I'll bet you want to know why I'm here, right? READ THE MANGA.
The main character. He starts off relatively normal, but as the manga attests 3 chapters in, he'd have to be just as crazy as the rest to stay there.
- Adorkable: My god. He pushes it to the absolute extremes sometimes to the point where it becomes downright cringe worthy.
- All There in the Manual: the reason he gives for being in Cromartie is only in the manga and the movie.
- Badass Biker: When he goes on adventures with Mechazawa's motorbike form. However, even Kamiyama admits that Mechazawa does most of the work and doesn't even need a rider to steer himself.
- Beware the Nice Ones/Berserk Button: Although he will usually plead for the least violent way to solve situations, he won't hesitate to shoot at people harrassing innocents in the street with explosive missiles. And he does it completely stone-faced, at that.
- Discussed the Beware the Nice Ones trope to the other saying that when he said "I'll kill you" it sounds way more threatening than the loud delinquent.
- Breaking the Fourth Wall: Does this quite a bit in the earlier stories, especially in the anime.
- Demoted to Extra: What happens to Kamiyama as the series progresses. It was most likely intentional on the part of the author — perhaps intended as a parody of other stories where the protagonist recedes into the background due to the far more interesting and/or amusing supporting cast. Kamiyama explains why in the last episode.
- Extreme Doormat: at first, and always at his old school.
- Felony Misdemeanor: When asked whether he ever has done anything bad, he confesses to doing something so terrible that even his classmates are astonished. Gluing the 37,042nd domino to the ground so it wouldn't fall over when his group was trying to top the record of 37,041 dominoes in a row.
- Flanderization: Kamiyama starts out as just sort of a strait-laced dork who then evolves into an uberdork whose moral fiber leads to incredibly questionable trains of thought. The author seems to suggest that Kamiyama has been this crazy since the beginning, and that it's starting to surface now that he has been among the Cromartie students for too long.
- Killer Rabbit: Hayashida vouches for him based on this principle. If he goes around a school full of badasses looking like a nerdy loser, he must be the toughest one of all. Turns out he's wrong, but pretty much everyone believes it.
- The Leader: Ends up being voted as the "Boss" of Japan due to being the only one able to answer a simple question. If nothing else, being somewhat more groudned than his companions they mostly listen to him.
- Loser Protagonist: He's a complete loser in pretty much every feasible way. There is absolutely nothing cool about this guy.
- Mistaken for Badass: Somehow manages to regularly get mistaken for the biggest badass in the series.
- Neat Freak: Along with all of his other exaggerated moral traits, he's one of these.
- Non-Action Guy: Not that anyone ever really does much fighting, but it's made very clear that he's a terrible fighter.
- Only Sane Man: A parody of this in a way. He's not sane by any means, it's just that his form of insanity makes him a lot more coherent than most of the other guys.
- Ordinary High-School Student: Sort of. In a school full of bizarre delinquents, he comes off as this, but in reality he's way too much of straight laced stick in the mud to be considered normal.
- Straight Man: Relatively speaking.
- Took a Level in Badass: Briefly, once Mechazawa is turned into a motorbike. See below.
- Class: 1-2

Not to change the subject, but...
Kamiyama's right hand man.
- Blatant Lies/I Have to Go Iron My Dog:Hayashida: I got club practice and stuff.Kamiyama: What club are you in?Hayashida: Oh, it's the... Uh, what was it? Oh, yeah, boxing! The boxing club!
- Though it is subverted by the end of the chapter.
- Delinquent Hair: His mohawk. It's a fake. He keeps a normal slick hairstyle under a sort of toupee on which his mohawk is placed, because his family wouldn't accept him trying to be different - so he doesn't show up at his home with his mohawk on.
- The Ditz: He can't even manage a simple word problem that amounts to five minus two.
- Expressive Hair: again, the mohawk.
- The Lancer: He's Kamiyama's right hand man.
- Only Sane Man: Another one of the more coherent guys, though he's probably the least coherent of the group.
- Wrong Genre Savvy: Assumes Kamiyama is absurdly tough despite looking and acting like a weakling based on the Killer Rabbit principle. In reality, Kamiyama really is a weakling.
- Your Cheating Heart: Is revealed to be in a relationship with a married woman in the manga.
- Class: 1-2

You guys are real assholes, you know that?
One of the saner ones. Gets no credit.
- Butt-Monkey: No character is safe, but Maeda gets absolutely no respect.
- Distressed Dude: The most likely character to be kidnapped. No one rescue him
- Expy: A parody of real life wrestler Akira Maeda.
- I Just Want to Have Friends: One of the main reason he hangs out with the students is that they're the closest thing he has that passes as friends. Pointing out that his points are mean for a friend to say makes him temporarily forget the validity of his complains.
- Informed Ability: The only delinquent of the main cast to avert this in the manga. Maeda is shown on-screen effortlessly countering a Yakuza and would have likely won had it been one on one.
- No Respect Guy: Despite being one of the most respectable characters. And all because he doesn't have a badass nickname.
- The Smart Guy: Certainly comes off as the most intelligent character, even compared to Kamiyama.
- Only Sane Man: Another one of the more rational students and thus one of Kamiyama's closest friends. Maeda is the only character that realizes Kamiyama is kind being crazy or going off tangent.
- Class: ?
"Is this guy a student here? Is he even Japanese?"
- Ambiguously Human: Freddie is sometimes referred to by the others as something inhuman, and sometimes acts strange (Well, more strange than he normally does).
- When he gives gives directions to a lost cab driver, the students say he might be using his animal instincts.
- When Maeda has an image in his mind of a group of animals, Freddie is among them.
- Badass Mustache: He's not based on Freddie Mercury's clean-shaven days.
- Cool Horse: He travels exclusively on Koku-Oh.
- Leitmotif: The Suspiciously Similar rock riff based on Queen's "Procession" that plays whenever Freddie shows up.
- No Celebrities Were Harmed: Freddie is clearly (somehow) Freddie Mercury, the plainly deceased frontman of the band Queen.
- No Name Given: Nope, not even on the school's roster.
- Shout-Out: To Queen's frontman, Freddie Mercury.
- Stripperiffic: Bass High seems to think this is his Summer Uniform.
- The Voiceless: Hayashida points out that makes him less advanced than the seal since the seal can growl and yelp to communicate.
- Walking Shirtless Scene: Always shown without a shirt.
- Class: 1-1?
- Amplified Animal Aptitude: Gorilla's crazy antics.
- Everything's Better with Monkeys: he ends up with two other gorrilas for reasons unknown other than makes thing better
- No Name Given: The author explicitly stated that the Gorilla's name is " Hiromi Go". But, it's hardly as if gorillas can introduce themselves, hence, within the story, Hiromi Go, like Freddie, is called whatever the students decided to call him. They didn't prove particularly creative in either case - though at one point everyone is convinced the gorilla is named Hajime.
"My name is Yutaka Takenouchi, and I have only one weakness... I am VERY susceptible to motion sickness!"
- The Big Guy: The toughest of the guys. He's huge and burly and is apparently a great fighter.
- Catchphrase / Once an Episode: His stock introduction. At one point, he screws up his intro and says "My name is motion sickness."
- The Leader: He's the leader of the Cromartie first years.
- One-Man Army: Offscreen but he beats a group of bikers in the manga all by himself after trying to overcome his motion sickness with a bicycle.
- Unstoppable Rage: Beat the hell out of everyone in a train including yakuzas when his motion sickness comes back.
- Weaksauce Weakness: Motion Sickness.
- Why Did It Have to Be Snakes?: Most plots involving him just happen to be school trips. He even lampshades how the school takes many more, longer trips than it should ever be able to afford.

An upper-class individual with aspirations of world domination, Hokuto starts at an appropriate level, taking over one high school at a time. Unfortunately, he then transfers to Cromartie, which doesn't have a structure he can easily take over.
- Bishōnen: Well... comparatively at least. He has long hair and a leaner build than most of the other guys, looking over all more attractive.
- Catchphrase: "All people are PIGS!"
- Consummate Liar: He tries covering up for his transfer error by coming up with ridiculous lies about him fighting his father who leads a dark regime.
- Custom Uniform: He has a white uniform to show off his wealth. Also because he went to the wrong school and thought white was the uniform.
- Defrosting Ice Queen: He comes to genuinely care for his classmates, but you'd never get him to outright admit it.
- Dream Sequence / Imagine Spot: Many. Sometimes, those dreams are the one detail of a story to actually get into the anime.
- Sanity Slippage: Starts out as an Only Sane Man (albeit a snobby one) but quickly begins losing it after seeing how insane Cromartie is.
- Sheltered Aristocrat: He has problem socializing with the comoners.

You mean, you're really interested in me? Okay. My name is-
Exactly What It Says on the Tin. Followed Hokuto to Cromartie.
- All Take and No Give: Played for laugh from Hokuto's perspective during a dinner, Hokuto realizes he is the only one aside his rival to put meat on the plate while everyone only talks while taking a bite. The lackey is especially greedy with the meat which annoys Hokuto to no ends.Hokuto: I like what he is saying, but the way he holds his meat makes me want to kill him.
- Butt-Monkey: Every time he tries saying his name.
- Everyone Calls Him "Barkeep": To the point they refuse that he stops being a lackey to Hokuto.
- Hey, You!: Because no one's interested enough to know Hokuto's lackey's name.
- Satellite Character: Originally, though he gets more appearances and screentime than Hokuto himself in the manga. The author implied that the reason for this is how Lackey is easier to fit into any given story.
- The Un-Reveal: Hokuto's henchman tries to reveal his name to the others. "Listen and listen good! My name is..." "Look! A meteorite just crashed into the school! "THIS ISN'T POSSIBLE!" Even when he was out on a date with a girl in volume 11 of the manga and had the chance to introduce himself to his date's friend's boyfriend, he STILL gets interrupted.
- Withholding Their Name: Inverted and Played for Laughs because Hokuto's lackey frequently gets cut off before he can say his name. The background and author notes in the manga finally does reveal his name to the reader, but the whole cast of the series admits that it's better that he just continues to go by "Hokuto's Lackey" because they've built up their friendships and familiarities with him around it. Learning his name would be a rather jarring change to that relationship.

I'm afraid I don't know a thing about technology...
Leader of a different class. No one but Kamiyama and Hayashida recognizes that he's a machine. And if they do, they don't recognize that he's a robot.
