WMG / The Adventures of Jimmy Neutron, Boy Genius

The Jimmy Neutron-franchise takes place in the same universe as Back at the Barnyard (and its Pilot Movie).

Jimmy made Goddard because his parents wouldn't let him have a puppy

It makes sense, since he made his robot brother Bro-bot when his parents said they weren't ready to have another kid. Maybe at one point a few years before the series, he asked them for a puppy, but they said no (didn't think Jimmy would be responsible, one of them was allergic, etc)so he decided if he can't have a dog, he could make one instead.

Genius Sheen knew his Brain would explode

He was smarter than Jimmy and was able to read minds. He also seemed to have some reality manipulation abilities meaning he could've have adapted past that point.

The reason Jimmy's father acts rather dim is almost certainly because he caused himself brain damage by smoking weed.

Let's start with the question of how a boy as smart as Jimmy could have a dad as dumb as Hugh. It's genetically impossible, right? Well, maybe it would be impossible if you believed that Lamarck Was Right. But we know that Hugh could have an acquired condition that made him dumb, but still had smart genes to pass on to Jimmy.

Still not convinced? Well, I refer you to the episode where Jimmy time-travels back to the time when his father proposed to his mother in the seventies. Jimmy's mom called him by the nickname "Hughby-Dooby." 'Nuff said.

And this may not be relevant, but notice that there's only one letter of difference between "Hugh" and "High."

• Most subtle Drugs Are Bad message ever. This also explains his obsession with ducks to the point of Cloud Cuckoolander.
• It's hardly "genetically impossible." Unlikely, yes, but human intelligence— inasmuch as we even have a semi-clear definition of just what that quality is— is determined by a myriad of interacting genetic and environmental factors. Plenty of room for a high IQ to skip a generation.
  • Also it was implied on the episode "Clash of the Cousins" that the Neutrons have "dominant genes" for stupidity and obsessiveness and Stupidity (Hugh was fortunate enough to get both his love for ducks and low IQ respectively. Jimmy and Eddie inherited the rare Neutron "genius gene".

Beautiful Gorgeous writes ZADR fan fics in her off-time.

"You're so brave and cute for such a green guy." After that one line, she grew an infatuation with him and things went bad.

Jimmy's Mom is just as intelligent as he is

She even studied at college but gave it up for - guess who - Hugh. And pie-baking. She has often shown sudden outbursts of scientific knowledge, that even rival Jimmy's.

• Since the show is set in a city that seems to have stopped at the 50's, it'd make sense. Mainly because she'd be poorly-viewed by others if she opted for a career instead of being a housewife.
• So that's where Jimmy got his intelligence from. Maybe Jimmy's mom's side of the family are all intelligent.

Johnny Quasar is Jimmy Neutron's grandfather.

Combined with the above WMG, it seems highly plausible that Jimmy Neutron got his intelligence from his mother Judy, who got it from her father Johnny Quasar.

The "dumbing down"-helmet left Jimmy unable to stave off Hollywood Science and Aesop Amnesia

Alternatively, it has an area effect, leaving everybody unable to Think Of The Potential if they'd just repair the flaws of the Black Box.

Jimmy killed the blimp pilot in the election episode.

The three candidates were disqualified due to being guilty of blackmail, fraud, and murder- no, wait, operating a blimp on school grounds. Mrs. Fowl didn't want to cause a panick, and Jimmy used his hypno-ray to erase the information from any witnesses' minds. Alternately, goat-kebab boy was guilty of murder, and Mrs. Fowl disqualified Jimmy instead so as not to incure his wrath.

Sheen is an experiment gone wrong by Jimmy.

In one episode, Sheen pretended to be the genius in order to impress someone, and says that Jimmy was a failed experiment. Could the reverse be true? (Also, I don't recall ever seeing his parents.)

• Actually, you do get to see Sheen's dad: Both in the end of The Movie ("Ultra-Dad!" "Ultra-Son!") and in the made-for-tv movie where the kids have to compete in an intergalatic reality show; he's in the group of parents that's rigging the portal on Earth to try and get the kids back home.
  • And also a couple other episodes. He apparently works as some sort of mechanic.
    • Air-conditioner repairman.
    • Sheen's dad is even the focus of one episode and briefly becomes a superhero to impress Sheen.
• Adoption solves everything.

Jimmy is a Genius.

Carl and Sheen are his Beholden, and the reason everything he invents goes awry/berserk is because of Havoc. The reason he doesn't display typical Genius behavior is that he's unaware of other Genii in the world.

Jimmy will grow up to become a spy in the future

The episodes featuring Jet Fusion and Professor Calamitus are clues.

Jimmy will grow up to bring The End of the World as We Know It, a Dystopia, or will just stop inventing altogether

Almost every episodes are a clue. Jimmy's inventions bring much more chaos than the satisfaction of the people. His inventions seem much more immoral to the masses. So Jimmy's fate has two choices: either to stop inventing and do not contribute to the progress of the world, or, he would just keep on inventing and bring chaos and destruction.

• The episode where Libby becomes a dictator in the future is a clue. The original timeline where Jimmy keeps on inventing is not actually a utopia: it is a Crapsaccharine World where Jimmy rules a scientific dictatorship. In the timeline where Jimmy stops being a genius, his nonexistence causes a power vaccum where a Cleopatra-lookalike named Libby takes over.
  • That sounds like The Ultimate Enemy" episodes in Danny Phantom.
• Jimmy grows up to become Flint Lockwood.
• Let's also remember, Jimmy was able to enslave the school to his whims. With candy. If you think that's scary, just wait till he dives into something even more addictive, like drugs. The human race would only have a matter of time.

Hilgo from "Time is Money" is Cindy in that future.

Being so rich, Judy and Hugh Neutron bought Retroville, leaving everyone else in the town extremely poor. Cindy grew depressed and slowly became.... that, and forgot how to speak. Except for the simple grunt "Da!". Hugh, to humor her, gave her a job as Jimmy's ugly, maid, nanny, THING.

• ...Wouldn't Cindy still be the same age as Jimmy, since it's the alternate PRESENT, not FUTURE Hilgo is in?

Jimmy Neutron has a itty-bitty bit of Klingon in him.

Due to his large head, all he is missing is the ridges, dark skin, scary teeth, and the other Klingon traits. Sadly, his heart is not Klingon, for he thinks like a Vulcan.

Mc Spanky's is an actual burger, like one that would be eaten by a real-world human

Nicktoons Unite! has him interact with SpongeBob. The Movie shows SpongeBob to be very small. So there.

• This extends to the Lollipop on top of the Candy Bar, and any and all other giant inanimate objects in the series as well.

Jimmy Neutron will grow up to be Howard Wolowitz.

Why not?

• Alternatively, Sheen Estevez becomes Howard Wolowitz. His enjoyment of catfights certainly lends credit to the idea.

Cindy is a child of Athena

If we're going by the Percy Jackson continuity, Cindy fits the description of an Athenian to a T. Not to mention she does Tai Chi, a form of martial arts used for battle, she's highly intelligent, exhibits hubris, has many talents in building things, and we never get to see how she spends her summers. The only reason her grades are lower than Jimmy's is because of the ADHD and dyslexia that demigods naturally have.

The Evil Clone planet wasn't actually destroyed.

It just looked like it did, instead, it was teleported into an alternate universe where everyone is a doll. The inhabitants began making evil versions of every other living person. Jimmy was forced to have a doctor he knew monitor them, and make sure they didn't try anything funny. Unfortunately, the doc went mad, and soon he grabbed a chicken from the side of the road to watch the folks because he didn't care anymore.

Jimmy still has a bit of hamster left in him after the incident with trading bodies with the hamster.

Jimmy is actually evil

He causes most of the problems in the show. Being the genius that he is, he could foresee any potential issues (or at least have the sense to run tests beforehand). There's an episode where he modifies a restaurant and it ends up flying and melting all other food sources in Retroville. So, yeah, Jimmy deliberately causes most of the problems in the show, so he can be set up as the hero.

• He's a genius with the mentality of any other child his age.

The embarrassing bubble picture is from an unmade crossover with SpongeBob SquarePants.

In one episode, they briefly saw a pineapple at the bottom of the ocean. Off camera, they must have investigated. Somehow, perhaps with a shrinking device, they went inside. From there, they shared an embarrassing joint freak-out (The cliched "AAH!" "AHH!" See Flushed Away's first trailer for an example.) scene. Somehow, a photo was taken. That photo is the embarrassing scene from Spongebob's Christmas party AND the embarrassing bubble picture from Jimmy Neutron. Fridge Brilliance, anyone?

• Or maybe it could be just Carl burping out bubbles after consuming bubble liquid, mistaking it for a soft drink
  • Also, on a side note, the "AAH!" "AAH!" thing is called Reactive Continuous Scream.

Judie makes a sexual reference.

In the episode where Jimmy's grandma is introduced. Hugh puts stuff in the car for his romantic getaway with Judie. Judie tells him to be careful because he won't be used to her rearranging the furniture if he broke his back. By rearranging the furniture, she meant sex.

• Methinks you're half right; as pointed out on the Radar page, the bit about rearranging the furniture is only said after Jimmy walks into the room. She could have tacked it on at the last minute to prevent Jimmy from connecting the dots.

Jimmy's parents eventually end up having another baby

• I imagine that Hugh and Judy would end up being a girl, whose full name would be Beatrix Eleanor Neutron, while calling her "Trixie" for short ("Beatrix" coming from Beatrix Potter and "Eleanor" coming from Eleanor Roosevelt). I imagine Trixie becoming just as intelligent as her brother while having more common sense and better social skills, but also looking up to her brother as a role model and the two of them having a very close sibling-relationship.

Their will eventually be a season 4

• It was once planned, but was shortly canceled due to the lackluster box office performance of The Ant Bully.

This universe's version of Thomas Edison got along with Nikola Tesla.

• It can seem quite odd that someone as bright as Jimmy would admire Edison, who was more a businessman and entrepreneur than an inventor, and never mention Tesla at all, whose aspirations were much closer to Jimmy's than Edison's. When Edison DID eventually appear in the series, he turned out to be a lot nicer and friendlier than the real Edison. Hence, it is very possible that the real-life rivalry between Edison and Tesla never materialized in the Jimmy Neutron universe, and the two of them shared inventions and knowledge with each other, or at least that Tesla invented things while Edison sold and marketed them with Tesla content knowing his inventions are helping the world, which would've led to Edison having a much higher profile than Tesla. Alternatively...

This universe's version of Thomas Edison successfully shut Nikola Tesla out of the public eye completely.

• Which is why Tesla is never mentioned even once in the entire duration of the TV show even though his contributions to society as a whole are present: Edison managed to take credit for everything Tesla did and erased Tesla from the records. If this is true, then the friendly, jolly nature Edison puts up in the series is either a façade or he's friendly specifically to Jimmy but not Tesla.

If the show is revived they will just ignore Planet Sheen

Or Sheen's escape from Zeenu will be briefly brought up as a Noodle Incident and never mentioned again.

• A theory posted on the Planet Sheen WMG that the series is all in Sheen's head (as he made it up, like a story from his imagination).

The reason we never see Sheen's mom is that his parents are separated

• We've heard about his mom and little sister a few times but they're never shown. So my theory is that his parents got divorced, and that his sister lives with their mother.
  • Word of God claims that Sheen's mom died when he was too young to really remember her.

Professor Calamitous is Jimmy's grandfather and Judy's biological father

We already know calamitous was married at one point and had a daughter, so it's not strange to assume he had more then one child. Although, he may have had Judy with another woman out of wedlock. We literary know nothing about Judy's parents, so for all we know, she might have been raised by a single mother, not knowing her father was a mad scientist. who's mad scientist genes she would be passing on to her son Jimmy.

The show takes place in the same universe as Pet Alien

Mostly because they're both 3D-animated shows that aired in the mid-2000s and feature aliens.

Cindy is adopted

Genetically, her blond hair and green eyes make no sense if Mr. and Mrs. Vortex are her biological parents. Neither of them have blond hair and her father's brown eye genes would have dominated her mother's green eye genes.
