[[caption-width-right:350:A ''fantastic'' color for a ''fantastic'' family!]]

->''"In ancient Hyrule, this garment could only be worn by one who had earned the respect of the royal family. It's dyed in vibrant blue."''
-->-- '''Description for the Tunic of Memories''', ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom''

[[blue:Blue]], the color of [[HeavenlyBlue the heavens]], the color of [[KnightInShiningArmor a knight's armor]]. The color of [[HealItWithWater life]]-giving [[WaterIsBlue water]], and [[InnocentBlueEyes an innocent child's eyes]]. The color of a [[NobleProfession policeman's uniform]], and, in the US and Britain, the color of anti-[[DirtyCommies communist]] soldiers and [[CaptainPatriotic patriots]]. For all these reasons and more, the color blue has an association with goodness, such that a blue ColorMotif is often a visual shorthand for TheHero or the good guys.

Often times this goes along with a more old-fashioned or cerebral type of heroism. While [[RedIsHeroic red-clad heroes]] tend to be HotBlooded, since BlueIsCalm blue heroes tend to be more disciplined and reserved, whether due to a [[TheFettered code of honor]], more [[ExperiencedProtagonist training]], a focus on [[TheSmartGuy brains and strategy]], or simply a [[MellowFellow calmer personality]]. It's common for red- and blue-themed heroes to be paired together as TheHero and TheLancer in a RedOniBlueOni setup.

There are a few requirements for this trope:

'''Must be a hero:'''
* The character or group of characters must actively fight against evil. Just being a NiceGuy is not enough. This also excludes works with NoAntagonist.
* If only one character is associated with blue, they should be TheLeader of a heroic team or a main character. When TheTeam has one supporting member wearing blue, you're looking at RainbowMotif, ColorCodedElements, or ColorCodedCharacters instead.

'''Must be consistent:'''
* Blue should be a consistent part of the character design, whether for the SuperheroTeamUniform or for an individual. If a character has an UnlimitedWardrobe and wears blue one time, that's not an example, unless the blue appears at an especially symbolic moment such as a climactic confrontation or promotional art.
* Blue should have a consistent association with heroism throughout the work. If Alice the Hero, Bob the villain, and Carol the HeelFaceRevolvingDoor are all associated with blue, that's not an example.

See also BlueMeansSmartOne, TrueBlueFemininity and PinkGirlBlueBoy for other blue tropes, and PrimaryColorChampion when blue, red, and yellow are all used together to signify heroism. Also see ColorCodedArmies, ColorCodedCharacters, and ColorCodedWizardry for other uses of contrasting character colors.

Overlaps with GoodColorsEvilColors when paired with an antagonist in a contrasting color (often [[RedAndBlackAndEvilAllOver red and black]] or [[SecondaryColorNemesis a secondary color]]). Also compare and contrast MysteriousPurple for people with less defined and often obscured allegiances and moral leanings.

See the Analysis page for discussion of real-life reasons for this trope.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Manga/BlueExorcist'' has this trope right on the title, with Rin Okumura being the AntiAntiChrist who becomes an exorcist and battles his father [[ArchNemesisDad Satan]] while having a strong affinity with [[TechnicolorFire blue fire]] that [[WreathedInFlames engulfs him]] whenever he unleashes his [[KatanasAreJustBetter sword]].
** Played with in regards of the blue flame, considering that it's always associated with Satan and feared by everyone, which is why Rin is forced to not show his blue flames early on. Regardless, this doesn't change the fact that Rin is still a heroic guy.
* ''Manga/DeathNote'' has L as a HeroAntagonist version of this trope. GreatDetective L is usually associated with the blue color, while VillainProtagonist and serial killer Light Yagami is associated with red. This is usually represented in the lighting they get.
* Emiya Shirou, the main hero of the ''VisualNovel/FateStayNight'' franchise, wears a lot of blue during the three main routes of their story. This signifies his own WideEyedIdealist nature compared to the pragmatism of his enemies. This contrasts with his red-clad archenemy [[spoiler:and future self Archer, especially in the Unlimited Blade Works route where they clash.]]
** Saber is a KnightInShiningArmor based off of Myth/KingArthur and wears a blue BattleBallgown. The Visual Novels also usually depict her attacks with blue SwordLines, as do ''Literature/FateZero'', and the remake of the original ''Stay Night''. In both ''[=Fate/zero=]'' and ''[=Fate/Stay Night=]'' she is the Servant of the protagonist of the story, and together they face off against a number of more sinister or less idealistic foes to take possession of the Holy Grail. In ''Zero'' her knightly idealism [[TeethClenchedTeamwork frequently clashes]] with Kiritsugu's utilitarian anti-heroism.
* ''Manga/JoJosBizarreAdventure'':
** ''[[Manga/JojosBizarreAdventurePhantomBlood Phantom Blood]]'': Jonathan Joestar is the kindhearted and noble hero of the series and the story's original hero. During the final arc of ''Phantom Blood'', he wears a blue tank top.
** ''[[Manga/JojosBizarreAdventureStardustCrusaders Stardust Crusaders]]'': The main hero, Jotaro Kujo, wears blue clothing.
* Shinji Ikari, the monster-fighting main protagonist from ''Anime/NeonGenesisEvangelion'', whose pilot suit is blue in contrast with the other pilots (white for Rei, red for Asuka, black for Kaworu, and pink for Mari).
* Most iterations of ''Anime/PrettyCure'' (sans the [[Anime/FutariWaPrettyCure first three]] [[Anime/FutariWaPrettyCureSplashStar seasons]] and ''Anime/MahoGirlsPrecure'') star a blue-clad heroine. She is typically TheSmartGirl of the team, has [[MakingASplash water-based powers]], and is a calm, mature character to contrast the PinkHeroine leader.
** ''Anime/YesPrettyCure5'' and ''Anime/YesPrettyCure5GoGo'': Cure Aqua, who has blue hair and wears a blue dress and shoes, is the team's brains, and has water-based powers. She joined the team by helping them to defeat a MonsterOfTheWeek.
** ''Anime/FreshPrettyCure'': Cure Berry, who wears a blue dress and boots, is the team's KickChick.
** ''Anime/HeartcatchPrettyCure'': Cure Marine, who has blue hair and wears a blue dress, has water powers, but prefers to fight with her own fists and feet.
** ''Anime/SuitePrettyCure'': [[spoiler:Cure Beat]], a late addition to the team who wears a blue dress and boots, fights along Melody and Rhythm with her own music powers.
** ''Anime/SmilePrecure'': Cure Beauty, who has blue hair and wears a blue dress, has ice powers, and most commonly takes on [[TheDragon Joker]] in swordfights.
** ''Anime/DokiDokiPrecure'': Cure Diamond, who has blue hair, is her team's voice of reason and has ice powers. In one episode, she even gets to create a giant ice staircase, [[WesternAnimation/Frozen2013 Elsa]]-style.
** ''Anime/HappinessChargePrettyCure'': Cure Princess, who has blue pigtails and wears a blue dress and leggings, is a DanceBattler and has wind powers.
** ''Anime/GoPrincessPrettyCure'': Cure Mermaid, who has blue ocean hair and a blue dress, has water powers, and gets to fight Twilight directly.
** ''Anime/KiraKiraPrecureALaMode'': Cure Gelato, who has blue ''everything'' minus skin, has powers based on the lion, as well as ice powers.
** ''Anime/HugttoPrettyCure'': Cure Ange, who has blue hair, has wind powers and wants to help others by becoming a doctor.
** ''Anime/HealinGoodPrettyCure'': Cure Fontaine, who has blue hair and wears blue shoes, has water powers and also wants to become a doctor.
** ''Anime/HirogaruSkyPrettyCure'': Cure Sky, who has blue hair and wears a blue dress, is the first blue-themed leader, and comes with wind power, SuperStrength, and super high jumps.
* ''Anime/LaSeineNoHoshi'': Simone's hair bow and hat are blue, and as a superheroine she wears a blue cap with a white star.
* Inverted in ''Anime/VoltesV''. Inverted. Heinel wears a huge blue coat that has a collar resembling a snowflake, and his list of crimes include, but are not limited to: invasion, mass murder, slavery, abuse of power, unethical experimentation, animal cruelty, mass genocide, holding hostages, kidnapping and torture. However, in his disturbed mind, he believes he's heroic for all this.
* ''Franchise/YuGiOh'':
** ''[[Anime/YuGiOh Yu-Gi-Oh!: Duel Monsters]]'': Yugi is the main hero of the series. His primary outfit includes a blue outfit and blue pants. Yugi regularly saves the world by defeating villains in a magic card game.

[[/folder]]

[[folder:Arts]]
* Creator/AlexandreCabanel's ''Art/TheFallenAngel'':
** The non-fallen angels in the background are blue-tinted. {{Justified|Trope}} since they are far away and, thus, suffer from [[https://en.wikipedia.org/wiki/Aerial_perspective atmospheric distortion]].
** [[PlayingWithATrope Played with]] Lucifer's wings; whatever white is left on them has blue lightning: -- most of his left wing and the insides of his right wing. However, there are small blue tinges on the borders of the blackened feathers.
%%There are several figures in blue in this painting. Please clarify whether the associations are consistent.* One of the central figures in [[Creator/RaphaelSanzio Raphael]]'s ''Art/TheSchoolOfAthens'', Aristotle, is cloaked in a vibrant blue that marks who '''the''' Philosopher is in this assembly of great and holy minds.
* Blue is also the signature color in Christian art for Mary, mother of God and one of the most holy figures, part because blue paint was very expensive before chemical dyes (made by ground-up lapis stones), and artists wanted to make sure the top-shelf paint was reserved for her.
[[/folder]]

[[folder:Asian Animation]]
* ''Animation/PleasantGoatAndBigBigWolf'': Weslie is often the one to learn Wolffy's plans and put an end to them, and he wears a blue collar with a bell on it and is associated with the color blue in later seasons.
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/{{Aquaman}}'' often has its heroic characters wear blue.
** The titular character wore blue in a miniseries during the 80s.
** Garth the original Aqualad, wore blue shorts originally. His depictions in the ''WesternAnimation/TeenTitans2003'' and ''WesternAnimation/YoungJustice2010'' animated shows had him wearing black and blue despite his outfit in the comics being red and black. He currently wears blue in the comics following the New 52 reboot.
** Koryak, Aquaman's half-Inuit son and sidekick during ''ComicBook/Aquaman1994'', also wore blue.
** Lorena Marquez, the second Aquagirl, wore a blue outfit.
* Despite his name, superhero ComicBook/BlackLightning's costume sports a dark blue costume with prominent bright blue trims.
* ComicBook/BlueDevil is a stuntman turned crime-fighting demon with blue skin.
* The [[ComicBook/AdamLegendOfTheBlueMarvel Blue Marvel]] wears an all-blue power suit and even uses "blue" in his superhero ''name''.
* [[Characters/MarvelComicsSteveRogers Captain America]]. Although his costume is supposed to represent the American flag, blue is by far the most prominent color. This helps to drive home his straight leadership in ''ComicBook/TheAvengers''.
* Leander from ''ComicBook/{{Democracy}}'' is The Hero of the story and he wears a blue loincloth.
* In ''ComicBook/ElseworldsFinestSupergirlAndBatgirl'', both title heroes wear blue: Characters/{{Supergirl|TheCharacter}}'s outfit is sky-blue and Characters/{{Batgirl}}'s suit is dark-blue (and her first Batgirl costume was indigo).
* The ComicBook/FantasticFour. Full stop. All four heroes wear iconic blue skin-tight jumpsuits. They started out with sky blue suits offset by black gloves and boots, under Creator/JohnByrne they got dark blue (almost black) suits with white gloves and boots, and from then on the look changed again now and then.
* ''ComicBook/{{Superman}}'':
** As part of his PrimaryColorChampion status, Characters/{{Superman|TheCharacter}}'s suit is prominently blue. Especially after the ComicBook/{{New 52}}, where he dropped the red underwear. Although the big red cape is just as prominent, the blue suit conveys more of Superman's gentle and kind nature.
** Fellow superhero Characters/{{Supergirl|TheCharacter}} wears a female version of the Superman costume. She has worn many different costumes through the decades, but they are always blue (with two exceptions: one of the Linda Danvers' outfits and her ''[[ComicBook/RedDaughterOfKrypton Red Lantern uniform]])''. In ''ComicBook/KryptonNoMore'' she wears her [[http://1.bp.blogspot.com/-H9Y7oCOe8aE/Uj9h0rzcgYI/AAAAAAAANvY/n7qeE8SV1EU/s1600/Superman3070006.jpg "hot pants" seventies blue costume]].
** Characters/{{Super|manConnerKent}}boy may be less of a boy scout than Kal-El but from his first breaths he was most interested in saving people than anything else and within his first month of life he was already risking his own life and powering through debilitating pain and injuries to help others. He wears a similar costume to Superman and Supergirl. His association with blue died down following his resurrection, however.
** Downplayed with Characters/PowerGirl, Supergirl's AlternateSelf. She wears blue gloves and boots along with a white LeotardOfPower and a red cape.
* ''ComicBook/UsagiYojimbo'': The eponymous Usagi is a [[RighteousRabbit heroic rabbit]] {{Samurai}} who wears a blue kimono.
* Characters/{{Nightwing|DickGrayson}} has been through many outfits, but the one quality that's almost always there is the color blue. He briefly went red in the ComicBook/New52, but that soon went away.
* ''ComicBook/XMen'':
** [[Characters/MarvelComicsCyclops Cyclops]] TheLeader is usually depicted in a blue (along with yellow) spandex in more modern versions.
** [[Characters/MarvelComicsBeast Beast]] with his blue fur, intelligence, and kind nature.
** In the same vein as Beast there's [[Characters/MarvelComicsNightcrawler Nightcrawler]] who has blue fur; he's such a NiceGuy he went to {{Heaven}} and came back to save his friends. Nightcrawlers's [[RidiculouslyCuteCritter little brothers]] the "''Bamfs''" are also blue thanks to him, all to the contrast Azazel Nightcrawler's ArchnemesisDad whose a BigRedDevil.
* ''ComicBook/WonderWoman'':
** The titular superhero's secret identity Diana usually wears either blue briefs or a skirt.
** [[Characters/WonderWomanAllies Nubia]] has since taken to wearing a blue outfit following her return to prominence in ''ComicBook/DCRebirth''. She wears a blue outfit in the stories that focus on her in ''[[ComicBook/DCFutureState Immortal Wonder Woman]]''.
[[/folder]]

[[folder:Fan Works]]
* ''Fanfic/AbraxasHrodvitnon'': Thor's eyes and electrical powers are blue, and he's a fierce protector of Titan. Manda has a blue coloration, and despite being a baby is already displaying noble personality traits.
* ''Fanfic/TheApprenticeTheStudentAndTheCharlatan'' features hero protagonist Nova Shine, whose coat is white, but is noted for his rather strikingly bright blue mane, tail, eyes, and magical resonance, as well as a deep blue cloak that he picks up later.
* In the ''Fanfic/AvengersOfTheRing'' series, Steve Rogers becomes known as ‘the Blue Runner’ to warriors on both sides during his time in Middle-Earth, inspiring fear in Sauron’s forces and hope for the people of Gondor.
* In ''Fanfic/BeyondHeroes: Of Sunshine and Red Lyrium,'' blue is the color most frequently associated with [[VideoGame/DragonAgeInquisition the Inquisitor]], [[VideoGame/DragonAgeII Bethany Hawke]]. She is the hero of the story and of the entire continent of Thedas, and "the sanest and sweetest person" the narrator (Varric) knows. Overlaps with TrueBlueFemininity.
* Lady Delphine is sometimes called "the woman in blue" due to her choice of dress, and she is the BigGood of New Orleans in ''[[Fanfic/{{Cinderjuice}} The Bug Princess]]''.
%%* ''Fanfic/CodeGeassColorlessMemories'': Rai has blue eyes, his Knightmare is colored blue, he wears a blue pilot suit and is actually referred to as Zero's Blue Knight InUniverse. He is often cool, calm, and intellectual in his personality. [[spoiler: and his contractor E.E has blue hair]].
* ''Fanfic/DanganronpaParadiseLost'': Protagonist Daisuke Hiyori is a KindheartedSimpleton who opposes the Killing Game out of an optimistic belief that he and the others will find a way to escape. His clothes heavily incorporate the color blue.
* ''Fanfic/LastChildOfKrypton'': In this crossover, Shinji Ikari is ''Franchise/{{Superman}}'' (both the HeroProtagonist of their own works) and wears his iconic blue outfit.
* ''Fanfic/{{Medicated}}'', Anne's frog form is light blue, just like her Calamity gem.
* ''Fanfic/TheNightUnfurls'': Alicia and the knights under her command have been defending the common folk from marauding orcs for some time. Fittingly, both her eyes and her armor are blue.
* ''Fanfic/ThePortal'' features protagonist Thomas Smith, who is transformed into a dragon with blue scales after he enters the titular portal to the Dragon Realms. He later ends up leading the fight to protect the Academy from Zobek.
%%* In ''Fanfic/WhatYouAlreadyKnow'', after Daniel Jackson acquires psychic abilities and the alias of ‘Dan’Yar’ among the Jaffa, he occasionally visits the Jaffa wearing his blue robes from Vis Uban, as the blue looks dramatic and it distinguishes him from his colleagues in the SGC.
[[/folder]]

[[folder:Films -- Animation]]
* In ''WesternAnimation/{{Aladdin}}'', the creators intentionally used the color blue to symbolize good characters (primarily Jasmine and the Genie), as opposed to red for evil (Jafar and Iago) and purple for "good, but flawed" (Aladdin, Abu). When Jafar himself becomes a genie, he's bright red.
* ''WesternAnimation/ABugsLife'': Most of the ant colony is blue and they are the sympathetic underdogs who struggling under their grasshopper oppressors. This includes the main hero, Flik, who leads them to overthrow the grasshoppers.
* ''WesternAnimation/TheIncredibles1'': Mr. Incredible is a superhero and the patriarch of the [[BadassFamily Parr family]]. He starts out wearing a black and blue suit before switching to a [[RedIsHeroic red one]] created by his friend Edna Mode.
* Played with in ''WesternAnimation/WreckItRalph''. Fix-it Felix Jr., the adorkable NiceGuy is dressed all in blue, in opposition to Ralph's red. In the ''Fix-It Felix Jr.'' game, they're TheHero and the BigBad respectively. However, the story of the movie itself is about Ralph trying to move away from his role as a villain and trying to become a hero of his own. Felix, on the other hand, moves to a [[TheLancer Lancer]] role, but without losing any of his heroic traits.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/ThreeHundredRiseOfAnEmpire'': Overlaps with RedOniBlueOni. The brainy Athenians wear blue capes in a [[AthensAndSparta stark contrast]] to the red-clad, brawnier Spartans, and serve as protagonists of the movie who fight together with the Spartans against the invading Persians.
* ''{{Film/Bright}}'': [[TheMenInBlack Agent Kandomere]] wears a stylish blue suit and literally has blue hair and serves as the story's BigGood.
* In ''Film/GodzillaKingOfTheMonsters2019'', the heroic title character's BreathWeapon is blue, and he often radiates a [[PowerGlows blue glow]], with blue lighting often foreshadowing [[BigDamnHeroes his arrival]]. The movie also emphasizes Godzilla's aquatic nature, with a lot of [[WaterIsBlue blue-tinted underwater scenes]]. Notably, when [[spoiler: he is in danger of [[PowerIncontinence melting down and destroying all of Boston]], the blue changes to a fiery, volcanic red, signaling that he is no longer a protective force, only changing back to his signature blue when he regains control]]. Likewise, Godzilla's ally Mothra has a peaceful bluish-green glow as her ColorMotif.
* ''Film/JurassicWorld'': ZigZaggingTrope with the Velociraptor [[Characters/JurassicParkVelociraptor Blue]], who is named for her distinct blue-ish color scheme. She can be as dangerous as any other raptor when provoked or hungry, but she's the closest thing the franchise has demonstrated to a truly heroic raptor, saving the main humans' lives whilst fighting the ''Indominus rex'' and the ''Indoraptor'' in either of her respective movie appearances.
* ''Film/KongSkullIsland'': James Conrad wears a blue shirt throughout the movie, and he's definitively a heroic character who leads and defends most of the cast as much as possible.
* ''Franchise/MarvelCinematicUniverse'' costumes many of its heroes in blue, while the villains almost never like this color even when their comic counterparts do:
** ''Film/IronMan2'': Black Widow wears a dark blue SpyCatsuit.
** While [[https://i.redd.it/cf55dl7ksn901.jpg the costumes]] of one of the founding Avengers, Captain America have red and white elements, blue is his signature color. However his costume in ''Film/AvengersInfinityWar'' is ''very dark'' signifying his fall from grace since ''Film/CaptainAmericaCivilWar''.
** ''Film/AvengersAgeOfUltron'': Quicksilver (who has a blue aura and clothes) subverts this for half the movie but plays it straight after his HeelFaceTurn. [[spoiler: He even makes a HeroicSacrifice.]] His sister Wanda wears red.
** ''Film/ThorRagnarok'': Loki briefly wears a blue costume to blend in better on Sakaar, but is primarily featured in it in promotional materials (posters, art books e.t.c) after ''Film/AvengersInfinityWar'' whenever they need to refer to his more redeeming side. Thus in the "Marvel Studios Visual Dictionary", he is dubbed "villain and hero" and shown [[GreenAndMean in green]] to the left (as a villain) and in blue to the right (as a hero).
** ''{{Film/Black Panther|2018}}'': The Border Tribe wear blue capes and serve as guardians for Wakanda's borders, while their leader W'Kabi served [[TheHero T'Challa]] as his [[TheLancer best friend and second-in-command]]. [[spoiler:{{Inverted|Trope}} when they all willingly side with [[BigBad Erik Killmonger]] (who also wears blue)'s genocidal scheme and become his {{mooks}} in contrast to the Dora Milage in their red attire, who serve whoever is king out of duty and clearly dislike serving Killmonger.]] This was intentional as Klaw wears blue as well; Ryan Coogler [[WordOfGod wanted]] blue to symbolize corrupt law enforcement.
** ''Film/{{Captain Marvel|2019}}'': The titular character has two costumes: the "evil" one is mostly [[GreenAndMean green]] and the "heroic" one is mostly blue with some [[PrimaryColorChampion red elements and golden decorations]].
** ''Series/{{Loki|2021}}:'' The BigBad, [[spoiler:a Variant of Kang the Conqueror]], is deprived of his signature blue colour and is merely a SecondaryColorNemesis, because unlike Marvel comics, in the MCU villains are ''not'' associated with blue.
* Probably the most iconic example in the medium is the [[LaserBlade blue lightsaber]] from the ''Franchise/StarWars'' series, usually associated with the Jedi, in contrast with red lightsabers for the Sith. With the exception of ''Film/ReturnOfTheJedi'', when green was used instead due to technical difficulties[[note]]Namely, Lucas intended to make Luke's new lightsaber blue like the last one, and it can be seen as such in one trailer. However, they changed it to green because they couldn't make the color stand out over the sky in the scene where it first appears. In addition, Mace Windu has a purple lightsaber because Creator/SamuelLJackson requested it; prior to the release of ''Attack of the Clones'', all media portrayed him with a blue lightsaber[[/note]], the main heroes have always used a blue one more often than not.
** Played with in the prequel trilogy with the laser beams from the clone army, and during the Anakin vs Obi-Wan duel. Considering how [[GoodColorsEvilColors blue is used prominently as the color of good]] in this series, this helps to establish the morally messed-up situation of the Clone Wars. Especially in the duel. General Grievous, who is absolutely evil, uses blue and green lightsabers, but this is justified by the fact that he takes these from the Jedi he kills. In fact, he has a whole collection of them.
** Subverted in a crapload of non-movie material. Lightsaber blades come in many colors, not just blue, green, or red. Yellow, orange, gold, even black and white have been seen in the novels, comics, video games, and television series.
* The Allied Nations troops fighting against a dictator in ''Film/StreetFighter'' have blue helmets and gear.
* In the ''Film/{{Tron}}'' universe, the User-believer (heroic) Programs (and protagonist Users) have bright cyan TronLines. Becomes a plot point in the [[Film/TronLegacy filmed sequel]] where [[spoiler: after being ReforgedIntoAMinion, Tron's circuitry is bright red. When he breaks free of Clu's corruption, his circuits revert to their original blue]].
* ''Film/{{Troy}}'' has the Trojans identified primarily with blue colors in contrast to the Achaeans who favor grey. Played with in that they are {{hero antagonist}}s trying to defend their homeland from conquering invaders, that just so happened to be our protagonists.
* ''Film/XMenFilmSeries'': Blue is commonly tied to gentleness, tranquility, and intelligence, which are the hallmarks of Professor Charles Xavier -- the franchise's BigGood -- so naturally it's part of his ColorMotif. Fittingly for a man with an [[InTouchWithHisFeminineSide androgynous disposition]], blue is also linked to [[PinkGirlBlueBoy masculinity]] ''and'' [[TrueBlueFemininity femininity]]; his parental authority is rooted in the blend of his TeamDad and TeamMom aspects. In his [[Film/XMen1 very first on-screen appearance]], he wears a blue suit. In ''Film/XMenFirstClass'', Charles is introduced as a scholarly kid in blue-and-white pajamas whose instinct is to be charitable towards a starving mutant girl, laying the foundation of his future ascent into an AllLovingHero and a GuileHero. As an adult, blue is routinely incorporated into his apparel, and he's the AllegoricalCharacter for serenity. In ''Film/XMenDaysOfFuturePast'', his past self is subjected to a PaletteSwap that marks the return of his familiar blues and greys to designate that he has taken up the mantle of being a hero again. In ''Film/XMenApocalypse'', he's only garbed in blue after he concludes his transition from a schoolteacher to a leader of mutantkind.

[[folder:Literature]]
* The sword Sting from ''Literature/TheHobbit'' and ''Literature/TheLordOfTheRings'', which glows blue when orcs are nearby. It was wielded by the main heroes of both books. And of course, this was carried over to the [[Film/TheLordOfTheRings film]] [[Film/TheHobbit adaptations]].
** In ''Literature/TheSilmarillion'' this association is also present: Blue is strongly associated with the more heroic faction of the Noldor led by Fingolfin. It is also contrasted with [[AntiHero Fëanor's]] scarlet. Although, the color most closely associated with heroes throughout the Legendarium is actually green: from the Ring of Barahir to the Elessar and Faramir's Ranger uniform.
* ''Literature/TheStormlightArchive'':
** The [[ThePaladin Windrunner]] [[KnightInShiningArmor Radiants]] have blue TronLines on their armor and weapons, and their eyes turn blue if they've used their powers recently.
** House Kholin, the most heroic of the ten Alethi princedoms, has blue and silver as their colors.

[[folder:Live-Action TV]]
* ''Series/AceLightning'': The Lightning Knights, interdimensional superheroes and guardians of the Sixth Dimension, all wear blue jackets, and their leader Ace Lightning also shoots blue lightning.
* ''Series/LazyTown'': Sportacus' outfit is mostly blue, and he's the official defender of [=LazyTown=] and its people.
* ''Franchise/PowerRangers''/''Franchise/SuperSentai'': One constant, no matter which colors compose a team of Rangers, is that there will always be a Blue Ranger on the team.[[note]] With the exception of the [[Series/KaitouSentaiLupinrangerVsKeisatsuSentaiPatranger Patrangers]], which consist of only a red, green, and pink rangers.[[/note]]
* ''Franchise/StarTrek'': TheFederation's flag and shield uses blue (mostly because is based on the United Nations flag) and blue color is generally used to represent Federation territory in maps and graphics.
[[/folder]]

%%[[folder:Mythology and Religion]]
%%* The Virgin Mary, Mother of God and a highly revered figure in Catholicism, is typically seen in blue in apparitions. Our Lady of Lourdes (1858) appeared to Bernadette wearing a simple gown and mantle of white with a blue sash. Our Lady of Guadalupe (1531) appeared to Juan Diego wearing a gown of rose and a mantle of blue with gold stars. Our Lady of Pontmain (1871) had a loose-fitting dark blue dress with no sash and gold stars. Blue has been a color associated with royalty, peace, and nature.
%%[[/folder]]

[[folder:Professional Wrestling]]
* El Phantasmo of Wrestling/NewJapanProWrestling notably began donning primarily blue clothing (complete with flashing blue lights on his jacket, and blue entrance text) when he [[HesBack made his return to the ring]] after being expelled from Wrestling/BulletClub on David Finlay's orders--leading to him being framed as a rebellious antihero out to end Bullet Club's reign of terror. Shortly after, the color motif was further solidified when he joined forces with his former Bullet Club stablemates in the Wrestling/GuerrillasOfDestiny, and formed a tag team with G.o.D. member Hikuleo--who also began donning blue ring gear to match.
[[/folder]]

[[folder:Tabletop Games]]
* In ''TabletopGame/{{Warhammer 40000}}'':
** The Ultramarines, lauded as the most honorable of Space Marine Chapters, have -- guess -- ultramarine shade of blue as their primary color.
** Inverted with Tzeentch, whose main color is blue and who's a SmugSnake-esque GodOfEvil.
** The World Eaters, now feared as a force of AxCrazy BloodKnight berserkers, used to be gray-blue before their FaceHeelTurn. Their armor is now entirely red and brass, the colors of the Blood God Khorne. In-universe, it's rumored to symbolize or even ''be'' the blood of their victims that they never washed off.
** The [[Literature/SpaceWolf Space Wolves]], among the most heroic ([[ValuesResonance by modern standards]]) Chapters, have armor that's somewhere between light blue and grey.

%%Administrivia/PartialContextExample* ''Theatre/{{Hamilton}}'': The Continental Army that the protagonists belong to wears blue uniforms with tan accents, while their enemies the Redcoats wear, well, red.
%%[[/folder]]

[[folder:Video Games]]
* ''VideoGame/AMCSquad'': Several of the AMC Squad's agents wear blue or have at least one blue accessory on their person, and are some of the more heroic characters in the game. Most prominent are [[TheEngineer Micky C]], [[CatFolk Snowfall]], and [[TheAce Jane Ashford]], who all wear blue suits of PoweredArmor. [[spoiler:To a lesser extent, James after he gets a blue [[ArtificialLimbs bionic arm]] at the start of Episode 3]].
* ''VideoGame/ANNOMutationem'': Ann, the protagonist, primarily wears a casual blue outfit. When in combat, she has a combat suit that's also dark blue.

* ''VideoGame/CastleInTheDarkness'': The protagonist is a knight in bright blue armour out to save the Kingdom of Alexandria from monsters.
* ''VideoGame/DeadOrAlive'': Kasumi is the main protagonist of the games. She is a heroic {{Ninja}} dressed in blue who opposes the machinations of the evil DOATEC organization.
* ''VideoGame/DevilMayCry'': Nero, the main hero of ''VideoGame/DevilMayCry4'' and ''VideoGame/DevilMayCry5'' wears a blue BadassLongcoat. This is in notable contrast to Dante, the original hero of the franchise who wears a red coat. Nero's outfit has a bit of red in it symbolizing how he combines the best aspects of Dante and Vergil, [[spoiler:who is his father]].
* ''Franchise/DragonAge'': Despite their name, the Grey Wardens are depicted wearing blue-colored uniforms from the [[VideoGame/DragonAgeII second game]] onward, which is ironic because they wore grey/brown outfits in the original game. In either case, the Wardens serve as one of the greatest defenders of Thedas against the [[TheCorruption Blight masses]]. However, the lengths they are willing to go are can easily force them to go into KnightTemplar territory.
* ''VideoGame/{{Elsword}}'': Chung, one of the playable characters, is color coded with blue, and unlike the main protagonist Elsword, Chung is more heroic, noble, and innocent (being a prince helps).
* In ''VideoGame/FairyGodmotherTycoon'', the different factions are ColourCodedForYourConvenience to show how well their business is operating in different parts of the kingdom. As the hero of the game, your color is blue.
* The ''Franchise/FireEmblem'' series:
** With a couple of exceptions, the main protagonist is always depicted with distinguishable blue hair, with blue clothes to boot. In addition, the player's units are color-coded blue to contrast with the enemy's red. This trope applies since most of the player kingdoms or factions are usually on the good side.
** Marth, the protagonist of the [[VideoGame/FireEmblemShadowDragonAndTheBladeOfLight first game]], becomes the best example of the franchise, as he has blue hair and outfit, and is also unambiguously one of the most heroic of the ''Fire Emblem'' protagonists, if not ''the'' most. His design becomes standard for most of the protagonists of the following games.[[note]]Design wise, [[VideoGame/FireEmblemTheBindingBlade Roy]] is basically "Marth with red hair", with [[VideoGame/FireEmblemTheBlazingBlade Eliwood]], being his father, shares the StrongFamilyResemblance. There's also [[VideoGame/FireEmblemTheSacredStones Ephraim]], which is "Marth but with greener hair tone". [[VideoGame/FireEmblemGenealogyOfTheHolyWar Seliph]] can also be considered "Marth with longer hair", with his father Sigurd being a [[StrongFamilyResemblance more mature version]] of him. And that's not to mention better examples below.[[/note]]
** Being a descendant of Marth, Chrom from ''VideoGame/FireEmblemAwakening'' also has blue hair, and his outfit is also predominantly blue with white accents. While a more complicated character than his ancestor, he is still a heroic man. [[spoiler:The same goes for his daughter, Lucina, who even adopts the name of "Marth" when disguised, as well as any other children he sires, who all inherit his blue hair.]]
** ''VideoGame/FireEmblemThreeHouses'':
*** The protagonist Byleth has blue hair and eyes, and, while [[TheStoic very quiet and sullen-seeming]], is a BadassTeacher who looks out after their students and the soldiers they lead. [[spoiler:Their hair and eyes change to pale green about halfway through the game.]]
*** Dimitri hails from the Holy Kingdom of Faerghus, and both he and his kingdom are predominantly associated with the color blue. On the Azure Moon route, he is the hero trying to save the continent from a power-hungry warlord.
** Alear, the protagonist of ''VideoGame/FireEmblemEngage'' is an interesting case, in that while they have a white and blue outfit, like Chrom, their hair is a strange mix of blue and red (and even has heterochromatic eyes- one red, one blue). [[spoiler:There's a good reason for this- Alear used to have fully red hair and eyes due to their heritage as a Fell Dragon, but it turned part-blue due to being infused with the essence of the Divine Dragon Lumera. While using their powers as the Fire Emblem, Alear's hair and eyes turn fully blue, having fully embraced their Divine Dragon heritage from their adoptive mother.]]
* ''VideoGame/GingerBeyondTheCrystal'': [[PlayerCharacter Ginger]] is a blue-skinned individual who's on a quest to restore the land, and the world crystal.
* ''VideoGame/{{Gradius}}'': While the [[CoolStarShip Vic Viper]] is predominantly white, the [[AnimalMotif snake-themed]] fighter has blue accents on its wings, dorsal tail, and prongs. In some games, it's usually [[OrangeBlueContrast orange]] [[AttackDrone Options]] will also be colored blue. Either way, the Vic Viper is a heroic fighter whose pilots ([[AcePilot James Burton]] being the first to pilot the Vic Viper) battle the [[TheVirus Bacterions]] for countless generations, ensuring peace for planet Gradius and the universe after each victory.
* ''VideoGame/GuiltyGear'':
** Ky Kiske is primarily associated with blue and he's the more straight-up heroic (to a [[KnightTemplar fault]]) out of the two main protagonists.
** Ky's son Sin plays this straighter than his dad being more innocent.
** There's also Axl Low who's a time-traveling pacifist and Vemon a noble and compassionate assassin who wears blue with his white.
* ''VideoGame/{{Hamsterdam}}'': [[PlayerCharacter Pimm]]'s default outfit at the start of the game is a blue jacket. Pimm is a BadassAdorable hamster out to save his town from the Vermin Gang.
* ''VideoGame/HoshiWoMiruHito'': Starting protagonist Minami's outfit and hair is blue, and he begins as the sole remaining hope of liberating the world from the supercomputer's tyranny.
* In the world of ''VideoGame/LeagueOfLegends'', the two most important nations are Noxus and Demacia. Noxians, who wear red, value strength in any form and see brutal ambition as a positive thing. Demacians value justice, benevolence, and selflessness. They wear blue.
* Janos Aldron in ''VideoGame/LegacyOfKain'' is a blue-skinned Ancient Vampire, and is arguably the [[TokenGoodTeammate most unambiguously heroic vampire]] among the cast who are either {{Magnificent Bastard}}s or {{Knight Templar}}s.
* Link, the hero of Hyrule from ''Franchise/TheLegendOfZelda'' series, who in each game saves the kingdom from the evil Ganon:
** Although he's associated mostly with green, he usually gets blue as a prominent secondary color by the [[CoolSword Master Sword]], whose hilt is purplish-blue, and all his forms of SwordLines, SwordBeam and such, light blue. Also, the Hylian Shield has a lot of blue in it. In ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'', he has very blue eyes and, in his animal form, is often identified as "the blue-eyed wolf."
** Link begins ''VideoGame/TheLegendOfZeldaTheWindWaker'' with a blue tunic before getting the Hero's Clothes, and the NewGamePlus allows him to wear his starting outfit for the whole adventure.
** Played completely straight in ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of the Wild]]''. Albeit the player can put different clothes, blue is by far the most common color in Link's wardrobe, and he is shown with the Champion's Tunic, a blue shirt very similar to the one in ''The Wind Waker'', in both promotional material and flashbacks. Zelda and the other Champions also wear their own NonUniformUniform variants with the same blue motif.
** Princess Zelda herself, who is a BigGood for Hyrule in every game where she appears, is frequently associated with the color blue. The official artwork for some games (''[[VideoGame/TheLegendOfZeldaALinkToThePast A Link to the Past]], Breath of the Wild'') depicts her in blue outfits. She also often has blue eyes and/or blue jewels in her crown, such as in ''Twilight Princess''. Moreover, as the wielder of the Triforce of Wisdom, she serves the goddess Nayru, who is associated with the color blue as well.
* In ''VideoGame/LonesomeVillage'', the hero, Wes, is a coyote who wears a blue outfit that looks rather like Link's tunic in ''VideoGame/TheLegendOfZeldaBreathOfTheWild''.
* ''Franchise/MegaMan'': While the titular character has gone through various reimaginings and incarnations ([[VideoGame/MegaManClassic including]] [[VideoGame/MegaManX being a robot]], [[VideoGame/MegaManStarForce a human powered by an electric alien]], [[VideoGame/MegaManBattleNetwork a computer program]], etc.), one thing that remained consistent is that his default armor color is bright blue.
* ''Franchise/MortalKombat'': While the main hero Liu Kang prefers [[RedIsHeroic red]], the color blue is more common among the heroes than any other color. [[CelebritySuperhero Johnny Cage]], [[WarriorPrincess Kitana]], [[TheAtoner Sub-Zero II]], [[BigGood Raiden]], [[BadassNative Nightwolf]] and [[SuperCop Stryker]] have all worn blue. The two notable exceptions to this are the original Sub-Zero who still had some good in him before he was killed and revived as a revenant and Frost, Sub-Zero II's DeceptiveDisciple.
%%Administrivia/ZeroContextExample* ''VideoGame/NinjaBattleHeroes'': HeroProtagonist Saizo Kirigakure has a blue outfit.
* ''VideoGame/NinjaGaiden'': [[HeroProtagonist Ryu Hayabusa]] wears a dark blue ninja uniform in the original NES games. The blue outfit can be [[AndYourRewardIsClothes unlocked]] in ''Sigma'' by beating the game on normal and in ''Sigma 2'' by beating 10 Team Missions.
* ''VideoGame/OceanhornMonsterOfUnchartedSeas'': The PlayerCharacter is a young man on a quest to find his father, who went out to defeat the SeaMonster Oceanhorn. He also wears a blue shirt.
* ''VideoGame/{{Pankapu}}'': [[TheProtagonist Pankapu]]'s Wizard robe when he's equipping The Faith Aegis is blue, he has blue eyes, and he's the warrior created by Iketomi to stop the Hya'Nagi from invading.
* In ''VideoGame/PlanetSide 1'', the New Conglomerate freedom fighters deck out all their equipment in blue trimmed with gold highlights. In comparison, the oppressive Terran Republic has [[RedAndBlackAndEvilAllOver black and red]] equipment, and the fanatical {{Precursors}}-worshiping Vanu Sovereignty uses purple and cyan. Averted in the sequel which trends towards GreyAndGrayMorality, where the NC are backed by {{Mega Corp}}s and PrivateMilitaryContractors only in it for the profit margins, and the Terran Republic is a democracy forced into drastic measures.
* Sparkster, the main protagonist of the ''VideoGame/RocketKnightAdventures'' series, has a light blue armor which is put in contrast with his EvilCounterpart, Axel Gear, who wears [[DarkIsEvil a suit of dark purple armor]] (Red in the 2010 game, ''Rocket Knight''), as well as the green armor of Emperor Devligus Devotindos' Pig Soldiers in the original game, and the purple armor of King Gedol's Lizard soldiers in the Genesis sequel, ''Sparkster: Rocket Knight Adventures 2''.
* The titular character from VideoGame/ShovelKnight dons a set of shining blue armor. It also puts his heroism in contrast to the more morally ambiguous characters such as his [[TheRival rival]] AntiVillain BlackKnight, as well as the straight up villainous BigBad [[SecondaryColorNemesis Enchantress]].
** In ''Specter Of Torment'', prior to his [[FallenHero fall into darkness]], [[AntiVillain Specter Knight]] dons a blue cape as the heroic Donovan. This symbolizes the [[EvilCostumeSwitch contrast]] with his current self, who wears red and [[TheDragon loyal]] to the [[BigBad Enchantress]], albeit [[TakeMeInstead with his own reasons]].
* ''VideoGame/SkeletonBoomerang'': [[PlayerCharacter Hunter]] wears a blue jacket, and is on a quest to save the world from [[BigBad Mr. Saturday]] and his [[DemBones skeleton army]], as well as lift the curse Mr. Saturday placed on his family bloodline.
* In ''VideoGame/SkiesOfArcadia'', there are two factions of pirates: Blue Rogues and Black Pirates. Despite both of them being in BlackAndGrayMorality, the members of the former act more like heroic [[JustLikeRobinHood Robin Hood]] and only plunder armed ships, most of which belong to evil Valua Empire anyway. They'll also spare lives if possible. In contrast, the Black Pirates attack their victims indiscriminately and are straight-up cutthroat evils. The [[TheHero heroic]] protagonist, Vyse, also has a blue color scheme. In fact, complementary material states that his birthdate links him to the Blue Moon.[[note]]The world of Skies of Arcadia has six moons of different colors, and follows a fictional zodiacal system based on them[[/note]]
* ''Franchise/SonicTheHedgehog''. His blueness represents freedom and clear blue skies, as well as his generally easygoing nature. This is put in contrast with [[BigBad Eggman]]'s [[RedAndBlackAndEvilAllOver redness]] as well as [[TheBigGuy Knuckles']] [[HairTriggerTemper intense red]] and [[TheRival Shadow's]] [[RedAndBlackAndEvilAllOver red accents]].

[[folder:Web Animation]]
* ''WebAnimation/HappyTreeFriends'': Splendid is a blue flying squirrel who happens to be a superhero. Though he is [[DestructiveSaviour absolutely]] [[FailureHero horrible]] as one.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/{{Homestuck}}'': TheLeader of each CastHerd is strongly associated with blue, though this gets played with as the story progresses:
** John has blue eyes, types in blue text, and is overall associated with blue, due to his [[BlowYouAway wind powers]] and association with [[HeavenlyBlue the sky]]. After Act 5 he always wears his sky blue [[spoiler: god-tier Heir of Breath]] pajamas. He's the protagonist of the story, the leader of the Beta Kids, takes a major role in saving everyone after the Game Over timeline, and ultimately [[spoiler: deals the final blow against the story's main villain]]. He starts off as a naïve goofball and one of the least cynical characters, and as the story progresses he becomes more emotionally numb and muted.
** Vriska is also associated with blue, having blue text and blue blood. While personality-wise she's more of an AntiHero (and how sympathetic she is is hotly debated), she thinks of herself as the real hero of the story and [[SpotlightStealingSquad usurps various other characters' role of actively opposing the villain]]. She singlehandedly goes up against the DiscOneFinalBoss at the end of Act 5, and at the end of the story leads [[spoiler: a massive ghost army against the BigBad]].
** Subverted with Jane. She has light blue eyes and text [[spoiler: and once she gets god-tier powers her Maid of Life magic is also blue]] and is introduced as fitting John's role, with the assumption that she will be the HeroProtagonist of Act 6. While Dirk insists she's the leader of their team, due to the nature of their void session she doesn't end up doing much leading. Although the hero aspect is subverted, she fits some of the personality aspects, being analytic, old-fashioned, and proper.
* ''Webcomic/TheOrderOfTheStick'':
** Roy, [[HeroesPreferSwords sword-bearing]] [[TheLeader leader]] of the Order of the Stick, a RagtagBunchOfMisfits who quest to defeat the evil sorcerer Xykon and, eventually, [[spoiler: prevent the destruction of the world]], wears primarily blue armor. His fellow team member Elan, TheHeart of the party, the team's moral compass, and the most pure-hearted, unambiguously Good member, also has a blue motif, wearing a blue cape and then a blue vest and eventually an all-blue outfit. None of the other team members, all of whom are more morally ambiguous or less inclined to lead, ever wear blue.
** Azure City is heavily blue-themed, as most inhabitants wear blue and many have blue hair. The few exceptions are Azurites who are outright villainous (like Tsukiko and Kubota) or morally grey, like Therkla. Their entire society is built around The Sapphire Guard, an order of [[ThePaladin paladins]] whose secret mission is [[spoiler: to protect the Gates, a CosmicKeystone whose destruction would lead to the end of the world]]. Blue is the uniform color of the Sapphire Guard, who become important allies of the Order. While not everyone in Azure City is necessarily heroic, it's an entire society in which the ideal of TheParagon is deeply ingrained.

[[folder:Western Animation]]
* ''WesternAnimation/AdventuresOfTheGalaxyRangers'': The Series 5 team wear white and blue uniforms for the most part. Shane, the closest the team gets to an anti-hero, sometimes has an all-black outfit, however.
* [[Characters/AdventureTimeFinn Finn]], the main character of ''WesternAnimation/AdventureTime'', wears a light blue shirt and dark blue pants. He spends much of the story serving as Princess Bubblegum's main bodyguard/knight and fighting the evil Lich. Although he definitely has a sense of righteousness, his personality is [[BloodKnight pretty much the opposite of "calm"]].
* Anne Boonchuy, the hero of ''WesternAnimation/{{Amphibia}}'', has powers that glow blue when she uses them.
* ''Franchise/AvatarTheLastAirbender'' franchise:
** Blue is the color of the [[WaterIsBlue Water Tribe]], the nation with the greatest number of prominent heroic characters. In fact, the concept of bad Water Tribe members only really comes to fruition (excluding Hama) with the Northern Water Tribe in the SequelSeries.
** This trope is used to full effect in the GrandFinale of ''WesternAnimation/AvatarTheLastAirbender'', in [[spoiler:the scene where Aang takes Fire Lord Ozai's bending away, both enter in a ThroatLight state, being [[Characters/AvatarTheLastAirbenderAvatarAang Aang's]] light blue and Ozai's red]].
** In the ''WesternAnimation/TheLegendOfKorra'', where the Avatar enters the Avatar State, their eyes glow light blue. It was explained in ''Book 2: Spirits'' that [[spoiler:this is the manifestation of Raava, the Spirit of Light, who is this color in opposition of Vaatu, the Spirit of Darkness, who is dark red]].
** Additionally, [[Characters/TheLegendOfKorraAvatarKorra the titular heroine]] not only naturally wears the color because it's her homeland's, but even wears a darker blue than she previously wore in the latter half of Book 4 once she's properly back in action.
* The ''WesternAnimation/{{Dinosaucers}} ''all wear shades of blue and green in their armor, to contrast with the Tyrannos and their villainous red and orange.
* ''WesternAnimation/{{Dragamonz}}'': Dax is a Stormclaw Dragamon with blue scales, and he is tasked with recruiting the leaders of the other factions so that he can use the Crystal of the Five Corners to restore Dragamar to its original state.
* ''WesternAnimation/FinalSpace'': Some of the Infinity Guard's uniforms are blue, notably those worn by some of their heroic officers such as Quinn and John Goodspeed.
* ''WesternAnimation/{{Freakazoid}}'': The titular protagonist has blue skin and is a heroic, if extremely weird, person.
* ''WesternAnimation/JackieChanAdventures'': The eponymous hero is an AdventurerArchaeologist who often wears a blue shirt and fights crime lords, demons, evil sorcerers, and all manner of villains who threaten the innocent. While Jackie would rather live a peaceful, quiet life as a researcher and antique shop owner, he is more than capable of stepping up and saving the day when needed.
* ''WesternAnimation/JusticeLeague Unlimited'': Superman. While he does have the red cape to signify "action", his costume is predominantly blue. The intro background for Superman's card is blue. He's usually the voice of reason, especially when paired with Batman (dark red background), or even Wonder Woman, who occasionally wears a blue cape over her predominantly red costume.
* ''WesternAnimation/MegasXLR'': The titular robot is piloted by the main protagonist [[DestructiveSaviour Coop]]. The robot is the last line of defense against the Glorft, alien race that seeks to conquer humanity and were actually the ones who created Megas. We don't see what Megas looked like before it was taken by Kiva but it was likely [[GreenAndMean the same color as other Glorft mechs]].
* Tooey from ''WesternAnimation/MollyOfDenali'' wears a completely blue outfit, and is one of the show's heroes. His blue outfit also contrasts with Molly's [[RedIsHeroic red outfit]].
* ''WesternAnimation/MyLifeAsATeenageRobot'': Jenny is a teenage blue-and-white robot who divides her time between saving the world, going to school, and hanging out with her friends.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' features [[Characters/FriendshipIsMagicRainbowDash Rainbow Dash]] (who has a cyan blue coat) as one of the six main characters, and while she's not the leader of their group of friends, she ''does'' lead Ponyville's weather pegasi before she becomes part of the Wonderbolts.
* Perry from ''WesternAnimation/{{Phineas and Ferb}}'' is a blue-furred platypus who is a secret agent working for the O.W.C.A. trying to stop Dr. Doofenshmirtz from taking over Danville.
%%Administrivia/PartialContextExample* ''WesternAnimation/ReBoot'': Bob's Guardian uniform is predominantly blue ([[AmazingTechnicolorPopulation hell, his skin is blue too]]). Enzo receives a similar uniform during the season 2 finale.
* ''WesternAnimation/{{Robotboy}}'': The eponymous character is a heroic blue RobotKid who fights [[MadScientist the evil Dr. Kimakazi]].
* ''Franchise/TheSmurfs'': The titular main characters of the franchise are little blue creatures who are very cheerful and on the heroic side.
* ''WesternAnimation/StarWarsTheCloneWars'' plays with this trope ''while'' playing it straight:
** Straight: As in the movies, Anakin, Obi-Wan, and a lot of the other Jedi wield blue lightsabers. Aayla Secura also has blue ''skin''. And in the UnCanceled [[WesternAnimation/StarWarsTheCloneWarsSeasonSeven season 7]], Ahsoka's lightsabers, previously green and yellow, are blue when returned to her before the Siege of Mandalore.
** Now, here's where the PlayingWithATrope comes in:
*** As time goes on, the Separatists, whose ''military'' is certainly evil, gain an increasing number of blue-and-white-painted vehicles, whereas Republic vehicles tend to have a white-and-red colour scheme.
*** The 501[-[[superscript:st]]-] Legion, the most commonly appearing clone unit in the series, has blue markings as their unit colour. Now, while almost every individual member of the unit who gets characterization (Rex, Fives, Jesse, Kix, etc.) is heroic (except for the LawfulStupid Dogma), ''Franchise/StarWars'' fans will be aware that, after the execution of [[ThePurge Order 66]], the 501[-[[superscript:st]]-] is led by Anakin/Vader to storm the Jedi Temple in ''Film/RevengeOfTheSith'', after the clones' ManchurianAgent control chips have been activated. And increasingly, as the series goes on, the red-clad Coruscant Guard is shown as sinister, being the clones who, by the nature of being stationed on the Republic's capital planet, are the most often unwittingly directly helping to further Palpatine's evil scheme.
* The main hero of ''WesternAnimation/StaticShock'' wears a blue longcoat and boots as part of his superhero costume.
* In ''WesternAnimation/{{Supernoobs}}'' Tyler's battleball is colored blue, and his hair becomes blue when he puts on his battle armor, which he uses when leading the team in fighting against a virus threatening the planet.
* Whyatt, the leader of the superhero group "Super Readers" from ''WesternAnimation/SuperWhy'' wears a dark blue polo shirt and has [[InnocentBlueEyes blue eyes]]. While Super Why's outfit is primarily green, it does have blue accents.
* Leonardo, the leader of the ''Franchise/TeenageMutantNinjaTurtles''. His blue bandana (introduced in [[WesternAnimation/TeenageMutantNinjaTurtles1987 the 1987 series]]) is indicative of his calmness, spirituality, and reliability.
* While Autobot leadership and the Autobrand are defined by red in ''Franchise/{{Transformers}}'', many continuities portray Decepticons with [[RedEyesTakeWarning red eyes]] and give the Autobots [[InnocentBlueEyes calm, blue eyes]].
