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". Contrast with DoNotCallMePaul, which is when calling a character by their true name is forbidden. And {{Kayfabe}} is when it can't even be ''hinted'' that a fantasy character has another identity.

'''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. That isn't to say that the heroes don't have their comic codenames, though they are usually given to the characters by another source, either as propaganda, used as a military call sign, or are dubbed as such by the media.

* ''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 ComicBook/NickFury 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").
** The words "ComicBook/WarMachine" originate in ''Film/IronMan2'' as an offhanded insult from Tony to James Rhodes. Averted by ''3'', where "War Machine" is his official codename and Tony is incredulous that Rhodey actually adopted it just from that remark. Or rather, his ''official'' codename in ''3'' is "Iron Patriot", which Rhodey claims "tested better with focus groups"; but a number of people state they liked "War Machine" better. By ''Avengers: Age of Ultron'', he's just "War Machine" again and uses the name in a BadassBoast.
** 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). The Mandarin is an aversion, being 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.]]
** In ''Avengers: Age of Ultron'', Tony uses a special massive set of armor designed to subdue the Hulk. It's popularly known and marketed as the "Hulkbuster", but the name only shows up in the movie on Tony's HUD - in dialogue, the actual codename for the armor seems to be [[BettyAndVeronica "Veronica"]].
* ''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/{{The Avengers|2012}}'', 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" a.k.a. Emil Blonsky goes by his given name and there is only an offhand reference to that title once, when Dr. Sterns tells Blonksky that augmenting him with the Hulk's blood might turn him into "an abomination". In ''[[Film/MarvelOneShots The Consultant]]'', 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 [[UsefulNotes/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 future movies and shows, it's only done by his codename.
** ComicBook/TheFalcon has his codename used regularly in the various movies he appears in, adopted from the model of flight pack he uses.
** Technically, this trope is true of Montgomery Falsworth, aka "Union Jack", in the first movie. 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'': The "Winter Soldier" codename is invoked frequently, but the heroes stop calling him this once they find out that he is [[spoiler:ComicBook/BuckyBarnes]]. In ''Civil War'' it's explained that [[spoiler:there are more HYDRA super-assassins, and Bucky refers to them as "Winter Soldiers" as well]]. Georges Batroc is revised to be a normal mercenary instead of a supervillainous one and is never called "Batroc the Leaper". 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; in ''Civil War'' she only goes by her given name (and may in fact have lost her "Agent" designation after [[spoiler:S.H.I.E.L.D. fell]]).
** ''Film/CaptainAmericaCivilWar'': Brock Rumlow is never referred to as Crossbones, though a tie-in comic establishes that the codename does exist in-universe (it also wasn't used when the character was in ''Winter Soldier'', but at that point he hadn't taken the identity of Crossbones yet). Zemo never had a codename to begin with, but is nonetheless changed from ''Baron'' Zemo since he's a Sokovian soldier rather than an German aristocrat as he is in the comics.
* From multiple movies, Natasha Romanov's handle of "Comicbook/BlackWidow" never comes up in ''Iron Man 2'', and is only used in ''The Avengers'' 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 an agent refers to her as Black Widow while communicating with Rumlow. The name was absent from ''Avengers: Age of Ultron'', but reappeared in ''Civil War'' when Zemo mentions "the Black Widow."
* In ''The Avengers'', 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, and in ''Avengers: Age of Ultron'' it's used once in an affectionately mocking way by [[spoiler:his wife]]. It's absent again in ''Civil War'', and when meeting Black Panther he explicitly introduces himself as "Clint", not "Hawkeye".
* 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'': Most characters don't go by codenames, though a reference is often snuck in somewhere:
** 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".
** Lampshaded aversion: 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 he's embraced it; which is then 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 -- in the comics it was called the Overkill ''Horn''. (Since it uses sound waves)
** Averted again with the first season BigBad, who 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 on 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:''' Because [[SarcasmMode nothing bad ever happens]] when you're working with [[NamesToRunAwayFromReallyFast something called "Darkforce."]]
*** Darkforce and its other name from ''Agent Carter'', "Zero Matter", get referenced in a later season, prompting another round of snark:
--->'''Mack:''' Who names these? Are there focus groups for evil things?
** Other villains that don't have their codenames used include Carl Creel (the Absorbing Man, though it is referenced in dialogue), Daniel Whitehall (Kraken), Marcus Scarlotti (Whiplash, likely because it was already taken by Vanko in ''Iron Man 2''), and David Angar (Angar the Screamer). The same goes for one of the heroes, Bobbi Morse (ComicBook/{{Mockingbird}}).
** Inverted with one of Whitehall's [[TheDragon Dragons]], Agent 33, who had suffered a LossOfIdentity thanks to {{Brainwashing}} and whose name ([[spoiler:Kara Palamas]]) was not known, even to her, until she started getting it back.
** The real names of Skye and her father (originally credited as "the Doctor") 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 names were revealed to be ComicBook/{{Daisy|Johnson}} and Cal Johnson respectively, known in the comics as "Quake" and "Mister Hyde" (real name Calvin ''Zabo''). Cal's codename wound up never being used during his time on the show, but he implied that it existed (he mentioned that he changed his surname, though he didn't specify whether it was to "Zabo" or "Hyde"). Skye eventually switched to using "Daisy Johnson" full-time, while the name "Quake" didn't appear until another season and a half after the reveal, when [[spoiler:Daisy became a vigilante and the media caught wind of her]].
** CanonForeigner Lincoln Campbell was assigned the codename "Sparkplug" by SHIELD, but it has never been used in the show and barely shows up in promotional material either.
** Averted with Lash for similar reasons as the Clairvoyant; to preserve the mystery of his real name. After TheReveal, it's still used [[spoiler:to differentiate his human identity from his [[WithGreatPowerComesGreatInsanity less rational superpowered side]].]]
** The Season Three BigBad is known in the comics as Hive (as in MindHive). In the show, it took most of the season to reveal that in ancient times it was known as "Alveus" (Latin for "Hive"), but once that's known the English translation caught on quickly. Up until then, the closest thing it had to a name was [[NothingIsScarier "It"]].
** Defied with James in Season Three. As soon as he gets [[PlayingWithFire heat and explosion]] powers, he starts brainstorming fire-related codenames to use before he settles on his comics name of "Hellfire".
** Played with for Elena Rodriguez. In the comics, she's ''Yolanda'' Rodriguez, with the nickname of "Yo-Yo" but the official codename of "Slingshot". In the show, she still gets the nickname "Yo-Yo" despite the fact that it no longer links to her given name, but "Slingshot" is never used... until a series of web videos starring her came out, bearing the title ''WebVideo/AgentsOfSHIELDSlingshot''. Even then, "Slingshot" still isn't used in-universe.
** The results of an imperfect attempt to create Inhumans are dubbed "Primitives". In the comics, these are the ''Alpha'' Primitives, the Inhumans' slave race. The "alpha" part gets a nod when their creator says they're just an alpha version and begs his boss to let him make improvements for a beta test.
** Averted with [[ComicBook/AllNewGhostRider Ghost Rider]], who is introduced as having already started to become an urban legend under that name in LA.
** Jeffrey Mace doesn't use the codename "Patriot", but is referred to as a patriot a few times in dialogue. [[spoiler:And the serum that gives him his powers is also called "Project Patriot".]] He's also compared to Captain America in-universe, referencing how he held that title in the comics for a while as Rogers' successor.
* ''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, 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''.
** One character is formally introduced, both here and in TheStinger of ''Thor: The Dark World'', as "Taneleer Tivan, the Collector", covering both real name and "codename" in one fell swoop.
** 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 Season One's 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; her given name is explicitly an alias) and is only identifiable by sharing a backstory with [[spoiler:Natasha Romanoff]]. 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.
** In Season Two, Whitney Frost doesn't go by her codename Madame Masque; there are some visual references made to it but as Whitney never actually wears a mask, the name wouldn't make sense if it were used. Joseph Manfredi also doesn't go by "Blackwing", though it's another case where this version isn't a supervillain and so has no need for a codename. The conspiracy of powerbrokers has been renamed from the Secret Empire to the Council of Nine or just "the Council". Finally, the season's {{Phlebotinum}} is called Zero Matter instead of Darkforce, though Wilkes calls it ''a'' "dark force" (and ''Agents of S.H.I.E.L.D.'' had already established that it will be called Darkforce by modern times).
* ''Series/Daredevil2015'':
** Daredevil starts out as just "the man in the black mask". After the bombings of the Russian hideouts and the cops getting shot, Wilson Fisk paints him as a terrorist and the media dub him "the Devil of Hell's Kitchen". It's only at the end of the season when he's proven himself a hero by stopping Fisk's escape attempt, that he becomes "Daredevil". Matt Murdock and his friends make fun of but admit is better than the last name. However, the "Daredevil" name is not used that often in season 2 as people still are more used to his more dramatic "Devil of Hell's Kitchen" alias.
** Wilson Fisk is never called "Comicbook/TheKingpin" once in the first season, but he does receives a few references to kings (examples: on Ben Urich's corkboard, Fisk is represented by a ''King'' of Hearts playing card affixed by a white push''pin'', Detective Blake calls him "King Frickin' Kong"). It eventually comes into play in season 2 while he's in prison. Dutton, an inmate who runs the prison's underground economy, [[BullyingADragon tries to intimidate Fisk by claiming he's the kingpin of the joint.]] Fisk, of course, arranges his death at the hands of the Punisher, and then, as Dutton lies dying on a hospital bed, tells him, "In prison, there's only room for one kingpin," and officially takes the nickname for himself. Even then, the nickname doesn't really catch on, as whenever Fisk gets mentioned in ''Series/LukeCage2016'', it's only by his real name.
** In the second season, Frank Castle's alias as "ComicBook/ThePunisher" starts out as a codename the NYPD used while trying to figure out who the guy was, and the media popularize it from there.
** In [[http://collider.com/daredevil-season-2-deborah-ann-woll-elden-henson-interview/ a January 2016 interview]], Creator/DeborahAnnWoll (Karen Page) commented that she more often than not has a habit of referring to Fisk and Castle by their pedestrian names more often than their villain names, and posits that the non-usage of their codenames establishes these characters as complex people who gradually evolve into the persona of their codename.
** Many of Wilson Fisk's henchmen have codenames in the comics, like Leland Owlsley (The Owl), John Healy (Tenpin [[CompositeCharacter and/or]] Oddball), Roscoe Sweeney (The Fixer), Melvin Potter (Gladiator), and Ben Donovan (Big Ben). Obviously, these are just normal people and not costumed supervillains. There are a few nods to the names, but not many: Healy kills a victim with a bowling ball, Melvin has some Roman gladiator posters on his workshop wall and in season 2 offers to show off his Gladiator suit, Roscoe Sweeney is ''a'' fixer of boxing matches, Owlsley is shown getting a business suit tailored that looks like his comics suit, etc.
** Season 2 has a rare inversion, assigning a codename to someone that didn't have it before. Part of the plot involves tracking down a mysterious drug lord, called "the Blacksmith" because nobody knows his real identity. The character existed in the ''Punisher'' comics, and like the show was a drug dealer and [[spoiler:Frank's former commanding officer Ray Schoonover]], but didn't have a codename.
* Shared among the various Netflix shows, the Chitauri invasion from ''The Avengers'' is simply known as "The Incident". The early script drafts for ''Daredevil'' were originally going to refer to it more directly, but it was found that the words "AlienInvasion" killed the mood the series was going for. As time goes on, the shows are more willing to directly refer to the attack and use the word "alien", especially in ''Series/JessicaJones2015'' and ''Series/LukeCage2016''.
** Another cross-show example is Claire Temple, a CompositeCharacter with the comics character codenamed "Night Nurse". In five seasons across four shows so far, the codename has only been mentioned once when a gangster referred to her as such in ''Luke Cage''.
* ''Film/AvengersAgeOfUltron'':
** Averted with ComicBook/{{Ultron}} and ComicBook/TheVision, who have no other names. Vision was originally referred to as a metaphorical vision of various characters', but later, Tony, and eventually Steve and Thor use it by the end of the movie, all in a way that indicates it's been adopted as his official name.
** Wanda and Pietro Maximoff are never referred to as ComicBook/ScarletWitch and ComicBook/{{Quicksilver}} by way of WritingAroundTrademarks[[note]]due to the cinematic rights to the mutant characters being owned by 20th Century Fox, whose X-films have actually introduced their ''own'' Quicksilver[[/note]]. The closest is when Tony refers to Wanda as "that little witch".
*** Parodied by ''WebVideo/HonestTrailers'':
-->...The Avengers roster bloats even further with '''Vision''', '''Scarlet Witch''' and '''Quicksilver''', who for some reason, are never called '''Vision''', '''Scarlet Witch''' or '''Quicksilver.'''
* ''Film/AntMan:'' The "ComicBook/AntMan" moniker is used by SHIELD (in its anti-Soviet propaganda films) to refer to Hank Pym. The latter then passes the title (along with the corresponding powered suit) to Scott Lang. Hank also explicitly refers to his wife Janet van Dyne as "ComicBook/TheWasp". "Yellowjacket" is the name for the new powered suit Darren Cross develops rather than a specific person's nickname, although he is the only person to use this technology in the movie.
** In ''Civil War'', Scott [[spoiler:uses his powers to grow to AttackOfTheFiftyFootWhatever size for the first time]], but none of the related codenames like [[spoiler:"Giant-Man" or "Goliath"]] are mentioned.
* ''Series/JessicaJones2015'':
** Jessica Jones and Luke Cage (below) hardly had them in the comics to begin with. In a flashback, Trish encourages Jessica to take up superheroics, suggesting she use the nickname "Jewel" (the codename in her comic backstory). Jessica shoots the idea down and says "Jewel is a stripper's name, a really slutty stripper. And if I wear that thing, you're gonna have to call me Cameltoe."
** Trish Walker ([[ComicBook/PatsyWalker Hellcat]]) and Will Simpson (Nuke) don't get their codenames referenced either. Given Simpson's first name was changed for the series[[note]]He's Frank Simpson in the comics. His first name was changed so as [[OneSteveLimit to avoid confusion with Frank Castle]], who was being introduced in season 2 of ''Series/Daredevil2015''[[/note]], it isn't immediately apparent that he's Nuke, right down to the pills that give him super powers, until he utters his (in)famous catchphrase of demanding "Reds."
%%** Not even established superheroes like the Avengers have their names stated when they're mentioned, instead being "the flag-waver" or "the big green guy".
** Played with for Kilgrave. In the comics he's "[[http://en.wikipedia.org/wiki/Purple_Man The Purple Man]]", real name Zebediah Killgrave. In the show, he's simply "Kilgrave", and characters ''still'' [[RunningGag mock it as sounding like a blatant]] [[NamesToRunAwayFromReallyFast scary name]], the kind of name a kid would come up with to sound threatening but is actually ridiculous. [[spoiler:It turns out that "Kilgrave" is an alias. His real name is Kevin Thompson, and he really ''is'' [[PsychopathicManchild that childish]].]] While he's never referred to as the "Purple Man" on screen, the name is still alluded to: most of his wardrobe is comprised of purple clothing, a purple tint is applied to a number of his scenes, and people affected by his mind control see the world covered in purple light. In the finale, he does start turning purple after getting a power boost, but even that is more subtle than the deep shade of his comic book version. He also starts turning purple as Jessica chokes him and breaks his neck.
* ''Series/LukeCage2016'':
** ComicBook/{{Luke|CageHeroForHire}} himself and ComicBook/MistyKnight barely have codenames in the first place. Luke does have an infrequently-used name of "Power Man" in the comics, which is shown here as one of Pop's {{Affectionate Nickname}}s for him.
** In a clever aversion, the codenames used by criminals, such as Shades (real name Hernan Alvarez) and Diamondback (real name Willis Stryker), are repurposed as street gang nicknames.
** Played with for Cottonmouth. In the comics, it was [[StevenUlyssesPerhero his real surname]]. Here, his name is Cornell ''Stokes''. [[BerserkButton And he absolutely hates being called]] [[EmbarrassingNickname "Cottonmouth"]].
** Mariah Dillard doesn't go by "Black Mariah". Cottonmouth taunts her with that name once, and it [[BerserkButton sets her off]].
* ''Film/DoctorStrange2016'' is another case where nobody has codenames to begin with. Yes, even our hero himself, who is legally [[StevenUlyssesPerhero Stephen Strange, MD]]. Like the Zemo example above, Baron Mordo is not actually a Baron here and is just called Karl Mordo.
* ''Series/IronFist2017'': Averted for Iron Fist himself, as the name is a proper title. While ComicBook/ColleenWing doesn't have her own codename in the comics, she does make a reference by calling herself "Daughter of the Dragon" in underground cage matches; which is the team name for [[ComicBook/DaughtersOfTheDragon her and Misty Knight as a duo]].
* ''Film/SpiderManHomecoming'': Spider-Man averted it early on, as in his debut appearance in ''Civil War'', Peter and Tony openly discuss his codename. ("You're, what? Spider-ling? Spider-Boy?" "...Spider-Man." "Not in that onesie.")
* ''Film/BlackPanther'': When the character is introduced in ''Civil War'', T'Challa mentions the name to explain why his costume is cat-themed, but it's otherwise unused. Even so, its existence is justified since it's not merely a codename but a tribal and royal title. In ''Age of Ultron'', ''Panther'' villain Ulysses Klaw appears under his original surname of ''Klaue'', instead of his supervillain name.

[[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 "[[Film/XMenFirstClass 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, a few 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 generally used as {{Mythology Gag}}s or {{Futureshadowing}}, and occasionally to differentiate between a person's "regular" self and his/her superhero/supervillain persona.
** [[Characters/XMenFilmSeriesWolverine 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 Myth/{{Native American|Mythology}} folk-tale his girlfriend recounts to him.
** The code name [[Characters/XMenFilmSeriesProfessorCharlesXavier Professor X]] is only used twice in both ''Film/XMenFirstClass'' and the ''Film/XMenFilmSeries'', and Xavier brushes it off. He's more commonly addressed by his professor title, or Charles by those who are close to him.
** [[Characters/XMenFilmSeriesMagneto Magneto]] is often referred to as Erik, although usually only by Xavier, Mystique, and Beast.
** [[Characters/XMenFilmSeriesMystique Mystique]] is frequently called Raven by Charles and Hank.
** Comicbook/{{Cyclops}}' codename is mentioned, but he mostly goes by Scott throughout all of the movies.
** Comicbook/JeanGrey and Comicbook/KittyPryde never use codenames in the films. While their comic counterparts went through a few over the years, they usually go by their birth names anyway (a rarity for superhero comics).
** Hank [=McCoy=] doesn't go by his codename Beast in ''Film/XMenTheLastStand''. He does eventually embrace the nickname that Havok bestows on him just before the climax of ''First Class'', however. In ''Film/XMenDaysOfFuturePast'', Wolverine calls Hank (who has essentially retired from superheroics due to the X-Men having disbanded) Beast and "Beastie" several times to try and goad him into a fight. He's most often referred to by his given name, though.
** Storm is the lone aversion. She's almost always called by her code name in the films. The only time her real name Ororo is used is when Xavier introduces her to Wolverine, or when Beast greets her in the third film.
** [[Characters/XMenFilmSeriesDeadpool Deadpool]] is never referred to as "Deadpool" in ''Film/XMenOriginsWolverine'', and is always called "Wade" or after his transformation "Weapon XI." The closest they ever get is Stryker calling the experimental procedure "The Deadpool." This is averted in his [[Film/{{Deadpool 2016}} solo film]] where he is referred to as such rather frequently.
** 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. He does go by Colossus in ''Film/{{Deadpool 2016}}'', along with the other X-Mansion resident that shows up, [[AwesomeMcCoolName Negasonic Teenage Warhead]].
** The name Nightcrawler is only mentioned in ''Film/X2XMenUnited'' when Kurt expounds about his time at the Munich circus. In ''Film/XMenApocalypse'', he is introduced in a cage fight as Nightcrawler, corrects Mystique when she calls him "Crawler," and Jean says his codename when she orders the X-Men to "grab hold of Nightcrawler," but mostly goes by Kurt.
** ComicBook/{{Quicksilver}} is never called by that name in ''Film/XMenDaysOfFuturePast'' and ''Film/XMenApocalypse''. He's known simply as Peter.
** Havok is said only once in ''Film/XMenFirstClass'', it's alluded to when Professor Xavier orders him to "Wreak havoc" in ''Film/XMenApocalypse'', but the name is only used once in this film when Mystique recounts their first mission. The rest of the time, he's just Alex.
** Warren Worthington III's codename Angel is never used in ''Film/XMenTheLastStand'', but he gets a big subversion in ''Apocalypse'', being referred to only as "Angel."
** ''Film/X2XMenUnited'': Lady Deathstrike is never used. Her real name (Yuriko) is only mentioned in passing.
** ''Film/XMenTheLastStand'': Subverted and played straight with Jimmy 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.
** ''Film/XMenOriginsWolverine''
*** Comicbook/{{Sabretooth}} is only called "Victor" throughout ''Film/XMenOriginsWolverine''.
*** 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, although it's stated to be a prison nickname he was given by Stryker's guards.
** ''Film/XMenFirstClass'':
*** 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 Salvadore (not to be confused with Warren Worthington III's Angel); 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.
** ''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. For legal reasons, her other moniker "Madame Hydra" does not come up, due to Marvel owning the rights for {{ComicBook/HYDRA}}.
*** 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 Free Mutants 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.
** ''Film/{{Deadpool|2016}}'': It's a plot point that villain Ajax is actually Francis, with the title character only calling him by the given name to mock Ajax afterwards. Subverted with his henchwoman Angel (Angel Dust in the comics), who never gets a proper name. Just for fun, Deadpool introduces himself to the taxi driver Dopinder as "[[TheNameIsBondJamesBond Pool, Dead]]." After that, Dopinder consistently refers to him as "Mr. Pool" and even adds him as a contact on his phone this way.
** ''Film/XMenApocalypse'':
*** [[Comicbook/{{Apocalypse}} The title villain]] is never called by anything other than given name En Sabah Nur, although there's a MythologyGag to [[NamesToRunAwayFromReallyFast the name he adopted in the comics]] ("Where ever this being was, he would always have four followers who he would imbue with power." "Like the Four HorsemenOfTheApocalypse.").
*** Subverted by Comicbook/{{Psylocke}}, who is only called by her codename.

[[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."]]
* 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. (This was also true in the 1989 film, when Batman tersely refers to the Batmobile as simply "the car"; the more famous title wasn't used until ''BatmanReturns'' three years later.) 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:(Non-MCU) 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 ComicBook/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.
** In the novelization, the name is at least alluded to when Eddie taunts Spider-Man by saying that they are (in reference to himself in the symbiote) his "venom".
* 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:DC Extended Universe]]
** 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.
*** After averted. By ''Film/BatmanVSupermanDawnOfJustice'', Clark/Kal-El's superheroic alter-ego is commonly referred to as Superman; this continues in ''Film/SuicideSquad2016'' where the name is casually mentioned in discussions.
** On the other hand, the film also features Anatoli Knyazev. who's never called [=KGBeast=], {{Justified|Trope}}. as The KGB has been disbanded a long time ago.
** When Diana suits up in the finale to battle Doomsday alongside Bruce and Clark, she's never given a codename. and is only referred to as Wonder Woman in the credits.
** Likewise, Bruce is only actually called "Batman" once. when Perry [[LeaningOnTheFourthWall says that nobody would be interested in Clark Kent fighting the Batman]], the other times it's some variation of "the Bat" to refer to him.
** The creature is never called "Doomsday," though Comicbook/LexLuthor uses the term when describing its role.

[[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 Doctor Doom (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, "DoctorDoom" 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".
** In the [[Film/FantasticFour2015 2015 reboot]], Sue jokingly calls Doom "Doctor Doom". It also completely avoids any kind of codenames for the heroes until the very end, when Reed starts brainstorming names for the team and Johnny jokingly suggests "The Human Torch and the Torchettes" and "Two Guys, a Girl, and The Thing Nobody Wanted." Reed eventually gets an idea when he hears the word "fantastic", but then the movie cuts to the end credits before he actually says it.
** This is true to the comics as they rarely use the code names with each other, since they are public figures. Reed, especially, is more know for his scientific accomplishments. Ben and Johnny are more likely to use them in public since they are more outgoing and are more likely to cater to "fans". Ben will call HIMSELF "The Ever Lovin' Blue Eye Thing", but other heroes rarely do.
* ''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/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."
* In ''WesternAnimation/ThorTalesOfAsgard'', Valkyrie is simply called Brunhilde, though her group of female warriors are collectively known as the Valkyries.
* ''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 Lift}}s (they go from Japanese to Latina and Korean-American), 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]].
** The team is never called "Big Hero 6" in the movie. However during the closing credits, a news website headline reads "Big Hero 6 Saves Orphanage".
* ''Anime/AvengersConfidentialBlackWidowAndPunisher'' never sees Elihas Starr called "Egghead".
* In ''Film/BatmanAndRobin'' never sees Jason Woodrue called "the Floronic Man". Though, we never see him go "Floronic" in the first place.

* 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 ComicBook/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 ''ComicBook/{{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/TheKillingJoke'' never has Batman or Joker referred to by their codenames; they are always referred to by some other descriptor, such as "bat-themed vigilante", and the closest to their actual names is when "Joker" appears partially obscured on the Batcomputer.
* ''ComicBook/SecretSix'': Catman simply goes by his civilian identity of Thomas Blake.
* Very briefly during the ''ComicBook/{{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 ''Literature/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 ''ComicBook/{{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, 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 ComicBook/LexLuthor "Luthor".
* ComicBook/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.

* The Literature/{{Animorphs}} were rarely referred to as that within the books, except by Marco ([[TheNicknamer who coined the name]]); this was partially because most of their enemies thought them to be Andalites, not humans (hence referring to them as "Andalite bandits"). They did start using it more frequently towards the end, though (and it was also used quite a bit in the [[Series/{{Animorphs}} TV series]], too).

[[folder:Live Action TV]]
* In ''Series/{{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. ComicBook/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]] is generally referred to as "Unidentified Lifeform #4" (or just "Number 4" for short), thanks to the police mistakenly thinking he's one of the Grongi at first[[note]]They also mistake his weak default form as an entirely different being, "Unidentified Lifeform #2"[[/note]]. Only a few people know his proper name is 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 mistaken for a returning Kuuga/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''. This series advances the idea that Kamen Riders are UrbanLegends, with supporting cast member Kotaro Shirai trying to research them for a book he wants to write, which leads to his befriending Kazuma Kenzaki (Blade). However, it's (perhaps intentionally) hard to tell if he means '''all''' the Kamen Riders or just the ones from this specific series, who were active for a little while before the series begins. On top of that, the belts are actively called "Rider Systems" by their creators, and the term "Kamen Rider" is used many times throughout the show.
** [[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.''
** Unsurprisingly averted in ''Series/KamenRiderDecade'', being an anniversary season featuring every Rider at that point. Decade even refers to himself as "just a passing-by Kamen Rider"
** Averted in ''Series/KamenRiderDouble,'' where the people of Fuuto give the name "Kamen Rider" to their mysterious protector. Shotaro, who's very fond of the city, takes a good deal of pride in the name, and when a MonsterOfTheWeek tries to frame them he almost seems angrier at his sullying the "Kamen Rider" name. However, only people in the know refer to him as "Double".
** 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. And of course all this is ignoring the Fourth Wall-shattering MilestoneCelebration of the franchise's 999th and 1000th overall episodes, which openly refer to ''Kamen Rider'' '''as''' a franchise, with a retired {{Mook}} who has a notebook listing the names, episodes, and airdates of every monster the Riders ever defeated.
** In ''Series/KamenRiderFourze''[='s=] second episode, PerkyGoth Tomoko sees Fourze defeat the MonsterOfTheWeek and refers to him as a Kamen Rider, explaining that they're considered an Urban Legend by the world at large, but she has proof of their existence (security camera footage of several past Rider battles). Gentaro proudly adopts the name and does his best to live up to their reputation, including seeking out past Riders' approval (and friendship) in crossovers.
** ''Series/KamenRiderWizard'' plays by the rules of the early 2000s' series, not using the term "Kamen Rider" outside of crossovers. Outsiders refer to the heroes as "wizards" (''mahoutsukai'') rather than Riders, while people who know them personally use their GratuitousEnglish titles like "Wizard" and "Beast". However, one such character (the White Wizard) is ''only'' referred to by this nickname; his "Rider name" wasn't revealed until after the series had ended, and since the name would have been a massive spoiler the use of a nickname was wholly justified. [[spoiler:The name is "Kamen Rider Wiseman", which reveals that the White Wizard and the villains' leader Wiseman are one and the same]].
*** 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 due to his 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 in fact 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 Roidmudes coined it in the backstory to refer to the original Drive as something of a [[TheDreaded Dreaded]] nickname; when the new Drive pops up, the Roidmude's reaction is "OhCrap ''Another'' one of you Kamen Riders?!", making it the first time both Drive himself and the audience hear the term. Funnily enough, this is the series where "Kamen Rider" is an ArtifactTitle, since Drive is the only hero in the franchise who uses a CoolCar instead of a CoolBike.[[note]]One Rider, Series/KamenRiderBlackRX, had one of each.[[/note]]
*** This also allowed the staff to play around with the advertising campaign, by announcing "This Rider is a driver!" When they introduced the SecondRider Mach (who actually does have a motorcycle), they spoofed themselves by declaring "[[DepartmentOfRedundancyDepartment This Rider is a rider!]]"
** ''Series/KamenRiderGhost'' goes back to generally not using the title (except for the OpeningNarration). Oddly, it is established to exist in-universe as Ghost is given the "Kamen Rider" title by the sage who gives him his powers; but unlike in other Rider series no reason is ever provided as to ''why'' the sage would name him that.
** Averted in ''Series/KamenRiderExAid'', which uses a similar system as ''Blade'' and ''Kabuto'' in that there's an organization recruiting and equipping people to fight the monsters, and they're the ones designating such people as Kamen Riders.
** ''Series/KamenRiderAmazons'' plays this straight for the Kamen Rider name, as it appears to take place in a world with no previous Riders at all. Furthermore, the main Riders are never referred to as Amazon Alpha or Amazon Omega, instead using their names or "the red/green Amazon" (the Amazons being the monsters of the series), despite their transformation belts calling out "Alpha" or "Omega". The third Rider, Kamen Rider Amazon Sigma, is indeed called "Amazon Sigma" once to differentiate him from [[spoiler:Jun Maehara, the dead body he posesses]], although the Kamen Rider name is still never used.
** 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 ComicBook/GreenArrow:
** That name isn't used until halfway through the first season, when ''Merlyn'' [[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's not until season four that he starts calling himself the 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 Malcolm Merlyn. In the comics "Merlyn the Archer" is a code name he chose due to his obsession with Arthurian myth, in the series it's his real name, while the nickname given to him by the SCPD is "the Dark Archer", or, alternatively, "the Copycat".
*** Additionally, Merlyn's real name from the New Earth comics, Arthur King, appears in ''Arrow'' tie-in ''Dark Archer'' comics, where it's mentioned as his actual birth name. He legally changed from "Arthur King" to "Malcolm Merlyn" to evade a whole different shadowy group going after him.
*** However, his League of Assassins name, "The Magician", is used fairly regularly by League members and others in the know. Ironically, he got the name from a young Nyssa Al'Ghul for doing a stage magic trick (pulling a flower from nowhere) rather then as a play on his own name.
*** Additionally, in the current Prime Earth comics, Tommy Merlyn plays the role of Green Arrow's rival, going by simply "Merlyn" as a mercenary. On ''Arrow'', Tommy never becomes the Dark Archer.
** Barton Mathis is referred to as Dollmaker, and is justified in this case. In the show, he's a flat out serial killer, 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. Later on, [[spoiler: Laurel Lance, her sister, takes up the mantle after Sara's death, and was called the Black Canary]].
** Bronze Tiger also breaks the rule.
** Anatoli Knyazev is never called the "[=KGBeast=]".
* ''Series/{{Gotham}}'':
** The series 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," though he's not yet a villain, just a GCPD lab rat who likes to spout riddles at people.
** As Cobblepot's star rises within the Gotham mob, he grows more fond of his nickname, even insisting on "''[[SpellMyNameWithAThe The]]'' Penguin" when a henchman drops the article.
** This is likewise played with, with more minor or new villains, some are called by their codename more than their real one. The Balloon man, The Electrocutioner, The Ogre, and notably the Dollmaker (whose real name is only mentioned once by himself). Others don't have a code name, and some are ownly known by their codename (such as Copperhead).
* Usually averted in the 1966-1968 ''Series/{{Batman}}'' TV series, but on occasion the more serious villains would have their true names mentioned, such as Batman referring to Mr. Freeze as "Dr. Shivel" in Freeze's very first episode (the "Victor Fries" name did not yet exist). There were also a few more ordinary villains who went by their birth names, or at least by names that ''sounded'' like they could be real, such as "Nora Clavicle", a crooked female politician. And there were more subtle examples: Commissioner Gordon was never once called "James" or "Jim"; of course, considering what a stuffed shirt this incarnation was compared to other portrayals, [[DoNotCallMePaul he probably wouldn't have appreciated anything other than "Commissioner]]."
* ''Series/PrettyGuardianSailorMoon'' plays with it. In contrast to the anime where the girls made a point of addressing each other by codenames when transformed, they're more likely to call each other by their real names. They're only ever called 'Sailor X' when they themselves are delivering their InTheNameOfTheMoon speech, when someone is talking ''about'' them or from people who don't know their civilian names. And often they'll drop the 'Sailor' part and refer to the respective girl by her planet's name instead.
* ''Series/{{Supergirl 2015}}'' mostly averts this, but in the episode [[Recap/Supergirl2015S2E7TheDarkestPlace "The Darkest Place"]], VillainOfTheWeek Philip Karnowsky is never referred to as "Barrage", his codename from the comics.

[[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 [[Film/HellboyIITheGoldenArmy 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:Video Games]]
* Outside of his bios in ''VideoGame/BatmanArkhamAsylum'', ''[[VideoGame/BatmanArkhamCity Arkham City]]'', and ''[[VideoGame/BatmanArkhamKnight Arkham Knight]]'', the ''VideoGame/BatmanArkhamSeries'' version of Hush is never referred to by that name, but rather "the Identity Thief" or his real name of Tommy Elliot.

[[folder: Western Animation]]
* Franchise/{{DCU}}:
** 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 ComicBook/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, Creator/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 ''WEsternAnimation/YoungJustice: Invasion,'' 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.
*** Part of this is due his using the HeelFaceRevolvingDoor. He was pretty much a good guy and ally once his original Titans storyline ended and he'd always been a little picky about his mercenary work even before that.
** Inverted with the ''WesternAnimation/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 was primarily Dick's LoveInterest. 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/TheAvengersEarthsMightiestHeroes'', 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 ComicBook/WonderGirl comes up with because [[ExactlyWhatItSaysOnTheTin his armor looks like a black version of]] ComicBook/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. Similarly, Dr. Archibald Monev doesn't use the codename Doctor Venom.
* In ''WesternAnimation/AvengersAssemble'', the Space Phantoms don't refer to themselves as such. Instead, it's just an offhanded name ComicBook/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.
* Similar 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.
* Daedalus Boch is never referred to as "Doodlebug" in ''WesternAnimation/BewareTheBatman''.

[[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 [[Film/HellboyIITheGoldenArmy 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 ''ComicBook/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 Creator/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 [[Series/{{Blade}} the TV series]]. 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, partly because no one outside the government knew he was The Comedian until after he died. 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 to exclusively by their codenames.
* 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.
** Also averted in sports, with some noteworthy players having nicknames more famous than their real names. Examples include "Orenthal James ("OJ" or "The Juice") Simpson, Earvin ("Magic") Johnson, or Edward [[PropheticNames ("Fireball")]] Roberts.
** 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]]? Or that Creator/MarkTwain wasn't actually named Mark Twain (but Samuel Langhorne Clemens).
* Generally averted in ''Arrow'''s spinoff ''Series/TheFlash2014''; 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. Captain Cold in particular seems to enjoy having a supervillain name and encourages its use (though he tends to drop the "Captain" more often than not).
** Played with in the case of Weather Wizard. The premiere episode featured Clyde Mardon (brother of Mark Mardon, the comics' Weather Wizard) as the apparent adaptation of the character, but Cisco never gave him a name and he was a StarterVillain that was quickly killed off. Later in the season, Mark himself showed up with the same powers, and by having Cisco give him the name the show has recognized Mark as the "official" Weather Wizard.
** 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 tells her something to the effect of "see, this is why we don't let you come up with the names." "Prism" is the name used in the show and other official materials from then on, though "Rainbow Raider" still gets the occasional nod.
** [[spoiler: Earth-2]] Hunter Zolomon plays with this. He is generally referred to as Zoom, but he is never called [[spoiler: the Black Flash]] after becoming it.
** 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:''' The ''point'' is...

--->'''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.]]
* While played straight with the ''WesternAnimation/GIJoeRenegades'' versions of Dr. Venom, General Hawk, and Tripwire, the rest of the character is ''Renegades'' generally averted it in three ways.
** The first being many characters including Duke, Flint, Lady Jaye, Heavy Duty, Snake Eyes, Stalker (shown in the same flashback as Tripwire, though [[AdaptationNameChange modified to Stalker One]]), Shipwreck, Snow Job, Frost Bite, Wild Bill, Lift-Ticket, Red Star, Steeler, Jinx, and most of Cobra's other agents already had theirs before the series.
** The second is many other characters including Scarlett, Roadblock, Tunnel Rat, Ripcord, Destro, Breaker, Airtight, and Barbecue gain theirs over the course of the series.
** Thirdly, a few characters who don't outside of Tripwire and General Hawk aren't in the military: While this wouldn't affect Carl Greer as "Doc" is commonly used as a short version of "doctor", anyway, it does mean Courtney Kreiger, Christopher Lavigne, and Vince Hauser aren't respectively called "Cover Girl", "Law", and "Lt. Falcon".
* ''[[Film/{{Deadpool2016}} Deadpool]]'' uses codenames more than the character's real names. Negasonic Teenage Warhead, a relatively minor X-Men character, got promoted to one of Deadpool's partners simply because the writers really liked her codename and wanted to defy this trope as much as possible. The one exception is [[BigBad Ajax]], whom Deadpool insists on calling by his real name of Francis just to annoy him.
* This is played with in the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012]] adaptation of [[Franchise/TeenageMutantNinjaTurtles Teenage Mutant Ninja Turtles]] with Mikey being the one who gives the codenames.
** Played with by Rocksteady who always prefers his code name but the Shredder always calls him by his real name.
** Bebop prefers to use his real name and hates being called Bebop.
** Rahzar always gets called by his real name by most of the Foot Clan.
