-->--'''ComicBook/{{Wolverine}}''', ''Film/XMen''

StevenUlyssesPerhero finally [[LiveActionAdaptation got a role in the newest blockbuster film!]] Finally, the mainstream audience can be introduced to the awesomeness that is [[AtrociousAlias Grass Man!]]

...Except no one ever calls him that.

Throughout the movie, he's just "Steven Ulysses". We get all of one scene where he hints at casual drug use in college, [[MythologyGag saying his roommates used to call him "The Grass Man"]] with a snicker. Afterwards, they never use that name again, even when he gets [[GreenThumb the ability to control plants.]] Heck, even the end credits refer to the character as "Steven". What the heck just happened?

Simple: "Grass Man" is a name that the general audience ''might'' have a [[WillingSuspensionOfDisbelief hard time taking seriously]], and the [[EnforcedTrope producers knew it.]] Sure, that's what he's been called for [[GrandfatherClause forty years in comics]], but there are ''[[{{Narm}} very poignant]]'' reasons why people still have a hard time disassociating comic books with {{Camp}}iness. [[PrintLongRunners Forty years ago]], "Grass Man" might have been perfectly feasible for a character that can control plants, but nowadays, there's almost no way to use that name around the uninitiated without [[HehHehYouSaidX invoking a snort and a snicker]]. Hell, even a potentially "cool" name like "[[TheyCallHimSword The Sabre]]" or "[[DarkAgeOfSuperNames Dark Wolf]]" might seem a little too superheroic, especially if you're going to be calling someone by that name the whole movie. And on the villain side, it probably wouldn't make sense for someone to go through a traumatic experience and immediately start calling themselves "Dr. Destructo".

However, because the producers don't want to ''completely'' alienate the comic fans which supported the character to begin with, they add a little ShoutOut [[PanderingToTheBase just to appease them]]. "Grass Man" was definitely in the movie, even if that wasn't officially his name. They might even [[ArtifactTitle call the movie "Grass Man"]] without ever calling the ''character'' that. However, sometimes this trope gets taken UpToEleven and the superhero name is never used ''at all''.

In the case of long-running TV adaptations rather than movies, it's not uncommon for the ''writers'' to forget that they're using this trope after a while and accidentally use the character's comic book codename once or twice in a non-ironic fashion. Furthermore, it wouldn't make much sense for the hero to refer to himself and be referred to by his real name when around people who don't know his secret identity, so in those cases [[EnforcedTrope the code name]] ''[[EnforcedTrope has]]'' [[EnforcedTrope to be used]].

Related to MovieSuperheroesWearBlack, NotWearingTights. SuperheroSobriquets, however, may be exempt from this rule, due to the fact that they're used more as a title than a "name".

'''Note: Aversions must be notable. If we try to name every superhero film/media that averts this, [[Administrivia/PeopleSitOnChairs we'll be reading this all day]].'''



!!! {{Film}}

[[folder:The Marvel Cinematic Universe]]
In general, the Franchise/MarvelCinematicUniverse goes out of its way to subvert, lampshade, and defy the concept of a SecretIdentity. None of the Avengers have one--not even Iron Man, who had one for decades in the comics. Tony himself mocks how pointless it is and defies the trope by outing himself in the last scene of [[Film/IronMan1 his first film]] before the end credits.

* ''Film/IronMan'':
** Iron Man himself doesn't get called that name until the end of the first film and it's only used once or twice in the following films where he appears ("I am Iron Man" gets an echo in ''Iron Man 2'' and Nick Fury refers to him as Iron Man once), but the name is also used in specific reference to the suit (i.e. "the Iron Man weapon" or "Tony Stark's Iron Man").
** In ''Iron Man 2'', the words "Comicbook/WarMachine" are only used as an offhanded insult from Tony to James Rhodes. This is lampshaded in the third film, where Tony is incredulous that Rhodey actually adopted War Machine as his codename just from that remark.
** As for the villains, Obadiah Stane is never called "Iron Monger", although he briefly says the word in reference to Stark Industries' role as a weapon manufacturer. Meanwhile, there's Ivan Vanko: a CompositeCharacter of two villains named "Crimson Dynamo" and "Whiplash". He gets called neither in the second film, though the marketing referred to him as Whiplash. In ''Iron Man 3'', Eric Savin and Jack Taggert go by their real names, and are never once referred to as "Coldblood" or "Firepower" (and the Extremis soldiers all have heat powers, so "Coldblood" wouldn't even make sense anyway).
** ''Film/IronMan3'' averts this, with both War Machine and Iron Patriot mentioned as codenames in popular and military use (lampshaded when Rhodey reveals that Iron Patriot "tested better with focus groups.") The Mandarin is also referred to as such, [[spoiler:though the character Ben Kingsley played is ultimately revealed as a DecoyLeader. The real villain, Aldrich Killian, only refers to himself as the Mandarin once]]. This gets even stranger in the short ''[[Film/MarvelOneShots All Hail The King]]'', where it's revealed that [[spoiler: Killian wasn't the REAL Mandarin either, and had stolen the name. The REAL one, though never shown, is naturally miffed at other people stealing his shtick.]]
* ''Film/TheIncredibleHulk'':
** Averted by The Hulk, who is called "Hulk" four times. The first time comes after the Culver University fight, where some college students refer to him as a "big hulk". Later, the military guys chasing the transformed Blonsky through New York mistakenly report that "the Hulk is in the street." Blonsky explicitly uses that name after the Hulk shows up for the final battle and the Hulk himself uses his [[CatchPhrase patented "HULK SMASH!"]] at the end of the fight. In ''Film/TheAvengers'', Bruce Banner notably takes pains not to call his alter-ego "the Hulk", preferring to call him "the other guy" instead. The one time he ''does'' say Hulk, he immediately corrects himself. But no one else has the same qualms.
** "The Abomination" aka Emil Blonsky goes by his given name and there is only an offhand referrence to that title once, when Dr. Sterns tells Blonksky that augmenting him with the Hulk's blood might turn him into "an abomination". ''[[Film/MarvelOneShots The Consultant]]'', in which the name Abomination is brought up but Agent Coulson says "[The World Security Council] ''really'' don't like when you call him that."
* Averted in the ''Film/{{Thor}}'' films, where everyone's "superhero" identities are in fact their real names. Thor himself inverts it in the first movie, as the character once had a civilian identity in the comics, but the movies don't bother. So "Thor" is used all throughout the movie, while the name "Dr. Donald Blake" is the one that only gets [[MythologyGag a few token mentions]].
* In the ''[[Film/CaptainAmericaTheFirstAvenger Captain America]]'' movies:
** The eponymous hero plays with the trope constantly. He only takes the name Captain America as a stage name, not as a superhero. Once he makes the transition to war hero, all of the characters call him Steve or "Captain Rogers" with a few exceptions (once by Bucky, once by Cap himself, and the other time by the Red Skull), and most of those examples are used as humor, irony, or mockery. Further, unlike in the original [[TheGoldenAgeofComicBooks Golden Age]] comics, Cap does officially have the rank of "Captain", and since we've got various characters referring to him by "Captain", it's hard to know if they're using his stage name or military rank. By ''The Avengers'', though, Captain America has become legendary and the name is in widespread use.
** Johann Schmidt gets called "The ComicBook/RedSkull" (by ''Hitler'', no less) one time as an insult, much to his annoyance. For the rest of the movie, only his real name is used. However, when he's mentioned in ''The Winter Soldier'', it's only done by his codename. Technically, this is also true of Montgomery Falsworth, aka "Union Jack", the British counterpart to Captain America. However, Falsworth is not a costumed hero in this movie so there would be no reason to say the name at all.
** In ''Film/CaptainAmericaTheWinterSoldier'': Crossbones is only referred to by his civilian name, Brock Rumlow, though he may take up the name Crossbones in future installments. Similarly, Georges Batroc is never called "Batroc the Leaper". Sam Wilson is called [[ComicBook/TheFalcon "Falcon"]] by Maria Hill in the final battle, and this is also the name of the flight pack model he uses. The "Winter Soldier" codename is invoked frequently, but the heroes stop calling him this once they find out that he is [[spoiler:ComicBook/BuckyBarnes]]. Finally, Sharon Carter is referred to as "ComicBook/{{Agent 13}}" throughout most of the movie, with Natasha only revealing her first name during the movie's last scene.
* From multiple movies, Natasha Romanov's handle of "Comicbook/BlackWidow" never comes up in ''Iron Man 2'', and is only used in ''Film/TheAvengers'' twice. In the first instance, it was spoken ''in Russian'', so anyone watching the film outside of its Russian dub actually only gets to ''read'' the name in subtitle form. Its other brief appearance is on the screen of a dossier Coulson is viewing. It's used all of once in ''The Winter Soldier'', where a HYDRA agent refers to her as Black Widow while telling Rumlow to stop her.
* In ''Film/TheAvengers'', Clint Barton is called "{{ComicBook/Hawkeye}}" all of once by the Black Widow during the Battle of New York. It appears to be his radio callsign, with the name appearing briefly when Coulson is viewing his dossier in the film's beginning. The closest anyone comes otherwise is Dr. Erik Selvig semi-dismissively calling him "the Hawk". During his prior cameo in ''Thor'' it wasn't even alluded to.
* This trope can be applied to the MacGuffin of ''Captain America'' and ''The Avengers''. In the movies, it's called the Tesseract, or "the cube". They never use its comic book name, the "Cosmic Cube". However, it and other {{MacGuffin}}s are collectively known as [[ComicBook/TheInfinityGauntlet Infinity Stones]], a name that ''is'' taken from the comics.
* From ''Series/AgentsOfSHIELD'':
** Franklin Hall and Donnie Gill didn't go by their supervillain names, Graviton and Blizzard, in their introductory episodes... but then again, they weren't supervillains ''yet''. When Gill reappears, it's mentioned that the experiments with his powers had been codenamed "Project Blizzard".
** Raina manipulates a pyrokinetic's ego by suggesting he adopt the name "Scorch," commenting on how nobody knows "Steve Rogers" but "Captain America" is a household name. Everyone who hears it is incredulous at the idea, including the pyro at first, but he warms up to it (pun not intended) and by the time S.H.I.E.L.D. shows up his embracing it is taken as a sign he's getting out of control.
--->'''Coulson:''' [[OhCrap Ah, crap,]] they gave him a ''name''.
** Another episode concerns a device whose name is Russian and translates to "Overkill" in English; there's some snark that something must have been lost in translation but it's generally referred to as the Overkill Device in this and future episodes.
** The first season BigBad is known as "the Clairvoyant"; although almost every character rejects the possibility of actual psychic powers, they keep calling him that because they don't have another name for him. They eventually are able to communicate with him directly, where the Clairvoyant says his subordinates coined the name and he himself finds it a bit overdramatic. Once he drops his cover he encourages everyone to use his real name. (And for the record, [[spoiler:no, he does not have psychic powers; his "omniscience" is based in high-level SHIELD security clearance.]])
** Coulson's team discovers a super-soldier project codenamed "Deathlok", and they soon start referring to the project's subject himself as Deathlok completely unironically. Later in the first season, [[spoiler:it's discovered that there is more than one subject, at which point Deathlok becomes somewhat of a generic label.]]
** Marcus Daniels is never called "Blackout" in dialogue, though eagle-eyed viewers can make out the name on his profile. The source of his powers ''is'' called the Darkforce, however, with requisite lampshading:
--->'''Coulson:''' [[SarcasmMode Because nothing bad ever happens when you're working with]] [[NamesToRunAwayFromReallyFast something called "Darkforce."]]
** Carl Creel is only referred to as being "this absorbing man", but is never actually called Absorbing Man as a name, only as a descriptor. Also, his "Crusher" nickname is only spoken of in the context of his past career as a boxer.
** Bobbi Morse has only used her callsign of ComicBook/{{Mockingbird}} once, in her first appearance.
** The next BigBad goes only by Daniel Whitehall, never his comic name of "Kraken". Inverted with one of his [[TheDragon Dragons]], Agent 33, whose real name is never given.
** Marcus Scarlotti was one of the villains with the Whiplash name in the comics, but is never identified as such here; likely to avoid overlap with the ''Iron Man 2'' villain.
** The real names of [[spoiler:Skye]] and her father were deliberately withheld from the audience in order to hide their identities and the fact that they are even ''from'' the comics in the first place. Eventually their first names are revealed to be [[spoiler:"Daisy"]] and [[spoiler:"Cal"]] respectively, and WordOfGod has confirmed that they're the MCU versions of [[spoiler:Daisy "Quake" Johnson and Calvin Zabo AKA "Mister Hyde"]]. It remains to be seen if either codename will be adopted in the show, though groundwork has been laid for justifying both.
* ''Film/GuardiansOfTheGalaxy'': In general, the movie uses the same aversion as the ''Thor'' movies in that everyone's names are their real ones, but there are a few examples:
** The team's name "the guardians of the galaxy" is a mocking nickname given to the group by Ronan the Accuser. Peter throws it back in his face when they defeat him, with the implication that they may adopt it as a group name.
** Parodied with "Star-Lord", as Peter Quill introduces himself as that, but people just respond with confusion. When the space cops later look at his rap sheet, they comment that apparently the only person who calls Quill "Star-Lord" is ''himself''. Comically, he is ecstatic when, in the last act of the film, someone actually ''does'' call him Star-Lord.
--->'''Rhomann Dey:''' Hey! If it isn't "Star-Prince."\\
'''Quill:''' Star-''Lord''.\\
'''Rhomann:''' Sorry; "Lord." ''[to his partner]'' I picked this guy up a while back for petty theft. He's got a ''code name!''\\
'''Quill:''' Come on, man, it's an ''outlaw'' name.\\
'''Rhomann:''' Relax, pal. [[SarcasmMode It's cool to have a code name. It's not that weird.]]
** Inverted with Drax the Destroyer. In the comics, he's a transformed human named Arthur Douglas. In the movie, he's an alien and Drax is his real name (with the "Destroyer" nickname earned for his RoaringRampageOfRevenge).
** Rocket's full name in the comics is "Rocket Raccoon," but everyone calls him Rocket. It's justified by two reasons: 1) Rocket hates being called an animal, which the name clearly insinuates; and 2) he doesn't even know what a raccoon ''is''.
** Like the Cosmic Cube example from ''Captain America'' and ''The Avengers'', nobody refers to Ronan's hammer as the Universal Weapon (partly because it never comes up; the bigger threat is Ronan himself).
* In ''Series/AgentCarter'', neither of the main villains are called by their codename. [[spoiler:A Black Widow agent]] has no direct reference made to her codename (or any real name for that matter) and is only identifiable by sharing a backstory with [[spoiler:Natasha Romanov]]. The codename of [[spoiler:Doctor Faustus]] gets a nod when he's shown reading [[Theatre/DoctorFaustus his namesake play]]. Codenames are also referenced when Peggy teams up with her war buddies in the Howling Commandos and "Dum Dum" Dugan realizes she never had a nickname like the rest of the squad. He suggests "Miss Union Jack" (see in the Captain America section above), which she declines.
* Promotional material for ''Series/AKAJessicaJones'' refers to the Purple Man by his last name (spelled slightly differently from the comics), Kilgrave. Of course, [[NamesToRunAwayFromReallyFast "Kilgrave" is a threatening enough supervillain name on its own]].

[[folder:X-Men Film Series]]
* This trope is played with all over the place. Codenames are something of a plot point; it's shown that the concept of a "true name" began with Xavier's eponymous "first class". However, it's originally used in playful jest and doesn't become serious until Magneto insists upon being called by that name at the very end of the film. In later movies, mutants seem to adopt codenames as their "true names" as evidenced when "Marie" changes her name to Rogue or when Magneto asks "John" what his real name is and he starts calling himself Pyro. Other than that, the codenames are used as {{Mythology Gag}}s or {{Futureshadowing}}.
** Cyclops' codename is mentioned but he mostly goes by Scott throughout all of the movies.
** The name "Prof. X" is only used twice in both ''Film/XMenFirstClass'' and [[Film/XMen the series]], and Xavier brushes it off.
** Jean Grey and Kitty Pryde never use codenames in the films. While their comic counterparts went through a few over the years, they usually go by their real names anyway (a rarity for superhero comics).
** {{Magneto}} is often referred to as "Erik", although only by Xavier and Mystique, his oldest friends.
** {{Wolverine}} goes by the name Logan almost exclusively and even mocks people with codenames. Stryker seems to be the only one who wants to call him Wolverine, which was more of a military-style CodeName. In the first film, it is mentioned that "The Wolverine" is a nickname he uses in his cage-fighting career, and in ''Film/XMenOriginsWolverine'' he's inspired to take the pseudonym by a {{Native American|Mythology}} folk-tale his wife tells him.
** The Blob never gets called by that name. The best we get is a LampshadeHanging where he mistakes Logan's [[VerbalTic "bub"]] for that name, and sees it as an insult.
** The name "Comicbook/{{Gambit}}" is used a few times, though it's stated to be a prison nickname he was given by Stryker's guards.
** "Bobby" has no codename in the first movie, introduces himself to Wolverine as Iceman in the second film, and is then called Bobby throughout the rest of the series until a brief moment in which Pyro picks a fight.
** Colossus was referred to by his codename by Wolverine as they walked out of the Danger Room near the beginning of ''Film/XMenTheLastStand''. Beforehand, Wolverine calls him Tin-Man as a joke.
** The name Nightcrawler is only mentioned when "Kurt" expounds about his time in the circus.
** Angel (Warren) and Beast (Hank) never use codenames in ''Film/XMenTheLastStand''. Hank does eventually use the name towards the end of ''First Class'', however.
** Subverted and played straight with Jimmy in ''Film/XMenTheLastStand'' as his profile indeed shows his alternative alias of "Leech", but he's never called that by anyone nor does he refer to himself as such.
** Darwin from ''[[Film/XMenFirstClass First Class]]'' is actually a nickname which happens to fit his powers, and his real name (Armando) is never referenced.
** It gets a bit tricky with Angel (the ''First Class'' member as opposed to the one mentioned above); in the comics, her real name ''and'' code name are both Angel, but she takes the codename "Tempest" when she loses her powers and gains PoweredArmor. In the movie, though, she explicitly states that Angel is a stage name.
** Lady Deathstrike is never used. Her real name (Yuriko) is only mentioned in passing.
** ''Film/TheWolverine'':
*** Played straight with the adamantium PoweredArmor that is not explicitly called Silver Samurai. The moniker of Silver Samurai was named after a suit of samurai armor that serves as a LegacyCharacter for the Yashida generations.
*** Played with for Viper, who never calls herself "the Viper" but does says she's ''a'' viper.
*** Played straight with The Hand (mainly linked to the Film/{{Daredevil}} / Film/{{Elektra}} franchise, and ownership of those rights reverted back to Marvel before the film was finished), who are referred to as "The Black Clan" and led by Harada.
*** Wolverine ''does'' use his codename, however.
---->'''Shingen''': What kind of monster are you?!\\
'''Logan''': [[TitleDrop The Wolverine!]]
** ''Film/XMenDaysOfFuturePast'':
*** The ''X-Men'' series has a long tradition of ignoring this trope, but now it goes over the top. When Wolverine tells Xavier about his future, he advises him to search for people with certain names: Scott, Jean... and "Storm." Having just read Logan's mind, Xavier certainly would know who he's talking about, but still.
*** The new BadFuture X-Men never have their real names used (with the exception of Bishop). Of course, in the comics, he's a strange case; from the future and known ''only'' as Bishop for the longest time, he eventually took the name Lucas Bishop. Which we should consider his 'real name,' and if ''either'' is what his momma named him when he was born, is hard to know.
*** It's also {{played straight}} a few times. Quicksilver is never called by that name, for instance.

[[folder: The Dark Knight Saga]]
* With the series angling for a less outlandish and more "grounded" depiction of the Batman mythos, the films naturally use this trope extensively:
** The Scarecrow is almost exclusively referred to by his last name Crane. The only times you ever hear the word "scarecrow" are 1) when one of Crane's victims, a delirious Carmine Falcone, utters the word over and over again, and 2) when Crane briefly calls himself "Scarecrow" while under the influence of his own gas.
** In Harvey Dent's case, the name Two-Face is used exactly once, in reference to an old, derisive nickname given to him by the corrupt cops he used to investigate.
** Creator/{{Anne Hathaway}}'s portrayal of Selina Kyle is never once even referred to as ComicBook/{{Catwoman}}, and out-of-universe, even early press releases only referred to her as "Selina Kyle," fueling speculation that she would not be using a costumed identity at all in the film. The only time "Catwoman" is ever close to being mentioned is a newspaper headline reading "The Cat Burglar Strikes Again" when Bruce is showing Alfred the background information he's pulled up on her. This may have become the best-known and most prominent example of the trope, to the point that various bloggers and reviews go out of their way to refer to the character as "Selina Kyle" and not "Catwoman". This makes sense when you consider [[Film/{{Catwoman}} the last time the character was referred to as "Catwoman" on screen]], and how hard it flopped.
-->[[http://www.mdjonline.com/view/full_story/19463316/article-REVIEW--Batman-saga-ends-with-%E2%80%98The-Dark-Knight-Rises%E2%80%99?instance=special%20_coverage_right_column "...cat burglar Selina Kyle (Anne Hathaway)...She is essentially Catwoman, but is never addressed as such."]]
** John Blake, the young police officer who aids Batman throughout the film [[spoiler:and is implied to become his successor after Bruce Wayne's apparent death? Turns out his EmbarrassingFirstName is ''ComicBook/{{Robin}}''.]] There is no comic character by the name of John Blake, and he never adopts a costumed identity of any kind in the film, with the broadstrokes similarities basically boils down to [[spoiler:his backstory as an orphan, his apparent status as Batman's successor, and his vaguely sidekick-like role in assisting Batman throughout the film,]] making him perhaps the loosest adaptation in the series.
*** John Black actually appears in a single panel of a comic, [[http://www.cracked.com/blog/advanced-batman-theory-why-nolan-will-kill-bruce-wayne_p2/as pointed out by this Cracked article.]]
* Batman's vehicle, the Tumbler, is never referred to as the Batmobile, either the black version shown in the first two films or the unpainted Tumblers driven by Bane's mercenaries in the third. However, his motorcycle and flying craft both receive bat monikers: the Batpod and the Bat (as opposed to the usual comics names of Batplane or Batwing), respectively. If "sounding less silly" was the objective here, names like "Batpod" and "Tumbler" are a lateral move at best.
* The aversions in the series, meanwhile, are as follows:
** Batman and Ra's al Ghul are commonly referred to as such. Oddly enough, in the comics, Ra's al Ghul is essentially the character's real name (it's complicated) but in the movie [[spoiler:his real name is Henri Ducard]].
*** In Batman's case, the film uses a mix of "Batman" and "''the'' bat-man" to refer to him. The latter is generally less used in popular culture these days, but it sounds a tad bit less outlandish and treats the word "Batman" as less of a guy's nickname and more of a thing or a creature like "the snowman" or "the boogeyman," which fits in line with the whole angle of being a scary monster that terrorizes criminals.
** "SelfDemonstrating/TheJoker" has ''no'' known identity other than his Codename.
--->'''Gordon:''' Nothing. No matches on prints, DNA, dental. Clothing is custom, no labels. Nothing in his pockets but knives and lint. No name, no other alias.
** Like the Joker, Bane never has his true name revealed in ''The Dark Knight Rises'', and he goes by "Bane" exclusively, an element which is also true to the comics. It helps that, compared to names like "Mr. Freeze" or "the Mad Hatter", it's probably one of the easier names to use without raising too many eyebrows.

[[folder: Spider-Man Films]]
* An entire scene played for laughs in ''Film/SpiderMan2'' was dedicated to J. Jonah Jameson coming up with a good nickname for DoctorOctopus, only for him to mostly go by his real name or the nickname "Doc Ock" for most of the movie, as well as the real life advertising and merchandising.
* ComicBook/{{Venom}} is known only by his real name, Eddie Brock, throughout all of ''Film/SpiderMan3''. Similarly, Flint Marko is generally known by his real name for most of the film until a reporter calls him "the Sandman" during the final battle.
* While ComicBook/NormanOsborn was called "Green Goblin" multiple times in [[Film/SpiderMan1 the first movie]], when it came time for his son Harry to adopt that persona, the name was never uttered. In fact, promotional material called him ''New Goblin'', a name that was never used in the comics. The closest Harry comes to being known as the Green Goblin is when Peter mockingly calls him "Goblin Jr.". Harry himself strips most of the goblin styling out of the hardware, going for basic armor and a hoverboard in place of the spiky hang-glider (which [[FridgeBrilliance makes sense]], given that [[SpikesOfVillainy those spikes]] ''[[HoistByHisOwnPetard killed]]'' his father...).
* Averted in ''Film/TheAmazingSpiderMan''. The mutated Dr. Curt Connors is referred to as "the Lizard" several times. Spider-Man himself, of course, is another clear aversion.
** Played straight and averted in the [[Film/TheAmazingSpiderMan2 sequel]] though. Spider-Man is called such very frequently. Electro refers to himself as such even when he's just being tortured and continues to when he becomes a proper villain. [[spoiler:Harry,]] however, isn't called the Green Goblin at all. The Rhino gets very little screen time but is only identified by his civilian name (though he calls himself The Rhino). We also have "Felicia" but she doesn't become Black Cat within the film.

[[folder:Other Films]]
* During the live action film adaptation of ''[[Anime/NeoHumanCasshern Casshern]]'', the titular hero only refers to himself as "Casshern" once, and it isn't even near the climax of the movie.
* The original ''Film/{{Hulk}}'' movie also hardly used the term "hulk", the characters preferring to call him Bruce Banner, or "Angry Man". His father was never a supervillain so he never had a codename to begin with.
** His father was kind of a CompositeCharacter, with powers similar to the Absorbing Man's. He even turns briefly into an electrical humanoid like old Hulk's foe Zzzax. [[JustifiedTrope Think about which of those names would have been]] ''[[JustifiedTrope less]]'' Camp...
** In the DVD commentary, Ang Lee notes that he didn't want to call him "Absorbing Man" and briefly calls him "Partaking Man", coming from David Banner's line: "I can partake in the essences of all things." But this name is never used in the film itself either.
* The ''Film/FantasticFour'' movies, (including [[Film/TheFantasticFour the Roger Corman one]]) rarely mention the codenames of the heroes and never refer to Victor Von Doom as DoctorDoom (this is actually in keeping with the nature of the original series since none of the characters had a SecretIdentity). Resident clown Johnny makes up the codenames on the spot when being interviewed, thus [[VitriolicBestBuds explaining the apparent cruelty]] of Ben being named "The Thing".
** Oddly, "Doctor Doom" would seem to be a perfectly sensible thing to call a person [[MorallyAmbiguousDoctorate with a doctor's degree]], whose last name is "Doom"[[labelnote:*]]technically "von Doom", but people Anglicise such names in all sorts of different ways[[/labelnote]]. In some of the dubs (the Brazilian one, for example), his line "Call me Doom" is changed to "Call me Doctor Doom".
* ''Film/KamenRiderTheFirst'' and ''[[Film/KamenRiderTheNext The Next]]'', DarkerAndEdgier modernized retellings of [[Series/KamenRider the original series]] and ''[[Series/KamenRiderV3 V3]]'', never use the name "Kamen Rider"; Takeshi Hongo and Hayato Ichimonji are called Hopper 1 and 2 respectively, while Shiro Kazami is simply called V3 (which, in the movie's universe, stands for Version 3). This is in line with the majority of modern ''Franchise/KamenRider'' TV shows; see below.
* ''Film/GhostRiderSpiritOfVengeance'' never refers to [[spoiler:Carrigan]]'s character as [[WalkingWasteland Blackout]], which was his name in the comics.
** Johnny himself only ever refers to his firey-headed alter-ego as the Rider.
** In the first ''Film/GhostRider'' movie, Ghost Rider is mentioned quite a bit. When [[spoiler: Sam Elliot]]'s character is revealed as the original Spirit of Vengeance, the name Phantom Rider is not mentioned. This is likely due to the comic character being obscure, the reveal happens not long before the character leaves the film, and the characters have little in common.
* While not a traditional superhero, {{Tarzan}} is a pulp hero who was an inspiration for the superhero genre and shares many elements. That said, in ''Graystoke: The Legend of Tarzan'', he never goes by his more famous moniker but instead is called John or Lord Graystoke. Tarzan is never mentioned except for the title.
* In ''Film/ManOfSteel'', Clark/Kal-El is never ''directly'' called Film/{{Superman}}. At one point, Lois almost says it before being cut off, and a soldier refers to him by the nickname to the confusion of his commanding officer. Presumably the soldiers got it from Lois.
* In ''Film/RoboCop2014'', after his conversion into a cyborg, Alex Murphy is only called "[=RoboCop=]" twice: Once by [[Creator/SamuelLJackson Pat Novak]] as a propaganda catchphrase, then later by his partner Lewis as a joke ("Good Cop, [=RoboCop=]"). Otherwise, he's mostly referred to by his real name, as unlike in the original trilogy, the fact that he's Alex Murphy is a matter of public record.
* In ''Film/ThePunisher2004'' The Punisher spends most of the movie being called his first or last name, it is an origin story. There are only two references to his code name. The first is before the final battle, when he says what he's doing isn't vengeance but ''punishment''. The second is the last line of the movie, where he says "Frank Castle is dead. Call me...The Punisher."
* ''Disney/BigHero6'' inverts it--we never learn the real names of Honey Lemon, Wasabi, and Gogo Tomago. Then again, we never learned in the comics if "Wasabi No Ginger" was an alias or not, and even ignoring his RaceLift, "Wasabi" is stated to be a nickname. Likewise, given their Race Lifts, it's equally unlikely that Honey and Gogo's real names are repsectively "Aiko Miyazaki" and "Leiko Tanaka"; in fact, regarding the latter, according to [[WordOfSaintPaul Gogo's voice actress, Jamie Chung,]] Gogo's first name is [[spoiler: Ethel]].
* ''AvengersConfidentialBlackWidowAndPunisher'' never sees Elihas Starr called "Egghead".

* In the 1989 ''ComicBook/{{Watchmen}}'' [[Script/{{Watchmen}} script]] by Sam Hamm, all the superheroes in the ColdOpening are referred to with codenames except Adrian Veidt. In the main action, when Nite Owl and the Silk Spectre come back into superhero action, they are still respectively named Dreiberg and Laurie in descriptive actions and dialogue headers. The name Ozymandias goes unused, but it's justified- Hamm's version of Veidt was never a superhero himself. His only involvement in the pre-[[SuperRegistrationAct Keene Act]] days was as a financier/quartermaster to the team.

!!!Non-film examples

[[folder: Comics]]
* When introduced, the UltimateMarvel version of Emma Frost did not use the "White Queen" cognomen, as she (at first at least) had no connection to the Hellfire Cub.
* In ''{{Nextwave}}'', none of the members use their code names except for The Captain, and that's only because nobody knows his real name. Machine Man actively mocks Monica's attempts to use them stating that Tabby's (Boom-Boom) sounds stupid, hers (Photon) sounds non-threatening, and his own (as well as his real name which is just a model code) doesn't give him much of an identity.
* The ''ComicBook/{{Runaways}}'' started off with some code names, but dropped them almost ''immediately,'' except for one who insisted on being called "Princess Powerful." (note that she's a 12 year old girl...) Just as well, their code names sucked. The dinosaur still kept the name Old Lace to go with Gert's soon abandoned "Arsenic" codename, but anyway, she's a dinosaur, she does not have a "normal" name.
* One of the reasons that ''Comicbook/BatmanTheDarkKnightReturns'' is considered a notable move towards "Grim and Gritty" storytelling in comics is that it manages to go the entire story without referring to any of the superheroes (other than Franchise/{{Batman}}) by their code names, thus making it easier to put the story in a real world context.
* ''ComicBook/SecretSix'': Catman simply goes by his civilian identity of Thomas Blake.
* Very briefly during the ''{{Knightfall}}'' saga of 1993-1994, there is a storyline in which, shortly after the defeat of Bane, one of Gotham City's mobsters enlists the services of "Mekros" to take down Batman. Nobody ever learns Mekros's real name (the mob boss even refers to him as "Codename: Mekros", which is also the title of the story) or even sees his face, because he is a masked, cybernetic, brainwashed assassin who is a product of the CIA's legendary "MK-Ultra" project from the Cold War (which gets a ContinuityNod a couple of years later when Batman faces off against a woman who is the product of that same program, although Mekros is never named again). However, Mekros himself never uses the name Mekros, for the only reason he ever speaks at all is because he's been programmed by mind-bending drugs to endlessly recite passages from Machiavelli's ''ThePrince'', the most prominent of which is "Only the Phoenix survives chaos." Thus, more naive readers could have been forgiven for assuming his codename was "The Phoenix."
* A one-off {{Superman}} villain in the early 2000s eschewed giving himself an alias, instead using his given name, "Gabriel Van Daniken." He even mocks the practice of villains giving themselves code names:
-->"You think just because I put on this battlesuit, and threaten to poison the water supply, I have to give myself a ridiculous-sounding alias? Get a grip, Superman. I'm thirty-five years old!"
* Done via {{retcon}} for [[ComicBook/GreenLantern Hal Jordan]]'s nemesis, SelfDemonstrating/{{Sinestro}}. "Sinestro" was originally just his supervillain title (an obvious play on "sinister"), but as he was fleshed out as a fallen Green Lantern who went rogue, it was decided that "Thaal Sinestro" was actually his real name. Calling him "Sinestro" is the equivalent of calling SelfDemonstrating/LexLuthor "Luthor".
* GreenArrow: During the 80s run by Mike Grell when he lived in Seattle, Ollie abandoned most of the "superhero" trappings of his life, including the name "Green Arrow". In the entire 80-issue run, he's never referred to by that name. People usually call him [[SecretPublicIdentity Ollie]] or "That RobinHood lookin' dude."
* Played with by ComicBook/{{X 23}}: She wasn't even given a real name until she was thirteen years old, when her dying mother, Dr. Sarah Kinney, named her Laura. Until that point, she was either referred to by her Facility code name, X-23 (derived as her being Sarah's 23rd attempt to create a female clone), or various insults (particularly as being an animal) to dehumanize her. Her official codename with the X-Men, Talon, is almost never used or referenced. Most of her friends, loved ones and teammates just call her Laura, and occasionally they'll use "X" as a sort of nickname. X-23 is used much less frequently within the books, though is how she's typically marketed.

[[folder:Live Action TV]]
* In ''{{Smallville}}'':
** Clark Kent is never referred to as Superman, though the word is mentioned multiple times in reference to Friedrich Nietzsche. The traditional "Superman Created by Jerry Siegel and Joe Shuster" message appears in the intro.
** Because of its {{Prequel}} state, ''most'' characters aren't referred to by codenames, as the incidents that led to them adopting these names haven't happened yet. GreenArrow is the first to do so, and we'd known him for more than a full season when he started using it.
** Slade Wilson gets a Marvel movie-style codename treatment: as a GeneralRipper and not a supervillain, "Comicbook/{{Deathstroke}} the Terminator" is never uttered. However, after [[UnexplainedRecovery coming back from a should-have-been-fatal injury]], he said that "the reaper can swing his sickle at me, but I'm beyond death's stroke now." Also, because the ''WesternAnimation/TeenTitans'' cartoon version is so well-known, ''way'' more people are on a FirstNameBasis with him than you'd expect with a general. He is pretty much just called Slade.
** It takes a weird turn when Clark finally becomes a full time but covert crime fighter and is dubbed with the comparatively unimpressive name "The Blur", which is used frequently even by him.
** Clark ''finally'' starts using the Superman persona in the GrandFinale, and by the epilogue [[TimeSkip seven years later]] his alter ego is known to the world by that name[[spoiler:, but "Superman" is used to refer to him only exactly once by Chloe.]]
* The Heisei-era[[labelnote:*]]post-1998[[/labelnote]] ''Franchise/KamenRider'' series vary in this respect, asserting the autonomy of their own universes from each other (at least until ''Series/KamenRiderDecade'' screwed with their timelines and the subsequent team-ups), with only a handful of series actually calling their warriors "Riders:"
** [[Series/KamenRiderKuuga Kuuga]] was frequently referred to as ''yongo'' (No. 4), in reference to his being the fourth "unknown being" the police force encounters, lumped with the villainous Grongi. (In fact, one of his modes is Unknown Lifeform No. 2; The white Growing Form and the red Mighty Form aren't known to be the same guy by the authorities at first.) Only a few people know the term "Kuuga," and the term "Kamen Rider" doesn't exist outside the opening credits.
** [[Series/KamenRiderAgito Agito]], a loose sequel to ''Kuuga'', has its hero initially confused to be a returning Kuuga/Yongo/No. 4, and was unique in the respect that [[spoiler: a handful of chosen people implanted by the Seed of Light can become Agito themselves.]] So Agito is not so much a unique warrior of justice than [[spoiler: a step in human evolution]].
** Ironically, ''Series/KamenRiderRyuki'' uses it plenty, in a series where what it means to be a Rider is ''very'' different. A Kamen Rider is one of your opponents in the Rider War, and ThereCanBeOnlyOne in the end. [[OnTheNextEpisodeOfCatchPhrase If you don't fight, you won't survive]]!
** [[Series/KamenRiderFaiz Faiz]] was never referred to as a Rider, and neither were the similarly-themed Kaixa and Delta systems and their users. When Kaixa first appears, the side-characters are surprised to see "another Faiz," not "another Rider." The series being a [[GreyAndGrayMorality really ambiguous world]] as it is, [[spoiler: with these systems created by the more-megalomaniac elements of the Orphenoch race (here again, another step into human evolution)]], it probably fits.
** Averted in ''Series/KamenRiderBlade.'' The term is used like in any of the early series, with a guy who wants to write about them as one of the supporting characters. It is (perhaps intentionally) hard to tell if he means ''these'' Riders (active for a little while pre-series) or ''all'' Riders when he talks of the deeds of Riders past. On top of that, the belts are actively called "Rider Systems" by their creators
** [[Series/KamenRiderHibiki Hibiki]] and his fellow warriors are precisely called "Oni", '''''never''''' "Riders." This being an adaptation of another independent Ishinomori series (''Ongeki Hibiki'') reworked as a Kamen Rider series, it is the [[BrokenBase source of contention among the KR fandom]].
** ''Series/KamenRiderKabuto'' is a noteworthy aversion, since the term is built into the show; the {{Transformation Trinket}}s are called "Masked Rider Systems", and can [[MultiFormBalance form-change]] between the heavily armored Masked Form and the much more agile Rider Form.
** ''Series/KamenRiderDenO'' also rarely, if ever, uses the term outside crossovers.
** [[Series/KamenRiderKiva Kiva]] (and for that matter, Saga and Dark Kiva), were considered as "armors" to be worn by the villainous Fangire leaders/kings when their Fangire forms are not enough. And for that matter, the secondary Rider (the IXA system) was never called that as well. The "IXA System" was referred to, but not "Kamen Rider Ixa" as a name. "Kamen Rider" itself was rarely heard - when Ixa's first seen user says "My Rider System is much stronger than his," this may be the only time. ''Kiva did'' have the same head writer as ''Series/KamenRiderFaiz.''
** In ''Series/KamenRiderDouble,'' the people of the city gave their hero the name Kamen Rider. (Past Rider knowledge, or due to their hero having a CoolBike and wearing a helmet, making him obviously a 'masked rider?' Good question.) and ''never'' use the name Double. People in the know primarily use "Double" and not "Kamen Rider." (This means the full title "Kamen Rider Double" isn't something you hear much or at all outside teamups.) Shotaro and Philip have adopted the "Kamen Rider" title and are protective of it - initially it's just for them, but after [[ReunionShow meeting some others]], they're willing to consider you a Rider if you uphold the ideal. Riders aren't just anyone in a shiny suit, they're heroes who fight "those who make the city cry." [[EvilCounterpart Villains with transformed states that happen to have bug-eyes and antennae]] are ''not'' Riders to them and they'll make that known right away.
** Later series played with how the name "Kamen Rider" came to be. In ''Series/KamenRiderFourze'', {{Goth}} Tomoko was aware of past Riders as an urban legend, and so applied it to Fourze ("rider" never comes up when the suit's being explained to the hero at first.) and later Meteor. In ''Series/KamenRiderOOO,'' Kougami seems to know about Riders, so Birth is "Kamen Rider Birth" (it's even in the suit's instruction manual!) but OOO is only called a Rider during crossovers.
** ''Series/KamenRiderWizard'' plays by the rules of the early 2000s' series. People who know him call him Wizard (in English) as opposed to "the ring-bearing wizard" ("wizard" in Japanese, as ''mahoutsukai.'') The term "Kamen Rider" has yet to come up in any way outside teamups. The Rider-like mystery figure that gave him his [[TransformationTrinket Wizardriver]] is known only as the ''shiroi mahoutsukai'' ("White Wizard"), and when Kamen Rider Beast arrives, it's like Faiz all over again: people are surprised to see another 'wizard.' He even introduces himself as "the wizard Beast", while the villains call him the ''inshie no mahoutsukai'' ("Ancient Wizard"), or "[[GratuitousEnglish Archetype]]".
*** This brings up an interesting point: even if a character does not share an origin with any other Rider, and the term never comes up and never has a reason to, when he finally meets other Riders, he ''will'' know the term, maybe even using it as if he always has. Nobody ever says "Kamen who?" except in ''Fourze'', where again, Tomoko applied the term to Fourze and Wizard due to their similarity to Riders past. Fourze introduces the term to Wizard on their first meeting, and the latter gladly adopts it because the idea of "masked heroes who fight humanity's enemies in secret" [[RuleOfCool sounds pretty cool]]. Meteor actually gets mildly offended at Wizard's flippant attitude, saying "Don't take the Kamen Rider name so lightly!", but Fourze calms him down.
** Played with in ''Series/KamenRiderGaim'', where the local DJ gives our hero his name... but that name is ''Armored'' Rider Gaim (as an ''armored'' member of the Team ''Gaim'' dance crew, where such crews are called "Beat ''Riders''"), and "Armored Rider" becomes the term used for the series' warriors instead of "Kamen Rider". Like with other shows, the phrase "Kamen Rider" is used in crossovers, though Gaim ''is'' one of the rare ones that goes "Kamen Who?" at first. It ends up being FridgeBrilliance, as most of ''Gaim'''s Armored Riders are not truly heroic, so it becomes pretty clear that the series may have many characters in armor but only ''one'' true Kamen Rider.
** Averted in ''Series/KamenRiderDrive'', where the name is used regularly; the monsters coined it for the previous wielder of the Drive powers, and the current Drive (along with the audience) first hears it in the context of "OhCrap, we've got another one after us now?" Funnily enough, this is the series where "Kamen Rider" is an ArtifactTitle, as while the previous Drive followed Rider tradition and rode a motorcycle, the current Drive does not.
** Though it's said in the movie section, just for the sake of completeness: ''Film/KamenRiderTheFirst'' and ''Film/KamenRiderTheNext'' never use the term. [[NebulousEvilOrganization Shocker]] calls Riders 1, 2, and V3 "Hopper version [number]" only, and no name is ever used by people who don't know those names, dialogue written so as to not make it awkward that they don't.
* In ''Series/TheIncredibleHulk'' TV series, reporter Jack [=McGee=] and his readers often use the name "the Hulk," but most characters (including the Hulk's alter-ego David Banner) just say "the creature."
* ''Series/{{Arrow}}'', a CW series based on GreenArrow:
** That name isn't used until halfway through the first season, when ''Malcolm'' [[BigBad of all people]] suggests it during a dinner conversation, [[ItWillNeverCatchOn only for Ollie to shoot it down as "lame"]]. He also isn't initially called "Arrow" - he spends the first season being referred to as "The Hood" after his costume design, or just "the vigilante," and has to specifically ask people to start calling him The Arrow after he takes up a ThouShaltNotKill policy in the second season. It has been hinted by {{Word of God}} that he will eventually be called "Green Arrow".
** Zig-zagged with Deadshot, aka Floyd Lawton, who is known to the CIA by that codename, but is mostly referred to by his real name.
** Count Vertigo, reimagined as a drug lord, goes by the Count with the drug he peddles called Vertigo. In the second season however, he officially starts calling himself Count Vertigo.
** Firefly never uses a codename but it is the name of the team of firefighters he was a part of.
** Perhaps the strangest example is Merlyn the Archer. In the comics that's a code name he chose due to his obsession with Arthurian myth, in the series it's his real name. His "Dark Archer" persona is only ever named in advertising materials for the show.
** Barton Mathis is referred to as Dollmaker, and is justified in this case. In the show, he's a flat out serial killer rather than a supervillain, and "Dollmaker" was the name given to him by the media in reference to the manner in which he murders his victims.
** A.R.G.U.S. refers to Slade Wilson by the codename "Deathstroke", but the name didn't exist during the island flashbacks and he and others generally use his real name in the present.
** [[spoiler: Sara Lance]] does use the name "The Canary", a name she chose after joining [[spoiler: The League of Assassins]], instead of the comics ComicBook/BlackCanary.
** Bronze Tiger also breaks the rule.
* ''Series/{{Gotham}}'' plays with this: Bruce Wayne is still a kid and not a superhero yet, so he's not called Batman. Selina Kyle is already a thief, but instead of Catwoman, she's just called Cat, [[MythologyGag a nod to the fact that Catwoman was originally just called "The Cat."]] Oswald Cobblepot is nicknamed "The Penguin", but [[BerserkButton he really doesn't appreciate being called that]] and most people just call him "Cobblepot." Similarly, Edward Nygma is just called "Nygma."

[[folder: Toys]]
* Although the ''Film/{{Hellboy}}'' films avert this trope, the toyline for the second movie does not. The first movie's toys, sold only in specialty shops, were sold under the "Hellboy" title, and featured the character's name on the packaging; the second movie's toys, sold in Toys R Us, were apparently from the movie "HBII," and the main character was "Red."
* The movie toys for ''Film/KickAss'' [[http://www.oafe.net/yo/mez_kaka.php go out of their way]] to avoid putting the word "ass" anywhere on the packaging. The toys for the second movie went so far as to have "uncensored" package variants sold as an exclusive.

[[folder: Western Animation]]
* DCAnimatedUniverse:
** In the ''WesternAnimation/BatmanTheAnimatedSeries'' episode [[Recap/BatmanTheAnimatedSeriesE25TheClockKing "The Clock King"]], the villain never identifies himself as the ClockKing, nor in his next season episode, [[Recap/TheAdventuresOfBatmanAndRobinE8TimeOutOfJoint "Time Out of Joint"]] The only one who calls him that is Commissioner Gordon because this MythologyGag earlier:
--->'''Batman:''' [[StockPhrases I'm here to clean your clock]], Fugate.\\
'''Fugate:''' Don't count on it, Batman. When it comes to ''clocks'', I am ''king''. ''[[GratuitousFrench En garde!]]
** However, Robin calls him "Clock King" in "Time Out of Joint", and in the ''WesternAnimation/JusticeLeagueUnlimited'' episode "Task Force X", Colonel Flagg presents him as "Temple Fugate, a.k.a. The Clock King" to the rest of the Task Force.
** In ''Batman the Animated Series'', Count Vertigo is known simply as "Vertigo", which is his CodeName in the Society of Shadows.
*** In ''The New Batman Adventures'', Catman just goes by Thomas Blake. He also wears a [[MovieSuperheroesWearBlack black outfit]] rather than his colorful comic book costume.
** The MartianManhunter is only called by that name once in all five seasons of ''WesternAnimation/JusticeLeague'', only being referred to as J'onn or "the Martian."
*** Though again, this may simply be keeping up with the comics, where the rest of the League has used his name almost solely for some time. Similarly, Franchise/WonderWoman is usually just "Diana" to the others, both in the comics and {{Franchise/DCAU}}.
** ComicBook/{{Aquaman}}'s brother [[CainAndAbel Prince Orm]] never adopted his moniker of Ocean Master. In fact, BruceTimm flat out said he considered Ocean Master to be too silly a name to take seriously.
* ''WesternAnimation/XMen'':
** Jean Grey is never called Marvel Girl. But it had been a long time since the comic book version had used a codename anyway.
** Zebediah Killgrave also never uses the name Purple Man. It helps that Killgrave is a pretty badass last name in its own right.
* Due to NeverSayDie, DC villain Comicbook/{{Deathstroke}} went by his civilian name "Slade" throughout the animated ''WesternAnimation/TeenTitans'' series. (It probably helps that "Slade" sounds like a codename without the "Wilson".)
** Especially if you don't know they're saying his name (Slade), and instead think they're saying the past-tense of "slay" (Slayed.)
** In fact, the popularity of the ''Teen Titans'' cartoon and its version of him means that (a) in ''any'' DC series he's required to show up, and (b) he'll be called Deathstroke once or twice to get it out of the way and he'll be Slade from then on. In ''YoungJusticeInvasion,'' he was referred to as Deathstroke at first but mostly conversed with the one member of the LegionOfDoom who knew him well enough to call him Slade. He was the BigBad of the final arc of ''BewareTheBatman,'' in which there's a battle with the mysterious Deathstroke ''before'' anyone knows what he's all about, but when it's time for him to take center stage as the new main threat, Batman and Alfred learn that Deathstroke and another of his aliases are both Slade Wilson, and from then on he's Slade no matter what he's wearing.
** Inverted with the ''TeenTitans'' themselves. In the comics they refer to each other by name when they're being civilians or aren't in public but the cartoon never has them refer to each other by names. It's implied that they don't even know each others names; the gang are shocked when they learn Beast Boy's name is "Garfield", when they always call him "Gar" in the comics. Cyborg is never called "Victor", although his last name, Stone, is used as an alias in one episode as a MythologyGag. On the other hand, Raven is her actual name, and Starfire is less a pseudonym and more a direct translation. Though she ''is'' referred to as Koriand'r once in a line of Tamaranean dialogue, she's just Starfire to her teammates. Robin's the big one: his name was never said, and there are a [[LegacyCharacter lot of Robins]] out there! In the early days, "Who is Robin?" was considered a RiddleForTheAges. WordOfGod says that he is meant to represent the ''concept'' of Robin rather than any one incarnation. In personality, he's closer to an amalgamation of Dick Grayson and Tim Drake, with the odd bit of Jason's attitude. However, there are plenty of references in the show that make it clear who he must be (It's Dick Grayson's costume, his alternate self is named [[BackwardsName Kcid Nosyarg]], his future self is Nightwing, it's the 80s team lineup, and Starfire sure never was the LoveInterest of any of those ''other'' Robins. The last two or three guys who are still saying "[[WordOfGod Glen Murakami]] didn't ''say'' it's Grayson, so ''every'' bit of Dick Grayson's life being there doesn't mean anything!" aren't taken very seriously anymore.) The tie-in comics finally went ahead and established him as Dick Grayson.
** And it doesn't just go for the main Titans. Every hero and villain we meet already has a codename and is already active by the time we meet them. When the Titans go recruiting, the teen heroes they're scouting are never at school or at home; we find Argent mending a dam, Herald chilling in the other dimension the things he teleports travel through, etc. We never catch anyone on the day of their FreakLabAccident.
* Usually averted in ''WesternAnimation/AvengersEarthsMightiestHeroes'', but Crossfire only gets addressed as "Cross" or "William." Publicity materials refer to him by his codename. [[NotWearingTights Outside of his imagining device, he's not wearing his costume, either.]]
* In ''WesternAnimation/YoungJustice'', Professor Desmond is never actually called "Blockbuster". Instead, Blockbuster is the name of the serum he developed to give him his superhuman strength in the first place.
** Black Beetle is simply referred to as "the Partner" in his first few appearances, including the credits. "Black Beetle" is just a nickname WonderGirl comes up with because [[ExactlyWhatItSaysOnTheTin his armor looks like a black version of]] BlueBeetle's suit.
* In ''WesternAnimation/GIJoeRenegades'', General Hawk is only referred to by his real name, Clayton Abernathy. Likewise, a flashback to Duke's past has Tripwire merely referred to by his real name, Tormod Skoog.
* In ''WesternAnimation/AvengersAssemble'', the Space Phantoms don't refer to themselves as such. Instead, it's just an offhanded name CaptainAmerica gives them since he has no idea what they're ''actually'' called. ComicBook/{{Hawkeye}} even stops to point out how incredibly ridiculous "Space Phantoms" actually sounds.
* In ''WesternAnimation/BatmanTheDarkKnightReturns'', Franchise/{{Superman}} is never referred to as such. He's called "Clark" throughout the entire story, even while in costume.
* Simiar to the examples of Crossfire and Union Jack, Miles Warren in both ''WesternAnimation/SpiderManTheAnimatedSeries'' and ''WesternAnmiation/TheSpectacularSpiderMan'' never went by the codename "Jackal" or wore his costume--but given the latter [[CutShort ended prematurely]], it's entirely possible that he would've at some point had ''Spectacular'' continued.

[[folder: Webcomics]]
* ''Webcomic/CiemWebcomicSeries''
** Candi has to actually tell the reporter that "Ciem" sounds like a good abbreviation for "ciempies." But other than instances where there is no choice but to call her by that name, most characters take pains in the books to avoid ever using the word "Ciem" at all.
** Likewise, Jeral Cormier is only routinely referred to as "Botan the Plant-Man" by the media. Those who know him will almost never use the name; calling him Jeral all the time. Some strangers know him as "Derrick of the Dandelions," and prefer that over calling him Botan.
** After learning about the AI backvisor that was controlling Jeraime, Candi always insists on distinguishing between Jeraime and "Musaran" with the latter referring to the AI.
** Jack has the codename of "Jackrabbit" because of his jumping ability, but has no real way to conceal his identity. So the nickname proves to be useless and everyone calls him Jack anyway.
** Inverted with the Chinese spies, whose real names were not revealed [[AllThereInTheManual until they were published to the wiki in 2011]]. Black Rat, Tin Dragon, Teal Hog, and Stung Hornet are known almost exclusively by their codenames, even to each other. Possibly justified in that they're spies.

!!Notable Aversions:

* Played with in the films. Film/{{Hellboy}}'s real demonic name is not known to him until towards the end of the first movie. He grew up with the name Hellboy and since his other name is tied with the destruction of all mankind and wasn't known until he was about 70, he kept it.
** While on cases, the BPRD paranormal agents usually use names such as "Sparky" and "Blue". His is "Red".
** It should also be noted that in Hellboy, demons have the whole "[[IKnowYourTrueName bound/released by their names]]" deal going on; going around calling himself Anung Un-Rama would be the equivalent of legally changing your name to your social security number.
** His name is mentioned at the end of the second film by Princess Nuala, when her twin brother Nuada questions Hellboy's right to challenge him. Since Hellboy is really demonic royalty, he ''does'' have the right to challenge Nuada.
* In the original Tim Burton/Joel Schumacher ''Franchise/{{Batman}}'' films, [[Film/{{Batman}} The Joker]], [[Film/BatmanReturns Catwoman]], [[Film/BatmanForever The Riddler]] and [[Film/BatmanAndRobin Poison Ivy]] give themselves their names, while the [[Film/BatmanReturns Penguin]], [[Film/BatmanForever Two-Face]] and [[Film/BatmanAndRobin Mr. Freeze]] have had their names given to them sometime before the films begin.
** The Joker names himself as soon as he reveals himself to his first victim - whom he promptly kills. Interestingly, the first time he makes his name known to the public, he uses "Joker" as the name of the brand of (poisoned) beauty products he's advertising on television, never explicitly stating that that's his name as well (at least not until late in the movie, when he hijacks another TV broadcast and announces "Joker here", ironically while disguised by flesh-colored makeup). Nevertheless, that is just what he is soon being called by the media and by all the other characters.
** The name "Catwoman" spreads quickly in ''Batman Returns'', even though Selina Kyle tells only one person that that's her new codename. However, most of the other characters do not call her that, usually only making smart remarks about how she ''looks'' like a cat ([[GettingCrapPastTheRadar "Just the pussy I've been looking for!"]] or offering her "a very big ball of string"). The only exceptions are tabloid newspaper coverage ("I read that Catwoman is supposed to weigh 140 pounds") and one of the Penguin's speeches:
-->'''Penguin:''' I may have saved the Mayor's baby, but I refuse to save a Mayor...who stood by, ''helpless as a baby'', while Gotham was ravaged...by a disease that turned Eagle Scouts into crazed clowns, and happy homemakers into catwomen."
** With The Riddler, there's a scene dedicated to him thinking up a code name for himself. Other names he considered are "The Puzzler" (name of an actual villain from DC Comics), "The Gamester", and "Captain Kill".
** The Penguin in ''Film/BatmanReturns'' goes by both his real name and codename quite frequently. The prominent use of his real name is justified as part of his original plot to murder all of Gotham's first born children; when he reveals himself to the public, he puts on a big show for the media of him "discovering" his real name to be Oswald Cobblepot in order to gain private access to Gotham's public records. This likewise apparently plays into his new VillainWithGoodPublicity ploy to become mayor. When Batman eventually foils his scheme and he suffers his VillainousBreakdown, he's apparently revealed to care nothing for his real name when, in response to a henchman calling him Oswald, he angrily snaps that his name is Penguin.
* Although not based on any specific comic book or manga, ''Film/PacificRim'' is still based on manga/anime properties and notably averts this trope. Directed by Creator/GuillermoDelToro (of ''Film/{{Hellboy}}'' fame, also on this list of aversions), the movie unabashedly embraces the tropes of manga and anime, including giving each and every one of the {{Kaiju}} and [[HumongousMecha Jaegers]] a CodeName.
* The ''UltimateXMen'' comic goes to some trouble to justify ''why'' these kids should have codenames, beyond "because it's a basic trope of the genre". Apparently, these are their "mutant names", as distinct from the "homo sapiens names" their parents gave them.
** This is also touched on during the GrantMorrison run on New X-Men as part of his efforts to give mutants a sub-culture.
* Averted in the ''Film/{{Blade}}'' series. The audience learns that Blade's real name is Eric but it is rarely mentioned.
** Ditto for ''BladeTheSeries''. The only mentions are the flashback episodes to his childhood and when he meets his father, who will not call his only son "Blade".
* Averted with Rorshach in ''ComicBook/{{Watchmen}}'' since no one knows his real identity until the mid-way point. Even then, he prefers the name Rorshach. Other characters oblidge since they never knew him by the name [[spoiler: Walter Kovacs]] anyway. Also, Edward Blake is called by his real name, and his codename, The Comedian, interchanging it scene through scene. All the Minutemen are also called by their codenames only, just Hollis Mason (Nite Owl I) and Sally Jupiter (Silk Spectre I) being given their real names in the film. Nite Owl II and Ozymandias are called mostly by their real names, except on a couple of instances.
* Averted in the GIJoe Films. The Joes and Cobras are referred almost exclusively by their codenames, even in official capacity.
* Averted in ''Film/{{Godzilla 2014}}''. Despite [[http://www.scified.com/site/godzillamovies/igns-godzilla-set-visit-reveals-new-stills-potential-spoilers--godzilla-easter-eggs rumors]] that Franchise/{{Godzilla}} would not be referred to as such in this film, Dr. Serizawa introduces him during the briefing as "Gojira" and the military uses the name Godzilla as a code name for the beast. News broadcasts even dub him "King of the Monsters."
* Ironically, averted in RealLife.
** Decades ago, in order to make news more memorable, rather than use real names, news networks often used nicknames and codenames. Even in more modern eras, this is used when the real name of an individual is unknown or deliberately withheld. For example, "The Unabomber" is a better-known name than "Ted Kaczynski" and "Girl X" is better known than "Shatoya Currie". However, when the real name is known, the news tends to use it, if only to be respectful.
** In sports, most noteworthy players, such as "Orenthal James ("OJ" or "The Juice") Simpson, Michael ("Air") Jordan, or Earvin ("Magic") Johnson. In the latter case, his nickname is ''more'' known than his given name.
** If a writer, musician, artist, etc. achieves fame while using a pseudonym, chances are they'll be far better remembered by that than by their birth name. While sometimes these pseudonyms are outlandish enough to indicate otherwise, there are times when the pseudonym can seem ''less'' outlandish than the person's actual name. Case in point: how many people would guess that Creator/AnneRice's given name is [[GenderBlenderName Howard Allen O'Brien]]?
* Generally averted in ''Arrow'''s spinoff ''[[Series/TheFlash2014 The Flash]]''; mostly because Cisco is the kind of geek that [[TheNicknamer insists on coming up with cool nicknames for everything]]. Most of the others roll their eyes at Cisco's habit but sometimes admit that they've GotMeDoingIt. The Flash himself and Pied Piper also named themselves without Cisco's input, and Captain Cold has officially adopted the name Cisco gave him.
** Roy Bivolo is an odd case, as Cisco names him "Prism", which ''isn't'' used in the comics. It's Caitlin who instead comes up with his comics name, "Rainbow Raider", but Cisco overrules her and "Prism" is the name used in official materials.
** Lampshaded when ''The Flash'' and ''Arrow'' cross over, and Oliver tends to use the codenames as an example of how ''Arrow'' is DarkerAndEdgier while ''The Flash'' is LighterAndSofter:
--->'''Oliver:''' Last month, you took on a man named Leonard Snart--\\
'''Barry:''' We call him Captain Cold.\\
'''Oliver:''' We can talk about you giving your enemies silly codenames later.\\
'''Barry:''' You mean, like, over coffee with Deathstroke and the Huntress?

--->'''Oliver:''' Barry... you live in Central City, where it's sunny all the time and your enemies get cute nicknames. [[WretchedHive You're not in Central City.]]
