  • Comments: Why GaDS2000's fics hadn't already been added to this page is beyond me. He is, far and away, one of the best, if not the best, Jimmy Neutron fanfic writers out there. He is one of the best fanfic writers out there, period. His characterizations are always on the spot and faithful to the show. His OCs are genuinely well-written and interesting, his plots and stories are fantastic (often incorporating genuine scientific elements alongside the more tradition pseudoscience of the show). Romance is often a major subplot to his works, but not often the central focus of his story, but even then, it is written beautifully. He's written sixteen stories, most of which get longer in length the more recent they are, but sadly, the last is a Dead Fic. Two of them are amazing crossovers with Kim Possible.

UltraMom by BekBoo20
  • Recommended by Ivory23.
  • Status: Complete
  • Pairing(s): Sheen/Libby
  • Synopsis: It's Mother's Day in Retroville...but why is Sheen so sad?
  • Comments: Explores the history behind Sheen's Missing Mom . A sweet, poignant look at a side of Sheen we rarely see. This fanfic is also being made into a manga, which can be seen here: UltraMom Comic
    • Personally, This Troper is going to have to say that while the plot was nice, it was too rushed, and would have been better off written by somebody else. — Alwaus. Roberty Mason
      • Let's take note this was her first fanfic, and she's gotten better.

Jimmy Neutron & Friends! The Quest for Sheen by Ellis97
  • Recommended by LloydNebulon.
  • Status: Complete
  • Paring(s): Jimmy/Cindy, Sheen/Libby, Nick/Brittany, Sheen/Aseefa
  • Synopsis: It's been two months since Sheen left Earth and Jimmy has reached his lowest point and nobody is the same. Now, Jimmy along with Carl, Cindy, Libby, Goddard, Nick and Brittany must go on a quest to find Sheen and bring him back home to his father, grandmother, and little sister. Along the way, they run into some old faces. First installment in Jimmy Neutron & Friends series.
  • Comments: It's a great story and well thought out. It does get heavy-handed sometimes, but it's still heartwarming, emotional and full of action. I think it's a good first installment in this new fanfic series.

The Other Side of Tomorrow by Mara S.
  • Recommended by BahamaQuadrangle.
  • Status: Complete
  • Pairing(s): NOT a pairing centered fic, but it does include Sheen/Libby, Jimmy/Cindy Angst, April/OC
  • Synopsis: After Jimmy's latest experiment in teleportation technology fails, the gang finds themselves plunged into an another universe. There, the kids meet up with the last people they expect, and slowly begin to piece together a vision of their own future far too terrible to imagine.
  • Comments: One of the few fics that features Cindy and April the Gorlock as the two lead characters, this one has it all. Action, Suspense, Comedy, non-squicky romance, and enough CallBacks and ContinuityNods to make it seem like a really epic TV movie. The characterization is spot on, and the author does a great job of creating a believable world with its own unique settings and relevant OC's. As an added bonus, the author is an excellent artist whose illustrations make the story that much better. Complete.

It's up to Jimmy and his friends to travel to Egypt and retrieve them before Professor Calamitous does - and the whole world is depending on them. But with wild desert animals, sandstorms, mummies, Jimmy and Cindy's constant rivalry, (Ultralord Stories), and just plain bad luck, how can they possibly succeed?
