Laconic: Bizarre Alien Biology for humans. (A/N: Gah, need a better laconic definition. Any suggestions?)

Maybe the character was born a Mutant, or belong to a Human Subspecies, or have gone far enough up the Evolutionary Levels, or underwent extensive Bio-Augmentation of the essentially permanent kind... Or perhaps they were even created as an Artificial Human from the get-go. The bottom line is, this human character's biology, while not 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.

The trope can come into two flavours:
  • Standard: These are fictitious in principle, and thus typically the domain of Speculative Fiction.
  • Truth in Television: some of the detailed aspects of our biology can be downright bizarre to us, even if they technically make sense. Additionally, there are real-life medical conditions that technically result in abnormalities to an otherwise healthy human biology (see Real Life section).

Note that not all Human Subspecies, Mutants, Bio-Augmentation, etc. lead to Bizarre Human Biology. They are only possible ways for attaining this trope.

Compare and contrast Bizarre Alien Biology, which may overlap with this trope in cases of Half Human Hybrids or Panspermia.

Examples (Standard flavor)

Comic Books
  • The Ultimate Marvel version of 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; Fails Biology Forever. Chalk it up to Rule of Cool and leave it at that.

Fan Work
  • While Rei Ayanami is canonically known to be at least partially human, the specifics aren't made clear. To compensate, Fanfics tend to depict her with either this trope, Bizarre Alien Biology, or both, each in various ways. To list them all would be a herculean task, given the size of the fandom; one notable aspect, however, is whether or not she has an S2 Engine/Organ, and its exact role in her physiology.

  • Star Wars: All living species in The Verse possess "midi-chlorians", mysterious organelles which have some intricate connection to the Force.


Live-action TV
  • The Sebeccans in Farscape are humans decended from Super Soldiers 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 (seriously) weakness to high temperatures.

Real Life
  • Situs inversus 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.
