Jerk with a Heart of Gold/Anime and Manga


 * In To Aru Majutsu no Index we have Accelerator (who throws one Crowning Moment of Awesome after another) and Stiyl who were both introduced (and still are) as total heartless characters but were shown to have a heart of gold whenever it comes to their loved ones (Last Order and Index respectively)...
 * Bad Bird from Samurai Pizza Cats gets into this sometimes. Especially when his childhood friend Carla is around. Guido also fits, though being one of the good guys, he has more "Heart", and a lot less "jerk".
 * Zelgadis of the Slayers franchise, namely the anime, is definitely this; he's cold, arrogant, and even haughty at times, but he just wants to be human again, truly cares for his companions, and has a soft spot for the princess Amelia. In the original novels, though, he is more of a straight-up Jerkass.
 * The novel-exclusive character Luke is also this trope, almost identically fitting it the way Zelgadis does.
 * Ranma Saotome, in the self-titled Ranma One Half. And, by the end of the series, The Rival Ryōga.
 * Also Akane Tendo, although in her case the proportions might be reversed (i.e. mostly nice, but a real jerk when inclined).
 * Genma Saotome maybe one as well. While he maybe selfish and abusive towards Ranma, he still cares about his son. In a Crowning Moment of Heartwarming, he gives a young Ranma his blanket when he's cold.
 * Similarly, Inuyasha, an Expy of Ranma, cranked up to 11. Rumiko Takahashi seems to like these.
 * Don't forget Ataru Moroboshi of Urusei Yatsura, who combines this with being a Casanova Wannabe. It's strongly hinted that the reason Lum loves him so much is because she can see the noble parts of him that most others (including himself) can't.
 * Gakuen Alice has a great example in Natsume Hyuuga, who is pretty much horrible to Mikan from the get-go and remains so even as he gradually falls for her. His behavior towards Mikan changes in small steps over the course of the manga, and he has gotten to the point where he would give his own life for her sake. But all in all, while he is rather cold towards most others you do sense his innate kindness, especially through his interactions with Ruka or You-chan. You also eventually find out that.
 * Kogoro Mouri from Detective Conan defines this. He's lecherous, he's an alcoholic, and he has a HE-UUUGE ego. And let's not forget about the way he treats Conan for simply being smarter than him. However, don't let that fool you: he has shown to care deeply for his family, specially his "little girl" Ran. He also told Heiji's father he went to far when he punched his son and made him bleed. Ironic, huh?
 * Let's not forget what happened when one of his friends was murdered under his very nose in a Hot Springs Episode  For one time, the guy was awesome. SERIOUSLY awesome
 * In Part I of Naruto, the eponymous character was a brash, temperamental brat fond of picking fights with everyone and completely lacking in social graces, but he was also surprisingly kind to people like Inari and one of the few to interact with Gaara as an equal rather than with fear or hate. During the second part of Naruto, however, his previous slightly jerky attitude was downplayed as he matured both emotionally and physically."
 * Sasuke on the other hand, is a complicated issue. The scene where he saved Naruto's life and told Naruto that it was his duty to save Sakura, where he said he didn't want to lose those important to him doesn't leave any opening for interpretation. He was a Jerk With a Heart of Gold... sadly, the emphasis is on was.
 * Sai is also introduced as an abrasive Jerkass, but mellows out and turns into one of these after Naruto establishes bonds with him.
 * Kanako Urashima of Love Hina could be considered this, as despite hating Naru (and even punching her in the face), she  Keitaro even later comments that he "always admired her consideration for others".
 * Eikichi Onizuka, Great Teacher Onizuka
 * Yusuke Urameshi and Kazuma Kuwabara, Yu Yu Hakusho. Hiei goes beyond this and all the way to Noble Demon. Yusuke REALLY embodies this trope. He's a street fighter, a teenage punk, and generally has an extremely negative outlook on life. He lacks any basic manners of a basic human being, but he really cannot stand those who hurt the innocent. He's also EXTREMELY overprotective of his friends, particularly Keiko.
 * Sensui is a rare villainous example: Although he planned to unleash a vast horde of demons upon humanity; he only done so because he conveniently found a few dozen humans torturing demons for fun. He had a warped-mind that day, and since then only cared about killing people, even children.
 * Officer Ohta, Patlabor. He once went to an arranged date, did like the girl quite a lot... and helped her out when he learnt that she was in love with someone else and the guy was in serious trouble.
 * Ryou Shirogane from Tokyo Mew Mew.
 * Kaito Doumoto fromMermaid Melody Pichi Pichi Pitch.
 * In an odd main character variation, Sara Werec of Soukou no Strain. The difference is, we already know how good of a person she is, and how she's put away her kind and friendly nature because she blames herself for her dead schoolmates and just wants to stop her brother. The Space Squadron, however, does not.
 * Cross Dresser Izumi Kido from Tenshi Ja Nai
 * Yasumi from the comic strip Potemayo.
 * Mad Scientist Lloyd from Code Geass cares about his Knightmare Frame more than people; openly mocks the royals (and, well, everyone else too) and generally seems to have absolutely no respect for rank or privilege (though he possesses both); proposes to Milly just so he can acquire her Knightmare Frame (and then never mentions it again); and even teases Suzaku when he's extremely unhinged about  (to be fair, he may not have known much about Suzaku's feelings, but still). However, he also took Suzaku on as a pilot for the Lancelot, at a time when discrimination against Japanese people was commonplace; and he and Cecile come to the rescue of the Ashford students when they're held hostage by the Black Knights.
 * Forget not that he was also one of the few people to clap and cheer when Suzaku was made a knight; It might be he acts like that in deliberate defiance of his Britannian heritage, considering what gits they are.
 * And in one of the side materials, he refers to himself as having no soul. So it might just be that he doesn't care about anyone except his robot-building henchman and his robot-piloting henchman.
 * Tsume from Wolf's Rain. Always acts tough and cynical and frequently argues with the other wolves, especially Kiba, but is often protective of them, especially the younger wolf Toboe who idolizes him.
 * Also to some extent the human Quent. When he's not obsessed with wolf-hunting he can be a fairly decent guy, if you buy him a drink.
 * Spike Spiegel of Cowboy Bebop is a lazy, snarky bastard who's unafraid to fight dirty or start a fight for the fun of it. He's also very caring towards his crew, certainly doesn't mind helping those in need, took Ed, Ein, and Faye on board the ship (despite the fact that he hates "pets, kids, and women with attitude"), and never hesitates to place Honor Before Reason.
 * The titular character in Suzumiya Haruhi. Kyon likely also qualifies for this trope. He's prone to presenting himself as a world weary Deadpan Snarker but he has hidden affection for SOS-dan that he hides behind his perpretual sigh and frown.
 * Disagreed. Kyon usually gives Haruhi the cold treatment while snarking away in his internal monologue, making him more of a Tsundere. Haruhi fits this trope more, as she does treat the Brigade members very well, like after Kyon fell into a coma in Disappearance and when Yuki fell sick because of the Sky Canopy Dominon in Snow Mountain Syndrome. Most recently seen in the end of the beta storyline of Dissociation.
 * Several characters in The Prince of Tennis, starting with the main character himself. Others are: Jin Akutsu (ex Jerkass), Kaoru Kaidoh (who borders on Tsundere, actually - and in the anime, nearly drowns trying to save a puppy), Akaya Kirihara, Ryo Shishido, Genichirou Sanada, Hiyoshi Wakashi, Kevin Smith (after going through both Break the Haughty and Character Development), Keigo Atobe, etc.
 * Shizuo Heiwajima from Durarara acts like a complete Jerkass at some points, but it turns out that, when you don't activate his Hair-Trigger Temper, he's actually just a socially inept sweetheart. He deeply cares about his brother and basically anybody who isn't Izaya Orihara.
 * Harlem from Papuwa fits this trope towards Kotaro and Liquid.
 * Edward Elric from Fullmetal Alchemist appears this way to many characters - including his younger brother Alphonse, who constantly has to apologize for him in the trend of "Don't take it personally, he's like that with everybody and he's actually nice deep inside."
 * Greed might also belong to this category. He doesn't seem to be as selfish and insensitive as he claims to be and is occasionally quite serviceable.
 * Roy Mustang makes it into this category as well, frequently appearing callous and arrogant to those (Ed in particular) who don't understand his past and/or motives.
 * Olivier Milla Armstrong could also fit in this category.
 * Kujyou Kazune of Kamichama Karin.
 * Midou Ban in Get Backers has a mocking nickname for nearly everyone (monkey trainer, thread spool, computer boy, etc.), is selfish, sneaky, gropes women constantly, and is generally just not a nice guy to be around... unless your name is Ginji, and you get to see that "Ban-chan" is really just a cuddly, misunderstood dork.
 * Junichi Sato seems to really, REALLY like this trope in the anime he directs:
 * Mamoru Chiba, the title character's love interest in Sailor Moon, starts out as a Deadpan Snarker who enjoys teasing Usagi about everything.
 * Hayate from Prétear, the Tall, Dark and Snarky knight who
 * Fakir, the jerkish, controlling guardian of Mytho in Princess Tutu, who turns out to be using the tough exterior to hide his fear of
 * Layla Hamilton from Kaleido Star, the Broken Bird who is as tough on herself as she is on new recruits to the Kaleido stage and has quite the daddy issues.
 * Black Rose and Antonio Fabiani from Ashita no Nadja.
 * In Medabots, Couch Mountain seems like a cruel man who makes students run laps for no reason, and seems to be doing deals with shady characters. In reality, he was trying to buy land to put up a park for poor children. And then, in the end, he makes the main characters run some more laps for staying up late.
 * Lead bully Samatha might also be one of these, charitably keeping around her totally incompetent minion Spyke and often helping the heroes out when they really need it. She just does a damn good job at hiding it (and does actually fire Spyke in one episode, though not without provocation).
 * Youichi Hiruma, from Eyeshield 21. He never refers to anyone by their real name, only by his personal nickname, and all his personal nicknames start with "fucking" (toned down to "damn" in Viz's translation of the manga). (Sena is "Fucking Shrimp", Mamori is "Fucking Manager", and then there's his best friend Kurita, "Fucking Fatass", and so on.) He's a violent gun nut who slings a constant string of verbal and physical abuse on his team, uses blackmail to get his way like some people say "please", and lies like it was going out of style. He also never fails to reward perseverance, dedication, and effort as long as the team doesn't suffer for it, has his own unique brand of showing affection which he doles out with regularity, and puts himself through all the same crap that worse crap than he puts everyone else through.
 * One notable scene was when an exhausted Yukimitsu made it to the top of the Tokyo Tower, as part of Hiruma's tournament to get more teammates. However, Yukimitsu's bag of ice, that he was suppose to bring up to the tower, had all melted. But secretly, Hiruma slipped in an ice cube and congratulated him for making it.
 * Another example is when an enraged Gaoh was rampaging in the stands looking for someone who insulted someone he considered a Worthy Opponent, Hiruma jumped in front of Mamori and Suzuna to protect them from harm.
 * Linebacker Habishira. Mostly out of blackmail, but even after being released by Hiruma so they can practice, they still help Deimon out a lot.
 * Marco. All he wanted to do was win the Christmas Bowl for his girlfriend, Maria, and show her the rising sun after the victory, but lost sight when Maria disproved of using Gaou as a weapon.
 * Daichi from Dennou Coil.
 * Randou from Pretty Face. The jerk part caused basically everyone he was in contact with to either fear or hate him, except for his crush, who saw the gold part in him. Eventually the gold part becomes more notable.
 * Asada from Team Medical Dragon frequently acts like a misogynistic, perverted, carefree Jerkass. Then a patient gets in with an improbable injury, he saves the day and proceeds to lecture everyone about how the patients' well-being is the most sacred priority. And he's totally incorruptible.
 * Nicholas D. Wolfwood from Trigun is an epic Jerk With a Heart of Gold. When you get over the fact that he insults you, beats you up out of "affection" and struggles with the Sliding Scale of Idealism Versus Cynicism by sadistically killing bad guys, he's actually an altruistic and generous dude.
 * In Soul Eater, Soul and Black Star border on this at times, as Black Star often seems so full of himself he hardly has time to care about anyone else, and Soul is usually the Deadpan Snarker that appears to only really care about advancing himself at times. However, both care about their friends and partners, with Black Star willing to "share the stage" with Tsubaki, while Soul regularly protects Maka from harm.
 * Don't forget Mifune, who is one of the best swordsmen in the world and regularly faces off against Black Star, yet carries around candies for children and swings his sword for a small child witch named Angela.
 * In a way, Black Star's treatment of Crona could be seen as this. While he fights in the only way he knows how, brute force, he does make his own kind of attempt to get through to them by insisting that Crona could have someone to rely on in him, the one around whom the world revolves (or something to that effect). And then there's Black Star.
 * Tomoya Okazaki from Clannad. Yes, he tries to project the front of a lazy ass who delights in twisting the truth for practical jokes on anyone and everyone (leading to some impressive amounts of confusion and misunderstanding among the more naive cast -- Nagisa especially), and tries to look all though and detached. Yet he ends up trying to help the mains of every arc, without a second thought, and has been seen to drop Manly Tears, or openly crying in frustration and sadness, at the endings of some.
 * Several characters from the Gundam franchise fit in her perfectly.
 * Shin Asuka from Gundam Seed Destiny certainly fits into this trope well. He initially seems to be a troubled youth with authority problems and chews out anyone who tries to help him in most ways, . As the series goes on, it becomes more and more obvious about this, but that doesn't stop the fanbase from pulling a Flanderization on the guy and making him 'emo.'
 * Also, from Gundam 00. He pretends to be a lazy Handsome Lech in the beginning, but that's a Jerkass Facade destined to both   and.
 * Kamille Vidan Yes, the girly-looking and girly-named boy has huge Wangst and can be a big Mood Swinger, but he also genuinely cares for those he loves and tries to help them.
 * His rival Jerid Messa is also one, though quite more brutal. Basically, he's a huge Jerkass, but if you do manage to make him care for you, he'll genuinely do so... and it will be your downfall
 * Byakuya Kuchiki from Bleach. He is shown to be very arrogant and snobby (possibly to do with his noble family upbringing). However, he has been proven on more than one occasion to be fiercely devoted to his stepsister, Rukia.
 * Same goes for his lieutenant, Renji Abarai, who is just as devoted to Rukia as well as very Hot-Blooded and loyal to those he cares for.
 * Ichigo Kurosaki, the main character.
 * Kensei Muguruma. He and his lieutenant Mashiro get along like an ice cube and the sun, He also saved Hisagi from a Hollow when he was young and tried to get him to smile, although he did it in a hilariously frightening manner.
 * Moe Shishigawara and Riruka Dokugamine.
 * Domyoji Tsukasa of Hana Yori Dango, who manages to be a sympathetic male lead despite frequently beating up random bystanders for no reason.
 * Kyoushiro Shirogane from Ginga Densetsu Weed.
 * Magari Kazuma of Nora spends the first two volumes of the series treating the titular Hot-Blooded demon like a misbehaving puppy and most of his classmates like idiots, claiming flatly to make decisions based solely on which outcome will most benefit or least inconvenience him, and being generally bastardly to everyone. And yet... he will do anything to protect the people around him, often foregoing magic and just leaping irrationally to their defense, quite at odds with his normal Magnificent Bastard-in-training persona. And you really don't want to imply that humans are inferior; the results are not pretty.
 * Ryuji Takasu from Toradora, in a manner of speaking. He isn't a jerk at all, but his sheer appearance is menacing enough that people assume he's a Delinquent and give him a wide berth.
 * Toru Muhyo in Muhyo and Roji. While he is typically fairly cold, showing either irritation with or disdain for those around him, he often does this to teach Roji subtle lessons, and typically goes out of his way to get the best possible result for the ghosts he deals with, even when he seems to be taking a harsh stance on them.
 * Rival Executor Daranimaru Goryo might fit into this trope as well. Although he may appear a ruthless bastard, he actually shows genuine concern for his assistant Ebisu, and even cries over him. Twice.
 * General Cross Marian from D.Gray-Man put his cute little traumatized apprentice Allen Walker through training from hell, which included a lot of stuff that had less to do with becoming an exorcist and more with dumping his considerable debts onto Allen. But he does care about his "idiot apprentice" and has MANY Crowning Moment Of Awesomes in the series, and we see him.
 * Chamo of Mahou Sensei Negima seems to fall under this. Sure, he's a Dirty Old Man in ermine form, and constantly tries to manipulate people for his own gain... but he never puts his own goals above the safety of the rest of group, tries to make sure everybody else benefits along with him, and generally tries to make himself as useful as possible, even when an ermine generally wouldn't be able to do anything.
 * Ayaka Yukihiro has her moments as well -- when she's not being a spoiled Ojou, she shows herself to have strong principles and be genuinely quite caring of others.
 * Tosaka seems to be like this too. He constantly bullies Ako, and constantly complains about her, Negi, and everyone else, and He also   And then,
 * Dynamis fits the bill as well. At first he seemed to be an aloof villian, who is completely condescending to Fate's minions, saying what a shame it is that Cosmo Entelecheia has gone from being a massive organization to relying on four little girls to do their dirty work. Then he thanks those same minions for staying with them, because without them it would have been impossible for them to have gotten as far as they have, and that they should be proud of themselves for surpassing the Cosmo Entelecheia of the past. Koyomi even lampshades it.
 * Hamel, the titular Violinist of Hameln (manga continuity only). He purposely humiliates people, charges exorbitant prices for anyone who hears his music, plans zany schemes to make money, actually uses his friends as ammunition and is so selfish he'd rather eat his crow companion than go hungry for even a little while. And believe it or not, he really is a good guy underneath it all.
 * Sawamura Takeshi in Wa ga na wa Umishi seems to be this, but only because the main character Rintarou rubs him the wrong way. He's not above hitting and threatening Rin frequently, but he's also saved Rin's life more than once. Whenever there's a job to be done he's the man to do it.
 * Takuto, the male protagonist of Full Moon O Sagashite, is a mild example (bit moreso in the manga) of Jerk With a Heart of Gold, as his mannerisms are rather limited to his way of speaking to others. Occasionally rude, anti-social, and snarky ("baka" is his favorite word) he will always say the exact opposite of how he truly feels, yet when nobody's looking, he'll do something incredibly sweet. Just make sure you don't blink because you'll miss it. Because of an overwhelming number of "tsu-tsun" traits, he can also be classified as the Type A male Tsundere. By the end of the anime series, his jerkish side pretty much vanishes for
 * Roronoa Zoro from One Piece. Acts distant and somewhat insensitive to others (and outright insults Sanji a lot of the time), but has shown himself willing to go through Hell and high water for his True Companions,
 * He's had plenty of pet the dog moments too. Mostly to do with Chopper or kids.
 * Nami as well. She originally had to act like a thieving jerk in order to help her village from a ruthless gang lord, but after she was freed from her debt made it apparent that she was still as greedy and manipulative as ever. She has shown a soft spot for women and children and, thanks to Character Development, even was willing to give up part of her wealth to Rolling Lola out of thanks and was later forgave a former member of the gang that had terrorized her village and tried to help him win back a kidnapped mermaid friend with a large part of the wealth collected by the crew.
 * Smoker did this in one scene, where a little girl with a 3 layer ice-cream cone bumps into him, instead of getting pissed at her for staining his suit, he gives her money to buy a 5 layer ice-cream cone,and apologizes to her.
 * No mention of what is probably the best example of One Piece? I bring you Curly Dadan, Luffy and Ace's foster mother. She constantly complain about how much of a nuisance Luffy and Ace are, and often treats them not too kindly, but in the end she is very protective of them. She can't even praise them without calling them "idiots" or "assholes".
 * Kittan Bachika from Tengen Toppa Gurren Lagann usually comes off as loud-mouthed and a Drill Sergeant Nasty, but he's ultra-protective of his sisters (even their eye-appealing curvaceous figures) and puts his life before that of his team.
 * Tasuki in Fushigi Yuugi is a thieving, Hot-Blooded, hard-drinking He-Man Woman Hater who is constantly offending the hell out of his teammates with obnoxiously blunt remarks both intentional and unintentional. But he's also ferociously loyal to the group, cries the hardest at, reams out brainwashed Tamahome for hurting Miaka's feelings and breaking her arm. To top it off, he is nearly beaten to death making a You Shall Not Pass sacrifice for her.
 * Seto Kaiba amd Katsuya Jounouchi from Yu-Gi-Oh! Kaiba has emphasis on the jerk part, Jounouchi on the heart of gold one.
 * In Scryed, Kazuma is known as a mercenary who will take just about any job if the pay is right, but his most vicious moments are when he's found out that his target has been abusing people, or threatening children, or generally doing anything that makes the audience say "Kazuma, please kick his ass". And when  he abandons all strategy and madly swings his fist at anything with a HOLY logo on it.
 * In Karneval, Gareki, Hirato and Akari can all be Jerk Asses, considering that Gareki's personality is rather Tsundere and the latter two are rather cold toward people. BUT Gareki obviously has a weak spot for Nai's innocence (though it won't spare the poor kid getting bonked in the head, and all the other annoying brats in the world can go rot for all he cares), Hirato seems to effectively hide how much he cares for his crew and how often he makes certain of Nai's safety, and Akari is harshly vocal about Hirato's apparent callousness toward his crew and the people essentially under his care.
 * Kiyoshiro from Shattered Angels. He gets better once he sees his brother again and discovers what a monster he really is.
 * Holland of Eureka Seven. Though it takes a lot of digging to find that heart of gold; he tends to come across as just a straight-up Jerkass earlier in the series.
 * Compared to his own brother, Holland is practically a saint.
 * Dola from Castle in The Sky. She's a crusty, tough-talking old lady who is abrasive, bossy, and even controlling of her boys. She even tries to kidnap Sheeta (and steal her crystal) at the beginning of the movie. Later on, she grudgingly agrees to let Pazu help her save Sheeta and agree to take them aboard her ship. (While she's playing chess with her husband, who questions her about her affections for the kids, her response is, "Whaddaya mean by that, ya old fool?! I'm after treasure. That's all." Deep down, however, she's actually a softhearted person who comes to admire Pazu and Sheeta for their loyalty toward each other. (She does a brief double-take, though, when she overhears Pazu telling Sheeta that Dola is "much nicer than she pretends to be.")
 * Guts from Berserk qualifies. He's violent, cruel, cold, and obsessed with his personal goals, which are often achieved at great cost or risk to others. But unlike his nemesis, he genuinely cares about the people around him, is a compassionate leader, and his distant, uncaring demeanor seems to come from a desire to keep people away from the danger he's constantly in. It ... doesn't always work out that way. But he tries.
 * In a couple of recent arcs, Gin from Rosario to Vampire has had some character development that takes him from the Jerkass / Handsome Lech territory he's been inhabiting for most of the series to Jerk With a Heart of Gold when he
 * Drew from the Hoenn arc of Pokémon is like this. He especially loves switching between both halves of this trope when he's interacting with May.
 * Trip from Best Wishes also starts out as a Jerkass but is recently revealed to be one of these as well as something else toward Ash.
 * Gold from the Pokémon Special manga fits this one to a T.
 * Lunar of Seto no Hanayome starts as a Bitch in Sheep's Clothing, but there are a few incidents that make it clear that she really does care about Nagasumi, at least a little.
 * Many characters in Axis Powers Hetalia act like this at some point or another, being jerks to each other during conflicts but genuinely showing kindness and concern for younger nations, animals or their subordinates: America, England, France, Germany, Austria, Prussia...
 * Muta from The Cat Returns is literally called a Jerk With a Heart of Gold at one point. He fits the build exactly.
 * Giroro of Keroro Gunsou. He's normally a hard-boiled warrior, but he's proven that he's willing to go all out to protect the squad. And even moreso, Natsumi. He also shows his softer side to his cat.
 * Batou from Ghost in The Shell Stand Alone Complex is a borderline case (in terms of being a Jerkass at all, not the heart of gold part). He's basically a good guy, but he can be a bit of a jerk.
 * More pronounced in the manga, where he's a Deadpan Snarker who's Vitriolic Best Buds with his old friend The Major.
 * Kurosaki/ from Dengeki Daisy definitely qualifies. In person, he's rude and obnoxious. Over the phone... not so much.
 * Knuckles from Sonic X.
 * Asuka Langley Soryu of Neon Genesis Evangelion is incredibly Hot-Blooded and a wicked Tsundere, but despite that, she still tries to be compassionate to Shinji. Unfortunately, he's just too secluded to open up to her, leading to many angry confrontations between the two over his cowardice and her arrogance. Worse, she hates Rei with a passion for her emotionless nature and unnatural talent for piloting an Eva. Her Rebuild counterpart, Asuka Langley Shikinami, dials back the nastiness and predjudice- but not too terribly.
 * Gendo Ikari is also a prime example- he's shuttered off the world to proceed with Instrumentality, doing nothing even close to morally correct, but in reality, he actually wants, and has a dormant regret for the way he treats Shinji as a father.
 * Ryoji Kaji has made a reputation with Misato for being an insensitive, underhanded, and slobbish man. The first trait is a misunderstanding, while the third seems to be just to tease and spite her. The second, however, is VERY true...
 * Several characters from Nadia: The Secret of Blue Water also qualify. Nadia herself wavers between being a complete Jerkass and a Not Good With People sort of person, but in the canonical episodes of the story, she fits into this trope. Aside from being suspicious of other people, she has a nasty, quick temper and gets angry quite easily, misunderstanding everyone's actions at the drop of a hat. That said, she is also shown growing to care for Jean, as evidenced by her attempt to comfort him about his father's death, and even suggesting him to build another aircraft to cheer him up. She even brings him a half-baked dish of seaweed. She's also transformed by the end of the show into a genuinely caring person.
 * Grandis Granva, most definitely, although Sanson and Hanson could both qualify, too.
 * Captain Nemo. Most of the time he is very reserved and sometimes makes harsh decisions, but he's fundamentally a good person who cares for his crew and mainly wants to stop Gargoyle from destroying the world. He even comes to see Jean as a surrogate son and even has a soft spot for Nadia.
 * Genjou Sanzo from Saiyuki counts. He makes (empty) death threats at his companions, calls them his servants, and often employs physical violence on them (Paper Fan of Doom with Goku, gunshots with Gojyo that he obviously means to miss because he is a ridiculously good shot) - BUT he rescues Goku and keeps the kid around even though there's no advantage in doing so,, gives a pep talk veiled in rudeness to  , repeatedly says he won't interfere to help/is not on anyone's side, but then proceeds to do so, often with an excuse. The examples can go on.
 * Renjo Hotsuma in Uragiri wa Boku no Namae wo Shitteiru.
 * Mamoru Takamura in Hajime no Ippo is about 80% Jerkass and 20% this. Thing is, boxing happens to be the one thing he happens to take seriously, and therefore takes it very seriously if a boxer disgraces himself or respects a boxer that fights well, regardless of the results of the fight. Aoki and Kimura get especially surprised of him when he approaches Ippo, not to mock him, but to congratulate him after . He was also extremely brokenhearted after the, when he finds out that , he literally cries. For a guy that beats up his fans and grabs people's cocks in the shower on a regular basis, this shows that he at least has some kind of idea of common sense.
 * Also Takeshi Sendoh, who is Hot-Blooded and a borderline Blood Knight... but actually started fighting to protect people rather than hurting them in purpose.
 * Yuuki Natsuno in Shiki is a bit cold and distant towards others not to mention he hates the village helives in, but when a vampire attack occurs he isn't afraid to put his life on the line to stop them.
 * Manabizaki from SWOT is more concerned with studying than with people. He insults people and treats everyone as beneath him since he has "the greatest brain in the universe." Or, at least, he claims not to care. He's come to the rescue of a wimpy male classmate (later a friend) more than once and an ex-delinquent girl he's developed a crush on. His sputtered and obvious excuse? The people attacking them were making too much noise for him too study. Or he was just on the way to a test/class/study-session and the guys were in the way.
 * Rika of Digimon Tamers goes from Jerkass to this thanks to Character Development and her Defrosting Ice Queen status. By the end of the series, she's pretty much gotten rid of most of the "jerk" tendencies.
 * Chiharu Eniwa of manga series Girl Got Game is one. Almost as soon as he meets Kyo, he fights with "him" and constantly shouts at and argues with "him." He does have a short temper, but he's actaully nicer than he lets on. When he does help someone (usually Kyo), he'll often give the usual "I'm only helping so you don't get mad at me later," or some other half-hearted excuse.
 * Naoki Shinjyo from Future GPX Cyber Formula was a Jerkass when his boss makes a secondary team with the team he belongs to. He lashes out at his team's new mechanics and has gets angry over his poor driving skills despite being The Ace, but once Miki Jounouchi blames him for having no respect towards mechanics and he proves himself as a true racer, he begins to show more of his softer side.
 * Karl Lichter von Randoll also started out as a arrogant racer when he puts down other racers, saying that he's better than anyone, but after the race with Hayato in the Spanish race that ended in his defeat, he slowly softens up and begins to have a sense of chivalry.
 * Alto Saotome from Macross Frontier acts like a jerk to a lot of people and in the beginning mutters about how much he hates his home, Frontier, but in spite of it does everything he can to protect it. He's particularly a Jerkass with Sheryl at her teasing, leading to the obvious conclusion.
 * Hitoyoshi Zenkichi from Medaka Box definitely qualifies, he bitches and moans about having to do things all the time, will chew someone out in a moments notice, gives up constantly and he goes to extreme lengths to show how awesome he is, but if you even think about doing something to one of his friends he will make sure you go down, even if he has to go down with you.
 * Van of Gun X Sword: got a town that needs saving? He'll dismiss your plea because it has "nothing to do with" him, but then he'll think better of it, especially after his Morality Pet Wendy prompts him a little (or gives him an outright scolding). Speaking of Wendy, he takes her for granted much of the time and occasionally treats her rudely, but if she's sick, in danger, or even just unhappy, he can be surprisingly tender towards her.
 * Mitsuba from Mitsudomoe has a dismissive and superior attitude towards everybody. Yet, she just as often slips up and reveals that there's some genuine kindness in her. One of her earliest examples is the replacement pencil cases Futaba made. Mitsuba kept using hers well after her sisters no longer were.
 * In Freezing, the third years may be major, major jerks who were obsessed with beating the crap out of the main character for unjustified reasons, but they're still soldiers trained to save humanity from Eldritch Abominations. During the Academy Siege, they were in the front lines covering for everybody else.
 * Tanimoto of Kenichi the Mightiest Disciple. He acts like a Jerkass towards Kenichi, but when push comes to shove, he's willing to throw his lot in with the Shipaku Alliance.
 * Nijima also counts; while he seemingly doesn't care about the desires or well being of the Shinpaku Alliance (especially Kenichi), he's shown that his is willing to stick out his own neck for the team when he really needs to.
 * Akira Hongo, the "God Fist" of YAMI's One Shadow Nine Fists, proves to be this as well. He looks and acts like a very aloof fighter, but over time he is revealed to have been a very good mentor to his now-deceased prize student Sho Kanou (and later, to Kanou's fellow students under him as well), and he didn't take it very well when he learned that Kanou had died at the end of the D of D Tournament arc. It's also indicated that he's always respected the bond between master and student and Kenichi earns his respect for standing up for Kanou's self-sacrifice to protect Miu during the aforementioned D of D.
 * Vegeta to the max. Comes to destroy the earth, slaughters a village of innocent Namekians, threw out the good he gained over ten years to become evil all over again as a Majin, flips out when his family is threatened, masterminds the defeat of Kid Buu with an appeal the Earthlings... Yeah, I think he counts.
 * Then, of course, there's Piccolo: son of Dragonball's biggest Big Bad, kills the hero, mentors Gohan, gives his life to save said Gohan, and eventually becomes the closest thing the True Companions have to a Team Dad. Also undoubtedly counts.
 * On a much smaller scale, Yajirobe. A belligerent glutton who vocally wants nothing to do with the other Z-Warriors, he still always ends up coming to their aid when they really need it.
 * Try explaining to one of Taiga's victims that she buys presents for families and orphans every Christmas.
 * Gajeel from Fairy Tail is something between this and Tsundere depending on the situation. He didn't save Natsu from getting fried alive by Laxus because he cares about him, he just wanted to make sure Natsu was around to get his revenge on. And don't even get me started on his relationship with Levi.
 * Nezumi from No. 6. He can be a jerkass at the very least. But he also sings to Dogkeeper's dying pack members to ease their suffering, to say nothing of what he'll do where Shion is concerned.
 * Oddly, Himari's possessor comes off as this in Mawaru Penguindrum. This is the same entity that horribly insults a young girl like Ringo all over when summoning her an Shoma to her presence, and some episodes later
 * Rouce, a.k.a. Red Lightning a.k.a. Mink's father in "Dragon Half". A once-renowned warrior whose recent "exploits" consist of fighting his dragon wife, hitting on any attractive woman (regardless of her availability), faking life-threatening diseases to get out of hunting for food, and pulling down his own daughter's pants, it seems the only thing he's good at now is lying. However, he does get a moment of off-panel awesomeness singlehandedly slaughtering a horde of monsters about to eat his wife and daughter. Though he appears to be sleeping when the two return to camp, the blood on his sword (and trademark "R" cut on the monsters' corpses) make it pretty clear that he's the one who saved them.
 * Helen from Claymore. When she was first introduce, she was a total bitch toward Clare, the main character, and was perceived as a bully among the warriors in general (second only to Undine, who is another case altogether). But once you get to a level of understanding with her - maybe even save each other's lives in the process - you have Helen's back till the end, and she'll never let you down.
 * Black Bird: Kyo can be a complete and utter Jerkass.... However, he does loves Misao, is willing to die for her and do anything to make her happy, and can be incredibly sweet and gentle to anyone smaller or weaker than himself (particularly children, which is why Tarou is so devoted to him).
 * While Pauley Cracker from Kimba the White Lion can be sarcastic and pushy, he cares deeply for his friends and is willing to do what it takes to help them.
 * Hanaukyo Maid Tai. Konoe, especially in 'La Verite''. She starts off very stern and strict with Taro, but ends up becoming friendly toward him.
 * Kyou Sohma from Fruits Basket. Despite being a jerk to everyone, he develops great affection for Tohru, whom he eventually
 * Yue Kato and Sakuya Kira from Angel Sanctuary.
 * Gokudera Hayato of Katekyo Hitman Reborn. He's kind of a jerk, especially to Yamamoto but just check out how affectionate and caring he gets whenever Tsuna's around...
 * Gravitation: Eiri Yuki.
 * Tomoe from Kamisama Kiss is normally sarcastic, rude and highly critical of just about anything Nanami does. But if anybody else tries to insult her and/or criticize her he is quick to come to her defense and if you hurt or threaten Nanami in any way, shape or form you're in for a world of pain.
 * Rin and her assistant, Mimi, in Mnemosyne.
