Dark Is Not Evil/Anime and Manga

The majority of anime/manga examples are themselves an example of the cultural differences between Japan and the US. Contrary to the Anglosphere, in the East, good guys wear black and bad guys wear white.

"Well, that was nice. You're not so bad after all. You just dress bad."
 * In the Nightschool, there are demons, vampires, witches, and people with horns spikes and wings...and then you meet Genki Girl Rochelle, the cheerful Night keeper Sara, and Madam Chen, who just wants her coffee. In fact, most vampires are harmless pretty boys (until they become Rippers)
 * As in the video game, the Pokémon that look scary or "evil", like Houndoom, Shuppet, Duskull, and others, are just as capable of forming friendships with their trainers as any "cute" Pokémon, and frequently appear in perfectly normal settings. On more than one occasion, in fact, Ash and his friends were in fact helped out by Houndooms against Team Rocket.
 * Averted in the case of Deino's family, however. Their Pokédex entries make them out to be a race of Exclusively Evil monsters. Mind you, the early evolutions seem more like Woobie, Destroyer of Worlds examples since they can't see and biting everything is the only way they can understand their surroundings.
 * Hydreigon is actually a Woobie, Destroyer of Worlds if you think about it. For most of their lives they live as tiny dragons without any eyes that have to bite to determine their surroundings. Needless to say, this would piss other Pokémon off pretty easily and the main (only?) place you find them is full of Pokémon a lot bigger and tougher than a cute little Deino. After evolving it doesn't get much bigger and grows a second head with which it constantly fights. And it still can't see. Finally after a life of hardship (Even in real time training up to LV 64 will take a while without cheating) it evolves into Hydreigon and can see for the first time. People who have been deaf or blind most of their life but were given the ability to see thanks to science have been known to be profoundly stressed out by it and sometimes opt to switch back. So how do you think a giant pseudo-legendary Pokémon with no off button would handle seeing the world for the first time? Hydreigon aren't evil. They're depressing.
 * A shining example is Ash's Gliscor; despite becoming more confident in its abilities since evolving, it retains signs of the hyper crybaby it was as a Gligar. However, it isn't a Dark type at all (its fierce design likely fooled everyone into thinking otherwise).
 * Or Muk, a Walking Wasteland that basically loves everybody.
 * And then there's the tenth movie, Pokémon the Rise of Darkrai. The title Pokémon, whose special abilities involve being able to create nightmares (and in the story, cause eternal nightmares that can only be cured with a Lunar Wing), turns out to be one of the good guys here. Actually ends up saving everyone. The lord of nightmares. Darkrai Is Not Evil! Well...usually.
 * This trope is probably felt even stronger in Japan, where the Dark type is instead named the Evil type.
 * Giratina had "666" symbolism on its body (6 spikes, 6 legs and 6 ribs). OK, he's not "dark" in the traditional sense, but he's a Ghost-type, and Ghost is usually associated with darkness...plus the Reverse World ain't exactly a place of eternal sunshine.
 * Giratina is actually a representation of antimatter in the same way that Palkia and Dialga are time and space respectively. He's most likely simply a ghost not because he is in any form 'dead' so much as alive in a sense somehow opposite to normal Pokémon.
 * Giratina could best be seen as the Pokémon version of an Eldritch Abomination. He's more highly aggressive than "evil" though.
 * The new Legendary Zekrom is completely black, contrasting with the all-white Reshiram. Presumably, that doesn't mean he's evil (His typing is Dragon/Electric).
 * Zekrom is actually, arguably, more heroic than Reshiram, because while Reshiram is representative of Truth, Zekrom stands for Ideals.
 * Bonus points if you bought the White version of the games, where
 * A lot of adaptations make the Psychic gym leader Sabrina to be a villain, or at least a mean and bad person. Pokémon Zensho and The Electric Tale of Pikachu keep her game personalities, or actually they keep her "Good" character alignment and amplify it; she's borderline Moe in both, and extremely kind in the latter.
 * Despite how nasty Takuto looks, and even though he did, he's actually a pretty good guy, having given positive words to the protagonist.
 * Zorua and Zoroark, both Dark-types, look incredibly evil, with moves themed around "night". However, being based on kitsune, their actual personalities are more reclusive, protective and prone to pranks. Just...don't mess with their family.
 * Digimon Frontier once has a lecture about how dark and light are opposite, but neither is inherently evil, resulting from the heroes encountering some strange but harmless creatures on the Dark Continent. This foreshadows
 * In Digimon Tamers, this was the case post-Heel Face Turn with Beelzebumon. Even though he was still a demon and had the element of darkness, the fact that he wasn't actually evil was part of what triggered his transformation into Blast Mode. This was backed up by a conversation between him as Impmon and Jianliang's sensei, who said he didn't sense an evil heart within him. The same applies to the Beelzebumon of Digimon Xros Wars, who was an outright noble heroic figure with an unfortunate history.
 * WereGarurumon can be counted simply by being a werewolf with a skull on his pants. He first debuted in the Nightmare Soldiers Pendulum virtual pet, which consisted of darkness and/or zombie-themed Digimon, but is of the Vaccine-types and is one of the main characters of Digimon Adventure.
 * Agunimon and his line also belong to the Nightmare Soldiers family.
 * in Digimon Savers post-Heel Face Turn.
 * Dobermon and Alice in Digimon Tamers.
 * The Gantz team is always dressed in black, but are mostly the good ones (or at least better than the bad guys).
 * We don't know for sure whether the aliens are all bad, though. Most of them are just trying to go about their everyday lives when they run afoul of the Gantz Team. Hell, the Oni aliens were fully functioning members of society.
 * Deshwitat, the main character from the Rebirth Manhwa is a dangerous Dark Power-loaded half-vampire bent on killing Kalutika, The God of Light because
 * While it is questionable as to how closely Alucard holds up to this trope, given that he's not exactly heroic, this is definetly played straight with Seras Victoria. Sure, she dresses in bright colors, but she's a vampire, and yet she values virtue and morality more than most other Hellsing operatives, even Integra Hellsing. Not that it stopped her from  But she is against killing people. Except the Major.
 * The main character of 666 Satan is part demon, has a black and white motif with more emphasis, and constantly says that his goal is to rule the world. However, throughout the story he ends up doing more good than evil, accomplishing his goals more by gaining allies and saving people.
 * Actually Zig-Zagged later on. By nature, Dark Is Evil and Light Is Good; Demonic Recipes are Complete Monsters while Angelic Recipes are good (or innocent). However, bringing all the angels OR demons together will result in The End of the World as We Know It. What's more, human morality doesn't affect Recipe compatibility.
 * Out of the three supreme Oni siblings in Hell Teacher Nube, only middle brother Sekki is irredeemably evil. Baki and Minki start out this way, but are quickly brought to the side of good by Nube and remain heroic characters throughout. Similarly, a Western-style devil summoned by a witch (and fellow teacher at Nube's school) is actually a very nice guy, and Yukime's schoolmates at the Youkai High are great people, except for being, you know, horrible demons. (Ironically, at least one god is demonstrably evil.)
 * Evangeline of Mahou Sensei Negima uses Dark magic, but she's more of a Noble Demon. Also two of the team members are part Demon, but are perfectly trustworthy (and probably some of the more honest of characters).
 * Later on, Negi but he's still the same fussy and sweet-natured boy.
 * Not that choosing dark magic is without moral dilemmas. While dark is not inherently evil, it tends to intensify and magnify negative emotions (hate, anger) which can lead to evil. Negi very nearly succumbed in a recent chapter, and Rakan, the man who presented him with the choice between choosing dark or light magic, worries that Negi's inherent darkness (anger, thirst for revenge for his village, guilt), supplemented by the dark technique Negi learned, may lead him to be lost in darkness.
 * Also, turns out that because he's been using the technique, now he's . Of course, in Negima,.
 * Before that, you've got Takane D. Goodman, a Mahora mage who uses shadow spears in combat...when she gets a chance to.
 * Fran Madaraki of Franken Fran is a Cute Frankenstein's Monster. She has almost No Social Skills, and her day-to-day life can be best described as "macabre". But she's a brilliant surgeon (if unorthodox) whose entire existence is defined by helping people as best she can. Her servants also count - they look like the cast of a Universal Studios horror movie, but given they all recoil in terror from an actual horror movie...
 * Unfortunately, while Fran does mean well, the results of her experiments tend to end very badly for the people she is "helping" (although, in many cases, they did have it coming).
 * Her sister Veronica could also count. Sure, she loves to kill, but she does it as quickly as possible so they don't suffer. Of course, when she first see the outcome of a "Fran-periment", she does what any sane person would do: scream.
 * What about Skull Knight and Guts (known as the Black Swordsman) in Berserk? Sure, Guts isn't exactly by-the-book good, but he's willing to fight the real evil until the final consequences (to himself) must be worth something, not counting he's actually a Jerk with a Heart of Gold. The other is literally a Skeleton, as his name implies, and is frequently confused with Death itself, but is probably the most by-the-book Knight in Shining Armor in the whole universe of Berserk.
 * To be fair, in the world of Berserk, Guts is pretty much a Knight in Shining Armor when compared to everyone else in the world. In a less Crapsack World, he'd be an Anti-Hero at best, but considering where exactly he lives, he is Sir frickin' Gawain.
 * Angel Sanctuary has about all the main cast dressed in black robes and the like. And a lot of the good guys are demons or at least argueably non-holy creatures.
 * The title character of Yu-Gi-Oh!! often uses the Black Magician card. There's also the Shadow Games; they often have a harsh penalty for the loser, but the one who initiates a Shadow Game must either make the rules completely fair or put himself at a disadvantage. Plus, they're generally only invoked against or by bad people anyway.
 * They go one further in Yu-Gi-Oh! GX, where Judai's is actually not that evil (nor, surprisingly, is the third season's antagonist,.
 * Juudai was never corrupted by the Light. Nor was Haou. Juudai chose to become evil in order to fight evil, which was a big misunderstanding, nothing more. There's no mention anywhere in all of GX of Juudai or Haou being corrupted by the Light.
 * That said, however, while both of Darkness' hosts were relatively nice people when they weren't trying to either set fire to Judai's friends or
 * In the manga version of GX, the headmistress of the Osiris Dorm is Midori Hibiki, a sweet, kind, and helpful teacher; her deck as a duelist, however, uses sinister-looking Darklords, Fallen Angels named after Biblical demons like Asmodeus and Superbia. Ironically, the character who becomes her hated enemy is the villain who cursed her brother and put him in a coma, Reggie MacKenzie, whose goddess-themed deck makes her a clear example of Light Is Not Good.
 * Cardcaptor Sakura has both a "Shadow" card and a "The Dark" card, neither of which are evil.
 * The shinigami in Death Note look grotesque and kill humans to prolong their own lives. Despite this, they're a far cry from card-carrying villains. Most of them are morally neutral and easy to get along with. A few shinigami even fall in love with a human and risk their lives to protect her. On the other hand, they still kill humans (and gain the most if a human had a long life ahead of them) and Ryuk is arguably the evilest character in Death Note since he sets off all the terrible things that happen in Death Note For the Evulz.
 * Of course, in Death Note the protagonist is a Knight Templar who's ironically named Light.
 * The heroic Exorcists of D.Gray-man are part of the Black Order. Despite the name and generally ominous, gloomy labyrinths that make up its headquarters, it's a good organization full of generally friendly people.
 * However, the standard "dark = evil" is played straight in that the Akuma are made of "dark matter" and the Innocence is "white". Also, the evil Noah all have Dark Skin, well, most of the time anyway. And the only exorcist to go bad so far was Suman DARK.
 * But wasn't it the WHITE innocence that MADE him go "bad" and turn him into a...a...let's just leave it at that. Not to mention, all of the good Exorcists WEAR black.
 * In order to save Deedlit (and, indeed, all of Lodoss) in Record of Lodoss War, Parn had to wield both the Holy Sword as well as the Soulcrusher, symbolizing the necessary balance between Light and Dark.
 * Even more so: The 'Dark Knight' Ashram may appear to be utterly evil but indeed only seeks for a place for his people to live in peace (other than a cursed island, if possible). And his lover Pirotess isn't that much more evil than Deedlit, just less pure.
 * Despite the name, the Lord of Nightmares, from The Slayers, is not evil. She is, however, extremely powerful and dangerous, and the spells that draw on her power both count as Dangerous Forbidden Techniques.
 * Lampshaded in that a lot of characters do think that She is evil and the revelation that She is not is a pretty big reveal.
 * The Lord of Nightmares is more of a beyond morality kind of character. Her actions are thus not subject to being called good or evil. I suppose, however, if you want to look at it from the narrow-minded short term mortal view, that she chose not to unmake the world when she could have, to have been rather nice of her.
 * A truer example would probably be the Overworlders in Try - despite the dark scary armour and orignally worrying goal of summoning the Dark Lord of their own world (Darkstar), they actually serve the gods of their world and want to summon Darkstar to destroy him after he's merged with their god, gone berserk, and ravaged their own world.
 * That said, they range in "goodness," from Almayce  who shows concern for the protagonists' world, to the more ruthless Erulogos, who's willing to let Darkstar wreak havoc on it if it means getting him out of their world.
 * The demons of Yu Yu Hakusho go all over the morality spectrum. While we have demons like Suzaku and Yomi that want to take over the human world and treat us as cattle, we also have outright good demons like Kurama, Yukina, and Raizen. In fact, his learning that not all demons were evil was half the reason for Sensui turning into a Nietzsche Wannabe. The other half was learning that Humans Are the Real Monsters.
 * It gets even better. At the end of the manga, . When that gets revealed, the barrier between the human world and demon world gets removed, and its shown that both worlds are slowly but surely intermingling with each other in peace.
 * Which is, not to put too fine a point on it, bullshit, which contradicts common sense and just about everything we've seen about demon culture for the entire series. Togashi was just being weird to give his characters commuting abilities without an Inferred Holocaust.
 * Enma being a jerk is completely believable, though. Vive le Resistance! Except not the anti-Koenma Resistance of fanatics with the Space Laser and the turbans. Vive the coup?
 * Even the ones who eat us are spectrumed. Yomi is exquisitely civilized (in a brutal demon lord way) but just does not care about us and things like 'rights'; Mukuro is gruff and does exactly as she pleases, which happens to include eating the meat she likes best; Yusuke's bald monk buddies can't apparently live on anything else and if they'd starved themselves while Raizen was busy doing so then they wouldn't have been able to take care of him...
 * It is unclear whether any of these guys stop eating people before the end, laws or no laws, but Hokushin & co. are still healthy. Yusuke doesn't seem to care anymore.
 * In Naruto, the Tailed Beasts were very feared and hated by humans due to their freakish appearence and immense size and power. The villages have tried many times to obtain them as a display of military power and to prevent them from roaming free and presumably destroying human-occupied land. Legend says that they are born from malevolence and feed off of it, but recent chapters say otherwise.
 * Subverted in Sayonara, Zetsubou-sensei with Mayo Mitama. She really is as evil as she looks, but everyone else simply assumes that she's misunderstood. Basically, she takes full advantage of those savvy in this trope.
 * GaoGaiGar FINAL takes this trope home and cuddles it. GaoGaiGar was always black, so the OVA pits it against the clinical-white Palparepa, who has an A God Am I complex the size of the sun. Then, just to drive the point home, it depicts freeze-frames in the battle as between a white angel and a black demon. FINAL also created the final pair of Dragon Twins, KouRyu and AnRyu, who represent light and dark respectively, and combine into TenRyuJin (that's Heaven Dragon God in kanji).
 * Genesic GaoGaiGar, the main mecha of the GaoGaiGar FINAL OVA and the true form of GaoGaiGar itself, is the literal God of Destruction, whose purpose to 'bring hope of a new start from zero'.
 * Hei, a contractor with the nickname "The Black Shinigami" in Darker than Black, is probably the most humane of all the contractors despite his morbid reputation and a love for black clothing. Bonus points: "Hei" means "black".
 * Hayate Yagami of Magical Girl Lyrical Nanoha. The Queen of the Night Sky and mistress of the Book of Darkness, she has six black wings, a mostly black motif, and her signature spell is a Sphere of Destruction made of pure darkness called Diabolic Emission. She is also the boss of the heroes and one of the nicest people you could ever meet. (Except, of course, when you're a well-developed female, which means she will get her hands on you by any means possible.)
 * The demons in SHUFFLE! are only demons in name. They're pretty much amiable people with long elven ears. Nerine and her Hot Shoujo Dad Forbessi exemplifies this well enough, these demons seems to be less rambunctious than the Gods' side (which consists a Genki Girl and a Bumbling Dad).
 * History's Strongest Disciple Kenichi has "Dou"-type martial arts, which are powered by rage and aggression (in contrast to "Sei"-type, which are more about skill and precision). It is stated that many practitioners of Dou martial arts are most likely to walk the path of destruction. However, Dou-type fighting in itself isn't regarded as evil, and Dou users who are gentle by nature (including two of Kenichi's masters and his love interest) don't usually fall to that path.
 * A more literal example would be in the opening of season 2, where Kenichi's uniform is dark gray, almost black, and Odin's apparel is pure white.
 * Umehito Nekozawa from Ouran High School Host Club is a fairly nice person who just happens to be allergic to any light that's not candlelight.
 * The Black Knights of Code Geass.
 * And then there's C.C., a rather creepy Mysterious Waif who is also a powerful witch. She isn't an especially nice person, but she's never intentionally harmful.
 * Lelouch himself, despite his numerous faults, is still considered the "Hero" when compared to the machinations of many of his opponents.
 * Just look at him! An Eerie Pale-Skinned Brunette, who leads a double life, made a contract with a witch to give him a power to make everyone do his bidding that gives him a Red Eye, while his clothes are either an all-black uniform or a Malevolent Masked Man(with Spikes of Villainy) and an Ominous Opera Cape (High Collar of Doom included)and a suit that is reminiscent of a royal. Meanwhile, his Evil Counterparts, Mao And Schneizel are albino and blond.
 * The Black Knights as a whole take this Up to Eleven, especially if the viewer has seen Gundam prior to watching the show. Let's see, they wear black uniforms with Face Concealing visors, pilot Cyber Cyclopses which are also colored black, have a leader who plays about half of the villain fashion tropes and not intrinsically evil though generally reserved for villain mannerism tropes in the book, have an Ace Pilot in a fast moving red mecha who is The Rival to a 17 year old kid who Fell into the Cockpit of a Super Prototype...
 * In Sailor Moon, Hotaru may be Sailor Saturn, the Soldier of Destruction, but she isn't evil. In fact, she's very shy and sweet, and even though she's possessed when we first meet her, it's not her fault at all.
 * Tuxedo Mask could also fit to some extent. Particularly well noted in his former life as a prince, in which he wore dark clothes that are more usually attributed to villains; contrasts quite nicely with the princess's white dress.
 * Pluto is also a decent example. Not many realize that being the Guardian of the Underworld is part of her duties, as it plays second fiddle to her dealings with Time. The personal color on her Sailor Fuku is also black and her skin is shown to be darker then the others.
 * The manga version of Chrono Crusade toys with this. Chrono is always known as a Noble Demon, and he's actually a very sweet person with good intentions, despite being a demon. The rest of the demons seem very evil at first, but Aion is actually a Well-Intentioned Extremist that has simply come to believe the only way to "fix" the world . He's actually a very nice guy...besides the whole evil plan thing. In fact, all the Sinners have far too complicated motivations to be called "evil". And even the rest of the demons are The anime version, however, plays most demons as far less complex.
 * Note that Aion's character design is 'light' themed and he generally wears white, and that YMMV on his character, since friend and brother and Well-Intentioned Extremist and what have you he is absolutely a Magnificent Bastard sadist on top of everything else, even in the manga. In the anime he's
 * D.N.Angel actually has a character named Dark—who, you guessed it, isn't evil, despite being a Phantom Thief with black wings.
 * On the other hand, his light-looking counterpart Krad is really quite evil.
 * The Aswad from Mai-Otome are considered enemies of the Otomes because they dress in dark colors and are able to control Slaves, just like the Schwarz. However, when Arika and Mashiro take refuge in one of their settlements out in the Black Valley, they learn by observing the Aswad's leader, Midori, that they aren't quite as evil or scary as she first believes.
 * The Shinigami from Bleach all dress in black, and while many of them are morally ambiguous (or, in at least one case, downright evil) the majority are decent people...particularly compared to the white-clad soul eating death monsters on the other team. Most especially Ichigo, whose most powerful form is dressed in solid black, with a solid black sword, and fires off huge blasts of darkness as his most powerful attack...and he's the main hero.
 * "Titty" Kubo has stated that the white=death/black=life theme in Japan is in full-effect in Bleach. Fact: The manga was originally going to be titled "White" because of the prevalent theme of death (early, anyway), but Kubo scratched that and used "Bleach" instead because it held the same general idea and sounded a lot cooler.
 * Kubo really likes to lay on the solid black tones, too.
 * Kukuri in Mahoujin Guru Guru dresses in black robes, carries a staff with an eye on it, and is described as a "Dark Elemental." Her magic involves demon-summoning and is considered dark magic. However, while possessing many traits of the Black Magician Girl, Kukuri's personality is closer to that of the White Magician Girl. There is also a Dark Society of black magic practitioners who are allies of the heroes against the demon lord Giri.
 * The Japanese superhero Golden Bat pretty much personifies the trope.
 * In +Anima, Cooro can't help the fact that he has crow's wings, nor that everyone therefore assumes he's the angel of death. It just...happened.
 * Sacrifar, the ninth form of Rave Master's Ten Commandments sword is a Darkness-aligned blade that increases Haru's aggression. When Haru first tried to use it in a battle, its influence began taking over his body and mind. Later, however, it is revealed that this wasn't because the sword was evil, but was due to the fact that the Ten Commandments was forged specifically for Haru's predecessor, thus Haru could not wield it properly. Presumably Haru is able to use it safely after he gets a sword of his very own, but he never used it again after that incident.
 * Duo Maxwell from Gundam Wing wears black (including a leather jacket in The Movie) and uses the nickname "Shinigami" to refer to both himself and his Gundam, Deathscythe, which is also black, wields a beam scythe, and even gets shield-like bat wings in its Mid-Season Upgrade. Personality-wise, however, he's the goofy, cheerful, flirtatious Lancer of the group (though not without his Hidden Depths).
 * He's the only actual cynic they've got.
 * He's also the sanest guy they've got.
 * Ogami of Code Breaker has dark hair, dark clothes, a dark glove, and uses his powers to burn people to death on a regular basis. He's also very much a good guy, going to great lengths to protect his friends and allies.
 * Mixing this up a bit with Light Is Not Good, Ogami's sempai is very sinister and is usually seen reading bondage H-manga, but he can control light (in the form of a shibari rope, naturally) and is also on the side of good.
 * Karasu in Noein looks kind of creepy—long white hair, black robes, a perpetually snarly face, always angry, and he's played by Crispin Freeman...but he's, wanting to protect Haruka. His counterpart Noein is a Well-Intentioned Extremist however,
 * Some of the chimearas of Fullmetal Alchemist, especially Zanpano and Jelso, whose "beast modes" are pretty ugly; the same probably applies to Alphonse Elric when his soul was attached to the armour as it is presently. Of course, this being a world where the bad guys are homunculi, Dark Is Evil is played fairly straight, and so is Light Is Not Good.
 * In the manga and Brotherhood, anyway. It was rather more ambiguous in the first series; in particular, Lust dropped her Card-Carrying Villain status.
 * Greed takes anime!Lust's place in the manga as Homunculi-with-a-(hidden) heart.
 * In the manga, Hohenheim is quick to remind us the he's a monster; he still bends all his efforts toward saving people and acts jolly and clueless most of the time. His eldest son's original form, aped by his eldest grandson, is the strongest Dark Is Evil in the series—but it is in turn just a piece of the darkness that exists beyond the Gate. Which appears to be pretty much hell.
 * The 'dark demon blade' of the Nakatsukasa family in Soul Eater fits this one. While originally it appeared to be something of an Evil Weapon of Living Shadows, when used by Tsubaki and Black Star it has turned out to be formidable for the protagonists. Arguably, the nature of chaos/insanity in the series where it and order take the place of 'good versus evil'. The shinigami too, naturally, seeing as Death leads the good guys and isn't your most creepy-looking of Grim Reapers.
 * Yakko from Akazukin Chacha has dark blue hair, wears black and purple and relies on dark alchemy, and she is one of the silliest characters in the show.
 * Michiru and Kaoru of Futari wa Pretty Cure Splash Star, who continue to use their powers as warriors of the Dark Fall, even after their Heel Face Turn.
 * Celty from Durarara!! is a Dullahan; a headless, Unseelie fae which is heavily associated with death, who rides a possessed black motorcycle, has black mist flowing from her neck and can do all sorts of interesting things with shadows. She's also one of the nicest, friendliest and most kind hearted people you could ever wish to meet. Her roommate, Shinra, even lampshades it, pointing out the forces of darkness don't appear to be evil so much as they're just Tsundere.
 * Black Jack, while morally ambiguous, is nonetheless a life-saving hero who dresses in a black suit and black opera cape and has mostly black hair. His archenemy Kiriko is an overenthusiastic euthanasia doctor and has eerie white hair.
 * Kageyama of Fairy Tail is proof that just because you are in a Dark Guild does not mean you are completely evil. Definately misguided, but not totally evil.
 * Bonus points for him, since he uses magic that lets him manipulate his own shadow (most notably turning it into a bunch of snakes), and the fact that we see him in the background of the Fantasai parade, along with another member of the former Dark Guild.
 * Frau from 07-Ghost is probably one of the most literal forms of this trope. As he and all the other ghosts for that matter are worshiped as the protectors of the church, even though they all take the form of their enemy, the feared death god Verloren. Frau even wields Verlorens Syth as a weapon and
 * Father Abel Nightroad of Trinity Blood may have white hair, but he wears black habitually, and in his Cruznik form he has dark skin and black wings. His homicidal, genocidal, brother Cain wears white, has blond hair, and in Cruznik form has white wings and light skin.
 * Humorously Lampshaded at the end of Vampire Hunter D: Bloodlust, when D's hand-parasite quips to very grim, gothic D:


 * Yu-Gi-Oh! likes this. Yugi, the hero of the first series, runs a Dark Magician deck. in Yu-Gi-Oh! 5D's, co-Lancers Jack and Crow run Archfiend and Blackwing decks respectively. The former has Red Dragon Archfiend (Red Demon's Dragon) as an ace monster, while the latter is centered around the Dark-typed Blackwing monsters.
 * Can't remember it's name, but this occurs in a surprisingly cute H-Manga about a girl that's feared due to her resemblance to Samara/Sadako, so much so that even her non-Slasher Smile creeps them out. When the male lead has to return to the locker room to get his clothes, he catches her rubbing one out while smelling said clothes with her eyes finally shown as she gives an Anguished Declaration of Love. He promises that he'll masturbate in kind to her before bed before going on to have sex with her in the courtyard to prove how much he loves her and isn't afraid of showing it though are surprised to not be caught. From then on, they become an open couple with her hair clipped back.
 * Porunga from Dragonball Z one of the wish-granting dragons. He is a demonic, frightening-looking beast, but he's far nicer than even most regular dragons. When the heroes wished for everyone on Earth to be resurrected after Buu killed them, he went the extra mile and rebuilt all their cities and buildings free of charge.


 * Back to
