[[http://www.fanfiction.net/s/2796006/1/Disappearing_Doctor Disappearing Doctor]] is part of a series of ''KimPossible'' fanfics written by Adam Leigh, who goes by [=TempestDash=] on FanfictionDotNet. It lies in the middle of two other stories, [[http://www.fanfiction.net/s/2813388/1/The_Family_Value The Family Value]] and [[http://www.fanfiction.net/s/3420996/1/Apocolocyntosis Apocolocyntosis]]. The series is a very subtle {{Crossover}} between KP and ''BubblegumCrisis'', though the former is emphasized more.

''The Family Value'' is told in the form of Shego's diary as she discovers the truth about Team Go and the mysterious [=VersaGene=] corporation that has been their benefactor ever since the incident that created them. What she learns puts that incident, as well as how she sees the world, in a whole new light, and starts her down the road to villainy.

''Disappearing Doctor'' begins with Drakken being kidnapped by a mysterious figure. His mother goes looking for him, posting a hit on Kim's website in addition to coercing Shego into helping. This forces Kim and Shego into an uneasy partnership, and things only get stranger as they work with Global Justice to uncover a conspiracy that goes back forty years. The story ends on something of a dark note, but leaves plenty of room open for a sequel.

''Apocolocyntosis'' dispenses with any pretense of subtlety and dives full-bore into the mythology of the series, introducing a web of connections that is convoluted enough to be confusing but still easy enough to keep track of if you pay attention. The story is told in episodic format, with each chapter being somewhat self-contained. After an almost four year hiatus, the story has finally been updated.

The series is notable for introducing serious elements to the KP universe while still preserving its trademark cartoon wit. The characters are well-written and the prose is enticingly poetic while still retaining an epic feel. The plot is amazingly layered and complex while still being smooth and flowing, and the whole thing feels like a grand adventure.

!!''The Family Value'' provides examples of:

* CassandraTruth: When Shego goes to Hego with [[spoiler: the revelation that their whole lives are one big genetic experiment,]] he doesn't believe her.
* CorruptCorporateExecutive: Quincy Masada, AKA The Architect.
* StartOfDarkness: This details Shego's.

!!''Disappearing Doctor'' provides examples of:

* ActionGirl: Kim, of course.
* AncientArtifact: The Mantle of Tenoch.
* BigBad: Gemini, for most of the story.
* BiggerBad: [[spoiler: Angela Lipsky, aka Atomic Andy.]]
* BadassBookworm: Agent Vicki Grimes, who was at one point a GJ field agent and one of the leading researchers on The Ron Factor. She's the one who cracks the mystery surrounding the break-in.
* BadassTeacher: Dr. Richard Vedas, who is [[spoiler: a former GJ agent]] and, in his own words, "actually rather good at fighting."
* BadGuyBar: Shego and Andy visit one in search of "The Survivor."
* TheChessmaster: [[spoiler: Angela Lipsky, AKA Atomic Andy.]] Though she prefers to think of it in terms of checkers, not chess.
* ColdOpen: Each chapter has a short scene before the title.
* DarkActionGirl: Shego.
* DeadpanSnarker: Shego, natch. Kim also gets a few lines like this.
* DownerEnding: Oh, boy. [[spoiler: Kim gets shot, Ron runs away to Yamanouchi to make himself more than just a burden, Shego has her soul ejected from her body and gets fifty years of her life stolen by Angela Lipsky, who also gets her powers in the deal and is now at large.]] And it started out so well, too.
* EnemyMine: Kim and Shego for pretty much the whole story.
* EvenEvilHasStandards: Shego discovers this about herself when witnessing the aftermath of [[spoiler: WWEE's assault on GJ.]]
* GilliganCut: Shego insists that she isn't going to let Kim sit on her lap a second time, only to loudly complain about finding themselves in that exact situation in the very next scene.
* ManBehindTheMan: [[spoiler: Or woman, in this case. Angela Lipsky orchestrated the entire affair, ordering Gemini to kidnap Drakken so that she could make a play for the Mantle of Tenoch. Gemini is not happy when he finds out he's been set up.]]
* NotSoDifferent: Shego points out that Kim and Drakken are very similar in that they're both obsessed with a completely ridiculous idea that has taken over their lives. The only difference is that one wants to save the world while the other desires to conquer it.
* ObfuscatingStupidity: Apparently, [[spoiler: Mrs. Lipsky regained her sense of self after the effects of the Kahn-Clasp Inhibitor wore off, but has been acting the part of a mother who knows nothing of her son's villainy in order to quietly manipulate things from behind the scenes.]]
* ReallySevenHundredYearsOld: [[spoiler: Dr. Rick.]]

!!''Apocolocyntosis'' provides examples of:

* AffablyEvil: Seņor Senior Senior. He offers to turn off his security system of deathtraps next time Kim visits as long as she calls ahead to make an appointment.
* AIIsACrapshoot: Black Shadow sees the world in very stark, black and white terms, designating anyone who breaks the law as evil and therefore deserving of death. This outlook was not helped by Wade's extremely sarcastic and misanthropic answers during his initial education.
* AndIMustScream: Black Shadow is actually [[spoiler: an elaborate network of nanobots that have taken over Wade's body, keeping his consciousness intact only so that Wade can help him grow, and granting him no control over the body. Wade eventually takes back control, very briefly, just long enough to tell everyone to run.]]
* AwesomeButImpractical: The initial version of [=DNAmy's=] de-aging drug gives Shego her youthful physique back, but also makes her extremely aggressive and focused only on the short term, leading her to engage in a series of street brawls rather than do anything useful. It also reverts after only a few hours.
* BigBad: There are multiple factions with sinister goals, but the one whose organization overlaps with all of them is [[spoiler: Angela Lipsky, aka Atomic Andy, the head of SCHEME.]]
* BecomingTheMask: [[spoiler: Will Du is given plastic surgery and assigned a new identity to go undercover in SCHEME and shut it down from the inside. His cover identity is blown almost immediately, so he makes up a new one on the spot: that he is a disgraced former GJ agent willing to go against GJ itself in order to serve true justice. After a while, this becomes his goal for real, and the final nail is driven into the coffin when he springs Dr. Drakken from a GJ prison.]]
* BroughtDownToNormal: Shego, after [[spoiler: having her powers stolen by Atomic Andy.]]
* ChekhovsGunman: Brick Flagg makes a cameo in the first episode in a dream sequence where his homework is attacking him (he thought he'd finally gotten out of school), then shows up later as [[spoiler: a member of Motor Ed's crew.]]
* DeathFakedForYou: GJ gave [[spoiler: Will Du]] a new identity in the wake of the bombing, in order to [[spoiler: send him to infiltrate SCHEME undercover.]]
* DontYouDarePityMe: Shego's reaction when Kim tries to help her.
* DreamLand: The Dreamtime Kingdom is an alternate dimension that exists within the Dreamtime, and is occupied by so many people that someone is always dreaming about it somewhere, which keeps the dream going.
* DreamWalker: Ron has been studying how to do this under Master Sensei, which allows him to keep tabs on his friends and investigate mysteries in the Dreamscape. There are others who can use this ability, such as Amanda Veers and [[spoiler: Monkey Fist.]]
* EmbarrassingFirstName: Dorothy, who was named after his mother. She was hardcore.
* EvenEvilHasStandards: Happens to Shego again when she realizes just how far [=DNAmy=] will go to get a test subject for the de-aging drug she commissioned.
* EvilRedhead: [[spoiler: Angela Lipsky, aka Atomic Andy.]]
* FaceHeelTurn: [[spoiler: Will Du. He's originally sent to infiltrate SCHEME undercover but thanks to Angela Lipsky's psychological manipulation and his own doubts about GJ he ends up BecomingTheMask.]]
* GeniusBruiser: Motor Ed. Axel also counts, as he apparently has a genius level IQ but no ambition beyond simple henchman.
* HiddenDepths: Motor Ed is a lot smarter and more insightful than his appearance and mannerisms would suggest, just like on the show.
* IChooseToStay: [[spoiler: Hog.]]
* ImmortalImmaturity: [[spoiler: Dr. Rick]] acts like a reasonably responsible adult, but Betty notes that he only seems to be interested in mortals when they have a certain mindset that they later grow out of, because he's still stuck in that mindset since he never has to get older and move past it.
* ImplacableMan: Black Shadow relentlessly pursues villains, and is able to take inhuman levels of punishment without even flinching. He can not only hold his own against six opponents, he is actually ''winning'' when [[spoiler: Wade briefly takes back control.]]
* InnocentInnuendo: Happens in episode three when [[spoiler: Malcolm is helping Kim with her Latin homework.]]
* InstantExpert: Averted. Even after six months of training, Ron is still only marginally better than he was before leaving for Yamanouchi.
* LightningBruiser: Black Shadow.
* MakeUpOrBreakUp: Kim and Ron have to decide this after realizing that they will never agree on whether Ron was right to leave for Yamanouchi. Kim feels like he abandoned her, while Ron insists that he failed to protect her and wants to get better at it. She counters by saying that she doesn't need protecting, and if anyone does need to be protected, it's him. [[spoiler: They break up, but remain friends and partners.]]
* {{Metaphorgotten}}: Brick tries unsuccessfully to build a metaphor around the dead horse scene from ''Film/TheGodfather''.
* {{Nanomachines}}: The technology behind [[spoiler: Black Shadow.]]
* NebulousEvilOrganization: SCHEME.
* NothingUpMySleeve: Shego has a pistol up hers, which is very effective against Kim considering her new gun phobia.
* OppositeSexClone: [[spoiler: Ken Possible, though technically he's just Kim from another dimension where a virus caused over 90 percent of the population to swap sexes overnight.]]
* PrecisionFStrike: There isn't a whole lot of foul language in the story, which makes this line from Shego all the more effective.
-->'''Shego''': You come in here with that ''fucking'' face of yours all full of pity and sadness for me because, oh BOO-HOO, I got screwed by my own damn greed. [[DontYouDarePityMe I don't want that from anyone]], least of all ''YOU''!
* SilentBob: Axel. He can talk, but chooses not to mostly because he has a habit of pointing out uncomfortable truths so often that his employers end up telling him to shut it.
* SophisticatedAsHell: Most of Motor Ed's lines, but especially this one:
-->'''Motor Ed''': Nah babe, listen. If you focus the fold at the right distance from the car, it'll generate a field that will significantly reduce the real-world mass of the car allowing the jet engines to reach seriously gnarly speeds.
* StableTimeLoop: [[spoiler: Hog]] gets trapped in one after [[spoiler: Motor Ed's roadster causes them to travel back in time to 1970, where he [[IChooseToStay stays behind]] and becomes Wander, the old man he encountered at the beginning of the episode. Turns out he was being guided by himself.]]
* ThereAreNoTherapists: Averted, as Kim has been seeing one for several months. Not that she's very receptive to it, mind.
* YoungerThanTheyLook: Happens to [[spoiler: Bonnie against her will when [=DNAmy=] artificially ages her to about 70 years old, in order to use her as a test subject for a de-aging drug commissioned by Shego.]]
