* Italy's IdiotHair in ''AxisPowersHetalia'' is shown in the comic to be an "erogenous zone". It's unclear if the note was referring to his scalp reacting to the hair being pulled, or if he has actual feeling in the hair, but the fandom tends to run with the latter, and usually applies the same principle to the other curl-bearing nations. On a creepier note, at least one fic goes to the logical extreme of the hairs being sensitive and has one bleed when severed. Also, Norway's curl actually floats around, detached from his head.

* The UltimateMarvel version of [[FantasticFour Mr. Fantastic]]'s body is an infinitely extensible fluid-filled sack containing, in place of an alimentary canal and other organs, just a squishable bolus of microbes that perform all metabolic functions. Yes, we know; FailsBiologyForever. Chalk it up to RuleOfCool and leave it at that.
* PlasticMan is literally inorganic after his OriginStory; this actually makes him immune to [[{{Brainwashed}} Brainwashing]], since his brain itself is apparently plastic.

* About 1/400 people has their kidneys fused into a horseshoe-shape, which is mostly asymptomatic. {{Mel Gibson}} is one notable carrier.

* Human soldiers from ''[=~Old Man's War~=]'' have green photosyntesizing skin, cat eyes and nano-bots instead of blood.

* In the mystery story "The Image in the Mirror" by [=~Dorothy L. Sayers~=], a key plot point is that one of the characters has ''situs inversus''.

* The Sebeceans in ''Series/{{Farscape}}'' are [[spoiler: humans decended from SuperSoldiers who were genetically engineered by aliens long ago.]] They have improved physical strength and eyesight (humans are apparently practically blind by the standards of other races) but fewer redundant organs an an extreme ([[FateWorseThanDeath seriously]]) weakness to high temperatures.

Maybe the character was born a {{Mutant}}, or belong to a HumanSubspecies, or have gone far enough up the EvolutionaryLevels, or underwent ''extensive'' BioAugmentation of the essentially permanent kind... Or perhaps they were even created as an ArtificialHuman from the get-go. The bottom line is, this human character's biology, while not [[BizarreAlienBiology technically alien]], cannot be considered "normal human" by any stretch of the term, be it due to having extra organs (duplicate or not), wildly different biochemistry, abnormal nutritional requirements, or even possessing completely new cellular organelles.

* ''StarWars'': Humans, as well as all other living species in TheVerse, possess "midi-chlorians," mysterious organelles which have some intricate connection to {{the Force}}.

* Does [[http://en.wikipedia.org/wiki/Chimera_(genetics) chimerism]] count?

* While [[NeonGenesisEvangelion Rei Ayanami]] is {{canon}}ically known to be at least [[HalfHumanHybrid partially human]], the specifics aren't made clear. To compensate, {{Fanfic}}s tend to depict her with either this trope, BizarreAlienBiology, or ''both'', each in various ways. To list them all would be a herculean task, given the size of the fandom; one notably common issue, however, is whether or not she has an S
Engine/[[AlternateCharacterReading Organ]], and its exact role in her physiology.

* An... ''interesting'' and technically correct description of intercourse popped up in SomethingAwful (a middle-school teacher requested things to make her sex ed class memorable) that went something like "The man puts his [[GenderBender vagina-equivalent]] into the woman's [[NauseaFuel mucus (yes, as in snot)-lubricated orifice]] and [[OrificeInvasion shoots microscopic worms into her]] that will cause the growth of [[BodyHorror a watermelon-sized parasite]]".

Note that '''not all''' HumanSubspecies, {{Mutants}}, BioAugmentation, etc. lead to BizarreHumanBiology. They are only ''possible ways'' for attaining this trope.

* Souther ([[SpellMyNameWithAnS or however you want to Romanticize it]]) in ''FistOfTheNorthStar'' has ''silus invertus totalis'' - which means that Kenshiro's first attempt to defeat him fails utterly. You see, when the organs invert, so do the pressure points Hokuto Shinken relies on...

* [[http://en.wikipedia.org/wiki/HeLa HeLa]] is an immortal, single-celled organism with 82 chromosomes. It's also, arguably, Humanity's closest living relative.

* [[http://en.wikipedia.org/wiki/Situs_inversus Situs inversus]], especially the ''totalis'' version, is a congenital human condition where the internal organs are in reverse of where they normally are (heart on the right, liver on the left, etc.). Absent any actual congenital defects, such individuals can lead otherwise perfectly normal lives.

* In ''ParasiteEve'', the protagonist Aya possesses a more benign/passive form of the "evolved" strain of mitochondria serving as the franchise' BigBad, which are not only ''a self-aware HiveMind'' that can [[BodySnatcher hijack their "hosts"]] and act like TheVirus, they possess actual superpowers, which include [[PlayingWithFire spontaneous combustion]] and BodyHorror transformations!
