A lot of contemporary horror fiction uses a strange blend of Christian and [[CosmicHorrorStory Lovecraftian]] mythology. [[OurAngelsAreDifferent Angels]] are good, [[LightIsNotGood usually]], [[GoodIsNotNice but not necessarily nice]]; [[OurDemonsAreDifferent Devils]] are bad, [[DarkIsNotEvil usually]], [[EvilIsCool but often more fun]]; and {{Eldritch Abomination}}s from Beyond just want to [[OmnicidalManiac destroy it all]], or even worse, twist everything into something wholly alien that {{squick}}s out ''[[EvenEvilHasStandards both]]'' [[EveryoneHasStandards of the]] [[EnemyMine aforementioned]] [[EvilVersusOblivion parties.]]

From a story perspective, it makes sense. You see it a lot in stories where GodAndSatanAreBothJerks. The angels serve as foils for the hero, allowing him to show off his rule-breaking attitude. The devils prove the hero's toughness and cleverness by [[TheWorfEffect giving him someone to beat]]. And the outsiders serve as the villains of the story. Also may be a consequence of an AllMythsAreTrue system, with angels, devils, {{Eldritch Abomination}}s, TheFairFolk and Literature/{{the three Billy Goats Gruff}} all fighting with or over the protagonists. Alternatively, you may have a situation of the {{Eldritch Abomination}}s and either of the other two being on the ''[[OurAngelsAreDifferent same]] [[OurDemonsAreDifferent side]]'', vying against the third and whatever's left of humanity in the wake of the subsequent Armageddon.

From a theological perspective, it's a bit muddled. (Oftentimes you can end up with situations where the angels and demons ''are'' squid. Those go here too.) Can result in TheGoodTheBadAndTheEvil--angels, demons, and {{Eldritch Abomination}}s, respectively. If the angels are rarely seen expect EvilVersusOblivion (devils and squid, respectively). If GodAndSatanAreBothJerks and the squid match the usual reputation, you've got yourself a thoroughly CrapsackWorld. If the setting doesn't limit itself to just the Abrahamic and Lovecraftian pantheons, then you've got a full-fledged FantasyKitchenSink on your hands. The Lovecraftian monstrosities may not actually be squidlike; that's just a stereotype. Of course it could follow a more traditional type of alignment, with the angels being good, the devils being evil, and the squid running on BlueAndOrangeMorality.


[[folder:Anime & Manga]]
* ''Manga/{{Berserk}}'' has a lot of overlap between the three archetypes, but they do exist to some extent. The Four Elemental Kings represent the Angels, the Apostles and the Godhand that create them are the devils, and the most powerful and malevolent spiritual beings like the Sea God are the squid.
** The Battle for Windham ends up as a somewhat muddled case of this. Griffith, who takes on an angelic appearance, leads his army of humans and [[OurDemonsAreDifferent Apostles]] against the now [[AttackOfThe50FootWhatever gigantic]] and nearly mindless EldritchAbomination that was once Ganishka and his "army" of {{Cthul Humanoid}}s.
** An Interesting note is that the God Hand are referred to as Five Angels which makes it the case of God Hand being the Angels, Apostles being the Devils and The Squid can be the spiritual entities as well as Ganishka in the battle of windham
* This features notably in ''Anime/DigimonTamers''' finale, mixing with TheGoodTheBadAndTheEvil. [[spoiler:The three most powerful entities during the climax are Dukemon: Crimson Mode, Beelzebumon: Blast Mode, and the D-Reaper]].
* ''LightNovel/{{Slayers}}'' got it not that clear cut, the dragons are basically the angels: good guys, not very nice and will inflict genocide just as fast to keep "peace"; on the other side are demons who are simply out to destroy everything--or, in the case of [[spoiler:Xellos, Greater Beast,]] and their like, there seem to be some that are just want to be evil but not destroy everything. And then there is [[spoiler:Darkstar Dubranigdu]] from another world just out to end it all, [[spoiler:but more likely for the sake of doing it over without the eternal war between dragons and demons]].

[[folder:Comic Books]]
* In the ''ComicBook/{{Hellboy}}'' cosmology, horned-and-tailed demons exist (and possibly angels as well), but everyone in the upper echelons of all sides is a nightmare from beyond. The biblical seven-headed dragon from the Apocalypse is made up of seven alien creatures in cocoons, while its spawn are either bugs, frogs or cephalopopds.
* IDW Publishing crossover comic series ''Infestation'' has every kind of supernatural creature possible. For instance, in the universe where it begins, ''Comicbook/ZombiesVsRobots'', the Covert Vampire Operations task force is made up of several vampires (field operatives), a zombie (TheSmartGuy), and a demon (an actual horned red-skinned demon... who wears a suit to the office). No actual angels are shown, but a zombie outbreak reveals a strange multi-dimensional HiveMind creature that infects several parallel realities (i.e. franchises) with a technorganic zombie plague using this world's MagiTek. The sequel has another threat in the form of aliens escaped from Area 51 with allied demons living deep underground. After defeating them (and meeting their resident demon's mommy and daddy), they find out that the demons are running away from something else located even deeper. The Old Gods are exactly what you expect. Giant odd-shaped creatures of immense power with tentacles that also proceed to penetrate into other realities/franchises.
* ''Comicbook/{{Lucifer}}'' has shades of this. The main character is a fallen angel, who deals with other fallen angels, all of whom have their own agendas. There are also other demons active in hell who are more basic demonic types. There are various angels of the non-fallen variety who serve God (nominally--it's made clear at times that this God's will or ability to communicate is limited at times). Lucifer earns a letter of passage outside the established order and discovers some other type of thing called a Jin En Mok (we see two) from before the established order. They tend to look like what(who)ever they last ate, with the implication that their real form (if any) is not pretty.
* ''Comicbook/{{Spawn}}'' offers a variety: there are angels and demons (both of whom [[GodAndSatanAreBothJerks serve morally questionable entities]]), and independent abominations, often creatures that did not take part in the Heaven\Hell battles.
* Comes up in ''ComicBook/RequiemChevalierVampire''. There are two factions of powerful entities that exist beyond the world of Resurrection and seek control over it: the Masters of the Infinite, which seem to be [[EldritchAbomination rather eldritch]] and thus fill the role of the squid, and the Lords of Limbo, which are the devils. Angels also exist, though they have pretty much no influence on Resurrection whatsoever and the only one ever seen is captured and used as a WMD.

[[folder:Fan Works]]

* In the ''Fanfic/PonyPOVSeries'', the Alicorns and Draconequi are the 'angels' side (as despite representing Order and Chaos respectively, they're both actively benevolent, with even Havoc, who rules [[{{Main/Hell}} Tartarus]], being more of its prison warden than the devil), while Discord and Morning Star are the 'demons' side (with [[FallenAngel Fallen Alicorns and Draconequi]] being called Devils and Demons respectively). The Pain Monsters sealed deep within Tartarus also fit, being very demon-like. The 'Squids' are the [[EldritchAbomination Outer Concepts]], a third family of gods born from their [[TopGod Elder]], Azerhorse. They're so completely alien that they're not only different from the Alicorns and Draconequi in every sense, but can't even relate to ''each other''. They collectively represent the Fear of the Unknown and exist to keep mortals from being too reckless in their progress. There's also a ''fourth'' variety of deity who are a part of none of the above families, which includes Mother Deer ([[spoiler:actually the Tree of Harmony, which is born of both order AND chaos]]), Queen Tiamat, and King Bahamut.


* Creator/JRRTolkien's '[[Literature/TheLordOfTheRings verse]] has angels (the Valar) and devils (Morgoth and Sauron), the latter of whom are classic 'fallen angels' in their origins having started out as members of the angelic order. Dotted through Tolkien's creation, though, are weird primordial creatures like Ungoliant, a colossal dark spider-entity of pure blight and destruction, or the Nameless Things at earth's roots mentioned by Gandalf during the trip through Moria. At least one actual squid (the Watcher in the Water) is confirmed.[[note]]Technically--except in the live-action movie, the Watcher never appears in full, and may well not be a singular entity, but its tentacles ''definitely'' evoke a cephalopod.[[/note]]
** Middle-Earth also, intriguingly, contains something of an inverse 'squid' in the shape of the being known to hobbits as Tom Bombadil: an ancient elemental force with no specific aims or objectives that simply loves existence, he seems not to be an angelic figure and takes no part in the battles between conventional good and evil, in the sure knowledge that before and after all of it he will be there still doing what he does. His only intervention is against Old Man Willow, another primordial entity that loosely fits under the 'squid' category, making Bombadil seem more akin to a 'good' counterbalance to mindless oblivion than anything. Nobody knows what exactly he is; some early readers thought he was an incarnation of Eru Ilúvatar (i.e. {{God}}), but Tolkien {{Jossed}} that theory. However, he gave no alternative category for Tom, so readers started to guess that he was a Maia (lower-order deity) who "went native".
* Literature/{{Discworld}} has a pantheon that's made up of mythological expies, and in one novel shows the equivalent of Hell (although in several, Death metes out punishment to wrongdoers). On the "squid" side of things, there are the creatures from the "Dungeon Dimensions" (a reference to ''TabletopGame/DungeonsAndDragons'', described occasionally as resembling the offspring of a squid and a bicycle) as well as the Auditors, who due to BlueAndOrangeMorality are basically Omnicidal Lawful.
** The Things crave the light and shape of "our" reality, and attempt to break through whenever [[MagicIsAMonsterMagnet some really powerful magic weakens the fabric between worlds]]--it's been said that if they ever succeeded, the effect would be that of an ocean trying to warm itself around a candle. They fit the "not evil so much as alien" bit mentioned above, as Rincewind realises they'd kill us without giving us "the dignity of hatred".
** The Auditors make sure the fundamental laws of the universe continue to work, but find life-forms of any kind infuriatingly unpredictable. When they're not looking for a way to wipe out people entirely, they're trying to make us less erratic by [[{{Discworld/Hogfather}} eliminating belief]].
** The very first Discworld novel ''Discworld/TheColourOfMagic'' speaks of Bel-Shamharoth, a very squidy Lovecraftian horror described as "the opposite side of a coin where good and evil are the same side." Things like it were apparently fairly common in an earlier age when there was more magic around. They were all things from the aforementioned dimensions that leaked through during the eras of reckless magic use that managed to anchor themselves into a static image in reality.
* ''Literature/MerkabahRider'' initially involves the battle between Heaven and Hell. In later stories, the Cthulhu Mythos intrudes as a third faction.
* In ''Literature/PerdidoStreetStation'', some of the characters [[spoiler:try making a pact with some [[TheLegionsOfHell Legions of Hell]] to help them fight an escaped abomination. It's a major OhCrap moment when they realize not even the devil wants to go near it, and they have to go find ''another abomination'']].
* ''Literature/{{Kraken}}'', by the same author, also invokes this. Although in this case [[OurAngelsAreDifferent the angel is literally a squid]]. The occult world revolves around various cults, which believe in and so create their own angels and devils, and one of them happens to worship krakens as their gods. (Giant squids are their miniscule offspring.)
* ''Literature/SandmanSlim''
* ''Literature/TheDresdenFiles'' actually ''does'' feature angels, devils, {{Eldritch Abomination}}s called Outsiders, TheFairFolk, and the Billy Goats Gruff.[[note]]They're part of the Fairy Summer Court, since you asked.[[/note]] [[Creator/JimButcher The author]] took the time to specify the difference between ordinary demons and {{Fallen Angel}}s, and why demon-summoning is allowed under the Laws of Magic but summoning Outsiders is most certainly ''not''.
** Demon-summoning (as in calling up demons for information or services) is technically allowed, as is bargaining to get, for example, a squad of mercenary pixies for the day in exchange for a dozen pizzas. Enthralling (as in crushing free will) is one of the few laws that protects nonhuman entities, mostly because people who enslave demons do not make them volunteer at the soup kitchen; and dominating the will of another being is considered a [[EvilIsNotAToy form of black magic]] that makes [[JumpingOffTheSlipperySlope further black magic easier]]. But even trying to ''learn'' about the things beyond the Outer Gates is an instant death penalty, because while it's theoretically possible to employ demons for benign means (as Harry had done a couple times), no good can ''ever'' come of tangling with Outsiders.
** This also appears in ''Cold Days'' in the form of [[spoiler:the reason for the Faerie Courts' existence; the Winter Court holds back the Outsiders, while the Summer Court keeps the Winter Court from screwing with mortals too much]].
* Creator/SimonRGreen's ''Literature/{{Nightside}}'' has this going on in droves, but with an emphasis on the "Squid" more than the other two. Book 2 has a blend of all three, and devils make more appearances than angels, but in a place where {{Eldritch Abomination}}s walk the streets... Yeah.
* ''Literature/{{Johannes Cabal|TheNecromancer}}'' shows devils in the first book and Lovecraftian types in the third. The heavenly hosts have not yet been shown, but Cabal claims to know of them, and is not impressed.
* Open to interpretation and dissent, but possibly a case in the CanonDiscontinuity ''Literature/TheChroniclesOfAmber'' prequels. The canon series gave us the ''Evil'' Courts of Chaos and the ''Good'' City of Amber (for varying degrees of good and evil), while the prequel series started to introduce the Feynim, an alien-looking and inscrutable third force that seemed to be trying to manipulate the protagonists.
* ''Literature/{{Divine Blood|Novels}}'' has Gods and Demons and then it has Nameless Things. So far, the only Nameless Thing shown is the one released at Grimsvotn and that was beaten by Lilitu alone. However, she was still recovering from injuries related to that encounter months later and Urd berated the Queen of the Demons for allowing the situation to happen. The matter is further confused by the fact that Lilitu, a powerful and high ranked Demoness, is also a devoutly practicing Christian.
* In ''Literature/TheBelgariad'', you had the agents of Light (Belgarath, Beldin, Belgarion, etc.), the agents of Dark (Torak, Zandramas, etc.), and the agents of ''Chaos''--the demons.
* This is actually as old as ''Literature/ParadiseLost'', which features angels and devils as well as two {{Eldritch Abomination}}s called Chaos and Night.
* ''Literature/GoodOmens'' turns this trope on its head a bit. The heavenly host and the armies of hell play the squids, working in tandem but not together to bring about the apocalypse, with a lot of talk about an "ineffable" plan that none of the humans and not even the angels or demons can understand. A third faction consisting of a single angel, a single demon, and a few humans (including a witch, a witch hunter, and the AntiChrist) is trying to prevent the apocalypse. This third faction alternates between playing the role of the demons and the angels, thanks to having nominal members of the other two factions, and various humans trying to uphold or subvert the order around them. Ultimately subverted when the rebel angel and demon realize after it's all over that there's only one player, Big G himself, and the whole thing went JustAsPlanned.

[[folder:Live Action TV]]
* The Franchise/{{Buffyverse}} is an interesting case. There are humanoid demons and angels but in the highest order, they're both squid.
* Possibly the case in ''Franchise/StarTrek''. On the side of angels, we have the Bajoran Prophets. For devils, we have the Pah-wraiths and Fek'lhr. And for squid, we have weird extradimensional beings like Species 8472, or the soul-sucking Devidians.
** And depending on the day and their mood, the Q can fit into any or all three categories.
* The mythology in ''Series/{{Supernatural}}'' has angels from Heaven, demons from Hell, and Leviathans from Purgatory (which Lovecraft himself attempted to access with a portal). The Angels are hardly paragons of goodness, but the Leviathans are predictably the most evil of all of them. Then there's TheFairFolk, who come from another dimension and seem to be in a different category of supernatural beings.
* The conflict between the Vorlons and Shadows in ''Series/Babylon5'' plays out like this. The Vorlons actually portray themselves as angels (or the nonhuman equivalent) to the younger races and insist on order ''[[WellIntentionedExtremist at any cost]]''. The Shadows are explicitly agents of chaos, seeing conflict and destruction as [[ForYourOwnGood the only way for the younger races to properly evolve]]. The squid [[spoiler:and specifically the Chief Squid, Lorien, turn out to be the ones to end the conflict and get the Vorlons and Shadows off the younger races' backs]].
** More fittingly The Squids would be the Thirdspace Aliens, whom Vorlons bumped into when they built what they percieved to be gates to Heaven. Suffice it to say, it turned out anything but.

* Myth/NorseMythology (as it is recorded, anyways) has two sets of deities, the Aesir and Vanir, and the monstrous Jotunn. The three factions have been at war, though the Aesir and Vanir made peace. The former two were worshiped and considered benevolent, while the later were primordial forces of nature and evil in some cases.

[[folder:Tabletop Games]]
* Possibly the case in ''TabletopGame/DungeonsAndDragons''. Originally there was no concept of good and evil, just order and chaos. The gods were opposed by infinite demons from a place called the Abyss, which wrecked all their works. They created angels to fight the demons for them and some of those angels, while remaining loyal to the concept of order, became as destructive and cruel as the demons they faced, seeing it as necessary to do their jobs. They became the first Devils. So now there were both LawfulEvil devils, who want to take over the universe, and ChaoticEvil demons, who want to destroy it. [[UnreliableNarrator Or so the story goes, anyway]]; [[TheRashomon it's just one of many versions of the creation myth]]...
** There's also the bizarre creatures from [[EldritchLocation the Far Realms]], who have a very Lovecraftian vibe. Celestials (angels, archons, guardinals and eladrin) are pure good, fiends (devils, demons, yugoloths) are pure evil, but the creatures of the far realms are just plain ''alien''. Expect [[CombatTentacles tentacles]] and people [[GoMadFromTheRevelation going mad from encountering them]].
* Definitely the case in D&D 3.5's SpiritualSuccessor, ''TabletopGame/{{Pathfinder}}''. The Angels are represented by the Empyreal Lords (including the goddess Sarenrae) and their attendant [[OurAngelsAreDifferent Celestials]], while The Devil bill is filled by the [[ChaoticEvil Demons]] (and their goddess, [[MotherOfAThousandYoung Lamashtu]]), the [[LawfulEvil Devils]] (and their god, [[{{Satan}} Asmodeus]]), and the [[NeutralEvil Daemons]] (led by the HorsemenOfTheApocalypse), as well as several other less influential/powerful fiendish groups. As for the squid, there's the [[EldritchAbomination Qlippoth]], primordial evil entities that predate all sentient life, full god [[OmnicidalManiac Rovagug]] (who may be an ascended Qlippoth) and various Lovecraftian Entities from the darkness beyond the stars, and Zon-Kuthon, the local godly ''Franchise/{{Hellraiser}}'' ShoutOut, is a toss-up as to whether he's more devil or squid. And just off to the side there's the Eldest who rule over TheFairFolk.
* ''TabletopGame/{{Exalted}}'', being a FantasyKitchenSink, is made of this trope. There's the gods in [[{{Heaven}} Yu-Shan]], the Yozis and demons in [[{{Hell}} Malfeas]], the [[EldritchAbomination Neverborn]] and their [[TheUndead Deathlords]] in TheUnderworld, TheFairFolk, the Alchemical Exalted and [[TheCorruption Void Lords]] in [[EternalEngine Autochthonia]], the [[OurDwarvesAreAllTheSame Mountain Folk]] and [[BeneathTheEarth Darkbrood]], the [[DinosaursAreDragons Dragon Kings]], and pretty much anything else you can imagine, all hankering for a piece of the Creation pie for one reason or another. Interestingly, the Squid part of the equation is the most prevalent, as at least the Neverborn, the Yozis and the Fair Folk are all different takes on the concept.
* ''TabletopGame/NewWorldOfDarkness'' role-playing games have little in the way of angels, but some, like the Qashmallim, are present. Devils (Goetia, creatures of the Inferno) are more of a presence, but not as much as the flavors of Squid (Abyssal Intruders, elder spirits like the Idigam, Cthonians and Kerberoi in the Underworld, even TheFairFolk have strong shades of squid). The Inferno and Abyss do not get along--one wants to corrupt the material world and depends on it to survive, the other wants to destroy reality.
** ''TabletopGame/MageTheAwakening'' more specifically has a hands-off version of Angels and Devils, with the sorta-benevolent Oracles and the tyrannical Exarchs, and some very hands-on Squid in the form of the Abyss.
** ''TabletopGame/DemonTheDescent'' introduces prominent groups of angels and demons, with the angels being agents of the status quo and the demons opposing it.
*** Weirdly, the God Machine that created the clear Angels and Demons is a Squid (well, Techno-Squid) to the rest of the world of darkness, being an esoteric mechanical eldritch horror in contrast to the more traditional World of Darkness fantasy creatures.
* ''TabletopGame/{{GURPS}} Dungeon Fantasy'' does this with the Gods from Heaven, the Demons from Hell and the Elder Things from the Outer Void.
** It also has "nature" as a force, causing some fans to joke that the "alignments" of the game are Good, Evil, Squid and ''Bunny''.
* ''C.J. Carella's TabletopGame/WitchCraft'' RPG has this in full force, and it comes to a head with the sequel game ''Armageddon'' where the Angels and Devils [[EnemyMine have to join the Pagan Gods and other normal supernaturals]] to fight off a colossally powerful EldritchAbomination and its DarkMessiah's ReligionOfEvil.
* ''TabletopGame/LegendOfTheFiveRings'' has [[OrderVersusChaos the Kami on one side, the Oni on the other side]], and then there is the [[PowerOfTheVoid Nothing]]. [[DidYouJustPunchOutCthulhu Which was on the receiving end of an epic butt-kicking in the previous edition]].
** Like everything else in it, this has some basis in Myth/JapaneseMythology: On one side you have the Celestial gods, on the other side you have the Terrestrial gods, and then there is the Amatsu-Mikaboshi, god of evil and the stars.
* ''TabletopGame/{{Nobilis}}'' has two factions of Angels (Heaven and the Light), two factions of Devils (Hell and the Dark), one faction of solipsists who don't care about either (the Wild), and the role of the Squid is played by the [[HumanoidAbomination Excrucians]] and [[EldritchAbomination Actuals]]. Notably, there's a lot of LightIsNotGood and DarkIsNotEvil (their roles are less good vs evil and more about society and the individual), and the Excrucians are frequently AffablyEvil.
* ''TabletopGame/{{Warhammer 40000}}'' ZigZags this trope a bit.
** The [[TheEmpire Imperium of Man]] approaches from the "angel" side with [[CrystalDragonJesus God-Emperor of Man]] and the [[AscendToAHigherPlaneOfExistence Living Saints]] and the [[DarkIsNotEvil Legion of the Damned]]. It's an authoritarian, xenophobic, heavily militarized society which is just short of being outright stated to be a bastardized version of what the Emperor's vision. While they can't be accurately described as either [[LightIsNotGood "good"]] or [[GoodIsNotNice "nice"]], the Imperium is humanity's best hope for continued survival.
** [[GodOfEvil Chaos Gods]] and [[TheHeartless daemons]] are unambiguously the Devils, and sometimes also the Squid.
** The [[OurOrcsAreDifferent Ork]] Gods of [[WarGod Gork and Mork]] are Angels for the [[BloodKnight Greenskins]], but Devils to everybody else.
** The Eldar Pantheon was essentially one of Angels and at least one Devil, but most died when the newest Chaos God was born and attacked them. There were only three survivors: [[GodOfGood Isha]], who was taken as a trophy and eventually captured by a rival Chaos God; [[WarGod Khaine]], who narrowly survived by [[LiterallyShatteredLives breaking into pieces]] and escaping into the material realm; and [[TricksterArchetype Cegorach]], who [[ScrewThisImOuttaHere peaced out]] and fled into another dimension.
** The [[PhysicalGod C'Tan]] with how weird they were, could reasonably serve as Squid until the Necrons, their followers, [[RageAgainstTheHeavens killed or shattered them and sealed away the shards]]. The newly arrived [[BugWar Tyranids]] brought their HiveMind, savagely intelligent and ruthlessly Darwinian and driven only by unending hunger, serves as a new and different Squid.
* ''TabletopGame/{{Rifts}}'', of course, has this in spades, being one of the most gonzo {{Fantasy Kitchen Sink}}s out there, though the angels are usually thin on the ground, and the squid tend to have an outlook almost identical to that of the devils.
* ''TabletopGame/SentinelsOfTheMultiverse'' has a mystic landscape where these factor in. Angels seem to exist: the hero Fanatic is a white-winged woman who deals lots of radiant damage and is devoutly religious, and her arch-enemy Apostate appears to be a fallen angel, [[spoiler:neither of which are actually angels but are instead members of The Host who are emotion spirits. Sort of. Itís confusing and complicated.]]. Demons exist: Gloomweaver is a human sorcerer who became one. As for the Squid, there's the Void, also known as [[Franchise/CthulhuMythos R'lyeh]], the power source for the hero Nightmist and the minor villain Ruin.

[[folder:Video Games]]
* ''VideoGame/WorldOfWarcraft'' similarly plays with this trope. It has Angels in form of the Naaru (who look like giant glowing wind chimes, but are still the good guys), the Burning Legion for the Devils (some of whom match the classic demon descriptions along with some original designs), and the Old Gods and Faceless Ones for the Squid.
** At the dawn of time, only Light (Angels) and Shadow (Squids) existed. The Twisting Nether (Devils) was created as a result of Light and Shadow clashing (along with the physical universe, in a sort of magical Big Bang). However, despite the Angels and Squids being more equal on a cosmic hierarchy, the Squids have had a lot harder time interacting with the physical world, so the Devils end up usually being the primary antagonists and enemy of the Angels. Also, the Devils are only organized to begin with because of a WellIntentionedExtremist FallenAngel who was absolutely horrified to learn of the Squids, and saw the destruction of all life as a preferable alternative to what the Squids have [[ApocalypseHow/ClassZ planned]].
* Downplayed in the ''Franchise/{{Disgaea}}'' series. There are angels, devils, and aliens, but the angels might have faults, the devils might be not so evil, and the aliens aren't quite alien. All of them look very human, and the story usually revolves around a devil protagonist.
* In ''VideoGame/KidIcarusUprising'', the player character, Pit, is the Angel, the Devils are [[spoiler:[[CardCarryingVillain Hades]] and [[KnightTemplar Viridi]]]], and the Squid are [[spoiler:[[StarfishAliens the Aurum]]]].
* ''VideoGame/AdventureQuestWorlds'' has Good, Evil, and Chaos. Interestingly, the forces of Chaos look more like demonic beings with lots of purple colors, and tentacles, while the Shadowscythe are just TheUndead.
* ''VideoGame/FallFromHeaven'' mostly follows the angels and demons part of this trope, but does include the Octopus Overlords, basically directly lifted right from Lovecraft type stories.
* ''VideoGame/OracleOfTao'' has angels and demons as part of the cosmology. The Lovecraftian stuff is also there, but is mainly in odd areas of the game (if you break sequence, or go heavily into bounty hunting). The game has a LovecraftLite feel to war between Heaven/Hell/wherever the squid critters are from.
* ''VideoGame/TheSecretWorld'' certainly has all three, as befits a game where AllMythsAreTrue, with a horror theme as a major component. The main enemies, responsible for the [[TheCorruption Filth]] which influences most events in the game, are lovecraftian "mollusc gods" said to come from some version of deep space. They are called "dreamers", since the filth is actually an idea of theirs made real, which is strong enough to take the form of an oily liquid and corrupt almost everything it touches. In addition, players fight back demonic invasions from a FireAndBrimstoneHell. Angels appear less frequently at various points in the game, including the opening cutscene, and the demonic invasion is led by a {{fallen angel}}.
** You can make a case that the player factions also represent a humanistic echo of this trinity. The Templars have over their course attempted to climb from effective rulers to benevolent rulers and protectors to acting as angels with utter righteousness and commitment to inviolable moral law, though absent the authority of an OmniscientMoralityLicense they're far more obviously fallible than the real thing. The Illuminati were born of light, fell hard and far, and reorganized on a general rejection of morality, but have had done so much bad for so long they're gained vast experience with the self-defeating element of various evil acts - and unlike demons, they aren't locked into ForTheEvulz: they've slowly approached EnlightenedSelfInterest from the "wrong" direction. The Dragons at least reject the idea of moral or immoral values, they fail to reach BlueAndOrangeMorality only because they're still human enough to have a comprehensible, self-worthwhile goal: to understand causality enough to know what about destiny and reality can be changed, how and why. Doing things just to see if they're possible rather than for the results means neither value systems nor self-interest can be used to predict or explain what the Dragons do, even for members of the faction.
* ''VideoGame/{{Diablo}}'' mainly focuses on the Angels and Devils, but some Squid are present in the novels, such as the dreamers, who are stated to come from a dimension beyond both Heaven and Hell, as well as whatever Trag'Oul is (although, he's more of a benevolent squid). And in [[VideoGame/DiabloIII the third game]] there are some squiddy creatures in pandemonium that don't seem to be of angelic or demonic origin, but they don't affect the mortal world because the demons are basically running a monopoly on invading it.
* ''VideoGame/{{RIFT}}'' could be interpreted this way. The Vigil and their Guardians are the Angels, the Defiants are humans but play the Devil's role, and the Dragons and the Planar Invaders are the Squid.
* ''Franchise/TheElderScrolls''
** This is loosely the case with the series' primary deities, [[OurGodsAreDifferent the Aedra, the Daedra, and Sithis]], respectively. The Aedra are the et'Ada ("original spirits") who participated in the creation of Mundus, the mortal plane, and thus sacrificed much of their divine power and very beings to create it. They are the primary deities worshiped by the religion of the [[SaintlyChurch Eight (later Nine) Divines]]. The Daedra are the et'Ada who did not participate, and thus maintain their CompleteImmortality. While technically beings AboveGoodAndEvil who operate on their own scale of BlueAndOrangeMorality defined by the [[AnthropomorphicPersonification spheres over which they govern]], they are generally considered evil, or at least malevolent toward mortals, by most denizens of Mundus. Finally, Sithis is the "[[PowerOfTheVoid great void]]" embodiment of the primordial force of chaos, and is easily the "squid" of the group.
** Within the ranks of the Daedric Princes, this trope is also in play. Some of the more benevolent Princes (such as Azura or Meridia) fit the "angels" part, though GoodIsNotNice can be very much in effect for them. Some of the more malevolent Princes (such as Molag Bal and Mehrunes Dagon) fit the "devils" part, with them trying to [[TheCorrupter corrupt]] or [[OmnicidalManiac destroy]] mortal life. Hermaeus Mora is the "squid", not even bothering with [[AFormYouAreComfortableWith a humanoid form]] like the others, preferring to take shape as an infinite mass of tentacles and eyes.
* VideoGame/FallenLondon has devils walking the street and squid-faced citizens known as the Rubbery Men, although oddly there don't appear to be any angels. The Church does have a large presence in the city though.[[spoiler:The Rubbery Men are just regular aliens. The actual Squid role is played by [[LightIsNotGood the stars themselves.]]]]
* ''VideoGame/{{Dominions}}'' has a variety of celestial and infernal beings (given the variety of myths used, angels and demons might be a tad simplistic)... and the Starfallen R'lyeh, home to the madness-inducing illithid and their ilk. In general, "angels" (which can include things like Hindu divinities and Zoroastrian azatas) are summoned using astral magic, "demons" (including Japanese oni and the nastier sorts of Aztec divinities) are brought into the world with BloodMagic, and "squid" (almost entirely Lovecraftian, ''TabletopGame/DungeonsAndDragons'' derived, or unique to Dominions) require [[YinYangBomb a mixture of blood and astral magics]].
* The world of ''VideoGame/DarkSouls'' has the Lords of Anor Londo as the Angels who strive to preserve world order through underhanded means; the demons of Lost Izalith as the Devils who spread chaos and misery as if they were natural; and the creatures of the Abyss as the Squids who indiscriminately try to plunge whatever they can into the world-destroying Dark. [[spoiler:Unusually both the Devils and the Squids came from the Angels; the demons were spawned by a corrupted Lord and the Abyss was created by a forgotten Lord. Humanity is linked to the Abyss, meaning that [[HumansAreCthulhu humans are technically Squids]].]]
* Demons in ''VideoGame/NexusClash'' are divided into archetypical devils ruled by the iron fist of [[ManipulativeBastard Tlacolotl]] and BodyHorror-based tentacles and gibbering masses of flesh drawn from the incomprehensible body and mind of [[EldritchAbomination Tholaghru]]. The angels' response to both is usually some combination of KillItWithFire and HolyHandGrenade.
* ''VideoGame/{{Darksiders}}'': Angels and Demons share the same existence with a multitude of other races that are collectively known as Abyssal Creatures, that are older than both races and they come in many shapes and sizes though they are mostly {{animalistic| abomination}}. The Chosen from the first game were beings summoned by [[BigBad the Destroyer]] to serve as his generals in the End War and were initially thought to be demons themselves, but its [[RetCon clarified]] in the second game that they don't belong to either race and came from the Abyss rather than Heaven or Hell.
* ''VideoGame/LeagueOfLegends'' essentially has these three. For Angels, there's Kayle (a literal angel from another world) and a variety of divine and semi-divine entities, mostly associated with Mount Targon: Aurelion Sol, Leona, Diana, Zoe, Taric, Pantheon, Soraka, and Bard. For Devils, there are two demons: Evelynn, a succubus, and Tahm Kench, a catfish creature who offers [[DealWithTheDevil certain deals]]; there are also a selection of sinister undead entities, generally from the Shadow Isles, that may also qualify. As for Squid, there's the Void, an EldritchLocation inhabited by horrible monsters.

* ''Literature/WhateleyUniverse'' characters encounter all three. Phase has fought a demon and devils (in that story at least a Lovecraftian thingy), Fey led a team against Lovecraft-tainted Weres, and some of the main characters (like Carmilla) may be evolving ''into'' the squid end of the trope. Some of the secondary characters deal with the angels and devils--Seraphim is... some kind of mutant with access to possibly the Christian heaven, while Merry had to talk to and reject what may have been the actual Devil in order to become a Holy Knight.
* The Wiki/SCPFoundation sometimes deals with entities that are religious in nature, with Biblical entities including what is assumed to be God himself and a crater that leads to hell. Of course, the site is mostly known for Lovecraftian entities that are barely contained.
