History OnlyKnownByTheirNickname / WesternAnimation

* ''WesternAnimation/{{Castlevania}}'': Alucard introduces himself by his real name of Adrian Fahrenheit Țepeș, but nobody (not even his dad, mom or best friends) refers to him as Adrian once. Similarly Dracula is only known as Dracula rather than Vlad. Then there’s TheGhost the “Pirate of the Roads” whose real name fans will know is Grant Danasty.

** In the 2023 reboot, there's Zee, whose real name is Hezekias, and Scary Girl, whose real name is Lauren. They are both only referred to by said real names during their introductions.

* On ''WesternAnimation/{{Daria}}'' practically everyone calls Michael Jackson Mackenzie "[[SatelliteCharacter Mack]]" or ([[EmbarrassingNickname to his annoyance]]) "Mack-Daddy;" the one exception is his girlfriend, [[ExtracurricularEnthusiast Jodie]]. Likewise, Charles Ruttheimer III is "Chuck" to himself and his cousins but "[[ExtravertedNerd Upchuck]]" to everyone else.

** Pinkamena Diane Pie, better known to everyone as [[{{Cloudcuckoolander}} Pinkie]] [[GenkiGirl Pie.]] She's the OddNameOut when it comes to the main characters because "Pinkie" is a nickname, in addition to her having a middle name. This may also extend to the rest of her family, as one of her older sisters is named Maudalina "Maud" Daisy Pie.
** Mi Amore Cadenza is always called "Cadance". This led to Twilight briefly being enraged about her brother marrying her, since she didn't recognize the name on the wedding invitation until he reminded her.

** Spinelli is known by her last name, with her first name being Ashley. The reason she kept it a secret isn't because she hates her name, but rather because all the other Ashleys at the school are a group of shallow {{Valley Girl}}s, while Spinelli is a tomboy who hates girly things, so she'd rather avoid that affiliation. When it does become known, the other Ashleys force her into servitude until T.J. is able to figure out a plan to free her.
** In addition to the above, "Mikey" is short for Michael, "Vince" is short for Vincent, and "Gus" is short for Gustav. Of the main six, only Gretchen presumably goes by her full name, and even the name "Gretchen" originated in RealLife as a German nickname for "Margarethe".

** Norville "Shaggy" Rogers, in most incarnations, mostly goes by his nickname. He's never referred to by his real name in the original series, and it rarely pops up in most other media. The only exception is in ''WesternAnimation/{{Velma}}'', in which he solely goes by his real name and never goes by Shaggy.

* ''WesternAnimation/CaptainPlanetAndThePlaneteers'': Wheeler of the Planeteers. It's pretty obviously a nickname, but we never do learn what his name is in the show.

** Shego is the only major villain not to have her real name ever mentioned. She's the second most common villain alongside Drakken (who is referred to several times by his name Drww Lipsky), but the closest we get is heavy implications that her surname is "Go" in "Stop Team Go". Her brothers -- Hego, Mego, and the Wego twins -- also are only referred to as such.

** In ''Revenge of the Island'', there are two: [[OneLetterName B]], whose real name is Beverly, and Lightning, whose real name is Rudolph. Both are embarrassed by said real names.

** In the 2023 reboot, there's Zee, whose real name is Hezekias, and Scary Girl, which is a nickname the other contestants give her due to her... [[NightmareFetishist antics]]. Her real name is Lauren, but much like Zee, she's only ever called by it during her introduction, with everyone referring to her as "Scary Girl" afterwards.

** In the 2023 reboot, there's Scary Girl, which is a nickname the other contestants give her due to her... [[NightmareFetishist antics]]. Her real name is Lauren, but she's only ever called by it during her introduction, with everyone referring to her as "Scary Girl" afterwards.

* ''WesternAnimation/SpongeBobSquarePants'': The old lady's rather shriveled mother is unnamed, only being given the nickname "Baby Prunes" by [=SpongeBob=] in "Biddy Sitting".

** Shaggy's name is "Norville Rogers", but you could easily watch a hundred episodes without actually hearing him called that.

* ''WesternAnimation/ThePowerpuffGirls'': The leech man in "The Headsucker's Moxy" is called "the Robbing Leech" by the girls, with no knowing of whatever his true name is.

* ''WesternAnimation/TeenTitans'': Unlike on ''WesternAnimation/JusticeLeague'' or the [[ComicBook/TeenTitans source comics]], the heroes never call each other by their civilian names as seen in the comics. In fact, the only characters who are explicitly referred to with their real names at any point are Beast Boy ([[EmbarrassingFirstName Garfield]]) and Starfire (Koriand'r, with Starfire [[ThisIsMyNameOnForeign the English translation of said name]]), with family both addressing them as such. Outside of that, Cyborg uses his last name of "Stone" for an undercover mission, and while this Robin was originally [[LegacyCharacter meant to be ambiguous]], it is heavily implied throughout the show's run to be Dick Grayson. Finally, Raven is actually a complete aversion, as Raven ''is'' her birth name; the "Rachel Roth" that some fans of the show throw around is the alias she uses for civilian outings.

* Robin and ComicBook/{{Superboy}} in ''WesternAnimation/YoungJustice'', unlike the rest of the team. Robin because Batman insists that his identity is kept secret, and Superboy because he doesn't have any other name. Artemis is a special case where her real name is Artemis, but the others (except possibly Robin, who goes to her school) don't know that. Rob's actually a double example: except for Wally, the team only knows him as "Robin", and his civilian friends and family only call him "Dick". When Superboy starts school, he takes the name "Conner Kent".

* ''WesternAnimation/TheSimpsons'':
** Krusty, Sideshow Mel and Sideshow Bob might be borderline examples of this; while they do have full names (Krusty's is Herschel Shmoikel Pinchas Yerucham Krustofski, Mel's is Melvin Van Horne and Bob's is Robert Underdunk Terwilliger), they're rarely used on the show (Krusty's ''full'' name is never used; the most we hear is Herschel Krustofski).
** As for the Simpsons themselves, there are Bartholomew "Bart" Simpson, Margaret "Maggie" Simpson and Marjorie "Marge" Simpson. Whenever someone actually uses Maggie's full name, Homer has no idea who they're talking about.
** Comic Book Guy was given the canon name Jeff Albertson in "Homer and Ned's Hail Mary Pass", but you'd be forgiven for not knowing it. The subtitles for the 20th season [=DVD=] box set label him simply "Jeff". Interestingly, voice actor Hank Azaria has stated that the person upon whom he based Comic Book Guy's voice was a college dorm mate that everyone knew as "F".
