[[http://www.fanfiction.net/s/3564181/1/The-Other-Side-of-Tomorrow ''The Other Side of Tomorrow'']] is a ''{{The Adventures of Jimmy Neutron}}'' fanfic by Mara S., owner of the JN fansite IDreamofJimmy.

When experimenting with teleportation technology, Jimmy uses it on [[TheRival Cindy]] for laughs. But of course, something ends up going wrong and Cindy ends up getting teleported to an AlternateUniverse with Jimmy, Carl, Sheen, Libby, and Goddard tagging along. What kind of universe they end up in is not what they expected, as it turns out, it's a universe set fifteen years in the future of their own. They meet Cindy's future self, Aurora, and April the Gorlock who explain that they are part of an intergalactic war against a mad dictator bent on controlling the entire galaxy. They also learn that this all stemmed from Libby's 12th birthday party when she was given Jimmy's Megalomanium as a gift by mistake (from the ep "The Tomorrow Boys") only she wasn't the one exposed this time. It was Jimmy himself.

While originated on nick.com, it eventually moved full-time to the author's website IDreamofJimmy, and was even posted on fanfiction.net. It has everything, Action, Suspense, Comedy, non-squicky romance, and enough {{CallBack}}s and {{ContinuityNod}}s 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 OCs. If you're a fan of Jimmy Neutron, do yourself a favor and read this. It's assuring you won't be disappointed.

The story is now complete. It even has its own "ExpandedUniverse" on [[http://www.fanfiction.net/s/7162674/1/TOSOT-Oneshots fanfiction.net]] if you're into that sort of thing.

----
Tropes:
* AcePilot: Aurora
* ActionGirl: April and Aurora
* AirVentPassageway: The heroes use them to break ''into'' the base and they are filled with moving water.
* AlienLunch: April's delicacy, Tek nok shii-len
* AlienSky: The Desert Planet from Chapter 6, which has multiple suns, and Planet Gorlock, which has a crimson-tinted sky.
* AliensSpeakingEnglish: Can't really be helped, since the original series did this.
* TheAlliance: Gorlock High Council and its allies.
* AllMonksKnowKungFu: Established in the actual series, though some attempt was made to play up the Asian character of Shangri Llama.
* AlternateHistory: beginning with Libby's 12th birthday party
* AlternateUniverse: Self explanatory. This trope isn't played wholly straight, however, since the gang from the original universe stays intact and in character, but end up as spectators/participants in another universe.
* AnywhereButTheirLips: Future Sheen and Future Libby. Sorry.
* AppliedPhlebotinum: most of the technology, especially anything made by Jimmy. "Why does it work? Because it's SCIENCE!"
* ArchEnemy: Aurora and DJ, though she views their rivalry to be more significant than he does.
* ArrangedMarriage: Future Libby and Future Sheen; subverted by the fact that they actually had romantic inclinations anyway.
* ArtEvolution: Mara, the author, has gotten better at drawing in the years the story has gone on.
* TheAtoner: There is some indication that [[spoiler: Future Jimmy]] will become this after [[spoiler: he's cured]].
* {{Badass}}: Practically everyone.
* BadassLongCoat: Nav
* BadassNormal: April, most notably.
* BeastAndBeauty: Future Sheen and Future Libby, with a twist
* BerserkButton: Dictator Jimmy is a master at pushing all of Aurora's.
* BetaCouple: April and Nav. Arguably, also Future Sheen and Future Libby, although theirs is more of an actual ''romance'' than the main couple, who lurk somewhere in {{Masochism Tango}} {{Belligerent Sexual Tension}} {{Almost Kiss}} {{Foe Yay}} territory. Also, the romance between the kids, which is treated like something that might actually happen between kids, i.e. nothing excessive.
* BigBad: Dictator Jimmy
* BlindSeer: Tuyen
* BrokenBird: Aurora.
* CasualDangerDialogue: All over the place, although Nav and April particularly enjoy flaunting this trope.
* TheChessmaster: Dictator Jimmy
* TheChick: Future Libby, to an extent.
* TheChosenOne: both Sheen and Future Sheen, as far as the Monks of Shangri Llama are concerned. This is, of course, a holdover from the show.
* CliffHanger: Mwa. Mwahahaha.
* CollectiveGroan: Numerous times, especially among the kids
* ContinuityNod: A crapload, especially to "The Tomorrow Boys", "Win, Lose and Kaboom", and "Crouching Jimmy Hidden Sheen".
* CoolStarship: The Desperado, the Shahada, and the Half Life
* CorruptChurch: Numeria, according to Nav.
* CurseCutShort: Happens a lot. Then at the end there actually is a lot of swearing.
* DarkerandEdgier: Full stop. Although, to be fair, the fic simply takes the relationships between the characters and the tone of the original show to their logical extremes.
* DarkAndTroubledPast: all the kids, after Jimmy gets exposed to the megalomanium.
* DeadpanSnarker: The characters take turns, but Cindy fills this role more often than not.
* DeathIsDramatic: [[spoiler: Nav's final scene, anyone?]]
* DistressedDamsel: Future Libby, very, very briefly after she is accosted by DJ and thrown in FS's prison cell. Though, considering the circumstances, she behaved rather admirably.
* DoubleEntendre: so many, many things.
* DreamingOfThingsToCome: Tuyen's future-forecasting ability; Jimmy's dream in "Suffer the Fate of Atlantis" is another example of this.
* DumbassHasAPoint: Sheen, when he suggests that they should use Jimmy's Air Gum to aid in their impending infiltration of DJ's base.
* EmotionalTorque: Taken to a literal extreme in [[CrowningMomentOfFunny the Emotion Rooms.]]
* MrFanservice: Nav. His fangirl following is notorious. Also DJ and Future Sheen, if you're into that sorta thing.
* EvilVersusEvil: Criminals fighting...well, more criminals. The main bad guy is one of the seven most wanted criminals in the galaxy, and so is one of the main good guys. Go figure.
* FamousLastWords: [[spoiler: By Nav. "Say hi to Aurora for me when she's kicking your ass."]]
* FanService: Face it. It happens.
* FasterThanLightTravel: a staple of all good space fiction; in this case it takes the form of the Hyperdrive. This goes hand in hand with inertialdampeners.
* FightingFromTheInside: [[spoiler: Dictator Jimmy, as it turns out. So much so that his non-megalomanium side was involved in a decade-long BatmanGambit against his evil side. Too bad it didn't work...]]
* FluffyTheTerrible: April's pet Loof-loof.
* FutureMeScaresMe: Jimmy and his future self.
* GadgeteerGenius: Jimmy.
* GenreSavvy: Nav, Nav, Nav. He's even a {{Star Wars}} fan.
** DangerouslyGenreSavvy: DJ is a particularly ruthless example of this trope, though he indulges in some good ol' fashioned {{evil gloating}} when around Aurora. Nav eats this trope for breakfast.
* GettingCrapPastTheRadar: Back when it was on nick.com, that was practically the goal of this fanfic.
* {{Foreshadowing}}: It's there, sometimes to FridgeBrilliance levels.
* GlowingEyesOfDoom: Future Sheen's left eye, when he's being all BrainwashedAndCrazy
* TheGunslinger: April and Nav, both probably falling under type B.
* GreenSkinnedSpaceBabe: April (Nav ''scored''.)
* HandCannon: April's one true love.
* HeelFaceTurn: [[spoiler: Future Carl]]. Although he does specifically say that he only changed sides because [[spoiler: the kids weren't going to harm Dictator Jimmy, only cure him]].
* HeroicBSOD: Aurora almost has one of these when she sees that [[spoiler: her copy of the antidote has been destroyed]], though she quickly suppresses it.
* HollywoodCyborg: Nav
* TheIgor: Future Carl
* IKnowYoureInThereSomewhereFight: an interesting inversion, since the villain uses this against the protagonist in order to weaken her resolve.
* ImportantHaircut: Averted. Aurora asks Future Libby to cut off all of her hair after it gets singed during her battle with DJ. But Future Libby refuses and instead gives her a small trim.
* IWantMyBelovedToBeHappy: The reason why Lee is willing to accept April's engagement to Nav despite the fact that he is in love with her also.
* KilledOffForReal: [[spoiler: Nav, Future Goddard, and Aurora. She gets better, although at great personal cost]]
* {{La Resistance}}: The rebels. Partially subverted in that they are not a {{ragtag bunch of misfits}}, but rather a dangerous and influential criminal organization that the Galactic Law Enforcement won't even touch.
* LatexSpaceSuit: Aurora. And DJ. Haha.
* LoveableRogue: Nav
* LoveAtFirstPunch: Nav with Aurora, though it's one-sided and in the past. Sort of.
* LoveTriangle: April, Nav and Lee. Arguably DJ-Aurora-Nav as well.
* ManipulativeBastard: Dictator Jimmy, to a T.
* MaskPower: Aurora's silver mask, though she uses it to cover up vulnerabilities, not just because she's a very powerful character.
* MechaMooks: DJ's creepy-crawly robot guards, though the trope is averted by the fact that they are actually quite dangerous (one almost gets Nav).
* MyFutureSelfAndMe: pretty much the whole point of the fanfic.
* OldMaster: Chen-Yu.
* PairTheSpares: [[spoiler:WordOfGod says that Future Carl hooks up with Nav's little sister Laudya afterward.]]
* PaterFamilicide: Inverted. The father isn't the one killing his family; rather it's the son who kills his parents (and practically everyone else on Earth).
* ThePowerOfLove: subverted since, [[spoiler:Future Libby didn't beat Future Sheen with any of that "Power of Love crap", but rather by smacking him over the head with a chunk of metal. Although, to be fair, he only let his guard down because he loved her, so...]]
* ProudWarriorRaceGuy: Or girl- April.
* TheReasonYouSuckSpeech: [[spoiler: Dictator Jimmy to Aurora, and vice versa. He does a better job]]
* RedemptionEqualsDeath: [[spoiler: Future Jimmy tries to commit suicide after he is cured of the megalomanium. But Aurora will not have it.]]
* RuleOfCool
* SayMyName: A rather chilling example between DJ and Aurora, used to reinforce their 'old rivals' relationship before they start their current conflict.
* ShoutOut: Nav makes a ''ton of these to go with his DangerouslyGenreSavvy nature.
* SlidingScaleOfSillinessVersusSeriousness: switches from cheesy jokes to {{serious business}}, sometimes in the same chapter. Whether or not this is MoodWhiplash will depend on your point of view.
* SmiteMeOhMightySmiter: Aurora has one of these after her ship gets damaged above P24-505.
* SpaceDoesNotWorkThatWay: Shut up, yes it does!
* SpaceClothes: Brought to life spectacularly in volume 2, when Aurora and Libby go shopping for spacesuits.
* SpockSpeak: All the Gorlocks, but especially April.
* StuffBlowingUp: Loves this to death.
* SupernaturalMartialArts: Justified because of those crazy high-tech combat suits.
* {{Subtext}}: Dear God. This fanfic could probably be renamed "subtext", there's so much of it.
* TagalongKid(s): The Kids, subverted as they are the main characters at first.
* TechnoBabble: Practically every other sentence that leaves Jimmy's mouth.
* ThatManIsDead: Aurora refuses to go by her first name, Cindy. It becomes SeriousBusiness when the Dictator refers to her as such.
* TimeTravel: time passes more quickly in the alternate universe (by a minuscule amount), resulting in a 10 year gap between the 2 universes.
* TortureCellar: DJ's underground prison cells.
* {{Tragedy}}: TOSOT has elements of this, though the plot is not strictly a tragedy. Aurora can be classified as a tragic character, however, since her current position is the result of her own actions (spraying the megalomanium in Jimmy's face)
* {{Tsundere}}: Cindy
* UnderwaterBase DJ's {{villainous lair}} on P24-505.
* UnluckyChildhoodFriend: Poor, poor Lee. [[spoiler: WordOfGod says he eventually becomes a {{victorious childhood friend}}]]
* UnresolvedSexualTension: need I explain?
* VillainTeamUp: The Gorlock High Council
* {{Wanted Poster}} Aurora keeps one of herself in her own room.
* WellIntentionedExtremist: Nav, who has admitted to acts of terrorism on his own planet because he doesn't approve of the {{corrupt church}} that rules it.
* WhichMe: happens a lot, and is the reason for the awkward naming ("Future so-and-so")
* WouldNotHitAGirl: Nav will not harm women or children, despite being a murderous thief. Averted with DJ.
