''[[http://www.fanfiction.net/s/2809863/1/Maternal_Instinct Maternal Instinct]]'' is the beginning of an entire universe of stories, and one of the most widely celebrated ''WesternAnimation/KimPossible'' fanfics out there. Written by [[http://www.fanfiction.net/~blackbird Blackbird]], writer of growing popularity among the ''WesternAnimation/KimPossible'' and ''WesternAnimation/TheBatman'' fandoms, who also borrows a few elements from popular writer [[http://www.fanfiction.net/u/941378/ NoDrogs]]. The stories are imaginative, the dialogue is always a treat to read, and the series is all around well-written and consistently entertaining.

The story begins, as many do, with one of Drakken's plans going awry. While trying to impregnate Kim Possible with a retrovirus fired from a special gun, he misses and hits Shego instead. This leads to Shego becoming pregnant, which turns her against her employer and causes her to seek out the "father:" Kim Possible.

Like many ComicBooks, the series features [[AlternateContinuity multiple continuities]]. There's a second branch of stories, called "Another Possibility", that follows right after a [[MultipleEndings different ending]] for the first story.

The series is also notable for its many, ''many'' [=OCs=], all of whom feel fully developed and fit right into the universe that the author has created. There are also more cameos that you can shake a stick at, which ventures into {{Crossover}} territory at times. The author has taken a break from the series at the moment, but it's far from over.

Now with a audio reading by [[https://www.youtube.com/watch?v=mkYYr1Akpk0&feature=youtu.be Martialartfruituser]]
!!This series of fanfics contains examples of:

* AbusiveParents: [[spoiler:Shego's parents weren't downright abusive, but certainly close minded and offering little to no comprehension.]]
* ActionGirl: The series is pretty much overloaded with them, to an even more ridiculous degree than the show.
* ActionMom: Kim. Shego too, but ''mainly'' Kim.
* ADayInTheLimelight: First there's ''"The Unknown Adventure of Ann Possible"'', where the title should tell you enough. After that, ''"Spotlight"'' is basically just a large collection of one-shots, each one focused on specific characters, so it's practically ''made'' of this trope.
* AIIsACrapshoot: Queen Bebe.
* AlphaBitch: ''"The Pathetic Tale of Bonnie Rockwaller"'' showcases what happens to this kind of character after high school. Asuka is this for Shin.
* AndThisIsFor:
** Kim starts using this trope against the Queen Bebe in their final battle.
** The lighthearted variant appears at the end of ''"Sidekick, No More,"'' in which Bonnie slaps Ron for leaving, then kisses him for coming back.
* BelligerentSexualTension: Between Catgirl and Will Du, if Stonehenge is to be believed anyway.
* BigDamnHeroes: All over the series.
* ButICantBePregnant
* ButtMonkey: Shin can sometimes feel like this.
--> '''Shin:''' "Why does my life always have to suck!?"
* BreakTheHaughty: What happens to Bonnie after high school. Her father got arrested for tax evasion, all her nice stuff got taken away, and she has to work at Smarty Mart just to stay in a crappy apartment. Fortunately, rather than laugh about it, Kim comes and rescues her.
* TheCameo: ''So'' many. Let's go down the list:
** Pretty much the entire cast of ''Series/{{Scrubs}}'', most famously Dr. Perry Cox.
** Sideburn and Prowl from ''{{Transformers}}''.
** [[WesternAnimation/TheVentureBrothers The Monarch]] was Drakken's cellmate, while Brock Samson gives Shin a ride to Wade's apartment.
** Creator/JeffDunham makes a televised appearance with Peanut.
** Earl and Randy from ''Series/MyNameIsEarl''.
** Shaun from ''Film/ShaunOfTheDead'' and Ash Williams from ''Franchise/EvilDead'' both work for Smarty Mart and like to eat lunch together.
** Bonnie has to stay late at work because [[Series/MarriedWithChildren Al Bundy]] was absent from the shoe department.
** Asuka Langley Soryuu from ''Anime/NeonGenesisEvangelion'' appears as Shin's high school rival, as does Asuka's guardian, Misato Katsuragi.
** Brian Fellows, a paranoid zookeeper from an SNL skit.
** The doctors from ''Series/NipTuck''.
** Felix introduces Ron to WebVideo/TheAngryVideoGameNerd while the latter is in the hospital.
* CantCatchUp: After her pregnancy, Shego is still struggling to get back in shape.
* CloningBlues: ''"Seeing Double"'' is built around this trope.
* {{Crossover}}: ''"The Unknown Adventure of Ann Possible"'' is this with ''Series/DoctorWho''.
* DeadpanSnarker: Shego, natch.
* DeathByChildbirth: Perhaps assisted by poison, but this happens to [[spoiler:Shego in ''"Another Possibility"''.]]
* DeliverUsFromEvil: Guess who?
* DeliveryGuy: [[spoiler:Ron and Dr. [=McCoy=] for Shego.]]
* DontTellMama: Shin's been there, [[CantGetAwayWithNuthin never succesfully]].
* {{Expy}}: The entire Justice Squad:
** White Knight is a pretty clear {{Superman}} ShoutOut, with a little bit of [[ComicBook/XMen Bishop]] thrown in.
** Spyder is modeled after {{Spiderman}}.
** Longbow has shades of ComicBook/{{Huntress}}.
** Catgirl is a playful allusion to ComicBook/{{Catwoman}}, right down to her secret identity: Felicia Kyle.
** Stonehenge is obviously based on [[ComicBook/FantasticFour The Thing]].
** Also, during ''"Sidekick, No More"'', Ron becomes one for [[GIJoe Snake Eyes]].
* GiveHerANormalLife: What Kim and Shego seem to want for Shin. [[spoiler:The daughter doesn't agree.]]
* GoodGirlsAvoidAbortion: Basically the first indication of Shego not being truly evil.
* HasTwoMommies: Like other writers, Blackbird borrowed [=NoDrogs=] plot about HomosexualReproduction, but with the twist of having Shego being the one who ends up pregnant with Kim's child.
* HumiliationConga: Not only did Bonnie lose everything after her father got busted for tax evasion, but most of her days at Smarty Mart tend to follow this pattern. The final nail in the coffin before she decides to turn to Kim for help is when her apartment caves in.
* InstantBirthJustAddWater: Perhaps justified [[spoiler:due to Shego having been infected with something to accelerate her delivery.]]
* LawOfInverseFertility: Shego was ''infertile.''
* LoadsAndLoadsOfCharacters: Between the author's veritable army of [=OCs=] and all the cameos he keeps bringing in, there's got to be at least two dozen recurring characters at this point, if not more.
* MamaDidntRaiseNoCriminal: Shego's mother feels this way.
* MostCommonSuperpower: Shin's friend Kieran is the most obvious case of this, though it applies to a large number of the female characters. For [[AuthorAppeal some reason]].
* NearVillainVictory: Queen Bebe comes closer to defeating Kim than perhaps any villain she's faced before.
* PregnantHostage: ''Twice.''
* PursuingParentalPerils: Not like Kim or Shego ever died, but Shin still tries to follow on their footsteps. Arguably, ItRunsInTheFamily. Played more straight with Alexandra, who - as fanarts of the character shows - takes upon her dead mother's suit in order to feel closer to the mother she never knew.
* RunningGag: Close to it, several characters tend to fall asleep together on a couch. The author himself said after the third time it happened, "I think the best thing to do about it at this point is to make it a bit of a running gag."
* [[SomeoneToRememberHimBy Someone To Remember Her By]]: To an extent, [[spoiler:Alexandra]] may be this for [[spoiler:Shego]] in ''"Another Possibility"''.
* TemptingFate: Bonnie remarks that the only thing that could get her to move out of her apartment would be if the floor caved in. Within a few scenes, that's exactly what happens.
* UnluckyChildhoodFriend: Ron. Unlike a lot of Kigo stories, he and Kim didn't break up on the best of terms. They remain friends, but it takes a long time before they can truly move past it. Kim falling for Shego doesn't help matters.
