7	People who are OnlyKnownByTheirNickname in anime and manga.

9	----
10	* Since most of ''Literature/HalfPrince'' takes place in a game world a lot of the characters only know one another's screen names. This is most blatant with Prince, who goes well out of his way to keep anyone from learning he's really a female player, the student of his biggest fan, close friend of his kohai, and cousin of his first kiss.
11	* ''Literature/AccelWorld'' gives us Kuroyukihime ([[Literature/SnowWhite "Snow Black"]]), leader of Nega Nebulus and the main character's love interest. Even her digital ID, supposed to reveal a person's real information and is impossible to hack in-universe, displays her name as Kuroyukihime. One of her friends refers to her as Sa-chan, which is the closest hint it gives us to her real name.
12	* In ''Literature/AdachiAndShimamura'', after Shimamura moves up a year, she becomes acquainted with some of her new classmates. Since she doesn't recall their names and doesn't care about them enough to learn their names, she calls them "Pancho" "De Los" and "Sancho."
13	* ''Manga/AhAndMmAreAllSheSays'': Japanese publishers usually respect their authors' choice of {{Pen Name}}s, such that they seldom refer to authors in their real names. As a result, as of Chapter 22, Norush was only referred to under his real name Nogami Ryoushi ''twice'' -- once in the BossSubtitles when he is first introduced, and the second time, on the envelope in which the publisher sends him a complimentary copy of ''X+C'' his work is published in.
14	* ''Manga/AhoGirl'':
15	** Subverted with A-kun, since technically Oshieda-sensei refers to him by his proper first-name, "Akuru". Everybody else calls him "A-kun", which gets hilarious when the incredibly polite Sayaka adds an additional honorific and calls him "A-kun-san".
16	** Played straight with "Fuuki Iinchou", who is only referred to as her title, literally meaning "Discipline Committee Chairperson", or Yoshiko's EmbarrassingNickname for her: "Boob President".
17	* ''Anime/AkudamaDrive'': Each Akudama, along with the protagonist, is only known by a codename. This is also true with the Execution Division, being referred to only by their rank. Any other character who speaks just goes nameless.
18	* Tokidoki from ''Manga/{{Amatsuki}}'' is almost always known as Toki both inside and outside the story, mainly because his full name is described as "too weird". (It's Japanese for 'sometimes,' and while the Japanese do ''sometimes'' use words for names, just like any other language, that isn't one of them.)
19	* ''Manga/AssassinationClassroom'':
20	** Koro-sensei gets his nickname from his students, specifically from Kayano. [[spoiler:He doesn't have a real name, and he used to be called "Shinigami" when he was an assassin.]]
21	** After her classmates are tired of calling her "Jiritsu Shikou Kotei Houdai-san" all the time, they shortened her name to "Ritsu".
22	** Kimura's first name is not "Masayoshi", but "Justice". Since he's embarrassed by this name, he prefers the AlternateCharacterReading over his real name, but everyone calls him by his last name anyway. He does later embrace his real name, though.
23	** [[spoiler:Kayano's real name is "Akari Yukimura". It turns out that "Kaede Kayano" is actually the name of a one-shot character she once played and that she decided to use as an alias to infiltrate the class. Since she has come to like it, she wants everyone to keep calling her by her alias.]]
24	* ''Manga/AzumangaDaioh'':
25	** Ayumu "[[TheIdiotFromOsaka Osaka]]" Kasuga -- her teachers, friends, fans... she's the only person who uses her real name. On the class listings for the second year, she initially thinks she is not in Yukari's class, but then sees that her name is listed as "Osaka".
26	** To a lesser extent is Koyomi "Yomi" Mizuhara.
27	** Minamo "Nyamo" Kurosawa is a small example too. Early on in the series, everyone of the main cast switches from referring to her by her last name to referring to her as "Nyamo".
28	* The title character of ''Manga/{{Beelzebub}}'' is simply called Beel, or Baby Beel, by everyone. Justified, as his real name, [[OverlyLongName Kaiser de Emperana Beelzebub IV]] would be a mouthful... and Oga doesn't remember his full name anyway.
29	* Several members of ''Manga/BlackLagoon'''s cast are commonly referred to only by nicknames. The only one of the cast who has a name we actually know is real (and not just a nickname or an alias) is Rokuro Okajima, the main character, whom everyone just calls "Rock". Amongst other examples, "Revy" is a nickname (first name "Rebecca", nothing else known), "Dutch" is a nickname, "Balalaika" is a nickname, and "Hänsel and Gretel" are nicknames (but they have no real names anyway).
30	** Balalaika is later given a full name: Sofiya Irininskaya Pavlovena.
31	* ''Manga/BungoStrayDogs'' has Yumeno "Q" Kyuusaku (whose real name is never spoken aloud) and Oda "Odasaku" Sakunosuke. Also possibly the case with Mori, as Elise calls him Rintarou, which was the real name of the real-life Mori Ougai, which might imply that it's his real name as well.
32	* ''Literature/ACertainMagicalIndex'':
33	** Accelerator notes that he used to have a real name. A normal name. He even tells how many characters were in it (3?) but doesn't reveal what it was. He's only called Accelerator now.
34	** Index too. Presumably she wasn't named Index when she was born, but probably after she was forced to memorize an entire library of knowledge and had the rest of her memory wiped. Whatever the case, "Index Librorum Prohibitorum" is apparently her actual legal name now, as it appears on any form of ID she carries.
35	** Aogami Pierce[[note]]which literally means "the blue-haired guy with piercings"[[/note]] presumably has a real name as well. To us, though, he's just the blue-haired guy with piercings.
36	* ''Manga/CityHunter'': Umibozu's real name of Hayato Ijuin is only said once by Ryo and another by the daughter of his old commander, everyone else call him either Falcon (his codename as a mercenary) or Umibozu (a mocking nickname that Ryo gave him and stuck). Even Umibozu himself prefers being called with his nicknames.
37	* ''Manga/CodeBreaker'': The head of [[TerroristsWithoutACause Re:Code]] is only ever called "The One Being Sought", which is fine for [[TheOnlyOneAllowedToDefeatYou Ogami]] [[spoiler:who is also his [[CainAndAbel brother]]]], but sounds a bit odd coming from other members of Re:Code ("'The One Being Sought', what are our plans?").
38	* ''Anime/CodeGeass'':
39	** C.C. (pronounced "C-Two") is only known by these initials. The only time her real name was spoken out loud the viewer is only treated with the speaker's vague lip-movements. Supposedly, it had originally been planned that her true identity would have some relevance in the second season. But since ExecutiveMeddling significantly altered Season 2, that plan got dropped.
40	** V.V. ("V-Two") is in a similar situation. [[spoiler:Charles, his younger brother, would presumably remember what his real name was, but he doesn't reveal it, and only addresses V.V. as such. His true name is only revealed in databooks: "Victor zi Brittania".]]
41	* V. T. from the ''Anime/CowboyBebop'' episode "[[Recap/CowboyBebopSession7HeavyMetalQueen Heavy Metal Queen]]" runs a pool for people guessing her name. Her real name is Victoria Terpsichore. Vicious, the show's main antagonist, never reveals his true name either.
42	* The famed criminal Mister in ''Anime/CoyoteRagtimeShow'' is so called because he has as many aliases and false identities as there are stars in the sky and nobody knows what his real name actually is.
43	* The titular "beard gorilla" from ''Manga/DadTheBeardGorillaAndI'' is almost never called by his real name, Kouji. His niece gives him that nickname, and it just kind of sticks.
44	* ''Manga/DailyLivesOfHighSchoolBoys'':
45	** Sanada East's StudentCouncilPresident is only known as "Ringo-chan."
46	** The Literature Girl or "Yassan". Her real name was never released.
47	* The [[AntiHero hero]] of ''Anime/DarkerThanBlack'' is only known by his CodeName, Hei ("black" in Chinese) [[NamesToRunAwayFromReallyFast The Black Reaper]], BK-201 (his Messier number), and "Li Shengshun" (or some variation) as his NiceGuy civilian alias. Whatever his real name was we'll probably never know, as he gave it up a long time ago.
48	* ''Manga/DeathNote'':
49	** We never find out L's real name until the 13th, non-story book that explains everything in detail, which only came out well after the main story was over.
50	** Ditto for Matt, although both Mello's ([[spoiler:Mihael Kheel]]) and Near's ([[spoiler:Nate River]]) are revealed late in the story. In fact, many people go by nicknames in the series, since Kira knowing your real name is... problematic, to say the least. L even goes by multiple layers of nicknames.
51	* In ''Manga/DeliciousInDungeon'', [[spoiler: Izutsumi is known only as Asebi to Shuro's group. Team Touden finds out her real name later on.]]
52	* In ''Manga/TheDemonGirlNextDoor'', Yuko is given the title of "Shadow Mistress Yuko" when her demonic powers and features manifest, but that epithet quickly gets shortened to "Shamiko." It doesn't take long before literally everyone but Yuko's mother is calling her Shamiko, even her own ancestor Lilith. She gets so used to it that she even asks new acquaintances to ''not'' call her Yuko and use "Shamiko" instead, she signs her name as "Shadow Mistress Yuko," and her teachers and authority figures address her as "Miss Shadow Mistress." It's played with even on the other side of the FourthWall; the character bios on Volume 4 refers to her as "Shamiko (Yuko Yoshida)".
53	* Nearly everyone on the main cast of ''Manga/DenkiGaiNoHonyaSan'' is known only by their nickname, e.g. Fu Girl, Director, Sensei, Sommelier, and Kameko.
54	* The dub of ''Anime/DigimonAdventure'' does this to justify the [[DubNameChange changes in names]] despite not trying to hide that most of the characters normally live in Japan; the first episode introduces the main cast listing both their full names and the nicknames derived from them (to varying degrees of plausibility) which the characters are referred to thereafter. It becomes strange when their parents use these nicknames for them, especially "Izzy", which is a of shortening the character's ''last'' name, which is also their last name. The other series don't bother with such a thing.
55	* Senpai of ''Manga/DontToyWithMeMissNagatoro'' was going to give his name, but Nagatoro stopped him so she could keep calling him Senpai.
56	** In Chapter 74, his classmates call him "[[spoiler:Nao-kun]]" which is almost certainly a nickname for "[[spoiler:Naoto]]" in line with pre-serialization content.
57	* Takeshi Goda in ''Manga/{{Doraemon}}'' is commonly known as Gian. Only a handful of characters such as Shizuka and Gian's mother still call him Takeshi.
58	* ''Manga/DrStone'': "Suika". It isn't her real name, just a nickname referring to the mask she wears. Despite this, it's the only name she's known by, and she even refers to herself in the third person by that name.
59	* ''Franchise/DragonBall'':
60	** In Japanese, [[TheHero Son Goku]] is often referred to by his family name "Son," or sometimes "Son-[[UsefulNotes/JapaneseHonorifics kun]]" by Bulma, instead of his given name. However, in western translations and dubs, he's generally only called "Goku."
61	*** Actually, when you think about it, Goku is his Earth nickname, while his birth name is "Kakarot" (after [[EdibleThemeNaming carrots]]), so Vegeta, Nappa, Raditz and Broly are the only ones who refer to Goku correctly.
62	** Piccolo/Kami are in a similar situation to Goku; but, unlike him, they don't even know their birth name, and were once a single alien who came to Earth before splitting [[LiteralSplitPersonality into two beings]]: one good, assuming the role of Earth's Kami ("God") and thereafter known only by that title; the other evil, named Piccolo (after a small flute, as part of the musical ThemeNaming of him and his demon spawn). When they fuse back together, Piccolo, who is in control of the body, says he's just the "Nameless Namekian" despite Goku trying to call him "Kamiccolo".
63	** Muten Rōshi/Master Roshi/Kame Sen'nin. ''Muten Rōshi'' means "Martial Heaven OldMaster," so his dub name means "Master Old Master." He's more often called ''Kame Sen'nin'', meaning "Turtle Hermit," or sometimes just "Master" by Goku and Krillin. Even his driver's license calls him "Muten Rōshi," meaning we either never learn his real name at all, or [[HisNameReallyIsBarkeep he actually]] ''is'' [[MeaningfulName named]] "Martial Heaven Old Master." He also fights in martial arts tournaments under the alter ego Jackie Chun.
64	** Roshi's [[TheRival rival]] Master Shen goes by "Crane Hermit" or "Master Crane", and only Roshi calls him by his real name.
65	** Androids 17 and 18, who were originally normal human teenagers named Lapis and Lazuli before being captured and turned into machines by Dr. Gero, are nonetheless only ever referred to in-universe by their robotic designations, and they even seem to prefer it that way rather than returning to using their birth names. Even Krillin, who is Android 18's own ''husband'', only ever calls her "Android 18". This was a case so extreme that it took the WordOfGod to even give them real names at all.
66	** ''Anime/DragonBallSuper'': Even though Goku Black claims to be Son Goku, everyone else except his partner [[spoiler:Zamasu]] calls him "Goku Black" or just "Black" instead to differentiate him from the real Son Goku. Even after his true identity is revealed, he's still called "Black" for most of the time and is rarely called [[spoiler:"Zamasu", mostly to differentiate him from the other Zamasu]].
67	* Everyone (both in the show and in RealLife) calls the main erm... "heroine"... of ''Manga/ElfenLied'' "Lucy". The tail end of the manga [[spoiler:reveals her actual name is [[OnlyOneName Kaede]]]].
68	* In ''Manga/{{Erased}}'', the kids all call Jun Shiratori "Yuuki," meaning "courage," since he's always telling them to face their fears and speak their minds.
69	* ''Manga/Eyeshield21'':
70	** Shien Mushanokoji, the quarterback of the Seibu Wild Gunmen , is only called "The Kid" for several volumes before his name is revealed.
71	** Monta's real name is Raimon Taro, but due to a misunderstanding when he first introduced himself to Sena he's been called "Monta" by everyone but his mother ever since. Even his locker says "Monta" on it.
72	** Additionally, when Sena and Monta set out on the trail of the mysterious third founding Devil Bat, literally all they know about him is his nickname, Musashi, causing them to think he's JerkAss soccer player '''Mu'''ro '''Sa'''to'''shi'''. Musashi turns out to be a guy named Gen Takekura; the nickname is never directly explained, although "Takekura" and "Musashi" are two different ways to read the same kanji (武蔵).
73	** "Buffalo" Ujishima of the Seibu Wild Gunmen. Not that it can be helped, since his actual given name, "Baharou", is pronounced identically to "Buffalo" in Japanese.
74	** Patrick "Panther" Spencer is never called Patrick (or any permutation thereof) by anyone; his name is only mentioned as an answer to a [[FourthWallMailSlot "Devil Bat Spy"]] question.
75	* ''Manga/FairyTail'':
76	** The Oracion Seis all have codenames. Hoteye mentions that his real name is [[spoiler:Richard]], though. Cobra later tells Kinana that his name is [[spoiler:Erik]] but unlike Hoteye, he continues to use his codename afterward. [[spoiler:Eventually, they all choose to take up their old names again sans Brain with their HeelFaceTurn (again, sans Brain).]]
77	** The Black Dragon of the Apocalypse, Acnologia, is technically using another dragon's name as his own. His true [[spoiler:human]] name is never revealed, as even he himself admits [[TheDarkSideWillMakeYouForget he's forgotten it]], but he answers to the name "Acnologia" in order to never forget the dragon that [[FreudianExcuse destroyed his village, killed his loved ones, and betrayed his trust and friendship]], all of which started him down the path of becoming an OmnicidalManiac.
78	* ''Manga/FullmetalAlchemist'':
79	** Scar gets known as... well... "Scar" due the one he has on the face. He said he [[ThatManIsDead abandoned his name]], which is [[TheUnreveal never revealed]].
80	** The main antagonist is usually known as "Father" or "the Philosopher from the East", though his "true name" is [[HisNameReallyIsBarkeep Homunculus]]. More or less. His own 'father' calls him "Dwarf in the Flask".
81	* Nobody in ''Manga/GAGeijutsukaArtDesignClass'' calls Miyabi Oomichi "Miyabi". She's mainly referred by the main cast as "Professor," while Namiko calls her by the AlternateCharacterReading "Masa," and the FacelessMasses calls her "Oomichi-san".
82	* InUniverse in ''Anime/GaikingLegendOfDaikuMaryu''. After [[IdiotHero Daiya]] nicknamed the Crab Bunker "Kani Tank", it is only referred to as its real name during the most serious of moments... [[InsistentTerminology and by Puria all the time]].
83	* ''Manga/GhostHunt'':
84	** Kazuya Shibuya. If you have seen the show but can't recall who that is, it may be because everyone calls him "[[{{Narcissist}} Naru]]" for the entire show. [[spoiler:"Kazuya Shibuya" is not his real name either. It's Oliver Davies.]]
85	** There's also Takigawa, who everyone just calls "Bou-san." (Mr. Monk)
86	* Everybody in the Section 9 in ''Franchise/GhostInTheShell'' save for Chief Aramaki and Togusa, who has a family, only uses a code name or alias; in the ''[[Anime/GhostInTheShellStandAloneComplex Stand Alone Complex]]'' episode where their names are shown as suspects to an attempted armed coup their real names have been obscured or corrupted, showing only the familiar aliases.
87	* A lot of the recurring cast in ''Manga/GohanNoOtomo'' are given nicknames based on their TrademarkFavoriteFood, with their given name being unknown. The SalaryMan from Chapter 3 gets named Nametake, while the other regulars are called Scallop, Barley, and Marsh (short for [[SweetTooth marshmallow]]).
88	* From the ''Franchise/{{Gundam}}'' franchise, [[Anime/MobileSuitGundam Char]] [[Anime/MobileSuitGundamCharsCounterattack Aznable]] (at one time, [[Anime/MobileSuitZetaGundam Quattro Bajeena]]), [[Anime/MobileSuitGundamWing Zechs Marquise]], and even TheHero [[Anime/MobileSuitGundam00 Setsuna F. Seiei]]. (Real names: [[spoiler:Casval rem Deikun, Milliardo Peacecraft, Soran Ibrahim]])
89	** ''[[Anime/MobileFighterGGundam G Gundam]]'' has a twofer with "Touhou Fuhai" (Undefeated of the East), AKA Master Asia (which is arguably just a pragmatic short-hand for the former). Quite often, Domon will refer to him by both titles in quick succession ("Touhou Fuhai Master Asia!") The manga ''G Gundam: Fight 7th'' gives his original name as [[spoiler:Shuji Kurosu]].
90	* The villain in ''Anime/GunXSword'' is known only as the Claw, sometimes called "Comrade" by his allies. He rejected his real name long ago and it is never revealed.
91	** ''VideoGame/SuperRobotWarsK'' has confirmed The Claw Man's real name to be Koo Krying Kroo and he's William Woo's father.
92	* All the Zoanoids, some Zoalords, and even Lost Numbers are never given names in ''Manga/{{Guyver}}''. Some just have their model number type as a nickname. Some Zoalords seem to rename themselves after famous figures or fictional literary characters.
93	* Kyon and his sister in ''Literature/HaruhiSuzumiya'' -- their real names will likely never be revealed. "Kyon" is just an irritating nickname his aunt once gave him and that his sister spread, that ended up sticking despite all his efforts to discourage it. His sister doesn't even get ''that'' much; everyone just calls ''her'' "little sister".
94	** In "The Disappearence of Haruhi Suzumiya", an alternate dimension Haruhi asks Kyon for his name. After wondering whether to give his nickname (which this Haruhi wouldn't know) or his real name (which not even the Haruhi from his dimension would know), he ends up giving the obviously fake name this Haruhi might remember him by: [[MrSmith John Smith]]. She then goes on to call him John.
95	--->'''Kyon:''' When you say John, are you referring to me?\
96	'''Haruhi:''' Why go with Kyon when John's a much cooler name?
97	* Hajime's younger brother in ''Manga/ICantUnderstandWhatMyHusbandIsSaying'' is almost exclusively referred to by his pen name, [[MoustacheDePlume Mayotama]]. Only his mother calls him Youta.
98	* ''Literature/IHadThatSameDreamAgain'': When Nanoka finds a very sick black cat in the pouring rain, she dashes to the closest apartments and goes from door to door desperately knocking, hoping that someone will answer. The only person that answers their door is a 20-something woman with "Skank" scrawled on the nameplate over her door. Being way too young to know what that means, Nanoka just addresses her as Skank-san. The woman is very amused at this and just decides to run with it; as a result, her real name is never revealed.
99	* ''Manga/InoHeadGargoyle'': The "Little Grey Alien" never reveals her real name, though she does show Saejima [[BeautifulAllAlong her real face]].
100	* Gyro Zeppeli from ''Manga/JoJosBizarreAdventure Steel Ball Run''. His real name is [[spoiler: Julius Caesar]] Zeppeli.
101	* The members of the Tabletop Games club in ''Manga/KaguyaSamaLoveIsWar'' usually go by nicknames that can change as a result of penalty games. Of the three, Megako ([[PunnyName formerly Gigako, and before that Terako]]) never has her real name revealed [[spoiler:until she graduates]].
102	* The top eight members of Ragnarok in ''Manga/KenichiTheMightiestDisciple'' have codenames based in Myth/NorseMythology. Only three of them have their full names revealed during the story in which they appear. The three others who [[DefeatMeansFriendship join the Shinpaku Alliance]] don't have their names revealed for another hundred or so chapters.
103	* ''Manga/{{Kinnikuman}}'' has Curry Cook the Brutal Chojin. His backstory in Curry Cook: The Man of Holy Love and Fury reveals his real name in a conversation when he was a humble traveler. [[note]]It's Singh, by the way[[/note]].
104	* Mitsune "Kitsune" Konno from ''Manga/LoveHina''.
105	* [[EmpathicWeapon Devices]] in the ''Franchise/LyricalNanoha'' franchise are occasionally given Mascot Names by their users, nicknames that they're programmed to treat as if they were their real names. Terra Forming Unit IR-S07 from the ''[[Anime/MagicalGirlLyricalNanohaReflection Reflection]]''/''[[Anime/MagicalGirlLyricalNanohaDetonation Detonation]]'' duology is exclusively referred to by their Mascot Name "[[spoiler:Iris]]", since addressing someone that is [[AndroidsArePeopleToo essentially human by the series' standards]] by a serial number would be rather insulting.
106	* ''Anime/LucyMayOfTheSouthernRainbow'': The Australian Aboriginal man. His real name is unknown (due to the language barrier), so Lucy-May nicknames him "Hercules".
107	* ''Anime/{{Madlax}}'' is only known by her CodeName (which has its own sinister backstory), even to her liaisons, the closest thing she has to family. In fact, [[spoiler:she doesn't have any "real" name at all, since she isn't that real herself, in the first place.]]
108	* The Gaba Thieves in ''Manga/MagicalCircleGuruGuru'' make a deliberate point of only ever using nicknames to protect their identities. When Nike and Kukuri briefly join them, the leader Sly immediately gives them codenames. This is taken a step further with Sly himself, who [[EveryoneCallsHimBarkeep everyone calls "Ookashira"]], essentially meaning "Boss".
109	* ''Manga/MarchComesInLikeALion'':
110	** Hinata is primarily referred to by her shortened name, Hina or Hina-chan.
111	** "Smith" is revealed to be a nickname long after his introduction, when the manga unceremoniously reveals that his real name is Tatsuyuki Misumi.
112	* ''Anime/MazingerZ'':
113	** Boss from this series and the various spin-offs/sequels thereof (''Anime/GreatMazinger'', ''Anime/UFORoboGrendizer'', ''Anime/{{Mazinkaiser}}'', ''Anime/ShinMazinger'', ''Manga/ShinMazingerZero''...). He's claimed that even the author doesn't know his real name.
114	--->'''Boss''': Kabuto's close friend Boss. Even the author doesn't know my real name.
115	** During [[GrandFinale the final arc of the original manga]], Dr. Hell revealed that "Hell" was not his true name but a pseudonym... [[ObviouslyEvil that he nicknamed himself with]].
116	* Emperor Sōun from the [[ShoujoGenre shōjo]] manga ''Mikado no Shihō'' is only known as "Shiki" to almost everyone else except his mother.
117	* Quetzalcoatl from ''Manga/MissKobayashisDragonMaid'' is almost always referred to by the shortened name "Lucoa", probably because her full name would be quite a mouthful for a Japanese speaker. Likewise, Saikawa's older sister Nae is only ever called "Georgie" (the anime even implies that she's forgotten that Georgie isn't her real name).
118	* The entire cast of ''Manga/MolesterMan'', barring a few one-time characters. It's funny to see them calling each other "Molester Man" or "Miss Understanding" as if those were their real names, especially long after it's been established that he's ''not'' a molester.
119	* In ''Manga/{{Monster}}'', there is the mafia boss named The Baby. [[spoiler:His real name is given TheUnreveal treatment.]]
120	* The protagonist of ''Manga/MonsterMusume'' is rarely referred to by his real name, Kimihito Kurusu. The girls around him tend to use various nicknames for him, generally some variation of "Darling", "Master" or "Husband".
121	* ''Manga/MyHeroAcademia'' is about superheroes, so there are a fair number of both heroes and villains whose real names are either unknown or rarely used:
122	** Toshinori "All Might" Yagi is only ever regularly referred to by his real name by Gran Torino and Nana.
123	** Endeavor is always referred to by his hero name, Endeavor. There are absolutely no mentions of him as Enji Todoroki by any characters, not even his own family. Likewise, the civilian/papa side to him is barely there. Endeavor is practically his only identity, [[GloryHound which says a lot]]. The only person to call him otherwise is Gran Torino, as his senior (seniority privileges), but only by his surname of "Todoroki", as a warning not to engage Stain. Yet, quite some time later, Dabi would be the first to invoke his full name in the hope to get a rise out of him, finding commonalities between them both.
124	** Speaking of Gran Torino, he is an interesting example. The only person to ever call him by his real name, Sorahiko, was Nana Shimura, All Might's mentor and a close friend; everyone else calls him "Gran Torino". However, his full real name is Sorahiko Torino, so technically ''everyone'' is calling him by name without quite realizing it.
125	** Most of the Pro Heroes who work at UA High are examples (Recovery Girl, Snipe, Midnight, Present Mic, Power Loader, Lunch Rush, Ectoplasm, etc.). Present Mic's real name is given briefly during the flashback to how Shota "Eraser Head" Aizawa (who is ''not'' an example of this trope) got his hero name.
126	** Indeed, most Pro Heroes in general (Best Jeanist, Edgeshot, Gang Orca, Kamui Woods, Mt. Lady, etc.) haven't had their real names used in the narrative, and we only know their real names from supplemental databooks.
127	** Dabi of the League of Villains introduces himself by noting that's what he's going by at the moment, and refuses to give his real name when asked. [[spoiler:He later reveals himself as Shoto's older brother Toya.]]
128	** Almost no one calls the main villain, All For One, by his real name.
129	* Katarina from ''Literature/MyNextLifeAsAVillainessAllRoutesLeadToDoom'' never reveals what her name was prior to her reincarnation, and her past life is only ever referred to as "the monkey girl" (or "my friend" in Atsuko's side story).
130	* ''Manga/{{Naruto}}'':
131	** Yamato's real name is unknown and since his introduction he has just gone by the CodeName Tsunade gave him even after the mission he was given it for ended. Apparently he likes "Yamato" better than his real name, whatever it might be. Readers often confuse "Tenzo" to be his real name, but it's actually just the CodeName he used he worked with Kakashi. Given the more recently-revealed details of his background, it's entirely possible Yamato has no idea what his real name is and simply prefers to go by whatever his current code-name is for convenience's sake.
132	** We eventually find out [[spoiler:A and Killer Bee]] don't go by their real names, but rather nicknames that have been used by [[spoiler:the Raikage and his partner]] through their village's history.
133	* Nodame from ''Manga/NodameCantabile'' rarely gets called by her real name, Megumi Noda.
134	* The title character of ''Literature/NyarukoCrawlingWithLove'' introduces herself as [[Franchise/CthulhuMythos Nyarlahotep the Crawling Chaos]], adding "People call me Nyarko, but I have a real name". Later novels reveal that her true name is TheUnpronounceable, and even being able to comprehend it is quite a feat.
135	* ''Manga/OnePiece'':
136	** Franky's real name is Cutty Flam. "Franky" was a name given to him by Iceburg.
137	** Hachi is rarely ever called by his real name "Hatchan", since it sounds very cute.
138	** Edward Newgate and Marshall D. Teach are known almost exclusively as "Whitebeard" and "Blackbeard", respectively.
139	** Most people refer to the Admirals of the Marines by their color-coded alias, and rarely know or use their real names.
140	** During the Paramount War in Marineford, a flashback shows the Pirate King complaining to Whitebeard because everyone's started calling him "Gold Roger" when his real name is Gol D. Roger. By the present day hardly anyone refers to him using that name. The world knows him as the Pirate King Gold Roger.
141	** Many members of the Donquixote family are only known by their given codenames. The four family executives are codenamed for the four card suits; thus, Donquixote Rocinante is almost exclusively referred to as "Corazon", and we never learn Trebol's, Diamante's, or Pica's real names. Some of the underlings are the same way; we are explicitly told that "Buffalo" and "Baby 5" are codenames, but we never learn their real ones.
142	** Many notorious pirates are exclusively referred to by their nicknames by people who don't know them personally, see the many villains who only ever refer to Luffy as "Straw Hat".
143	** Charlotte "Big Mom" Linlin is usually only referred to by her epithet or simply "Mama" by her children ''and'' unrelated subordinates. Only those who knew Linlin in her younger days are on a FirstNameBasis with her.
144	* Kasanoda from ''Manga/OuranHighSchoolHostClub''. We're given his first name (which is Ritsu), but he's almost always referred to as Kasanoda or some [[AccidentalMisnaming mispronunciation]] of his name.
145	** Mori and Honey as well, except to [[FirstNameBasis each other]].
146	* In ''Manga/PandoraHearts'', legal contractors are often nicknamed after [[OurMonstersAreDifferent their Chain]], such as [[CreepyCrows Raven]], [[spoiler:who turns out to be [[FutureBadass Gilbert]] post-TimeSkip]], or [[MadHatter Hatter]], aka [[BunnyEarsLawyer Xerxes Break.]] [[spoiler:That name is also an alias: his birth name is [[IHatePastMe Kevin Regnard]].]] And then there is [[SilkHidingSteel Charlotte Baskerville]], whom everyone started calling "Lottie" after Jack came up with the nickname.
147	* We don't know the full names of the cast of ''Manga/PleaseTellMeGalkoChan''. The names used are merely based on their character archetypes: [[GyaruGirl Galko]], {{Otak\|u}}o, {{Ojou}}, and so on.
148	* Ash Ketchum in ''Anime/PokemonTheSeries'' is a downplayed example of this. Team Rocket always refer to him as "the Twerp". They almost never refer to him by his real name and you can probably count the number of times they've ever done so to his face on one hand.
149	* Due to a DubNameChange X and Y are this in translations of ''Manga/PokemonAdventures''. Their names are short for "Xavier" and "Yvonne", though in the original version their names are literally "X" and "Y".
150	* ''Anime/PuellaMagiMadokaMagica'': "Walpurgisnacht" is the moniker given by magical girls to [[TheDreaded one of the]] [[TheJuggernaut most powerful]] [[TheHeartless Witches]]. However, nobody knows what its true name is, not even [[ShrugOfGod official sources]] (instead referring to it as "[[MyNameIsQuestionMarks ?????]]").
151	* Kafuka Fura of ''Manga/SayonaraZetsubouSensei'' is using a false name derived from that of Franz Kafka. At one point there's a flashback to Nami's kindergarten class, and one of Nami's classmates, who looks like a younger Kafuka, is identified by the name An. It seems to be implied that Kafuka's real name is An Akagi, the Japanese title for ''Literature/AnneOfGreenGables'', in reference to Kafuka's [[ThePollyanna ultra-optimistic personality]]. The name/book title literally means "Red Anne", but is also a pun on "red end" in Engrish, and in both cases, refers to what Kafuka is likely to ultimately do to her classmates.
152	* ''Manga/SchoolLive'':
153	** SenseiChan Megumi Sakura is only ever referred to as "Megu-nee" by the characters, though she wishes they would refer to her as "Sakura-sensei".
154	** Yuuri is referred to as "Rii" more often than her full name.
155	** [[spoiler:Rii's sister]] is exclusively known as "Ruu".
156	* ''Manga/ShouwaGenrokuRakugoShinjuu'' has the protagonist Yotaro who doesn't even mention his own name, not even when first speaking to his rakugo idol Yakumo. Yotaro is a nickname given to him by Yakumo, and [[MeaningfulRename it means "fool" in rakugo slang]]. Less than halfway through the first episode of the anime, we get a guy from Yotaro's past and only then is this trope averted -- his real name is Kyoji.
157	* "Obi" from ''Manga/SnowWhiteWithTheRedHair'' goes by a number of nicknames and aliases depending on the situation and has been using Obi as if it were his name since starting to work for Zen. Zen did use what seemed like it was possibly Obi's real name when he gave him a nametag and the authority of working directly under the prince in an official position but Obi did not confirm the name.
158	* D of ''Literature/SoImASpiderSoWhat'' is one of the most powerful and feared gods in existence, but nobody knows her actual name. She suggested Sariel call her D in the distant past and has been using that in place of a name since.
159	* All three main characters in ''Manga/TheSpicyNinjaScrolls'' consistently go by the names given to them by their master Gouki, a deliberate decision so as to better signify how a ninja leaves their old life behind when they become one. Shichimi's real name, Rekka, is only ever used by his family when he visits them, while Oroshi's real name [[spoiler:Siknu]] was only ever used [[spoiler:when his father Akuro was still alive]], and neither he nor anyone else uses it by the present. Wasabi is actually a subversion, as it turns out [[spoiler:he didn't really have a name to begin with [[TomatoInTheMirror due to originally being part of the Kukunochi]] -- the name "Wasabi" originally belonged to a boy whose life he wished to have, causing him to adopt it as his own nickname and later Gouki to also call him by it.]] The closest thing Wasabi has to a real "name" is [[spoiler:"Scion of the Kukunochi"]].
160	* The ''Manga/{{Splatoon}}'' manga has all its original characters be known only by a defining piece of clothing, with all their clothing being based on actual gear from the games. Blue Team, in particular, is all named after their headgear: Goggles wears the Pilot Goggles, Headphones wears the Studio Headphones, Specs wears the Retro Specs, and Bobble Hat wears... well, the Bobble Hat.
161	* ''Manga/SpyXFamily'': Agent Twilight's real name is never revealed in the manga. "Loid Forger" is just the latest of a long line of assumed identities, and everyone who knew his birth name died in the last war between Ostania and Westalis. Even in flashbacks to his childhood, his name is blanked out like a censored document.
162	* Prince Marse in ''Manga/TalesOfWeddingRings''. His given name is Marmarugias, but nobody calls him that.
163	* Oshizu in ''Manga/ToLoveRu''. Her real name is Shizu Murasame, but she likes to be called Oshizu better.
164	* In ''Anime/YokaiWatch'' we have Barnaby "Bear" Bernstein (Gorouta "Kuma" Kumashina in Japan) who is never referred to by his proper name. To a lesser extent other characters often have shortened versions of their names, like "Eddie" and "Katie". Even Nathan's parents only call him "Nate".
165	* ''Franchise/YuGiOh'':
166	** The Pharaoh in the English dub of ''Anime/YuGiOh''. His real name is unknown and is a plot point in the last season, so the only thing his friends can call him is by his title, which they use in lieu of a name, rather than as a respectful gesture or as a title as Ishizu and Shadi would use it. In the Japanese version, he's called "Yugi" until his true name is revealed. He's also often been called "Yami", a prefix that also extends to Thief King Bakura (whose signature Millennium Item went to ''Ryo'' Bakura) and Marik.
167	** Ryo Marufuji, the Kaiser, of ''Anime/YuGiOhGX''. There is a time when people call him Hell Kaiser until they call him only Kaiser again.
168	** Only a few characters call Shark from ''Anime/YuGiOhZEXAL'' by his name Ryoga Kamishiro (Reginald Kastle in the English dub). One of those is his twin sister Rio.
169	* ''Manga/YuuutsuKunToSuccubusSan'': The succubus main character's name, Sakuma, is an alias. According to her, succubi keep their real names close to the chest, even among relatives. The way she explains it ''sounds'' like [[IKnowYourTrueName knowing a succubus's true name is a big deal]], but the intense blush she gets just from Yuu calling her "Sakuma-san" implies it's more the intimacy behind being on a FirstNameBasis.
