Project Dark Jade is a fan collaboration project on Fanfiction.net for fans of Jackie Chan Adventures.Conceived by Eduard Kassel and Nocturne no Kitsune (the latter of which later dropped out of sight), the general idea came around when the two discussed the lack of stories on FFN exploring the concept of the Queen of the Shadowkhan, the one-time Super-Powered Evil Side of JCA core cast member Jade Chan, and perhaps the biggest Ensemble Darkhorse of the series. Eventually coming up with what they felt were viable story ideas based on the Queen's presence, they set out to write them in the hopes of inspiring others to similarly write stories exploring the idea of Jade somehow going over to The Dark Side. And while Nocturne has long since dropped off the radar, the popularity of Eduard's stories (especially Queen Of All Oni, which is possibly the most popular JCA fic of all time, as it is the top JCA fic in favories, follows, and reviews) has continued to have the desired effect of inspiring other authors to write their own stories.
Ages Of Shadow by Eduard Kassel: Years after falling to the darkness, Jade Chan has finally been defeated by the J-Team and their allies; and been banished. In defeat and isolation, Jade must face a challenge like nothing she has ever encountered before. What lies in wait for the fallen hero in the millennia that stretch before her? What shall she loose and what will she become, in the Ages of Shadow? In-progress.
Her Shadowed Realm (Crossover — Yu-Gi-Oh!) by CryptIXeeper: A different take on the theme, it is set long after Jade's fall to darkness and banishment to the Shadow Realm. Now calling herself Yu, she reaches out into another universe in the hope of freeing herself, by cutting a deal with a certain millionaire reviving an ancient Egyptian game... On hiatus.
Jade Cobra by balfang von claude: (Crossover — G.I. Joe; Recursive Fanfiction of A MAD Heir) Cobra Commander has his eyes on Jade Chan and plans a rescue when Jade is about to be kidnapped by Dr. Claw to earn her favor, and offers her a great position as General of San Fransisco headquarters being based at the former Dark Hand's HQ. How will Jackie react when he finds Jade months later, and how can the Joes defeat a leader who is also a child? It is in progress.
Jade Dragon by Eduard Kassel: Shortly after the event's of the canon Grand Finale, a mysterious being uses a magic mirror to cause Jade and Shendu to switch lives. Jade now finds herself reliving the events of the series as Fei Cui Huo, the Jade Dragon, the Demon Sorceress of Fire, desperate to find a way to regain her own life. On hiatus.
Kage (Crossover — W.I.T.C.H.) by chaotic9: During the final moments of canon's Grand Finale, a spiteful Drago casts a spell that not only banishes Jade to another universe, but reawakens her Shadowkhan powers. Now stuck on Meridian, a bad first encounter with the Guardians and the manipulations of Nerissa finds Jade forced to serve as one of the sorceress' Knights of Vengeance. Now she has to find a way home without getting killed, all while dealing with the growing influence of the Queen, who wishes to assume complete control of her body and mind. It is in-progress.
Queen Of All Oni by Eduard Kassel: An alternate take on Season 4 of the show, where Daolon Wong's botched spell, rather than releasing Tarakudo from his imprisonment, instead turns Jade back into the Queen of the Shadowkhan. The race for the Oni masks is now on, but with the added stress of the heroes having to find a way to return Jade to normal before she is lost to the darkness forever. It is in-progress.
Queen Of Shadows originally by Nocturne no Kitsune, adopted by Eduard Kassel: During the fight with the Shendu-possessed Jackie, the Book of Ages is damaged, altering reality beyond Shendu's control. Jade awakes to find herself in a new world, as Queen of a Shadowkhan empire slowly conquering Feudal Japan. Now she has to find a way to return home, while navigating the politics of the Shadowkhan and dealing with the forces of Light that want her dead. It is in-progress.
A Shadow Of The Titans (Crossover — Teen Titans) by Eduard Kassel: Following an offscreen battle with a demon, Jade finds herself banished along with it, ending up in a weird pocket dimension. Encountering a being called The Cackler, he transforms her back into a Shadowkhan before tossing her into the TT universe, where she's quickly drafted by the HIVE. Now forced to act like a villain so she won't get killed, Jade has to contend with both her fellow villains and the Teen Titans while trying desperately to find a way home and back to normal before she undergoes a Split Personality Merge with the Queen. It is in-progress. According to Word of God, it's the first of a planned trilogy.
Shadows Awakening by Ander Arias: Another alternate take on Season 4. An encounter with Daolon Wong, who's using an ancient artifact to restore his lost powers, gives Jade the ability to use her Shadowkhan abilities. Now the J-Team has to stop Wong, who's being guided by Tarakudo's predecessor as ruler of the Shadowkhan, if they're to have any hope of saving Jade from succumbing to her darker nature. It is complete.
Webwork: Balance does not discriminate. The failure of successive dark champions present and future has created an imbalance in favor of the light. Thanks to the meddling of a fallen foe, Jade Chan will pay the price for another's tampering with destiny. Though heroes will rise yet again to face darkness, Jade has a stake in this conflict such as no dark foe before her. Post Season 5. In-progress.
Stories without pages of their own
When I Grow Up by Eduard Kassel: A mystic clock sends Jade into the future (again), only to find her future is no longer as bright as she had hoped. Oneshot.
Roommate by ppH: Shendu possesses Jade instead of Valmont. Will she be able to resist his influence, or will he drag her down into the darkness. On hiatus.
The Blue Knight and the Dark Queen (Crossover — Sonic and the Dark Knight) by D. J. Scales: Tarakudo changes Jade back into the Queen during their first encounter. In order to counter this new advantage for the dark forces, Uncle summons a pair of heroes to help the J-Team. Namely a certain hedgehog, his two-tailed friend, and a talking sword. It is complete.
Queen's Ascension by DigitalHazared (later adopted by sub phantom): When the Oni masks are shattered, rather than releasing the Generals, all of their power is transferred to Jade. Now she finds herself as the new Queen of the Shadowkhan, with her future uncertain. On hiatus.
Demon Sorceress of Fire by Mengskhunter: By killing Shendu, Jade has inherited his power and position. Threatened with eternal torment, she now sets off to free the other Demon Sorcerers, in the hopes of both protecting her family from what she's becoming, and hoping that the other demons will stop Shendu's mind from overwriting her own. It is in progress.
A MAD Heir (Crossover — Inspector Gadget) by Vladimir Zhivanevskaya: Jade is kidnapped by Dr. Claw, who has his scientists wipe her memories and brainwash her into being a MAD agent. Now, years later, Jade is MAD's greatest assassin, and is about to come face-to-face with her forgotten past. It is in progress.

Now the heroes have to deal with an Enemy Civil War among the Shadowkhan. On hiatus.
Age of Demons by jameygamer: Shendu is able to successfully alter the Book of Ages without complications. In this new reality where Shendu rules his fellow demons as well as the humans, a Jade Chan with no knowledge of her true nature is chosen by the banished Tso Lan to be the new recipient of his powers, beginning a war for domination among the Demon Sorcerers. It is in progress.
The Tenth Tribe by hamishwarfare: Jade learns to summon her own tribe of Shadowkhan. On Hiatus.
The March of the Black Queen: Through the changing years, Jade is now a shadow of her former self. A victim of her frustrations and embodiments of anger; a dormant evil now lies awake within her, consuming and transforming her into the Queen of the Shadow Khan once again. The struggle between darkness and light just began. In-progress.
Talismans and Wu: Jackie Chan blows up the talismans, unfortunately Jade was in the way. Meanwhile in another world, Jack Spicer has created a machine to collect all the Wu of the world. Things don't go exactly as planned, not only the machine blows up, but Jade ends in the Xiaolin Showdown world.
Alternate Timeline: As For Want of a Nail states, a number of stories follow the canon timeline (more or less) up to a point before the plots diverge (usually around the start of season 4). For example, Kage diverges from JCA canon during the last moments of the Grand Finale.
Dead Fic: Several stories have been on hiatus for a while.
Queen of Shadows is an odd example. The original version stopped when Nocturne went missing, but Eduard has all of his friend's story notes and so after a period of silence on Nocturne's part, has continued the story under the subtitle A Tale Across Ages.
Evil Costume Switch: Usually, though what exactly Jade changes into varies from story to story. The ninja clothes the Shinobi Tribe wears are a popular choice.
Evil Versus Evil: In most of the stories Jade becomes becomes evil, but aside from Jackie and the heroes she also ends up fighting against another villain, usually one of the series' Big Bads, or in the case of the crossovers, sometimes the local villains.
Extreme Omnivore: Since Jade was already a Big Eater in canon, some writers expand on this and make her being able to eat almost anything, mostly to make her more inhuman.
Fallen Hero: Jade in every story is either already one, or is at risk of becoming one.
Fandom Specific Plot: Most of the stories follow the same pattern: Something causes Jade to turn back into the Queen of Shadowkhan, who aims for some nefarious goal, usually gaining more power, or getting back at Jackie and the others for some reason. Thanks to the Project, this kind of stories have become quite popular among the fans (though not as much as the ever-present shipping fics).
For Want of a Nail: Many of the divergent points are small "What If?" scenarios, with varying levels of how large the changes are.
In Spite of a Nail: Stories tend to have things happen nearly the same as canon in most cases, depending on the amount of initial changes.
The two The Blue Knight and the Dark Queen stories are especially notably, in that despite Jade being evil and getting magically aged up into an adult, and the presence of Team Sonic, nearly everything happens exactly the same.
Superpowered Evil Side: Pretty much most of the stories focus on Jade becoming the Queen of the Shadowkhan again.
Super Senses: In certain stories Jade gains enhanced senses.
The Chosen One: In March of The Black Queen, it is implied Jade is destined to rule the world as the Shadowkhan queen.
Tomboy Princess: In most of these fics Jade retains her tomboyish nature. Though it comes to be an inconvenience in Queen Of Shadows since as Queen of the empire she is expected to act with decorum and femininity, and isn't even allowed to train since she has men to do her fighting for her.
Took a Level in Badass: In all the stories, Jade becomes significantly more powerful and skilled in magic, martial arts, or both!
Vague Age: Jade's age is something the PDJ writers seem to never agree on, due to the fact that it was never revealed in the show. Depending on the story, her age varies from eight to twelve.
Though it can be older if the story takes place after the series.
Worth It: In several of the stories Jade claims this despite the hell she has to go through for her new powers.
Wrong Genre Savvy: In 'March of the Black Queen' Uncle casts a spell to see where Jade is and finds her in a building with roman architecture. Jackie guesses she would either be in a bank or a library, and given that no other supernatural villain in the past has ever valued money assumes she'd be in a library looking for a rare magic book. Jade is in fact at a bank robbing the place blind.
Subverted when Viper suggests she is in a bank, and while Jackie and Tohru stare at her like she spouted nonsense Uncle concludes she is probably right.
