Red Eyes, Take Warning

Go To
Tak: I'm Tak of the Pupununu People. You are the good guys aren't you?
SpongeBob SquarePants: Sure! It's the beady red eyes that are a dead giveaway for the evil fellows.

An easy way to tell a villainous (or sinister) character apart from the protagonists, other than giving them a Red Right Hand, is making their eyes red. If they don't start out evil, there's a chance they become so over time or perform full-blown Face–Heel Turn. It's not the same thing as the "red eye" phenomenon in photos, but if cameras could detect evil, or danger these would be the first people they'd catch.

Even those who aren't truly evil or dangerous are often thought to be so by characters In-Universe.

In the progressive algorithm of "Uh-Oh" Eyes we have:

Supernatural Gold Eyes < Red Eyes, Take Warning < Hellish Pupils < Glowing Eyes of Doom

Those with glowing red eyes are almost without exception thoroughly evil or, at least, very dangerous. The "almost" section goes to those whose red eyes serve as a marker for their Elemental Powers, typically fire. Albino characters with red eyes may suffer from this association with evil; see Albinos Are Freaks.


A subtrope of Technicolor Eyes. Compare Glamour Failure, Red Is Violent and Creepy Blue Eyes. Contrast Red Is Heroic.

Not to be confused with the film Red Eye or the liquor. Sometimes a part of Burning with Anger, and thus a harbinger of wrath.

It should be noted that this trope is NOT just for characters who have eyes of this color, but when the color actually indicates the character is evil or dangerous, or presumed to be because of their eye color. Please do not add characters who just happen to have eyes of this color without the proper reason behind it.

    Comic Strips 
  • These aren't a constant for any character in Candorville, but most vampires can activate and deactivate them at will. The only exception so far is Saxon, who gets Milky White Eyes either because of his Dhampyr status or because he's a Friendly Neighborhood Vampire.
  • Garfield:
    • The art style usually doesn't allow for eye colors at all, but the infamous "abandoned house" sequence (beginning here) has a close-up of one of Garfield's eyes in the final strip, red like blood, with the pupil contorted into a spiral as he refuses to accept what he sees.
    • In another very early strip around Halloween, Garfield explains that around that time cats become bewitched. His eyes began to turn red among other things... that is until he saw himself in the mirror, screamed turned white and passed out.
  • Al Capp's Li'l Abner strip had the Nogoodniks, which were the evil version of the Shmoos. They were a sickly shade of green and had "li'l red eyes". They devoured "good" Shmoos, were the sworn enemies of "hoomanity," and wreaked havoc on Dogpatch.

    "Ohshit," whispered Touji. "She's mad."

  • Shadamy Comic: When it's revealed that Infinite is pretending to be Sonic, "Sonic" gains glowing red eyes.
  • Sonic.exe: The evil version of Sonic first glimpsed on the title screen has pitch-black irises and "two glowing red dots" for pupils.

Steven Universe

  • We Can Be Heroes: Val Kazkani is an albino alien mobster who regularly terrorizes and bullies the citizens of Krapton, and a boorish thug towards everyone outside his immediate family. The narrative draws a lot of attention to his blood-red eyes, and his youngest sister Su mentions to Lapis that his parents were hoping to exploit the genetic quirks afforded to him as an albino to make him scarier to the people he extorts.

  • Dungeon Keeper Ami features this prominently. Keepers all have red, glowing eyes due to the dark magic of their Dungeon Hearts, and they glow brighter when feeling strong emotions, such as anger.

  • My Immortal: Averted and played straight with different characters. Vampires Ebony and Draco either have red eyes or wear red contacts, and are (supposedly) good guys. Played straight in that Voldemort (also known as Vlodemort, Vloxemort and other variations), the Big Bad of the story, is frequently described as having red eyes.
  • The Night Unfurls: Kyril's eyes are as red as spilled blood, fitting for one who has mastered the art of hunting. Far from the only reason why he is a Terror Hero that instils dread into the hearts of many.
  • Rescuing Dara averts this trope, with the hero Chivai and both the heroic and villainous Lucarios all having red eyes.
  • Scoob and Shag: Unlike other characters' white effects, Number One's eyes and Magical Eye Streamers glow red when he uses his powers. The glow from his eyes is strong enough to actually light up parts of the scene in episode #74. The fact that his eyes are a consistent color serves as both a signifier of how much danger he poses to the others and as a hint at how much his Ballyhoo energy has corrupted him.

  • In Care Bears Movie II: A New Generation, Dark Heart has red eyes (and hair and clothes) in his human form. When his eyes change color, it clues everyone in that his Heel–Face Turn turned him into a normal kid.

  • The PNK sorority girls in Monsters University. They're usually bubbly valley girl types, but when they get down to scaring, yikes.
  • Spoofed in Monsters vs. Aliens. After being imprisoned by the military merely for being a 49-foot, 11-inch monster woman, Susan starts banging on the walls of her prison. The other monsters warn her not to do that, whereupon a huge door opens to reveal a dark interior with two glowing red eyes within...which merely turn out to be the lights on General Monger's Jet Pack.

  • Mogwai in the Gremlins series when they've eaten after midnight and become evil.
  • Voldemort in Harry Potter and the Philosopher's Stone, staying true to the original story. Later films were much less accurate, giving him Creepy Blue Eyes. According to the creative director this was to give an Uncanny Valley effect as Voldemort is more appalling if there's still a trace of humanity in his face. This idea works, especially in Goblet of Fire.
  • Horrific: In Crypt of the Undead, the undead executioners have red eyes, as does anyone possessed by the ghosts of the witches.

    • Spider-Man: Homecoming; Spidey's suit has a Instant Kill Mode which turns the normally wide white eyes of Spider-Man into small red glowing pupils. Peter, who follows the Thou Shalt Not Kill rule, takes issue with it. He then gets to use it in Avengers: Endgame to decimate Thanos's Outriders.

  • Star Wars: The "Sith eyes" seen on Darth Sidious, and later Darths Maul and Vader in the prequels (technically gold rimmed and flecked with red, but it still counts) Maul is shown to have them all the time, but he's not human and his eye color is never seen while he's doing anything but hunting the heroes and fighting. Vader is only seen with them when he's feeling particularly "eeevil." Sidious' eye color, on the other hand, switches between Sith gold and their original blue depending on whether he is being his evil self or masquerading as a benevolent politician. Ultimately, his eyes become gold-red permanently after his grueling duel with Mace Windu.
    • This trope is applied sometimes with Count Dooku, a.k.a. Darth Tyranus, who is seen with Sith eyes few times in animation and novels but not in the prequel movies.
    • The eyes of Cad Bane from The Clone Wars, the Nemoidians and Grand Admiral Thrawn may fit this trope better on a superficial level (being pure red), but this is only because that's the natural eye color of their respective races — not Sith sorcery.
    • In the theatrical version of A New Hope, Vader's eye lenses had a dull reddish tint to them due to the materials used. It probably wasn't intentional, due to the fact that later edits removed the reddishness in order to hide David Prowse's eyes. However the red lenses are brought back in Rogue One and they look great.
    • Played with in Solo when Qi'ra contacts the previous unseen leader of Crimson Dawn, revealed to be Darth Maul.

    • In Shadows for Silence in the Forests of Hell, the shades normally drift away from humans and are mostly harmless unless you manage to walk right into one despite them drifting away. But break the Simple Rules (don't move too fast at night, don't kindle fire, and never draw blood), and their eyes light up red as they enrage. If that happens, if there is a nearby safe place enclosed by silver, run there. Otherwise, your ass is toast.

They are variously described as lifeless, reptilian, unnerving, cold and dead.
  • In the original picture book of Mars Needs Moms, Milo's mom (and Milo himself) have bright orange-red eyes. It doesn't mean anything but it does make The Reveal of Mom's face a little unnerving.

  • The second Vorlon Ambassador in Babylon 5 has a red light in the "head" of his encounter suit, compared to the original Kosh's green. He's a much, much nastier person.
  • Battlestar Galactica: Cylons. The single red eye sweeping from side to side of their visor makes up a great deal of the Centurions' and Raiders' intimidation factor. Strangely, the only time we see a humanoid Cylon's eyes flash red, it's Sam Anders, one of the good ones.
  • Buck Rogers in the 25th Century episode "Space Vampire". The Vorvon's eyes glow red when it's using its Mind Control powers on a victim.

      • "Planet of the Ood": Random Ood at Ood Operations are getting "red-eye" and killing employees with their translator balls out of anger at the way they've been treated. The red eyes simply mean they're drawing on the telepathic field that connects them.
      • "The End of Time": Played with. This time, they're not getting violent, they're warning the Doctor that "The End of Time itself" is imminent. The elder Ood's eyes take on the red glow when showing the Doctor visions of the future. He's drawing on the Ood's psychic network to do it, which is in fact the true meaning of the red eyes. Before, it had been hijacked by the "devil", while later it let the occasional Ood overcome the slave programming and fight back against the real villains. We see the red-eye mode in its totally non-dangerous natural form in "The End of Time". Russell T. Davies, showrunner at the time, actually considered "glowing red eyes = evil" to be a played-out cliché, so it's no surprise he didn't play it straight..

In Episode 9 it's explicitly pointed out by TV pundits discussing the crisis, but this gets thrown out the window due to A.I.M.S.'

He shoots out the streetlight and leaves as the informant screams for help and the red-eyed critters start closing in on him.

  • Supernatural:
    • Crossroads Demons. Other demons have similarly evil shades of white, yellow, or black.

And the more and more he get's into a fight, the more his eyes start to glow and and take on Black Eyes of Crazy on top of it.

    • The camera has a tendency to zoom in on Emerald's vivid red eyes whenever she's tapping into her mind control powers, which bodes ill for the target of her power. She can make a target perceive anything she wants, and all the senses are fooled, not just sight. Emerald's abilities are the main reason why Cinder is so successful in destroying Beacon Academy and becoming the next Fall Maiden. She enables Amber to be ambushed by making Amber think there's a crying child in need of help, and ensures Amber has troubling seeing exactly where Cinder, Mercury and herself are during their fight even when looking straight at them.

  • The Bongcheon-Dong Ghost has red eyes, but by the time you see them, it's already very obvious...and too late.

  • Dan and Mab's Furry Adventures: Aaryanna, Aniz, Dark Pegasus, Kria, and Regina all have red eyes, and are all pretty evil to varying degrees (Villainy Discretion Shots notwithstanding).
  • The "tainted" or Ver'drowendar from Drowtales have red irises; they "have been seeded by a demonic entity". All drow naturally have red pupils, but this is the result of eyeshine and is an evolutionary adaptation to living underground, but results in tainted characters having red on red eyes.

    • The yellow salamander/lizard-thing. It may not have been evil, per se, but it was certainly dangerous. The lizard was a house fire that killed a small child and his family.
    • Zimmy plays an odd variation of the trope. Normally she seems to have Black Eyes of Evil, but when she is temporarily purified from the etheric miasma that pollutes her spirit by natural rain, it turns out that her eyes are bright crimson underneath. In this condition she is a lot more coherent and amiable than her usual self, but acts as a reminder that she's not exactly normal, either way.

  • Panim, the Misanthrope Supreme from Hello World.
  • Homestuck has Calliborn, having candy-red eyes and red swirls on his cheeks that turn into solid circles once he successfully kills Calliope. His eyes are no long red, but no less eerie, when he transforms into Lord English and his eyes turn into constantly cycling pool balls.
  • I'm the Grim Reaper: One of Scarlet's eyes tends to glow when she summons her scythe. Her irises are always bright red.
  • In Impure Blood, when annoyed. Note that her eyes can also glow blue for other magical purposes.
  • Kagerou: when (the aptly-named) Red takes over Kano's body, his eyes turn red. And Red is a psychopathic rapist and murderer.

  • Quite a few characters from L's Empire (most notably Dark Star). Pix averts this as, despite him always having red eyes due to being Dark Star's son, he's the nicest guy in existence.
  • In Looking for Group, most characters, regardless of whether they are evil or good, will display the "burst of anger" or bloodlust variant. Bloodrages will most prominently display it before dishing out punishment, but even Nice Guy Cale will display them in bouts of righteous anger.
  • Valentino, the Big Bad of Marilith, has red eyes. The effect is highlighted by the rest of the strip being mostly in black and white.
  • Otherworlders in Miamaska have red eyes and purple sclera. Citizens see this as a threat to their town and take action accordingly.
  • Noblesse: One of the major factions in the story is the nobles of Lukedonia, all of whom, including the protagonist Rai, have red eyes.
  • The Order of the Stick:
    • Sabine's eyes glow red in her true form. There is an early warning of her true nature in this strip, which is before she's revealed to be a fiend. Later, the glowing-red eyes are a hint for the reader that she's shapechanged.
    • Xykon has glowing red eyes too.
    • Also, Loki, god of Flames and Chaos.
    • Malack's eyes change to red from their usual pink when using his vampiric abilities.
  • Penny Arcade:
    • Tycho gets these whenever he gets particularly angry or is acting particularly evil, apparently because his body harbors a dark spectre from the world of dreams.
    • Penny Arcade sub-comic Automata. There's something in that time signature and it changes the eyes from the standard blue
  • In Phantomarine, Cheth's eyes turn red when he is experiencing extreme emotions.
  • Rescuing Dara averts this trope, with the hero Chivai and both the heroic and villainous Lucarios all having red eyes.

  • While this is not common due to the art style of Scandinavia and the World, it does occasionally show up, generally when either Åland or Finland are especially upset.
  • Slightly Damned: Subverted with Buwaro note  or Lakritz who are both among the kinder demons around, however red seems to be one of the most common demon eye colors and most of them play it straight. The most notable of these demons is Iratu who at first seems to be friendly but that's because he was drunk and when we see him sober we learn he is a cunning and powerful General of Hell's Army who leads an attack on a major city that kills hundreds if not thousands of innocent people.
  • Sluggy Freelance:
    • In one story, Bun-bun the evil mini-lop rabbit is stuck with the annoying animated shadow of the groundhog who's the Anthropomorphic Personification of Groundhog's Day. Unable to attack the insubstantial creature, he's forced to suffer all its antics. But finally it manages to do something that angers Bun-bun so much that he finally snaps. He gets so angry his eyes turn red, and subsequently he emits a red aura. Insofar as there is an explanation to this, it could be that by that time Bun-bun was already a mildly supernatural being due to being saddled with being the Easter Bunny as well as the official "groundhog".
      Shadow: What do you want to do?
      Kiki the ferret: I have a pretend karaoke machine made from a toilet-paper roll!
      Shadow: You like karaoke too?
      Kiki: I LOVE karaoke!
      Shadow: A one and a two and a
      Bun-bun: That's IT! Everybody dies!

  • Eli of Soul to Call has red, sometimes glowing eyes. While the population at large, especially The Order believes that he is dangerous, the fact is, that he is actually very meek, and shy. The red eyes glowing means that something else has just shown up, and that is what's actually dangerous.
  • Dr. Schtein of String Theory (2009) has prosthetic eyes that glow a sinister red, having lost his original eyes in a lab explosion. Thus far, they seem to be foreshadowing his eventual rise to supervillainy. They even glow in the dark, much to the horror of his prison roommate.

  • Underling: Demons. This is awkward for Lazarus when he gets them, and a tail, and horns.
  • Waterworks: Flush gains a set of red eyes just before he uses his deadly Spin Attack. "oh hey flush. you're sporting the evil red eye look rather nicely"

Still definitely a sign to take warning, though.
  • Odd variant: while Serpentor from G.I. Joe: A Real American Hero was always evil, his eyes briefly turned red when he held the battleax of Vlad the Impaler, one of the many historical tyrants whose DNA he shared.

  • Trina Riffin from Grojband whenever she's writing in her diary in Anger or Fear mode.
  • Skeletor, nemesis of He-Man from He-Man and the Masters of the Universe (2002). His eye (sockets) function as a literal warning, as little red lights start growing in them when he gets angry or excited in evil ways.

  • Dick Knubbler's robotic eyes turn red when he gets pissed off in Metalocalypse. Not so much "evil" as "Jerkass", but when one works for five Chaotic Neutral musicians that cause destruction wherever they go (by accident, sometimes, even!), it's hard to call oneself "good".
  • My Little Pony: Friendship Is Magic:
    • Discord's eyes are yellow with red pupils, and he used to be a villain.

While for the most part a neutral judge and even a Reasonable Authority Figure, his eyes glow bright red once and only once: when Peter so much as implies a human soul isn't the most valuable thing in existence. Peter immediately takes it back.
  • Samurai Jack has Mad Jack, Aku's embodiment of Jack's own dark side.

    • Averted with Entrapta. While she has dark red eyes and wears a creepy, red-eyed welding mask, she's True Neutral and most of the damage she causes is in pursuit of learning something new, as opposed to evil; indeed, she ends up as a Token Good Teammate to the Horde after her defection.
  • In Slugterra, the eyes of mecha-beasts turn red when they are ghouled; as seen in "Mecha Mutiny".
  • Dr. Julian Robotnik from Sonic the Hedgehog (SatAM) has a pair of red cybernetic optics that shine like hellish spotlights in the dark.

    • The 1973 episode "Menace of the White Dwarf". The evil Mad Scientist Raven (who acts more like a Comic Book supervillain than any other opponent the Superfriends faced during this season), has red eyes.
    • The evil Superman from the 1979 episode "Universe of Evil" has red eyes as well, and for bonus points, they're ringed in black, with freakin' huge demonic points. Evil!Batman and Evil!Robin also have red eyes in place of their good counterparts' plain white eyes.
  • Teen Titans (2003):
    • Trigon, very bad dude indeed.
    • Brother Blood, Big Bad of the third season, has eyes that glow red when he uses his Psychic Powers; in the fifth season, the mechanical eyes on the skull-"face" on the Brain's life-support pod also glow red when the Brain is interfacing with his computers or is just angry.

    • Raven isn't evil and her eyes are normally a deep purple, but when she goes One-Winged Angel her eyes glow solid red. And suddenly there's four of them. Makes sense since Trigon's her dad.

    • Transformers: Animated has all red-eyed (or in the case of Soundwave, red-sunglassed) Decepticons like the original cartoon, with the exception of the nominally-a-Decepticon Swindle, who has purple eyes. However, Sari Sumdac, a human child, also appears to have red eyes. They turned blue after she "upgraded" herself. Also, in Animated, Wreck-Gar's eyes turn red when he threatens to destroy Detroit as a reference to Transformers: The Movie and his G1 counterpart's toy commercial. An interesting example occurs in Wasp. Originally, he had blue eyes, but after his stay in prison (and subsequent madness and desire to turn Bumblebee into iron filings), they become purple. And what color do you get when you mix red and blue?
      • The Autobots' eyes also turned red when they were brainwashed by Soundwave into being evil.
    • Pops up a few times in Beast Wars', despite bots like Rattrap and Rhinox just normally having red optics, to warn you things are about to get real. When Megatron becomes a transmetal the first you see of him are his glowing red eyes against a silhouette, Silverbolt's eyes are normally gold but when Blackarachnia was killed and he uttered Tarantula's name in a vengeful manner they turned red, and most notably when Rhinox is reprogrammed as a Predacon his normally wise red eyes glow blood red for very good reason.
    • False Convoy in Transformers: Return of Convoy is distinguished from Optimus Prime by having red eyes instead of blue.
    • Shattered Glass, of course, reverses this, with the Decepticons mostly having blue optics and the Autobots mostly having red ones. Though there are a fair number of green, yellow, and other oddball optic colors on both sides, and Heatwave strangely has red optics despite being a nice guy, even by his fellow Decepticons' standards.
