Cindy doesn't hold her fists when she wants to teach Jimmy or any other boy in the show a lesson. In fact, she can be so rough with them it would probably not be allowed in more recent cartoons, due to the audiences' growing awareness of the issue of female-on-male violence in schools compared to that of the 2000s.
Other times, though, averted. Sheen's Hispanic origins, for example, won't save him.
Adaptation Displacement: While The Movie was very popular, and still pops up on Nick every now and again, people often forget about it or think that it came after the show.
Banned in China: The Arabic version of the show removess pretty much anything that hints at there being anything more than just plain friendship between child characters. It's done in such a crude manner that entire scenes are reduced to just a few lines of dialogues with an awkward transition to the next and some of the more Ship Tease prone episodes end up downright incomprehensible.
Called the Cretaceous period the Cretaceous era (the terms aren't interchangeable [even though people do use those words interchangeable], and it was the wrong period to begin with).
Said that Thomas Edison invented electricity (electricity existed beforehand; Edison was one of many to do experiments with it).
Said that as a hamster, he is high in HDL (high-density lipoprotein) cholesterol, which is bad (shouldn't that be low-density lipoprotein [LDL] cholesterol?).
Saying that creating vaccine for a viral infection by extracting its mitochondrion. Virus has no mitochondrion since it's an organelle found in most eucaryotic cells. No "Jimmy said it was a germ" excuse since they clearly used an image of typical bacteriophage and it's not even a virus known to cause disease in human.
Designated Hero: Jimmy isn't an abrasive character, but he does cause many of the problems he has to fix. Cindy herself lampshades it.
Designated Villain: Cindy has a tendency to be subject to this trope more often than other characters:
It's especially apparent in "Holly Jolly Christmas". She and Libby are given lumps of coal from Santa at the end and Libby suggests that this is because of their attempting to humiliate Jimmy, smoothly glossing over the fact that the reason Cindy and Libby decided to do it in the first place was to make Jimmy pay for hurting Carl's feeling in class, when Jimmy tried to persuade Carl that Santa Claus doesn't really exist. In that particular scene Cindy is angry at Jimmy not because she necessarily believes in Santa herself but "that's not the point". Later on, she holds Jimmy responsible for ruining Christmas first for Carl, then for everybody else (and she's 100% right about that since it's Jimmy who accidentally knocked out Santa). All in all, Cindy and Libby definitely could have been nicer to Jimmy but seeing them punished and Jimmy rewarded with a precious gift seems unfair to say the least.
In "Best in Show" Cindy has Goddard disqualified from a pet contest on a very solid basis of him not being a real dog and thus not eligible for participation according to the rules which is enough to brand her the asshole of the week. And while that doesn't excuse her not being able to spit out a thank you to either Jimmy or Goddard when the latter saves her life at the end, if Jimmy didn't use the opportunity to rub it in her face how wrong and immoral she was and how much better a person he is, she most likely would have apologized.
"Funny Aneurysm" Moment: In Retroville 9 Jimmy creates high-tech baseball gloves and automatic homerun hitting bats neutronized with the skills of three baseball players for his struggling baseball team. They effectively cheat their way to the little-league finals in Japan. The players Jimmy used were Barry Bonds (an alleged cheater), Mark McGwire (a confessed cheater) and Babe Ruth (dead).
Growing the Beard: More of like Braiding the Hair; episodes after "Beach Party Mummy" tend to stand out more, shedding the spin-off-of-the-movie feel. In that particular episode Libby has decided to keep her hair braided, making her stand out more as well.
Life Imitates Art: "Retroville 9", aired 2003, shows Jimmy & Co. going to Nagoia, Japan to participate in the "Junior Baseball World Championships". No such tournament existed back then but a 12U Baseball World Cup was founded in 2011, with a 15U equivalent coming up the following year. Seeing as that was a Season 2 episode, Jimmy and others would have qualified for the former. Japan being the tournament's host also makes sense as baseball is a very popular sport there.
Moral Event Horizon: Evil Jimmy starts off as a simple prankster at first...up until he creates an evil version of Jimmy's planet and attempts to destroy the old one.
More Popular Spin Off: It's not that the film that kickstarted the show is not remembered at all (although its Academy Award nomination certainly is) but it certainly seems that more people view it as the series' Big Damn Movie rather than a motion picture in its own right.
Carl Weezer. Primarily because he came off really, really annoying with his Squicky interests in Judy Neutron and his constant complaints about his scapula. It didn't help his character Took a Level in Jerkass later on.
Sam. While he was already a Jerkass when the show started, The N Men showed his asshole status when he sends the kids (minus Jimmy) to Area 52 due to their carelessness. While Jerkass Has a Point stands here, his behavior isn't necessary. It comes even more to an annoyance when Sheen came to him for help in order to get a main component to make Carl burp against Hulk-Jimmy (It Makes Sense in Context), but Sam rudely says no, all while calling Sheen a 'freak', prompting Sheen to just take it and have Sam complain that he owes him a $1.80 for it. And even after thanking him at the end of Jimmy's speech, he's still complaining about the $1.80.
Miss Fowl to some due to her treatment to Sheen (at least beforePlanet Sheen)...
Shipping: Yes, even in a show where most main characters are age 10 to 13.
The title card for "Hypno-Birthday to You" has a copyright-friendly variation of The Beatles' "Birthday" playing over it.
The music we hear in the background during the Mt. Incredibly Unstable scene in "The Mighty Wheezers" bears an uncanny resemblance to the theme of the 1989 ''Batman'' movie.
Tear Jerker: The scene in "Brobot" where Jimmy tries to deactivate Brobot. When he explains to Brobot what he's doing, Brobot (who, for once, doesn't sound happy or excited at all) says, "But...but then we can't play anymore. And you're my...big brother." Jimmy starts feeling guilty, and sheds a single tear...which lands in Brobot's circuitry and seems to short him out, causing Jimmy to feel even more guilty. It turns out that Brobot's indestructible, and all the tear did was tickle him, but still.
During "Return of the Nanobots," Hugh ends up believing he's the last person on Earth due to everyone else being deleted by the nanobots. When he realizes that he's alone, Hugh laments the loss of Jimmy and his wife (whom he actually calls by her first name, Judy).
Somewhat ironically, quite a big part of the fandom will accuse Phineas and Ferb of doing the very same thing in regard to The Adventures of Jimmy Neutron itself.
They Wasted a Perfectly Good Plot: For Jimmy/Timmy Power Hour 3, which was originally was supposed to be a Grand Finale for bothshows. Who didn't want to see a 3D Dimmsdale and a 2D Retroville, Crocker spazzing out in 3D or the alien Mark Chang in 3D? And better yet, send the Gigglepies to Retroville and the Twonkies to Dimmsdale (we wonder if Timmy has learned from the Gigglepie experience?).
Uncanny Valley: While the CGI is by all means decent for the standards of early 2000s computer animated TV shows, a lot of the character designs may get surprisingly creepy looking at times.
Unfortunate Implications: "The Egg-Pire Strikes Back" plot: A majority-white city is flooded with a bunch of aliens with a different skin color. The locals are sceptical about the newcomers seeing how they had some nasty problems with them in the past but a couple of gifts and some "We're good now" talk is enough to turn the Retrovillians against the vocal minority who claims the aliens should not be trusted. The aliens then proceed to take over Retroville's education as well as police and military forces, effectively stepping in charge of the entire town. Only then it turns out that the vocal minority was right after all and the aliens' intentions are not clean at all. Shall we go on?
Brobot might not exactly be fandom's favorite but he clearly doesn't come off half as annoying as other characters, who literally can't stand him, make him out to be.
In "Brobot" he is initially liked by other kids, that is excluding Jimmy himself who feels he is getting sidelined. Even then, Brobot's childish demeanor and naïve admiration for his "big brother" Jimmy make him difficult to dislike.
Even more apparent in "The Junkman Cometh", in which Brobot tricks Jimmy and his friends into coming to the Moon in order to play it. While the six hundred and forty-seven messages from him that Jimmy has ignored are supposed to emphasize Brobot's annoying behavior in regard to his "brother", it begs the question, why is Jimmy being such a douche towards Brobot? It gets even worse later on, when the kids are abducted by the Junkman and prompty set free by Brobot he asks them to help him free his robot parents, to which Sheen and Carl suggest that they should leave as fast as possible instead and even Jimmy takes his sweet time before agreeing to help Brobot, making you wonder who really is supposed to be The Scrappy in all this.
To some extent, Cindy. Within the show she gets called annoying at least on a few occasions and yet you'd be hard pressed to find anyone among the fans who wouldn't like it when she is on screen. What makes her likeable, aside from the obvious Ship Tease factor, is her sassy personality as well as genuinely hilarious ways she makes fun of Jimmy.
Vindicated by History: When it first aired, many slammed the show for being too similar toDexter's Laboratory, and the humor being So Okay, It's Average. However, since being off the air for several years now and a certain infamous fan animation reminding people of the series, people have since rediscovered it and given it a second chance, and got to see how the later seasons grew the beard in comparison to how it started. Nowadays, it's often hailed as one of the, if not the, last great Nicktoons on Nickelodeon.
