History OnlyKnownByTheirNickname / AnimeAndManga

* C.C. (pronounced "C-Two") in ''Anime/CodeGeass'' 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.

* 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".

** In Japanese, [[TheHero Son Goku]] is often referred to by his family name "Son," or sometimes "Son-[[JapaneseHonorifics kun]]" by Bulma, instead of his given name. However, in western translations and dubs, he's generally only called "Goku."

** In Japanese, [[TheHero Son Goku]] is often referred to by his family name "Son," or sometimes "Son-[[{{Honorifics}} kun]]" by Bulma, instead of his given name. However, in western translations and dubs, he's generally only called "Goku."

** Toshinori "All Might" Yagi is only ever regularly referred to by his real name by Gran Torino.

* ''LightNovel/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.

* V. T. from ''Anime/CowboyBebop'' 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.

* ''LightNovel/ACertainMagicalIndex'':

* ''Anime/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.

* 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.
* Kyon and his sister in ''LightNovel/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".

* Katarina from ''LightNovel/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).

* The title character of ''LightNovel/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.

* D of ''LightNovel/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.

** Played straight with "Fuuki Iinchou", who is only referred to as her title, literally meaning "Discipline Committee Chairperson", or Yoshiko's EmbarrassingNickname for her: "[[GagBoobs Boob]] President".

* Takeshi Goda in ''Manga/{{Doraemon}}'' is commonly known as Gian. Some of the characters such as Shizuka and Gian's mother still call him Takeshi.

* The villain in ''Manga/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.

* ''LightNovel/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.

* 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 [[KillEmAll what Kafuka is likely to ultimately do to her classmates]].

** 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. He also fights in martial arts tournaments under the alter ego Jackie Chun. As with Piccolo and Kami, we never do learn his birth name.

** 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".

** 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 by "Nyamo".

** In Japanese, Goku is often referred to as "Son" or sometime "Son-[[{{Honorifics}} Kun]]" by Buluma instead of his full name of "Son Goku" which doubles for the name for his family name which goes by "Son Family". However with western translations and dubs just "Goku" is used to refer to TheHero.
*** Actually, when you think about it, Goku is his Earth nickname, while his birth name is "Kakarot" ([[PunnyName Carrot]]); so Vegeta, Nappa, Raditz and Broly are the only ones who referring to Goku correctly.
** Piccolo/Kami are in a similar situation to Goku; but, unlike him, they don't even know their birth name, and were once one being who called to Earth before spiting [[LiteralSplitPersonality into two beings]]: one good, called Kami (God); the other bad, named Piccolo (flute). When they fused back together, Piccolo whose in control of the body says he's just the "Nameless Namekian" despite Goku trying to cal him "Kamiccolo".
** Muten Rōshi/Master Roshi is usually referred as "Tutle Hermit" or sometimes "Master" by Goku and Krillin, and there also his alter ego Jackie Chun. Ditto for Roshi's [[TheRival rival]] Master Shen; he goes by "Crane Hermit" or "Master Crane", and only Roshi calls him by his real name.
** Androids 17 & 18, who were originally normal human teenagers named Lapis & Lazuli before being captured and turned into machines by Dr. Gero, are nonetheless only ever referred to in-universe by their robotic names, 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 wasn't until WordOfGod established it that they even had real names to begin with.

* ''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.

* C.C. (pronounced "C-Two") in ''Anime/CodeGeass'' 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.

* 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]]).

* Kyon and his sister in ''LightNovel/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".

* ''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.

*** Actually, when you think about it, Goku is his Earth nickname, while his birth name is "Kakarot" ([[PunnyName Carrot]]); so Vegeta, Nappa, Raddiz and Broly are the only ones who referring to Goku correctly.

** 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.

** 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.

** Only a few characters call Shark from ''Anime/YuGiOhZEXAL'' by his name Ryoga Kamishiro.

* 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 Sanae is only ever called "Georgie".
