->'''[[GameShowHost Skipper]]:''' When did Barbie first get a belly button?\\
'''[[TheDitz Teresa]]:''' What's a belly button?
-->--''WebAnimation/BarbieLifeInTheDreamhouse'', "Let's Make a Doll"[[note]]By the way, Creator/{{Mattel}} didn't start making Franchise/{{Barbie}} dolls with belly buttons until 1999.[[/note]]

It's a fact of life--no matter how placental a mammal is, clones don't have belly buttons. It's a common plot device used to distinguish those inferior, artificially created creatures from natural, unique human beings. Makes those knowledgeable of human physiology wonder just how these people developed, not having ever been attached to placentas before.

Natural clones such as identical twins don't count. They get to keep their navels.

[[JustifiedTrope Justified]] if the process for creating the beings ''somehow'' has nothing to do with fetal development, or if the species isn't even placental in the first place. It is common in magical constructs such as homunculi too, and of artificial beings in general.

See Also BarbieDollAnatomy where other attributes are missing.

[[AC:Anime & Manga]]
* {{Youkai}} in ''Manga/TokimekiMononokeJogakkou'' lack bellybuttons, so [[StrangerInAStrangeSchool Arare]] has to keep hers hidden to avoid being found out as a human.
* An early chapter of ''Manga/DoctorSlump'' has RobotGirl Arale worried because she lacks a navel and her classmates find that weird, so she wants one. Except her creator [[DirtyOldMan Senbei]] thinks she wants something a bit lower, which he's never seen because of Japanese censorship. HilarityEnsues.
* The main character in ''Manga/DokonjoGaeru'' is a frog, and they naturally don't have bellybuttons. This was pointed out a few times, and is even part of the lyrics in one of the ending songs.

[[AC:Comic Books]]
* ComicBook/{{Superboy}} never cared for this until a crossover with ComicBook/{{Icon}}, when he saw Rocket's navel and noticed he didn't have one.

* Rocky from ''Film/TheRockyHorrorPictureShow'' has no navel.
* The absence of a navel is pointed out when one of the creatures from ''Film/TheBrood'' is examined.


* In the Literature/DoctorWhoNewAdventures, Time Lords are constructed by machines and so lack navels. The Doctor is an exception.
** In the Literature/EighthDoctorAdventures book ''[[Recap/EighthDoctorAdventuresTheBlueAngel The Blue Angel]]'', an AmbiguouslyHuman AlternateUniverse version of the Doctor doesn't have one.
* Dejah Thoris from ''Literature/JohnCarterOfMars'', being Martian, an egg-laying species, has no bellybutton.
* In ''[[Literature/DreamPark The Barsoom Project]]'', Martin Qaterliaraq is an Inuit shaman character in the Fimbulwinter Game. His lack of a navel is an early indication that his character was crafted from molded lava by the Raven, not born.
* Though not a clone, and though the story isn't science fiction, the character Pilate Dead (the sister of the second Macon Dead) from Toni Morrison's ''Literature/SongOfSolomon'' is said to be born without a belly button (her umbilical cord shriveled up and fell off, leaving smooth, hairless, scarless skin).
* Magnus Bane from ''Literature/TheMortalInstruments'', being a warlock (half human[=/=]half demon), he has no bellybutton.
* In the ''Literature/{{Nightside}}'' books, Lilith is navel-less when she arrives, probably because she's an EldritchAbomination who made the body for convenience's sake.

* The in-vitroes from ''Series/SpaceAboveAndBeyond'' lacked standard belly-buttons. Instead, they had nipple-like bumps on the back of their necks from there the artificial placentas attached to them in the womb-tanks.
* On ''Series/MorkAndMindy'' after M&M got married and had sex for the first time, Mork proved he had laid an egg by showing his navel - since he's an Orkan he doesn't have one from the natural gestation process. [[RetCon Other than all the times he'd shown his belly before that episode and we'd seen it.]]
* In ''Series/TheBrittasEmpire'', Gordon doesn't have a belly button after some plastic surgery following his return from the dead (ItMakesSenseInContext, sorta)
* Luke Smith from ''Series/TheSarahJaneAdventures'' also lacks a navel, due to being created by the Bane.
* A rather bizarre and FridgeLogic-filled example: in ''{{Sorry}}'''s ItsAWonderfulPlot episode, Timothy loses his belly button because "he was never born".
* The ''Series/{{Charmed}}'' episode "Size Matters" has a demonic construct who demonstrates to Paige that he's not like ordinary people by showing her that he lacks a belly button.
* On the show ''Series/KyleXY'', the fact that he has no belly button was what alerted the people who found him that he was not quite normal.
* [[SelfDemonstratingArticle Clone]] from the Creator/{{BBC}}3 series [[ShapedLikeItself Clone]], has this. Or doesn't have this. YOU KNOW.

* In ''VideoGame/ChronoTrigger'', at one point of the game your party is captured. Your team may, at one point, feign an illness of some kind to get out of their holding cell. [[BewitchedAmphibians Frog]] will pretend to have a hurting belly button. After the guard is fooled and taken care of, Frog will [[LampshadeHanging point out]] that amphibians (being hatched from eggs) [[TruthInTelevision don't have belly buttons]].

[[AC:Web Animation]]
* Strong Sad from ''WebAnimation/HomestarRunner'' has a belly button... ...but it was created by Strong Bad's power drill.

* In ''Webcomic/{{Unsounded}}'', [[SmallAnnoyingCreature Sette]] has no belly button in addition to her BarbieDollAnatomy, which WordOfGod says is her ''actual'' anatomy. This along with her having [[PettingZooPeople a long furry tail and abnormally sharp teeth]], not to mention a super sense of smell, all heavily imply that she's not totally human.
* ''Webcomic/TheOrderOfTheStick'': [[HornyDevils Sabine]], being a demon who was never "born" in the normal sense, doesn't have a belly-button ([[{{Humanshifting}} at least in her true succubus form]]).

[[AC:Western Animation]]
* An episode of ''WesternAnimation/TheSimpsons'' involves Homer's life being invaded by an army of clones of himself. The clones, predictably enough, lack belly buttons.
* An episode of ''WesternAnimation/AmericanDad'' involves Steve and Snot cloning their high school's most popular girls so they can go with their clones to the prom. Stan only realizes that the girls are clones when he tells one of them to get a belly button ring and she responds that she doesn't have a belly button.
* WesternAnimation/ThePowerpuffGirls were designed without belly buttons, seeing as how they were scientifically created as opposed to being born naturally. This was subverted in the cover design of a CD of pop songs in which the girls, [[BareYourMidriff adorned in pop starlet's attire]], are drawn with belly buttons.
* One episode of ''WesternAnimation/VeggieTales'' featured [[MundaneMadeAwesome an entire song about Mr. Lunt's lack of a belly button]]. Khalil then explained ([[AWildRapperAppears in rap]]) that, as a gourd, his umbilical equivocal is on top of his head and that a prosthetic would be pointless.
* In ''WesternAnimation/StevenUniverse'', the Gems, being living rocks whose bodies are projections, lack navels. This can be seen in a few episodes with Garnet (Beach Party and Garnet's Universe) or anytime Lapis Lazuli shows up. [[HalfHumanHybrid Steven]] has his [[HeartDrive gem]] ''in place'' of a navel.
** In a flashback, we see that one of the first things Amethyst did upon meeting Greg was pull up his shirt to look at his belly-button, suggesting some curiosity about the concept on their part.

[[AC:Real Life]]
* There is an old joke:
-->'''Q:''' If you go to Heaven and look for Adam and Eve, how will you know which two people are them?
-->'''A:''' They're the only two without belly buttons.
* Czech Model Karolina Kurkova (somewhat) famously [[http://news.bbc.co.uk/2/hi/7738144.stm has no navel]]. She's never disclosed exactly why, but her lack of a natural belly-button has given rise to accusations of over-airbrushing when she appears in photo spreads. Ironically, this has caused some photo editors to [[WeWillNotUsePhotoshopInTheFuture Photoshop]] one onto her photos, in order to avoid accusations of over photo-editing!
* Some laparoscopic surgical procedures use the belly button as a point of entry to keep any resulting scars from being conspicuous. Later overgrowth of skin as the entry-point heals may cause the patient's navel to shrink to almost nothing.
** Likewise, surgical repair of an umbilical hernia, or a rare congenital defect in which an infant's belly wall is incomplete at birth, may require the abdomen to be sutured shut, leaving a scar rather than a navel.
** Creator/AlfredHitchcock had no navel due to surgery.
* Depending on anatomical configuration, [[ConjoinedTwins parasitic twins]] may lack an independent umbilical cord during gestation, relying on their intact twin's bloodstream for survival.
