-> ''"And no wonder, for Satan himself masquerades as an angel of light."''
-->-- '''[[Literature/BookOfCorinthians 2 Corinthians 11:14]]''', ''Literature/TheBible''

When creators want to emphasize the similarity of traits between the [[TropesOfTheDivine forces of the divine]] and the [[InfernalTropes forces of the infernal]], several strategies are used. This trope is about the strategy of similar appearance. Mortal characters encountering both the divine person and the infernal person must rely on subtle clues instead of obvious markers.

In many works of fiction, angels and demons are depicted with obvious markers. Like the two are distinct "races", and often polar opposites. Divine creatures (including good gods) are often {{Winged Humanoid}}s that glow with AngelicBeauty, while Infernal creatures (and evil gods) are {{Big Red Devil}}s with horns, cloven feet, and nasty big pointy teeth. You'd never mistake one for the other, or even think they have much in common. But this trope is for when you ''can'' confuse them. When the two are very similar, and easily mistaken for each other.

If there are any distinctions in appearance at all, they are likely to be subtle. Perhaps GoodWingsEvilWings are involved, with the two groups looking otherwise identical. Or differences in costume while ActingForTwo, where the same actor is used to portray both a Christian God/angel and Satan/demon. That specific technique is most likely [[TropeCodifier codified]] by Creator/GeorgeBurns in ''[[Film/OhGod Oh, God! You Devil]]''. The similarity of appearance is OlderThanFeudalism: The story (or, more precisely, relatively late interpretation) of the [[Literature/TheBible Old Testament]] is that Lucifer ({{Satan}}) himself was the most powerful of the Heavenly Host, before deciding to turn away from his God. He can still appear as [[LightIsNotGood an angel of light]] because he ''is'' one, not because he's disguised. In other words, the difference between angels and demons is the same as between a good human and an evil one.

This trope can be used to complement other similarities. The creator may be trying to show the two groups are similar or GodIsEvil. It can also be used to explain why a normally good person is willing to make a DealWithTheDevil, instead of turning it down out of principle.

Beware BeautyEqualsGoodness: just because an infernal creature can ''[[ShapeShifting choose]]'' to have AngelicBeauty doesn't mean they are angelic. Compare LightIsNotGood, just because a character looks good, doesn't mean they actually are. Compare FaceOfAnAngelMindOfADemon, where a person with an evil mind has a beautiful and innocent face. Compare FallenAngel, where an angel becomes an advocate of evil, and AscendedDemon, where a demon becomes an advocate of good. See also OurDemonsAreDifferent and OurAngelsAreDifferent.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Manga/ChainsawMan'':
** The setting has [[DevilButNoGod only has devils, not angels]] and they're usually quite bizarre and ugly. However, the Angel Devil (i.e. the devil that embodies the [[AbsurdPhobia fear of angels]]) looks like a [[AngelicBeauty beautiful]], [[OtherworldlyAndSexuallyAmbiguous androgynous]] human with [[WingedHumanoid wings]] and a HolyHalo. BeautyEqualsGoodness is for the most part in effect, as he's at worst apathetic about humanity instead of hostile. That said, his TouchOfDeath [[BadPowersGoodPeople makes him dangerous even to his allies]].
** The Control Devil has a less explicit but still pervasive [[MythicalMotifs angelic motif]], specifically [[SatanicArchetype that of Satan as a]] FallenAngel. They look like an [[BeautyIsBad eerily beautiful]] human, command minions [[ReligiousAndMythologicalThemeNaming named after types of angels]], and after recovering from a head injury briefly had an UnusualHalo made of ''brain matter''.
* ''Franchise/{{Devilman}}'' features the character of Satan as a glowingly beautiful hermaphrodite with twelve golden wings. However, in this setting Satan is ''uniquely'' a literal FallenAngel, while the demons are a completely separate species that Satan alone is aligned with.
* ''Anime/DevilMayCryTheAnimatedSeries'': The VillainOfTheWeek in "Rolling Thunder" is a demon with white, glowing skin, [[RedEyesTakeWarning red eyes]], a blue toga and feathery wings. For bonus points, he disguised himself as [[SinisterMinister a priest]] before revealing himself to the heroes.
* ''Anime/DigimonFrontier'' has an {{expy}} of Devilman's Satan in Lucemon, who is also a beautiful childlike angel with twelve white wings. His second form is a bishonen, handsome man with half his wings now stained black, resembling bat wings. While his highest form is outwardly a monstrous dragon, his core is an AngelicAbomination: a gigantic fetus-like worm with golden wings.
[[/folder]]

[[folder:Art]]
* ''Art/TheFallenAngel'': Lucifer, our resident [[TroubledButCute fallen angel, is depicted as handsomely muscular]] as Creator/AlexandreCabanel paints non-corrupted angels in his other works. However, when limiting analysis strictly to the painting's elements, then it's an {{inver|ted}}sion -- the good angels in the background are poorly detailed enough for it to be impossible to call them beautiful.
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/{{Lucifer}}''. In this series (a spinoff of ''ComicBook/TheSandman1989''), Lucifer is depicted as a handsome man with golden wings.
* {{Inverted|Trope}} in the ''ComicBook/New52'' version of ''ComicBook/ResurrectionMan'', where the angels that Mitch runs into sometimes look (and act) a hell of a lot like demons.
* ''ComicBook/TheSandman1989'' has Lucifer, Be'elzebub, and Azazel, the DemonLordsAndArchdevils of Hell. Each of them are depicted with a different appearance, making this trope played straight and averted. Lucifer looks like his angelic biblical appearance, while Azazel appears made of shadows, eyes, and teeth, and Be'elzebub is a giant bug.
* ''ComicBook/{{Hellblazer}}'' occasionally has demons looking like angels to trick mortals.
* ''Franchise/{{Batman}}'': The ''Gothic'' storyline, written by Creator/GrantMorrison, has the serial killer/black magician Mr. Whisper encounter a young, beautful homeless girl who bears a startling similarity to the nun he'd once raped and then burnt at the stake as a horrific sacrifice when he'd been a corrupt monk in the 16th century. The climax of the story reveals that the girl is Satan himself, [[DraggedOffToHell come to claim his soul at last]].
[[/folder]]

[[folder:Films -- Live-Action]]
* Near the end of ''Film/TheDevilsAdvocate'', [[spoiler: the Devil is briefly seen as the Angel Lucifer]].
* In ''[[Film/OhGod Oh, God! You Devil]]'', Creator/GeorgeBurns plays [[ActingForTwo both God and the Devil]]. They look the same, although the Devil prefers to dress all in red.
[[/folder]]

[[folder:Literature]]
* In ''Literature/CosmicChristmas'', Satan assumes his angelic (Lucifer) form in an attempt to fool Archangel Gabriel into thinking he never rebelled and the whole uprising was just a test by him and God to test Gabriel's faith. It's implied only he can do this, as a previous demon Gabriel encounters who pretends to be trying to return to the angels remains in a demonic form.
* ''Literature/TheDresdenFiles'' varies this. On the one hand, it has Chaunzaggaroth a.k.a. 'Chauncy', an oversized monstrous, chitinous looking monster with an Oxford accent, spectacles, and an AffablyEvil demeanour, and most of the Denarians, Fallen Angels with mortal hosts who usually transform said hosts permanently (or just in combat) into monstrous looking creatures. On the other, it has other Denarians, like Lasciel - or rather, her shadow in Harry's mind, 'Lash' - who routinely appears to Harry in the guise of an attractive young woman, sometimes even more or less literally angelic. She even explicitly lampshades this, pointing out that she used to be a resident of Heaven and can still put on the look - before somewhat drily asking if she should add the wings and the harp.
* ''Literature/GoodOmens''. The narration notes that there's "not that much difference" in appearance between angels and demons, except the demons are better-groomed. One of the running themes of the book is that angels and demons aren't so different.
* [[BigBad Lucifer-Satan]] in ''Literature/LeftBehind'' appears in [[VoluntaryShapeshifting many guises]], but his true form is a wonderful angel of light. His appearance is so awe-inspiringly beautiful that even [[IncorruptiblePurePureness a saintly old Christian scholar]] who has spent his whole life studying the Bible immediately wants to worship him when he sees him in a vision, and has to be brought back to his senses by a good angel.
* In ''Literature/ParadiseLost'', Satan is able to disguise himself as a cherub to fool Uriel into allowing him to travel to Earth.
* In Robert Louis Stevenson's short story "Markheim" the protagonist meets a supernatural creature and assumes it is the devil. The creature offers to help him with the crime Markheim is committing -apparently a classic temptation from the devil. [[spoiler: Markheim resists the temptation and calmly admits his crime and waits for the police, knowing full well he will hang for it. Unseen to Markheim the creature undergoes a strange transformation and is triumphantly happy with Markheim's decision.]] The ending suggests it might actually have been the exact opposite.
* ''Literature/TheSilmarillion'': Sauron's "angelic" guise as Annatar, Lord of Gifts, belied his demonic nature and enabled him to manipulate the Elves and Númenoreans. However, he ends up with ShapeshifterModeLock due to being caught in the destruction of Númenor, meaning he is unable to ''return'' to his fair form after that.
* The demons in the ''Literature/BookOfSwords'' make themselves appear this way to Vilkata, as they provide his vision. He isn't fooled for a moment, but given [[EvilOverlord his character]], it doesn't stop him from making use of their services.
* Occurs in surprising crossover with FaceOfAnAngelMindOfADemon in ''Literature/MyBestFriendsExorcism''. While Gretchen is still trying to fight off [[spoiler:the demon from Hell that is trying to possess her]], everyone is horrified by how ugly she is (as she refuses to shower or sleep). The minute she gives in, Gretchen regains her perfect "angelic" appearance and then some.
* In ''Literature/TheMonk'', when Satan is first summoned by Matilda, he appears as an AngelicBeauty whose only demonic attributes are the black color of his wings and a subtle moodiness to his expression, which is probably done to trick Ambrosio into thinking that he's easy to bargain with. When Ambrosio gives into temptation at the end of the novel and summons him to make a DealWithTheDevil, he appears as a more traditional ugly horned devil instead.
* ''Literature/TheScrewtapeLetters'': This one gets discussed; from the way Screwtape talks about it, apparently it's a fairly typical "parade-ground exercise" for a demon to make themselves appear as an angel of light.
* There's one scene in ''Rise of the Fallen'', the second book of ''Literature/WarsOfTheRealm'', where [[{{Satan}} Apollyon]] confronts Validus to try to [[FallenAngel sway him to his side]]. When he first appears, he is glowing white like an angel instead of the usual black of a demon. This of course is in direct reference to 2 Corinthians 11:14 above.
[[/folder]]

[[folder:Live-Action TV]]
* The series ''Series/{{Brimstone}}'' follows Detective Ezekiel Stone, as he is sent on a mission to hunt down 113 damned souls that escaped from Hell. Satan visits at least OnceAnEpisode, played by Creator/JohnGlover and wearing a good-looking business suit. When an ''angel'' appears later on, Creator/JohnGlover is dressed in a very worn-out shirt and pants outfit. Ezekiel first mistakes him for Satan, wondering why the new outfit.
* In the ''Series/StarTrekDeepSpaceNine'' episode [[Recap/StarTrekDeepSpaceNineS07E17Penumbra "Penumbra"]] the Pah-Wraiths (Prophets exiled from their home in the Wormhole) appear to Kai Winn Adami in a vision, claiming to be the Prophets.
* ''Series/{{Supernatural}}'': Both angels and demons require host bodies to manifest, making their appearance similar in that sense. But higher tier demons are also capable of calling upon [[LightIsNotGood holy white light]] (like angels!), one of the most powerful spells of the series.
* An example of ActingForTwo was found in an episode of ''Series/TouchedByAnAngel'', where an evil twin of Monica (one of the regular angels "touching" human lives) showed up.
[[/folder]]

[[folder:Music]]
* ''Music/{{Kamelot}}''. In the song "Descent of the Archangel", Mephisto (named for a demon in Literature/TheBible) appears to Ariel in his full angelic glory, offering Ariel a bargain for his soul. {{Lampshade|Hanging}}d by the demon:
-->''"Speak, my friend, you look suprised --\\
I thought you knew I'd come disguised\\
On angel wings, in [[LightIsGood white]]..."''
[[/folder]]

[[folder:Tabletop Games]]
* In ''TabletopGame/DemonTheFallen'', the low-Torment demons are virtually indistinguishable from non-Fallen angels, allowing the former to pass for the latter to the mortals.
* In ''TabletopGame/DemonTheDescent'', the Unchained take their appearances from the mission on which they Fell and adapt them from there.
* Demons in TabletopGame/{{Exalted}} can appear like practically anything, restricted in the most nominal sense by the themes associated with their patron Yozi. Many demons settle into the gruesome shapes they have been given by their broken patrons, but many demons with faces, especially those of the 2nd and 3rd Circles, appear positively photogenic. In a Creation where a god, an elemental, a fey prince, and the greatest of Exalted can all appear almost the same, the demons who can use their more wholesome shapes to their advantage will do so.
* ''TabletopGame/ShadowOfTheDemonLord'''s "angels" turn out to be outright a type of [[TheLegionsOfHell dev]][[TheFairFolk ils]] in the service of [[SatanicArchetype Diabolus]] whose role is to foster HolierThanThou and KnightTemplar attitudes in strongly religious people as a way to tempt and corrupt them into perdition. They cloak their true horrible appearance in {{glamour}} to appear as beautiful, shining, winged people.
[[/folder]]

[[folder:Video Games]]
* As pictured on the trope page, Lucifer in the ''Franchise/ShinMegamiTensei'' franchise can appear as his original self: the seraphic "Helel". Whether it's his true form or not is really dependent on the game: sometimes it is, sometimes it's a disguise, sometimes Helel is treated as a separate demon entirely, or not even a demon at all.
* One of the most basic powers that a FallenAngel has in ''VideoGame/NexusClash'' is the ability to appear as a good angel. This lasts until someone notices the trail of bodies...or tries to heal them, since this is a setting where NoCureForEvil is very much in effect.
* In ''Franchise/TheElderScrolls'', this is both played straight and subverted in different instances for the [[OurGodsAreDifferent Daedric Princes]], who are (very loosely) the "devils" to the Aedric "angels". The Princes are technically divine beings AboveGoodAndEvil who operate on their own scales of BlueAndOrangeMorality depending on the spheres over which they govern. They can take any form they choose, from "divine" to outright {{Eldritch Abomination}}s, though most [[AFormYouAreComfortableWith stick to a humanoid form when dealing with mortals]]. The best straight example is Meridia, who is associated with LifeEnergy, [[LightIsNotgood Light]], and [[ProudBeauty Beauty]]. She has a FallenAngel backstory and is typically depicted as a beautiful woman, sometimes with [[GoodWingsEvilWings angel-like wings]]. She is typically considered one of the "good" Daedra, though that's more due to her [[EvilVsEvil opposing the undead and some of the nastier Princes]] rather than her actually being benevolent, as she's a ruthless, self-righteous {{Narcissist}} [[TautologicalTemplar who regards herself as the ultimate good and anyone who opposes or disobeys her as evil]].
* The ''VideoGame/DevilMayCry'' series quite enjoys this trope, tying in with DevilButNoGod:
** ''VideoGame/DevilMayCry1 1'': Moments prior to the final clash with Dante, [[BigBad Mundus]] initially appears in a massive, cathedral-like chamber, and his stone visage is carved to resemble a handsome, three-eyed angel. As the battle rages on and his statuesque form is ripped apart, his true grotesque demonic features are revealed underneath.
** ''VideoGame/DevilMayCry2'': Argosax is the FinalBoss of Dante's campaign. When initially confronted by Dante, Argosax is presented as [[FusionDance a macabre amalgamation of]] [[BodyofBodies several bosses]], resulting in a grotesque lump of flesh with countless demons' faces and limbs gruesomely merged into each other. After Dante defeats it in that state, Argosax evolves into his [[OneWingedAngel Despair Embodied form]], which resembles an angelic creature of fire and light. Unlike the aforementioned Mundus whose angelic form is an outer shell to disguise his grotesque appearance, Argosax's angelic visage is his true form.
** ''VideoGame/DevilMayCry3DantesAwakening'': "The Fallen" are late-game enemies that appear to be winged angels, but receiving enough damage destroys their protective wings and reveals hideous [[BellyMouth demonic faces in their bellies]].
** ''VideoGame/DevilMayCry4'': Several [[CorruptChurch Order of the Sword]] members underwent experiments combining human and demon DNA. Despite this, their demonic forms are either covered up by their templar outfits, strongly resemble angels, or are fused with [[AnimatedArmor hollow angelic armors]]. Even Agnus, who assumes the form of a humanoid beetle, is still bright white and gold and has a glowing halo. Sanctus is a subversion as he retains a holy visage after the Ascension Ceremony, but his [[spoiler:Diabolica form in the finale gives him demonic features and a corrupted appearance]].
** ''VideoGame/DevilMayCry5'': In mission 3, Nero faces the boss Artemis, a demon which appears to be a cross between a mermaid and a six-winged angel.
** It isn't simply the demons that are affected by this trope - certain areas of Hell seen in the first and third games resemble distorted versions of Heaven and the locations are filled with very deceptive light.
* Pride from ''VideoGame/DarksidersIII'' is one of the [[Characters/DarksidersSevenDeadlySins Seven Deadly Sins]], a group of demons so powerful and dangerous that the Charred Council had them imprisoned shortly after {{God}} created them to protect the rest of the universe from their influence. With that said, her design from her almost-human physiology, her blue angelic wings, and her purple and gold armor would have you believe her to be an angel. The only giveaways would be her black cape, her broken-looking halo and [[spoiler:her mangled face underneath her mask]].
* ''VideoGame/HeroesOfTheSeasons'': Matria is the demoness of illusions and artificial light, and takes the appearance of the goddess Vyena: a beautiful woman with angel wings. Her campaigns' battlefields also look like the inside of a holy temple, but is filled with demons and false angels. In Armageddon mode, [[spoiler:she transforms into a grotesque monster and the battlefield transforms into a hellish location]].
* Hell in ''VideoGame/SagaFrontier'' looks like FluffyCloudHeaven, and its demons in turn look like winged cherubs. Until you touch one and the fight starts, at which point the illusion drops.
* ''VideoGame/DoomEternal'':
** Blood Maykrs introduced in the ''Ancient Gods'' DLC are Maykr Angels who have been corrupted by the demons. They still retain most of their angelic Maykr qualities right down to their [[GoldColoredSuperiority golden wings]].
** The Maykr race as a whole could count as an example of this. Although they are framed as angelic beings, with their home dimension of Urdak compared to Heaven, the plot not only reveals them to be [[spoiler: far more despicable than the demons they claim to fight against,]] but also reveals that [[spoiler:the Maykrs and the demonkind were both created by the Dark Lord Davoth]]. Tellingly, the two main Maykr characters the Doom Slayer interacts with, the Khan Maykr and Samur, [[spoiler: both start looking increasingly demonic]] as the plot goes on.
* ''VideoGame/{{Ultrakill}}'' has the Idols; [[LivingStatue statue-like demons]] that resemble busts of [[PietaPlagiarism the Virgin Mary cradling baby Jesus]] and wield holy magic to [[SupportPartyMember buff their allies]] by making them invincible. Their [[MonsterCompendium lore entry]] justifies this trope, [[spoiler:as their holy form is intentionally carved by their [[TheFerryman Ferrymen caretakers]], who gave them their new form out of gratitude for [[ArchangelGabriel Gabriel's]] mercy, and compassion for their HappilyAdopted demons. The Idols even absorbed holy magic from their caretakers' divine robes and use it to protect others out of love, essentially making them [[AscendedDemon holy demons]].]]

[[folder:Web Video]]
* ''WebVideo/MandelaCatalogue'': Having stolen the identity of the ArchangelGabriel, {{Satan}} uses his face and likeness to deceive various biblical figures and prophets in the Biblical Times sections. [[SubvertedTrope Subverted]] in the Modern Times, where he stopped giving a care about his disguise a long time ago and deforms it into monstruous proportions.
