* ''Godyssey'': A 1990s crossover featuring Rob Liefeld's Glory and Avengelyne (which is a co-creation with Kathy Christian). Avengelyne has a nightmare about the Greek gods mocks a crucified Jesus, and later she joins forces with Glory to stop a plot by Zeus and the Olympian deities to dethrone the Abrahamic faith and rule over Earth.

** The most prominent Marvel god characters are the Norse god [[ComicBook/TheMightyThor Thor]] and Greek god Hercules, both of whom have served on the Avengers. Many other pantheons exist as well, alongside "new" godlike beings such as the Eternals, the Celestials, the Elders of the Universe, Eternity, and others. A storyline in ''ComicBook/TheIncredibleHercules'' featured Herc leading the "God Squad," a task force of Greek, Inuit, Egyptian, Japanese, and Aztec gods that teams up to defend the Earth from encroachment by alien Skrull deities.

* One theory for Zeus' legendary [[ReallyGetsAround horniness]] is that the dalliances of multiple gods were ascribed to him (i.e. one group's myth of a tryst between the local thunder god and fertility goddess later became attributed to Zeus and his sister Demeter).

** ''Literature/WarOfTheDreaming'' blends, among others, Celtic, Greek, Christian, Norse and Cthulian mythi.

* ''Literature/OmniscientReadersViewpoint'': A major part of the setting is that all mythological characters exist as beings known as Constellations, with more well-known Constellations being stronger. Cliques exist (called Nebulas) of constellations from the same mythologies, though unaffiliated constellations can join any nebula if an invitation is extended.

* When Creator/AlanMoore was writing ''ComicBook/{{Supreme}}, ComicBook/{{Youngblood}}'' and ''ComicBook/{{Glory}}'' for Creator/RobLiefeld's Extreme Studios, he invented a system of magic that was based on the Kaballistic Tree of Life and could incorporate all religious systems, from Judeo-Christian to Greek, Norse and Egyptian, to whatever EldritchAbomination the writers wanted to create for the story. Although he was never able to use this system in Liefeld's titles, he later incorporated this system in his own title ''ComicBook/{{Promethea}}''.

When taken to the extreme end of the SlidingScaleOfIdealismVersusCynicism it may result in a Cosmology where local deities are weak and irrelevant and {{Eldritch Abomination}}s and [[SealedEvilInACan other ancient nasties]] can and do casually traipse over any local deities' shrines and followers. Even in more optimistic portrayals, one has to wonder at the fairness of a universe that allows {{Comicbook/Galactus}}, {{ComicBook/Darkseid}}, [[Anime/TengenToppaGurrenLagann Anti-Spirals]], and [[Film/TheMummyTrilogy Imhotep]] to exist.

* ''Literature/TheDresdenFiles'' ''loves'' this trope. The Judaeo-Christian God exists--in fact, Harry's ally Michael even has a sword powered by a nail from the Cross. The gods of all other pantheons are mostly inactive but still exist and the [[FairFolk fae]] play a major role in the series. The existence of chi and karma has been acknowledged. Outsiders---Lovecraftian horrors from outside reality--exist.

** The Norse gods from the ''Film/{{Thor}}'' movies, though the setting [[ClarkesThirdLaw treats them as powerful aliens]] rather than true gods.

* ''VideoGame/{{Dislyte}}'': Gods from Greek, Egyptian, Norse, and Chinese mythologies appear in the game through the Espers that are hosting their power. The Ritual Miracle bosses are based off monsters from three of these mythologies (Apep and Fafnir), or in Kronos' case, a [[Myth/ClassicalMythology Titan]]. There are also NPC enemies based on other mythical monsters such as succubuses, harpies, and elves.

* In Celtic Mythology, there are multiple references to the Classical world that imply the Celts knew about the Greek and Roman gods, and in some ways implemented them into their own mythology. The ''fir bog'', for example, were said to have been enslaved by Greece before liberating themselves. Also there's some versions of The Children of Tuireann, where minor gods Brian, Iuchar and Iucharba go on a quest to fulfill a blood payment, includes obtaining a bushel of magical gold apples. In some versions they're specifically the apples of the Hesperides, the same as the ones from the [[Myth/ClassicalMythology Heracles myth]], meaning there's Irish gods going Film/OceansEleven on the Olympian gods. And one story about Fionn Mac Cumhaill involves him facing off with a Greek dragon that had heard Fionn was a legendary dragon slayer and wanted to test his might.

* ''Fanfic/InfinityTrainSeekerOfCrocus'': The Infinity Train has denizens that would eventually become gods to many mythos. These denizens, called Numinae, come from numerous mythos like Greek (Zeus, Aphrodite) to Egyptian (Anubis, Wepwawet) to Celtic (Lugh) and even Aztec (Quetzalcoatl).

* In Celtic Mythology, there are multiple references to the Classical world that imply the Celta knew about the Greek and Roman gods, and in some ways implemented them into their own mythology. The ''fir bog'', for example, were said to be descendants of the Scythians (a Bronze Age culture near Turkey), and the Tuath De Danann (the gods of Olympus) were believed by some versions to have originated from Greece, alongside the Olympians.

* One theory for Zeus' legendary [[AnythingThatMoves horniness]] is that the dalliances of multiple gods were ascribed to him (i.e. one group's myth of a tryst between the local thunder god and fertility goddess later became attributed to Zeus and his sister Demeter).

* ''Webcomic/{{Housepets}}'': Kitsune (Myth/JapaneseMythology) [=DMs=] for a dragon and a gryphon, the latter of whom is exes with Cerberus (Myth/ClassicalMythology)... all of whom hail from Heaven (''UsefulNotes/{{Christianity}}''), where God and the Seraphim are mentioned offhandedly.

* ''Webcomic/{{Housepets}}'': Kitsune (Myth/JapaneseMythology) [=DMs=] for a dragon and a gryphon, the latter of whom is exes with Cerberus (Myth/ClassicalMythology)... all of whom hail from Heaven (''UsefulNotes/Christianity''), where God and the Seraphim are mentioned offhandedly.

* Christianity is true in ''Literature/TheChroniclesOfNarnia'' with Aslan being a new incarnation of Jesus but there's a mention in ''Literature/TheLionTheWitchAndTheWardrobe'' of the Roman god Bacchus and Silenus (a companion if his Greek counterpart) coming to dance with nymphs and fauns.

** The {{Sourcebook}} ''Astral Realms'' for ''TabletopGame/MageTheAwakening'' offers a way to reconcile the existence of different pantheons: every god ever believed in exists, but only in the Temenos (the collective human unconscious) and [[GodsNeedPrayerBadly only have as much power as human regard affords them]]. Thus, a god like Anubis is
much weaker than when he had a kingdom of believers, but still holds power as a cultural symbol. They may have great insight, but only into human matters, lacking any understanding of greater cosmic issues. It's pointed out that ''they'' still believe they are gods, and will not look kindly on any attempt to inform them of their true nature.

* The original game lines in the ''TabletopGame/OldWorldOfDarkness'' all have creation myths specific to the supernatural monster they talked about (werewolves, mages, vampires, fairies, mummies, wraiths, demons) which are at times hard to reconcile if not mutually exclusive. Some are specifically Judeo-Christian, others are pagan or have cosmologies unrelated to either. In some cases they have world views and game mechanics that say all ''other'' supernatural creatures should not exist, or that they ("they" usually being "mages") can do ''anything''... except cure vampirism or lycanthropy.
** It should be noted that Mages can cure vampirism... but it's not a good idea. The Paradox backlash from that would, in all likelihood, kill the Mage stone dead. As for lycanthropy, what's to cure? Werewolves are not sick, they've always been werewolves.
** Mage having ClapYourHandsIfYouBelieve as its key principle goes a long way though and combined with some alternate realities link the various game lines fairly well... except the vampires who are sometimes called Cainites and thoroughly linked with Literature/TheBible for their BackStory to being literally cursed with God. Albeit even that is dismissible as superstition and most "facts" in the World of Darkness were presented from a specific and unobjective point of view.
** The ''TabletopGame/NewWorldOfDarkness'' is even more inconsistent, the werewolf and mage backstories being particularly extreme in their incompatibility. Therefore, it cheerfully (as cheerfully as the [=WoD=] gets, anyway) ignores this fact. They even {{lampshade|Hanging}} the problem in the ''Changeling'' book, which contains an "Arcadia" which is a truly nasty place; the discussion of this mentions that no one knows whether it's the same "Arcadia" that Acanthus mages use to get their power. Mostly it waves this away by presenting these as mythologies which may well not be perfectly true.
*** It turns out, in the end, that the werewolf and mage backstories aren't referring to the same event (the assumption of which caused the seeming incompatibility). The mage backstory [[CosmicRetcon happened, but never took place in this version of reality]], while the werewolf backstory took place sometime around the Neolithic.
** It is however subverted in ''TabletopGame/MageTheAwakening'' (specifically the {{Sourcebook}} ''Astral Realms'') which has it that while every god ever believed in exists, they only do so in the Temenos (the collective human unconscious) and [[GodsNeedPrayerBadly only have as much power as human regard affords them]]. Thus, a god like Anubis is powerful, though not nearly as powerful as he was, because even if he is not believed in, he is still a relevant cultural symbol. They also possess insights only into human matters (albeit to a great extent) lacking any understanding of greater cosmic issues. It's pointed out that ''they'' still believe they are gods, and will not look kindly on any attempt to inform them of their true nature.
** The storyline stuff in each of the gamebooks and sourcebooks should be considered [[UnreliableNarrator untrustworthy]] as every book in the series seems to be strongly based on the viewpoints of the group that it is about. Which is why references to the same group in two different sourcebooks can be completely contradictory.
** Though it's not ''technically'' a White Wolf game, the fangame TabletopGame/GeniusTheTransgression also adds yet ANOTHER flavour to the mix, with [[ScienceRelatedMemeticDisorder geniuses]] being more than capable of faking deities, and having [[MultipleChoicePast several, mutually contradictory]] beings of power, both [[TimeTravel past and future]]. Also, on a more mundane scale, they have a conspiracy that overlaps and contradicts a conspiracy from TabletopGame/MageTheAwakening, with both groups having once controlled much of the world. It simply says that the two groups ignore each other, and that it is ''curious''.

* ''Manga/SaintYoungMen'', which stars Jesus and Buddha as roommates in Japan while they take a break from their divine duties. One of the chapters has them participating in a Shinto festival, where Buddha worries that they'll be laughing stocks in Heaven if the god of the Shinto Shrine they're carrying finds out that they're there.

* ''LightNovel/HighSchoolDXD'' has a lot of mythologies existing in this story, ''Literature/ArsGoetia'' being the most prominent example. Myth/NorseMythology, Myth/HinduMythology, Myth/GreekMythology, it's all here though apparently there's also one more mythology that ''even the other gods of said mythology don't know about.'' The name of said mythology? [[spoiler: There is a breast god in this series.]]

* Being X from ''LightNovel/SagaOfTanyaTheEvil'' is replaced with a council of gods from different religions in the manga.
* Discussed in ''Literature/{{Gate}}'' where the gods of a fantasy world with only one pantheon are fascinated that Earth has multiple gods for the same purpose. Hardy the underworld goddess falls in love with the idea of the Greek goddess, Aphrodite and makes Itami promise to bring her to Earth so they can meet. Itami near craps himself because he has no idea if Earth's gods even exist.
* ''Manga/AyakashiTriangle'': Despite always being referred to by a Japanese word, [[OurSpiritsAreDifferent ayakashi]] exist all over the world. Since many are {{tulpa}} [[ClapYourHandsIfYouBelieve shaped by human belief]], they correspond to their native mythology. One supporting character is Snegurocha, the snow maiden of Russian folklore, who lived in a picture book that got exported to Japan and ended up a permanent resident there.
-->'''Garaku''': In this global era, it's not surprising to see foreign ayakashi around.
* Some {{Valkyries}} show up in ''Manga/MariaTheVirginWitch'' to take some knights to Valhalla but the ArchangelMichael chases them because the knights are supposed to go to Christian Heaven.
* ''LightNovel/{{Campione}}'': Gods from many different mythologies show up to fight [[TheHero Godou]]; Greek, Roman, Persian, Egyptian. However, many gods could be one and the same entity. Athena, for instance, is also Medusa and Perseus is also [[spoiler:Mithra]].
* ''Manga/MissKobayashisDragonMaid'': Let's see... we have Kanna Kamui (named after an Ainu god) as one of the main characters, [[Myth/AztecMythology Quetzalcoatl]] and [[Myth/NorseMythology Fafnir]] are both secondary characters, and Tohru is mentioned to have a beef with Jesus' dad during the ChristmasEpisode. References to dragons from other mythologies are also made in the passing, like Herensuge from Basque mythology.
* ''Manga/SaintSeiya''. Blatantly obvious in the anime, with the addition of movies and a {{Filler}} arc. To the point where Greek gods, Norse gods, Buddha, and friggin' ''Satan'' fought Seiya and Co. And the universe was created by Big Bang.
* ''Manga/FrankenFran'' has at least two provably existant religions. One? Jesus was real and performed miracles, and the Wandering Jew is a real person. The other? [[spoiler:The Flying Spaghetti Monster is created during the series.]]

* The Franchise/MarvelUniverse has many examples of cosmologies coexisting. As with other decades-old comics universes, the precise details can vary DependingOnTheWriter:
** The most prominent Marvel god characters are the Norse god [[ComicBook/TheMightyThor Thor]] and Greek god Hercules, both of whom have served on the Avengers. Many other pantheons exist as well, alongside "new" godlike beings such as the Eternals, the Celestials, the Elders of the Universe, Eternity, and others. A storyline in ''ComicBook/TheIncredibleHercules'' featured Herc leading the "God Squad," a task force of Greek, Inuit, Egyptian, Japanese, and Aztec gods that teams up to defend the Earth from encroachment by alien Skrull deities.
*** One in-universe explanation is that the Norse, Greek, Egyptian, Olympian, Japanese, Inuit, Aztec etc. gods are all magical, superhuman beings from other worlds and dimensions who were worshipped by different ethnic groups throughout history, and all of the myths surrounding them are, where contradictory, generally misinterpretations or half-truths. They each have distinct origins, but are not above intermingling: Gaea, the Elder Goddess of the Earth, played a role in most or all of these pantheons; aside from being based on the Greek overdeity of the same name, she is the same being as Izanami in the Japanese pantheon, and is the mother of both Thor and Atum-Ra of the Norse and Egyptian pantheons; although, in the Marvel series, both she and Atum-Ra predate all these other groups by billions of years.
*** Another canon explanation (which is simultaneously the ''oldest'' (originally presented in a Thor annual in the 80s) and most ''modern'' (this is what they seem to use at least since JMS's Thor again)) is that strictly defined gods are dreamed up by people, kept alive by memory (forgotten gods are eaten by the Demogorge aspect of Atum), and run on the stories told about them (do not wax or wane with belief) which become retroactively true. There are exceptions, for example Gaea is an [[EldritchAbomination Elder God]] who fit into ''all'' EarthMother myths so the stories just gravitated towards her and didn't become X+1 separate Earth goddesses. If someone thinks this leads to a cosmology ''running'' on circular reasoning and other logical fallacies, that someone is absolutely correct. In mythical Marvel humanity creating the gods being just as true as any TopGod's claim that they created humanity [[MindScrew makes perfect sense]].
** A henotheistic aspect of Marvel cosmology is the ultimate Omniscient God-with-a-capital-G, called "One Above All." The ComicBook/FantasticFour met him in one story, in which he turns out to be... Creator/JackKirby!!! (Or perhaps Kirby was simply AFormYouAreComfortableWith.) Other stories have implied that the "One Above All" is a manifestation of Creator/MarvelComics itself.
*** The One Above All is a justifiable use of AuthorAvatar, showing up as whoever is writing the story. It has been Creator/JackKirby, Creator/StanLee, and others over the years. Literally whoever is writing the story for the comic.
** ComicBook/{{Galactus}} is said to change his appearance based on whoever sees him. To humans, he resembles a giant human. To other aliens, he resembles a member of their race.
** One Comicbook/GhostRider story established that there is a Spirit of Vengeance for each religion and nationality. One of the other Spirits says that the afterlife you go to depends on your belief.
*** This was established long before that story; each pantheon in Marvel has a Death God, most of whom fill out an EverybodyHatesHades-version of the god they are based on and are evil (or at least, AntiVillain) gods who own a portion of the dimension formerly known as Hell, which shattered into numerous other dimensions billions of years ago to become the Splinter Realms- the other owners of such dimensions are DemonLordsAndArchdevils, and all owners gain strength and can expand their realm by the number of souls they possess. The specific rights they have to a given soul are laid out by a contract each Death God and Skyfather (the more benevolent heads of each pantheon) has with the AnthropomorphicPersonification of Death herself, and generally means that if you follow a specific religion, that determines which heaven or hell you go to (Skyfathers generally get the "good" souls according to the morals of their faith; for instance, a good follower of the Norse religion goes to Odin in Valhalla, a bad or neutral one to Hela in Hel). Atheists and irreligious people, however, are judged purely on moral worth- bad guys get stuck with the demons, while good ones go to Heaven (everyone in between is...ambiguous). There are more specific rules for each- for instance, a Christian might still find himself sent to Hela just because he happened to be in Asgard when he died, and there are ghosts and reincarnation and magic and other stuff going on. There are also dimensions ruled by malevolent demonic entities like Dormammu who rule both life ''and'' afterlife and make both as hellish as possible, so keep them off of your "places to visit" list.
** In the ''Comicbook/BlackPanther'' mythos the people of Wakanda venerate both their ancestors and a pantheon of mish-mashed deities from all over Africa; the Black Panther themselves draw their power from Bast, an Egyptian goddess, while Man-Ape is associated with Ghekre, a West African god, for instance. Bast's sister, Sekhmet also has a minor cult in Wakanda. Recently, it was revealed that Bast was part of the Wakanda Pantheon, made up of Egyptian deities:Thot and Ptah and other places in Africa: Kokou (Benin) and Mujaji (South Africa), in addition, there was another cult to a Gorilla deity in the tribe that would be known as Jabari, Ngi (Cameroons). In the [[Film/BlackPanther2018 movie]] this is up-graded with the Jabari worshiping Hanuman, from ''Hindu'' mythology. In the comics, Bast and Sekhmet are rival. These gods are various identified as either Ennead (an Egyptian term) or Orisha (from Myth/YorubaMythology).

* In the ''ComicBook/{{Necrophim}}'' prologue chapter, [[{{Satan}} Lucifer]] sends Uriel to kill Jotunheim, king of the frost giants of Myth/NorseMythology, [[UriahGambit hoping he will die]] in the attempt.
