Western Animation: The Adventures of Jimmy Neutron: Boy Genius
: It's a heavy burden being a man of science.
: I know what you mean, Jimmy. That's why I set out early to sabotage my highly scientific brain with cartoons and sugar.
Based on the movie Jimmy Neutron Boy Genius
, this CGI Nickelodeon series follows the adventures of Jimmy
, a preteen genius who creates inventions in his underground lab. He, his robot dog Goddard
, and fellow grade-schoolers Carl
(and occasionally extra characters like Bolbi or Betty) save Retroville/the world from invention-induced disasters just about every episode. The show lasted from July 2002 to November 2006. It is the 16th Nicktoon
, and the first to be animated using CGI.
Of interest is that the film and television series was made from consumer-grade programs. The show strains to compensate for the lack of raw technical power with very clever visuals. As per the very nature of its premise the "science" was either never explained
or clearly made up
It was a fairly successful show, running for three seasons. It was involved in a few crossovers with The Fairly Oddparents
and in later Massive Multiplayer Crossovers
in the Nicktoons Unite
series and Nicktoons MLB

. Also a recap page
A Spin-Off has been made, Planet Sheen
This series provides examples of:
- Action Mom: Jimmy's mother is incredibly athletic, coordinated, intelligent, and she keeps a plasma rifle in her utility closet (for those tough ground-in stains!)
- Adaptation Decay: Show Within a Show example; Principal Willoughby's In Name Only play "Macbeth In Space".
- Adults Are Useless:
- In the movie, this is taken to its literal extreme, There Are No Adults, when the grown-up population of Retroville is kidnapped by aliens.
- Played straight with Jimmy's dad in the TV series, who is probably one of the biggest idiots in the city.
- Inverted with Jimmy's mom.
- Aesop Amnesia: Jimmy and the main cast.
- Affably Evil: Professor Finbarr Calamitous.
- His daughter Beautiful Gorgeous inherited this from him.
- Grandma Taters counts as well.
- A.I. Is a Crapshoot: The Nanobots have a bad habit of taking Jimmy's orders to their most logical extreme. After being told to correct for errors and then (attemptedly) Logic Bombed with "humans' flaws are what make them perfect", they decide to delete humanity.
- Aliens Speaking English: Taken to quite an extreme with not only the Yolkians, but the fact there is a "galactic television lineup" with billions of channels, all in English.
- All-CGI Cartoon: Notable for being the first film and series animated entirely with off-the-shelf (as in, anyone can buy it) programs, more specifically, LightWave 3D.
- Alternate History: "Time is Money".
- Ambiguously Gay: Principal Willoughby.
- Anguished Declaration of Love: Almost. Cindy attempts this tactic to calm Hulk!Jimmy down in "The N-Men", but passes out before she can complete her confession.
- Anime Hair: Jimmy's. This is lampshaded pretty regularly.
- Area 51: Appeared in the movie. In "The N-Men", Cindy, Libby, Sheen, and Carl are taken to "Area 86" after they prove unable to control the superpowers that they developed from contact with space radiation.
- Arson, Murder, and Jaywalking: In "Jimmy for President", this is actually inverted, then played straight.
Miss Fowl: It has come to my attention that some of our candidates have been guilty of bribery, blackmail, and MURDER!! [the kids in the audience gasp] Sorry, not murder, I meant operating a zeppelin on school premises.
- In "Grumpy Young Men," the boys want to buy a violent video game that has a Media Classifications describing it as "for mature players only due to violence, exaggerated mayhem, and old lady kicking."
- Art Evolution: The animation in the series was a MAJOR improvement from the pilot. The show itself gradually improved in scope and visuals, which (as mentioned) was limited by consumer-grade software. Later episodes could be compared to the look of an hour-length drama vs. a studio sitcom, with other shows being more cinematic.
- Ascended Extra: Sheen actually had a very minor role in the movie, basically filling out Jimmy's social circle beyond Carl, only to become exceptionally popular and a much more prominent character in the show.
- Aside Glance: In "Sorry, Wrong Era", Jimmy briefly does one when Carl starts dancing calypso and singing while wearing a hula costume.
- Attack of the 50-Foot Whatever: Ms. Fowl in "Substitute Creature".
- Back Blocking:
- "Beach Party Mummy": Jimmy, Sheen, Carl, and Cindy were crowding around Libby to give her a makeover. Carl was the one mostly covering up the screen.
- "Win, Lose, and Kaboom": At one point when fighting Meldar's robot army, the camera pans over to the right until April's mother's back fills the screen. Then the camera zooms out from, Meldar's assistant, Vandana's back.
- Back-to-Back Badasses: Cindy and April in the made-for-TV-Movie "Win, Lose, or Kaboom!" There's even a scene where they run towards each other and then run up each other's feet as though running up a wall.
- Bad Future: "The Tomorrow Boys": Garbage-Surfer!Sheen, Wanted!Carl, and Loser-Married-To-Cindy!Jimmy.
- Bad Job, Worse Uniform: "Men at Work".
- Bamboo Technology: Trapped in prehistoric times because of his Dad goofing around with a time-warping device, Jimmy built a replica with wood.
- Bare Your Midriff: Betty Quinlan's Lady Macbeth costume in "Out Darn Spotlight". There is no way this would be worn in an elementary school play in real life.
- Batman Can Breathe in Space: Lampshaded in one episode, where Sheen asks how this is possible. Jimmy's explanation is not heard due to Carl singing during it.
- Belligerent Sexual Tension: Jimmy and Cindy.
- The Bermuda Triangle: One episode takes place in the "Bahama Quadrant", which Jimmy, Sheen, and Carl visit so that Jimmy can prove them that nothing supernatural is going on there. They end up finding a super villain/scientist that appears to be the cause for odd sightings and disappearances... though the ending leaves us questioning it.
- Sheen once refers to the Bermuda Triangle as the mythological North Dakota.
- Beta Couple: Sheen and Libby.
- Betty and Veronica: An unusual example. The sweeter, more mature Betty is...well, the Betty, while the edgier and occasionally antagonistic Cindy is the Veronica. In the end he chooses the Veronica, Cindy.
- McSpanky's, which is in a burger-shaped building, also including the giant head of the mascot sticking out of its side, with his mouth serving as the drive-thru window.
- The lolipop on the Candy Bar. Although according to Nicktoons Unite, these are only huge to the cast, and would be even smaller than normal to real, live action humans.
- Black Best Friend: Libby.
Carl: Not that fresh air and ticks in your sleeping bag isn't fun, but why do we have to go camping with you, Jimmy?
Jimmy: Because if you don't, I'll be forced to publish these high-definition photos of you two playing with Pomono Beach Debbie Dolls.
Sheen: Pomono Beach Debbie is an action figure! She possesses special powers that can defeat any adversary ... except Ultra Lord, of course.
- In the episode where Libby, Sheen, and Jimmy run for class president: Sheen blackmails Carl with an embarrassing photograph of him at a party.
- Bond Villain Stupidity: Professor Finbarr Calamitous in "Operation: Rescue Jet Fusion".
- Brain Critical Mass: Jimmy's normally ditzy friend Sheen gets his intelligence increased with Jimmy's Phlebotinum and gains telekinesis.
- Brain Wash Residue: Depending on your interpretation of the episode "Love Potion 976/J". Considering that we don't know the extent of the after effects of those love potions, you could have a nice debate on whether Jimmy, Sheen, and Carl's respective loves for Cindy, Libby, and Judy is "real".
- Brawn Hilda: After time traveling into an alternate future where he is rich, Jimmy soon discovers he has a cranky, hideous nanny named "Hilgo."
- Brilliant but Lazy: Why do something as simple as neatly put away your piles of pants when you can implant chips in them that do it for you? Carl and Sheen call him out on this, though.
- The Bully: Butch is a typical school bully who doesn't have any friends, but an even bigger one is Terry in "Safety First".
- Bumbling Dad: Hugh.
- Butt Monkey: Jimmy. His inventions usually cause troubles. And when it doesn't come to his inventions, he's picked on by those left and right. How rare is it that the main character falls under this trope?
- For these reasons, Jimmy might also be described as a Woobie.
- What about Carl? He's the Guinea pig to all of Jimmy's experiments.
- Camp Gay: Principal Willoughby can come off as this, with his campy behavior and his love for Judy Garland and musical theater.
- Cannot Spit It Out: Cindy and Jimmy to each other, and, to a lesser extent, Libby to Sheen.
- Can't Get In Trouble For Nuthin'
- Captivity Harmonica: After being thrown into the brig by the Junkman, Sheen does this.
- Catch Phrase: Jimmy - "Gotta Blast" in the movie and "Brain Blast" in the series.
- Cat Fight: Cindy and Green-Skinned Space Babe April the Gorlock in "Win, Lose, or Kaboom".
- Character Development: For a series so episodic in nature there's a surprising amount, though not in terms of learned aesops, but interpersonal relationships. Throughout the series you can note small but noticeable changes in character interaction. Especially when it comes to romantic couples.
- Chekhov's Gun: The solution to the problem in the episode is usually this.
- Chosen One: Sheen is called "The Chosen One" by the monks of Shangri Llama, thanks to his strange ability to put his foot behind his head. Subverted because the monks don't really believe he's the true Chosen One - they were just sick of waiting around for the real one to show up.
- Christmas Episode: "Holly Jolly Jimmy".
- Colony Drop: A meteor starts to head toward Retroville just after Jimmy dumbs himself down.
- Comedic Underwear Exposure:
- Jimmy, Carl, Sheen and Cindy's pants get minds of their own and run away... in the first episode.
- The famous "I see London..." gag is actually said in the first episode/movie, by Cindy, when Jimmy's pants fall down.
Cindy: I see London, I see France!
Carl: Wow, you have really good eyesight....
- Comic Trio: Jimmy, Sheen, and Carl.
- Confusing Multiple Negatives: Sheen to Mrs. Fowl in "Sheen's Brain". Carl tries the exact same trick, but Mrs. Fowl tells him to "PLANT IT!"
- Contrived Coincidence: See Colony Drop above.
- Covered in Gunge: In "The Tomorrow Boys", a bucket full of Mrs. Vortex's repulsive chafing-foot scum gets dumped all over Sheen's head.
- Crossovers: Three times with The Fairly Oddparents in the Jimmy Timmy Power Hours.
- Cut Lex Luthor a Check: Jimmy and his parents could have been millionaires if he sold some of his inventions instead of just making them for fun.
- They backfire way too much for someone to mass produce them, though.
- Also, Jimmy's dad once got a job making toys, which Jimmy amped up with his technology. The first one was met with such success that he got the job... as long as he kept designing toys of that same calibre every day. Jimmy ended up exhausting himself after a few days, which led to the accident of the week; the Nanobots making a rampage on Retroville on a doll-faced toy tank that grew in size to be a real tank.
- Daddy's Little Villain: Beautiful Gorgeous.
- Demonic Dummy: Flippy.
- Demoted to Extra: Nick - he was a somewhat relevant character in the movie, even with just an Informed Ability. In the series, he hardly gets any screen time.
- Disqualification-Induced Victory: During a parent/child competition, Jimmy uses technology to augment his dad's athletic skills and ends up disqualified.... and his Rival-slash-not-girlfriend also gets disqualified because she used an Olympic-athlete aunt as a ringer for her mom... and then every other team admits to doing a disqualification-worthy fault at one point of the competition or another, leaving only Jimmy's Chew Toy friend Carl and his equally-unlucky dad (who were dead last) the winners by default.
- Distracted by the Sexy: Sheen with practically any attractive female (most notably Libby, Beautiful Gorgeous, Sally and Princess Guan Qi "Peggy" Tsu); Jimmy with Betty Quinlan, Sally, April, and later with Cindy. And Carl with Jimmy's mom.
- The Ditz - Bolbi, though he seems like just a goofy foreigner at first.
- Do-Anything Robot: Goddard, Jimmy's Robot Dog, seems to have a large arsenal of gadgets tucked away inside his chassis.
- Door To Door Episode: Complete with Jimmy using science to employ a Zany Scheme.
- Dutch Angle: Spoofed in "The Evil Beneath" where during the villain's brief and crazy Motive Rant the camera slowly tilts itself, which causes his henchman and furniture to slide in the direction the camera is tilting.
- Eat The Camera: Seen at the end of "The Phantom of Retroland" after among seeing the real Phantom, Hugh runs screaming right into the camera, his mouth covering the frame and turning it black.
- Egocentric Team Naming: When Jimmy and his friends gain superpowers due to cosmic radiation he immediately calls them the "N-Men" (as in, Neutron Men), despite a couple of protests.
- In the episode where they form a band, Sheen proposes the name "Sheen and the Sheenettes".
- Eigen Plot: Win, Lose, and Kaboom, to the point where Jimmy's Character Development is based around realizing it is one and learning he can't do everything by himself.
- Election Day Episode: One episode had Cindy and Jimmy face off against each other for class president. They were both disqualified for cheating, so the election is given to Bolby the weird new foreign exchange student.
- Epic Fail: After losing to many times in a gym race against Cindy, Jimmy sprays his shoes with a chemical compound to give him super speed. He runs in circles around her and showing off how fast he is, all gloating and confident, but he still lost. Why? Because he fell for the old point-and-look-behind-your-back distraction, the object of interest being a "1957 Van de Graff electrostatic generator".
- Eskimos Aren't Real: Sheen is positive that ancient Egyptian curses are a myth, just like the Loch Ness Monster and North Dakota.
- Everyone Can See It: Jimmy and Cindy. Thankfully, the Belligerent Sexual Tension gradually faded into a genuine attraction, and they finally got together in the last episode of the series.
- Everything's Better with Dinosaurs: "Sorry, Wrong Era".
- Everything's Better with Monkeys: "My Big Fat Spy Wedding".
- Evil Twin: Jimmy's evil clone in "Send in the Clones".
- Evolving Credits: Certain clips in the opening eventually got replaced with clips from newer episodes. Libby got promoted to opening titles at the same time.
- Expy: When they all get superpowers it is exactly the same as other well-known superheroes. Cindy has Superman flight and strength, Libby is The Invisible Woman, Sheen is The Flash and Carl...well has burps that seem like Black Canary. Jimmy was originally just turned orange, until he got angry...
- Tee is an alien who talks and acts like Mr T.
- And another alien, Travoltron, acts like John Travolta. Or at least his character in Saturday Night Fever.
- The third one, Zix, talks like Jon Lovitz. A bit more devious than Jon Lovitz though ...
- Quentin Smithee seems to be simply an expy of Quentin Tarantino (combined with a nod to the tendency for directors who have disowned films to credit themselves as Alan Smithee) up until we find out he's actually Professor Calamitus
- Jet Fusion is a James Bond expy.
- Face Full of Alien Wing-Wong (Carl is impregnated with an alien child in "Who's Your Mommy?". The extra fat grows out from well, his butt - but let's not go there.)
- Faeries Don't Believe in Humans Either: Pops up at the end of the sleepover episode. The climax of the episode features a series of increasingly-nonsensical Catapult Nightmares involving the various characters and a flying vampiric cannibal pizza. The final nightmare turns out to belong to an actual pizza vampire, sleeping in his pizza box; when he explains his terrible dream to his wife, she consoles him that children don't exist, everyone knows that.
- "Fantastic Voyage" Plot: "Journey to the Center of Carl".
- Fem Bot: In the episode "Maternotron Knows Best", Jimmy constructs a robotic substitute mother while Judy is away at the spa.
- Five-Man Band:
- F Minus Minus: In one episode, Sheen gets an F with four minuses on a test.
- "Freaky Friday" Flip: Jimmy and Cindy in "Trading Faces".
- Incidentally, at the end (where they had to manually switch back their memories) They found that one of the two had an extreme dislike of the other one. However Sheen said that it got too confusing reading the hilariously long name and deleted it, never getting to the end (and thus, figuring out who it belonged to). It is after that one that the two started getting closer.
- Free-Range Children: The fifth grade cast behaves more like young adults/older teenagers. They run all about Retroville, hang out at the local fast food joints, and that's only what they do when not on an adventure caused by Jimmy's invention.
- From the Mouths of Babes: Baby Edward "Eddie" Neutron, Jimmy's infant evil cousin, who can be very crass at times.
- Funny Foreigner: Bolbi Stroganovsky from Backhairistan.
- "Slap slap slap, clap clap clap, slap, slap, slap, clap clap clap..."
- Future Loser: Jimmy in the bad future in "The Tomorrow Boys".
- Garage Band: There was an episode where Jimmy & co. try to start a band for a talent show.
- Getting Crap Past the Radar: Now with its own page.
- Ghost in the Machine: Playfully parodied in "Incredible Shrinking Town", where Sheen pretends to be Tee's inner voice.
Tee: "Thanks, bug in mah head!"
- Giant Spider: "Stranded".
- Girls Have Cooties: Jimmy, Sheen, and Carl all exhibit this sentiment from time to time, especially at the beginning of the series. It wears off as the show progresses, however, giving way to Distracted by the Sexy.
- Give Geeks a Chance: Sheen and Libby, definitely.
- Godzilla Threshold: In the finale, Jimmy asks Carl to take his rocket and bring the N-Men packets with him. You know, the chemicals that would bring back the superpowers that put the entire cast on the brink of death last time? Carl sure does.
- Gold Fever: Ruby madness in "A Beautiful Mine".
- Goofy Print Underwear: In "When Pants Attack", Hugh runs around in a pair of white, heart-covered boxers. He can be seen wearing these (and only these!) again in "Lights! Camera! Danger!" during his Gollum impression.
- In the same episode everyone else Sheen's imported Ultralord underwear, Jimmy's plaid boxers and Cindy's polka dot panties
- On one occasion, Carl's underwear was said to have llamas on them.
- Green-Skinned Space Babe: April the Gorlock.
- "Groundhog Day" Loop: Jimmy's birthday in "Hypno-Birthday to You".
- Justified in that his parents were brainwashed to think every day was his birthday.
- Halloween Episode: "Nightmare in Retroville".
- Hand Puppet: Sheen in "Broadcast Blues".
- Handshake Refusal: In "The Eggpire Strikes Back", Jimmy refused to shake hands with King Goobot, suspicious of a picnic he's hosting.
- Hand Wave: Naturally, due to the show playing fast and loose with science. Most blatantly used when Sheen asks Jimmy how they could survive in space without spacesuits or how they can get to the moon in mere minutes, but Carl's singing blocks out Jimmy's answers.
- Hate Plague: Ruby madness in "A Beautiful Mine".
- Head Desk: Done by Jimmy when he couldn't think of a script for a movie.
- Hilarious Outtakes: These appear out of the blue at the end of the episode "Crouching Jimmy, Hidden Sheen".
- Hollywood Tone-Deaf: Sheen is mocked relentlessly for his inability to sing throughout the series - there is even a reprise song number at the end of "My Big Fat Spy Wedding", where the characters belt out in glorious harmony "We all can sing except Sheen!" Becomes beneficial in "Attack of the Twonkies" - Sheen's singing is so bad that it actually puts the Twonkies (who normally become enraged and then mutate when they hear music) to sleep.
- Horned Hairdo: In one episode, Jimmy clones himself to make multiple Literal Split Personalities. The evil clone has two tufts of hair in contrast to Jimmy's one.
- Horrible Camping Trip: "Aaughh!! Wilderness!!" due to Hugh's stupidity.
- How Do I Shot Web?: "The N-Men".
- Humans Are Morons: Meldar and most of the aliens from "'Win, Lose and Kaboom" laugh at the human contestants because it took them long to transport themselves to the game show.
- Idiosyncratic Wipes: Almost every scene transitions with the show's trademark atom logo flying away and then back towards the camera, with several similar music cues to accompany it.
- Idiot Hero: For a genius, Jimmy sure makes a lot of utterly stupid decisions. In fact, most of the conflict that goes on in this show is the result of Jimmy making a questionable judgment call in the first place regarding his experiments. But then again, Jimmy's lack of common sense is arguably one of the main points of the series. He may be a "genius," but he's still a child.
- I'm a Humanitarian: Implicitly Carl, after thinking his stomach was growling during the Horrible Camping Trip (it turned out to be a bear.)
Carl: Oh no... It's starting! The gnawing hunger! MUST... RESIST... DESIRE... FOR HUMAN FLESH!!''
- I Know Karate: Cindy - she actually says this in "King of Mars".
- Important Haircut: Libby gets one in the episode "Beach Party Mummy" to fool a bunch of mummies that were chasing the gang. She keeps the new look for the remainder of the series.
- Impossibly Delicious Food: In the episode "Krunch Time".
- Incredible Shrinking Man: Jimmy at various points throughout the series. Lampshaded in "Incredible Shrinking Town".
- Ingesting Knowledge: Jimmy creates Books Chewgum with this effect.
- Isolation Despondency: In "The Feud", Jimmy and Carl are forbidden to play with each other again by their fathers, due to an incident involving weed spray that was borrowed and never returned.
- Jimmy's Mom: "Has Got it Going On", says Carl.
- Journey to the Center of the Mind: Jimmy goes to Carl's mind in "I Dream of Jimmy".
- Just Testing You: "Carl Wheezer, Boy Genius" has this exchange:
Jimmy: May I suggest that instead of the arm-missiles button, you push the one right below it?
Carl: I know what button to push! I was just testing you.
- Kids Are Cruel
- Large Ham: Both King Goobot and Ooblar have their moments. "HELLO, TOAST!"
- Last Minute Hookup: Jimmy and Cindy in "Lady Sings the News".
- Latex Space Suit: Cindy in "King of Mars".
- Legion of Doom: "The League of Villains".
- Limited Wardrobe: The only time a character's plain-clothes outfit changes is the episode where Libby gets a makeover, and declares that she's keeping the new look. From then on, that became the outfit she wore every episode.
- Love Triangle: Betty and Cindy toward Jimmy, though the latter two would claim not to like each other.
- In the Jimmy Timmy Power Hours, there was also Timmy/Cindy/Jimmy — the two boys fight over her in the second power hour ("When Nerds Collide"), but Cindy ends up in a way, going with both of them since she wished for a cross-dimensional dance party for Dimmsdale and Retroville's elementary schools so she can dance with both Jimmy and Timmy.
- Carl's infatuation with Jimmy's mother.
- Love Potion: Another one of Jimmy's inventions. It causes him to fall for Cindy, and Sheen for Libby. And Carl falls for Jimmy's Mom, which then goes on to become a Running Gag. Poor Carl.
- Poor Carl? How about "Poor Judy?"
- Mad Scientist's Beautiful Daughter: Beautiful Gorgeous, Calamitous' daughter, subverts this: she's actually evil.
- The Masochism Tango: Jimmy and Cindy
- Mel Brooks: Guest stars in the Christmas Episode...as Santa Claus.
- Me's a Crowd: Jimmy's clones in "Send in the Clones"; each one represents a different personality type.
- Meaningful Name: James "Jimmy" Isaac Neutron is not surprisingly, interested in science.
- Also Jimmy's classmate Nick Dean, a child version of move badboy James Dean.
- Sheen Estevez; a Shout-Out to Charlie Sheen and Martin/Emilio Estevez.
- And Jet Fusion, the in-show version of James Bond (fusion actually means bond)
- Beautiful Gorgeous is beautiful and gorgeous.
- Movie director Quentin Smithee, who had no records at all... because he was really Professor Calamitous in disguise.
- Mind Screw: Jimmy traversing Carl's Dream. Being well, a dream, for the most part, it has no logic or sense. Though like most dreams, Carl sees it as perfectly normal. So Jimmy, in order to prove to him, without a doubt, that this is not the real world, does something that could possibly never happen in real life, he kisses Cindy.
- Missing Mom: Sheen. Word of God says his mother died when he was young - they don't say her cause of death, however.
- Mr. Seahorse: See Face Full of Alien Wing-Wong above.
- Monster Mash: Occurs in the Halloween Episode, "Nightmare in Retroville".
- My Brain Is Big: Averted to an extent, with the size of Jimmy's head. A lot of characters assume that Jimmy's big head explains his extreme intelligence, but in reality he just has a gigantic hairdo.
- Played straight however, in the episode "Sheen's Brain", where Sheen's intelligence increases as his head grows bigger.
- My Future Self and Me: Jimmy, Carl, and Sheen all get to meet their future selves as well as future Cindy and Libby.
- Naked People Are Funny: In "Jimmy Goes to College", the boy genius streaks through the halls of the Pomona School of Advanced Physics - only to find himself face to face with the elderly female patroness of the coveted Moran Grant. He quickly covers his front with a book and his backside with an exit sign.
- In the movie, Sheen can be seen naked - peeing, in the shower.
Sheen: I'm peeing! In the shower! I'm still doing it! ( Pumps both hands in the air) Go go go!
- Never My Fault: In "King of Mars", Cindy blames Jimmy for her brief Face-Heel Turn with Eustace, for never paying any attention to her, and after Eustace double-cross her.
- Never Say "Die": In "The N-Men", Jimmy has to save himself and his friends before their "life forces" are depleted.
- Nice Job Breaking It, Hero: Nearly every episode and movie is this. Jimmy's inventions and motives usually cause the problem of the week and it's up to him to fix the problem he caused.
- Of course, Jimmy's friends also get in on the act every now and then. In "The Eggpire Strikes Back" Cindy told King Goobot how to get into Jimmy's lab, giving him the tools he needed to revive Poultra.
- Offscreen Teleportation: Seems to be an ability of the Needleheads from "Win, Lose and Kaboom".
- One-Wheeled Wonder: Jimmy Neutron designed his android little brother Brobot this way.
- Only Known by Their Nickname: Almost every major character.
- Overly-Long Scream: Lampshaded by Carl in "The Tomorrow Boys" when Jimmy finds out in the Bad Future that he is MARRIED to Cindy. He starts screaming, we cut to commercials... We come back, and he's still screaming.
"Wow, Jimmy, you just screamed for 4 minutes
- Other Me Annoys Me
- Panty Shot: Cindy gets a few...
gracious egregious shots (blue thong) in "The N-Men".
- Parody Names: Quite a few of the episode titles.
- Examples include "I Dream of Jimmy" (I Dream of Jeannie), "A Beautiful Mine" (A Beautiful Mind), "The Junkman Cometh" (The Iceman Cometh), "Love Potion #976/J" (Love Potion #9), "Crouching Jimmy, Hidden Sheen" (Crouching Tiger, Hidden Dragon), "My Big Fat Spy Wedding" (My Big Fat Greek Wedding), and "Trading Faces" (Trading Spaces, although the episode was originally titled "A Mind is a Terrible Thing, Two Ways" - a parody of the educational slogan "a mind is a terrible thing to waste).
- "Journey to the Center of Carl" (Journey to the Center of the Earth) is actually a "Fantastic Voyage" Plot.
- Parody Episode: Quite a few. "Lights! Camera! Danger!" is notable for combining parodies of The Matrix, Harry Potter, The Lord of the Rings, and Chicago, and references a truckload more.
- Playing Sick: Invoked by Jimmy when he invents patches that make the wearer sick when applied. He gives them to the rest of the kids so they can skip school. Until they get absorbed into their bodies, forcing Jimmy and Sheen to pull a "Fantastic Voyage" Plot into Carl to get the cure needed.
- Phlebotinum Induced Stupidity: Jimmy's Brain Drain in "Normal Boy" makes him an idiot.
- Pivotal Wake-up
- Plot-Induced Illness: Invoked when Jimmy invents a "sick patch" that make the wearer sick when applied, which the kids then use to stay home from school.
- Precocious Crush: Carl toward Jimmy's mom, Judy.
- Premiseville: Retroville has a retro theme.
- Ptero Soarer: "Sorry, Wrong Era" has a classic example in the form of a Pteranodon that, for a short list, is called a "pterodactyl", is scaly, has pointed leathery wings, can pick things up with its feet, rears its unusually large young like a bird, flies inland, eats lizards instead of fish, lives in the same time as T-Rex and is bipedal. That being said, the writers did manage to get the lack of teeth and single wing finger right (although said wing finger is unusually flexible).
- Punny Name: Ms. Fowl has a few bird-like attributes
- Real Award, Fictional Character: When Jimmy peeks into his and his friends' futures in one episode, he sees himself as the first-ever winner of the Nobel Prize in bulk.
- Reality Warper: Meldar, the Big Bad of "Win, Lose and Kaboom" can do this thanks to his matrix generators. He even says that he can warp reality.
- Recycled In Space: In-Universe. The school play from Out Darn Spotlight was known as Macbeth in Space.
- Recycled: The Series: This show was the result of the successful Jimmy Neutron movie.
- Recurring Extra: The Twonkies.
- Retro Universe: Retroville.
- Rival Turned Evil: An unusual case in "The N-Men" - Jimmy himself is this due to finally getting fed up over how Cindy keeps overshadowing him. This sets him on a Hulking Out rampaging spree, and the irony is that the only one who stops him is Cindy herself.
- Robot Dog: Goddard.
- Robot Kid: Brobot.
- Romantic False Lead: Betty.
- Running Gag: Jimmy making something using Hugh's toasters.
- Carl's crush on Jimmy's mom, Judy.
- Nick: "Oww, I broke my leg."
- The exact same footage is used for this scene every time this happens. "Lady Sings the News" even Lampshades it when Jimmy and Cindy note that this has happened 15 times with Nick, and that everyone is expecting it to happen to Nick again shortly after he recovers.
- The Twonkies that Sheen had after an episode appear in several later episodes; they don't morph however.
- Various iterations of "the little boy's room" are used when a character has to pee, including "the little boy's ocean" by Carl when the boy's are flying over the ocean in Jimmy's hovercraft.
- Carl also had his highly sensitive scapula.
- Samus is a Girl: Beautiful Gorgeous. She was wearing robotic armor similar to Samus'.
- Sarcasm-Blind: Cindy in "Out, Darn Spotlight".
- Sassy Black Woman: Libby.
- Satire/Parody/Pastiche: Numerous examples of this include "Attack of the Twonkies" (Gremlins), Monster Hunt (Jaws), "Stranded" (Cast Away), "Love Potion #976/J" (Love Potion #9), "Lights! Camera! Danger!" (The Matrix, The Lord of the Rings and Harry Potter, to name a few), "Win Lose and Kaboom" (every gameshow ever) and "Operation: Rescue Jet Fusion" (James Bond).

- Self-Destruct Mechanism: Goddard has one, though he can reassemble himself.
- Severely Specialized Store: Retroville has stores like Cheese World, Mime World, and Rug World.
- Shout Outs (Some episode titles, such as "The Tomorrow Boys")
- Meltyface, anyone?
- "Uh, Libby, I don't think they need no stinkin' badges."
- Jimmy's Blue Time Traveling Telephone Booth, anyone?
- Cindy's entire character could be a shout out to June from KaBlam!! Let's see, bossy 10-11 year old girl with a ponytail, crush on the main boy...
- "The N Men", particularly Retroville's reaction, is similar to the X-Men.
