History ComicBookMoviesDontUseCodenames / XMenFilmSeries

* Comicbook/{{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 codename Comicbook/ProfessorX is only used twice in both ''Film/XMenFirstClass'' and the first ''[[Film/XMen1 X-Men]]'', and Xavier brushes it off. He's more commonly addressed by his professor title, or Charles by those who are close to him.
* Comicbook/{{Magneto}} is often referred to as Erik, although usually only by Xavier, Mystique, and Beast.
* Comicbook/{{Mystique}} is frequently called Raven by Charles and Hank. But in ''Film/XMenTheLastStand'', a captive Mystique takes extreme umbrage at being referred to by her "slave name" of Raven, at least by humans. This apparently glaring contradiction can perhaps be explained by the probable sense of betrayal and/or abandonment Raven/Mystique feels toward Charles and Hank after the events of ''Film/XMenFirstClass''; note that Magneto, her newest and longest enduring confidant (at least until ''Film/XMenTheLastStand'') exclusively calls her "Mystique".
* 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 Comicbook/{{Beast|Marvel Comics}} 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.
* Comicbook/{{Storm|MarvelComics}} is the lone aversion. She's almost always called by her codename 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.

* Bobby has no codename in the first movie, introduces himself to Wolverine as Comicbook/{{Iceman|MarvelComics}} 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.
* Comicbook/{{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, Negasonic Teenage Warhead.
* The name Comicbook/{{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/WarrenWorthingtonIII's codename Angel is never used in ''Film/XMenTheLastStand'', but then inverted in ''Apocalypse'', being referred to only as "Angel."

** Comicbook/{{Sabretooth}} is only called "Victor" throughout ''Film/XMenOriginsWolverine''.

** 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.

** [[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.").
** Inverted by Comicbook/{{Psylocke}}, who is only called by her codename.

** Laura is never actually called Comicbook/{{X 23}} in the film, and even Pierce calls her Laura. For one thing, because of AdaptationDistillation she's no longer ''the'' X-23, but just one of a series of mutants created under the X-23 project (as a MythologyGag, she's X-23-23). The only time we see X-23 used is when Logan is skimming through the Transigen documents Gabriela stole, and it appears on the kids' medical files.

** In fact there's an ''inversion'' for many of the characters. With the exception of Peter, the various members of Comicbook/XForce are ''only'' ever referred by their codenames (Comicbook/{{Domino|MarvelComics}}, ComicBook/{{Shatterstar}}, Bedlam, Vanisher, and Zeitgeist), while Comicbook/{{Cable}} is never called Nathan Summers.

* Comicbook/{{Storm}} is the lone aversion. She's almost always called by her codename 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.

* Bobby has no codename in the first movie, introduces himself to Wolverine as Comicbook/{{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.

* Comicbook/{{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.

** 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.

* The code name Comicbook/ProfessorX is only used twice in both ''Film/XMenFirstClass'' and the first ''[[Film/XMen1 X-Men]]'', and Xavier brushes it off. He's more commonly addressed by his professor title, or Charles by those who are close to him.

* Comicbook/{{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.

* Comicbook/{{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]].
