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 think that it came during the early run of 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.
Cindy to some extent. While people are fully supportive of her and Jimmy ending up together, some people think Cindy's pride is no excuse for how she treats Jimmy and his friends. This is when people really miss how more sympathetic and friendly she was in the movie.
Complete Monster: Evil Jimmy and all of the clones on Evil Earth. They sadistically torture people and murder innocents for fun and they try to kill Jimmy when he does something even slightly good. Not to mention Evil Jimmy was planning to have Jimmy become the Last of His Kind by causing mass genocide. When Jimmy saves the world, he plots to keep Jimmy in his cruel, dark and twisted world by sucking him into a void of darkness. Not to mention in his first appearance, he made Jimmy ice his clones, who mistook the real Jimmy for the evil one and you see how reluctant Jimmy is to do that.
Meldar. He may seem like an ordinary game show host, but he's really a genocidal maniac who torments other life forms for pleasure.
Stated that Australia isn't a continent (it is). Of course, he could've just been bluffing and trying to make up an excuse to argue with Cindy.
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.
In "Beach Party Mummy" Jimmy translates Egyptian hieroghlypics using a "Sanskrit to English translator with a Rosetta Stone upgrade" built in his watch. While the Rosetta Stone piece makes sense (it was a rock stele covered in an inscription written in three different scripts, including Egyptian hieroglyphics, thus enabling the archeological world to finally decipher a good chunk of them), Sanskrit is an Indo-European language with zero relation to Ancient Egyptian (this one in turn is classified as Afroasiatic, much like Hebrew and Arabic).
Designated Hero: Jimmy is not a bad person, 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.
First Installment Wins: While the other two seasons are when the show started getting more popular, some people think season one had better humor and character portrayals.
Fountain of Memes: Hugh Neutron and even moreso Bolbi have an internet following based on this.
Sheen and Carl are also this, to a lesser extent.
"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.
Sheen pretending to be Tee's conscience in "The Incredible Shrinking Town" is funny in light of "League of Villains" (where Sheen is responsible for Tee's Heel–Face Turn).
Jerkass Woobie: Cindy. When you think of it, the only reason she acts like a bitch in the first place is due to years of her mother pushing so hard all the time to be perfect and her father barely being around. Not to mention that she feels inferior to Jimmy (and to an extent, Betty), so she hides her feelings by pretending to dislike him. There's also the fact that besides Libby and Brittany, she literally has no friends.
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.
"Hi, i'm Paul!"note A line taken from the DNA Productions Vanity Plate that appeared at the end of the show.
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 and forces Jimmy to watch, not to mention trap him in his world of darkness.
Meldar may seem like an ordinary game show host, but he threatens to blow up the losing planets and forces the losers to watch.
Eustace makes many Kick the Dog moves to Jimmy and is already an unlikeable jerk, but using Cindy to emotionally crush Jimmy and forcing Jimmy to watch Goddard die? That is way over the line.
King Goobot crossed it when he and the other Yolkians pretended to have reformed and had them all turn against Jimmy, all part of his plan to emotionally crush Jimmy.
Beautiful Gorgeous hypnotizes Jet into killing Jimmy in front of many innocent lives and have him arrested for murder.
More Popular Spin Off: It's not that the film that started it all 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. Primarily because he came off really, really annoying with his Squicky interests in Judy Neutron, his whining 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 Jimmy and Sheen.
At the end of "Carl Wheezer: Boy Genius", where Jimmy punches Carl in the face after being verbally abused by him.
In the final episode where the gang leaves him in a stockhold and his scapula hurts.
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).
In "Sheen's Brain", Jimmy and Carl realize that Sheen's brain growing will cause his head to explode. They disguise themselves as Ultra Lord to try to convince him to revert to his original intelligence, but he brutally strikes them with a lighting bolt and kills them. When he sees Carl and Jimmy and believes them to be dead, he realizes he's killed his two best friends. Realizing what a monster he's become, he voluntarily decides to go back to his normal self.
When Cindy tearfully admits she loves Jimmy just before she fades to a near-death point in The N-Men, or tries to as all she says is "luh...luh...luh..." and then collapses with Jimmy picking her up and asking, "Cindy what? Like? Loathe? Love?" and then setting her down on the ground as he begins to calm down. When Jimmy changes back, he tries to ask her what she was saying, but he sees that she's dying.
In "Stranded", Cindy begs Jimmy to stay on the island with her so they can be together forever, but sadly they can't.
In "Billion Dollar Boy", when Eustace sadistically mocks Jimmy into betting Goddard in a robot battle. Then, when Eustace's robot starts beating Goddard senseless, Jimmy's friends realize that Eustace was just using them to emotionally crush Jimmy. To add salt to the wound, Eustace does a major Kick the Dog moment and throws Cindy down on the ground and reveals his true colors to her. Then, when Goddard is knocked out, Jimmy is heartbroken, thinking that Eustace's robot has killed Goddard and looks like he's about to cry at any moment.
In "Make Room for Daddy-O", Jimmy looks at all the photos of the fun times he and Hugh had together and misses having him around.
Somewhat ironically, quite a big part of the fandom will accuse Phineas and Ferb of doing the very same thing in regard to Jimmy Neutron itself.
They Wasted a Perfectly Good Character: Nick. He had a pretty major role in the movie and he's like a big brother to Jimmy. Not to mention he is a perfect foil to Sheen, so you can see a lot of potential in his character. There were even plans to make him part of the main cast in season four.
Brittany as well. She could've made a perfect comic foil to Cindy and Libby, like Carl and Sheen are towards Jimmy.
In fact, name any other kid in Jimmy's class who isn't Cindy, Libby, Carl or Sheen.
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 ugly looking at times.
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 and he's pretty hilarious as well.
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 a small 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.
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 realize how the show had its own identity. Nowadays, it's often hailed as one of the best Nicktoons ever.
The Woobie: Jimmy. For one thing, he's hated because he's super smart, always tries to help people but causes trouble anyways and his parents are the only relatives who care about him and hardly anybody likes him or his inventions. People also laugh at him for being short and don't care if it hurts his feelings. There's also the fact that people show no empathy towards him when he's made fun of. He's also hinted to be lonely a few times. In most episodes you just want to reach out and give him a comforting hug and kiss.
Nick in later episodes. He seems to have no purpose except for randomly breaking his leg to the points where it's just not funny anymore and when you think about it, it's actually really depressing. There's also the fact that he had a lot of potential in his character as stated above. Not to mention that he was in a lot of merchandise, but nobody dared to make him relevant to the series, so he might as well be THE woobie of the entire franchise.
