Tears of Blood

"Nope, it's a stigmata with the bleeding of the eyes and the retina gone crazy-swirly with the twitching of bloody red cornea. The cornea-corn."

- Pillz-E, Neurotically Yours

Or pus, or slime, or icky black stuff... If something's coming out of your eyes and it's not salty water then you can bet your bottom dollar that something pretty bad is happening to you. The trope comes in two flavours, which are, oddly, created to have the exact opposite effect on the audience:

Flavour one is designed to freak them out, and is usually a sign that the person has been infected by some horrible virus, or is being killed by weird supernatural means. Eye trauma is one of the easiest ways to gross people out, and this method has the added advantage that the person can be "cured" without having lost their vision permanently. Alternatively, it signifies that the "weeping" person is in some way inhuman - or at the very least a candidate for supervillainy and somewhat demonic entities and characters.

Flavour two, meanwhile, is used to signify someone's death in a poetic and possibly even "beautiful" way, especially if the character is a tragic villain. This is far less common, and the aim is not necessarily to freak out the audience but to add a layer of sadness to a death scene. Mopey vampires are particularly fond of this flavour. The undercurrent to this kind of bloody tears is that the person doing the crying is in some fundamental way (be it biologically or emotionally) incapable of doing so through normal means- but is so overcome with emotion that they are doing so anyway.

Along these lines, statuary or paintings doing this with the first flavour can mean someone present is utterly evil (if the items are holy relics) or that the item itself is an Artifact of Doom. With the second flavour, it means the item is a holy relic that's "manifesting" itself this way in response to some tragedy/holiness, whether of its own or those present.

Comic Books

 * The "zombies" in Black Gas have completely black eyes and weep black tears.
 * The Corinthian in The Sandman sheds tears of blood when . Of course, since the Corinthian is an incarnated nightmare with razor-toothed mouths where his eyes should be, and in a past life was a serial killer who ate his victims' eyeballs (this incarnation is apparently firmly on the side of good, but no less creepy), this is really an example of both flavors at once. That said, this is actually a touching moment.
 * Amedeo gets these too, in the second part of The Corinthian: Death In Venice.
 * In Scare Tactics, the vampire Screamqueen cries these when she read Grossout's story about how he became a walking tumor.
 * In the 20th anniversary re-colouring of Batman: The Killing Joke, . Maybe.

Fan Works

Film

 * Flavor two example: in X 2 X Men United, when Lady Deathstrike is killed by being injected with molten Adamantium, she weeps silvery tears before dying.
 * Possibly a subversion, as the Adamantium leaks out of other orifices as well.
 * Flavor two example: in Kill Bill, when Gogo Yubari is killed with a nail through the head, she cries blood.
 * Flavor two was also used in John Woo's The Killer for two major scenes: one being the blinding-by-muzzle-flash of Jenny during the restaurant shootout that kicks off the plot, and the other being.
 * This trope is used in the movie One Hour Photo which, instead of being one of the two aforementioned flavours, is in fact distilled Nightmare Fuel.
 * The opening of Bram Stokers Dracula has Vlad, the title character, so crazy-angry at the death of his wife (since it was a suicide, which according to the religious doctrine of the age meant that she was damned) that he openly renounces God. He then takes his sword and stabs it into a stone cross, which bleeds. Then the statues in the chapel start crying blood. Then his candles start oozing blood. Then blood starts pouring out of the walls. Then Dracula drinks the blood and becomes a vampire. Narmtastic.

Literature

 * Older Than Print: Kriemhild from the Nibelungenlied weeps tears of blood after her husband Siegfried dies.
 * Authors and poets in the Heian era (for example, the Tale of Genji) were obsessed with this trope. "Crying tears of blood" in that time period was the melodramatic equivalent of modern English speakers "crying their eyes out," resulting in some romantic poems of the period reading a little differently these days.
 * 'Oh, my darling, my sleeves are stained crimson with blood at the thought of you...' Ew.
 * A phrase the Japanese borrowed from China. In Classical Chinese (and occassionally nowadays) the phrase "tears of blood" is up there with "having your intestines and liver disintegrate inch-by-inch" for expressing romantic tragic love.
 * In James Swallow's Warhammer 40,000 Deus Sanguinius, the advent of a Walking Wasteland daemon causes a psychic (on a spaceship, off planet) to weep blood.
 * Similarly, in Red Fury, when Serpens uses Nyniq to communicate with Caecus, she weeps tears pink with blood.
 * The Night Lords novel of the above setting has The Exalted, whose facial expression is frozen in a grimace by the Warp-induced mutations of his skull structure. The one time he is excited enough to force his mouth to contort into a smile, the muscular strain kicks his tear ducts into action, leaking "tears of oily [dark] blood".
 * The character Icaris, a Khorne Berzerker from the Warhammer 40,000 short story Honour Among Feinds by Dylan Owen weeps blood constantly because his opponents won't get to worship Khorne, just die in his name.
 * Ever wonder what happens when the Winter Queen of Faerie gets annoyed at a smartass who won't shut up and starts freezing the water in their eyes? Because Harry Dresden knows.
 * When the vampires of The Vampire Chronicles cry, their tears are blood.
 * In J.R. Ward's Black Dagger Brotherhood, sympaths (beings who can read and manipulate emotions that are feared and persecuted by the vampire race) shed tears of blood.
 * In L. Jagi Lamplighter's Prospero in Hell, Astreus would weep tears of blood if he could, for his exclusion from Heaven.
 * In Star Trek: Vulcan's Soul, a victim of Cosmic Horror the Intellivore ends up releasing these. It also overlaps with Psychic Nosebleed, seeing as the vast telepathic mind of the Intellivore has scambled the psychic receptors in the victim's brain.
 * Referenced in the Vampire Hunter D novel Pilgrimage of the Sacred and the Profane where Dhampir are described as crying tears of blood. D, being The Stoic doesn't give any corroboration.
 * For unclear reasons, most of the non-humans in Darren Shan's Cirque Du Freak series cry tears of blood.
 * In the Eighth Doctor Adventures novel Seeing I, gets a mild case of this when the  implanted in his left eye is activated.
 * In Teresa Frohock's Miserere An Autumn Tale, the Katharos bleed from the eyes after contact with the Fallen—sometimes the ears and nose as well.
 * In Stephen King's short story The Man in the Black Suit, Satan sheds them in the effort of swallowing a large fish.

Live Action TV

 * The Hands of Blue from Firefly use a futuristic device that causes ocular haemorrhaging and subsequent cessation of electrical activity in the brain. This device is used on Agent McGinnis and the Feds with nightmarish results in the episode "Ariel" after they admit that they have had verbal contact with River, whom they want to recapture.
 * They start to bleed from the nose and mouth, too. The device appears to kill by causing fatal internal haemorrhaging.
 * In Those Left Behind, the weapons used by the Hands are shown to be even more powerful, liquefying a man's entire body and leaving only a tattered husk of skin behind.
 * On NCIS, they receive a clue ahead of time from a serial killer, implying the next victim will cry tears of blood.
 * In Supernatural, the first sign of Bloody Mary's presence is that her victims begin to bleed from the eyes.
 * A statue of the Virgin Mary also started to cry blood to mark the approach of the demon Alistair.
 * The Wonder Twins from Heroes have a weird joint power; the woman, when stressed, begins to ooze black tears of poison. Anyone within a certain radius also begins to ooze the tears, but unlike her they subsequently die. The only way to stop the "infection" and revive those who have not been infected for long is for her brother (who is unaffected) to hold her hands and calm her down, at which point the tears turn into regular water. At the start of season two they did this around eighty times an episode; eventually Maya learned to control it herself. This has resulted in many fans making unflattering comparisons to...
 * The X-Files had an alien virus made of black oil that could control its hosts. The infected were shown to have black oil swirling on their eyes and would sometimes weep it too.
 * In the Doctor Who episode "Doomsday", a character who had been converted into a Cyberman cries oily tears as she turns on the rest of the Cybermen with a weapon that can kill them, meanwhile repeating the last thing she said before being converted.
 * This is how vampires cry on True Blood.
 * Merlyn Temple of American Gothic cries these, or at least her body does, during a lovely guilt-inducing vision which haunts the coroner of Trinity—since he was complicit in covering up Sheriff Buck's crime of "mercy killing" her. The accompanying Madness Mantra on the tape recorder, both as an artificially deep Voice of the Legion and a freakily speeded-up version, is the icing on the cake for this very disturbing scene. (You know the villain of a piece must be awful if this is the sort of thing the good guys do regularly to combat his plots.)
 * Someone's at the Door.
 * In Andromeda Beka once got these from overdosing on Flash, a highly addictive stimulant taken as eye drops.

Music

 * Ayumi Hamasaki's Brillante music video features this.
 * Grave Digger has song with the exact title and theme on the Best of the Eighties compilation.
 * Unsurprisingly, the Blind Guardian song "Blood Tears" mentions just that. (It's about the torture of Maedhros from The Silmarillion- that particular detail is not in the book itself at all, though.)
 * Nightwish with an early song, "Angels Fall First" ("Tears of blood, tears of fear..."). Also used in the music video for "Amaranth"—which involves a fallen angel crying blood through its blindfold. The imagery for this was inspired by Finland's "national painting."
 * This happens to Billy Corgan in The Smashing Pumpkins' "Try, Try, Try" video.

Tabletop Games

 * Ravenloft (2nd edition) used to have a magic item that looked like a valuable coin. It could be used to trick merchants, but every time the owner used it this way, he would begin to shed tears of blood that terrified anyone viewing him. The amount of time the Tears of Blood persisted depended on how big an amount of money you stole. The coin was cursed and very hard to get rid of—it bonded once you used it in a single scam, even once.
 * The Blood of the Martyr card from Magic: The Gathering. Or, for the "icky black stuff" version, several black cards such as Demonic Collusion and Sudden Spoiling.

Theatre

 * Shakespeare's Julius Caesar has a statue crying blood in a prophetic dream.

Video Games
""Poor, beautiful Carmilla... you will cry bloody tears before this night has ended.""
 * Later in the game, Heavy Rain has this happen to Jayden because of his overuse of ARI to desperately trying to figure out who the Origami killer is. At first it's assumed that its the drug Jayden is taking as the cause, but its seen in one of the endings that ARI is just as addictive. For reference: Blood out of nose: It's the drug. Blood out of eyes: its the ARI.
 * A teaser trailer for House of the Dead Overkill has the announcer saying that you'll "cry tears of blood from your own eyes!", or something similar.
 * Trailers for Resident Evil 5 show some poor guy being infected with something that makes him weep black, oily tears.
 * Flavour two example: In Phoenix Wright: Ace Attorney, the fifth case of the third game has
 * The Castlevania games have a number of examples:
 * First and foremost is the recurring villain Carmilla. She's been appearing since Simon's Quest, and while she doesn't personally cry tears of blood, she has a mask and a flying skull that do. For this reason, she's associated with one of the series' greatest musical themes, "Bloody Tears" (which also debuted in Simon's Quest); it's her theme in Judgment, for instance. Lords of Shadow gave all this history a Shout-Out in the narration:


 * Castlevania: Aria of Sorrow utilizes the villain-induced statuary variety in the castle's throne room, in which an enormous statue of a woman's face has cried a river of blood across much of the room, all in response to the presence of  However, this may not in fact have anything at all to do with the villain's presence, since a statue that continually cries blood seems like something Count Dracula would have had installed in his throne room simply for decor.
 * There's a statue in the X68000 version of Castlevania (later ported as Castlevania Chronicles) that cries tears of blood that turn into invincible skeletons. "Bloody Tears" is played here too.
 * There are similar statues in Castlevania: Harmony of Dissonance in the Skeleton's Den that also produce Blood Skeletons with their tears.
 * And in Castlevania: Portrait of Ruin there's a quest that requires fetching some holy water, which you get from a crying statue.
 * A statue that cries blood is also seen in one room in Castlevania 64. The blood turns into a blood monster.
 * The first use of "Bloody Tears" in a Castlevania game appears in the 1988 arcade game Haunted Castle. Dracula keeps a big painting of a blonde woman that weeps blood when Simon goes near it. This is possibly the origin of the song's name.
 * Siren, where all the shibito have tears of blood.
 * The Tears Of Lhys from Planescape: Torment were wept by the Mercykiller Lhys (naturally), falsely condemned for a crime and tortured to death; his innocence was only discovered after the fact. He wept exactly twelve tears of blood before dying. These became minor artifacts, and could be used by the character to permanently enhance one's Constitution score.
 * Also, the Nameless One weeps bloody tears after
 * The Sorrow, from Metal Gear Solid 3, cried tears of blood before and after his confrontation with Snake. It should be noted he is a ghost.
 * Solving one of the puzzles in Devil May Cry 3 results in two statues joining a third in weeping tears of blood.
 * The PlayStation 2 RPG Magna Carta: Tears of Blood has this too, obviously enough. And with a weird theme song, too.
 * Zero and Zero Two from Kirby's Dreamland 3 and Kirby 64 respectively. The former even attacks using this method.
 * The final boss of Skies of Arcadia has a special attack which starts with bloody tears coming down from his eyes.
 * Towards the end of Silent Hill 1, during a confrontation with Harry in which Lisa Garland discovers that, a cutscene shows her weeping blood before it begins to just ooze out from her skin.
 * Wallachia of Melty Blood. This is because his eyes are pools of blood, which is why he keeps them closed.
 * The original readme(and subsequent instruction manuals) of Doom read "Some of the ceilings in DOOM can smash you, making you cry blood."
 * In Daggerfall, being infected with vampirism (a .06% chance every time you get hit by a vampire (who, by the way, are obnoxiously powerful)) causes you to have a dream the next time you sleep in which a beautiful woman cries tears of blood.
 * The intro movie for the fifth chapter in Phantasmagoria shows Adrienne lying on her bed when suddenly tears of blood start streaming down her cheeks. It turns out to be a bad dream.
 * Daniella in Haunting Ground.
 * The Hunter of Left 4 Dead has blood all around his eyes, suggesting Eye Scream of some variety. (It's not clear whether he actually has eyes or not.) They don't bleed during the game, though.
 * Flavor 1 is used a lot in Trauma Team. This is almost always the point where the person bleeding from the eyes is about to die from the virus.
 * Sepperin Stage 2's stage title in Rosenkreuzstilette is "Bloody Tears". It even features a statue crying blood in the background of the Poltergeist boss battle at the end.
 * Subverted in Adventure Quest Worlds, where.
 * Jinpachi in his ending of Tekken 5.
 * Ishida Mitsunari cries Black Blood in his red path ending in Sengoku Basara. The fandom tends to joke about runny mascara.

Webcomics

 * The mannequin in Silent Hill: Promise once activated, sheds a single bloody tear.

 * Not completely sure this belongs here, but Dan also caused someone to pee blood. He'd run out of urine, but was so terrified that his body continued to pee anyway.
 * Subverted in Sluggy Freelance: when vampires cry tears of blood, that's simply analogous to humans crying normally.
 * The trolls of Homestuck cry tears that correspond to their blood colour, Word of God is that their blood dictates the colour of the rest of their bodily fluids, and tears just happen to contain the same pigment as their blood, rather than the actual blood, thus making this technically an aversion.
 * Played straight in a flashback scene which shows the day
 * In Penny Arcade, Tycho manages to inflict this on Gabe with a slide show.
 * Eerie Cuties: Virgins shed tears of blood in the reign of the vampire queen.
 * In the Oblivion-based online interactive story PREQUEL, Katia Managan has the natural Khajiit ability of darkvision.
