[[folder: Tatewaki Kuno (九能 帯刀)]]
->Voiced by: Creator/HirotakaSuzuoki (JP), Ted Cole (EN), Gabriel Gama (LA, TV series), José Carlos Moreno (LA, one episode), Óscar Flores (LA, Movies and OVAS), Eyas Abughazala (AR)

Originally the greatest champion of Furinkan High, until Ranma Saotome arrived. He does remain its greatest pervert, though. A pompous, bombastic scion of a noble house, his father is the principal of Furinkan and this, coupled with his skill, makes him someone of importance in school. Caught up in his own ego and almost delusional obsessions with the samurai, he blatantly lusts after Akane Tendo -- and doesn't lose any interest even when he finds himself also smitten with a mysterious "Pigtailed Girl", making no secret that his ultimate desire/intention is to have them both as his wives. That neither of them is even attracted to him, never mind happy with the idea, is something that doesn't register.

* AbhorrentAdmirer: To both Ranma (female form) and Akane. Despite both of them not only explicitly pointing out how little respect they have for him and his "affection" and have defended themselves with physical force against his sexual advances, he remains completely clueless and continues to pursue both of them.
* AdaptationDyeJob: Black-haired in the manga, brown-haired in the anime
* AwLookTheyReallyDoLoveEachOther: On rare occasions, shows a sibling variant for his sister.
* BadassNormal: The guy can shatter stone statues with the air pressure from his sword strikes! Basically, he is still superhuman.
* TheBully: The primary reason he and Ranma almost constantly lock horns. Kuno ''loves'' to throw his weight around, and brutalize people into bending to his will. Ranma not only refuses to bend the knee, but, being a BullyHunter, comes down on Kuno like a ton of bricks every time he sees the lout try to terrorize someone else. [[IRejectYourReality Of course, Kuno utterly fails to comprehend that people don't like it when he bosses them around, and think Ranma is the source of their unease.]]
* ButtMonkey: His track record would point in this direction... though oddly, Kuno ''himself'' seems rather [[SelectiveObliviousness oblivious]] to it.
* CantCatchUp: Presumably because he's so arrogant that, given how he frequently "explains" away his loses to Ranma and co, he doesn't believe he ''needs'' to improve his skills. Subverted when he loses his memory and learns a technique that turns him into more than a match for Ranma. The problem is that he can only use it with a visual trigger (watermelons). So, since there usually aren't any around he stays much the same after this incident.
** For extra subversion, the training was never ''intended'' to boost his fighting skills: it was TrainingFromHell so he could become a master of the SmashingWatermelons game. He learned the move to be able to impress girls whenever he went to the beach.
* TheCasanova: Thinks of himself as one, and might have actually had this status before Ranma arrived at his school. However the girls he actively pursues both despise him and reciprocate none of his affection. So by for the majority of the series he believes he's womanising Akane and the "pig tailed girl", whereas in reality neither of them give a crap about him or his "cheating" on them.
* ChivalrousPervert: Is this PlayedForLaughs. How far he falls onto the chivalrous or pervert side, usually depends on RuleOfFunny. Once when a girl offered to allow Kuno to do anything to her, Kuno's response was just to [[FaceDoodling doodle on her face]].
* CongruentMemory: See CantCatchUp. Don't come near him if you're carrying [[BerserkButton watermelons]], unless you want him to turn into human-shaped whirlwind of RazorWind that even Ranma can't defeat. He gets over it by the end of the story arc and it's not mentioned again in the manga, though an anime {{filler}} episode shows he does still have it, and may even have more control over it... Of course, he doesn't think of its combat potential even then; it's a way to impress girls.
* TheDitz: Several instances have emphasized that Kuno isn't very bright. Despite the glaringly obvious signs, he is ''never'' able to figure out that the "pig-tailed girl" he loves and his [[TheRival rival]] Ranma Saotome are one and the same. Also during the Moxibustion Arc, he interprets the "Ranma is weak" fliers that Happōsai dropped as Ranma trying to find an excuse for why Kuno beat him.
* DitzyGenius: He does very well in school and is well versed in poetry despite his cluelessness.
* EasyAmnesia: Caused by the watermelon training incident mentioned above.
* {{Expy}}: Takes some inspiration from Shuutaro Mendo from ''Manga/UruseiYatsura'', being a buffoonish rival to the main character. The anime extends this further by also making him filthy rich.
* FacelessGoons: An identical look-alike to Kuno in an anime {{Filler}} episode delivered the page quote to his group of {{Highly Visible Ninja}}s.
* TheFightingNarcissist: He believes his swordsmanship makes him the best fighter in the world, which he's always itching to show off on some poor sod, for little to no reason. He, furthermore, doesn't beleve he ''can'' improve because he's already "perfected it." For the finale, he thinks that running around and beating up on random people with his bamboo sword will make every girl who sees him in action, fall madly in love with him, especially if said girl happens to be someone that showed interest in Ranma first, such as Akane and "pig tailed girl." Not only are his romantic obsessions wholly unhealthy, for all involved, he utterly refuses to believe he can be wrong about this.
* FriendlyEnemy: Particularly in the anime, he is sometimes treated as a clumsy friend of the cast.
* GlassCannon: He is strong enough to shatter stone with the air-pressure from his strikes, but can be floored with a single punch.
* HandsomeLech: Lusts after Akane and "The Pigtailed Girl", including groping them and grabbing them whenever he can, but is actually fairly attractive to other girls, due to being, good-looking, athletic, aristocratic, rich (in the anime at least) and capable of speaking/acting in a flowery, poetic fashion. The anime plays this up by having Kuno be willing to try chasing after other women who he notices as attractive, including Ukyo, Nabiki, Azusa Shiratori and Miss Hinako. However, he never gives up on chasing Akane and Ranma's female form while doing so (in fact, the Nabiki episode goes so wrong partially because he declares to the whole school he's going to marry Nabiki and keep his "other loves" as his mistresses) and goes right back to chasing them wholeheartedly after his attempted diversions come to naught.
* HilariouslyAbusiveChildhood: His dad berated him in flashbacks, left him to go to Hawaii, and [[ArsonMurderAndJaywalking shaved his head]].
* IgnorantOfHisOwnIgnorance: As a result of reaching his High School Senior year, easily defeating any and every challenger, or person who happened to catch his eye when he was in the mood to beat someone up, he's let himself believe he's the best fighter the world has ever seen, utterly refusing to admit his near constant defeat at Ranma's hands is the result of anything but "sorcery." What's worse is that Ranma is clearly not even the strongest martial artist in Nerima alone, let alone the world.
* IronButtMonkey: Kuno takes a lot of abuse and gets hurt easily but he has a high recovery rate most of the time. Lampshaded in the episode "Kuno acting Principal" in which Kuno gets kicked out of a window and instantly pops up two seconds later to Ranma's surprise.
* IRejectYourReality: His beliefs that he is the greatest warrior around (comparatively, he's probably one of the weakest fighters in the cast), that Akane Tendo and "the pig-tailed girl" love him immensely (he's probably the one to blame for Akane's [[DoesNotLikeMen dislike of men]] and Ranma would hate him even if he didn't tried to get fresh with his girl form constantly), that Ranma is a "playboy" who has some sort of switching with the Pigtailed Girl, and that every time he's won against Kuno has been a "fluke" that involved Ranma using some sort of cheat (Ranma pulling an OffhandBackhand on Kuno it just ''cannot'' be called a CurbStompBattle even charitably) while dealing with the issues of the episode (like the latest argument with Akane) is one of the show's [[RunningGag Running Gags]]), and that this "sorcery" is the reason the "pig-tailed girl" is under Ranma's thrall and that by defeating Ranma Kuno will have the Girl [[RescueRomance falling at his feet]] (Ranma has tried to explain a few times and has even changed in front of Kuno repeatedly-Kuno doesn't believes that there's a curse involved). There is ''absolutely'' no way to change his mind ''at all''.
* {{Jerkass}}: He's arrogant, believing himself to be the best fighter of all, brags and flaunts his power to all who will listen, and treats his manservant like crap.
* JerkJock: In a sense; during the Hiryu Shoten Ha arc, he has no qualms at all about attacking Ranma upon finding flyers that announced Ranma's weakened state, even though he had already confirmed they were true by beating up Ranma earlier that morning. On the other hand, Kuno's ego meant that he assumed the flyers were lying and he had won "fair and square", so he was attacking Ranma to try and prove that Ranma wasn't weak at all. Didn't stop him from continuing to pummel Ranma, or attacking him twice during and after the final battle of the arc, though.
* KendoTeamCaptain: Is captain of the School's Kendo club.
* KidSamurai: An excellent example of the comedic/antagonistic variant. Barely samurai in name only, though...
* LethalJokeCharacter: Compared to Ranma, Ryoga, and Mousse, he's almost a joke. However, he's very deadly against normal humans and can fight evenly against Akane or his sister, who in turn has been able to keep up in free-for-alls against Ukyo and Shampoo.
** Kuno actually has the potential to be ''[[CrouchingMoronHiddenBadass freaking scary]]'' if you consider that he was throwing {{Sword Beam}}s ''long'' before ki was introduced as a viable power-up, meaning that he's making RazorWind projectiles ''[[BadassNormal by sheer muscle power]]''. There's no telling just how terrifying he'd be if he ever got some dedicated training that didn't depend on having watermelons around.
* LetsGetDangerous: Usually a pathetic [[JokeCharacter comic relief]] character, he actually becomes a very potent threat to Ranma when he undergoes conditioning training using watermelons.
* LordErrorProne: Considers himself a samurai, and technically is one, but is a bumbling fool blinded by his own ego and considered by most as an arrogant moron.
* LovesMyAlterEgo: He loves "the pigtailed girl" completely unaware that she is Ranma's female side.
* MadLove: Kuno is after both Akane and "the pigtailed girl". Neither rain, nor snow, nor [[MegatonPunch repeated knocks into the stratosphere]] [[AmusingInjuries or blows to the head]] will deter him.
* MadeOfIron: For someone so out of the league of other characters, he is able to take an immense amount of punishment while walking away with minimal injury. He's constantly battered and bruised by Ranma and Akane, but shows up soon after no worse for wear.
* MarryThemAll: When first confronted in public with both Akane and Ranma's female form at the same time, he agonized over choosing between them for several moments, then finally tried to {{Glomp}} them both with a passionate cry of "I must have them both!" This phrase is something of his unofficial CatchPhrase [[MemeticMutation amongst the fans]].
* NeverMyFault: Kuno never loses! If he does, it's not his fault! His opponent must have cheated! That's the only explanation!
* TheNicknamer: Even after learning her name, he refers to Ranma as "The pig-tailed girl" (though this could be because he doesn't want to associate her with his hated rival). He also refers to himself as "The Blue Thunder of Furinkan High", even though nobody else does. During his first appearance, it is implied that he has given himself a long string of self-aggrandizing titles and nicknames, of which "The Blue Thunder" is only the most recent (and apparently the last); before Ranma showed up, he had been calling himself "The Shooting Star".
* NotSoDifferent: Though loathe to admit it, he ''really'' takes after his father. Both men are horrible petty tyrants who are utterly delusional, and believe they're loved, unconditionally, for instilling a ReignOfTerror, and utterly fail to comprehend how they can possibly be wrong, about anything.
* OvershadowedByAwesome: Once Ranma and his ''real'' rivals, and maybe even his other fiancées, showed up, Tatewaki became a second-string threat.
* PosterGalleryBedroom: Has dozens, if not hundreds, of photos of Ranma's female form and Akane Tendo scattered around his room, both in dozens of photo albums and as blown up posters on his walls. In the anime, at least, he even as a poster-sized portrait of each girl hanging in the kendo club, in front of his favorite meditation spot.
* PrinceCharmingWannabe: He believes himself to be the hottest and most irresistible guy in the world. Both of the girls he obsesses over can't stand him and clobber him every chance they get.
* PromotionToParent: Had to raise his sister Kodachi alone for quite a bit. A whole episode in the anime is centered about his and the Principal fighting out for the right to be at her parent-teacher conference, which is considered as Kuno's CrowningMomentOfAwesome.
* SelectiveObliviousness: He has had "the pigtailed girl" change into Ranma ''right in his arms'', and ''back again'', and he comes up with outlandish explanations instead of acknowledging they're the same person.
* SelfServingMemory: Once when Tatewaki had amnesia, he came up with a romantic history between him and Girl Ranma.
* SempaiKohai: He always [[strike:insists]] demands that the younger students address him as "Kuno-sempai" ("Upperclassman Kuno" in the English translations).
* ShelteredAristocrat: At many times, he's rather ignorant of how the world works.
* ShipTease: With Nabiki in the anime. Besides the time he thought he was destined to wed her, she also saved him in ''Nihao My Concubine'', they got through the Cursed Tunnel of Love, and she immediately shows concern for him when he gets poisoned in "Let's All Go to the Mushroom Temple."
* ShockAndAwe: His love of DramaticThunder is upgraded to Thunder control in many of the video games.
* SmallNameBigEgo: Despite how frequently he [[CurbStompBattle gets the floor wiped with his ass]] and the blatant disdain both Akane and "the pigtailed girl" have for him, Kuno insists he is the greatest martial artist around and that his two "love interests" are actually fighting each other for the right to be his one and only.
* StalkerWithACrush: An exemplary example, and perhaps the earliest one in the series. He frequently pops up out of nowhere to try and hug/grope Akane or "the pigtailed girl".
* TraumaticHaircut: His father shaved his head against his will.
* VitriolicBestBuds: Hangs around with Nabiki in class, mostly so he can brag to her, and she can make comments at his expense.
* WarriorPoet: This is how he sees himself. Of course everyone else sees him as a complete and utter raving loony.

[[folder: Principal Kuno (九能 校長)]]
->Voiced by: Tateno Hitouchi (JP), Creator/ScottMcNeil (EN), Carlos del Campo (LA), Rafat Bazoo (AR)

The headmaster of Furinkan High School, and father of Tatewaki and Kodachi, this strange man abandoned his family for an extended vacation in Hawaii, coming back as what can essentially be considered a compound of the "obnoxious tourist" archetype and the stereotypical Hawaiian. Obsessed with cutting hair and short haircuts, delighting in making his students hate him and fight against him, Principal Kuno frequently throws his school into chaos to amuse himself.


* AbusiveDad: Almost makes Genma look like a model parent in comparison.
* {{Acrofatic}}: He's surprisingly athletic for all his bulk.
* AnnoyingLaugh: Well, not nearly as cacophonous as his daughter's, but it's ''very'' reminiscent of WesternAnimation/{{Woody Woodpecker}}'s SignatureLaugh.
* CatchPhrase: [[GratuitousEnglish "Oh My God!"]]
* CloudCuckooLander: Even crazier than his children, but not bloodthirsty.
* CombatPragmatist: An ineffective one, but still one.
* DeanBitterman: Relishes abusing his power over the students; seems to find their efforts to stop him hilarious. When Ranma is weakened by Happosai, tries to take advantage of it to forcibly cut Ranma's hair at last. He is more cheerful than most of the usual examples of this trope, though.
* EveryoneCallsHimBarkeep: His first name was never revealed, so everyone calls him "Principal" in English and Japanese.
* ForeignCultureFetish: The man is absolutely ''obsessed'' with Hawaii.
* GratuitousEnglish: In the Japanese version, [[KeepItForeign replaced with Gratuitous Hawaiian in the Viz translations]].
* HulaAndLuaus: Just came back from a 3-year vacation to Hawaii, and certainly acts like it.
* {{Jerkass}}: He's a dick. He knows it. He likes it. He's proud of it.
* LargeHam: Flashy and flamboyant, even by ''this'' series' standards.
* NonIdleRich: One has to give the anime incarnation of the character credit where it's due, not many people as wealthy as him would voluntarily work as a public high school's principal.
* ParentalNeglect: He essentially abandoned his children and left them alone for years to go and play with ukuleles, coconuts, and Hawaian resort luxuries.
* PetTheDog: A small one with Akane, when he whackedly but ''genuinely'' tried to help her get rid of her SuperDrowningSkills.

[[folder: Kodachi Kuno (九能 小太刀)]]
->Voiced by: Creator/SaekoShimazu (JP), Teryl Rothery (EN, seasons 1-5), Sylvia Zaradic (EN, seasons 6-7), Rocío Prado (LA), Hanan Shqer (AR)

Tatewaki Kuno's younger sister, whose revelation of kinship is only made in her second episode/chapter. The self-proclaimed "Black Rose of St. Hebereke Girls High School", Kodachi Kuno is a master of the fighting style [[MartialArtsAndCrafts "Martial Arts Rhythmic Gymnastics"]] and, while her general skill level may only be about the same as her brother's, she's a ruthlessly pragmatic fighter who is completely willing to use poisons and cheating to overcome her foe. Like her brother, she is unaware that Ranma Saotome is a GenderBender, but in her case that's because she's only seen Ranma transform once, in a situation where the switch could have been a variant of the NinjaLog, and no attempt has been made to explain it to her (unlike her brother). She fell obsessively in love with Ranma after he saved her from falling off of a roof, though he was the one who knocked her off in the first place, and refuses to let his reluctance to be near her and her lack of an official tie to him keep her away.


* AbhorrentAdmirer: An unusual example, since she's actually very attractive. However, Ranma still finds her repellent because of her personality and mental instability.
* AdaptationalNiceGuy: The anime gives her a few PetTheDog moments and makes it clear that, deep down, she really does love her family.
* AnnoyingLaugh: The her shrill, maniacal cackle that is one of her trademarks.
* AwLookTheyReallyDoLoveEachOther: On rare occasions, Kodachi shows familial love for Kuno.
* BadassNormal: Possibly the weakest martial artist of the lot (but in that case not far behind, as she can hold her own against either Shampoo and Ukyo, her brother, or Akane), but the one you least want to cross.
* {{Blackmail}}: Tried to blackmail Ranma with a doctored photo and does so again in a later arc to her brother/Ranma with another altered photo.
* TheBully: Ties with Happosai for position of the worst in the series about it; she just has less capacity for damage than he does.
* CatholicSchoolGirlsRule: She goes to an all girl Catholic school.
* ClingyJealousGirl: She has tried to kill Akane multiple times. Also she is unaware of Ranma's curse and views his same-gendered form (the girl) as a rival for the affections of his opposite-gendered form (the boy).
* CombatPragmatist: The dirtiest of the series. Partially {{Justified}}: in Martial Arts Rhythmic Gymnastics it's fully legal to use ''your own brother as weapon'', so it would be strange she wouldn't be this, but she fights dirty even for her style.
* CuteButCacophonic: She's fairly good looking, but, particularly in the Japanese audio, her laugh is almost as bad as [[{{LightNovel/Slayers}} Naga's]].
* DarkActionGirl: OK, she's no match for Ranma outside a Martial Arts Rhytmic Gymnastics match, but she can hit hard enough with a steel bar to hurt Ranma, do pratically ''anything'' with her ribbon, club an enemy with a dozen clubs ''per hand''...
* EeriePaleSkinnedBrunette: Pale white skin, black hair and purple eyes in the anime.
* ExoticWeaponSupremacy: Her main weapon of choice is a gymnastics ribbon, but she also turns the clubs into melee weapons and sometimes makes use of razor-edged hula-hoops and exploding balls as well.
* FluffyTamer: Her beloved pet "Midorigame", which basically means "Mr. Green Turtle" (though in a few episodes of the anime it is mistranslated as "Mr. Scaly Green"), is a 20'-30' alligator. She's also shown in the OAV opening "Where Do We Go From Here (You & Me)" to be feeding a massive shark as though it were a koi.
* GrievousHarmWithABody: She's not above using her own brother as a weapon.
* {{Hypocrite}}: Immensely. She talks about honor in a fight, but would resort to dirty tricks BEFORE a match, and would justify it with twisted logic ("Cheater? I believe in fighting fair, before the match of course!").
* IconicOutfit: Her famous mint-green gymnastics leotard, which she apparently wears under her clothes 24-7.
* ImprobableWeaponUser: Her standard weapon is a rhytmic gymnastics ribbon, but she has weaponized all the items of rhytmic gymnastics and ''[[UpToEleven her own brother]]''.
* {{Jerkass}}: Much like the rest of her dear family.
* LeotardOfPower: Kodachi has been shown to wear her characteristic leotard under virtually all her clothing, presumably because it permits a superior range of motion while in combat.
* MadLove: Kodachi is not above using dirty tricks such as blackmail and paralysis powder in her pursuit of Ranma. She admits that she knows he doesn't love her, not that this actually ''stops'' her.
* ManipulativeBitch: Tries to pull this off, but her reputation is such that everyone's on guard for it, so it never works.
* {{Mooks}}: Her gymnastic team.
* NoblewomansLaugh: Taken to a ridiculous extreme.
* PetalPower: She often has black rose petals around her. Usually incorporated into her exits or entrance, but occasionally involved in an attack.
* PetTheDog: In the anime, she once provided Ranma and Genma with free room and board after they were kicked out of the Tendo house.
* PosterGalleryBedroom: A bit less blatant than her brother, but still likes to have large-scale images of Ranma to admire. She's not pleased when her brother purloins one of these [[DartboardOfHate to use as target practice]].
%%* PsychopathicWomanchild
* RescueRomance: She falls for Ranma when he [[FallingIntoHisArms saves her from taking a bad fall]].
* RichBitch: Very bitchy and made very wealthy in the anime.
* SheFu: She practices [[MartialArtsAndCrafts Martial Arts Rhythmic Gymnastics]]; what did you expect?
* SomethingAboutARose: Sticking a rose in her mouth as a dramatic gesture is practically her trademark. She also uses rose bouquets to disguise bombs and even creates her own flurry of rose petals when she wants to make a dramatic exit.
* TryingToCatchMeFightingDirty: She tries to ambush and beat up her opponents prior to the scheduled matches, uses dirty tricks, likes to use knockout powder, is a massive {{Loophole Abuse}}r, etc.
* WhipItGood: As mentioned above, her ribbon is her weapon of choice and she is a master with it.
* {{Yandere}}: She is completely infatuated with Ranma, and like Shampoo, will go to any lengths to be with him, albeit her methods are usually more extreme (i.e. blackmail, paralysis powder, etc.)
