Sadly Mythtaken



""Now, Stephen, these are definitive, absolute facts about a myth?""

- Eddie Izzard, winning at QI forever.

When the writers take aspects from an intricate mythology or religion, twist their original meaning, and misuse them out of context for something far from its original purpose. It can be people, places, objects, anything up to and including God. Maybe they Did Not Do the Research, or maybe they did after all, but They Just Didn't Care, assuming that they didn't need to be accurate if they were using names and figures in a new context and purpose. It's not necessarily Faux Symbolism because often they don't even pretend to have intended some deep religious meaning behind it.

To be fair, many ancient sources don't agree on the specific interpretations of individual myths and legends, and many ancient writers would interpret them to prove whatever point they were trying to make. For example, most contemporary portrayals of the sorceress Medea have the deaths of her children be an accident, or a case of mistaken interpretation where the children turn out all right at the end. It wasn't until Euripides' play that Medea was turned into the purposeful murderess of her own offspring (even if she had the tiniest bit of sympathetic motivation for doing so), making this Older Than Feudalism.

This frequently happens to any god, no matter how benign, who happens to have any dominion over death or the underworld, due to Bad Powers Bad People.

In Western media, due to the Jesus Taboo and the like, pagan mythologies are more susceptible. The Japanese, on the other hand, have no qualms about bizarre portrayals of Christianity -- or Shinto.

When this kind of thing happens in real life, it's more commonly known as cultural appropriation and typically involves taking something (say, a myth or ritual item) from a specific culture or belief system and stripping it of all or most of its significance, Bowdlerizing it, and/or dumbing it down to make it marketable to the masses.

 * Pandora Jewelry. Sounds innocent enough... but if you know the actual myth of Pandora, it is HILARIOUS. The SparkNotes version? Woman opens tempting-looking box and unleashes evil upon the world.
 * Might be Fridge Brilliance if you know the myth. The original Pandora (her name means "all-gifted") was a Honey Trap: the gods covered her with finery, including gold and jewels, before sending her out to distract mankind.
 * In this case, it might be an inverted case of I Am Not Shazam.
 * The Volkswagen Phaethon, although named after a certain type of carriages of and cars, instead of directly alluding to the mythological character. Phaethon was the son of the Greek sun god Helios, who tried out his father's sun chariot, but did totally lose control, caused quite an high amount of destruction, and got himself killed due to this very early case of reckless teenage driving.
 * That cherub on the valentine? Not a cherub. A cherub has four heads and a flaming sword.
 * Really the flying babies ought to be "putti" (singlular: putto) but that term is hardly ever used outside of discussions of Renaissance art.

Anime & Manga

 * Pretty much any anime with any Christianity-related themes. In the West, it's the least exotic religion you can find. In Japan, it's incredibly alien and interesting. Sadly, nobody, by which means absolutely nobody, does the research, and just throws in a bunch of words and legends they found in The Bible. See also Anime Catholicism.
 * Ah My Goddess. The goddesses are named after the Norns (Verthandi, which contains sounds not available in Japanese, was not checked against the original Norse, creating "Belldandy" in the translation). Aside from having the three far more involved in human affairs than the dispassionate Norns would be, it is clear in Norse mythology that far from having to answer to a father-god, the Norns' judgment cannot be countermanded by any deity.
 * Particularly since Norns were the equivalent of the Greek fates, and in supernatural powers terms could only really predict the future, each one predicting its own personal strand of the future as they weave together. They were Jotuns (giants), though, so they could quite easily kick the shit out of any pitiful human that dared trespass on their well.
 * Not just the future. It is commonly belived Örlaganornirnar wove the web of fate. Urðr, whose name means that which has happened, wove the past, Verðandi, that which is happening, wove the present and Skuld, that which should happen, wove the future.
 * Well, seeing that the sisters, who are never referred to as Norns, are really only named after the Norns.
 * But it is mentioned that they are given powers aligned with the past, present and future, which is why in the issue where they begin to lose their powers, Urd starts getting younger, Skuld gets older, and Belldandy simply gets sleepy (Urd is going backward, Skuld is going forward, and Belldandy simply stops).
 * In Digimon Adventure, Centaurmon is the monster based on the Centaur that lives in a Labyrinth. One really wonders if the designers were instead thinking of the Minotaur.
 * In Aquarian Age, the "Age of Aquarius" is... a secret war that's gone on for thousands of years. As opposed to, y'know, a time of peace and prosperity that's recently begun or about to begin.
 * Or the Industrial Age or the Renaissance, for that matter. None of the hypothesized starts to the Age of Aquarius are thousands of years ago (1433 being the earliest outlier). The most cynical interpretation of the Age of Aquarius, though not very popular, happens to be...a world run by power-hungry elites who seek absolute power and the abuse of knowledge to win wars, though this interpretation only appeared after the series came out.
 * Leda: Fantastic Adventure of Yoko includes two characters named Lingam and Yoni, which are not only symbolic for Hindu deities, but refer to the male and female sex organs.
 * Saint Seiya did so with Greek and Norse myth.
 * Mythical Detective Loki Ragnarok ran away Norse myth and produced special results.
 * Kinnikuman blundered badly with this. Supposedly, there are lots and lots of gods out there of various planets, yet there's still Satan, and he's still the mastermind of all the Akuma Choujin/Demon Supermen. But Choujin don't go to Hell, they go to an underworld led by Choujin Enma. Then there's Ashuraman, who at least is correct in his depiction as a three-faced, six-armed individual. Of course, then we find out about his teacher, Samson Teacher who displays similar similar anatomy but has no reference to biblical Samson  at all.
 * In Cardcaptor Sakura there's a scene of Eriol expressing the spirit of church hymes... Except he totally didn't do the research, and winds up describing Shinto instead of Christianity.
 * Played for humor in Baccano where Isaac and Miria start talking about Romance of the Three Kingdoms but then begin confusing it with Jiraiya Goketsu Monogatari (he begins claiming the three characters are represented by a snake, frog, and slug) and then claims Liu Bei fought alongside Billy the Kid.
 * In the Light Novels, Isaac corrects Miria's notion that Frankenstein was the name of the monster instead of the doctor. The monster's name? Why, Mary Wollstonecraft Godwin Shelly, of course!
 * Yu-Gi-Oh with Egyptian mythology, paying only basic homage to it and basically crafting its own mythology with the Egyptian background being only color flavor at best. The God Cards are a mixed bag. The Winged Dragon of Ra is the least offensive, though Ra having a Dragon is alien to the mythology. Slifer in the US is the "Saint Dragon of Osiris", and Obelisk is named after a type of monument the Egyptians made. Also: ANCIENT EGYPTIAN LASER BEAMS.

Comics

 * The Mighty Thor. Thor was married to the goddess Sif, but that did not stop him from romancing a mortal woman.
 * The original Thor was a bearded Fiery Redhead, which was symbolic to the Norse. Marvel's Thor is clean-shaven and blond, which meant something completely different to the Norse. Likewise Sif's signatures were her long golden hair and demure demeanor. The Marvel version is a Xenafied brunette.
 * Loki is Odin's adopted son, rather than his blood brother. (And ergo he should be Thor's step-uncle)
 * Kind of justified in that Ragnarok is a cyclical event that results in a new version of the Norse gods appearing every thousand or so years, with change, both physical and familial, occurring each time they get, for want of a better word, reincarnated.
 * The Ragnarok Manhwa has the stoic Loki and the woman Fenrir, which people like to pair up. In mythology Loki was a trickster god and Fenrir was not only his son, but an absolutely gigantic wolf
 * Hell, Loki was a chick at one point!
 * Well he was a horse (in the original myth) at one point. A female horse.
 * Thor villain Amora the Enchantress is based on Freya, who was indeed an enchantress, but she was never evil. And what kind of name for a Norse goddess is Amora, anyway?
 * She was kind of evil.
 * DC Comics has this too. Hera as a kind, merciful goddess, Zeus as a wise and good-natured god, although this is within the parameters of how ancient Greeks saw them. More glaring is that Ares, who according to Greek mythology was the Amazons' ancestor and one of the gods they supposedly worshipped most, is their inveterate enemy in Wonder Woman.
 * Done a bit better in the 52niverse, which follows Greek mythology a lot more closely.
 * Jack Chick does this with every religion he writes about, including the one he's supposed to be promoting.
 * This is a large part of why people thought his work was an example of Stealth Parody at first.
 * In one issue of The Sandman, Loki is making a Badass Boast, and he references his children but claims that Fenrir is called "Sun-Eater". In Norse myth, Fenrir is destined to kill Odin at Ragnarok. His son Skoll is the one that eats the sun (his other son, Hati eats the moon).
 * Marvel Universe versions of Ares and Achilles both mentions fighting side by side at Troy. In The Iliad Ares was in Trojan camp.

Fan Works

 * Vampire Chronicles fanfic Rose Petals from a Vampire introduces an ancient Egyptian male vampire love interest for the Mary Sue. Since Enkil and Akasha in the books were identified with Osiris and Isis, the author thought it would be a good idea to name said vampire after another Egyptian deity, Nephthys. Good idea, except that Nephthys is a goddess.
 * It's not more wrong than identifying Enkil with an Egyptian god, which is right for the specific canon, but Enkil's just another spelling for a Babylonian god.
 * In Aeon Natum Engel Gendo lampshades the reputation of the Necronomicon as instantly driving the reader insane when it actually doesn't do that. Reading between the lines may cause this though.

Films -- Animation

 * This trope is particularly plentiful in Disney's Hercules, although it can be chalked up to Artistic License thanks to the writers Showing Their Work through a lot of literal Mythology Gags and trying to adapt Greek Mythology into a family film. Although this isn't too distracting unless Greek Mythology is Serious Business to you, these include:
 * Despite using the Greek names for everyone else, the movie uses the hero's Roman name - Heracles is his actual Greek name, a distinction more than a few people are hung up over.
 * He was not the legitimate child of Zeus and Hera, but rather the product of one of Zeus's many affairs with human woman. This, rather than a magic potion, is why he was not immortal.
 * He performed the famous twelve labors as punishment for having gone insane and killing his own wife (read Megara) and children because Hera struck him with temporary insanity to kill them, rather than to build a reputation as a hero.
 * That's right, Hera absolutely hated him, being the child of Zeus and another woman, and fought her hardest to get him killed. She was not in any way a mother figure.
 * The movie also places Narcissus on Mt. Olympus with the gods; he was not a god in the Greek myths. He was a mortal who was made to fall in love with his own reflection.
 * Pegasus has absolutely nothing to do with Heracles. He was captured and tamed by Bellerophon. And then they exploded, to make the story shorter.
 * Also the idea of having Megara be an independent woman is so wrong as to actually be hilarious, given that women were basically breathing objects in ancient times. She was given to Heracles as a trophy for defending Thebes and had, in no way, sold her soul to Hades. And, of course, as mentioned above, Heracles kills her.
 * Unlike the others, the change in Hades isn't even Disneyfication. He wasn't an evil god, (he was down nice compared to some of the other Greek Gods, Zeus in particular) nor did he have any antagonistic relationship with Heracles. In fact, he was vital in helping Heracles finish his last labor.
 * The Titans are also basically depicted as instead of the forebears of the Gods. They were pretty damn cool, though.

Films -- Live-Action

 * The Mask refers to Loki as the Norse "god of darkness". Loki is not a god of darkness, or arguably a god at all, for that matter. (To the extent that he's anything, he's a herald from the gods, not of them.) The closest thing to a god of darkness in Norse Mythology is Nótt, the personification of the night.
 * In Son of the Mask, Loki is Odin's son (in the Norse myths, he's actually a Jotun fostered by the Aesir, of which Odin is the foremost). And the creators apparently didn't even bother to research the series' own "mythology", presenting Loki and the Mask as separate entities, while the original film established that Loki was trapped within the Mask.
 * Clash of the Titans makes so much hash of its source material that an exhaustive catalog of the errors would be a challenge. Considering that the errors begin, in a way, with the title of the film, this should not be too surprising: the film considers a Titan to be just about any large, disagreeable monster such as the Kraken (which is Scandinavian, anyway; the creature depicted by the movie is actually supposed to be Cetus) or Medusa, while in Greek mythology the Titans were an early group of gods. The main storyline follows the main events of the Perseus myth, but also muddles together unrelated stories, such as Pegasus, as well as nonsensical elements that appear nowhere in any of the cobbled-together myths, such as a mechanical owl.
 * The inclusion of Pegasus is especially ironic given that that the original winged horse sprang from Medusa's remains.
 * Ray Harryhausen even acknowledged the fact that the Kraken never appeared in Greek mythology. Cetus, the sea monster that Perseus killed in the myth was more akin to a sea dragon. Ray simply didn't want to create another dragon, so he decided to use the Kraken, a far more unique menace. It was purely an aesthetic decision, although it doesn't at all resemble a squid or octopus like the mythological Kraken.
 * The Remake has Hades as the evil "God of Hell," who is trying to (you guessed it) Take Over the World.
 * Not to mention that Medusa's lair is apparently in/near the Underworld, Perseus hated all the gods,, and Pegasus isn't the unique child of a very unique mother, but rather a name for winged horses in general...a myth-loving person may cry like a baby by the end of the movie.
 * Sci Fi Channel's original monster movies based on mythological creatures might do anything. Their depiction of Cerberus is especially bad, what with it guarding a Hun weapon in Romania instead of the gates of a Greek underworld, and everything...
 * Almost any Western movie ever, when it comes to Kali, the Hindu Goddess of death, destruction and disease, but also the Goddess of mercy and forgiveness and good health. More on her on That Other Wiki. Indiana Jones and The Temple of Doom? Check. Stranglers of Bombay? Check. The Golden Voyage of Sinbad (animated Kali by Ray Harryhausen)... Check. Shiva more raises confusion, maybe because theoretically he's most capable of destruction, but very rarely cares to blast anything, when compared to other deities.
 * To oversimplify the issue, Durga fought demons so strong she has to be reborn in the form specifically prepared for this task, while Kali slaughtered lesser foes. Kali is also a mother figure -- which makes her sort of "universal Mama Bear," but then it's only to be expected that she can be utterly horrifying and widely admired.
 * Mostly, these confusions arose because Hinduism itself (as most Europeans know it) is a result of several transformations. First was Vedanta introduced in VIII century AD, last was "Hindu Reformation" of late XIX - early XX. For one of local interpretations, there's guy who grew there and spoke their language and his Shiv and the Grasshopper, where neither Shiv nor Parbati are portrayed as anything anywhere near "gods of destruction," but "Shiva the Preserver" was invoked. BTW, he's blue-necked because he drank primal poison capable of wiping out the rest of the universe. But if you see Trimurti as personification of Guna (3 flavours of prime driving force), it makes sense that face of Tamas is a pinnacle of body's force ("food giver," Great Ascetic, creator of dance) and raw force as such (ultimate not-to-be-trifled-with but not very actively dangerous power, both "Destroyer" and "Preserver" depending on situation)... and, well, have such an outstanding "significant other."
 * The villains in Temple of Doom were Thugee (although highly distorted ones, no Thug would be stupid enough to act openly), and at least some of the real members of the group claimed to worship Kali as death. The problem is, the movie treats this as being the correct and only interpretation of Kali, who is actively evil and makes people Brainwashed and Crazy with her blood.
 * For further mythtaken-ness, The Temple of Doom has Shiva as the one true God of Hinduism and Kali as his enemy.
 * What may confuse people more is that there is an entirely different figure in Hindu mythology named Kali, who actually is evil. It doesn't help that Indian civilization goes back a really long way, and people there commonly name their kids after gods, and they have quite a lot of kids and quite a lot of gods.
 * The killer Kali statue from Golden Voyage of Sinbad may be an in-character example, as the evil wizard who controlled it showed few signs of being Hindu, although he did recognize what goddess the statue represented. Animating the thing was just a convenient way for him to impress the local savages and create a many-sword-wielding Mook.
 * The green-painted savages who worshiped the statue weren't intended to be typical of Kali-worshipers either; they're just a Stone Age tribe that'd moved into the ruins and adopted the statue as a deity because it looked impressive.
 * The plot-driver in Raiders of the Lost Ark is that the Ark of the Covenant is some sort of magical weapon. Which, suffice it to say, does not quite match the description found in the Bible.
 * In one instance in the Old Testament, the Ark bestowed blessings on the man who kept it in his house. The film turned this up to eleven and gave the Ark properties similar to the Spear of Destiny. The bit about the Ark killing those who disrespected it is Biblically accurate however.
 * Neither does the "Holy Grail as granter of eternal life" seen in the third movie. The writers came with that after toying with the idea of having Indy retrieve the Holy Grail in the Action Prologue and then going to look for some version of the Fountain of Youth in the movie proper. Somebody suggested to mix the two, and the rest is History.
 * The film Godzilla, Mothra, King Ghidorah: Giant Monsters All Out Attack has King Ghidorah as sort of a variation of the Yamata No Orochi. However, Orochi has EIGHT heads and Ghidorah only has three. The film explains this by stating that Ghidorah hasn't matured enough yet to have grown all eight heads.
 * Averted with the film Godzilla vs Mechagodzilla which actually does a fairly accurate representation of the Okinawa mythologies of the Shisa in regards with the daikaiju King Seesar.
 * Evil Bodhisattva in Big Trouble in Little China. Yipes. Not all Bodhisattvas are very nice, though evil is a pretty strong stretch.
 * Mission Impossible II: Anthony Hopkins's character mentions that Spaniards honor the Saints during the Holy Week of Seville by burning their effigies. He's probably confused with the Fallas of Valencia, a different city where effigies of celebrities and politicians are burned -- nothing to do with religion. This character is shown to be a jerk, but he should know the name of the city he's visiting, and people were in fact burning some effigies in the streets of Seville for some reasons we Spaniards cannot even imagine.
 * Another confusion happens in a second Tom Cruise movie, Knight and Day (which at least filmed a couple of scenes in Seville). Nope, San Fermín is not the national holiday of Spain or something like that. It's a local holiday in Pamplona only.
 * The Mummy Returns has Anubis as a "dark god". To make it even worse, someone was described as selling his soul to Anubis. Anubis carries all the souls of the dead to the underworld, but he isn't in possession of those souls, nor is there any equivalent of hell in the Egyptian afterlife (undeserving souls are simply fed to a monster; yes, it sounds awful, but think about this: it's not eternal).
 * To clarify, the closest thing to a "dark god" in the Egyptian pantheon was Set, who was still a figure of benevolent worship, and not completely evil, depending on which myth you read, although he was pretty much universally a jerkass, sometimes acting as Ra's bodyguard, only to turn around and murder Osiris (although he recovered), only to turn into Horus' Butt Monkey for a while while acting Chaotic Stupid (seriously, trying to make a canoe out of stone?).
 * The first film also has Imhotep being terrified of cats, due to the claim that they are the guardians of the underworld. The Duat (underworld) in the actual myths was guarded by monstrous serpents, and someone in Imhotep's position, having assisting in the murder of the Pharaoh, the living incarnation of the sun god Ra, was guilty of the single worst crime imaginable, and there was a punishment reserved specifically for people who had committed this particularly horrid type of blasphemy: to be tied with one's arms behind one's back in the underworld in a position designed to cause terrible pain while having a multi-headed serpent eternally breathe fire into your face.
 * "The Book of the Dead" is not a physical book; it's a collection of death-related texts from tomb walls and coffins (and it's really called "The Book of Coming Forth By Day"). Plus, even if it were a single artifact, it wouldn't have been the codex-style "book" seen in the film, as that format wasn't used till the late Roman Empire.
 * The only way to enjoy the first two Mummy movies is to turn off every neuron you have that knows anything about actual Egypt. In the third one, you need to turn off China as well.
 * Xanadu has Hera and Zeus claim that, as gods, they are above emotions. Yes, the god who would hit anything with a vagina (and Ganymede) and the goddess whose vengeance for being cuckolded would make Lorena Bobbitt cringe claim to be emotionless.
 * Name a Mesoamerican god. Quetzalcoatl. Name that only one thing you know about Mesoamerican religions. They practiced Human Sacrifice. So that's it! You'll place the climax of your movie on a scene featuring a human sacrifice to Quetzalcoatl! Except that's just wrong. Quetzalcoatl did not demand human sacrifice. He allegedly disliked it, and was "fed" on birds and butterflies only. Better candidates for your classic Religion of Evil scene would be the god of war Huitzilopochtli or the god of water, Tlaloc. A lot of movies like Apocalypto and other media botch this (notice Apocalypto takes place in Mayan lands, and Quetzalcoatl is thus referenced by his Mayan name, Kukulkan).
 * More than that, Aztec priests took the names of their gods, and one named Quetzalcoatl tried to end the human sacrifice. He was executed as a heretic for this, naturally.
 * The Exorcist: Admirably, instead of choosing a pagan god to turn into a demon, they used an actual evil spirit from Mesopotamian mythology as the one who posseses Regan. However, Pazuzu was the exact wrong choice, since out of all Mesopotamian demons, he's the only one known to protect children (mostly against his wife, Lamashtu, who would have been a more appropriate choice).
 * It's possible, of course, that this would have been deliberate on the part of the author, if he wished to tap into the common belief among some Christians that the various pagan deities might actually have existed, but were actually demonic deceivers. In that case, the 'protects children' itself would have been a deceit.
 * Dogma features muses, and an angel named Loki, but since in the Dogma-verse, humans can imagine anything about cosmology and it becomes true...
 * Only if it has a papal sanction.

Literature

 * In The Chronicles of Prydain, the characters have names from Welsh mythology, and like other Hijacked By Jesus examples, the name of the god of death is given to a Satanic character. Comparatively, the honorable Aragorn is named Gwydion, who was actually more like Loki/Hermes in the mythology. At least Lloyd Alexander admits he's playing fast and loose with the Welsh mythological canon. To quote him: "Prydain is not Wales--not entirely, at least. The inspiration for it comes from that magnificent land and its legends; but, essentially, Prydain is a country existing only in the imagination."
 * Michael Chabon's novel Summerland takes place in a world that cheerily mashes together Native American and Norse mythology. This leads to the reveal, utterly brain-breaking if you know your mythology, that Seriously. (And for its next trick, the rules of the Universe are based on those of baseball).
 * In Immanuel Velikovsky's supposedly nonfiction book Worlds in Collision, he put forth a pseudoscience explanation for various cataclysms based on the idea that Venus was the Roman version of the Greek Athena. In fact Venus is the Roman equivalent of Aphrodite, a fact that even bad pop song writers should be able to tell you.
 * Early in his writing career, Robert E. Howard realized he was horrible at making up names. So the Conan the Cimmerian stories are liberally sprinkled with historical and mythical names for characters and places that don't necessarily relate to the narrative context.
 * In some cases (particularly with the Aesir and the Vanir tribes) that what we know of ancient mythology is actually half-remembered tales of real events from the Hyborean Age. So in the Conan universe, we're all guilty of this trope.
 * Justified in Fred Saberhagen's Books of Swords trilogy, as, while Vulcan is, as pointed out in the essay at the end of the first book, more like a Norse Jotun in personality than the Vulcan of Greco-Roman myth,
 * Herman Melville betrayed his (or his character's) ignorance of Greek mythology when, in Moby-Dick, he had Captain Ahab compare the ship's blacksmith to Prometheus.
 * Ray Bradbury's The Halloween Tree features a downright painful mangling of Egyptian mythology. It equates Osiris with Ra, as well as equating Osiris' resurrection with both the cycle of day and night and the changing of the seasons.
 * One can forgive Dante's merging of Greek and Christian takes of the afterlife and mythology in his Divine Comedy as creative liberty, but one cannot forgive him for his use of the centaurs in the outer ring of the seventh circle of Hell, for one distinct reason: he put Chiron, a Defector From Decadence and revered healer and sage, as the leader of the centaurs driving the damned back into the boiling blood river, and put Nessus, a notorious Complete Monster known for raping Hercules' second wife and tricking her into poisoning him to death, as the one the one who helps Dante and Virgil across the river. Apparently, all Dante ever knew about them was that they were both centaurs and Nessus carried Herc's wife across a river before raping her.
 * Consider also that: 1) Nessus helps Dante and Virgil only because he is ordered to -- by Chiron; 2) Dante had no direct access to the original Greek myths and knew them only through Latin authors.
 * He should know enough about Chiron from Statius' Achilleid, though -- and Dante was fond enough of Statius to retcon him into a Christian.
 * Consider further that in Dante, people are in Hell because God wants them there. Easing their suffering would be an evil act, approving of their suffering is just. Chiron being the leader of the centaurs in administering the punishment could actually mean that he is closer and more obedient to God.
 * You can blame Lafcadio Hearn for the fact that any Westerner who's heard of the mujina probably has it confused with the noppera-bō (or "faceless ghost"), and for mislabeling the nukekubi as rokuro-kubi.
 * Bridget Wood's Celtic fantasy novels. But hey, it replaces all semblance of plot with bestiality and gory rape, so that's alright then.
 * Some criticisms of Twilight actually have the criticizers run afoul of this just as much as Stephenie Meyer did. No, Vampires did not sparkle, but has anyone (who hasn't played Ben Jordan) who says vampires couldn't go out into the daylight ever heard of a Strigoi? Or even read the Bram Stoker novel? Not to mention, some of the werewolf myths actually were just men who shifted into wolves.
 * In Twilight, Meyer describes varacolaci as being "a powerful undead being who could appear as a beautiful, pale-skinned human", while they are more famously known as wolf demons that cause solar and lunar eclipses by swallowing the sun and moon respectively. They also appear as dry pale-skinned humans, not beautiful. In Breaking Dawn and Midnight Sun, Meyer cites the incubus and succubus as vampires who are known in mythology as being promiscuous and impregnating human women. Both of them were demons who were believed to be the cause of nightmares and wet dreams. Also in Breaking Dawn, the cleaning lady at Bella and Edward's honeymoon site believes that Edward is a "libishomen", described as "a blood-drinking demon who preys exclusively on beautiful women". In reality, lobishomen (the real name of the libishomen in mythology) were monkey-like werewolves.
 * One of those is actually justified; Edward implied that myths about incubi were made up by humans based on vampires like him. The other cases are valid, though, and there was also a mention of 'actual' werewolves that operate on 'full moon and silver bullets' logic. The silver bullets are more of a Hollywood concept.
 * Related to the above, the fandom of Dracula, rather than the author, are widely guilty of this. Adaptations have flanderized sunlight into vampire kryptonite, but Mythology Marches On, and Stoker's vampires are merely weaker in sunlight. The original Dracula is also destroyed by a knife through the heart rather than a stake. Sharp steel or iron objects like needles or knives are effective vampire kryptonite in Slavic mythology, yet adaptations, sequels, and even "scholarly" annotated versions of the novel jump on the lack of a wooden stake as proof that Dracula is Not Quite Dead.
 * The characters of Atlas Shrugged use the idea of Atlas holding up the celestial sphere as a model of great men being constrained by the demands of lesser beings. If Atlas ever got tired of the weight, all he'd have to do is shrug it off and it'd be the end for them, right? Well, in the original myth, Atlas was holding up the sky, and he was doing so at the command of the gods, as punishment for siding with the Titans in the Titanomachy. For added giggles, this had the side effect of preventing Gaia from doing the nasty with Ouranos and creating more problems for the gods. Additionally, shrugging off the weight without someone else to hold it for him (like Heracles in one of the myths) would only result in Atlas and everyone getting the sky dropped on them. Ironically enough attempting to "Go Galt" and separate yourself from the rest of society in real life can have similar messy consequences since many of those other beings are responsible for ensuring that "great men" have nice things (Who Cleans Galt's John?). In any event, Atlas was eventually turned to stone by Perseus anyway, making the shrugging a moot point.
 * Harry Potter novels tend to attach the names of mythological creatures to beings unrelated to them. For example, "boggarts" are small, dwarf-like creatures, not shapeshifters.
 * Snape also says that a Kappa is a Mongolian beast in an offhand comment, correcting a student in one book. However, Fantastic Beasts and Where To Find Them states that Kappas are actually Japanese. Harry then lampshades this, by writing "Snape hasn't read this book either" next to the article on Kappas.
 * In 'Hush, Hush'', the characters constantly turn to the Book of Enoch as a reference for the rules of fallen angels. This is reinforced by the fact that the only fallen angels we see are ones who procreated with humans to create the Nephilim (as recorded in the Book of Enoch). According to the book though, the angels did not fall because of lust for human women, but because they were supposed to watch over the Garden of Eden and instead tempted Eve with the apple so that they could lay claim to Earth.
 * In Petronius's The Satyricon, Trimalchio narrates a skit about the Trojan War to his dinner guests and completely butchers the mythology. This was a satire of nouveau riche merchants, whereas proper aristocratic Romans would've received an education in Greek literature and philosophy.

Live-Action TV

 * While Stargate was arguably already pushing the "liberal" application of Egyptian mythology too far, Stargate SG 1 pushed it even further -- and not just Egyptian, but many mythologies all over the world, shoehorning them into the premise of aliens impersonating gods. Of course, within its universe, it's the religions that are memetic mutations of the events that "really" happened, not the other way round.
 * Even there it's a little unclear. Sometimes the Goa'uld seemed to be impersonating or taking on the roles of mythological figures that existed before those Goa'uld came to Earth, while other times the Goa'uld seemed to be using their own names and identities which happened to inspire the myths we now know. That might be Depending On the Writer, or since the Goa'uld came to Earth now and then for thousands of years, it might just vary depending on the individual Goa'uld. The Asgard, though, unambiguously are open about their names, identities and goals, and their actions happened to inspire the Norse myths.
 * The Asgard used holoprojectors to disguise that they were small and grey, though. SG-1's position on the Goa'uld seems to have shifted over time. It was pretty clearly a case of the Goa'uld being the inspiration for mythology, but characters started quite pointedly saying the Goa'uld assumed the roles of gods. (Presumably someone became uncomfortable with the unfortunate implications for well, every religion in the world).
 * In the Season 1 episode "Thor's Hammer" (The One Where We Learn of the Asgard), Daniel says that Thor had a hammer called, well, Thor's Hammer. The problem with this is that it was actually named Mjolnir, and is probably the second most famous named weapon in the West (a distant loss to Excalibur).
 * And sometimes it's an axe.
 * That might have been a matter of No Pronunciation Guide; The Matrix faced a similar problem where one of the hoverships was named The Mjolnir, but everyone called it The Hammer because no one on set could agree on how to pronounce Mjolnir.
 * Despite having approximately the same relationship to myth and history that spray cheese has to food, Hercules: The Legendary Journeys and Xena: Warrior Princess had a pretty good grasp of the personalities of the gods, spirits and other critters they appropriated from various mythologies. Zeus was a philandering jerk; Ares was bullheaded, aggressive, not too bright, and rotten to the core; Thor was bullheaded, aggressive, and not too bright, but at least well-meaning; and so forth...
 * While Xena usually has a (relatively) good grasp on mythology, the episode "Girls Just Wanna Have Fun" included Bacchus as a demon lord of some kind, his Bacchae followers (more correctly Maenads) as vampires, and, worst of all, dryads as skeletal harpies. What were they thinking?
 * The makers of Hercules took a look at Typhon – the biggest and most dangerous monster in all of Greek mythology, the greatest enemy ever faced by Zeus and the Olympian gods – and decided to make him into a dim-witted but lovable oaf. Apparently having him as a villain would have been just too awesome or something.
 * McMillan and Wife did an episode where Sally is stalked and kidnapped by "Satanists". They figure out who the bad guy is because he makes references to ancient Egypt -- ancient Egypt being, according to the writers, the origin of Satanism. Eventually they learn that the stalker believes Sally to be the incarnation of an Egyptian goddess named Serena. Not only is the Egyptian mythos totally unrelated to Satanism, and "Serena" not an Egyptian goddess, but "Serena" isn't even an Egyptian name!
 * In Buffy the Vampire Slayer, the Halloween episode is notorious among certain circles for portraying Janus as a god of chaos. Nothing could be further from the truth; while the "division of self" does fit the idea of people and their costumes becoming one, Janus could better be portrayed as a god of Order, not Chaos, especially in his role as god of portals, doors, and gateways.
 * Another episode involved invoking Diana for a spell meant to make someone fall in love, or at least lust, with someone else. Part of her domain was virginity. Of course, this could be why the spell went so horribly wrong.
 * Supernatural: The show started out with urban legends and was very faithful to them. It started doing the same kind of 'square peg into round hole' approach to its monsters-of-the-week as Charmed around the same time it started Going Cosmic and incorporating all kinds of mythology, no matter how awkwardly they fit the series.
 * One of the most talked-about examples is the episode "Hammer of the Gods", in which all pagan (and Hindu, who are treated as pagan despite not being so) deities are man-eaters. It's vaguely interpreted that gods feast on human flesh when there's little faith left to sustain them... in which case, it's surprising to hear that all of India embraced Islam at some point in the history of the Supernatural-verse.
 * Archangel Gabriel is strangely a Trickster Archetype.

Myths & Legends

 * Snorri Sturluson's Prose Edda is one of the main sources of Norse Myth. However, Snorri wrote them down in the 13th century just as Europe became obsessed with the Greek myths, and after Christianity had largely replaced the old beliefs. So, to make the legends respectable, he claimed that the Norse Gods were actually the heroes of the Iliad, who came north after the events described by Homer, and, because the Greeks were so great, they were able to convince the locals that they were gods. In one of the most hilarious trees in the Epileptic Forest, he claims that because Thor was sometimes referred to as Asa-Thor ("The Aesir Ás, Thor"), that he was clearly Hec-Tor. (Never mind that Hector dies at the end of the Iliad.) Okay, half the countries of Europe were claiming descent from some hero or race of Greek Myth at that time - the Britons claimed to be descended from someone called Brutus who, after the Trojan war, got swept out to sea and ended up in Britain; The Declaration of Arbroath says the Scots were descended from the Scythians (I can only presume because Kenneth Mac Alpine played the same "Invite the chieftains to a party, get them drunk, then slaughter them" trick on the Picts that was played on the Scythians in Herodotus: there's very little other mention of the Scythians). So why not claim you're descended from every single Greek hero?
 * He also was under a little pressure to point out that recording pagan myths didn't make him any less of a God-fearing Christian.
 * Texts such as the Lebor Gabala Erenn are essentially the Celtic(mainly Irish) equivalent of the Eddas; and also have a rather incoherent Christian time line tacked on. Interestingly, the author of the Book of Leinster was so afraid of being branded a heretic after listing the Tuatha De Danann that he added the disclaimer "Although the author enumerates them, he does not worship them."
 * Norse myths continued to suffer: In Victorian times, the Poetic Edda -- an ancient collection of the Norse heroic legend -- was re-discovered. Richard Wagner made them into operas, threw in some German myths, and we get the Ring cycle, which... well, it resembles the originals in places, but it's essentially a complete rewrite of the myths.
 * And Wagner's Spiritual Successor to the Ring cycle, Parsifal, is the myth of the Holy Grail remade in the image of the Bayreuth Theater. At least Wagner didn't invent the Sadly Mythtaken Arabic etymology of Parsifal's name.
 * Wagner's Ring is something of a cross between two versions of the same story, and Wagner's own personal sensibilities (the stories being the Middle High German Nibelungenlied and the Scandinavian Volsunga Saga) It is very likely that the two stories share a common origin. Both purportedly feature the Burgundian realm by the Rhine and feature Attila as a minor character (Etzel in the Nibelungenlied, Atle in the Scandinavian version).
 * Any later work that describes Circe as a "sorceress." In The Odyssey, she is a goddess (although presumably a minor one, since she lives on her island rather than on Olympus).
 * She is daughter of Helios, the Sun god, and Perse or Perseis, one of the thousands of daughters of the Titans Okeanos and Thetys, and thus the daughter of a major and a minor deity.
 * Pick any media where Anubis appears. The mistaken uses of Anubis as evil, tremendously powerful, or the chief god of death in the Egyptian pantheon are so rampant and constant that they qualify as perhaps one of the most egregious examples of Critical Research Failure in current culture. To be specific: Anubis was the guardian of the resting places of the dead, and the judge of dead souls. These were his only roles, making him a minor deity in the Egyptian pantheon. The chief deity of the dead was Osiris, and nothing to do with death was inherently evil. In actuality, given his role as guardian Anubis could be considered one of the more benevolent deities of the Egyptian pantheon, so long as you don't mess with his charges.
 * An interesting aversion was the Disney's Gargoyles cartoon. Anubis makes an appearance, and has to repeatedly point out that he isn't good or evil. He does what he does, which was, in the Gargoyles universe, wielding power over who lives and who dies, but that power was applied indiscriminately. Though surprising for a Disney cartoon aimed more or less at younger viewers, it wasn't all that odd for Gargoyles to try and make a point like death isn't inherently good or evil.
 * Age of Mythology averts this. Anubis appears as a minor god, and isn't so much as mentioned by name in the campaign. The Guardian Statue that appears briefly, bears some resemblance to him, and the protagonist's former archnemesis, who appears in two flashbacks, where he's killed, dressed like his followers, but that sums up all references made to him in the story. The god of the dead is Osiris, and he's on the heroes' side. The God of Evil who aids the villains is Set.
 * Another interesting quasi-aversion is Stargate SG 1. While the semi-Ascended Goa'uld Anubis is in fact evil--indeed, the Big Bad, and a pretty scary one at that--Anubis is simply the worst of a bad bunch, all of whom pose as ancient gods, and all of whom are evil (except for the Tok'ra rebels, of course), regardless of the alignment of the mythological gods: Heru'ur, another antagonist, is a stand in for the unambiguously-good Horus; the same goes for Ba'al (who is unquestionably evil before his Character Development and Enemy Mine). To the writers' credit, they have Daniel Jackson occasionally try to remind us that the Anubis the Egyptians believed in was not evil.
 * It's important to point out that Egyptian beliefs differed from nome to nome, and suffered MASSIVE retcons as time went by. Anubis was originally the God of the Underworld, but when the cult of Osiris (who was originally a water deity) rose to prominence, they retconned Anubis as the Embalmer. They did the same thing to Horus and Set, who were the guardians of Ra's solar barge, and turned them into Osiris' son and evil brother. Mythology marches on.
 * Just about every Western work with Kali (the Hindu night-goddess) in it. Mostly this is due to exaggerated stories about the Thuggee cult and general Western misunderstanding of Hindu deities. Several Hindu deities assume terrifying forms to slay demons. One Hindu writer tried to explain this idea by saying that Kali can be like a cherished watchdog: to you, the dog will be cuddly and loving and a great friend, but furious and dangerous to anyone they think might harm you. Moreover, Kali's chopping off of heads symbolizes her chopping off bad thoughts and inflated egos, and her chopping off of hands symbolises her cutting off bad deeds.
 * Strangely enough, World Wrestling Entertainment has been doing their part to correct this misconception (albeit unintentionally) by crafting a Heel Face Turn for the Punjabi wrestler "The Great Khali" in 2008 and having him fight Kane, who is literally known as "The Devil's Favorite Demon."
 * While he is often treated as a Buddha (a person who attained enlightenment), and sometimes as an incarnation of Maitreya, many depictions of Budai (also nicknamed the Laughing Buddha) usually by people with little to no knowledge of Buddhism, will treat him as THE Buddha, the deity Buddhists worship. In reality, the Buddha (Siddharta Gautama) is not worshiped as a deity at all, but rather revered for his wisdom and as an example of enlightenment.
 * Some people do worship Buddah as a god. Most don't claim to be Buddhist.
 * An apocalypse is simply knowledge acquired, or a revelation if roughly translated. If talking of the Apocalypse from The Book of Revelation specifically, then that's supposed to be the end of the world and any so called Post Apocalyptic setting that takes place where it happened is sadly mythtaken.
 * For that matter, the apocalypse itself. It was supposed to be an allegory for the fall of the Roman Empire, rather than The End of the World As We Know It.
 * On that note, "Armageddon" properly refers to the place of a battle during the end of the world, not to the end of the world itself. The name means Mount Megiddo, a place in Israel inhabited from 7000 BC to 586 BC, with the area resettled by a kibbutz in 1949 AD.
 * Whoever started the idea that the Maya calendar predicts an apocalypse in 2012 did not do the research. 2012 is the umpteenth anniversary of the creation of the universe in the Maya calendar, the end of one bak'tun (394.25 years) and beginning of the next one. It has nothing to do with the world ending. If ancient Maya calendars stop at 2012, it's because it was still a long way off and they weren't trying to create an infinitely long calendar.
 * Modern depictions of Classical Mythology usually make the Titans a species of Giant. But in the original Greek myths the Titans are all gods, not Giants. Only in the last years of Classical antiquity did writers start getting them confused with the Giants, because both fought wars against the Olympian gods, and both were defeated. In fact some Greek gods, including some with significant worship such as Rhea and Hecate, were considered Titans who sided with Zeus in his war against the other Titans. The sun god and moon goddess are also Titans.
 * The notion of "foo dogs" is a Western misconception, based on the mis-identification of Chinese guardian lion spirits' statues as canine. The existence of several Asian dog breeds that were named for, and bred to resemble, such divine leonine protectors has only exacerbated the misconception.

Tabletop Games

 * Dungeons and Dragons does this quite often, usually because it runs on what's fun, interesting, and useful rather than what's accurate (especially since, given these are other worlds, they can take refuge in In Name Only).
 * D&D has angelic beings known as Asuras and Devas. Both of which are the names of benevolent spirits... But in different cultures (Iran and India respectively) both which use a variant of the OTHER name for a class of EVIL spirits.
 * The angels themselves lack faces, at least in 4th edition, where Devas are metal-skinned humanoids with hundreds of past lives.
 * There is a monster called a Medusa, which is ye olde snake-headed woman; in the original mythology, Medusa was an individual's name, and she and her sisters were collectively called Gorgons. D&D has creatures called "gorgons," but the mythic creature they most closely resemble is the catoblepas.
 * Tiamat, the goddess of evil dragons, is named after the Babylonian figure that -- despite being the mother of dragons and serpents, as well as most other creatures -- never had a serpentine appearance, much less that of a multi-headed dragon.
 * Although this specific depiction was invented by Dungeons and Dragons, and helped popularize the idea that she's a dragon, the idea of her as a dragon or sea serpent does predate Dungeons and Dragons. It mostly owes to the specific mention of her as the mother of dragons and sea serpents in the Enuma Elish -- but this was just because she was generally the mother of monsters.
 * The writers of The Real Ghostbusters had one Mesopotamian-mythology-themed episode in which Marduk fights against Tiamat--and Tiamat had the form of a five-headed dragon! It's unlikely (but conceivable) that this was a Dungeons and Dragons reference as such; more likely, someone was familiar with the Dungeons and Dragons version of Tiamat and thought that the idea of Tiamat having five heads was authentically a part of the historical Mesopotamian version of the deity.
 * Tiamat of the Sumerians and later Babylonians is often conflated with the Ugaritic god Lotan (in The Bible, God defeats both of them). Lotan was in fact depicted to be a multi-headed dragon and sea god, who was defeated by Baal Hadad.
 * Bahamut, the benevolent god of good dragons, is similarly named for the giant fish/whale/turtle (depends who you ask) of Arabian myth, which carries the world on its back. Think 'Behemoth'.
 * Some people have also been getting angry at Final Fantasy for spreading the image that Bahamut was a dragon. Lies. Bahamut's been listed as a benevolent dragon in Dungeons and dragons canon since the 70s - Final Fantasy was just based off of Dungeons and Dragons second edition.
 * A minor interesting note, though, is that some time ago, D&D added a character named Kuyutha, Exarch of Bahamut (his champion of sorts), whose name is based on Kujata, the giant bull who rests on top of Arabian Bahamut.
 * The lamia is a monster that, depending on the edition, is: a woman's upper body with a snake's tail instead of legs; a female lion-taur; or a woman who can turn into a swarm of insects a la the Mummy. In Greek mythology, Lamia was a woman transformed into a child-killing demon, and later a whole class of quasi-vampiric spirits were called lamiae (singular lamia).
 * Lamia also got confused with the Kabbalistic Lillith, a different child-killing demon, at some point.
 * Just to keep score, the snake-woman's real name is "Echidna," the liontaur is "Urmahlullu," and the swarm-shifter is "Totally Awesome."
 * In fact, D&D ended up wielding this trope against itself. In the first edition of AD&D, the demons didn't have species names; they were simply "Type III Demon," "Type VI Demon," and so on, in order of increasing power. Balor, Vrock, Marilith, and all those were the names of particular demons, samples (or possibly leaders) of their respective types. In the 2nd edition of the game, the given names had morphed over to be applied as species names of the entire Type, so all Type VI Demons were now called Balors, etc., and the "Type ___" designations went by the wayside.
 * Speaking of the Fomorians... As of 4th Edition each Fomor has a cursed Evil Eye that gives them a magical power, but also a painful curse. This was originally a quality of only Balor, but it was too cool a concept not to apply to the whole race.
 * Then there are kobolds. The name originally referred to a type of elf or brownie from Germanic folklore, usually found in a house, on a ship, or in a mine. It was applied to a race of small, dog-like, savage, cowardly Mooks. Then 3rd Edition came along and turned them reptilian, with possibly-true delusions of draconic relations. Then 3.5 and 4th Edition went and made those relations unequivocally real...
 * Deities and Demigods sourcebook turns Sif, goddess of beauty, wealth, and the harvest into Weak but Skilled Action Girl.
 * And It Got Worse. When she appears in TV Tropes, people dismiss Weak but Skilled part and turn her into Hot Chick With a Sword wielding BFS for sometime.
 * She's been like that at Marvel for decades now.
 * Don't forget that it depicts Odin and Apollo as Chaotic Good. Or that it gives Hercules and Thor high Wisdom scores. Or that Hephaestus has a base speed twice as high as a human's.
 * Thor is a wise god(read the Alviss myth),he just prefers not to think much.
 * D&D is also responsible for re-perpetuating Hearn's confusion of the mujina with the noppera-bō.
 * An early Deities and Demigods features Lakota mythology. Suffice it to say, it is full of errors, many dealing with Character Alignment.
 * Scion has a deliberate example. In Judeo-Christian tradition, cherubim are the second-highest rank of angels. When Thoth used angelic ranks to classify the Hands of Aten (which locked their power levels), however, he used "cherubim" for the lowest rank. The reason? Ever since Raphael, humans have associated "cherub" with winged babies (which themselves are derived from the Greek Erotes), and so the idea has more resonance than "cherubim" as kick-ass angel warrior, trapping the Hands thus named in a weakened state.
 * White Wolf's World of Darkness gamelines, especially the Old World of Darkness, fell into this fairly often. Rule of Cool combined with Capital Letters Are Magic meant a lot of concepts in the setting were assigned names from real world cultures or mythologies, but often in a manner tangentially-related at best. (New World of Darkness writers are more aware of this and generally use real-world myths and legends more appropriately.)
 * The vampire clan of warrior-philosophers turned rebel-anarchists are the Brujah, derived from the Spanish word for "witch". While somewhat applicable, Brujah vampires have the most physically-based set of Disciplines (vampire powers); most other clans have far more overt mystical powers (e.g., the Tremere, the clan of vampire wizards, can actually throw fireballs).
 * Gilgul is a concept of reincarnation in Jewish Kabbalism, but in the Mage: The Ascension it refers to the most severe punishment among Awakened: the removal of a mage's reincarnated Avatar. It's almost like referring to extinguishing a flame as "The Ignition".
 * A few relating to the Tzimisce vampire clan of East European vampire sorcerers and Body Horror makers:
 * Vozhd is an old Slavonic word meaning "leader", but refers to giant, barn-sized Body Horror monstrosities the Tzimisce create by merging several dozen people or animals together.
 * Bogatyri was a term for a group of medieval Russian folk heroes, but in the Old World of Darkness refer to a race of blonde giants who served the Tzimisce.
 * Szlachta is a Polish word referring to a historic class of nobility, but refers to ghouls fleshcrafted by the Tzimisce into pure killing machines.
 * In Pathfinder, the Nuckelavee is portrayed accurately by the artists, but the fluff describes it as "a manifestation of natures' rage against all who despoil its beauty. The mythological Nuckelavee (and the one in Dungeons&Dragons 2E) is best summed up as a textbook Omnicidal Maniac.

Theater

 * Played with in The Rainmaker, where Starbuck tells Lizzie the story of Melisande, wife of King Hamlet, who was "the fella who sailed around the ocean and brought back the Golden Fleece." Lizzie is quite aware that Starbuck is making up things as he goes, like the Con Man he is.

Video Games

 * Valkyrie Profile, with Norse mythology.
 * To give a few examples: the game claims Ragnarok will be between the Aesir and the Vanir (the original has the Aesir against the Jotuns), Surt was in frost-encased Jotunheim (when Surt was a fire giant), and makes Frey and Freya into Aesir (they're Vanir). Oh, and Odin has both eyes.
 * The Heroes of Might and Magic games. All of them. The Dungeons and Dragons examples above also qualify here.
 * In Heroes of Might and Magic, Nagas are portrayed as the Dungeons and Dragons monster, Mariliths. In fact, Nagas and Garudas are presented as Anthropomorphic monsters often. Garudas have actually been brought back to their origins because this ties better with the possibility that they might be Ancient Astronauts.
 * The third game also has "Gorgons" that are giant metallic bulls, just like in D&D.
 * In Final Fantasy, Shiva is a goddess of ice and snow and not the eight-armed male Hindu god of destruction. However, this mythtake is explainable: "Shiva" is a pun on the phonetically similar "Shiver" (ice, snow, shiver -- get it?).
 * Revenant Wings plays around with this however in that there are 3 Shiva Summons. Shiva, Shivar, and Shivan. (Shiva, Darling Shiva, and Baby Shiva in the Japanese version) Shivar is male. (And Stated to be Shiva's Lover, while Shivan, again female, is her child)
 * Several Final Fantasies also mess with Celtic mythology for a bit, including summons such as Cú Chulainn and Máel Dúin. This gets somehwhat weird when it turns out Máel Dúin (or Maduin, or Madeen, depending on the translator) is actually important to the plot in FFVI and FFIX. (It gets even weirder when the only instance of the halfway correct translation of the character's name is a recurring random enemy called "Maelduin," who is a blind fish).
 * Then there's Odin and his steed Sleipnir, the latter of which keeps losing or gaining limbs with each interpretation. Odin himself always has both of his eyes, he has all of a sudden grown horns, and he is never found wielding his spear Gungnir, but rather the instant-kill sword Zantetsuken.
 * At least he does use his spear in Final Fantasy IX.
 * In most of his appearances, his summon does a die roll and on success it uses Zantetsuken ("Iron-Cutting Sword"), killing everything on the screen, and on failure uses Gungnir, which hits one random enemy for a fair amount of damage. Zantetsuken ("Iron-Cutting Sword") is a reference to Gram, given to Sigurd, broken, and when it was later reforged, it split the anvil in half.
 * In Final Fantasy VII at least, he only uses the spear against enemies immune to instant death, there's no die roll involved.
 * Final Fantasy VIII has the Guardian Force Quetzalcoatl (actually "Quezacotl" since there was only room for 9 letters), a bird-like Energy Being that shoots off lightning at foes. It was named after the Mesoamerican god whose name means "Feathered Serpent" and was the patron god of wisdom, knowledge, and the morning star.
 * In Final Fantasy XI Garuda is shown as another female deity when all research points to Garuda being male.
 * In Final Fantasy VII, a creature that is clearly a chimera is labeled as a harpy.
 * Probably more of a case of Blind Idiot Translation; earlier FF games are full of errors and oddities, Final Fantasy VII being no exception.
 * Castlevania falls into this a few times, although the worst example by far is Zephyr, a time-controlling boss whose namesake was a Greek wind god (the boss itself is a Shout Out to Dio Brando of ~Jojo's Bizarre Adventure~.
 * God of War does this with Greek mythology, generally making it Darker and Edgier while excising some of the Squick. But, like the TV Hercules example above, it generally hits on the established personalities of the deities.
 * God of War makes an all-too common mistake modern adaptations of Greek myths often make (mainly due to Values Dissonance): depicting the Greek pantheon as ruthless tyrants who oppress and abuse humanity. The truth is that Greek myths were lighthearted, reflecting the general disposition of the people who invented them. The Darker and Edgier elements were first conceived in the dark ages.
 * Actually it's somewhat justified in the ending of the final game where.
 * In Too Human, the Jormungandr is a type of massive war machine created by Ymir, of which only one survives to the time of the game. This is particularly jarring, as prior to this, the game gets a surprising amount of Norse mythology right, and most of the divergences were necessary to the altered setting, or to the story they wanted to tell.
 * The final boss of Breath of Fire 1 is Tyr, the antithesis to the Dragon clan... an evil she-demon, with dragon like powers... Tyr, however, was the Norse god of single combat, victory, and heroic glory. He also had his hand bitten off by Fenrir when they tricked the wolf into allowing himself to be chained. This may have been an attempted Woolseyism: her Japanese name (Myria) doesn't seem to be a reference to anything.
 * In World of Warcraft, there's a male boss named "Skadi the Ruthless" in Utgarde Pinnacle. Skadi was the Norse goddess of winter and the hunt.
 * There is actually a male Skadi in Nordic myth; they're just very, very obscure. The Wrath character could have been named for them.
 * Wrath Of The Lich King is full of Nordic mythology counterparts, but they generally get it right. Freya (fertility) as a guardian of nature, Loken is a trickster, and so on.
 * WoW also uses a large amount of monsters inspired by D&D, which in turn are often named after various mythological beaings but have very little resemblance with the orginal stories.
 * Devil May Cry. Beowulf, the hero of the Geats in the old English poem, is actually a dog-demon thing that becomes gauntlets and greaves that glow with light in this series. Geryon, the monster from Greek mythology said to be a giant with human heads, and then later described in the Divine Comedy as a winged beast with the tail of a scorpion but the face of a man, is really a horse-drawn carriage.
 * It's been suggested this is a case of the names being swapped through mistranslation: Beowulf shares a few characteristics with the Geryon described in Divine Comedy (he has a small scorpion-like tail), and Geryon is described as being a steed to noble heroes, possibly the Beowulf from the poem.
 * On the other hand, the original game hits close to accurate with Alastor, a sword found impaled into a statue of the Judge of Death: in demonology, Alastor is the name given to the supreme arbiter of the court of Hell. Or, alternately, Hell's chief Executioner.
 * But that itself is an example of Sadly Mythtaken, which is essentially what theological demonetization is about: taking figures from other religions and turning them into demons. Alastor was originally another name for Zeus, which actually sort of makes sense when you think about the fact that Alastor uses lightning as its power. Perhaps they simply combined different aspects of the name into one artifact?
 * Also, Beowulf's name and design really make no sense at all when you discover where his likeness came from. His original inspiration was almost certainly Pazuzu, a Babylonian demon of disease, who literally looks exactly like Beowulf. Scorpion tail? Check. Two pairs of wings? Check. Claws on the feet and hands? Check. The face of a dog? Check. Yet despite all of this, they name him Beowulf, and call him a demon of light.
 * It's interesting with the weapon Ifrit. The weapon gives you control over fire, in addition to increasing your physical strength. Ifrit were known to be very extremely physically strong, and were considered to be demons, but the fire doesn't really fit unless it was a reference to One Thousand and One Nights, where an Ifrit turns itself into fire when confronting a woman, only to be reduced to ashes as a result. Fridge Brilliance sets in when you realize that it was attempting to inflict the same fate on Dante by possessing him, but since he is, well, Dante, he's able to resist it, and control it himself.
 * Naming a succubus Nevan really doesn't make sense at all.
 * Shin Megami Tensei, pretty much in every single one of its numerous incarnations, does this to some extent. However, they're generally excused for their creative license for the sheer amount they get right, especially given the prevalence of this trope. As the massive bibliographies for the games included in some of the Japanese-only companion books clearly indicate, this is not so much a case of Did Not Do the Research as "Did the research, but decided something else would be cooler." Rather disappointingly, though, especially with its traditionally major role in the franchise, Cerberus remains some sort of lion-wolf with only one head in all but three games, due to its portrayal in the original Digital Devil Saga novels and anime from which the video games took off.
 * As an example of minor deviancies, Metatron is adorned with crosses despite not being in Christian canon.
 * Darksiders: Wrath of War can top any of the above for bizarre portrayal of Tiamat -- at least the "dragon" bit has some basis from misreadings of the Enuma Elish and confusion with Lotan. In Darksiders, Tiamat is a giant bat monster.
 * That's only the tip of the iceberg as far as Darksiders is concerned. For a game that is obstentially based off of The Book of Revelation, it bears very little resemblance to it.
 * The Battle of Olympus isn't as bad as some examples on this page (apart from the necessary change of having Orpheus fight monsters that were killed by other heroes in the actual myths, and placing some creatures and characters in the wrong locations), but still has a few clangers. Gaia is depicted as a sexless-looking, hostile golem, rather than the goddess of the Earth. On a smaller scale, Orpheus' love interest is renamed Helene (Eurydice who?), the Hydra has only one head, Prometheus is guarded by the Nemean Lion rather than savaged by an eagle, and Circe is depicted as an old crone instead of The Vamp. Hades is the Big Bad, but that's somewhat justified by his kidnapping of Helene being modelled on that of Persephone in the myth.
 * Golden Sun doesn't even bother with accuracy, as many of the summon names were pretty obviously assigned based on what sounded cool. Possibly justified -- it's emphatically not set in our world, and it may be some figures of their world just so happen to have the same name as ours, despite widely different roles.
 * Boreas, minor Greek god of the north wind, is a giant snow-cone machine in the Golden Sun universe. That is all.
 * Until Dark Dawn, in which he became a giant, literal Iron Horse. Wait, what?
 * Only thing they got right about Boreas is that it is the wind the brings winter, fitting the ice theme.
 * Ramses is a ridiculous giant head with even more ridiculous floating fists.
 * Perhaps the most hilarious example occurs with the summon Neptune (derived from the Roman name for the god of the sea, Neptunus). At certain point in Golden Sun: The Lost Age, you fight a boss named Poseidon, which is the same entity only now under its Greek name. You can technically have the summon attack itself.
 * And then there's Moloch, the Canaanite god of Biblical fame, whose man-made idol with a fire in its stomach was apparently offered babies by its worshippers. In Golden Sun: The Lost Age, it's a giant yeti on four legs that exhales a blizzard at you. The Phoenicians would be proud.
 * Coatlicue, the devouring Aztec goddess with snakes for head and clothing, a statue of whom was allegedly excavated by archaeologists who were so disgusted by it that they immediately buried it again, is a Moe Moe Magical Girl who pours Water of Life to heal your party. What.
 * In Mortal Kombat Deadly Alliance, That One Boss Moloch is not a Canaanite god who eats babies, but rather someone who gets to be controlled by Quan Chi and Shang Tsung.
 * Rygar: The Legendary Adventure. It's very obvious that They Just Didn't Care about accuracy, and the game doesn't suffer for it.
 * Kid Icarus. The queen of the underworld is Medusa, Pluton is a common enemy that steals your weapons, Pandora is a giant soap bubble and goddess of calamity and deceit, and Tanatos is a snake that lives in Medusa's hair.

Web Comics

 * In Jet Dream, Athena appears before Harmony to deliver cryptic clues in the fashion of the ghost of J.E.B. Stuart in DC Comics' The Haunted Tank feature. And also to show Harmony new outfits designed by her readers. The supposed writer of Jet Dream identifies Athena not as the Greek goddess of wisdom and warfare, but as a "ghost-girl warrior of olden times."
 * Lampshaded and averted in Spinnerette, when Heather asks her roomate Sahira (who is hindu) why she hasn't likened her to a Hindu goddesses (since she has six arms), Sahira laughs it off and tells her she only bears the most superficial resemblance to a Hindu Goddess, and it would be like saying she looks like Jesus because she grew a beard.

 * Erotic works in the furry fandom sometimes use part-animal gods as sex symbols, regardless of how much sense it would make (although Zeus was famous for shape shifting and then having sex, so this isn't anything new). Anubis: Dark Desires, an erotic comic book anthology, is a prime example. Except, weirdly enough, apart from the erotic aspect, those stories remain fairly true to the mythology.
 * Cleolinda Jones pokes fun at the examples from the Clash of the Titans remake in her Movies in Fifteen Minutes review of it.

ZEUS: Well, technically, our parents were the titans, but your hellrobes don't go too well with my sparkle armor, so maybe that counts."

 * An episode of Tutenstein has Set trap Ra for Apep -- he'd never actually do this, as Set and Apep are mortal enemies and Set has the role of fighting Apep off during Ra's journey through the underworld during the night. (This is sometimes believed to be The Artifact of an earlier role of Set as a positive chaotic figure, opposed to Apep's negative chaotic aspect -- others argue that it's just a mythological instance of Summon Bigger Fish) The show actually lampshades this, however.
 * Mummies Alive did this with Egyptian mythology in so many ways: Egyptians believing in reincarnation, Ancient Egyptian deities behaving more like rogue mystic entities behaving losely like their mythological namesakes (when Anubis, god of the dead, is portrayed as a moronic entity with a dog motif, you know it's bad).
 * When Anubis is portrayed as god of the dead, or god of death, you also know it was bad. That role belonged to Osiris, Anubis was a very minor god of embalment.
 * Pandora's Box in Danny Phantom. For one thing, it turned Pandora into a Badass supernatural being who guards the Box from being opened. In the actual myth, Pandora is the first woman in the world, and she opens the Box because she can't resist the Schmuck Bait.
 * Gargoyles portrayal of most mythic beings, for example Sleipnir having four legs instead of eight. However Gargoyles, like Stargate SG-1, does not claim to represent the myths, but rather the "real" events that evolved into the myths, so this is mostly deliberate. The various gods and such were clearly presented as being related to The Fair Folk of European folklore, in keeping with the show's world-spanning Crossover Cosmology. And not everything is different from the myths: for example, Anubis is quite neutral and emphatic about his nonpartisan role, not evil as in many modern stories. Also, the series' co-creator has explained that the error involving Sleipnir's legs was due to the animation company being unable to animate an eight-legged horse, and presenting him as a four-legged one was better than not having him at all, or just using crappy animation. He stated he would've greatly preferred an eight-legged horse, but had no choice. So, he hand waves as best he can in his mind: like all the other Third Race, the horse is also a shapeshifter.
 * Kim Possible repeats the usual error in making Anubis a demonic figure of menace instead of a sedate guide.
