These blue eyes indicate a character who either is demonic or possesses the "evil eye", magic, or witchcraft. In Mediterranean countries, this comes from the Demon's Eye amulet, which is always blue. Blue (or gray) is also the eye colour of choice for many wizards who are eerie or sophisticated instead of mysterious.

Commonly, these eyes weren't ''originally'' blue, but ''became'' that way through prolonged use of magic.

GlowingEyelightsOfUndeath often take this colour, when they aren't {{red|EyesTakeWarning}}.



[[folder:Anime & Manga]]
* ''Anime/DevilHunterYohko'' has all humans with brown eyes, whilst the demon characters have blue.
* Midou Ban of ''Manga/GetBackers'' has almost preternaturally blue eyes, as well as being an actual case of association with witches, as noted above. He also has the ability to give the MagicalEye.
* In ''Manga/KatekyoHitmanReborn'', according to Gamma, many of the Sky Arcobaleno characters' eyes tend to look as if they expect an event would happen. [[spoiler:It's true, since the Sky Arcobaleno have the ability to see the future.]]
* In ''Manga/BlueExorcist'', Rin Okumura seems to fit the demonic type (being the son of {{Satan}} and all).
* In ''Manga/TsubasaReservoirChronicle'', Fay's magic is explicitly tied with the blue ''color'' in his eyes, which is weird but still awesome.
* ''Manga/MahouSenseiNegima'':
** Fate is what Evangeline called a 'doll', being a magical creation of the Lifemaker, extremely proper and TheStoic early in the story, [[SeriousBusiness but prefers to drink coffee instead of tea]].
** Evangeline is a blue-eyed vampire who is Really700YearsOld.
* Diva from ''Anime/BloodPlus'' has blue eyes. When they start to glow even bluer, it's not a good sign.
* ''[[Literature/TeitoMonogatari Doomed Megalopolis]]'' had a monk character called Kamo, whose eyes are usually squinted. But when opened, are revealed to be blue with YELLOW whites! Kamo only appeared in chapters 1 and 2.
* ''Anime/YuGiOh'' has season 4's Atlantean villain [[BigBad Dartz]] depicted with one yellow eye and one blue eye. The Orichalcos had infected him and changed one of his eyes from yellow to blue. In [[RealLife real life]] yellow is the unnatural eye colour whilst blue is very common but then again this is anime. The Orichalcos stones are blue and much of Dartz's attire consists of blue as well to hammer home this trope.
** Additionally, there is Kisara from season 5. She is exiled from most civilization because she has pale skin and blue eyes (very unusual for Egypt at that time), and is believed to be a witch. They aren't exactly wrong; [[spoiler: her ka is the Blue-Eyes White Dragon, the most powerful one not possessed by one of the six priests.]]
* Norway from ''WebComic/AxisPowersHetalia'', mixed with CreepyBlueEyes, though sometimes they're coloured purple. He can see and speak to supernatural creatures and have been hinted to be able to use BlackMagic.
* Taoist monster hunter Hyo from ''Manga/UshioAndTora'' has a magical blue eye which has mystic powers, allowing him to see monsters for what they are, even when hidden. When he first appears, the demons he's fighting recognize him from that blue eye.

[[folder:Comic Books]]

* Comicbook/DoctorStrange's eyes are blue in most depictions, though according to his official description they are grey. Sometimes they have a creepy greenish tinge.
* In ''ComicBook/YoungAvengers'', Wiccan is one of the candidates for Sorcerer Supreme, and he is usually drawn with brown or hazel eyes, despite his official bio saying that he has blue.
* {{Superman}} is said to have "unearthly" blue eyes - one very big part of why he wears extremely thick glasses when in his Metropolis-Clark disguise (they obscure and diffuse the color).

[[folder: Fanworks]]
* "FanFic/ReverseFallsAU" is a popular FandomSpecificPlot for the ''WesternAnimation/GravityFalls'' fandom. It's a role reversal [=AU=] where the Pine twins are in Gideon's role while Gideon and Pacifica are in theirs. Mabel and Dipper are always depicted with CreepyBlueEyes that usually glow, and they have psychic powers. In contrast, main continuity Dipper and Mabel are usually depicted with brown eyes (though InnocentBlueEyes isn't too uncommon either).

[[folder:Live Action Film]]
* ''Film/{{The Avengers|2012}}'' shows victims of Loki's MindControl staff gaining these, which disappear when his hold over them is broken. Creator/JossWhedon specially mentions on the commentary that these were added in post-production so the audience would be absolutely sure that someone was or was not being controlled.

* Felix's blue eye in ''Literature/DoctrineOfLabyrinths'' is treated this way by the superstitious denizens of the Lower City.
* The influence of the spice melange in ''Franchise/{{Dune}}'' turns the ''whites'' of people's eyes an unnaturally bright blue. According to the in-universe science, the whites turning blue (known as "eyes of Ibad") is a normal biological reaction of humans exposed to spice. However, spice also as some psychoactive effects and gives psionic abilities to at least some humans, which links the two together in people's minds. While most people have to consume large doses of spice for their eyes to change color, it's so omnipresent on Arrakis, the planet which produces it that every native has this effect to one degree or another.
* Blue eyes are considered [[CreepyBlueEyes automatically creepy]], for this reason, in ''TabletopGame/EmpireOfThePetalThrone''.

* In Creator/TamoraPierce's ''Literature/ProvostsDog'' books, Bekah Cooper has "ghost eyes" that go from pale blue to ice colored when she's upset (may have something to do with her unofficial {{psychopomp}} status). She uses these to her advantage when she has a need to frighten people, usually criminals.
* In the ''Literature/{{Safehold}}'' series, an affectation by the late Nimue Alban means that her most-commonly used [[RidiculouslyHumanRobot avatar]]/persona has become known for [[GenderBender his]] "unearthly ''seijin''-blue eyes".

** Someone who has been raised from the dead by the Others has uncanny shining blue eyes with no life in them, usually described as looking like the cold light of distant stars.

* In Creator/OrsonScottCard's ''Literature/TheWorthingSaga'', IcyBlueEyes are part of a genetic package that includes [[MindReading telepathy]] and (after copious amounts of inbreeding) various other PsychicPowers.
* In Literature/TheStormlightArchive, Kaladin ends up with these at the end of Literature/WordsOfRadiance, after speaking the Third Ideal of the Windrunners though it only lasts a few hours after each time he uses his Shardblade.
* ''Literature/JourneyToChaos'': [[Literature/AMagesPower In the first book of the series]], Tasio the Trickster expresses interest in changing Eric's eyes from the Innocent variety to one of these.

* In ''Literature/KushielsLegacy'', [[spoiler:Hyacinthe]] the Master of the Straits' eyes turn a vivid blue that deepens and darkens towards the pupils. The change is a sign of his power over the oceans.
* In the ebook ''Literature/LockhartandTeague:TheEmptyChest'' Avalyn Teague belongs to a cult of powerful magic users and is described as having very blue eyes. However, his eye color does not seem to be indicative of his status as a magic user as others of his kind don't have them.
* A number of the WizardsAndWitches in ''Literature/HarryPotter'' have blue eyes, but Albus Dumbledore's are described as especially piercing, which goes with his WizardClassic aesthetic.

[[folder:Live-Action TV]]
* Illyria from ''Series/{{Angel}}'' looks like Fred with her whole body turned blue: just as Fred has brown hair, light brown skin, and brown eyes, so Illyria has blue hair, blue skinů and an unnatural shade of blue for her eyes. This use of blue eyes has the effect of making her look [[EldritchAbomination as eerie as possible]].
* The {{Dracula}} of the ''[[Series/BuffyTheVampireSlayer Buffyverse]]'' has several supernatural abilities which set him apart from other vampires, such as shapeshifting and hypnosis. Several characters in the episode "Buffy vs. Dracula" comment on his "dark, penetrating eyes", which are an unnatural shade of dark blue.

[[folder:Tabletop Games]]
* In ''TabletopGame/WarhammerFantasy'', the [[HornyVikings Norse]] consider blue eyes to be a sign of favour by the [[EldritchAbomination Chaos God Tzeentch]]. Since Tzeentch is not only the patron god of sorcery, but a ManipulativeBastard extraordinaire who's even fonder of inflicting [[BodyHorror mutations]] on his favourites than his brothers are, this may or may not be a good thing.
