!!Joe Yabuki
->Voiced by: Teruhiko Aoi (Anime), Creator/KeiTomiyama (Movies), Creator/YoshitoYasuhara (Radio Dramas)

* AccidentalPervert: Once he ended up calling for Noriko by entering her room. She happened to be changing clothes, so she hit him away with a sandal.
* {{Adorkable}}: Strangely enough [[HotBlooded despite]] [[{{Jerkass}} the]] [[JapaneseDelinquents other]] [[BloodKnight tropes]] regarding his character, he has his moments. His awkwardness with the public on his first time on the ring, and his noble yet simpleminded delusions regarding the kids of the slums are good examples.
* AnimalMotifs: He is compared with bulls during his first fight with Rikiishi. [[HotBlooded It fits him like a glove.]]
* AntiHero: Joe is rude and quick to fight, but he can also be very frivolous at times. Because of his rough upbringing he is a delinquent who likes his solitude, but he later grows to appreciate his new friends and rivals.
* AwesomenessByAnalysis: Despite his brash and aggressive approach, Joe is an expert at finding counterattacks to his opponents' best techniques. His trademark Triple Cross is in fact a counter attack to a ''counter''.
* BloodKnight: His speech towards Noriko [[spoiler: when the latter tries to talk him out of boxing]] cements him as one.
* BookDumb: Grew up on the streets and has very little book learning, though he knows how to read and write. This becomes a major problem when he tries to qualify for a boxing license, and he completely flunks the theoretical portion of the test, which mostly consists of different boxing rules and techniques. He knows the answers themselves, but not their technical names.
* BreakTheHaughty: It's hard not to feel even a little bit bad for him during the Juvenile arc, when it looks like [[spoiler:Danpei has abandoned him (it's actually a SecretTestOfCharacter)]].
* BrokeYourArmPunchingOutCthulhu: [[spoiler: Calling Mendoza Cthulhu might be a bit of a stretch, but taking enough of a beating to die right after a fight with the World Champion (and not even win, [[PyrrhicVictory at least not technically]]) has got to count for something.]]
* BrokenAce: He completely falls to pieces after [[spoiler: Rikiishi's death]] and cannot hit people in the temple, but he later overcomes this.
* CharacterDevelopment: Yes, he's a jerk. Nope, he's not evil. And yup, he softens up a bit as the series advances and he finds a purpose in life.
* ChickMagnet: A minor example, and mostly in the anime where it's shown to have female fans because of his looks.
* CryCute: [[spoiler: After the welcome back party, Joe cries TearsOfJoy while in bed.]]
* {{Determinator}}: One of the earlier Shounen examples, Joe will keep standing up after falling no matter what[[spoiler: Arguably {{Deconstructed}}, since this ends up killing him]].
* DrivesLikeCrazy: Two times Joe picked up a car, two times a poor vehicle got irreparable damage. [[spoiler: The second one, however, is {{Foreshadowing}} his Punch Drunk Syndrome.]]
* FamousLastWords: [[spoiler: Before dying, he tells Youko to keep his [[TragicKeepsake boxing gloves]]. In some dubs, it's also a DyingDeclarationOfLove.]]
* GameBreakingInjury: [[spoiler: Develops advanced Punch Drunk Syndrome late in the story. He's fully aware of it yet intends to fight Mendoza anyways.]]
* [[spoiler:GoOutWithASmile: Die with no regrets because he gave all spirit in the match with Mendoza.]]
* HeroKiller: Inverted since he is a protagonist. At one point in the series nobody wants to take him on because he took down [[spoiler: Rikiishi, Wolf and by technicality, Carlos.]] Fitting for someone known as "The Grim Reaper" and "Killer Joe".
* [[spoiler:HeroicRROD: He dies from exhaustion in his final match.]]
* [[spoiler:TheHeroDies]]
* HeroicBSOD: After [[spoiler:Rikiishi's death he temporarily suffers from yips and cannot hit people in the temple .]]
* HiddenHeartOfGold: He softens up somewhat during the Juvenile arc. Also he seems to genuinely care for the [[MoralityPet kids from Slum Town]].
* HotBlooded: This is likely his biggest flaw, and constantly gets him into trouble. He cant handle even the slightest insult without attempting to fight the offender.
* HowTheMightyHaveFallen: [[spoiler: Rikiishi's death traumatizes him harder than expected; his aversion to hitting opponents in the head causes him to lose a lot of matches afterwards. This results in him deciding to fight up in the boonies, despite the fact that they ''fix'' the outcome of their matches.]]
* {{Irony}}: Despite his nickname, Joe had only won against one person that he was said to have "killed". [[spoiler: Although Rikiishi dies, he had beaten Joe in the match via KO. While Carlos receives brain damage from Joe's fight the match was officially called a draw.]]
* JapaneseDelinquents: Joe fits in the delinquent stereotype, but he's a subversion though. He starts the story as a homeless StreetUrchin and has never even been in a school. ([[BookDumb Which bites him in the ass later.]])
* JapanesePronouns: Up until Joe showed up, all shonen heroes used the non-threatening ''boku'' pronoun. He became the TropeCodifier for ''ore'' users.
* JerkAss
* MadeOfIron: You seriously cannot tank punches that could knock down a ''BULL'' without being this trope.
* MegaManning: Can and has replicated multiple of the best techniques of his opponents, such as Carlos' elbow strike during their exhibition match.[[spoiler: In the final round against Mendoza, he starts using Aoyama's defensive techniques. And in the third round he uses Rikiishi's technique for dealing with the triple cross counter. He also starts using Jose's own corkscrew punches.]]
* NiceHat: His newsboy red cap.
* NotGoodWithPeople: Summed with his [[{{BookDumb}} poor writting skills]], this is the reason he hates public signing sessions.
* ObliviousTOLove: Anime Only in regard to Noriko's crush on him. Noriko even directly hints it to ''him'' and he doesn't seem to grasp. Averted in the manga, where he's made aware, but just doesn't care.
* PeekABangs: He is known for his long bangs.
* TheReasonYouSuckSpeech: Calls out Kim Yong-bi on being completely full of himself, using his childhood trauma during the Korean War as if it's a badge to be proud of. He finishes off by saying that his actions don't make him superior, but in fact, ''inferior'' to men like Rikiishi, who didn't even have water to drink like Kin did and was ''willing'' to put himself under such conditions for the sake of having a match with a long-time friend. [[spoiler:And this is all while he is beating the hell out of Kin in the match.]]
* WeightWoe: [[spoiler: A late growth spurt pushes him far past the weight limit from a bantamweight [[note]]at 57 kilos he could possibly even qualify for lightweight, which is ''three'' classes above; even more than what Rikiishi had to do.[[/note]] This becomes a problem when he jumps the gun and challenges Kim Yong-bi, especially when the latter ''devastates'' someone who went down from the lightweight class to challenge him.]]
* WhyDidItHaveToBeSnakes: [[spoiler: After Rikiishi has passed away, Joe is afraid to hit his opponents in the head since that's what finished his rival.]]
* WorthyOpponent: Considers most of his opponents as one, and in most cases they consider him one.

!!Danpei Tange

* ZeroPercentApprovalRating: Initially. He was disbarred from the Japanese Boxing Commission because of his abusive behavior with his trainees and his alcoholic tendencies. He ends earning back his respect as a proficient trainer thanks to Joe.
* TheAlcoholic: Initially he starts drinking to forget the pain of his broken dreams. He briefly relapses after his first attempt at getting boxing licenses for Nishi and Joe fails, due to the Boxing Commission hating him, but sobers up again.
* BaldOfAwesome: Is completly bald.
* CoolOldGuy: Do not underestimate him, he is still able to give strong punches.
* EyepatchOfPower: Wear this because of losing his eye in a match.
* GamebreakingInjury: Permanent damage to his ocular nerve was the reason he stopped being a boxer. He instead started a gym afterwards.
* GratuitousEnglish: PlayedForLaughs. His nervousness when he first meets [[spoiler: Jose Mendoza, the Bantamweight World Champion]], has him awkwardly try to communicate by using random boxing terms such as "Cross-counter".
* ImpossiblyTackyClothes: Similar to the above, PlayedForLaughs. When they celebrate [[spoiler: Joe's contract with Fuji TV after becoming the pacific Champion]], Danpei comes with a pretty old fashioned suit. People are quick to lampsahde it.
-->'''Japanese reporter''': Talk about garish.
* TheLancer and TheMentor: To Joe.
* MyGreatestFailure: Became a drunkard after the boxer who he spent years training for the championship threw the fight for money. He snaps out of it shortly after meeting Joe.
* NiceHat: Occasionally wears one.
* SecretTestOfCharacter: [[spoiler: He makes it look like he has betrayed Joe for Aoyama, another prisoner. This is to get Joe to play defensively as well.]]
* TeamDad: His care for Joe grows into something comparable to a father figure, as he is often concerned for his well being above his career as a boxer. Same goes for Nishi, who lives along the two for a big chunk of the series.

!!Kanishi "Mammoth" Nishi

* AlwaysSecondBest: Joe's spot-free record after going pro causes him to develop an inferiority complex. He gets over it thanks to the Slum Town kids and [[spoiler:Noriko]].
* BetaCouple: [[spoiler:With Noriko.]]
* BigEater: This becomes a problem eventually, he cant subsist on the diet needed to keep him a middleweight.
* TheBigGuy
* TheBully / FatBastard: At first.
* CharacterDevelopment: It comes really suddenly, but he was [[ScareEmStraight scared straight]] off-screen by rumors about the juvenile prison.
* FireForgedFriends: Becomes this with Joe in prison after their... awkward first encounter.
* GameBreakingInjury: [[spoiler: Is forced to retire from the world of boxing after getting permanent damage on one of his hands.]]
* GentleGiant: This actually works AGAINST him, he's a natural heavyweight, but there are few heavyweight fighters in Asia, and he has trouble keeping his weight down to qualify for middleweight.
* HeCleansUpNicely: When he was first introduced he was a FatBastard. Come around the time after Joe's match with Kim Yong-bi and Nishi actually looks reasonably handsome.
* JapaneseDelinquents
* NiceGuy
* PermaStubble: Later on.
* ThrowTheDogABone: He gets a rude awakening once he's taken to the juvenile prison on account of not being the biggest and meanest kid he knows anymore, once he and Joe get into the pros it's shown that he's not very good at boxing and unlike Joe he can't handle the strenuous weight training that Danpei makes him go through due to his size and is ridiculed for it. However, he's shown to be very reliable to the Hayashi family market while Joe struggled to help at all, and eventually Noriko's parents trust him with the business [[spoiler: and trust him with Noriko herself.]]

!!Youko Shiraki

* AnguishedDeclarationOfLove: [[spoiler: to Joe at the end of Volume 19, in one ''hell'' of a cliffhanger.]]
* AntiVillain: She antagonises Joe mostly during the first half of the series, then organizes most of Joe's fights, and, as he puts it, toys with his fate like a demon. She is, however, a good person when it counts.
* BitchInSheepsClothing: One of the first things Joe calls her out on is the hypocrisy of her "charity" at Juvenile Prison. Even when she(mostly) grows out of it, her schemes can be underhanded[[spoiler: (such as to trick Takigawa Shuuhei into fighting Harimao to test the later's abilities, with little care for Shuuhei's well being)]]
* CoolShades
* EveryoneCanSeeIt: Pretty much everyone at Danpei's Gym thinks this regarding her and Joe. [[spoiler: They're proven right in Volume 19.]]
* HeroicBSOD:[[spoiler: Just like Joe, she has one when Rikiishi dies.]] Unlike him, she recovers quickly.
* GreenEyedMonster: DiscussedTrope. Sachi seems to think this about her when she first met Noriko. Then again Sachi has a PrecociousCrush on Joe, and it was clear she was just projecting herself.
* IconicOutfit: Her white and red dress.
* {{Irony}}: Despite being the one that ''always'' leaves boxing matches whenever they get ugly, and that she cares a great deal for Joe's medical condition, [[spoiler: in Joe's fight against Mendoza, she, is the ''only'' one who encourages Joe to fight to the bitter end and leave no regrets in the ring. This is despite the fact that Joe's punch-drunk syndrome is so bad at this point that ''he can't even see out of one of his eyes'']].
* LoveEpiphany: [[spoiler: It's not until the matchup between Joe and Mendoza finally becomes a reality that she realizes that the only reason she sticks her nose into Joe's business is because she loves him.]]
* MyGodWhatHaveIDone: She's plagued with guilt after Carlos hints that he might not have been fighting seriously in his exhibition match against Joe. She's noticeably not her calm and aloof self during the real match between them at Korakuen Hall, fearing that she may have set him up to be killed in the ring.
** All the bloodshed during the match between Carlos and Joe at Korakuen Hall becomes too much for her at one point.
* NonIdleRich
* TheOjou: She's a calm, soft-spoken girl from a rich family.
* SilkHidingSteel: Noted, and respected for being a big-time promoter in a sport considered to be strictly for men. There's mention of another female promoter having broken the gender barrier previously, but she never appears.
* StayInTheKitchen: Joe is not very fond of her presence in the boxing world. It should however, be noted that Joe is the ''only'' one who objects to it throughout the series. While other people ''were'' skeptical at first, they pay no attention to her gender once she shows she's more than capable about being a promoter.
* TenderTears: When she [[spoiler: begs Joe to cancel the match against Mendoza once it's revealed that he has punch-drunk syndrome.]]
* [[spoiler:TragicKeepsake: The boxing gloves she received from Joe in his last fight.]]
* [[{{Tsundere}} Tsundere]]: Her thoughts on Joe clearly are of more concern she's willing to admit. Lampshaded by Rikiishi.
-->'''Rikiishi''': Why do you sent those bouquet of flowers to him?
-->'''Youko''':(...)You want to fight Yabuki no matter what, don't you?(...)That's why I sent those flowers. Think of it as funeral flowers
-->'''Rikiishi(smiling)''': A little too flashy for a funeral if you ask me.
-->'''Youko''':That's enough.
* WeWantOurJerkBack: Of all people, she is the one that helps to convince Joe to get back into boxing after [[spoiler: he accidentally kills Rikiishi]]. Though Joe fires back at her by saying that she's just toying with him, she makes a good point: [[spoiler:Rikiishi definitely wouldn't have wanted him to stop boxing]].
* WhatTheHellHero: Called out by Joe when she tries to leave during his match against Rikiishi in juvenile prison, with Joe pointing out that since she's the one that allowed it to happen, she should stick through it. This gets a CallBack during the match between Joe and Carlos, as she remembers that instance when she gets overwhelmed by how ugly the match between Joe and Carlos gets and convinces herself to stay.
** Gets another callback [[spoiler: when she leaves during Joe's fight with Mendoza, actually driving away, only to come back once she once again remembers Joe's match against Rikiishi.]]

!!Tooru Rikiishi
->Voiced by: Shūsei Nakamura (Anime), Creator/HideyukiHori (Videogames)

* TheAce: To an almost ridiculous extent, he outpaces everyone, even Joe, by a mile.
* [[spoiler:CasualtyInTheRing]]
* CharlesAtlasSuperPower: Beating down ''pigs and bulls'' with your bare fists isn't something the average boxer, let alone human, is able to do
* CulturedBadass: A minor case, but outside of the ring he's outright gentlemanly.
* {{Determinator}}: Especially notable when he has to lose weight. [[spoiler: This ends up being what kills him.]]
* DiscOneFinalBoss: A ''lot'' of hype is built up between the professional fight between him and Joe, both being regarded as up and coming talents. [[spoiler: The match does not disappoint, but his untimely death afterwards ''does''.]]
* EstablishingCharacterMoment: His first action onscreen? Punching down ''pigs'' to stop Joe's escapade from Juvies, and beating Joe in a single punch when he tries to fight him.
* FaceOfAThug: Moreso after his weight loss. He's still oddly handsome though.
* {{Foil}}: To Joe, obviously. While both are delinquents who take up boxing, Rikiishi is good-natured and looked up to by rest of the delinquents, while Joe is a {{Jerkass}} who is hated by many at first.
** Also, Riikishi is sponsored and essentially taken care of by Shiraki Gym, a top class facility run by a wealthy family. Joe is sponsored by Danpei Tange, a trainer who's fallen out of graces with most of the boxing world and has no money to his name.
* IconicItem: His wheat stalk.
* JapaneseDelinquents: Even though it's eventually [[CulturedBadass subverted]], Rikiishi is introduced in the Juvies after all.
* LanternJawOfJustice
* LightningBruiser: Is able to win a fight using only uppercuts, despite them being easily the slowest punch in boxing(Joe had to train specially to keep distance because his uppercuts were ''that'' fast). On top of that he's strong enough he can punch down ''BULLS''.
* TheOnlyOneAllowedToDefeatYou: Gives a downed Joe words of encouragement during his fight against Wolf Kanagushi for this very reason.
* RatedMForManly: To this day, Rikiishi is one of the best examples of the positive side of classic masculinity in Japanese Media
* TheRival: To Joe.
* TheStoic: In strong contrast to Joe.
* VitriolicBestBuds: On the day of his release from prison, a guard muses that he and Joe are, in a sense, each other's closest friend. Joe himself realizes this after [[spoiler: Rikiishi's death. It almost destroys him]]
* WeightWoe: PlayedForDrama. Since he's a Featherweight and Joe's a Bantamweight, he goes through great strains to keep himself two weight classes under his normal size in order for the two to have their fight. This results in the Shiraki Gym resorting to methods such as locking him behind a chained door (which he manages to ''break down'') and tying up all the pipes in the facility. [[spoiler: This hellish method also leads to his undoing as the effects from the extreme weight loss as well as the hard blow to the temple from Joe cause his death.]]
* WorthyOpponent: Spends the beginning of his time in the story as a source of motivation for Joe to be a better boxer, and later on, it's revealed that he views Joe in the same way. [[spoiler: All the more tragic when he dies.]]

!!Mikinosuke Shiraki

* NonIdleRich: Youko's grandpa, Rikishi's boss, and the owner of the Shiraki Gym.
* {{Determinator}}: He is described as this by Yoko, [[InformedAttribute but we don't actually see it.]] Could be a case of HowTheMightyHaveFallen, considering that after [[spoiler: Rikiishi death]], he wanted to close his gym, unlike his daughter who was still determined to keep the business afloat.
-->'''Brutal? That's a weird way to view it. The secret of my grandfather Mikinosuke Shiraki's success in the world of business, is because when he was still young, [[{{Determinator}} he was always getting back up every time he was knocked down in his boxing matches]], and thanks to that, the spirit was planted deeply into his heart."''

!!Wolf Kanagushi

* GameBreakingInjury: [[spoiler: Joe's triple cross-counter does irreparable damage to his jaw.]]
* HeelFaceTurn: Takes a ''long'' time for it to happen, but [[spoiler: at the end of the manga he supports Joe for his last match, actively cheering for him in the stands.]]
* HeroicBSOD: Is implied to go through one after receiving Joe's Cross Counter, obsessing over it. He snaps out of it to develop a counter strategy, though
* HoistByHisOwnPetard: [[spoiler: Wolf beating the kids up lets Joe figure out his strategy because he used the same one while hitting them, due to being in the middle of training]]
* KavorkaMan: Anime-Only. He's engaged ''[[{{Jerkass}} somehow]]''.
* NotSoDifferent: With Joe. Both are cross-counter specialists and have very short tempers.
* [[spoiler:WouldHurtAChild: Beats up Joe's kid friends after he catches them spying on his training. And we mean BEAT UP, as in, had to go to the hospital]]
* {{Yakuza}}: Becomes one for a short period of time. [[spoiler: It ends once he finds out the hard way why a person with a glass jaw doesn't make for a good fighter.]]

!!Jun Shioya

!!Jiro Shioya

!!Harry Robert

* AntiVillain: Like Carlos, he has little ill-will towards his fighter's opponents and is considered a good guy.
* {{Eagleland}}: Type 1.
* LikeASonToMe: Has this relationship with Carlos, as he helped raise him from the slums of Venezuela
* OhCrap: He too is stunned when Joe shows that he's no pushover for Carlos to play around with.
* [[OnlyKnownByTheirNickname Only Known By Their Last Name]]: He is rarely, if ever, called "Harry".
* PhenotypeStereotype: In the anime.

!!Joe's kid friends (Sachi, Tarou, Kinoko, Chibi, Churumatsu, Tonkichi)

* ButtMonkey: Kinoko is usually the target of Sachi's sandals. Most of the time he's asking for it, though.
* NiceShoes: Sachi has the unfortunate habit of smacking anyone that pisses her off with her geta sandals. It usually is Kinoko
* MoralityPet: Joe cares for them quite a bit.
* PrecociousCrush: Sachi has one on Joe. It's always PlayedForLaughs.
* ShipperOnDeck: Kinoko initially seems to root for [[spoiler:Joe and Noriko.]], but he and the rest end rooting for [[spoiler:Nishi and Noriko.]]
* StraightMan: Taro is usually the most level headed of the group. Relatively at least.

!!Noriko Hayashi

* {{Foil}}: To Youko. One is a lady from a Rich Family often having a stern demeanor, the other one being the daughter of a modest marriage with a small store in the slums with a very sweet demeanor, both trying to help Joe based on their own viewpoints.[[spoiler: Both also are in love with him]]
* GirlNextDoor
* GirlishPigtails
* HopelessSuitor: It's very clear that she likes Joe, even to the point where people like Danpei notice. However, Joe's married to the world of boxing. Plus, her attempt to talk Joe into retirement makes it clear that nothing's gonna happen between them.
* RomanticFalseLead: Inverted as Joe is this to her. [[spoiler: She gets together with Nishi.]]
* [[spoiler:StepfordSmiler: Has heavy shades of this after she gave up on Joe. Not because of their relationship(even if it's implied she still ''does'' have lingering feelings for him), but because of Joe's health seems to be compromised on his career. Even the day of her ''wedding'' she seems afflicted.]]
** [[spoiler: It's even worse because [[{{DownerEnding}} she's proven right at the end]].]]
* SheCleansUpNicely: While she was never really that homely, she looks positively stunning once she perms her hair and gets rid of the drab clothing.

!!Keshichi Hayaka

!!Tamao Hayashi

!!Kim Yong-bi

* AfraidOfBlood: [[spoiler: Can't stand the sight of blood due to mistakenly killing his father.]]
* TheDreaded: To begin with, his nickname was "The Boxing Computer" because of the perfection of his technique. Had a perfect win ''and'' KO record, and [[{{AdaptationExpansion}} (Anime Only)]] had killed two of his opponents before fighting Joe. He's one of the few contenders Tange decided to actively ''avoid'' have Joe fighting.
* {{Foil}}: To Joe. Kim's boxing style is methodical, while Joe's style is flashy and often unpredictable.
** He also acts as a foil to Joe's other major opponents. Riikiishi and Carlos may have had radically different personalities outside of the ring, but once in the ring they fought with passion and treated the ring like if it were a life and death situation. Kim is stoic and dispassionate both in the ring and out of it, viewing boxing as "just a game".
* GeniusBruiser: His boxing style is compared to that of a trained physician, as if he's dissecting them methodically.
* HarmfulToMinors: [[spoiler: During the Korean War, he got to watch his mother be killed by a firebomb and the body burn to a crisp in front of him. He was around the same age as the current Slum Town kids when this happened. And that's not even describing what happened to his dad...]]
* HoistByHisOwnPetard: [[spoiler: His phobia of blood makes him scream like a madman...and nothing else. Once one of his punches cuts Joe, he just stands there screaming, allowing Joe to shut him up for good by knocking him over the ropes.]]
* NotSoStoic: [[spoiler: Has a panic attack during Joe's NoHoldsBarredBeatdown of Danpei after he sees the latter on the ground bleeding profusely. His freak out manages to frighten everyone in the room, including Joe.]]
** [[spoiler: Also loses his cool while Joe calls him out on his assholish behavior during their match, swinging wildly and unpredictably which allows Joe to hit him with ease.]]
* OutDamnedSpot: In a similar vein to the TropeNamer, he causes a stir during his stay at the Asian Boxing Club by washing his hands and mumbling about them being bloody. All night, in fact. Quoth his trainer.
--->''He sees blood on his hands that he can't wash away no matter how hard he tries.''
* SelfMadeOrphan:[[spoiler: After days of starving in the War, he found an ill man covered in mud with rations. When he tried to steal them, said man defended them with all he had, so Kim desperately killed him crushing his head with a rock. Turns out [[{{Irony}}it was his father trying to reach him and her mother to feed them]], but neither recognized each other, one because of the mud and the other because his features were changed out of the starvation.]]
* SpellMyNameWithAnS: His name has been given as Kim Yong-pi, Kim Yong-bi and even Kin Ryuhi.
* TheReasonYouSuckSpeech: Gives one to Joe, mocking him for not being able to control his weight like he can and is disgusted by how he builds himself up like a hungry champion, while he experienced ''real'' hunger and hardship starving in the streets of South Korea during the Korean War. [[spoiler: Joe returns the favor during their match.]]
* TraumaticSuperpowerAwakening: [[spoiler: A particularly dark example(and subversion), he's unable to gain any weight out of a mental block regarding eating, since he mistakenly killed his father for food. The "upside" to this is that it keeps him consistently in the bantamweight division]]

* AxCrazy: Attacks people without abandon, regardless of if he's in a boxing match or not, and with little to no provocation whatsoever.
* CombatPragmatist: Comes with his um, different kind of boxing style.
* ForeignWrestlingHeel: Portrayed as this. When he comes out to fight, literally nobody cheers for him. Notable in that even jerkasses like Kim Yong-bi had fans in the stands; whenever Harimao's involved in a fight everyone wants to see him get beaten.
* FreakOut: [[spoiler: starts headbutting and ''biting'' Joe after getting knocked down one too many times.]]
* HairTriggerTemper: Of course that would imply that he ''needs'' something to get angry at.
* InsaneTrollLogic[=/=]LoopholeAbuse: ''Lives'' off of it. Complain about him standing on the ropes? The rules state that he can't step outside of them but there's nothing about them that says he can't step ''on'' them. Complain about him jumping up in the air? Ref states that there's no rule against that either. Basically, whenever the crowd complains about his antics in the ring, expect them to be met with the ref saying that there AintNoRule.
* MeaningfulName[=/=]NamesToRunAwayFromReallyFast: Harimao means 'Tiger' in Malay. Given his style it's not hard to see why.
* NeverLearnedToRead
* OnlyKnownByTheirNickname: He originally went by his real name, which was much longer and harder to pronounce. After a certain incident they just called him Harimao.
* RaisedByWolves: Was raised in the deepest parts of a Malaysian jungle by beasts of the wild before being found by villagers.
* ShadowArchetype: To Joe. He's basically an extreme version of what Joe would have been if Danpei hadn't found him.
* TheUnintelligible: Sort of. It's only made clear that he can't speak Japanese, implying that he can speak his native tongue. But with his roars and grunts you really have to wonder.
* TrademarkFavoriteFood: Chocolate is the ''only'' thing that makes Harimao settle down. Even then it sometimes fails.
* UnskilledButStrong: Hoo boy. It's debatable if what he practices is even ''boxing''.
* VillainousBreakdown: [[spoiler: Once Joe counters his corkscrew backflip punch with an even wilder technique he becomes ''terrified'', realizing that he has met his match in Joe. As the announcer puts it, to him Joe is "a foe even wilder than himself existing in civilization".]]
* WildChild: Quickly proves that Shiraki was not joking when she said she had found an animal of a boxer.

!!Jose Mendoza

* TheAce: Strongly established [[spoiler: then subverted once he fights Joe.]]
* AchillesHeel[=/=]FatalFlaw: A very big one, as Joe points out in their match.[[spoiler: Jose is great at dishing out damage, but not good at ''taking'' it.]]
* BerserkButton: Joe is warned by the Hawaiian press that Mendoza ''hates'' loud-mouthed people and that they are one of the few things that make him upset. Joe, being Joe, only learns this fact the hard way when [[spoiler: he mouths off to Mendoza and is dropped by a single punch.]]
* CombatPragmatist: [[spoiler: Realizes that Joe can't see out of the left side of his eye during their match, no doubt due to injury taking a toll on his body. He doesn't hesitate to exploit that.]]
* CurbstompBattle: His fight against Carlos Rivera turns out like this.
* DefeatingTheUndefeatable: He is introduced in the series via knocking out Carlos in Round ''1''. And he's not afraid to show off the fact that he is this; when the series actually shows one of his fights, he allows his opponent, a guy nicknamed "The Hawaiian Bull", to hit him at point-blank range in order to show off that nobody's punches can leave a mark on him before effortlessly [=KOing=] his opponent. [[spoiler: But later, we find out that he's not quite this trope.]]
* EarlyBirdCameo: He is mentioned by Danpei during the Prison Arc.
* EstablishingCharacterMoment: When he first appears in the series proper he grabs Joe's shoulders and wishing him good luck. This was enough to leave ''bruises'' on Joe. That's how powerful he was.
* FreakOut: [[spoiler: Not even Mendoza can keep his composure against Joe. He loses all inhibitions and goes crazy when no matter what he throws at Joe, ''Joe just won't go down''.]]
* [[spoiler: GlassCannon]]: Turns out to be one
* HappilyMarried
* HeroAntagonist
* JerkWithAHeartOfGold: Despite treating Joe like crap (though to be fair like every other situation where he pisses someone off, Joe was asking for it), Mendoza respects him a great deal. That's why he's disappointed in their fight when Joe comes out with only [[AttackAttackAttack one goal]] in mind.
* LockedIntoStrangeness: [[spoiler: His hair turns white after the fatal fight with Joe.]]
* OhCrap: [[spoiler: When Joe finds out that his display against the Hawaiian Bull was nothing more than an elaborate ''bluff'': by recreating the situation in their match, Joe shows that holding a boxer's shoulder greatly reduces a boxer's upper body strength.]]
* PoliticallyIncorrectHero: Calls Joe names such as "yellow brute" and "yellow sheep", but for the most part is respectful to the other Japanese characters in the story.
* PyrrhicVictory: [[spoiler: Beats Joe, but at the cost of his youth.]]
* TerseTalker
* [[VillainousBreakdown Heroic Antagonist Breakdown]]: [[spoiler: Starts getting very philosophical (and not in the good kind) when Joe takes enough damage to cripple, if not outright kill someone --but Joe just keeps coming back off the mat no matter ''how'' many times he knocks him down.]]
-->[[spoiler: Joe Yabuki...must have already died long ago...but then...''who'' am I fighting with on the ring...? Am I fighting with his phantom...? Or am I trapped in a nightmare...?]]
* WorthyOpponent: Considers Joe as one; in fact he considers him to be a better man than he is [[spoiler: when despite taking inhumane amounts of damage, Joe continues to fight. Mendoza admits that at that point he would give up, thinking more about returning home to his family]].
* [[WhyWontYouDie Why Won't You Stay Down]]: Joe refusing to go down confuses him ''greatly''.

!!Carlos Rivera

->Voiced by: Creator/RyuseiNakao (Second series)
* AntiVillain: He's very laid-back and friendly outside the ring. When he took some time off from boxing one day he spends most of it singing and hanging out with the Slum Town Kids.
* BewareTheNiceOnes[=/=]BewareTheSillyOnes: Has a tendency to play around with opponents to make the matches more exciting, luring them into a false sense of confidence that they can beat him. Then, he [[LetsGetDangerous shows them]] ''why'' he's called the "Venezuelan Terror".
** Actually enforced in-story by his trainer Harry Robert. When asked by the media, Robert says that the reason Carlos plays around with his opponents is because when he gets serious, no other gym (understandably) wants their boxers to challenge him.
* CameBackWrong: [[spoiler: When he returns after being "retired" by Mendoza, he is pretty much a shell of his former self.]]
* CombatPragmatist: Carlos isn't afraid of committing fouls if the situation demands it. One of his trademark techniques involve slipping an elbow strike after throwing a hook. Joe is one of the few ones to catch on this.
* {{Foreshadowing}}:
** [[spoiler: On his departure from Japan, he suddenly falls down while saying his goodbyes to the Japanese people.]] [[spoiler: After his disastrous fight against Jose Mendoza, Robert reveals to the press that Carlos was having difficulty doing simple tasks such as ascending the stairs, something that usually happens to boxers that suffer from Punch-Drunk Syndrome.]]
** At the end of the 4th round in his match against Joe, Robert talks to him, only for him to be ignored. [[spoiler: Then he starts to blatantly fight wild and dirty until he's knocked down by Joe, who also starts to fight dirty. His shocked expression when Joe knocks him down indicates that Carlos may have not been completely there when committing all of those fouls, signifying the start of his brain damage.]]
* FreakOut: [[spoiler: Pretty much loses his shit and starts to fight dirty against Joe after the fourth round in their bout at Korakuen Hall, going from simple fouls such as elbow strikes and head-butts to attempting to attack an ''already downed'' Joe, '''knocking the referee out of his way''' to do so.]]
* GameBreakingInjury: [[spoiler:Fights Jose and pays the price through acquiring severe brain damage.]]
* JerkWithAHeartOfGold: Regardless of necessary reasons why, his method of baiting opponents into getting the living daylights beaten out of them tend to rub some readers the wrong way. Apart from that he shows no jerkish tendencies and for the most part, is a good guy.
* LetsGetDangerous: As noted above. He may be a charismatic playboy but don't ever think that his ranking in the world is for show.
* OhCrap: In his bout against Joe at Korakuen Hall.
** When at the beginning of the match, he realizes that Joe isn't the same person he fought during their spar and exhibition match
** When [[spoiler: Joe manages to make it to his feet and continue fighting after Carlos brutally counters the rope trick that Joe used to surprise him in their exhibition match.]]
** Finally, when Joe [[spoiler: knocks him down even ''after'' he's countered Joe's rope techniques]]. It completely changes the complexion of the fight as Carlos becomes noticeably sloppier in his movements.
* PutOnABus: [[spoiler: After his disastrous fight against Mendoza he retires and was seen wandering the streets of Venezuela.]]

!!Goromaki Gondo
* AntiVillain: A very benevolent yakuza even before Joe befriends him.
* AwesomenessByAnalysis: He caught on Joe's true strength without actually knowing his name(Joe was already a renowned boxer after [[spoiler: Rikiishi's death]]).
* BerserkButton: A minor one, but dislikes people that lack the will to fight.
* CombatPragmatist: He doesn't hesitate in [[spoiler:attacking Wolf Kanagushi's glass jaw first]].
* CurbstompBattle: His introduction has him in both ends. [[spoiler:He beats Wolf Kanagushi in no time, only to be beaten to a pulp by an angered Joe]].
* DefeatMeansFriendship: When he [[spoiler:calls Wolf a disgrace of a person after beating him up]], he is in turn beaten up by an enraged Joe.
* HeelFaceTurn
* NeighbourhoodFriendlyGangsters: Post HeelFaceTurn he shows up to help Joe prepare for his fight against Harimao.
* RuggedScar: Has a scar in the right cheek to show he's a tough one, [[{{OffModel}} even if it's not always drawn]].

!!Tiger Oozaki
* HairTriggerTemper: While Joe is a {{Jerkass}} and was intentionally trying to provoke him, it certainly didn't take much to rile him up before the match.
* SacrificialLion: [[spoiler: Is the first Japanese boxer unfortunate enough to taste Carlos' real strength.]]
* UnwittingInstigatorOfDoom: Twice.
** First time,[[spoiler: his actions lay out a blueprint for many of the other boxers on how to beat a reinvigorated Joe, and the losses that Joe picks up destroys nearly all of his reputation in the boxing world.]]
** Second time, [[spoiler: his overconfidence brings out the ''real'' Carlos in their match and he's literally beaten before he realizes it. Everyone else that was willing to fight Carlos under the thought that he wasn't very good realizes that they are completely screwed because they can't back out. Carlos was more than happy to prove them correct, brutalizing all of them.]]
