, D-I-S-C-O stands out for having a very short appearance and only getting two lines of dialogue. This doesn't stop him from being popular among fans.
- JoJolion:
- While Ojiro Sasame started out as a rather forgettable Starter Villain, his return later in the Part earned him a large amount of fans, mainly because he Took a Level in Badass and managed to get the Part back on a steady pace after many fans felt it suffered from Arc Fatigue.
- Kei Nijimura is liked for having a cool design, being a Suspiciously Similar Substitute for Jotaro, and her Stand, Born This Way, and many fans were saddened by how minor her role proved to be after her introduction arc... and then celebrated when she made a return.
- Yoshikage Kira, in spite of being a Posthumous Character, is well-liked by fans for being a complete badass who combines the best aspects of Jotaro and the original Kira.
- Tamaki Damo is one of the most popular minor villains in the series, mainly due to his Faux Affably Evil personality, the coolness of his Stand, Vitamin C, and his role in Josuke's origin, to the point that many fans wish that he had been the Part's Big Bad.
