Possibility Engine

POSSIBILITY ENGINE is a fanfic that takes the premise of Sliders and applies it to Kim Possible. The story begins with one of Drakken's devices malfunctioning and ends with the first battle in an interdimensional war. Throughout it all, Kim and Shego form an uneasy alliance as they jump from world to world trying to find their way back home.

The story is notable for making dimensional travel accessible and easy to understand, while still engaging in a level of pseudo-scientific Techno Babble that's enough to keep any Speculative Fiction fan interested (one of the chapters is, in fact, called "Technobabble"). The author is very good at conveying the sense of shared isolation that would naturally result from an interdimensional journey, while still hinting at grander things and building an obscenely complicated plot that requires multiple readings to understand.

There is a sequel, called The Demon of Go City, that unfortunately hasn't been updated in a while. It has also spawned two side stories, Contagion and The LAST Thing You Wanted to Read, the former of which ties the series into the author's Disappearing Doctor Universe, while the latter is a non-canon "what if" scenario in which Ron has somehow become  All are very much worth checking out.

This Fanfic provides examples of:

 * AI Is a Crapshoot: Pentos/Athena. Played with, since she becomes a lot more confident and able to think for herself, but still remains fanatically devoted to The Grand Commander and his wishes.
 * All the Myriad Ways: Averted, since the events of each world leave a lasting impact on Kim and Shego.
 * Armor Piercing Question: When  gives his Motive Rant near the end of "Slow Collapse," Kim reveals herself and asks him: "Is that why you're doing this,  ?" The shock of seeing her and realizing he was wrong completely breaks his resolve.
 * The Atoner: While she doesn't execute a full Heel Face Turn, Shego's experience in the first world leads her to not be so reckless as the version of her that created such a hell.
 * Bittersweet Ending: Let's see:  On the other hand, Shego is now more determined than ever to get Kim back, and the story ends with
 * Chekhov's Gunman: Fayt,
 * Cold Blooded Torture:  is on the receiving end of this in the first world they go to, since   The experience sticks with her for the rest of the story.
 * Cold Open: A couple of the chapters have a short scene before the title is revealed.
 * Create Your Own Villain: Shego unwittingly inspires Pentos--a shy, demure AI who only wishes to serve The Grand Commander--to become Athena, an evil, sadistic, power-hungry bitch.
 * Deadpan Snarker: Shego, of course.
 * Enemy Mine: Kim and Shego for most of the story.
 * Facial Dialogue: Though she does know how to use words, this is primarily how Cassie communicates with Shego. Dr. Kim and Ron even lampshade it at one point.
 * Grand Theft Me: Athena does this to, downloading herself into her brain.
 * Meaningful Name: The Grand Commander's AIs are all named after figures of Greek mythology.
 * Zelus is the personification of dedication and emulation.
 * Asclepius was the demigod in charge of medicine and healing, an appropriate moniker for the AI in charge of The Grand Commander's health.
 * Cratos was the personification of strength (no, not that Kratos--he was actually a demigod), which is a fitting name for The Grand Commander's head of security.
 * Prometheus is well known as an immortal who brought fire to the mortals, and was imprisoned by the aforementioned Cratos at the behest of Zeus as punishment. This is actually a clue, since
 * Athena was born when Zeus ate one of his mistresses (no, really) and she burst fully formed out of his forehead, making her literally Zeus' brainchild, which is fitting for an AI. She was also the Goddess of Wisdom and Defensive Warfare, which makes her name somewhat ironic as well considering this Athena's actions.
 * Reality Bleed: Drakken's plan at the beginning is to use the Pan Dimensional Vortex Inducer to find a reality in which he was able to conquer the world, then use a device called a Dimensional Drill to let that reality invade this one. It doesn't work.
 * Ridiculously Human Robots: The MFRs.
 * Self Fulfilling Prophecy: The Grand Commander's dimension was imprisoned by another because  Guess what he tries to do after learning this?
 * Techno Babble: This being a story about interdimensional travel, of course not everything is going to be perfectly scientifically accurate. It is, however, all internally consistent and easy to understand. Funnily enough, one of the chapters is actually called "Technobabble."
 * Villainous BSOD: Shego goes through one on the first world, when she  It continues to haunt her throughout the rest of the story.
 * Well Intentioned Extremist: Three of them, right in a row, and all with escalating levels of desperation and nastiness. M is a version of Monique who, Ron becomes Zorpox and tries to attitudinate the world after  , and The Grand Commander starts an interdimensional war over
 * Wham Episode: "Technobabble" and "War of the Worlds, Part III."
