->''There's a Mr. B. Al. Zebub here to see you, sir. He says [[CorruptCorporateExecutive he's a big fan of your work]].''
-->-- '''Secretary''', ''Speed Bump''

This is the flip side of [[GodWasMyCopilot finding out you've got a god (or God)]] hanging around incognito. This is [[TheReveal when you find out]] that that slightly strange fellow who's been loitering nearby is... [[{{Satan}} the other one.]]

Maybe the literal Devil has taken a personal interest, or maybe it's just a high-level demon or an Agent of General Badness, whatever the local badness happens to be called. In any case, it's powerful, it's bad, and it's been standing right there next to you all this time. Yikes!

Be very wary of guys named "Lou", "Luke", "Lukas", or "Lucius", particularly if their last name is Siffer or Cypher or [[NamesToRunAwayFromReallyFast something like that.]] Keep an ear open for Milton (author of ParadiseLost) and [[NamesToRunAwayFrom/{{Mor}} Morgenstern]] (German for "morning star"; but [[EveryoneIsJesusInPurgatory be careful with this one]], "morning star" is [[MessianicArchetype also a title for Jesus]].[[note]]''I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.'' (Rev. 22:16)[[/note]]). Also take a careful look at the ones named "Nick", "Scratch", "Deuce", "Thorn" or some variant thereon. In certain cases, don't trust [[HotAsHell women named "Lucy" or "Georgia."]] Apparently the Devil's not very good at choosing aliases, despite having a huge variety to pick from. Or maybe it just shows [[GoodIsDumb his opinion of the hero's intelligence level]]. Or, it could just be ego.

Common in DealWithTheDevil stories. See also SdrawkcabName. Related to MostDefinitelyNotAVillain. If GodIsEvil, Louis Cypher may be a StevenUlyssesPerhero. SubTrope of DevilInDisguise.

If this character isn't at least ''implied'' to be the Devil himself, but just has a demonic sounding name to [[NamesToRunAwayFromReallyFast emphasize their general evilness]], the example should go on [[NamesToRunAwayFrom/DemonsOrAngels this page]].

For those who don't understand the title: [[spoiler:[[ArchangelLucifer Lucifer]]]]

'''This is often a reveal trope, ''so spoilers ahoy!'''''

----
!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Literature/DemonCityShinjuku'', Mephisto is a rather nice guy although when it comes time to face off with the big bad, Mephisto threatens him and says to play fair or he will help the good guys. He never really comes out and says it though but it is heavily implied that he is if not Satan himself much stronger than the supposed bad guy.
* In ''RevolutionaryGirlUtena'', [[spoiler: Akio Ohtori's name is derived from the Japanese term for the Morning Star - which, as he notes, is commonly used to refer to Lucifer. It's appropriate, considering his past as the angelic Dios and his current ManipulativeBastard role. He casually reveals the etymology behind his name to Utena halfway through the series. She still [[DistractedByTheSexy takes a while to catch on]].]]
* The demon "Sebastian Michaelis" of ''BlackButler'' is a quite clever example via GeniusBonus. Sebastian is the stock name for butlers in Japanese tv, but [[http://en.wikipedia.org/wiki/Sebastien_Michaelis Sebastien Michaelis]] was an actual person, a French inquisitor and [[TheWitchHunter witch hunter]] who wrote about supposed instances of demonic possession. Thus, having a demon calling himself that is a similar effect to [[Film/TheDevilsAdvocate having Satan call himself John Milton]].
** It was revealed that Sebastian's name was given to him by Ciel, who [[spoiler: named him after his dog.]]
* Maou Sadao from ''LightNovel/TheDevilIsAPartTimer'' may have the worst alias ever. The given name he chooses, Sadao, is an odd but believable and written 貞夫 (good husband). Unfortunately the characters he chooses for his family name are 真奥 (secret inside) and he pronounces them "Maou" which means devil. The official English translation is Jacob Satan.
[[/folder]]

[[folder:Comic Books]]
* Lew Siffer in [[http://www.chick.com/reading/tracts/0034/0034_01.asp this]] ComicBook/ChickTract, among others.
* [[{{Darkseid}} Boss Dark Side]] from the DCUniverse series ''SevenSoldiers''.
* Lucifer in ''Comicbook/{{Lucifer}}'' makes a slightly better effort than most, going by the name Mr. Lux (Mr. Light, still a reference to Lucifer's Latin meaning of 'light bearer') even though he puts so little effort in otherwise that it seems the only reason no one identifies him is because they're too embarrassed or scared to ask.
** Or too distracted by his resemblance to DavidBowie.
* Mr. L.C.F. Sat in the ''{{Valerian}}'' album, ''In Uncertain Times''. He's sort of an antagonist in the story, but by no means a bad guy, and gets himself a happy ending.
* In ''The Gift,'' bullies pick on a freshman named Lucius Sephar, who has been bound into the form of a ninth-grader as God's punishment. Needless to say it doesn't end well for the bullies.
* When the Antichrist from ''Comicbook/GhostRider'' has to keep low profile, he decided to [[HiddenInPlainSight hide]] [[DevilInPlainSight as]] [[TeensAreMonsters teenage]] CorruptCorporateExecutive under the name Anton Sat'An. Multiple times he has to [[AccidentalMisnaming remind people his last name is not]] {{Satan}}. And when two Ghost Riders, one DemonSlayer, [[AntiAntiChrist Daimon Hellstrom]] and entire army of Angels gets on his back, [[WhatAnIdiot he's suprised they have found him so easily]].
* In ''ComicBook/{{Squee}}!'' the protagonist Todd Casil is invited to the home of the anti-christ, Pepito. Despite the fact that Pepito has a distinctly demonic look and powers his mother did not realize her husband Juan Diablo was in fact Satan in disguise.
* In TheDCU, Lord Satanus adopted the identity of Colin '''Thorn'''ton as part of a plan to to corrupt {{Superman}}.
* Inverted in ''ComicBook/FallOfCthulhu'' with Lucifer, whose chosen name is simply a portmanteau of her first two given names (Luci Jenifer).
* In the ''LegendsOfTheDarkKnight'' story "Gothic", this is alluded to but not actually used. There's a character named Morgenstern, the villain ''did'' make a DealWithTheDevil, and the Devil [[HowUnscientific actually manifests in the story]]. They just happen to be three separate characters.
* Principal Diablo in ''ComicBook/AllGhoulsSchool'' (although Diablo may not be an alias).
* Basically being Satan in green armor, [[TheDCU DC]] villain Neron did this a few times in UnderworldUnleashed.
[[/folder]]

[[folder:Fan Works]]
* FanFic/GoddessRebornChronicle has [[FallenAngel Lucifer]] going around as [[GenderBender Nicky]], a [[TheFakeCutie smarmy]] girl. [[/folder]]

[[folder:Film]]
* The trope title is from a misspelling of the name Louis Cyphre from the movie ''Film/AngelHeart''.
** {{Lampshaded}} by Harry.
-->'''Harry:''' "Louis Cyphre". Lucifer. Even your ''name'' is a dime store joke.
** With another {{lampshade}} piled on by Louis.
-->'''Louis:''' Mephistopheles is ''such'' a mouthful in Manhattan.
* John Milton(Creator/AlPacino) of [[OccultLawFirm Milton, Chadwick & Waters]] from ''Film/TheDevilsAdvocate''. Creator/JohnMilton, ''Literature/ParadiseLost'', get it?
* Some of the creepiest characters created by DavidLynch are heavily implied to be this. This includes [[LostHighway the Mystery Man]], [[TwinPeaks BOB]], possibly [[MulhollandDrive Mr. Roque and the Cowboy]].
* Louise C. Faire (Anjelica Huston's character) from ''SeraphimFalls''.
* Daryl Van Horne in ''TheWitchesOfEastwick''. A horny guy with horns, two for the price of one.
* Nightclub owner George Spiggot in ''Film/{{Bedazzled 1967}}'', though he's fairly open about being the Prince of Darkness.
** Inverted in the remake of ''Film/{{Bedazzled 2000}}''. The Devil reveals herself straight off - but try to figure out which character is actually God.
* ''Highway to Hell''. After the hero's car is damaged while traveling through Hell, he meets a helpful passing mechanic named "Beezle"...short for "Beelzebub".
* Mr. Nick in ''Film/TheImaginariumOfDoctorParnassus''.
* The Dark Hermit in ''Film/TheGreatestStoryEverTold''.
* In the 1984 film ''Crossroads'', the devil is an old black man from Mississippi who calls himself Legba (the name of one of the Voodoo loas), though by the mid-1980s he's changed his name to Mr. Scratch.
* In ''OhGodYouDevil'', Satan visits Bobby Shelton with the name Harry O. Tophet, a reference to [[http://en.wikipedia.org/wiki/Tophet the Canaanite sacrificial city and a euphemism for Hell.]]
* ''Film/TenaciousDInThePickOfDestiny'': [[spoiler: The open mic host]] turns out to be the devil wanting his tooth back. In a deleted scene, [[spoiler: Lee]] has scary black eyes of doom, implying he's possessed or being used as a disguise.
* Dan Aykroyd once said of the long-in-DevelopmentHell third ''Film/{{Ghostbusters}}'' movie would involve the Ghostbusters going to Hell and meeting a fellow named "Lou Sifler".
* "Lucy Fir" from ''666: The Child''.
* [[spoiler:Charlie Meadows]] in ''BartonFink'' is heavily implied to be this.
* Cypher, [[spoiler: the murderous and traitorous human crewmember]] from ''Film/TheMatrix'', says [[spoiler: to Agent Smith on his deal to return to the Matrix in exchange for the capture of Morpheus,]] that "ignorance is bliss." His name also represented a number opposite to Neo: one definition of "Cypher" is "zero," in contrast to Neo, the [[TheChosenOne One]].
* In Polanski's ''Film/TheNinthGate'', the engravings' signature :
--> '''Corso''' : "L...C...F. Who's [[FunWithAcronyms LCF]] ?"
--> '''Ceniza Bro''' : "Think."
* In ''Film/{{Equinox}}'', a demon disguises himself as an unassuming park ranger... He picks the subtle moniker of "Mr. Asmodeus".
[[/folder]]

[[folder:Literature]]
* Mr. Scratch, in Stephen Vincent Benet's "Literature/TheDevilAndDanielWebster". He doesn't make much of an effort to conceal his true identity, however.
* Old Scratch, in Creator/WashingtonIrving's "The Devil and Tom Walker".
* The titular figure in Creator/StephenKing's award-winning short story "The Man in the Black Suit."
** Also George [[MeaningfulName Elvid]] in the 2010 novella "[[Literature/FullDarkNoStars Fair Extension]]."
** Andre Linoge (an anagram for ''Legion'') in ''Literature/StormOfTheCentury''.
** He doesn't have the MeaningfulName, but Randall Flagg from ''Literature/TheStand'' and other King novels fits this trope in every other way.
* In ''TabletopGame/CallOfCthulhu'' stories and games, it is not uncommon for [[EldritchAbomination Nyarlathotep's]] presence to be part of the Reveal, sometimes quickly followed by TotalPartyKill.
** "Neil O'Tip? The guy doesn't look Irish." Lifetime achievement award to Anime/NeonGenesisEvangelion\Lovecraft Fusion Fic [[http://www.thekeep.org/~rpm/eva/coaeg.html "Children of an Elder God"]], by John Biles and RPM.
** Neil Arthur Hoteph, the well dressed black gentleman from Egypt, is also a very popular one.
* Creator/PiersAnthony's ''Literature/IncarnationsOfImmortality'' series has Natasha, "Ah, Satan" [[SdrawkcabName spelled backwards]]. It's also a legitimately common name which originated in Russia as a derivative of Natalya, so it doesn't seem like quite a dead giveaway… Just plain weird, anyway, as it's a female name, and the character is male.
* In the Creator/KatherineKerr novel ''Freezeframes'', the character Nick Harrison is revealed to be the devil. While not as common nowadays as Old Nick, Old Harry is another term for the devil, as used in TheBBC radio comedy ''Old Harry's Game''.
* He's not exactly Satan, but [[spoiler:Low-Key Lyesmith]] from the Creator/NeilGaiman novel ''Literature/AmericanGods'' turns out to be [[spoiler:a Norse god with a suspiciously similar sounding name]]. He's bad news, to say the least. ''Literature/AmericanGods'' also contains a wealthy, "forgettable" god who is essentially the inversion of this trope: even the WordOfGod about him is an [[TheUnreveal unreveal]].
** Similarly, on the RP board "The Sueniverse", Loki takes on the mortal identity of one Lukas Ashton (ash being the species TheWorldTree is). This is something of a convenient coincidence, since he's actually usurping the identity of a human being with the same name. Ironically, this is originally mistaken for a hint that he's a ''vampire''- they're a lot thicker on the ground in that setting than gods, and some of the older ones are immune to the effects of ''ash'' wood that plague the younger vamps.
* ''Literature/GoodOmens'' by Creator/NeilGaiman and Creator/TerryPratchett similarly features the four motorcyclists of the apocalypse adventuring incognito, before they are revealed as the horsemen. War, for instance, was a wartime journalist who (naturally) had a knack for finding conflict wherever she went. Famine, going by the name "Raven Sable," was a diet food mogul.
* In one of Creator/IsaacAsimov's more humorous theological stories, the entity responsible for the LowestCosmicDenominator afterlife following the end of the world turns out to be a fellow named R. E. Mann (Ahriman, the Zoroastrian term for the God of Evil). After God reveals his ongoing {{Plan}} (he never meant to end the world but has been talked into giving conditions in which it ''could'' end in the form of prophecy), R. E. Mann goes to work writing a proposal for a unified world calendar, so that he can produce a day that the whole world will agree is the proper date.
* There is a German story by James Kruss entitled "Timm Thaler", in which the antagonist's name (at least in the Russian translation) is Tretch. [[spoiler: The protagonist sees his name in the mirror in the latter half of the book, it turning out to be an anagram of "Chert", which is Russian for "Demon"]]
** In the original German, he's called Lefuet, which is a good SdrawkcabName if you know German.
** There was a TV adaptation (which didn't have much in common with the book, by the way) where the antagonist was called Baron Lived.
* John Collier's short story "Thus I Refute Beelzy". A condescending, obnoxious father finds that his son's imaginary playmate has another, more diabolical name.
* In a bizarre, but fantastic portrayal, ''Literature/NotWantedOnTheVoyage'' indicates Satan as a seven-foot tall transsexual named Lucy. She's also on the side of good; Noah is evil. It's that kind of book.
* Derek Leech from Creator/KimNewman's stories.
* One interpretation of Joyce Carol Oates's short story "Where Are You Going, Where Have You Been?" is that the antagonist is a representative of Satan. This is supported by his strange name, "Arnold Friend."
** In addition to this, flies are present throughout the story. Flies are often associated with Beelzebub, Belial, and Satan. The car in the story also has the words "Man the Flying Saucers" written on it, which, rearranged, spells "Lying man, he uses craft"
** Plus, there is a sort of offhand line, if I recall correctly, ever so slightly suggesting Arnold Friend (A(r)n Old F(r)iend?) just might have hooves instead of feet.
*** In particular, he's wearing boots and has really bad balance. It's not so much implied, though; he either has hooves or literally no feet, since his boots bend sideways at the ankle at one point.
** He also describes events taking place several blocks away as they're happening, in enough detail that makes it seem unlikely that he's just making it up.
* In ''Literature/FalseMemory'', a Creator/DeanKoontz novel, the evil psychologist is named Mark Ahriman. Not only is his last name identical to the name of the chief figure of evil in Zoroastrianism, but when he travels, he uses aliases that have two things in common: very ordinary first names, and [[CharacterNameAlias last names that are the name of the Devil]]. One example is "Jim Shaitan," Shaitan being one of the names for the Devil in Islam.
* The title character in Dacre's ''Zofloya; or, The Moor''.
* Louis Cypher in William Hjortsberg's ''Falling Angel''. Louis ends up laughing at his own lame pun (to the protagonist's irritation) about solving the "Cypher".
* The butler in the Literature/{{Nightside}} novel ''Hell to Pay'' says his name is Hobbes -- at least, that's how John Taylor hears it at the time. He later realizes that "Hob" is an archaic name for the devil; the butler actually said "my name is Hob's".
* Forced to disguise himself in ''Literature/BillTheGalacticHero'', the seven-inch-tall Chinger named Bgr builds a MobileSuitHuman and calls himself Beager.
* In Alexander Kuprin's story "The Star of Solomon" the devil uses the name "Methodius Isayevich Toffel" i.e. Meph-Is-Topheles.
* Professor Woland, "expert of the occult", from Mikhail Bulgakov's ''Literature/TheMasterAndMargarita''. Woland is a nickname of the devil in German folk legend and one of the many {{Shout Out}}s to Creator/JohannWolfgangVonGoethe's ''Theatre/{{Faust}}'', where Mephistopheles lets on that he sometimes uses this alias.
* In the German pulp series ''Literature/ProfessorZamorra'', using anagrams of or other plays on his real name when disguising himself as a human is explicitly a long-standing personal quirk of the demon lord Asmodis -- who's generally powerful enough to not mind being found out and so probably just does it for his own amusement.
* In "The Devil's Footprints" from ''[[Literature/PointHorror 13 More Tales of Horror]]'', the Devil mixes among a house party in England, though everyone thinks he is simply an ordinary guy in a goat costume.
* "Triumff", by DanAbnett, is about a conspiracy to overthrow the English throne led by SinisterMinister Aleister Jaspers. A minor character hanging around the edges of the book is a humanoid cat, who in the epilogue is revealed to be [[spoiler:the ''real'' Aleister Jaspers, implying the BigBad was an example of this.]]
* ''Literature/PleaseDontTellMyParentsImASupervillain'' gives us Lucyfar, who claims to be the [[{{Satan}} Archangel Lucifer]] herself. In a mild twist, she makes no attempt to hide this.

[[/folder]]

[[folder:Live Action TV]]
* Briefly, Ray Wise's character in ''Series/{{Reaper}}'', although he identifies himself pretty quickly.
* In the sitcom ''HomeboysInOuterSpace'' the Devil appears in one episode under the name of "Mr. Tan". The heroes realize the truth when one of them says "say, Tan..."
* ''TheDrewCareyShow'' took this UpToEleven when Kate's boyfriend "Jack" comes to Drew for a job interview and reveals that "The Devil" is not merely his nickname. ("Does he have a van? I bet the Devil has a really cool van.") At one point he even shows the gang his driver's license (first name The, last name Devil). We learn that he's from Jersey (natch) and his previous job experience includes used car sales, the DMV, the post office... and UNICEF. ("Hey, nobody's all bad!")
* In ''Series/TheTwilightZone'' episode "Dealer's Choice" a group of friends find themselves playing poker with a stranger named "Nick", who keeps getting three sixes in every hand he is dealt...
** Another episode centers around a strange gentleman who goes by the name "Mr. Smith" who appears after the protagonists says he'll do anything to keep his failing newspaper business going. Mr. Smith modifies their typing machine and everything he reports eerily happens shortly ''after'' he writes about it. Then he tells the protagonist he'd like him to sign a contract turning over his soul as payment...
** Yet another episode features an "A. Daemon".
** And another has a CorruptCorporateExecutive end up in the office of one Mr. Devlin, who sends the exec back in time to (supposedly) get richer earlier. The exec ends up instead becoming a janitor in the firm where he should have worked while the janitor he'd previously abused got his old job. It's implied that "Mr. Devlin" makes a game out of eternally tricking the two into switching places, ruining their lives 'for the first time' every time.
* On ''Series/{{Supernatural}}'', [[spoiler:Lucifer's vessel]] is named Nick.
* Invoked in the ''BurnNotice'' episode "Friendly Fire" - Michael presents himself to some credulous Latino gangsters as a mysterious figure dressed in black and red, who seemingly causes explosions with a snap of his fingers and speaks in a very low, calm voice. He calls himself "Luis".
* Jokingly invoked during the riffing in ''[[Series/MysteryScienceTheater3000 MST3k]]'''s presentation of an educational high school short called "Film/{{Cheating}}". As a student is shown getting high marks for a test on which he'd cheated, Tom Servo mimics his teacher saying, "This contract arrived for you from a Mr. Elzebub."
* ''Series/BattlestarGalacticaClassic'' had one Count Iblis during its "War Of The Gods" two-parter. A mysterious visitor to the rag-tag fleet, he uses mysterious powers and miracles to persuade the Colonials to willingly grant him their loyalty, while mysterious beings of light start appearing and the characters start talking about theology. [[spoiler:He's eventually driven off when he accidentally strikes down a protagonist who explicitly rejected his authority.]]
* One of these appears on ''Series/GoodEats'', making a pact with a woman (and eventually her rival) to help her win a cake-baking contest with a new recipe: Devil's Food Cake (and for the rival, Red Velvet Cake).
* ''Series/{{Whitechapel}}'' had a GenderFlipped version in the form of Louise Iver. Which as an added bonus, is also an anagram of "I rouse evil", which is exactly what she does throughout the episodes.
[[/folder]]

[[folder:Music]]
* A common theme in many traditional folk ballads.
* There's a German screamo band that goes by the name of Louis Cyphre.
* For U2's [=ZooTV=] tour in the 90's, Bono introduced the character of [[http://www.canadanne.co.uk/macphisto/ Mr MacPhisto]].
* Every country in The Evillious Chronicles by {{Mothy}} has a name derived from a Prince of Hell.
[[/folder]]

[[folder:Pinball]]
* The "Luci" Premium Edition of the ''Pinball/{{ACDC}}'' pinball table is named after HornyDevil girl Luci, who is heavily implied to be Satan.
[[/folder]]
[[folder:Professional Wrestling]]
* This used to be [=LuFisto=]'s gimmick, [[FridgeHorror or maybe it still is?]] No, most likely she is just insane or really {{obfuscating stupidity}}...are the more optimistic viewpoints.
* In WEW descended a {{fallen angel}} named [[Wrestling/DaffneyUnger Lucy Furr]] who was out to steal the souls of [[BreadEggsBreadedEggs its wrestlers, and its hos, and its wrestlers who were also hos.]]
[[/folder]]
[[folder:Radio]]
* Frequently used in ''Radio/OldHarrysGame'', although not as a twist since we ''know'' which character's Satan. There's sometimes a twist when the detail of who he's disguised as gets held back, instead.
** In more recent episodes, he goes by the name 'Mr. Harrison' when disguised as a human, presumably a reference to 'Old Harry'.
[[/folder]]

[[folder:Theatre]]
* Nick Shadow from the opera ''[[Theatre/TheRakesProgress The Rake's Progress]]''.
* ''DamnYankees'' has Mr. Applegate. Considering what caused Adam and Eve to be kicked out of Eden...
[[/folder]]

[[folder:Video Games]]
* The FinalBoss battle of ''GuitarHero III'' involves a guitar duel between the player and a recently revealed to be demonic manager named... you guessed it... Lou. As a matter of fact, he points out to the band, in some ''extremely'' fine print, a clause stating "Your soul is MINE!" The not-quite-part-of-the-band Guitarist is essentially called down to "Lou's Inferno" (aka Rock 'n' Roll Hell) to save his/her bandmates' asses. They duel to a heavy metal version of [[RuleOfCool ''The Devil Went Down to Georgia''.]] In this case, up until the point the hapless band tumbles to Hell... pardon me, "Lou's Inferno"... there isn't any clear evidence that there's anything otherworldly about him. For all they know, he's just a veteran metalhead who's a little too into it. Given how vanishingly few metal bands who used Satanic imagery ever took it seriously, this lapse of judgment is perhaps forgivable.
* One of the rulers in the "Chronicles of the Sword" side game in ''SoulCalibur III'' is named Demuth Beel Zebus Halteese. Guess which alignment he falls under. Go on, guess.
* Louis Cypher/Cyphre is also the human pseudonym for Lucifer in the ''Franchise/ShinMegamiTensei'' series. He shows up in all of the mainline games as a subtle [[TheChessmaster Chessmaster]]: twice as a blond haired gentleman, once as both a young child and an elderly guy in a wheelchair - in fact the nurses accompanying both could be "him" too - and he's even [[VideoGame/ShinMegamiTenseiStrangeJourney switched genders]] as [[spoiler:"Louisa Ferre"]]. Depending on your spot on the OrderVersusChaos meter, he'll either be your best friend or an inevitable [[TheDragon Dragon]].
** Specifically, ''VideoGame/ShinMegamiTenseiIIINocturne'' (the game in question) had a bonus disc with Dante of ''DevilMayCry'' and a 6th, "maniac" ending, which is what we got. In said bonus disc, you could [[spoiler:choose a 6th path, choosing instead of joining any of the "good" or "evil" characters to screw them all and to meet with Lucifer, who has ''interesting'' ideas about your place in the universe.]] This lets you get the sixth ending, [[spoiler: True Demon Ending. Wherein you join Lucifer and attack heaven, to try and stop the constant destruction and recreation of the millions of alternate Earths -- and the genocide of billions of humans -- by God.]] Although, considering that he has an ObviouslyEvil smile on his face when you make the aforementioned decision, one could make a case for the player being [[UnwittingPawn suckered in]]. Though, to be fair, he gives you a lot of time ''and'' a certain amount of reasons as to why you ''shouldn't'' agree to his plan.
*** In the Freedom ending he tells you to keep your power as the true enemy is still out there. Most likely because both him and Kagutsuchi [[spoiler:compared the Protagonist to Lucifer in the freedom ending.]]
** Lucifer also appears in RaidouKuzunohaVsKingAbaddon as [[spoiler: the "blonde young man"]] and can be fought as a bonus boss in the second playthrough, if you beat the game on the chaos path in the first playthrough. Beat him three times and he becomes [[OlympusMons one of your many minions]]!
** And as a bonus boss in ''VideoGame/DevilSurvivor'' as well.
*** Though it isn't Lucifer, ''VideoGame/DevilSurvivor'' also has the Gigolo. It's less obvious, but it's [[spoiler:Loki]]. He serves the same purpose though...and only reveals himself in two endings out of six. [[spoiler:Loki]] serves a slightly different purpose in Devil Survivor than Lucifer did in other SMT games - he's solely there to screw over [[spoiler:Beldr]]. Again. Once you do it for him, that's when he takes a liking to you and starts feeding you info, mostly just [[ItAmusedMe to see what's going to happen next]].
** His most subtle disguise (relatively speaking) yet is in ''VideoGame/ShinMegamiTenseiIV'', where he appears as [[spoiler:Japanese schoolgirl Hikaru.]][[note]][[spoiler:The name can mean "light" in Japanese, and "Lucifer" can be translated from Latin as "light-bringing".]][[/note]]
** In the [[VideoGame/ShinMegamiTenseiI first]] SMT, there's also Ambassador Thorman. That one's pretty obvious. [[spoiler:But an inversion of the trope as Thor is rarely considered evil, at worst a jerkass.]]
** ''VideoGame/ShinMegamiTenseiII'' also has a weird variation of this trope. While Lucifer himself appears in his usual handsome blond man persona, there's another guy you have to watch out for: [[spoiler:Zayin, your ally who discovers he's actually one-half of Satan (completely different than Lucifer in this series, don't ask). He's TheDragon to the game's BigBad, [[GodIsEvil YHVH]].]]
* The flash game ''Motherload'', in which you play as a mining company whose benefactor is the mysterious "Mr. Natas". A real head-scratcher, that one.
* ''EternalDarkness'' plays a variation, where the BigBad Pious Augustus often masquerades as a human called Paul or Philippe Augustine.
* [[{{Tsukihime}} Kagetsu Tohya]] reveals that unlike the other nightmares, Arcueid's cannot take form like Dark Elesia or Nanaya. Why? Because it's the Crimson Moon and can't take her over... yet. Shiki has a long talk with it under the impression that it's some alternate form of Arcueid, which is kind of true. After awhile it's not only glaringly obvious that this is ''not'' Arcueid. it's even admitted as much. It's much more morally ambiguous than the Devil, but it did try to crash the moon into the Earth at one point.
* In ''VideoGame/GrimGrimoire'', one of the teachers is a TallDarkAndSnarky devil, who doesn't hide that he's a devil at all. And as it turns out, there was an extremely strong horrible demon trapped in the school as well. Who knew?
** However, he subverts parts of this in that his given name, Advocat, doesn't allude at all to his real name [[spoiler: Mephistopheles. Yes, ''that'' [[{{Faust}} Mephistopheles]]]]. Luckily he's actually TrueNeutral and doesn't directly involve himself (and when he does, it's usually to help ''[[FullNameBasis Lillet Blan]]'' in a small way).
* The protagonist of ''AceCombat Zero: The Belkan War'' goes by the callsign Cipher of the Galm (Garm) Team of the 66th Division of the 6th Air Force, and gains the title Demon Lord of the Round Table.
* The story of ''VideoGame/{{Sacrifice}}'' is set in [[HowWeGotHere flashback form]] with main character Eldred telling the tale of the world's destruction at the hands of OmnicidalManiac Marduk to the blind sage Mithras. Once you've cleared out the first nine levels and is done with the backstory, the last, tenth level... well, what trope are you on again?
* A rather strange example of MoralGuardians meddling with the game, The North American version ''StarOcean3'' features a character named Luther. His name is Lucifer in the Japanese version. The weird part is that the game really has no particular reason to make such a change. Religion in general, fictional or otherwise, is avoided.
** In general, however, while specific religious themes aren't harped on, MANY names of antagonists were changed in most StarOcean games for localizations. For instance, Azazel, the original JP name for a [=SO3=] antagonist, was changed to Azazer, as the original refers to a fallen angel of Abrahamic lore, and most of the Ten Wise Men from SO2 had similar changes to avoid sounding overtly religious.
** The PSP port rendered them back to the original names. As for Lucifer/Luther, it could also be a subtle TakeThat to the MoralGuardians by giving the comparison the Luther being related to Martin Luther, the man who kicked off the protestant reformation. Add in the most MoralGuardians are Protestant...
* ''VideoGame/CastlevaniaCurseOfDarkness'' has a priest named Zead who occasionally advises Hector, who turns out in the end to be [[spoiler:Death]]. He uses the SdrawkcabName approach, but to add a twist, he reverses the Japanese pronunciation of his English name.
* In all the IF routes in ''SengokuRance'', a woman named Keikoku with long pink hair that has flower patterns on it shows up. Eventually, one way or another she is revealed as being some sort of evil figure. It's actually difficult to figure out exactly ''what'' she is, though. She isn't human, she's not a demon and she isn't a youkai.
** She's classfied as Monster in [[UltimateShowdownOfUltimateDestiny Free For All]].
* One of these appears in the ''VideoGame/WorldOfWarcraft'' raid instance Ulduar, a vast prison built to contain the Old God Yogg-Saron. Throughout the instance, players hear the voice of Sara, a vrykul woman trapped by minions of Yogg-Saron, calling out to them to help her. When they reach him, Sara spends the first phase of the fight helping and encouraging the players... [[spoiler:and reveals in the second phase that she's really an avatar of the Old God himself. She'd lured the players down through the prison to unlock all the gates and break the final bonds holding him in place.]]
* In ''{{Demonbane}}'', there's a mysterious woman call herself Nya. As story progress, player can see her face briefly change to demonic being with three burning eyes. Eventually, it's reveal that she's [[spoiler:[[CthulhuMythos Nyarlathotep]]]]. It appear again as Father Ny in the Elder Gods ending and as Nyarla in prequel novel.
* ''VideoGame/TheElderScrollsVSkyrim'' features a friendly character you might run into at a bar, by the name of [[spoiler: Sam Guevenne]]. He's Sanguine, Daedric prince of debauchery. [[WhatDidIDoLastNight And you're in for a ride.]] Not all Daedra are [[OurDemonsAreDifferent fantasy analogs for demons]], but [[BigRedDevil it's obvious that this one is]]. He's not all bad, though. While his openly Daedric form ''looks'' like a stereotypical devil, he is (fittingly for his Sphere) more interested in having ''fun'' than in claiming your soul, and gives you a powerful magical artifact as a gift "to remember old Uncle Sanguine."
* In ''AlanWake'' there is a character called Barbara Jager, who probably has no direct connection to BabaYaga.
** Mr. Scratch from ''Alan Wake: American Nightmare''.
* The mysterious stranger in ''RedDeadRedemption'' never actually gives his name (he claims, in a possibly sarcastic tone, to have forgotten,) but he appears in locations that such a SharpDressedMan has no business in being, knows a huge amount about John's past (including the name of one of the random civilians John's gang killed in their outlaw days), calls himself "an accountant, in a way", and in their third encounter John gets fed up and demands answers or "[he] will not be responsible for [his] actions" he calmly tells him "Oh, but you will be responsible". John then shouts "Damn you!", the man replies "Yes, many have", doesn't seem to notice the three bullets John shoots at him and then just vanishes. [[spoiler: This is after a conversation where he muses over what a beautiful spot they're at, which is right where John later gets buried.]] It's not clear who exactly he is; common interpretations are that the man is God, St Peter, Death, or, of course, the Devil.

* [[ManipulativeBastard Doc Scratch]] of ''Webcomic/{{Homestuck}}'', according to WordOfGod (A reference to "Old Scratch").

[[folder:Web Original]]
* There's a piece of literary porn on the 'net about a lawyer's wife whose husband's boss is nicknamed Nate, for ''[[SdrawkcabName Natas]]'', but the real culprit here is his associate named ''Luc'', who seduces her. So she has his full-term kid [[ExpressDelivery in seven months]].
* ''Wiki/SCPFoundation''
** Dr. Alto Clef [[MultipleChoicePast has made many implications about his history]], including being {{Satan}}. [[spoiler: It's implied he reveals this just to screw with Kondraki's mind; he gets a broken neck for his trouble, though after he gets better and is brought in to deal with a troublesome RealityWarper, he proceeds to introduce himself with the familiar Rolling Stones reference (which flies over the punk's head)...]]
** [[http://scp-wiki.net/scp-719 SCP-719 ("Light-Bringer")]]. The otherdimensional being using SCP-719 to communicate with humans has a cult that worships him. In their writings the being is referred to as "The Light-Bringer" (c.f. Lucifer, "light bringing") and "The Morning Star".
* ''TheOnion'''s show ''Dr. Good'', has the creepy plastic surgeon [[SignificantAnagram Dr. Tanas]], who gives increasingly unsubtle hints to his true identity as the show progress.

[[folder:Western Animation]]
* In ''TheDevilAndDanielMouse'', Jan Mouse signs a recording contract with a producer named B. L. Zeebub. Bad move.
* ''WesternAnimation/StarTrekTheAnimatedSeries'' episode "The Magicks of Megas-Tu". An alien satyr named Lucien is revealed to be the Lucifer of Earth mythology. Notably, in this one, Lucifer is actually a ''good guy''.
* ''TheRealGhostbusters'' episode "The Devil to Pay". The Ghostbusters appear on a game show called "Race the Devil", hosted by one "Dib Devlin". The question that lands them a spot on the quiz is "give me two additional names for the Devil"... For some reason, Egon gets a bit suspicious.
** The appearance of Satan himself on a kid's show is unconvincingly averted by this bit of writer wit:
--->'''Winston''': [[MadnessMantra I have sold my soul to the Devil. I have sold my soul to the Devil.]]
--->'''Ray''': Actually, Winston, Dib is a minor demon, not the Devil per se.
--->'''Winston''': I have sold my soul to a minor demon. I have sold my soul to a minor demon.
* Lucius Heinous VII and his son Beezy on ''{{Jimmy Two-Shoes}}''. It's never directly stated, but the implication is obvious.
** It's even more obvious with Lucius Heinous I, who (based on his memorial painting) looks a lot more like the traditional interpretation of Satan.
* In the British/Canadian cartoon ''TheBaskervilles'' the owner of Underworld: The Theme Park is Mr. Boss, whose real name is Nicolas Lucifer III.
* Big D in the ''ClassOf3000'' episode "The Devil and Lil' D".
* The Red Guy from ''WesternAnimation/CowAndChicken''. He was blatantly referred to as The Devil in the pilot.
* ''WesternAnimation/GravityFalls'' features an Eye of Providence-esque demon by the name of [[PunnyName Bill]] Cypher. A relative?
* ''WesternAnimation/RickAndMorty'' has Mr Lucius Needful, who owns a mysterious store that offers magical items for free whose "price" is that they always have some kind of ironic twist attached to them. Rick proves to be extraordinarily GenreSavvy as he asks him outright if he's the Devil upon meeting him. After that, Needful doesn't even bother hiding it and straight-up calls himself the Devil.

[[folder:Real Life]]
* Elizabethan England understood Creator/NiccoloMachiavelli to be a RealLife example of this in its perception of him as an evil schemer [[MurderSimulators responsible for anti-Protestant violence]]. In popular imagination and literature, his first name abbreviated to Nick, and an AffablyEvil character emerged on stage known as a Machiavel which was (mis)pronounced "make-evil''.
