The casts of the Hiroshi Takahashi mangas Crows and Worst are almost entirely composed of delinquents, specifically Harumichi Bouya and Tsukishima Hana, the respective protagonists. The opponents they encounter can be divided into two distinct groups: Rivals (delinquents who respect the codes of honor and companionship in high school gang warfare) and Bad Guys (jerks).
Tetsuo Shima and Shotaro Kaneda in AKIRA, plus the rest of the Capsules (Kaisuke, Yamagata, etc.) are a violent motorcycle gang. They're attending a reform school, but its goal of turning them into productive members of society seems to be failing — badly. And yes, back in the '80s criminal rebellious bikers in Japan apparently had side-parted hair and wore pink polo shirts.
The main cast in Angel Densetsu. The scariest looking of the bunch, however is a Messianic Archetype, and manages to mellow them all down. (Kuroda and Ogisu remain totally useless people, so they do not count). MostAll of the guidance counsellors too.
Assassination Classroom has a "delinquent" clique within the cast consisting of Terasaka, Muramatsu, Yoshida, Hazama, and later Horibe. They're of the rumbustious rather than the seriously criminal kind.
Sakaki is mistaken for one of these: A Huge Schoolgirl + totally inexpressive + unusually skilled athlete + Kamineko hurts her hand = everyone assuming she's a Delinquent who loves picking fights for quite a few episodes of the series. During the school athletic festival, she and Kagura even hung a lampshade on it by dressing up as delinquents... boy delinquents, but delinquents nonetheless.
Parodied when Chiyo-chan and company dressed up as delinquents during the Sports Festival.
Also parodied during Kaorin's hatsuyume (the first dream of the new year), when all of the girls (except Sakaki) are wearing face masks and long skirts, implying gang membership. Then Sakaki rides in on a white horse, knocks them down, and sweeps Kaorin away. Kaorin was quite disappointed to wake up just then.
Be-Bop Highschool has the two laid-back main characters.
Each and every student of Ishiyama High in Beelzebub. The main character himself is the top delinquent, who rules the entire institution. It's questionable how the school qualifies as a school seeing as it's basically gang headquarters for all the delinquents in the general vicinity, while the only faculty employees on campus are the principal (who doubles as the janitor) and the lunch lady, while the school building has gotten destroyed twice already. And theirs isn't the only delinquent school in the area!
Rantaro from Beyblade Burst has the looks and brash personality. He has a blond pompadour, wears his gakuran open and as a cape (despite the fact that his school doesn't even use uniforms), near permanently keeps a lollipop in his mouth, and has a bandage on his nose.
Magna Swing from Black Clover has this image to a T with the chain, dark shades, dyed mohawk, leather jacket and boots, and tough guy attitude. He's even called "Funny-Glasses Delinquent" by others.
Ichigo Kurosaki in Bleach. Subverted as most of the fights Ichigo got into were people picking fights with him, often because of his hair, which is naturally strawberry blond. He himself hates being seen as such.
Bunny Drop has Kouki act like this as a teenager, even dyeing his hair and having a delinquient girlfriend. Rin is not impressed by this.
For the first half, Campus Special Investigator Hikaruon plays like an old-school delinquent manga with the lead embodying the demeanor in class.
A Certain Magical Index: The Level 0 street gangs known collectively as "Skill-Out" are depicted in this manner. One of the three protagonists, Shiage Hamazura, is a former Skill-Out member. Indeed he was rather highly placed, being second-in-command of one of the largest gangs in the city. Kuroko's senior officer in Judgement, Mii Konori, is also a former Skill-Out, although the particular gang she belonged to was a rather benign one that didn't commit crimes.
Chameleon is all about the main character wanting to be Japan's biggest bancho.
Tomoya Okazaki and Youhei Sunohara in CLANNAD are known as these, due to their tendency to skip classes. Sunohara's tendencies to pick a fight and be naughty (but always fails) doesn't help. However, the real delinquent would be Sakagami Tomoyo, who actually became (in)famous for it. By the time the story starts, she renounces her delinquency to be eligible to become the Student Council President.
Pretty much everybody in Cromartie High School is a delinquent, although they split their time equally between having odd conversations and fighting rival schools.
One of the two protagonists in Crossplay Love: Otaku x Punk, Shuumei Satogiri, is a yankii who dresses as a girl to get close to the girl he likes — who unknown to him, is also a crossdresser. Even as "Mei", some of Shuumei's Hot-Blooded nature shows through.
Joe Shimamura's original backstory in Cyborg 009 had him and his friends as one of these. It's bowdlerized in the new series, where they are Heartwarming Orphans instead.
Delinquent In Drag somewhat parodies this, but all the main characters fit.
Masaru Daimon of Digimon Data Squad is a banchou and a street fighter, and it really showsnote the dub Bowdlerised this into him being a loosely-defined "ultimate fighter". He actually needs to punch a Digimon to trigger his DigiSoul, and more often than not his punches do more damage than any of the ally Digimon. Meanwhile, BanchouLeomon is pretty much Exactly What It Says on the Tin: a humanoid lion themed after a banchou; however, he instead fills a mentor role.
Kida Masaomi, ex-leader of the Yellow Scarves, Ryuugamine Mikado, current leader of the Dollars, and Heiwajima Shizuo, when he was in high school, although that wasn't entirely by choice but just all those myriadBerserk Buttons flooding to the surface.
Many of the characters here are members of the Dollars, who aren't your usual delinquents since most of them are regular people who joined for kicks. There's another gang of note who are really the only one from the show that really qualifies, the Yellow Scarves, which used to be in power some time ago. Izaya seems to put down Saika's children as another faction that has infiltrated the other two.
Eyeshield 21 also has Jumonji, Kuroki, and Togano (the "Ha-Ha" Brothers, from habit of going "Hah?" in sequence when confused), three punks who initially pick on Sena, but end up getting recruited as linemen for the Devil Bats and becoming his friends.
Arisa Uotani (and in her teenage years, Honda Tohru's mother, Kyoko) in Fruits Basket. Kyouko's case in special in that she actually used to be a legendary delinquent known as the "Red Butterfly" due to the trail left by her red bike, and Arisa used to idolize her... too bad this coupled with Kyouko being a badly-abused Broken Bird, and her delinquent behavior was an outlet for her inner pain.
Gang King has basically every male as a delinquent in gangs, etc.
Kodaka, the protagonist of Haganai, is mistaken for one by his peers due to his naturally-blond hair and ostracized as a result; his reputation is shown to have some benefits as well, however, which he doesn't mind exploiting.
Mamoru Takamura. Even in the ring, he rocks the pompadour and has the extreme Jerkass personality to match. He started boxing in order to keep out of trouble and it took him far. Also, Takuya Kimura and Masaru Aoki, though they had to reconsider their delinquent status once they ran into the force of nature that is Takamura.
Takeshi Sendoh and Ryuuhei Sawamura as well. In Sendoh's backstory, we learn that he actually became a delinquent and gang-leader in order to protect his classmates.
Hana no Asuka-gumi is a wildly popular shoujo variation of this trope.
The main character in Hareluya II Boy may count as one and he and his group run into a number of these.
Harlem Beat: Kiriko, Kosuke, Sawamura love to smoke, gamble and skip school. And then there's the Kyan team.
Katsuya Kimura from Hell Teacher Nube. Waaay older than he should be for a fifth-grader, smokes, often associates with less than savory elements, openly lusts for Miki, and often the root of serious trouble for Nube and his classmates. Then again, he's a Jerk with a Heart of Gold that would put his life on the line for his friends, loves animals, is very kind when you get to know him, and is unbelievably protective of his little sister Manami.
England from Hetalia: Axis Powers was said to be quite the delinquent as a teen, something which he fervently denies due to his current status as a (self-proclaimed) gentleman. This is also touched in Gakuen Hetalia where in England's official bio it mentions how he had been given such a reputation in the past.
Hungry Heart: Wild Striker: Kyousuke Kanou began the story with the appearance of one, having his hair dyed red-orange and picking fights with street thugs. As the story advances, it's revealed that he became this in an effort to distinguish himself from his brother Seisuke, to whom he was constantly compared.
Idol Densetsu Eriko: Eriko's sempai Yasuko is the archetypal "tough girl", who likes fighting and motorbikes, and is mentioned to have been expelled from school. She's on Eriko's side come what may, though.
Tobitaka Seiya in Inazuma Eleven is the formerly leader of a gang of delinquents, who was known as "Tobi the Kicker" due to his excessive use of legs in fights. Coach Hibiki (who was a delinquent himself in his youth) sees potential in him and suggests him to play soccer, something his kicks would be useful for.
Airs Blue from Infinite Ryvius, a gang leader who gets his hands on the only gun on the Ryvius.
Keisuke Takahashi in Initial D used to run a delinquent gang when he was younger, before he started street racing professionally with his brother. It pays dividends in Fourth Stage when a rival racing team hires a bosozoku gang to attack Project D for beating them fairly; as it turns out, the gang's leader was one of Keisuke's former subordinates, and he does not appreciate being hired to beat on his former aniki.
Inuyasha: Honorable mention: Kagome's trio of friends at school interpret her evasive descriptions of Inu-Yasha as describing a yankii boyfriend.
Subverted with Jotaro, Josuke, and Okuyasu. Jotaro may be a self-proclaimed punk with his highly unorthodox school uniform and rude attitude, but he's well-read and doesn't try to deliberately cause trouble. Josuke and Okuyasu on the other hand may look like stereotypical Japanese delinquents with their pompadours and customized school uniforms, but they're pretty friendly and respectful to others. In fact, Josuke himself gets bullied by actual Japanese delinquents in his first chapter (that is, until they insult his hair).
Jotaro's daughter, Jolyne, was a delinquent in her teens, but she had straightened herself out before her story begins.
Played more straight with Yuya Fungami, who has the looks, is a gang member and even a trio of fan girls that carry weapons like the typical female Japanese Delinquent. Even then however, he manages to side with Josuke after his initial antagonistic role.
Kagerou Daze: Invoked (but subverted) by the main cast, since they're a gang. Kido especially tries to create this image to appear tough (one pant-leg rolled up to the knee, hood always up, high collar hiding bottom half of her face) and make her gang look cool, but in reality she's actually very friendly, and quite shy. The rest of the gang have minor design details that indicate this kind of image (for example, Momo's two-tone bleached hair), but they don't really do much that would indicate delinquent behavior (Kano's Consummate Liar tendencies not-withstanding).
Kill la Kill: Ryuko Matoi admitted she started to pick fights when she was very young, and became a full-blown delinquent by her first year in high school. One of her adversaries, Uzu Sanageyama used to be one in his middle school days. Mako's uniform as president of the Fight Club, meanwhile, evokes this, consisting of a Coat Cape, chains, a nailed bat, brass knuckles and a clover straw to chew on.
Madoka Ayukawa in Kimagure Orange Road is a particular example: despite her heroic personality she has a very bad reputation as a delinquent because she's able to fight against real delinquents. In fact she is believed to be a sukeban, and she's feared and hated due to the bad fame she acquired. In the first episode she takes on and defeats five male delinquents. In a filler one she has to face a bunch of other girl delinquents who think she has messed around with their leaderess, and beat up Hikaru as revenge. It's a misunderstanding, and said leaderess is very angry when she finds out.
Almost the entire cast (both main characters, minor characters and even one-shot characters) of Kyō Kara Ore Wa!!, as the protagonist is one and tends to interact mainly with other delinquents.
Hatori from Life (2002). She's not in a gang, and she doesn't fight people, but she has quite the reputation. Most of it is just rumor though.
ViVid Strike!: The Protagonist, Fuka Reventon is frequently gets into scraps with entire gangs due to her violent temper and subsequently gets into trouble with the police. As a loner orphan, this did not help her living conditions as she's been kicked out from various jobs and from her orphanage due to all the trouble she causes.
Metsuko ni Yoroshiku has Akiko and her two friends Yuzu and Kaoru (though Kaoru never takes part in their activities, she just kind of hangs out with them). By the time of I Can't Understand What My Husband Is Saying, they've all become Former Teen Rebels. Hilariously, while Kaoru does have bleached hair, she only started doing so after she got married.
Seiji Sawamura; sure, he gets into fights, argues with teachers, and does horribly in classes, but if you so much as touch one of the students of HIS school, he will punch you through your car.
And his sister's way tougher than him.
Haruka Minami from Minami-ke apparently had a history of delinquency as many characters speak of her having been a 'legendary' banchou. She spends most of her screentime being a niceMs. Fanservice, but the heavy handed way she solves a few problems hints that the rumors might be true.
My Deer Friend Nokotan: Class Princess Koshi is mortified about her past as a "Yankee", a violent, crude street punk. In flashbacks, she's seen with the whole nine yards: long Sailor Fuku skirt, baseball bat with nails in it slung over her shoulder, face mask with an X on it.
Yuuichi from My-HiME (both the anime and manga, although the circumstances are different in each) used to be a delinquent until he ran into Shiho, who helped him overcome those tendencies and has looked up to him as a "big brother figure" ever since.
Naruto Uzumaki from Naruto starts this way at the beginning of the series. He even gets the standard yankii uniform during the High School AU ending credits (and the Shippu Konoha Gakuen Den special that was inspired by it) and wants to be in the yakuza.
The characters of Nyankees are all drawn as delinquents, though without the school setting and slightly older-looking. But they're not even human, they're street cats!
Metal Bat from One-Punch Man is modeled on this trope, being a parody of characters like Yusuke Urameshi. He's easily one of the most heroic people in the series, though.
The cast of Ore-sama Teacher is full of them. Pretty much everyone either used to be a delinquent, is a delinquent or is trying to quit being a delinquent. The internal justification being, although being an Elaborate University High, Midori ga Oka has a serious enrollment issue. As a result, it accepts nearly any transfee, a lot of them being previously expelled due to this trope.
According to the "The Bridge Bike Gang" episode of Pokémon: The Series, Jessie and James were delinquents as teenagers before becoming Team Rocket (which is yakuza inspired) members as adults.
Kyoko Sakura in Puella Magi Madoka Magica is one of these by way of Pater Familicide. She's very violent and abrasive, ties her hair with a bandana, and wanders the city stealing food and money to sustain herself while leaving weak people to die and generally causing commotion. Yet she turns out to be a Jerk with a Heart of Gold, true to this trope.
Hayato Gokudera in Reborn! (2004) Kyouya Hibari and his followers, though they are also the Disciplinary Committee and are delinquent only in the name of their school which Hibari really, really loves. Ironic much?
Nearly everyone in Rokudenashi Blues is a delinquent, although the main characters try not to pick fights.
In an episode of the anime, after Tsukune had been kidnapped by a gang of delinquents (monster delinquents, at that), the main group of girls dresses up as stereotypical high school delinquents to fight the gangsters and save him (though that was more for show than anything else, since it was an idea from resident cosplay fetishist Ruby).
In the first manga, however, the deliquent gang called Anti-thesis served the main antagonistic group. The Committee of Public Security did count as well, acting like the mafia. The former group was founded by Kiria Hoshi who used it to spy on the Yokai Gakuen for Fairy Tale, the main antagonistic group of the whole series. Both leaders of the two said groups, Kuyou and Hokuto, joined Fairy Tale later on.
Sanosuke Sagara in Rurouni Kenshin. Though not a school student, he fits in every other respect.
Sailor Moon: Makoto Kino (Sailor Jupiter) was originally conceived of as a smoker and sukeban leader in Codename: Sailor V, but in the final published version, the character just kept the pseudo-yankii design of a long skirt and curly hair. This and her unusual height and strength makes people assume she's a delinquent, but in fact she keeps the long skirt from her old school because there wasn't anything in her size, and her curly hair is natural.
Sakigake!! Otokojuku has a whole class of Japanese Delinquents trained to hone their honor and friendship with each other to the point where you can't call them "delinquents" anymore.
Kenji Harima from School Rumble fits as one of the major-character type, complete with getting into fights, riding a big bike, and wearing an open jacket.
SD Godzilla World: Godzilla Kun, a Godzilla gag manga by Super Mario-kun author Yukio Sawada depicts King Ghidorah as a bancho with Gigan as his crony.
Shounan Bakusozoku (a.k.a. Bomber Bikers of Shonan) is one of the most popular entries into the Delinquent genre (in Asia anyway). Its premise is a parody of the trope (Eguchi isn't only the leader of the Biker gang but also of the school's handicraft club), but the series plays it straight quite often.
Himeko from Sket Dance was one at first, but she changed.
The Story Between a Dumb Prefect and a High School Girl with an Inappropriate Skirt Length: Yuu Izubuchi, the health committee representative, is a former delinquent (apparently the student council president got him to quit), but he still looks and acts like one. When the president calls for more people to collect donations, he calls up a crowd of delinquents to help.
Tono to Issho: Maeda Keiji, as the narrator likes to remind us, would be considered one nowadays. Which means that he's a Jerk with a Heart of Gold who rescues stray kittens.
Ryuuji, the protagonist of Toradora!, is similarly feared by most other students due to his intimidating face (the white part of his eyes is unusually large), which he inherited from his father — a violent yakuza. Ironically, he's a Nice Guy and not a delinquent at all. Taiga, on the other hand, sometimes behaves like one, and is shown with a bokken in the title sequence.
Ultimate Teacher is a parody of the Delinquent genre, set in Japan's worst school. The school's leader, Hinako, is the school's prettiest (and cleanest) girl and the teacher that's supposed to straighten them out turns out to be the biggest bully of them all.
In Why the Hell Are You Here, Teacher!?, "Lone Wolf" Minamoto-sensei was formerly a yankii and supposedly beat up 50 guys by herself, uniting biker gangs across the country.
The main villain, Duo Haguro, of Wolf Guy - Wolfen Crest is supposedly a yakuza (or at least a yakuza heir), but due to his age and status as a high-schooler fits many aspects of this trope. His student underlings and his girlfriend Ryuuko Kounuma also qualify.
The entire main cast of Yankee-Kun to Megane-Chan (Flunk Punk Rumble in English translation) is made up of people who are, used to be, or everyone is convinced are delinquents.
Yandere Kanojo has several, most prominently the female lead, Reina Ryuuzaki, as well as some of her old delinquent friends and rivals as minor characters. The title of the manga is even a pun on Reina's nature as Manabu Tanaka's yankee but dere dere girlfriend (rather than her going yandere).
Onidere is very similar to Yandere Kanojo in this regard, with a delinquent female lead and her gang friends as secondary characters.
Yusuke Urameshi, who calls himself a super delinquent. He has problems with authorities, beats up bullies and other delinquents and he's very rude. The fact that he saves a little boy from a car accident (that wouldn't have injured the boy) is the reason why he got a second chance in life because it's such a big surprising act of selflessness.
Kazuma Kuwabara fits the trope even better than Yusuke, since not only is he a Jerk with a Heart of Gold, but he has an open jacket, wears a "Sarashi", and has a bright red pompadour.
Also Asato Kido and Mitsunari Yanagisawa, two of the three relatively minor characters Genkai recruits for a Secret Test of Character and the story arc that follows. They don't have a very big part, but they do show up in the background for the entire arc.
Saki of Zombie Land Saga used to be second-in-command in a biker gang that terrorized Saga, before she died in a biking accident. When brought back as a zombie as part of an Idol Singer group, she retains her gruff and threatening personality, to the point where "You wanna die?" is her catchphrase. She takes over the group as leader and does slowly warm up to the others as the series goes on; she spells out her personal philosophy in the sixth episode, that all anybody has is their guts and their crew. Her Day in the Limelight episode sees her getting involved in her old gang's problems, as she deals with her old boss Reiko's strained relationship with her daughter, now the gang's current boss, and the gang getting in over their head against a rival gang.
As minor characters
The Capsules, Kaneda's bosozoku gang from AKIRA, a rival gang called the Clowns, and many of their classmates.
At the end of the story, Nagisa has to deal with a whole class of stereotypical delinquents in his first teaching job.
There's also the stereotypically delinquent group of older students who kidnap and threaten to rape Kayano and Kanzaki on the school trip to Kyoto.
The class of Battle Royale features a small group of delinquent males led by Empty Shell Kazuo Kiriyama. An even smaller group of females is led by Souma. Both are especially hardcore examples who get involved in serious and violent crime.
Blassreiter features a group of delinquents who antagonize everyone in their path from fellow schoolmates to Useless Adults with no fear of reprisal (their ability to manipulate characters and to escape karmic retribution is rage-inducing, but largely for how obvious a rage plant they are). Physical and verbal dog-kicking abound, in addition to forcing Malek's friend Johann to commit suicide. These three school seniors seem to run their neighborhood, and for all we know Japan, with an iron fist until their reign eventually comes to an end as Malek fittingly murders them during the second arc of the series, but the sour taste of their deeds doesn't wash out right away, as much a result of the implausibility of their overblown dog-kicking as the heinousness of it.
Bleach, particularly in the flashbacks of Ichigo and Chad's past. More exactly, Chad used to be a delinquent but mellowed out and later refused to fight other punks, and when he was harassed by a whole gang Ichigo defended him, which is what kicked off their friendship. Ichigo is often frequently assumed to be one because of his orange hair and bad attitude.
An attack on girls wearing inappropriately high heels reminds Chief Megure of an older case where some delinquent, long-skirt wearing girls were targets of a hit-and-run driver. The Sole Survivor of the case is currently his wife, Midori.
One of the murder suspects in the "Timeless Cherry Blossom Love", Kikuna Kagitani, is a foul-mouthed ex-delinquent who still bleaches her hair blond and claims to be able to summon many other girl delinquents to do her bidding.
Subverted for multiple times in Daily Lives of High School Boys. Motoharu is called one and looked like one, but he's more a Nice Guy. This goes with most of the Sanada North's School Council sans the Student Council President; all of them have a serious case of Face of a Thug despite being actually sensible and well-mannered guys. Lampshaded when the other school's Student Council arrives at the council room and first thought they went into a delinquents' office by mistake.
Light kills a delinquent in Death Note while experimenting with its power.
Chi-Chi's eternal fear in Dragon Ball is her son Gohan turning into one of these if he stops studying and train in martial arts. Considering the type of story Dragon Ball is, she's woefully unsuccessful, at least for the first three arcs.
In the baseball episode of Excel♡Saga, the whole class is made of these ridiculous stereotypes. The toughest of the bunch has a pompadour haircut that extends a good fifteen feet from his forehead and appears to be prehensile...
The Zokugaku Chameleons from Eyeshield 21 are an entire team of minor-character delinquents, except for team captain Rui Habashira, who's more like a secondary character (and placed 5th in the latest character popularity poll).
Subaru Mimasaka from Food Wars! is a hulking Badass Biker who wears a tracksuit, earrings, and has his hair shaved except in the middle, where it's tied in several long braids. He's also a Genius Bruiser when it comes to cooking.
There is a trio of middle-school-aged yanki wannabes who tried to pick a fight with Uotani after stalking her for over an hour. Uotani is easily able to talk some sense into them.
Uotani used to be one herself, until Tohru's mother Kyoko (who was also in a gang when she was her age) convinced her to change her ways and quit the gang. Other students still call her a delinquent though, mostly Kyou, because of her rough speech and how she still wears a very long skirt.
In Full Metal Panic? Fumoffu, a gang of delinquents attempts to mess with Sousuke, first by picking a fight with him and then kidnapping Kaname, only to find they are not prepared to deal with someone like Sousuke. Though to be fair, there aren't many people that are prepared to deal with someonelikeSousuke.
See Yankumi's students in Gokusen. Ironically one of the teachers is a real Yakuza princess, compared to the delinquent students in her class. Being delinquents, most of them are too dense to have figured it out.
Great Teacher Onizuka. If you're not sure what the minor-type is supposed to look like, see the class Onizuka deals with in the first couple of episodes.
Ippo's fellow boxers Aoki and Kimura were both juvenile delinquents in their backstory, constantly fighting with groups from other schools. Then they got beaten up by Takamura and they stopped being delinquents, instead becoming boxers so that they could defeat Takamura. Well, TRY to defeat him. There's no question that Takamura is leagues above the other two.
Haven't You Heard? I'm Sakamoto: Several of the boys in Sakamoto's class are delinquents who try to make Sakamoto look bad since all the girls only have eyes for him. Sakamoto ends up befriending them and even gets one of them to quit smoking. He later serves as upperclassman delinquent Maruyama's errand boy, and helps out their leader Hayabusa after defeating him in a "fight".
In Helen ESP, Oguri's brother Midou is one, though he ends up reforming.
In Chapters 25 and 26, Hitomi wears a gakuran uniform with the shirt unbuttoned and sarashi covering her breasts, looking very much like a delinquent.
An episode of Kirarin☆Revolution has Kirarin's rival Erina thinking that her image as a cute idol isn't working because Kirarin adopts the exact same image and has more success than her, so she goes the opposite way and starts dressing up as a delinquent schoolgirl and taking the role all time long, which includes singing her trademark Sickeningly Sweet song in deep, menacing voice. She later realizes that changing your image so drastically is not the right thing to do... so she goes for the opposite way and changes her image to a super cutesy idol in a doll-like outfit.
Episode 67 of Kirby: Right Back at Ya! features Dirk, Kirk, and Smirk, a Terrible Trio of unruly bullies from Nightmare Enterprises who can't resist having fun picking on others, especially the teachers, and can combine together into a three-headed totem pole-like monster called MT2. It's rather unsurprising when you learn that these three were inspired by Japanese delinquents, and Smirk is based on a bancho, much like his Japanese name suggests.
Jirô in Neighborhood Story. The other characters sometimes start talking in delinquent slang while he looks at them with a pissed expression from the background.
Maid-Sama!'s cast are forced to go on a "rescue mission" (and end up forgetting why they went anyway) only to have the Three Idiots make up with an old ally. They all dress up in delinquent-style clothing for the infiltration.
Rin's motorcycle gang (and in the manga, the all-female gang led by Miku) in Midori Days.
Episode 17 of My Bride is a Mermaid is a spoof of this idea, with Akeno being forced into being a gang leader. Sun's idea of an ideal man is also a stereotypical bancho.
Saki Kawasaki fits in the look: tall girl with white/light purple hair, doesn't use all the official uniform and have the attitude, but she's not a delinquent. Hachiman Hikigaya seems her as one at the beginning.
Also happens with Kakeru Tobe at the beginning of the series, in which rumours said he was a delinquent that made havoc in the neighborhood. Elucidate and clear this is one of the first missions of the Service Club, but the fact his look fits here too, starting for being a red-headed bully, doesn't help him too much. In the end he was just a Jerk with a Heart of Gold.
The "Bancho Rengoku" (Gang Leader Alliance) attacks Momotsuki Gakuen in episode 13 of Pani Poni Dash!. They consisted of a Girl Ninja, A 50-foot man and a talking bull. There's also the character of Yanki, who dresses like a delinquent but is just a fat, goofy-looking doofus.
Pokémon: The Series has one in the episode "The Bridge Bike Gang", parodying the "Bowzock" gangs of Japan as well as being a Pragmatic Adaptation of the Biker trainer class from Pokémon Red and Blue. Jessie and James were in a biker gang as kids as well.
Aruma, the protagonist of Sacred Seven is in a similar situation, although the real yankees pick on him themselves.
Some secondary characters in Slam Dunk are delinquents, in a wide range of positions from street gangs to players in rival teams. As mentioned below, the main character used to be one of these in the past (and is still feared as such).
Tengen Toppa Gurren Lagann episode 15 introduces a leader of group that were inspired to rise up by Team Dai-Gurren named "Bachon" possessing the typical traits such as school uniform with ragged cap, sarashi around the belly and a piece of straw in the mouth.
Tiger & Bunny's first drama CD shows that Kotetsu Kaburagi toed the line of delinquency as a teenager, although he'll protest. It's not his fault that his self-prescribed superhero training required skipping classes to beat up street thugs.
There is a youkai in Yo-kai Watch named "Roughraff" who is responsible for most of the world's delinquents. He is a reptile looking yokai with a large orange pompadour who wears a sarashi. His evolution is also a delinquent.
Whisper: Roughraff preys on teenagers, turning them into youth offenders. We're talking about sassyness, no-good shenanigans, and reckless tomfoolery. Things adults look back on and regret.
In one episode, Roughraff inspirits Jibanyan, turning him into the delinquent Baddinyan. His delinquent acts, however, are simply Poke the Poodle actions like eating two chocolate bars before dinner and letting the crumbs fall on the bed.
In Yo-kai Watch: Shadowside - The Return of the Oni King Touma accidentally bumps into a large pompadour-wearing delinquent. After insulting him and his friends, they take Touma out back, beat him up, and steal his money. After being inspirited, Touma ends up beating them up.
Yui, prior to her black self's sealing with the Sanzo Chains, had conquered every delinquent gang in the country.
Half of the early chapters feature bullies hunting Yui looking for revenge. And all the later chapters are about superpowered girl delinquents hunting down Yui Kamio.
