5[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/jimmy_neutron_6.png]]
6[[caption-width-right:200:He may be small, but he has a ''big'' brain!]]
7->'''Voiced by:''' Creator/DebiDerryberry
8
9-->'''Full Name:''' James Isaac Neutron
10
11The main protagonist. He is a boy with a stunning IQ of 210 and a love for science. From Hypercubes to Hypnorays, Jimmy can whip up the most amazing inventions. However, things have a way of going awry, and more often than not, Jimmy has to save the day from himself. But with friends, family, and a secret lab, there's no problem this boy genius can't handle. Right?
12----
13* AesopAmnesia: At least half of the episode plots wouldn't happen if Jimmy would remember how often his inventions backfired or that using his genius for his own ends has its consequences.
14-->'''Cindy:''' Jimmy, haven't you learned from [[WesternAnimation/JimmyNeutronBoyGenius the Yolkian incident]] not to talk to intergalactic strangers?
15* AffectionateNickname: Hugh calls him "Jimbo".
16* AllOfTheOtherReindeer: Jimmy's brains and brilliance (along with him endangering the town) make him unpopular with the other kids and as a result, he's made fun of and bullied by them.
17* AnimeHair: Lampshaded consistently. It's been compared to a gum massager, soft-serve ice cream, fudge dip, and still other more ridiculous things. He's also been called "Fudgehead" by [[WesternAnimation/TheFairlyOddparents Timmy and Cosmo]].
18* AntiHero: Jimmy is a complex character, often prone to arrogance and mischief, although the good side of his personality usually outweighs the bad one.
19* ArbitrarySkepticism: Best shown in the ''Jimmy-Timmy Power Hour'' trilogy and ''VideoGame/NicktoonsUnite''. Despite living in a world where space aliens and alternate dimensions exist, Jimmy refuses to believe in magic and is convinced that the fairies and associated creatures in the ''WesternAnimation/FairlyOddParents'' universe are merely [[MagicFromTechnology highly advanced computer programs]].
20* ArchEnemy: He has made himself ''[[RoguesGallery a lot of enemies]]'' but probably the three biggest examples are King Goobot, Finbarr Calamitous and Eustace Strych.
21* BadassAdorable: A dorky young ChildProdigy who's saved the world on numerous occasions.
22* BigNo: Whenever Jimmy comes to any shocking realization, you can bet the whole of Retroville will know about it instantaneously.
23** In "The Tomorrow Boys", after learning he gets married to Cindy. In a bit of LeaningOnTheFourthWall, the scream cuts to a commercial. When the show comes back on, Sheen and Carl comment that he had been screaming for four minutes straight.
24** Another Cindy-related moment is when he finally succeeded in asking Cindy on a date, only then he realized what he'd done
25** It even happens with a similar situation where in ''VideoGame/JimmyNeutronVsJimmyNegatron'', where Cindy falls in love with Negatron.
26* BigThinShortTrio: The Short to Carl's Big and Sheen's Thin, although he compensates for his short stature with a combination of both his big skull and his tall, swirly hairdo.
27* BlackSheep: In "Clash of the Cousins," most of the Neutron extended family views him as such, correctly pointing out that, while Jimmy may have saved the day quite often, more often than not, it was one of his inventions that [[NiceJobBreakingItHero caused the problem in the first place]]. Subverted by the end when he saves them all and they appreciate him more, especially since he saves them from the new Neutron BlackSheep, Jimmy's cousin Eddie, who is just as intelligent, but villainous (and a ''baby'').
28* BrainyBrunette: Brown hair? Check. Incredibly intelligent? Check.
29* BrilliantButLazy: 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.
30* BreakTheCutie: He becomes a victim of this whenever something really bad happens to someone he deeply cares about. Especially Goddard. This also happens when his insecurities are shown. In "The N-Men", Jimmy spends pretty much the entire episode being bullied, ignored, and insulted by his so-called "friends". He becomes so fed up, that he turns into a Hulk-like creature and terrorizes the town for revenge.
31* BreakoutCharacter: During the time of the film's release and the early run of the series, Jimmy became Creator/{{Nickelodeon}}'s official mascot.
32* BunglingInventor: While he's undoubtedly a genius, the plots of most episodes are kicked off when his inventions go haywire.
33* ButtMonkey: His inventions usually cause trouble. And when it doesn't come to his inventions, he's picked on by those left and right.
34* CassandraTruth: In the episode "The Eggpire Strikes Back", no one believes Jimmy when he says that the Yolkians, the villains from the film, are still just as evil as ever, until the Yolkians trap them in the park and sic Poultra on them.
35* CatchPhrase: Originally "Gotta blast!", "Think, think, THINK!", and "Brain blast!". The show eased off on these as it went on, eventually getting rid of them entirely. (One exception is "And now, my latest invention, the (insert plot-related-device here!)", which stayed for most of the series' run.)
36* ChickMagnet: He gets a lot of attention from girls.
37* ChildProdigy: A boy genius who has an IQ of '''210'''.
38* CharacterizationMarchesOn: Jimmy is eventually transformed from a shy InnocentProdigy with an everlasting passion for having fun to a more ill-mannered and insufferable boy genius with an everlasting greed for superiority.
39* CheatersNeverProsper: Jimmy sometimes uses his inventions to cheat in competitions, and it ultimately backfires on him.
40** In "Maximum Hugh", he and Hugh are disqualified from the Picnic Games for cheating, though he was the one who decided to admit it and turned down the trophy. In a hilarious example, it turns out that ''almost everyone'' cheated in the games in the first place (Cindy's case was apparently unintentional on her part)... except for the Wheezers, who won by default.
41** Jimmy finds this out the hard way in "The Retroville 9" when he and his friends lose the baseball championships without scoring a single point. Then, Tremendous Jackson offers this hilarious line:
42-->'''Tremendous Jackson:''' Somewhere in the Rytridian Galaxy, Ultra Lord weeps.
43** In "Jimmy for President" has an... unusual example. He is disqualified due to "operating a zeppelin onto school premises" (compared to Cindy and Sheen, who relied on more traditional means, as well as bribery and blackmail).
44* CrazyPrepared: His watch, whose powers depend mainly on the plot. Can include lasers, freeze rays, magno-rays, GPS, tracking devices... you name it, there's probably a gadget for it tucked away in there.
45* CripplingOverspecialization: He's extremely intelligent but sees anything else as fairly beneath him, leaving him useless in a ton of non-science-related activities, including things so simple as ''selling candy door-to-door'' because instead of trying to sell the candy, he's giving chemistry lessons, and is then confused on why it's not working.
46* DeadpanSnarker: In Season 3's "Carl Wheezer Boy Genius".
47-->'''Jimmy:''' *science babble about a spider*\
48'''Sheen:''' Fascinating! Can you make it do the hokey pokey?\
49'''Jimmy:''' Sheen, go home.
50* DitzyGenius: He's undeniably smart, but has a lack of common sense and can be arrogant.
51* DontYouDarePityMe: Subverted. Describing himself as a "genius", Jimmy often brushes off other characters every time they try to point out a problem in his plans and/or his own flaws, thinking they're just trying to feel sorry for him.
52* DrunkWithPower: In "Hall Monster". He becomes hall monitor and, when the principal gives him advice and is told that Albert Einstein was a hall monitor as well, becomes determined to be one of the best. Unfortunately, when combined with his weirdly heavy-handed law enforcement inventions, it leads to a power trip that causes him to run the school like a prison.
53* EarlyInstallmentCharacterDesignDifference:
54** In the original ''Recap/RunawayRocketboy'' short, Jimmy wore a red and white striped shirt. In the movie, this was swapped out for a red shirt with an atom on it.
55** In the show, Jimmy swapped out the shorts and brown loafers he wore in the movie for jeans and sneakers.
56* EndearinglyDorky: This was especially evident in the shorts, movie, and Season 1 where he was a lot more shy, clumsy, awkward, and naive. This is why he gets a lot of attention from girls in-universe.
57* EstablishingCharacterMoment: Jimmy has several early in the movie.
58** He refers to the fighter jets as "nice antiques" when they catch up to his homemade rocket in the first scene.
59** He shares one with Cindy by responding to her show-and-tell about Girl Dinosaurs being superior to Boy Dinosaurs by referring to a sub-field of the scientific community, which she responds to in kind by describing the findings Jimmy used against her as inconclusive.
60** Balancing out his impulsiveness and arrogance, Jimmy is also established to have a large streak of kindness where Carl is concerned, genuinely complimenting the latter on his childish drawing of a frog and making no fuss over his photorealistic drafting of Goddard's second fly-cycle prototype.
61* EurekaMoment: Usually when he has to really think of the solution, followed by "Brain Blast!"
62* FatalFlaw: Jimmy's greatest flaws are a combo of {{pride}} and his lack of common sense; in fact, many of the conflicts in the show are born out of this.
63* TheFriendNobodyLikes: Most of Jimmy's classmates don't like him that much due to his massive smarts which leaves him ostracized. This is especially evident in episodes like "Lights Camera Danger", "Men at Work", "Jimmy Goes to College", and "Normal Boy".
64* FutureLoser: In the 'BadFuture' of "The Tomorrow Boys", Jimmy is a slack-jawed loser, wanted by the evil dictator Libby, with a five-o'clock shadow and Cindy as a wife. Naturally, Jimmy is [[FutureMeScaresMe less than impressed]].
65* GadgeteerGenius: He's only a kid, but he has already surpassed any known scientist in capability. Each episode focuses on one of his inventions although his inventions usually fall prey to FlowersForAlgernonSyndrome.
66* GetBackToTheFuture: Jimmy's dad screwed up with one of his inventions, leaving him, Carl and Sheen in the past.
67* GiveGeeksAChance: Despite being relatively unpopular, he has caught the eyes of girls due to his smarts and heroic nature.
68* HeCleansUpNicely:
69** When Jimmy shows up in a tux for Jet Fusion's wedding to Beautiful Gorgeous in "My Big Fat Spy Wedding", Cindy promptly gets little hearts in her eyes.
70-->'''Cindy:''' So Neutron's the best man? Yeah, more like the best NERD! I bet he'll look like a total... ''(Jimmy shows up outside the church in a tux. Cue fade to pink background, [[WingdingEyes eye-hearts]] and hair patting)'' ...HUNKMUFFIN.
71** During ''Love Potion #976-J'', when Jimmy cleans up for his date with Cindy. Said almost word-for-word by Cindy.
72* HeightAngst: He's shorter that the main casts (and Retroville kids his age in general), and he loses his temper when someone mentions or ridicule his short stature.
73* HellYesMoment: Often. Especially when he's given up all hope...and then his friends forgive him for being arrogant/apologize for being stupid/come back to save him.
74* HiddenDepths: Some episodes imply or outright state that Jimmy may actually be more insecure of himself and is not as conceited or confident as he makes himself out to be.
75* HulkMashUp: In "The N-Men", the kids all get various superpowers that parody real comic book heroes. Jimmy turns orange like [[ComicBook/TheFantasticFour The Thing ]] and becomes a parody of both the Hulk and his alter ego Bruce Banner; while normally mild-mannered and highly intelligent like Bruce, his true powers awaken when he gets mocked and becomes a towering, infuriated beast of a man trying to destroy everything in this path.
76* HulkOut: His actual superpower in "The N-Men". He becomes the [[ComicBook/TheIncredibleHulk Hulk]] with elements of The Thing of the ComicBook/FantasticFour, granting him inhuman strength, agility, and a HealingFactor.
77* IgnoredExpert: Whenever Jimmy tries to use his incredible scientific mind to solve a problem that wasn't directly his fault or he could fix easily if left to his own devices (the Yokians returning, the Mysterious Space-Rock, the Niblonians, etc.), expect human-error, irrational behavior or learned distrust from everyone else to get in Jimmy's way until the problem gets so out of hand that they can't ignore it.
78* ImYourWorstNightmare: His quote when first introducing himself and the others as N-Men.
79-->'''Jimmy:''' Who am I? I'm your worst nightmare.
80-->--later...--
81-->'''Cindy:''' By the way Neutron, who said you can issue a corny battle cry and where do you come up with N-Men?
82* InnocentBlueEyes: Has dark blue eyes which represent his heroism and brainy nature.
83* InnocentProdigy: He's a genius when it comes to science and technology, but he's also extremely naive and childish, even for his age. A lot of plots are set in motion because his ability to invent vastly outstrips his ability to understand the consequences.
84* InsufferableGenius: He does try to be modest (even creating a device to measure arrogance), but he's legitimately so much smarter than a lot of people that it's difficult for him. This escalates when Cindy is around (who used to be the smart girl).
85* IntelligenceEqualsIsolation: {{Downplayed|Trope}}. Jimmy's intelligence isolates him, he often sets the (horrible) events of the plot in motion, causing him to be isolated, sometimes the characters realize they need his intellect and/or like him more than they let on, and sometimes he's just an insufferable genius. That said, unlike a lot of examples of this trope, he has a consistent, mutually beneficial friend circle and can actually interact with people without freezing up.
86* ItsAllMyFault: For all his InsufferableGenius and DisproportionateRetribution moments, not once was there ever a single moment where he would [[NeverMyFault refuse to take responsibility for his actions or even flat-out try to downplay them]] whenever his inventions would cause some sort of catastrophe at worst, and more often than not he is willing to clean up the mess he made himself.
87* JerkassHasAPoint: As snobby as he can be, Jimmy's claims on certain things can be legitimate.
88* JerkWithAHeartOfGold: Jimmy tends to be arrogant, condescending, and snarky, creating various inventions for his own selfish intentions. However, in the end, he's well-meaning and does care about his friends and parents and at the end of the day, always saves the world.
89* KidHero: Jimmy is only an elementary school student but always saves the day from trouble, albeit caused by his own mistakes.
90* LackOfEmpathy: Downplayed. Jimmy is often is blind to other people's feelings, no matter how obvious they may be. It's no wonder why he's better at making enemies than friends. That said, he usually is willing to fix whatever problems he made and his occasional callous nature isn't from malice but a lack of social skills.
91* LittleProfessorDialogue: Well, he does actually have an IQ of ''210''.
92* MrViceGuy: He does cause just as much problems as he fixes, and he isn't above rubbing his intelligence in some of the kids' faces (mainly Cindy's), but for the most part, he's a good kid whose heart is definitely in the correct position.
93* MyGreatestFailure: Establishing contact with the Yokians remains his biggest regret in life.
94* NerdsLoveToughSchoolwork: Completely averted - in fact, Jimmy hates school, just like any normal American kid.
95* NiceJobBreakingItHero: 99 out of 100 times, his inventions end up causing problems for everyone in Retroville, leading him to fix what he broke. As revealed in one episode, the majority of the Neutron extended family views him as the BlackSheep as a result (at least until he saves them from the new one... his EvilGenius baby cousin). In "The Incredible Shrinking Town", Libby remarks that Jimmy's endangered the town so often that she's just StoppedCaring.
96* NiceMeanAndInBetween: The Mean to Carl's Nice and Sheen's In-Between. He's an InsufferableGenius to the highest degree whose inventions often lead to the problem of the week.
97* NoSocialSkills: As a result of his smarts, he doesn't get people. He keeps really trying to improve on these.
98* OddFriendship: A boy genius whose closest friends are: an asthmatic hefty boy who's obsessed with llamas, a hyperactive Hispanic kid who's obsessed with a superhero, his academic rival/biggest bully/love interest & said rival's music loving sassy best friend.
99* PetsHomageName: Jimmy designed and built his robot dog and named him Goddard in honor of rocket science physicist and inventor Robert Goddard. Especially apt when, in his first animated feature film, Jimmy is able to ride upon Goddard like a space bike.
100* {{Pride}}: He can often be arrogant and overconfident.
101* PrimaryColorChampion: Jimmy wears blue jeans and a red shirt with a yellow atom on it, and is the main hero of the series. Fittingly, to contrast with [[SecondaryColorNemesis Cindy]], Jimmy's favorite colors are the three primary colors: red, blue and yellow.
102* ProperlyParanoid: He knew better than to trust the Yolkians in "The Eggpire Strikes Back".
103* PuppyLove: With Cindy. Their roles ping-pong back and forth depending on the episode, but the general tone of their relationships is that they each have a crush on each other, but are too immature to act on it.
104* ReedRichardsIsUseless: It's shown that he's capable of inventing technology that could absolutely revolutionize the world, but he's just a kid, so he only uses them for trivial and frivolous reasons. Shown most egregiously with his "I Can't Believe It's Not Oil" machine, which composts trash into a clean-burning oil substitute and nets him a Nobel Prize. All Jimmy cared about was that he wasn't allowed to enter it in his school's science fair, and Hugh's the one who had the wherewithal to submit it to the Nobel Committee. Luckily, he eventually grows out of it (see below).
105* RidiculouslySuccessfulFutureSelf: In the 'good future' of ''The Tomorrow Boys'', Jimmy is the first person to ever win the Nobel Prize in bulk. However, that was just a prediction, only Jimmy can make it happen.
106* ScienceHero: He embodies this trope for kids' shows, along with [[WesternAnimation/DextersLaboratory Dexter]].
107* SesquipedalianLoquaciousness: A frequent user and abuser of advanced vocabulary.
108* SlapSlapKiss: With Cindy. They have a pretty heated rivalry that is punctuated by occasional affection that is heavily implied to be romantic.
109* SmallNameBigEgo: Jimmy has a little bit of {{Pride}} despite the fact that [[BornUnlucky his inventions usually go wrong and/or cause trouble]], the fact that [[AllOfTheOtherReindeer nobody likes him or treats him properly]] (to say the very, ''very'' least), and the fact that he's not very talented or skilled in other things besides science, building machines and gadgets, and having intellect (but even then, [[DitzyGenius he doesn't have much common sense]]).
110* SymbolMotifClothing: His trademark atom emblem, which appears on the front of his shirt and nearly anything he invents.
111* StrongGirlSmartGuy: The Smart Guy to Cindy's Strong Girl. Cindy is smart but less of a ChildProdigy than Jimmy (a fact she resents), however she's more athletic than him and knows martial arts.
112* TerribleArtist: While Jimmy is a scientific genius, he's absolutely atrocious in almost every field of the arts. His drawing skills are barely better than stick figures, his musical talent got him 8th place in a talent show with only seven acts, and his attempts at writing poems effectively inflicted a LogicBomb on some of his machines. The only art-related achievement he has that doesn't involve cheating with his inventions is the fact that he's a better singer than [[DreadfulMusician Sheen]].
113* TookALevelInDumbass: While still a genius in his own right, he tends to let his overconfidence and arrogance get the best of him quite a few times.
114* TookALevelInJerkass: In the spin-off TV show, he's more arrogant, show-offy, condescending, and selfish (albeit [[JerkWithAHeartOfGold with a considerable good side]]). In the third season, however, he's much more abrasive and hostile. One could imply it's the result of having to deal with a lot of arch-foes and issues.
115* TooQualifiedToApply: In "The Science Fair Affair", Principal Willoughby decides that Jimmy's high IQ and scientific knowledge gives him an unfair advantage over the other students, so he bans him from participating in future science fairs to give other kids a chance.
116* TVGenius: He's a boy genius who is not only excessively prone to TechnoBabble and SesquipedalianLoquaciousness, but has invented time travel, faster-than-light warp engines, and the best candy in the history of all existence and everything.
117* TheUnapologetic: Whether Goddard suggests that Jimmy should apologies to his parents, Jimmy will always dismiss it out of his arrogance, as he thinks being a genius makes him always in the right. It normally takes some event to [[HumblePie make him apologize]].
118* VocalEvolution: In the pilot, the shorts and the movie, you'll notice that his voice was more nasally, scratchy and high pitched to match his dorky personality and sounded a lot more like [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy Nergal Junior]]. Now his voice is more deep and clear.
119* WithFriendsLikeThese: Downplayed. Jimmy isn't a bad friend to Carl and Sheen, but he has used Carl as a guinea pig for many of his inventions with little concern for his friend's well-being in order to balance out Carl's own questionable treatment of Jimmy countless times.
120* WorldsSmartestMan: Jimmy is considered the smartest human.
121* YankTheDogsChain: One of Jimmy's signature flaws. When some of his inventions start off good, they backfire on him right afterward.

123
124[[folder:Carl Wheezer]]
125[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/carl_85.png]]
126->'''Voiced by:''' Creator/RobPaulsen, Creator/WallyWingert (Jimmy Neutron Boy Genius console game)
127
128-->'''Full Name:''' Carlton Ulysses Wheezer
129
130Jimmy's shy, timid, nervous, and asthmatic best friend who has an unhealthy obsession with llamas and Jimmy's mom.
131----
132* AbnormalAllergy: Carl has a ridiculous number of allergies, as do his parents. His father is once shown to have an allergy to ''ice'' of all things.[[labelnote:Explanation]]It's rare, but quite possible for people to be allergic to water, so it's not as big of a stretch as you might think.[[/labelnote]]
133* AccidentalHero: In "The Great Egg Heist", he accidentally mixes up the real jade egg with the fake decoy one after the inferred lasers trigger his allergies, and he ends up putting the real one back. This ends up saving everyone when Professor Calamitous tries to use the egg as a power source for his doomsday device, but the fake egg causes it to meltdown and explode. To be fair to Carl though, he knew there was a chance he mixed the eggs up and tried to warn Jimmy, but Jimmy [[NotNowKiddo constantly ignored him]].
134* BigEater: You'd think having so many allergies would limit this, but no. Carl can chow down with the best of 'em and has a stomach of steel. Occasionally overlaps with ExtremeOmnivore for laughs:
135-->'''Sheen:''' Carl, you're supposed to play with the toys in the silly meals. Not eat them.
136-->'''Carl:''' I know. But they always look so colorful and chewy.
137* BigThinShortTrio: The Big to Sheen's Thin and Jimmy's Short.
138* BlackBeadEyes: He's the only character in the show to have these.
139* BringMyBrownPants: Carl has a tendency to soil himself.
140-->'''Carl:''' Mrs. Neutron, may I use your restroom? Because I really have to... never mind.
141* ButtMonkey: He's the Guinea pig to all of Jimmy's experiments. He's also the butt of gags such as him accidentally spraying his eyes with his inhaler.
142* CannotKeepASecret: Whenever somebody has something they want hidden from others that Carl is in on, he always blurts it out. Make a second lunch so you still have one when a bully takes your first, Carl points it out and the bully destroys it. Take your friends to Egypt without the teachers noticing, Carl tells them the moment you get back. Disguise a brain drain helmet as a crown to save somebody who can read thoughts with the gained intelligence, Carl basically says exactly what they are doing in his head.
143* CatchPhrase: [[OwMyBodyPart "My scapula..."]]
144* CharacterizationMarchesOn: He eventually goes from being Jimmy's shy, asthmatic and introverted best friend to a more whiny and childish person.
145* CowardlySidekick: Carl is much more introverted than his fearless best pal, Jimmy.
146* TheDitz: In one episode, when Jimmy and Sheen shrink down and enter Carl's body. They enter his skull and get a close look at Carl's brain, it's so small that Sheen mistakes it for a walnut at first[[note]]The gag comes up again in another episode where he, Jimmy, and Sheen get an X-ray that shows their brains. His brain is far tinier than the others[[/note]].
147* DubNameChange: The Brazilian Portuguese dub changes his given name to "Caio", a notable Portuguese given name, as a form to make the public remember his name more easily.
148* DumberThanTheyLook: Carl Wheezer, despite having the big glasses, [[GeekPhysique portly physique]] and breathing problems of a prototypical nerd, is only marginally smarter than resident {{Cloudcuckoolander}} Sheen, the episode "The Junkman Cometh" implying that he's even ''dumber'' when the titular Junkman scans their brains. [[LampshadeHanging Lampshaded]] on "Birth of a Salesman" when Jimmy's robot salesman says that Carl looks like a smart guy, and Carl remarks "Nuh-uh, it's just the glasses".
149* EarlyInstallmentCharacterDesignDifference: Downplayed example. Carl stopped wearing suspenders after the movie.
150* ExtremeOmnivore: He eats newspapers and toys.
151* {{Fartillery}}: Gets this in "The N-Men" (see {{Gasshole}} below).
152* FatBestFriend: Generally a straight mixture of a Type C (though not as big of a {{Cloudcuckoolander}} as Sheen) and a Type B (being shy). Which one dominates depends on the episode.
153* FatIdiot: To say the very least, he's overweight and isn't very bright.
154* {{Gasshole}}: He has burped more than anyone else on the show (except for Jimmy's dad). In "The N-Men", he gets hit by some cosmic radiation that turns him into "Belch Boy", allowing him to unleash [[MakeMeWannaShout sonic blast]] burps by drinking seltzer or shaking himself really hard.
155* GreenEyedMonster: It is shown in "I Dream of Jimmy" and "Carl Wheezer, Boy Genius" that [[IJustWantToBeYou he'd really like to have Jimmy's life]].
156* HollywoodToneDeaf: His most attempts at singing something.
157* {{Hypocrite}}: Out of the entire trio, he is the one most outspoken about how boys should not take interest in girls, even though he has hots for them just as often as Jimmy and Sheen do.
158* ItRunsInTheFamily: His allergies. Turns out his mother and father have various allergies too.
159* InnocentlyInsensitive: Carl tries to give Jimmy a pep talk, but only says something that makes him upset.
160* JerkassBall: Carl takes it in "Carl Wheezer, Boy Genius", which starts out as a standard "I lied to my pen pal" farce, then quickly escalates as we learn Carl lied about having ''Jimmy's'' life. It goes downhill as Carl not only has to masquerade as a boy genius, but he forces Jimmy to be his lowly assistant, or as Carl would put it: "My dimwitted assistant", which seems out-of-place for him to even say. Then Carl starts milking the moment by blaming him for everything. Even by the end, when Jimmy has saved his life at least three times, Carl is ''still'' blaming him and projecting his own insecurities onto Jimmy to boot.
161* LikesOlderWomen: Carl has a crush on Jimmy's mom since ''Love Potion #976-J''. He's also attracted to the class' teacher, Miss Fowl, who's in her fifties. At ''least'' and Beautiful Gorgeous too.
162* LooseLips: Sheen helps him a lot with this one. They're often the ones to reveal the secret plan to the enemy, generally via SuspiciouslySpecificDenial.
163* MinorInjuryOverreaction: Even the smallest tap on any part of his body will cause him great physical pain. He pretty much inherits this from the rest of his family as well.
164* NerdGlasses: Wears a pair of big glasses.
165* NerdyInhaler: Carl uses an inhaler very frequently and is also allergic to almost everything.
166* NervousWreck: He's a bundle of nerves constantly, due primarily to his weak constitution and nearly universal allergies.
167* NeverMyFault: He gives this treatment to Jimmy in "Attack of the Twonkies" and "Carl Wheezer: Boy Genius".
168* NiceGuy: Despite his shyness and rather eccentric personality, he's still among the nicest of all the main characters.
169* NiceMeanAndInbetween: The Nice to Jimmy's Mean and Sheen's In-Between. He is always willing to help out Jimmy despite knowing his inventions could be dangerous on him.
170* OwMyBodyPart: He seems to have a really tender scapula.
171* PrecociousCrush: He has an ongoing crush on Jimmy's mom.
172* ProneToTears: For a fat guy, Carl is very thin-skinned.
173* ShrinkingViolet: He's generally shy and nervous, at least before his Flanderization.
174* SensitiveGuyAndManlyMan: The shy, cowardly Sensitive Guy to Sheen's superhero-obsessed Manly Man.
175* SicklyNeuroticGeek: What else can you expect with a surname like 'Wheezer'?
176* StalkerWithACrush: He becomes one to Jimmy's mom after being sprayed with Jimmy's love potion.
177* UngratefulBastard: In "Carl Wheezer: Boy Genius", Carl steals Jimmy's life and constantly puts everyone in danger. Every time Jimmy saves him, Carl totally blames Jimmy and constantly treats him like a slave.
178* VoiceChangeling: In "The Incredible Shrinking Town", It was said he could do this from a ventriloquism lesson. The result was awesome. He was capable of impersonating Cindy's Mom's and Zix's voice perfectly.
179* VocalEvolution: In the pilot, shorts, movie and early episodes, his voice was more deep, nasally, and melancholy.
180* WithCatlikeTread: Carl seems to think he needs to loudly sing a theme song whenever he is working as a spy, which is the opposite of what a spy should do.
181* WithFriendsLikeThese: He and Sheen can act like this way towards Jimmy by laughing with Cindy and Libby when they bully him. Jimmy once told him and Sheen not to tell the other kids about his weather invention going haywire, but they told the kids anyway, causing said kids to be (albeit understandably) angry with Jimmy (though Carl justifies that this was due to peer pressure). Jimmy has, however, used Carl countless time as a guinea pig for his invention, so it pretty much balances out.
182* YouthfulFreckles: Has many freckles that match his red hair.

186[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/sheen_jimmy_neutron.png]]
187->'''Voiced by:''' Creator/JeffGarcia
188
189-->'''Full Name:''' Sheen Juarrera Estevez
190
191One of Jimmy's best friends who is obsessed with the fictional superhero Ultra Lord. He's a hyperactive, stupid, eccentric, loud, energetic, and geeky Hispanic-American.
192----
193* AccentAdaptation: In the Latin American dub, he speaks with a Japanese accent, possibly because the translators thought that he's Japanese-American, instead of Hispanic, and his name should be pronounced "Shin". Funnily enough though, Sheen ''was'' supposed to be Japanese, but since nobody could do anything Japanese sounding, Jeff Garcia came in and he was made Mexican.
194* AmbiguouslyBi: Even though Libby tends to be Sheen's main love interest and is heavily attracted to Beautiful Gorgeous, he has also shown to show a bit of attraction towards Jimmy, Carl and Jet Fusion as well.
195* AttentionDeficitOohShiny: More or less made explicit in "Sheen's Brain", wherein his ability to learn is limited by his concentration difficulties and hyperactive demeanor. This is what basically dooms his chances to pass the test that'll secure him staying in sixth grade, prompting Jimmy to fix it scientifically (temporarily).
196* BadassBoast: In ''Sheen's Brain''.
197-->I control the wind, and I shall rain fire down from the heavens! Goodbye Sheen the overlord. [[AGodAmI Hello Sheen the God!]]
198* BerserkButton: Do NOT call Ultra Lord a doll. Or mock Ultra Lord in any way. And definitely don't mess with his precious Libby.
199-->'''Sheen:''' [[ComicallyMissingThePoint Guys, what're you so worried about? Ultra Lord's gonna be here any minute.]]
200-->'''Cindy:''' Ultra Lord's not coming you, ding-dong! The Yolkians lied to you!
201-->'''Sheen:''' '''[[BigWhat WHAT?!]]''' Then they have awakened the wrath of Sheen!
202* BetaCouple: With his sweet princess, Libby.
203* BewareTheSillyOnes: He actually cares about Libby more than Ultra Lord and was more than willing to fight Yoo-Yee to get her back.
204* BigThinShortTrio: The Thin to Carl's Big and Jimmy's Short.
205* BookDumb: An exaggerated example, given he's very incompetent in school, yet makes up for it with his encyclopedic knowledge of superheroes like Ultra Lord.
206* ButtMonkey: He suffers a fair amount of physical abuse. He is also sometimes used to test Jimmy's experiments, but he actually enjoys this.
207* CharacterExaggeration: Some people may not know this, but in the movie, he was fairly intelligent and less hyperactive. In Season 3, he's more loud and ignorant. In ''WesternAnimation/PlanetSheen'', all of his serious traits are totally erased; changing him from his nerdy and hyperactive self to an obnoxious prick.
208* CharacterTic: Tends to go cross-eyed whenever overexcited or shocked about something.
209* TheChosenOne: Sheen happens to be this for the monks of Shangri Llama, who regard him as "he who puts foot behind head".
210* {{Cloudcuckoolander}}: In a minor but interesting play-off of the idiot sidekick shtick. Sheen isn't exactly stupid (at least before Flanderization set in); he's just very, very scatterbrained.
211* ComicallyMissingThePoint: In "Maternotron Knows Best", Robot Judy gives Sheen and Carl application forms. Sheen's question is "Jimmy falls in the playground and breaks his leg. What do you do?" His response: "Well that's a stupid question. They don't even tell you which leg it is".
212* TheDitz: His IQ is 32. RuleOfFunny is presumably the only reason he's able to function ''at all''.
213* DrunkWithPower: When his intelligence is increased in "Sheen's Brain".
214* TheFriendNobodyLikes: Sheen constantly annoys everyone with his ramblings about Ultra Lord, low intelligence, annoying shouting and the fact that he can be insensitive. However, Jimmy and Carl still consider him to be a good friend and the three of them are quite close.
215-->'''Sheen:''' Hey Robot! If the Junkman turns your parents into gravadiscs, can I have one?
216-->'''Jimmy:''' Sheen!
217-->'''Sheen:''' But they look so cool.
218-->'''Robot:''' [to Carl] I don't like Sheen.
219-->'''Carl:''' Tell me about it.
220* GeniusDitz: It should be noted that he seemingly on his own created an entire website dedicated to Ultra Lord at a time when doing such a thing required some programming knowledge. Said website claimed Ultra Lord was the father of America (and the whole planet).
221* GoofyPrintUnderwear: Limited Edition Ultra Lord Underwear! Only available in Japan!
222* HeldBackInSchool: It's revealed in "Operation: Rescue Jet Fusion" that he's been in the same grade as his friends for two years.
223* HiddenDepths:
224** Despite scoring a [[EpicFail quadruple F-minus]] on a U.S. history exam, in "Who Framed Jimmy Neutron", he is aware that Jimmy Carter is the 39th President of the U.S., showing that he has at least some educational knowledge of U.S. history.
225** He has a one-off line about how he, "sabatoged [his] highly scientific brain early on with cartoons and sugar" to avoid the struggles of being a genius. Essentially he pulled a less-sci-fi version of Jimmy's brain-drain helmet scheme.
226** In "Who Framed Jimmy?", Sheen mentions he's taken bear-wrestling classes, as he was able to wrestle a entire ''wild grizzly bear '''without a scratch on him'''''.
227---> '''Sheen:''' Man, those bear-wrestling classes my dad made me take sure paid off.
228* HollywoodToneDeaf: His singing is so bad, it actually puts the music-hating Twonkies to sleep.
229* InnocentlyInsensitive: Thanks to his short attention span and low intelligence, Sheen tends to say very insensitive things to Jimmy and Carl.
230* JerkassBall:
231** In "Sheen's Brain", he becomes arrogant and rude towards everyone after becoming a genius and that's before he gains telekinetic powers, plots to plunge all of Retroville into darkness and sadistically tortures Jimmy and Carl. When he brutally strikes them with a lightning bolt, [[HeelRealization he realizes his new powers have turned him into a monster and decides to go back to normal]]. This also counts as TemporarilyAVillain.
232** In "Jimmy for President", Sheen blackmails Carl with an embarrassing photo from Ike's birthday party if he doesn't vote for him. When Sheen's plot is exposed, he is disqualified from the election (along with Jimmy and Libby for the same reasons).
233** Sheen is often insensitive to people's feelings, though it alternates between his being too scatterbrained to pick up on emotional ques or too thick-skinned to take much note of them.
234* JerkWithAHeartOfGold: Sheen has a habit of being arrogant, insensitive, and obsessed with his self-interests, especially his obsession with Ultra Lord. He is still supportive and loyal to his friends and seems to love Libby and his dad.
235* {{Keet}}: He's very energetic.
236* LargeHam: Pretty much. He has absolutely NoIndoorVoice, always yells unnecessarily, and behaves in a very over-the-top, overly energetic demeanor. He also has some dramatic moments, like in the ''Jimmy-Timmy Power Hour'' when he finds out that [[WesternAnimation/TheFairlyOddParents Timmy Turner]] isn't Jimmy.
237-->'''Sheen:''' SHE'S A WITCH I TELLS 'YA!! BURN HER! ''BURN HER!!''
238* LoonyFan: He's obsessed with cartoon superhero Ultra Lord.
239* MetaGuy: A RunningGag in the later seasons has him predict that an adventure is imminent before any of the other characters even get to that point (so much so that him saying, [[SharePhrase "To the lab!"]] early becomes kind of a catchphrase). In ''Stranded'', for example, he can tell it just from the fact that Jimmy and Cindy are arguing:
240-->'''Sheen:''' Just a little longer, Carl. Our adventure should start at any minute.
241-->'''Carl:''' What adventure?
242-->'''Sheen:''' You'll see...
243* MiseryTrigger: He can't stand the thought of Ultra Lord being cancelled.
244* MissingMom: According to the creators, she died when Sheen was too young to remember her.
245* NiceMeanAndInbetween: The In-Between to Carl's Nice and Jimmy's Mean. He's the wackiest and most high-spirited guy of the group, but does have a bit of an ego like Jimmy and tends to be a bad friend in certain circumstances.
246* NoIndoorVoice: Sheen yells all the time, especially in Season 3.
247* OddCouple: Him and Libby. He's so HollywoodToneDeaf the Twonkies were unaffected and she's the biggest music geek in town.
248* PluckyComicRelief: He serves as the funny sidekick on the show.
249* PuppyLove: With Libby. It's actually somewhat more explicit compared to Cindy and Jimmy, largely because Libby is more emotionally mature and Sheen is more open about his feelings.
250* RedOniBlueOni: The hyperactive, energetic red to Nick's savvy, jaded blue.
251* SensitiveGuyAndManlyMan: The superhero-obsessed Manly Man to Carl's shy, cowardly Sensitive Guy.
252* TheSlacker: Watches Ultra-Lord while trying to do his homework.
253* TeachersUnfavoriteStudent: Miss Fowl has a particular dislike towards him due to his obsession with Ultra Lord, to the point where [[ShowAndTellAntics he showed off his action figure of him for show and tell seven weeks in a row]], and because he is extremely BookDumb, to the point where he once scored a [[FMinusMinus F----]] on a test (one of his answers was that Ultra Lord was the father of the United States, which was on the official Ultra Lord website). She is also not above insulting [[HollywoodToneDeaf his terrible singing voice]], to the point where after she gives him a solo in the school choir to thank him for saving the town from the Twonkies (since they like terrible music but hate good music), she locks him in a sound-proof booth. In "Journey to the Center of Carl", when all of her students are too sick to go to school thanks to Jimmy's sick patches, she admits that she misses all of her students, except for Sheen.
254* TooKinkyToTorture: Sheen seems to get a kick out of being electrocuted. In "Krunch Time", after Carl gets electrocuted trying to remember which door has cheese behind it, Sheen is eager to take his turn just so he can touch "the shocky door" again. At the end of the episode, when Jimmy sabotages his perfect candy by having it electrocute people, [[OnlyOneFindsItFun Sheen is the only one who enjoys it]]. At the end of "Who's Your Mommy?", he, Jimmy and Carl go to Planet Shmengy to celebrate the birthday of Shmengo, Carl's adopted son who's an alien jellyfish. After Carl gets electrocuted from hugging Shmengo, Sheen hugs Shmengo and gets electrocuted as well. He then hugs Shmengo a second time just so he can get electrocuted again.
255* VibrantOrange: Sheen is very loud and peppy. As Vibrating Lad, he wears an orange costume.
256* VibrationManipulation: In "The N-Men", Jimmy and his friends are exposed to cosmic radiation that grants them superpowers. Sheen, who was in a vibrating massage chair during this incident, gains the ability to vibrate and move at super speed. Appropriately, he takes the codename "Vibrating Lad".
257* VocalEvolution: In the film, his voice is deeper, and he's less prone to over-the-top outbursts. In the TV series, it's noticeably higher and he's more consistently hyperactive.
258* WeWantOurIdiotBack: In "Sheen's Brain", Sheen is in danger of being held back in school after failing a recent history test, requesting Jimmy to create a device to greatly boost Sheen's IQ. While great at first, Sheen rapidly becomes more intelligent and arrogant as time passes, to the point where he develops psychic powers and declares himself a god. However, after realizing that he hurt Jimmy and Carl who were trying to help him before his head explodes, Sheen chooses to willingly decrease his IQ to turn himself back into his idiot self, apologizing for his actions.
259* WideEyedIdealist: He believed that there was goodness in Tee and was proven right.
260* WithFriendsLikeThese: He and Carl can act like this way towards Jimmy by laughing with Cindy and Libby when they bully him. Once, when Jimmy told him and Carl not to tell the other kids about his weather invention going haywire, they told the kids anyway, causing said kids to be (albeit understandably) angry with Jimmy.
261* WithGreatPowerComesGreatInsanity: When he becomes a genius, he gains telekinetic and psychic powers and plots to destroy all of Retroville. Not to mention he nearly kills Jimmy and Carl.

264[[folder:Cindy Vortex]]
265[[quoteright:177:https://static.tvtropes.org/pmwiki/pub/images/cindyart_1.png]]
266->'''Voiced by:''' Carolyn Lawrence
267
268-->'''Real name:''' Cynthia Aurora Vortex
269
270Jimmy's rival and female counterpart, who has a crush on him. Not that she'll admit it.
271----
272* AbusiveParents: Somewhat ambiguous. Mrs. Vortex is portrayed early in the show as strict, snooty, and likely responsible for Cindy's ambition, competitiveness, the huge number of extracurricular activities, and her insecurities (Mr. Vortex is TheVoiceless and mostly a nonentity where the stories are concerned). That said, [[CharacterizationMarchesOn she was portrayed more kindly]] in later episodes, to the point that in "Win, Loose, Kaboom", she is [[MamaBear the first to suggest that the Retroville parents start working on helping their children instead of just standing and watching]]. Both [[WesternAnimation/JimmyNeutronBoyGenius the movie]] and [[VideoGame/JimmyNeutronBoyGenius its video game adaptation]] confirm that the Vortex family members genuinely love each other.
273* AcademicAlphaBitch: She lost her reputation as the smartest kid at her old school when she moved into the house across the street from Jimmy, whereupon Cindy, now runner up, began a rivalry with him.
274* AcademicAthlete: The smartest student after Jimmy and knows karate enough to kick asses.
275* ActionGirl: Cindy practices karate.
276* ActorAllusion: Cindy isn’t the first [[WesternAnimation/SpongeBobSquarePants book-smart, highly competitive, and martial arts practicing character]] voiced by Carolyn Lawrence.
277* AesopAmnesia: How many times has Cindy learned not to take her friends for granted or act obnoxiously clingy towards Jimmy or give into false flattery?
278* AttentionWhore: Cindy feels the need to constantly remind everyone of how "beautiful, talented, and perfect" she is.
279* BadassAdorable: A young girl who's also a skilled martial artist.
280* BadassBookworm: Other than being the second smartest kid in town, Cindy is more athletic than Jimmy, who is a regular {{Bookworm}}, and practices a lot of martial arts sports.
281* BadLiar: Cindy is the worst liar in the world.
282* BecauseYouWereNiceToMe: Cindy holds a particular fondness towards [[WesternAnimation/TheFairlyOddparents Timmy Turner]] because he actually treats her with respect. Even after learning Timmy lied to her about being a genius so she could like him, she still considers him a decent guy because he was genuinely sorry about it.
283* CannotSpitItOut: Cindy's extremely cautious when it comes to saying things she might regret afterward so she usually avoids it when she can. And when she knows she should apologize to Jimmy or otherwise acknowledge his intellect or skill, it's bound to come out after a prolonged period of awkward silence or "Neutron, I hate to say it but...". Obviously applies to revealing her true feelings about him as well.
284* ChicAndAwe: Cindy complains about Jimmy being best man at Jet Fusion's wedding to Beautiful Gorgeous in "My Big Fat Spy Wedding", only to stop stunned as Jimmy shows up in a handsome tux. [[WomenAreWiser Libby]] has to snap her out of it.
285-->'''Cindy:''' So Neutron's the best man? Yeah, more like the best NERD! I bet he'll look like a total... ''(Jimmy shows up outside the church in a tux. Cue fade to pink background, [[WingdingEyes eye-hearts]] and hair patting)'' ...HUNKMUFFIN.
286* ClingyJealousGirl: She doesn't like seeing Jimmy showing any interest in other girls, most notably Betty.
287* TheCorruptible: She tends to get easily flattered by the villains into helping them, mostly to spite Jimmy.
288* DeadpanSnarker: She's often prone to sassy remarks.
289** For example "Beach Party Mummy" has this exchange:
290-->'''Jimmy:''' I don't understand it. I can't seem to find the lost tomb!\
291'''Cindy:''' Duh! That's why they call it the "''lost'' tomb", not the "here it is tomb, come inside and have a milkshake"!
292* DefrostingIceQueen: Towards Jimmy over the course of the show, as her affection towards him becomes more evident.
293* DependingOnTheArtist: Oddly, she has two distinct designs depending on the media she's in. Her movie design gave her a pink shirt and pigtails, while the show redesigned her to wear a green tank top and a ponytail. Despite her show redesign being established early on, various tie-in games retained the original movie design to the point where it makes up the majority of her video game appearances, and she ironically wouldn't use her show design in games until after the show already ended (such as in ''[[VideoGame/NicktoonsUnite Globs of Doom]]'' or ''VideoGame/NickelodeonKartRacers 3'').
294* {{Expy}}: Of [[WesternAnimation/HeyArnold Helga Pataki]]. Both of these tomboyish blonde lasses each harbor crushes on the main protagonist, but act antagonistic and bully them whenever they're present in order to hide it. Cindy even resembled Helga quite a bit in the early shorts and the pilot movie, sporting two pigtails and wearing a pink shirt similar to Helga's pink and white dress. Her altered appearance in the series proper was likely done to differentiate her from Helga.
295* {{Flanderization}}: In the movie, she was revealed to be a lot kinder than she seemed and she and Jimmy got along better as a result by the film's end. In the series, she's become more stubborn and she and Jimmy fight more.
296* GeniusBruiser: Though not as intelligent as Jimmy, Cindy is still [[BadassBookworm smart in her own right]] and is also a skilled martial artist.
297* GirlishPigtails: In the movie and shorts before trading it to a ponytail.
298* GoofyPrintUnderwear: Polka dot panties.
299* GreenAndMean: She often wears a green outfit and is quite sassy and condescending towards others (especially Jimmy).
300* GreenEyedMonster: Does the trope both figuratively and ''literally'' (with ''actual'' green eyes).
301** She was the smartest kid in her old school until she moved into town and met Jimmy.
302** It is also shown that she is jealous of Betty Quinlan, and not just because Jimmy likes her.
303** In "Beach Party Mummy", she suspiciously asks "What's going on?" when Jimmy [[HoldingHands holds Libby's hand]] (after he figures out that she can trick the mummies into sparing them due to being a descendant of a female Pharaoh).
304* HintDropping: Unfortunately, Jimmy seems to permanently be holding the IdiotBall when it comes to interpersonal relations.
305* HollywoodGenetics: She has blond hair and green eyes. Neither of her parents are blond (Her mom has black hair and her dad has brown hair) and her father's brown eyes would likely have dominated her mother's green eyes.
306* IdiotBall: Whenever the villains try to manipulate her into helping them with false flattery.
307* IJustWantToBeSpecial: She actually admires Jimmy, is very fond of him and secretly wants to be as brilliant and smart as him. Also counts as InferioritySuperiorityComplex.
308* ItsAllMyFault: In "The N Men", when she realizes that her mistreatment towards Jimmy has turned him into a hulking jerk monster.
309* JerkassHasAPoint: Cindy is not entirely wrong about Jimmy always causing trouble for the town (and sometimes, the world) and always points out the flaws in his "brilliant plans". In "The Science Affair", although more to make herself win, she's not entirely wrong that [[ChildProdigy Jimmy]] should no longer be permitted to participate in school science fairs since he wins ''every year'' and is the therefore TooQualifiedToApply.
310* JerkWithAHeartOfGold:
311** Cindy is bossy, spoiled, stubborn and self-centered, but underneath all that, she is a genuinely good person, but doesn't want anyone to know that.
312** She is deeply infatuated with Jimmy, looks up to him and wants to be as brilliant as him. This is pretty much the main reason why she always tries to poke fun at him or otherwise make him angry. [[BelligerentSexualTension Works both ways.]]
313** She enjoys taking care of pets, plants and little babies.
314** She doesn't like it when Jimmy is emotionally crushed, heartbroken or depressed and usually goes to comfort him.
315* JerkWithAHeartOfJerk: In "Who Framed Jimmy", she doesn't care that Jimmy has been sent to prison and tries to turn him in to get the reward money.
316* KungFuKid: Cindy practices karate. She goes to competitions, is sometimes seen in her gi, and although we're never told what level she's at, based on some of her flips, she's probably a black belt.
317* LaserGuidedKarma: In the ChristmasEpisode "Holly Jolly Jimmy", she and Libby get coal for Christmas as punishment for turning Retroville against Jimmy after he accidentally ruins Christmas by scrambling SantaClaus' atoms. It helps that Jimmy did his best to fix his mistake and that Cindy and Libby kept on ragging on Jimmy even after he apologized for his blunt arguments that Santa doesn't exist.
318* LastNameBasis: Even though she uses Jimmy's first name plenty of times, she often calls him by his last name (or the "Nerdtron" nickname she came up with) and even when she warms up to him towards the end of the show, it's not usual to hear a "Jimmy" coming out of her mouth, possibly because old habits die hard or possibly because he's gotten a bit more irritable around her. In all fairness, Jimmy himself does call Cindy "Vortex" every once in a while, mainly when he's annoyed.
319* LaughOfLove: She sometimes laughs when she's having romantic moments with Jimmy, most notably in the episodes "Love Potion 976/J" and "Stranded".
320* LittleMissSnarker: In "Trading Faces":
321-->'''Jimmy in Cindy's body:''' Don't give Cindy my astounding ability to create and build pioneering technologies, okay?\
322'''Cindy in Jimmy's body:''' Oh yeah, like I'd want to invent a toilet in a briefcase!
323* LovingBully: She picks on Jimmy but she only does this to mask her love for him.
324* NeverMyFault: She gives this treatment to her friends when ''she'' causes the problem. Particularly in "Vanishing Act", which Jimmy understandably calls her out on.
325* NiceJobBreakingItHero:
326** In "The Eggpire Strikes Back" she tells King Goobot how to get inside Jimmy's lab after learning it from Carl and Sheen. Partly subverted since for all she knows they just want to help her in being able to compete with Jimmy on an equal footing by means of building a lab of her own, though she's dumb enough to trust the Yolkians (and so is everybody else in town, except Jimmy). When she realizes that her actions put the whole Retroville in danger, she is the first to call on the others to believe Jimmy and help him bring down Poultra.
327** "The N Men" has her acting uncharacteristically harsh to Jimmy and she refuses to listen to his warnings about misusing her powers. Fed up with Cindy's nasty attitude and how she treated him, Jimmy transforms into a hulking jerk monster. When she sees that the army is after him, she realizes that this is all her fault and decides to make amends by helping him. Later as she's falling unconscious, she gets down on her knees and apologizes to Jimmy for hurting his feelings and attempts to tell him how she really feels, changing Jimmy back to normal.
328** "Vanishing Act" has her resentment towards Betty going critical and she causes Jimmy's magic box to overload and send herself, Betty, Carl, Jimmy and Sheen into some strange world. Jimmy ''finally'' gets the pleasure to call her out for it.
329** In "Normal Boy", Cindy coldly tells Jimmy to leave for college already because she's so jealous of Jimmy always stealing her thunder at Show-and-Tell. Because Jimmy took this criticism to heart, he dumbs himself down (literally, using a brain drain helmet) just when he's needed to deflect a meteor headed for Retroville, forcing Cindy to help Jimmy regain his intelligence.
330** "King of Mars" has her defecting from the gang to join Eustace. Again, subverted because the only reason why she does it (and the very argument Eustace uses to convince her) is to make Jimmy finally take notice of her, even though she was TooDumbToLive. That's also why she is EasilyForgiven later on.
331* NiceMeanAndInbetween: She's the Mean to Nick's Nice and Libby's In-Between. She always rebels against Jimmy, but slowly grows more affectionate to him over the course of the series.
332* OutOfCharacterMoment: In the ''WesternAnimation/FairlyOddParents'' crossover trilogy, she acts totally unrealistic and airheaded when Timmy is around and is blind to all of his lies and [[InsaneTrollLogic she even makes stupid assumptions]]. She doesn't even care that Jimmy and Timmy were practically killing themselves because of her.
333* PinkMeansFeminine: Wears pink sneakers and, as seen in the first episode, [[PantyShot light-pink panties]]. Also wore a pink shirt in the shorts and movie. She also decorates her room pink.
334* {{Pride}}: Like Jimmy, this is one of her trademark flaws. Cindy never admits her mistakes and always tries to find excuses to blame her friends.
335* PuppyLove: With Jimmy. It's framed by her dislike of boys in general and of Jimmy in particular because of his constantly showing her up, but several episodes show that she has a pretty huge crush on him.
336* TheRival: To Jimmy, primarily in academics, but also in everything else they can compete in.
337* RivalryAsCourtship: Jimmy and Cindy each have their own respective crushes in the beginning of the series (Betty and April for Jimmy, and Nick Dean and [[WesternAnimation/TheFairlyOddParents Timmy Turner]] for Cindy) while nursing their own rivalry with each other. By the end of the series though, it's clear [[OfficialCouple where their relationship stands]].
338* SecondaryColorNemesis: She is Jimmy's main rival and wears a green tank top, with her favorite colors consisting of green, purple and orange.
339* SlapSlapKiss: With Jimmy. In some episodes, they're bitter rivals. In others, it's PuppyLove.
340* SpoiledBrat: Cindy can be very bratty if she doesn't get what she wants.
341* StrongGirlSmartGuy: Strong Girl to Jimmy's Smart Guy. Cindy is smart but less of a ChildProdigy than Jimmy (a fact she resents), however she's more athletic than him and knows martial arts.
342* TankTopTomboy: Cindy wears a green tank top and is a PassionateSportsGirl who knows karate.
343* TomboyAndGirlyGirl: The Tomboy to Libby's Girly Girl. Downplayed in later seasons, but Libby is still into more "girly" pastimes like music and fashion, while Cindy is a PassionateSportsGirl with a tomboyish streak.
344* TomboyishPonytail: In the TV series. She has GirlishPigtails in the movie. Accordingly, she's more tomboyish in the former.
345* TomboynessUpgrade: From the movie to the series. While shown to be a good fighter during the climactic battle in the movie, the series [[TookALevelInBadass upgrades her skills]] to the point that she can compete even with a member of a warrior race of aliens, and in general puts more emphasis on her passion for karate. To match, she trades her GirlishPigtails for a TomboyishPonytail.
346* TrueCompanions: With Libby and Brittany.
347* {{Tsundere}}: Type A, obviously. In the movie she explains that she only became one to Jimmy because she was jealous of his better grades and she hates his tendency to show off his intelligence on every given occasion.
348* VocalEvolution: As the series went on, Cindy's voice got a bit harsher and she developed a slight Texan accent akin to that of [[WesternAnimation/SpongeBobSquarePants Sandy Cheeks]], another character voiced by Carolyn Lawrence.
349* WomenAreWiser: Every once in a while, especially seeing as Jimmy tends to lose sight of the bigger picture and waste time using his inventions even when simpler means would suffice. However, since she's at least just as stubborn as Jimmy, her taking the helm doesn't always prove to be the best idea either.
350* YankTheDogsChain:
351** In "The Science Fair Affair", she loses the trophy even after she helped save the day.
352** In "Win, Lose and Kaboom", April ruins her and Jimmy's big chance to kiss.
353** In "Attack of the Twonkies", after Jimmy and Sheen save the town, Sheen steals her spot in the school chorus.
354* YinYangBomb: Cindy tries to invoke this spiritually in the film by practicing Tai Chi while drinking purple flurp soda.
355-->'''Cindy:''' Tai Chi promotes wellness, relaxes, and rejuvenates the body. Whereas purple flurp, being ninety-eight percent sugar, creates tension and a temporary rush of energy and mood swings. I figure if I do both of them together, I achieve perfect balance.

358[[folder:Libby Folfax]]
359[[quoteright:191:https://static.tvtropes.org/pmwiki/pub/images/libby.png]]
360->'''Voiced by:''' Creator/CrystalScales
361
362-->'''Real name:''' Liberty Danielle Folfax
363
364Cindy's best friend and Sheen's love interest. The love of Libby's life? Music, the funkier the better. And she doesn't just listen, she also plays the keyboard, [=DJs=], and can throw a high note that would give most opera singers a run for their money.
365----
366* BetaBitch: She plays this role to her best friend Cindy.
367* BetaCouple: With Sheen.
368* BigSisterMentor: Libby serves as a big sister to Jimmy and is always trying to get him to come out of his shell.
369* CannotTellALie: Which usually makes it hard for her to keep secrets or for her to go with Jimmy's brilliant plans. However, Libby [[OutOfCharacterMoment does lie]] in "Jimmy for President" and "Attack of the Twonkies". Naturally, her friends are shocked by this.
370* CharacterDevelopment: Libby used to be more of a sidekick to Cindy, but she soon enough became more distinct and evolved into the group's DeadpanSnarker and [[OnlySaneMan most sensible and levelheaded member]].
371* CheatersNeverProsper: In "Jimmy for President", she tries to buy Carl's vote and even lies to him. At the end, Libby (along with Jimmy and Sheen) is disqualified from the election as a result.
372* CostumeEvolution: In a reverse of how Cindy originally sported a t-shirt to a tank top, Libby wore a sleeveless green dress for the movie and first season. After her haircut, Libby wears a pink shirt with blue jeans.
373* DeadpanSnarker:
374-->'''Sheen:''' Don't worry, Libby. When I'm elected, you can still be my First Lady.
375-->'''Libby:''' Get a life, Sheen.
376* FamousAncestor: In the Egypt episode, Libby discovers that she's the descendant of the Egyptian Queen [[PunnyName Hasabataslapya]].
377* {{Gasshole}}: Becomes one after eating the Belch Boy packet in "The League of Villains", even to the point of making a ''dance'' out of her burps.
378* GiveGeeksAChance: Both in telling Cindy to be honest with Jimmy and her own involvement with Sheen.
379* HiddenDepths: In "My Big Fat Spy Wedding", she has an official business performing at weddings and can even play the piano.
380* ImportantHaircut: Libby gets one in the ''Beach Party Mummy'' episode to fool a bunch of mummies that were chasing the gang. She keeps the new look for the remainder of the series.
381* IncrediblyLongNote: Turns this into a ChekhovsGun in "The Great Egg Heist".
382* {{Invisibility}}: She gained this power along with the ability to [[BarrierWarrior generate force fields]] in "The N-Men" episode.
383* JerkassBall: In "Lady Sings the News", Libby betrays her friends, exploits their secrets to the press and even blackmails people into waiting on her. Later, when she finds out the town is gonna kill Carl, she sees the error of her ways and apologizes to her friends.
384* NiceMeanAndInbetween: She's the In-Between to Nick's Nice and Cindy's Mean. She's not as mean as Cindy, but is more impulsive than Nick.
385* NotSoAboveItAll:
386** Just like Cindy does with her feelings for Jimmy, Libby sometimes denies her feelings for Sheen.
387** Sometimes, she is shown to like Ultra Lord as well.
388** When she gets her music taken from her, she starts sobbing like a baby.
389* OddCouple: Her and Sheen. She is the biggest music geek in town, he's so HollywoodToneDeaf the Twonkies were unaffected,
390* OOCIsSeriousBusiness: Whenever she lies. And if she stops listening to music, ''you know something is wrong''.
391* OnlySaneWoman: She's the most levelheaded character in the series (along with Judy).
392* PinkMeansFeminine: Her new design includes a pink long-sleeved shirt.

398* TomboyWithAGirlyStreak: She adjusts really quickly to becoming "Burp Girl" in "The League of Villains", even proving better at using the sonic-blast burps than Carl did in "The N-Men". She's sassy, loves hip-hop and electronic gadgets, and wears jeans (as opposed to the movie, where she has more a GirlyGirl design), but she also likes fashion and has a pink shirt.
399* TrueCompanions: With Cindy and Brittany.
400* WomenAreWiser: Compared to her boyfriend, Sheen.

403[[folder:Goddard]]
404[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/goddard.png]]
405->'''Voiced by:''' Creator/FrankWelker
406
407Jimmy's robot dog and lab assistant.
408----
409* BadassAdorable: Goddard's appearance, loyalty, and playful nature is just adorable. He's also tech-savvy and very useful when he is needed at any time.
410* BenevolentAI: Goddard is by far the only robotic invention of Jimmy's who hasn't gone haywire or turned against him (except when Timmy corrupted him with a video game).
411* ADayInTheLimelight: Goddard is by all means a main character, but the only episode that gives him the focus is "Best in Show", one of the last ever aired.
412* DoAnythingRobot: He does eleven million and four things! Except clean up after himself.
413* EatingMachine: There's several occasions where he also eats human foods like ice cream.
414* HeroicDog: Goddard is a good boy. He is lovable, constantly loyal to Jimmy, playful, kind, and just downright adorable.
415* JawDrop: He has this moment after seeing Jimmy dressed up for his date with Cindy. Being a robot, his jaw literally dropped.
416* MoralityPet: To Jimmy. Both figuratively and literally. While, at his worst, Jimmy will treat his friends like lab rats and his family as an afterthought, Goddard always brings out the best in him. He also acts as Jimmy's conscience, and always suggests doing the right thing when Jimmy asks him for options. He's also how Timmy was able to relate to Jimmy on care for (what Jimmy believes to be) artificially intelligent beings.
417* NonHumanSidekick: To Jimmy. A double example, being both a robot and a dog.
418* OneWordVocabulary: "Bark!" and no that's not an onomatopoeia, Goddard actually says "bark" as it's spelled out.
419* RobotBuddy: Jimmy's mechanical canine and best friend.
420* RobotDog: A robotic dog invented by Jimmy himself.
421* SelfDestructMechanism: His "plays dead" command is this. Goddard can reassemble himself despite his core combustion. This ability is vital to defeat Eustace's [[PowerCopying Robo Adaptoy]].
422* TheSpeechless: Except in the movie, where his options for Jimmy are read in a robotic voice.
423* TeamPet: A robot dog, who happens to be the gang's mascot.
424* UndyingLoyalty: He loves and is entirely loyal to his owner and creator, Jimmy. In "Krunch Time", he pulls Jimmy out of a crisis when the whole town (which includes Jimmy's own parents and friends) attempts to enslave him when he creates a candy so addictive they can't stop eating it.

427[[folder:Hugh Neutron]]
428[[quoteright:170:https://static.tvtropes.org/pmwiki/pub/images/hugh_neutron2_0.png]]
429->'''Voiced by:''' Mark [=DeCarlo=]
430
431-->'''Real name:''' Hubert Beaumont Neutron
432
433Jimmy's father, who averts the [[StandardFiftiesFather "Father Knows Best"]] ideal. Nevertheless, he's a chipper, upbeat family man who always has time to dispense words of wisdom for Jimmy, even if most of the time those words are better left ignored. He also has an obsession with ducks.
434----
435* AdultsAreUseless: Hugh is probably one of the biggest idiots in Retroville. In fact, he messes with Jimmy's inventions all the time.
436* BreakoutCharacter: Hugh was announced as DownloadableContent for ''VideoGame/NickelodeonAllStarBrawl'' before Jimmy himself, likely as a result of his then-recent boost in popularity.
437* BumblingDad: Boy, is he ever. Many times, Hugh would screw up one of Jimmy's inventions because of his moronitude and him being the typical, dim-witted bumbling father.
438* ChaoticStupid: Sometimes, such as abusing Jimmy's rewind remote for his own personal amusement, arousing the anger of the townspeople affected by his antics.
439* {{Cloudcuckoolander}}: Quite possibly the largest one in the series due to how much he's shown to be the weirdest person in Retroville, mainly because of his striking confidence.
440* TheDitz: [[DumbIsGood He's a nice moron]] at the very least.
441* EmptyNest: In "Jimmy Goes to College", he misses Jimmy so much he buys fleas which he all names Jimmy (or variations thereof) to fill the void Jimmy left behind.
442* {{Flanderization}}: While he was a bit eccentric in the original movie, the show made him a straight-up {{cloudcuckoolander}}.
443* FoolishHusbandResponsibleWife: He's the Foolish Husband to Judy's Responsible Wife. He's a goofball who has a strange obsession with ducks and often tells nonsensical pieces of advice. He's also messed up Jimmy's inventions on several occasions.
444* {{Gasshole}}: Even without drinking the Burping Soda, Hugh has burped more than anyone else in the series, including Carl.
445* GeniusDitz: While he doesn't have his son and wife's scientific and technical intelligence, Hugh actually has an insane memory when it comes to his passions like ducks and pies. He was even able to answer an obscure trivia question involving a space soap opera he binge-watched by spitting out the plot without even stuttering or pausing as if he had a mind-map with it all right in front of him. It is also important to note that Jimmy actually gets his intelligence from ''his'' side of the family, not his mother's.
446* GoodParents: Despite his bumbling nature, he's shown to genuinely love and care for his son and is completely supportive of his interests. He's also the one who helps Eustace Strych's father find the will to assert himself when his son misbehaves.
447* HappilyMarried: To Judy. In many of their scenes together they're usually shown being lovingly playful with each other and rarely fighting.
448* InSpiteOfANail: In the AlternateUniverse where he invested in [=McSpanky's=], he still married Judy (despite the fact that he's wealthy, and can have any wife he wanted).
449* JerkassBall: Twice as a result of Jimmy's inventions.
450** The first is when Jimmy altered the past so that his dad would invest his only money ($50) into the then non-popular restaurant [=McSpanky's=], to make his parents rich and allow him to get an expensive set of encyclopedias that he wants. Unfortunately, along with Judy, he becomes a snobby rich man with no interest in his son, forgetting his name and offering him some money to leave. He even refuses to help pay for a lifesaving operation for his father merely because he does not want to lose any money.
451** The second is when Jimmy uses a machine to turn him cool (and prevent him from embarrassing him at the Fathers Day performances at school). He becomes super popular with the town, but never wants to spend time with Jimmy or Judy anymore and plans to leave them to go on a World Tour as a pop star. He even initially ''refuses to save his son's life'' before his parental instincts finally kick in and revert him back to normal.
452** The third is when he and Carl's dad engages in a feud joined by their wives, he's more unreasonable and [[AbusiveParent crueler towards Jimmy in order to forbid him being friends with Carl]] then usually when his feuding with his neighbor clouded his better judgment with him going so far of degrading into an AbusiveParent and a FantasyForbiddingFather by [[DisproportionateRetribution banning Jimmy from inventing anything because so he could make the feud last]].
453* JumpOffABridgeRebuttal: Twisted.
454-->'''Jimmy:''' But Dad! All my friends are going!
455-->'''Hugh:''' I know, Son, but [[IceCreamKoan if all your friends were named Cliff, would you jump off them?]]
456* {{Leitmotif}}: He has his own character theme in the series that's usually played during moments when he wants to bond with his son.
457* ManChild: Probably the least intelligent person in Retroville, rivaling Carl and Sheen (who funnily enough, are fans of him). The guy's obsessed with ducks and pies, comes up with childish theories, and acts as if he's a ten-year-old. The only person who could rival his childishness is probably [[WesternAnimation/TheFairlyOddParents Timmy Turner's dad]].
458* {{Metaphorgotten}}: This along with his acts of making IceCreamKoan sayings or his [[SimplemindedWisdom unsophisticated knowledge]] to his sayings, some of his analogies can make little sense.
459* NeverMyFault: He gives this treatment to Judy when he sends the town back in time using Jimmy's Wormhole Generator. She does call him out on this.
460* NiceGuy: Despite being a BumblingDad, he is good-natured and a [[PapaWolf caring father]].
461* NiceJobBreakingItHero: Sometimes he causes the episode's problem.
462* ObliquelyObfuscatedOccupation: Eventually averted when we learn he's a car salesman.
463* PapaWolf: He's got his [[SugarWiki/MomentOFAwesome awesome moments]] in the TV series, from fighting mutant crabgrass to trying to scare off a bear with a torch. [[CrouchingMoronHiddenBadass Hugh may be an idiot]], but you [[BerserkButton do not threaten his son]].
464* SimpletonVoice: Although he doesn't completely have this dialect, his cadences would still have these in Hugh's mildly goofy voice to match his bumbling nature.
465* SimplemindedWisdom: Usually PlayedForLaughs when Hugh would give advice to Jimmy in such a hilarious manner because of [[IceCreamKoan how unimportant it usually is]] and how Hugh would hilariously believe that his own advice helps at all, being the bumbling person that he is.
466* SmartPeopleWearGlasses: Inverted. He's the least intelligent member of his family and the only one to wear glasses.
467* TrademarkFavoriteFood: Pie
468* TookALevelInDumbass: In the movie, he had his dumb moments and wasn't the sharpest tool in the shed, but he mostly resembled a very normal well-meaning father. In the show, he's the quirky ditz we know and love.
469* VerbalTic: He has a tendency to say "dehh" before he begins his sentences.
470* VocalEvolution: His voice originally sounded deeper in the movie before it became goofy and high pitched in the cartoon.

473[[folder:Judy Neutron]]
474[[quoteright:159:https://static.tvtropes.org/pmwiki/pub/images/judy_neutron2.png]]
475->'''Voiced by:''' Megan Cavanagh
476
477Jimmy's mother. She's happy to cook and clean and run the household, but does want some appreciation for all she does. After all, without her, Jimmy and Hugh's lives fall to pieces.
478----
479* FiftiesHair: Lampshaded in "Maternatron Knows Best".
480* ActionMom: She's incredibly athletic, coordinated, intelligent, and she keeps a plasma rifle in her utility closet. (For those tough ground-in stains!)
481* AdaptationalBadass: While she was certainly the more competent parent in the movie, the show substantially expanded her repertoire into an ActionMom.
482* AffectionateNickname: Hugh calls her "Sugarbooger".
483* ADayInTheLimelight: In "Maternatron Knows Best".
484* DeadpanSnarker:
485-->'''Judy:''' Hugh, are you aware that most of the things you say don't make any sense?
486-->'''Hugh:''' I know honey. I know.
487* DitzyGenius: Not ditz per se (she's certainly [[WomenAreWiser the intelligent one]] in her marriage with Hugh and more rational than he is) but she has her moments of ditziness. There are also numerous moments where she demonstrates it's definitely from her side of the gene pool that Jimmy gained his intellect.
488* EstablishingCharacterMoment: In the movie, while she first appears to a standard {{Housewife}}, she's almost immediately implied to have HiddenDepths when she begins discussing Hugh's car transmission.
489* FoolishHusbandResponsibleWife: She's the Responsible Wife to Hugh's Foolish Husband. She's presumed to be where Jimmy got his intellect and tends to be more focused on doing chores. Unlike Hugh, she seems to know how to work Jimmy's inventions.
490* FullNameUltimatum: "James Isaac Neutron!"
491* GoodParents: A loving and nurturing mother towards her son Jimmy.
492* HappilyMarried: To Hugh. In many of their scenes together they're usually shown being lovingly playful with each other and rarely fighting.
493* HypocriticalHumor: She says the identical-looking robot mom has a "hideous 1950s hairdo".
494* MamaBear: '''"Get away from my family, you ugly bucket of bolts!"'''
495* MundaneUtility: Uses a de-molecular cannon beam to clean difficult stains.
496* NiceGirl: For the most part, she's a loving mother and wife to her family.
497* OnlySaneWoman: Along with Libby. She's generally CloserToEarth than Hugh and Jimmy, and takes their quirks in stride... most of the time.
498* StacysMom: Carl has a crush on her.
499%% * TookALevelInJerkass: In Season 3, she's more hostile towards Jimmy.
500* WomenAreWiser: Compared to her bumbling husband.

503!Supporting Characters
504[[folder:Bolbi Stroganovsky]]
505[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/bolbi.png]]
506->'''Voiced by:''' Creator/PhilLaMarr
507
508A foreign exchange student from the country of Backhairistan, he's a happy-go-lucky, friendly, well-meaning kid who's always there when his friends need him.
509----
510* BreakoutCharacter: Originally introduced as a one-time character but has quickly become a fan favorite. To a point where he seems to be close to another major character.
511* BunnyEarsLawyer: As silly and strange as he is, he's an excellent actor.
512* ButtMonkey: In "El Magnifico" he pays a slapstick-heavy price so that Mr. Estevez can pull of his superhero hoax in front of Sheen. Not that anyone asked him to.
513* {{Cloudcuckoolander}}: He makes ''Sheen'' look sane by comparison.
514* DanceSensation: The "Slap Dance" from his homeland. "Slap slap slap! Clap clap clap! Slap slap slap! Clap clap clap!"
515* TheDitz: Though he seems like just a goofy foreigner at first.
516* FunnyForeigner: Kind of like [[Series/That70sShow Fez]] meets [[WesternAnimation/EdEddNEddy Rolf]]. The difference is that Bolbi's country is actually named ([[PunnyName Backhairistan]]).
517* HiddenDepths: He's a very good actor and had Macbeths' ''Life's But a Walking Shadow'' monologue committed to memory when he auditioned for the part: Jimmy, Betty, and Nick were left speechless, and Ms. Fowl was reduced to tears.
518* LoonWithAHeartOfGold: As crazy as he is, he's a good guy who likes to help his friends.
519* {{Ruritania}}: His homeland of Backhairistan.
520* StrongFamilyResemblance: His sister is just a slightly shorter version of him in blonde braids and make-up.
521* ThrowTheDogABone: In "Jimmy for President" where he becomes class president after everyone else is disqualified and "Out Darn Spotlight" where he gets the role of villain in the play and does such a good job that Principal Willoughby slates him for a spot in his next production.
522* TrademarkFavoriteFood: Kebabs. They appear to be standard cuisine in his country.
523* TookALevelInBadass: In "Win, Lose and Kaboom", he manages to help defeat Meldar's robots.
524* VocalEvolution: Had a slightly deeper voice and heavier accent in his first appearance.

527[[folder:Betty Quinlan]]
528[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/betty_quinlan.PNG]]
529->'''Voiced by:''' Creator/KathSoucie
530
531The girl of Jimmy's dreams, and sometimes the motivation for hi-jinks in his efforts to impress her. Cindy doesn't care for her... for ''some'' reason.
532----
533* BettyAndVeronica: Quite literally the sweet-natured Betty to Cindy's Veronica. [[{{Irony}} Ironically]], Betty looks like Veronica and Cindy looks like Betty.
534* BewareTheNiceOnes: Betty is as sweet as a jellybean, but she has her limits (especially when Cindy's jealousy issues are concerned).
535* ADayInTheLimelight: In "Out Darn Spotlight" and "Vanishing Act".
536* NiceGirl: One of the nicest characters, and among the only ones to consistently respect Jimmy.
537* ObfuscatingStupidity: She often plays off that she's either oblivious to Jimmy's crush on her or mildly reciprocates it, but "Vanishing Act" reveals that she's fully aware of Cindy's crush on him and supports her, viewing Jimmy as merely a friend.
538* TheRival: Unintentionally to Cindy. Had the series continued, there would have been an episode that focused on them. In said episode, Cindy and Betty would've finally opened up to each other and the two would've become friends.
539* SatelliteLoveInterest: Sort of. She's ''not'' oblivious to Jimmy's crush on her or Cindy's crush on Jimmy for that matter. It is also implied that while she might be flattered by Jimmy's affections, she knows he belongs with Cindy and is fully supportive of it.
540* ShipperOnDeck: While she's flattered by Jimmy's crush on her and has shown signs of potentially returning it, she recognizes that he'd be a better match for Cindy and even admits as such in "Vanishing Act".
541-->'''Betty:''' Just relax and keep out of my face. He's all yours.
542[[/folder]]
543
544[[folder:Ms. Fowl]]
545[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ms_fowl.jpg]]
546->'''Voiced by:''' Creator/AndreaMartin
547
548The cast's homeroom teacher.
549----
550* AnimalMotifs: Birds. Not just her name, but her appearance and mannerisms (long pointy nose, motioning her arms like wings, squawking, etc.).
551** In "I Dream of Jimmy", in Carl's dream, her desk is replaced by a giant bird nest and she lays eggs.
552* BunnyEarsLawyer: As odd as she is, she has proven many times to be a ReasonableAuthorityFigure.
553* {{Cloudcuckoolander}}: Occasionally teaches subjects that really aren't pertinent to an elementary school education ("And that's why cowboys are bow-legged," anyone?).
554** When all the kids in her class got sick and skipped school, she was so desperate to teach that she started lecturing the empty room and would then sit at the student's desks pretending to be answering her own questions.
555* DeathGlare: Unlike the other staff members at the school, she doesn't require a weapon to take down the unruly substitute teacher parents in "How To Sink A Sub". She uses her "skunk eye", which immediately intimidates people into backing down.
556* DubNameChange: She is named "Señorita Ave" (Ms. Bird) in the Latin American dub.
557* EveryoneHasStandards: In a FreezeFrameBonus in "My Big Fat Spy Wedding", at Beautiful Gorgeous and Jet Fusion's wedding, she's horrified to see a brainwashed Jet attack and strangle [[TeachersUnfavoriteStudent Sheen]] when Sheen says the trigger phrase.
558* GagNose: Resembling a beak, taking her whole bird motif much further.
559* HiddenDepths: Ms. Fowl isn't just any ordinary teacher.
560** "Foul Bull" -- She was once a cowgirl and uses her experience to ultimately save the day.
561** "Lady Sings the News" -- Principal Willoughby implies that Miss Fowl might be a trans woman.
562** In the Halloween episode she showed vast knowledge on how to defeat werewolves. As to how she claims she was once married to a werewolf.
563* JerkassToOne: While she's normally a fair and reasonable teacher to the rest of her students, she appears to have [[TeachersUnfavoriteStudent a particular enmity towards Sheen]]. Though considering that it's [[{{CloudCuckooLander}} Sheen]], [[JustifiedTrope you can imagine that there would be some valid reasons for why she considers him her least favorite student]].
564-->'''Ms. Fowl:''' I miss them all so much. ''(cries while inside her empty classroom)'' '''Except Sheen!'''
565* KavorkaMan: A female example. She attracted Thomas Edison, went dancing with President Hoover, flirts with Sam and was once married to a werewolf. All this despite being an old woman who looks like a chicken and has similar mannerisms.
566* LastNameBasis: Being a teacher, everyone just calls her Ms. Fowl but in "Substitute Creature" General Ernest Abercrombie states her name is "Winifred".
567* MeaningfulName: Fowl is another term for bird, in which fits her AnimalMotifs. Her Latin American name, "Señorita Ave", is more literal. (It means Ms. Bird.)
568* NoodleIncident: She was once married to a werewolf. She refers to it as "a story for another day". She also apparently served a prison sentence after a "grading and driving" incident, though she rather quickly asserts to Libby that the charges were never proven.
569* ReasonableAuthorityFigure: Despite her eccentricities, she's one of the most sensible adults at the school, ''especially'' compared to the more-incompetent Principal Willoughby.
570* SternTeacher: She has her moments.
571* VagueAge: Okay, she's old. But ''how'' old is she?
572** In one episode, she implies that 58 is ''young'' for her.
573** In "Make Room for Daddy-O", she mentions that it is the 82nd annual Father's Day Follies and states that she still remembers the first one like it was yesterday.
574** She's apparently old enough to have taught General Ernest Abercrombie and Dr. Finbarr Calamitous when they were children, the latter of whom is clearly an elderly man.
575** In "How to Sink a Sub", she states she has been teaching for 74 years, which (assuming she started teaching at 18) would make at least 92.
576** Lampshaded in "Attack of the Twonkies".
577-->'''Sheen:''' She is getting on in years, but I'm sure she's not a thousand.
578* VerbalTic: Tends to end sentences with a squawk-like noise.

582[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/principal_willoughby.jpg]]
583->'''Voiced by:''' Creator/RobPaulsen
584
585As the title suggests, the principal of Lindbergh Elementary.
586----
587* TheDitz: Can be rather gullible at times; such as when he bought Sheen's claim of going to the school's "[[BlatantLies Tanning Salon]]", hook, line, and sinker. Though it didn't take long for him to realize he'd been duped.
588-->'''Willoughby:''' Wait a minute! We don't have a tanning salon!
589* {{Keet}}: For a school principal, he is actually rather jovial and eccentric.
590* LargeHam: Falls into this territory every now and then.
591* LastNameBasis: Always referred to by his title, though the door to his office reveals his first name: William.
592* PuttingThePalInPrincipal: While he's not very good at his job, he's still a friendly and likeable guy who generally gets on well with the students.

596[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/nick_jimmy_neutron.png]]
597->'''Voiced by:''' Creator/CandiMilo
598
599Another one of Jimmy's friends, who is the cool guy that everybody loves at school, especially the girls.
600----
601* AdaptationalNiceGuy: He's much nicer and fleshed out than he was in the movie.
602* AdaptationalWimp: In the movie, Jimmy takes the backseat as Nick leads the charge against the Yolkians, and the class BadButt even manages to take out a couple of Yolkian guards by hijacking one of their spears... only to lose momentum upon seeing the giant alien-chicken, at which point he becomes completely useless and Jimmy has to lead the charge himself. Nick's later PaperTiger characterization suggests he would balk at even taking on the guards, if he had to do it again.
603* AllGirlsWantBadBoys: Which is why all the girls at his school dig him.
604* AmbiguouslyBrown: Nick appears to be Latino or Italian despite his English surname. The creators state that he is Brazilian.
605* AttentionWhore: He'll do anything for love and attention.
606* BadButt: Before his later characterization took hold.
607* BigBrotherMentor: Nick's like a big brother to Jimmy and often gives him advice to help him out when he's in a jam (even though Jimmy ends up in trouble because of it).
608* BigManOnCampus: The coolest guy in Jimmy's class.
609* BookDumb: He never got a 95 in his life.
610* BreakTheCutie: In "The League of Villains", it is implied he now hates himself.
611* TheChewToy: All of his appearances in Season 3 consist of him breaking his leg while skateboarding. Jimmy lampshades this during one of his news segments in "Lady Sings the News".
612* TheCharmer: Thanks to his AllGirlsWantBadBoys charm.
613* ChickMagnet: All the girls find him attractive.
614* DeadpanSnarker
615-->'''Sheen:''' Libby's right. We can't give up hope. We need to ask ourselves what Ultra Lord would do.
616-->'''Nick:''' That's actually a good question, Sheen. Maybe he'll just sit on the shelf because he's a doll!
617-->'''Sheen:''' He's not a doll! He's an action figure!
618* DemotedToExtra: Nick used to be an important character, but in the last two seasons, he barely shows up at all except to break his leg skateboarding. Had the series continued, Nick would've rejoined the main cast and continued to develop his relationships with Jimmy and the gang.
619* EvenBadMenLoveTheirMamas: Nick is shown to be a bit of a mama's boy.
620* {{Flanderization}}: Nick actually did earn his {{Badbutt}} credentials in TheMovie, successfully stealing a Yolkian laser spear from a guard and then putting both the guard and another nearby through a CurbStompBattle, until he lost his nerve partway through the Yolkian {{Kaiju}} hatching. In the show, he mostly became known for the traits of [[AdaptationalWimp high-pitched screaming and injuring himself]].
621* GratuitousGerman: He sang a lullaby in German to his twonkie, and knowing how twonkies respond to song, it's expected what happened to him.
622* HiddenDepths:
623** He only acts like a tough guy because he's insecure and afraid.
624** His operatic German lullaby for his twonkie is carried out in secret.
625** He's actually a very talented actor, as demonstrated in "Out Darn Spotlight" when he nails his audition for the SchoolPlay and quickly nabs the lead role.
626* JerkWithAHeartOfGold: Nick may be cynical, egotistical, and snarky, but he's also one of Jimmy's best friends and he's actually a really good person.
627* MeaningfulName: His last name is a reference to James Dean who is best known for playing similar "bad boy" roles.
628* MommasBoy: He's seen being comforted by his mother during the flight home in TheMovie. [[DisappearedDad No dad is present.]]
629* NiceMeanAndInbetween: He's the Nice to Cindy's Mean and Libby's In-Between. He's the coolest kid in school who's usually nice and easygoing, though he's not without his BewareTheNiceOnes moments.
630* NobleMaleRoguishMale: The roguish {{Badbutt}} to Sheen's [[TheCape Ultra Lord]]-fanboy noble in the movie.
631* OralFixation: In the movie, he was often seen with a lollipop in his mouth. Probably intended to be a G-Rated [[SmokingIsCool cigarette]].
632* PaperTiger: He's the ultimate cool dude, the girls all dig him, and he's supposed to be tough. In the movie, his part of the plan is to take care of the BigBad while the others rescue their parents. One look at his competition, though, and he goes screaming like a little girl.
633* PrettyBoy: Which is why all the girls love him.
634* RedOniBlueOni: The blue to Sheen's red.
635* SavvyGuyEnergeticGirl: The savvy guy to Brittany's energetic girl.
636* ScreamsLikeALittleGirl: Whenever something frightens him, especially once he first saw Poultra's eyes.
637* SensitiveGuyAndManlyMan: The manly man to Jimmy's sensitive guy.
638* TroubledButCute: A supposed tough kid who is considered cool and is popular with girls.

645Cindy's other best friend, who is often seen hanging out with her and Libby as a third member of Cindy's friend circle.

647* AgeInappropriateDress: The elementary school sure has a [[NoDressCode lousy dress code]] for letting her wear shirts that show off her belly button.
648* AscendedExtra: Would've become one in Season 4.
649* CloudCuckooLander: She's a comic foil to the otherwise brainy Cindy and Libby.

661* NoCelebritiesWereHarmed: [[Music/BritneySpears Blonde, hair, valley girl accent, midriff outfits. Sound familiar?]]
662* SavvyGuyEnergeticGirl: The energetic girl to Nick's savvy guy.

682Owner of the local hangout joint, The Candy Bar.
683----
684* BullyingADragon: Does so in the superhero episode the N-Men. Jimmy is a [[ComicBook/TheIncredibleHulk rampaging orange monster]] but upon seeing his parents, he starts calming down. Until Sam [[TooDumbToLive decides to throw fruit]] in Hulk/Jimmy's face. Needless to say, the mutated Jimmy doesn't take too kindly to it. This also came up in the HalloweenEpisode, though he had an angry mob to back him up.
685* DeadpanSnarker: One particular instant is in "Krunch Time", when he sarcastically remarks the suspense is killing him when Carl is unable to decide what kind of candy he wants.
686* {{Jerkass}}: N-Men episode again. [[JerkassHasAPoint He was right that something should have been done to try to help the kids control their newfound powers.]] However, calling the military up to ''imprison'' them and then telling the kid's parents they were just ''freaks'' was beyond the pale.
687* JerkWithAHeartOfGold: ''Gold'' might be stretching it, but he does have softer side for Ms. Fowl.
688* ShipTease: Sometimes has these with Ms. Fowl.
689* UngratefulBastard: He even says that Jimmy still owes him $1.80 for the heavy seltzer, even after the N-Men thank him for his help.

703* DatingCatwoman: Briefly got engaged to Beautiful Gorgeous, until it was revealed as a plot to kill Jimmy and get him out of the way.
704* DistressedDude:
705** The plot of his debut episode is about Jimmy and his friends having to rescue him from Professor Calamitous.
706** In his second appearance, he's brainwashed by his bride-to-be to assassinate Jimmy in a ploy to get rid of her hated enemies.
707* JerkWithAHeartOfGold: A bit of a showoff and full of himself, but a good guy for the most part.

714->'''Voiced by:''' Creator/PatrickStewart (movie), S. Scott Bullock (TV series), Joe Whyte (video game)
715
716King of the Yolkians, and Jimmy's first archenemy. In the movie, after making contact with Jimmy's communication satellite, he abducts the adults of Retroville in order to sacrifice them to the Yokian god, Poultra. Ever since Jimmy thwarted this plan, he's been trying to get his revenge on the boy genius.
717----
718* AliensAreBastards: An evil monarch from the space.
719* ArchEnemy: To Jimmy.
720* BigBad: The biggest one of the series. He is the main antagonist in the movie and in two episodes. Not to mention the main antagonist in the series' pilot and most recurring villain besides Calamitous.
721* CardCarryingVillain: He proudly claims to be a villain.
722* TheChessmaster: In the final episode, he is behind a very well-crafted plan to kill Jimmy.
723* EstablishingCharacterMoment: His first scene in the movie has him eating his own pet alien and then having a crew member [[ThrownOutTheAirlock spaced]] for [[DisproportionateRetribution unceremoniously showing up in his throne room]], all within a minute.
724* EvenEvilHasStandards: PlayedForLaughs. In ''The League of Villains'', he disapproves of the Junkman's idea to eat Jimmy, considering it to be disgusting. He also calls Eustace's idea of [[HumanHeadOnTheWall mounting Jimmy's head on a wall]] "barbaric".
725* FauxAffablyEvil: Goobot is [[LaughablyEvil funny]], [[EvilIsHammy hammy and over-the-top]], especially when he is in a good mood. However, he is also an authoritative, tyrannical monarch.
726* GreaterScopeVillain: Of the PC Jimmy Neutron game.
727* HairTriggerTemper: He tends to explode with anger when things don't go his way.
728* {{Jerkass}}: He's arrogant, self-centered, deceiving and authoritative.
729* KickTheDog: He usually does this when he is being outright cruel.
730* LaughablyEvil: Between his [[EvilIsHammy over-the-top reactions]] and his comical quirks, Goobot is easily one of the funniest villains in the series.
731* LegionOfDoom: He created "The League of Villains" consisting of several villains from numerous episodes including some of the Rogue Galleries.
732* PlanetBaron: By all appearances, he's the absolute ruler of every bit of the Yokian's homeworld.
733* PsychopathicManchild: He usually rejoices in his evil deeds, like a cruel child.
734* RedEyesTakeWarning: He has red eyes and is evil.
735* {{Sadist}}: In "The Eggpire Strikes Back", he is more than excited with the mere idea of destroying Retroville.
736* StarterVillain: He was the first villain in the franchise ever since the pilot in fact. Ironically, he was also the FinalBoss in ''The League of Villains''.
737* StarterVillainStays: Makes a return in the series including the finale ''The League of Villains''.
738* SurroundedByIdiots: Ooblar is nowhere near as intelligent as he is and he only keeps him around because he's his brother. His followers can be like this to some degree, and for that, he punishes them by sucking them out of his spaceship.
739* TaughtByExperience: Goobot learned from past experiences that Goddard, Jimmy's inventions and friends were things that foiled his plans, so, in ''The League of Villains'', he assigns his comrades to cut down Jimmy's access to them before formally catching him in the series finale.
740* TrappedInThePast: What becomes his ultimate fate in the series finale.
741* UncertainDoom: Because both Professor Calamitous and Eustace Strych were seen in the second and third Jimmy/Timmy crossovers, it's unknown if he and the rest of the League of Villains made it back to the present or not.
742%%* VileVillainLaughableLackey: The Vile Villain to Ooblar's Laughable Lackey.

752* AffablyEvil: He's unfailingly polite even when he helps Goobot with his wicked whims.
753* TheDragon: To Goobot.
754* LaughablyEvil: Even ''more'' than his boss.
755* MinionWithAnFInEvil: Though he does come close to killing Goddard in the movie and mentions that he likes seeing people being [[ThrownOutTheAirlock spaced]].
756* PluckyComicRelief: Serves as a comic relief character whenever he is around.
757* PutOnABus: Goobot apparently traded him for sulfur butter prior to "League of Villains".
758* TooDumbToLive: He's not too bright and this annoyed Goobot so much that, originally, in the novelization, Goobot was supposed to kill him with the Doomstick.

768* CanonForeigner: He's made for the PC Jimmy Neutron game.
769* CreepyMonotone: His voice is full of this.

785
786The Yolkians' "god[[AmbiguousGender (ess)]]", a gigantic chicken monster.
787------
788* AmbiguousGender: In the film, he's referred to as male and a "god", but in "The Eggpire Strikes Back", she's referred to by female pronouns. This ''may'' be justified because the Poultra who appeared in "The Eggpire Strikes Back" wasn't the same one as the original, but the episode words it in a way that suggests that Poultra has ''always'' been female.
789* BackFromTheDead: Subverted - she wasn't killed in the movie, but apparently died in between the movie and the show [[spoiler:though Ooblar states she simply left for another civilization]]. In the TV special "The Eggpire Strikes Back", a duplicate of her is cloned, and Jimmy mentions it's not the same Poultra.
790* FeatheredFiend: A giant killer chicken.
791* GreaterScopeVillain: While King Goobot is the BigBad in both the original movie and the episodes that feature him, Poultra is said to be the "god" that the Yolkians look up to.
792* ShoutOut: Her second death is a shout-out to [[https://en.wikipedia.org/wiki/Wawel_Dragon the Wawel Dragon]], of all things.

798
799Jimmy's other arch-nemesis and the show's main antagonist. A mad scientist with an inability to complete things (though he eventually overcomes this habit). He's constantly hatching evil schemes, usually dragging Jimmy into things.
800----
801* AbsentMindedProfessor: Calamitous when introduced was never able to finish anything, even his own sentences. From his second appearance onwards, he can now talk in complete sentences thanks to self-help classes. However, this habit appears again in "The League of Villains".
802* AffablyEvil: Sure, he's got evil scheme after evil scheme, but he's still a pretty friendly guy. For example, when he suffers a PottyEmergency, he politely asks Sam if he can use the restroom at the Candy Bar, and even tries to order some food when he's told the restrooms are for paying customers only. He even asks Jimmy how his old teacher, Ms. Fowl, is doing.
803* ArchEnemy: Seems to have taken this role up from King Goobot, as he's one of Jimmy's most recurring enemies.
804* BewareTheSillyOnes: Even before he took self-help classes to help him finish things, he was still as threatening as he was forgetful in his first appearance. He eventually gets to a point where he nearly ''destroys and remakes an entire universe''.
805-->'''Jimmy:''' For a bumbling genius, he's pretty dangerous.
806* BigBad: Expect him to fall into this role a lot, especially during crossovers.
807* DitzyGenius: He's just as smart as Jimmy and capable of building powerful inventions, but incapable of finishing anything he starts.
808* DopeSlap: Often gets these from his daughter.
809* EvilCounterpart: To Jimmy, although he's much older, and unlike Jimmy he failed elementary school.
810* EvilOldFolks: An old man who wants to take over the world with his intellect.
811* FatalFlaw: His inability to finish anything repeatedly comes back to bite him. In his first appearance, he's forced to abandon his pursuit of Jimmy because he kept forgetting to put a bathroom in his robot suit.
812* FreudianExcuse: Calamitous was a brilliant student, but he was unable to finish anything and failed Ms. Fowl's class, vowing to come back when the time comes. Through his lifetime, he was ridiculed for this tendency, driving him to seek vengeance.
813* InTheirOwnImage: After being fused with [[WesternAnimation/TheFairlyOddParents Jorgen von Strangle]], he intended to recreate all reality as he saw fit.
814* LoopholeAbuse: His mini-mecha is basically the only functional piece of equipment he has because he technically never put in a bathroom; everything else he has is usually missing a key component of some sort. It's implied that the whole bathroom bit is how he mentally got over not "completing" it.
815* MadScientist: He even has the look, the EvilLaugh, and a [[MadScientistsBeautifulDaughter beautiful daughter.]]
816* MiniMecha: A humanoid red model was his best work in his debut. Though it was still technically unfinished since he never put in a bathroom.
817* MissingStepsPlan: His big flaw is that he can never finish everything, and while self-help classes help him with his speech problem, this quirk is in full-force in his {{Evil Plan}}s.
818** In "[[Recap/TheAdventuresOfJimmyNeutronBoyGeniusS2E5OperationRescueJetFusion Operation: Rescue Jet Fusion]]", his plan is to use his laser to melt the snow off of Mt. Everest, flooding the world so that he can... do something.
819** In "The Great Egg Heist", he tricks Jimmy and his associates to steal a priceless jade egg so that he could power his doomsday device. What he'll ''do'' with the device he still hasn't figured out.
820* OmnicidalManiac:
821** In "[[Recap/TheAdventuresOfJimmyNeutronBoyGeniusS2E5OperationRescueJetFusion Operation: Rescue Jet Fusion]]", he tries to flood Earth to destroy it.
822** In "[[WesternAnimation/TheJimmyTimmyPowerHour The Jimmy Timmy Power Hour 2: When Nerds Collide!]]", he creates a bomb using Jorgen's magic that would have blown up the universe.
823** In ''VideoGame/NicktoonsUnite'', he and the other villains build a doomsday device powerful enough to destroy universes, with Retroville as the first test. Luckily, he forgot to install a backup supply, meaning he's stopped when the power is cut.
824* SpeechImpediment: His compulsive inability to finish anything also applies to sentences, usually fishing for the last word. By "Operation: Rescue Jet Fusion", he overcame this problem through a self-help course.
825* TakeOverTheCity: In his first appearance. Jimmy assumes he's just gonna {{take over the world}}, but he says he's going for something smaller.
826* UnroboticReveal: In his debut episode, Calamitous was shown piloting his mini-mecha, which he soon exits, revealing himself to be a human.
827* WouldHurtAChild: Considering the showdown he usually has with Jimmy, this trope suits him. In a crossover with WesternAnimation/TheFairlyOddParents, he outright tried to kill him using Jorgen's magic. Thankfully, fairy magic is not made to harm.

833
834Professor Calamitous' daughter. Her real name's Georgia Calamitous. Jimmy, Carl, and Sheen are easily seduced by her looks.
835----
836* AffablyEvil: Much like her dad. In her very first appearance, she chats amiably with Jimmy, Carl and Sheen and even serves them milkshakes before almost regretfully saying she'll have to kill them.
837* AnnoyingLaugh: Snorting variation in every full, uninterrupted EvilLaugh. Sheen even lampshades it.
838* BeleagueredAssistant: In ''Operation: Jet Fusion''. She often bemoans having to do Calamitous' dirty work and put up with his eccentricities.
839* BondVillainStupidity: She devised a death trap for Jimmy and Jet Fusion instead of killing them directly like the majority of Bond villains. Considering her debut is in an episode parodying spy films, it's to be expected.
840* CareerNotTaken: A RunningGag has her almost admitting what she really wanted to do (revealed in "My Big Fat Spy Wedding" being [[spoiler:putting aglets onto the ends of shoelaces]]), but her father Dr. Calamitous raised her to be a supervillain just like him.
841* CharacterizationMarchesOn: Her first appearance implies that she was only evil reluctantly, feeling obligated to engage in it out of loyalty to her father. This doesn't carry over to later episodes.
842* DarkActionGirl: She's a very skilled martial artist and nearly defeats Jet Fusion in hand-to-hand combat.
843* DeadpanSnarker: She often has something snarky to say.
844* DudeMagnet: How every guy in the show reacts towards her.
845* IKnowKarate: To be accurate, she knows 112 forms of martial arts. She proved her prowess by getting the upper hand on Jet Fusion.
846* ImpossibleHourglassFigure: Her waist is ''comically'' small, and her bust is much larger than any other character in the show
847* InterspeciesRomance: With the Junkman due to Jimmy's LovePotion.
848* MadScientistsBeautifulDaughter: Her name is half James Bond Reference, half beating this trope over your head.
849* MeaningfulName: She wasn't exactly very creative with the villain alias. Or subtle.
850* MindControlDevice: She made one to hypnotize Jet Fusion in the form of a box of candy. Also did this Jimmy with his HypnoRay.
851* MsFanservice: Understatement of the year.
852* OlderThanTheyLook: Jimmy guessed 22, which based on her amused face, isn't accurate. Still Beautiful seemed [[ProudBeauty quite flattered]] he'd mistakenly think that.
853* ProudBeauty: Her self given villain name says everything.
854* RunningGag: Every time she mentions she wanted to have a certain career other then villainy, she always gets interrupted or cut off. [[spoiler:It was to make [[WhatTheHeckIsAnAglet aglets]] for a living.]]
855* SensualSpandex: Usually seen wearing a form fitting black catsuit.
856* TheTease: Enjoys the effect her sex appeal has on men, often playing it up to toy with them. Perfectly demonstrated by [[PrecociousCrush Jimmy, Sheen and Carl's reactions]] to her during their first encounter, Gorgeous clearly getting a kick out of how flustered she makes them.
857* ThenLetMeBeEvil: Apparently she never wanted to be evil; just felt obligated to because her father was doing it. [[VillainousLineage Then comes "My Big Fat Spy Wedding"...]]
858* TrappedInThePast: Which becomes her fate at the end of the series.
859* UglyGuyHotWife: With Junkman.
860* TheUglyGuysHotDaughter: Her dad's very short and peculiar-looking at best, while she very much lives up to her name. Presumably, she got her looks from her mother.
861* UncertainDoom: Because both her father Professor Calamitous and Eustace Strych were seen in the second and third Jimmy/Timmy crossovers, it's unknown if Gorgeous and the rest of the League of Villains made it back to the present or not.

867
868A snobby rich kid who buys all of his gadgets from his dad. He's one of the members of the League of Villains created by Goobot.
869----
870* ArchEnemy: He sees Jimmy as one. Along with King Goobot and Calamitous, he's one of the most recurring villains in the show.
871* AxCrazy: He's very good at hiding it. He laughs maniacally in "King of Mars"; and in "The League of Villains", he expressed the desire to hang Jimmy's head on the wall, something that [[EvenEvilHasStandards even Goobot considered it "barbaric"]].
872* BadBoss: He uses his personal butler, Blix as an abuse dummy.
873* BritishTeeth: Unlike most examples of this trope, he doesn't have crooked or yellow teeth. He ''does'' however have large buck teeth that stick out. Jimmy even calls him "Captain Overbite" in his debut episode.
874* TheCharmer: The main reason why Cindy had a crush on him.
875* ComedicSociopath: Perhaps Eustace ''really'' qualifies as a true sociopath. Nevertheless, his butler, Blix is often used as an "abuse dummy" for his rage or to add to him being hilarious.
876* EvilBrit: Has a UsefulNotes/{{British Accent|s}} to go with his rich jerk persona.
877* EvilCounterpart:
878** To Jimmy. They both have a lot of high-tech gadgets, but while Jimmy is usually well-behaved and makes them himself, Eustace has his inventions bought and is a spoiled brat.
879** Unintentional, but his status as the cool guy and TheCharmer makes him an evil version of Nick Dean.
880* EvilIsPetty: He's a petty, sadistic jerk.
881* ExpospeakGag: He toasts Jimmy a flowery, grandiloquent way, knowing Jimmy wouldn't understand and assume he was being insulted. In reality, Eustace was complimenting him, just sarcastically.
882* FauxAffablyEvil: When he's in a good mood, Eustace is fairly polite and charming. Underneath his polite facade, however, he's unpleasantly malicious and petty.
883* HateSink: He is incredibly arrogant, vain, narcissistic, snobby, and while he is not as evil as most of the show's villains, he compensates by being an incredibly irritating SmugSnake without redeeming qualities. Just think of [[WesternAnimation/ThePowerPuffGirls Princess Morbucks]] as a male version.
884* {{Jerkass}}: He's cruel, obnoxious, and used Cindy's love to emotionally crush Jimmy and then, he forced Jimmy to watch Goddard die.
885* JerkWithAHeartOfJerk: He showered Jimmy's friends with gifts and a banquet, but it was all just to make Jimmy jealous.
886* KickTheDog: He does many in his first appearance:
887** First, he steals Jimmy's friends with gifts.
888** Second, he says mean things to Jimmy in front of his friends and Hugh.
889** Finally, he makes Jimmy bet Goddard in a battle against his robot cat and when he reveals his true colors, he throws Cindy to the ground and insults her.
890* LaughablyEvil: He may be an obnoxious asshole, but he can be hilarious at times.
891* LiteralAssKicking: In "Billion Dollar Boy", he angrily kicks his butler in the butt when he loses two competitions to Jimmy.
892* ManipulativeBastard: Both in "Billion Dollar Boy" and "King of Mars", he manipulated Cindy with his superficial charm.
893* PoliteVillainsRudeHeroes: When he is in a good mood, Eustace is polite, superficially charming, has stereotypical mannerisms of the highest social status, and speaks in a formal manner; while Jimmy, TheHero, is a blunt, rude boy with NoSocialSkills.
894* PragmaticVillainy: Forms an EnemyMine with Jimmy and his pals in "King of Mars" when [[SiliconBasedLife the Martians]] try to destroy it. Not because of any moral reasons, mind you, but because Earth is where he keeps all his stuff.
895* RichBastard: While his billionaire dad is a decent guy, Eustace himself is a selfish, ruthless jerk.
896* SissyVillain: During ''The League of Villains'', he possesses weirdly effeminate mannerisms.
897* TheSociopath: He's manipulative, uncaring, abusive, unapologetic, narcissistic, and overall cruel to everyone around him without even a shred of remorse. He even suggested mounting Jimmy's head on a pike.
898* SmugSnake: Probably one of the less threatening antagonists Jimmy has faced.
899* SoftSpokenSadist: When he is calm, he doesn't raise his voice.
900* SoreLoser: Whenever he loses a competition, he has Blix bend down while he kicks him in the rear repeatedly.
901* SpoiledBrat: His father has difficulty disciplining him until Hugh encourages him to do so. When his dad finally punishes him for his misbehavior, he just yells at him while crying when he's sent to his room.
902* TantrumThrowing: Done when he's kicking his butler.
903* TrappedInThePast: His fate in the series finale, though he was seen back in the present time in the third Jimmy/Timmy crossover.

945->'''Voiced by:''' Creator/DaranNorris (01) and Creator/TomKenny (02)
946
947A duo of nanobots created by Jimmy to operate several of his inventions. They almost immediately go haywire and become increasingly insane and fanatical as the series goes on.
948----
949* AIIsACrapshoot: They're designed to balance each other out, but they mostly seem to do the opposite. They're constantly bickering with each other, and when they do agree, it's to make extreme misinterpretations of Jimmy's demands.
950* BewareTheSillyOnes: Their personalities and bickering are mostly comical. However, these two are easily among the most dangerous antagonists in the series as their second appearance saw them literally seconds away from the extinction of the human race.
951* CuttingTheKnot: In their second appearance, this is how they resolve Jimmy's first attempt to beat them. Jimmy argues that humans are naturally flawed, and that such flaws are natural and a sign that humans are working perfectly. After some pondering, the nanobots file the conundrum and humanity as an extreme error. Since they're meant to delete extreme errors, they decide to delete everyone.
952* CyberCyclops: They were originally built with one eye in their debut appearance, but Jimmy later upgraded them with two eyes after that.
953* FatAndSkinny: 01 is shorter and rounder while 02 is tall and lanky.
954* KnightTemplar: They take their anti-bullying directive (and whatever other task Jimmy gives them) VERY seriously and well beyond the point of overkill.
955* LogicBomb: How they are typically defeated. Their first appearance Jimmy abused their directive to protect him from attackers by beating himself up in front of them. In their second appearance (after Jimmy's first attempt at this [[NiceJobBreakingItHero made things]] much, [[KillAllHumans MUCH worse]]) Jimmy overloaded them by forcing them to calculate the exact value of pi. In addition, when Jimmy repurposes them to proofread his artistic classwork, his attempts at poetry are so bad they also has this effect.
956* ObliviouslyEvil: To them, they're not doing anything wrong. They're simply carrying out Jimmy's orders to protect him/correct errors. And in Fundemonium, they're convinced that the townsfolk they are terrorizing are enjoying the mayhem they cause.
957-->'''01:''' It warms my dials to bring such joy to the world.\

964
965The host of the hit game show "Intergalactic Showdown" and [[BigBad the main villain]] of the TV movie "Win Lose and Kaboom".
966----
967* AliensAreBastards: He's an alien and an OmnicidalManiac.
968* BigBad: Of "Win Lose And Kaboom".
969* DeadpanSnarker: Quite a bit.
970-->''(after Sheen gets torched by an alien)'' Oh nice try Sparky, but next time wait till [[SuddenlyShouting I START THE GAME.]]
971* FauxAffablyEvil: Rarely drops his cheery, hammy attitude even while threatening to ''blow up people's planets''. At the end, he finally stops and decides to [[LetsGetDangerous get serious]].
972* ForTheEvulz: He threatens to destroy other people's planets. Why? To get better ratings.
973* {{Hypocrite}}: Insists during the race that there's no cheating allowed, but permits the Brains to put Jimmy and the gang into a LotusEaterMachine. Later he panics at the idea of his quadrant being blown up despite the fact that his entire show is about blowing up completely innocent planets simply because their species [[DisproportionateRetribution lost a game]].
974* LargeHam: He's a GameShow host. It comes with the territory.
975* LaserGuidedKarma: He is forced to hand over his show to the Brain aliens and advertise an exercise machine that implements ElectricTorture, which he says is extremely painful.
976* LaughablyEvil: Despite being an evil alien, he's very funny and over-the-top.
977* MundaneUtility: He has a pair of "matrix generators" with a seemingly limitless ability to manipulate time and space. How does he use them? To create a high-stakes game show, of course.
978* OmnicidalManiac: "Winner gets a brand new car! Loser gets their home planet ''destroyed''!"
979* RealityWarper: Thanks to the matrix generators in his cufflinks.
980* SmugSnake: He's definitely dangerous, but his pride makes him rather short-sighted.
981* SufficientlyAdvancedAlien: His seemingly supernatural hold over reality, time and space is powered by a pair of matrix generators hidden in his cufflinks.
982* TimeAbyss: Implied, as April states that his show has existed for eons.
983* VileVillainSaccharineShow: He is more than capable of destroying planets and transmitting matter and energy, courtesy of his matrix generators.
984* VillainousBreakdown: Loses it when he discovers that his show is about to be destroyed.

990->'''Voiced by:''' Creator/MauriceLaMarche (Zix), Creator/JeffBennett (Travoltron), Creator/KevinMichaelRichardson (Tee)
991
992A trio of space bandits Jimmy and friends met when they tried to dig for Asterubies. Later, they tried to sell shrunken Retroville townspeople as toys and joined the League of Villains.
993----
994* AbortedArc: After taking the melted [=McSpanky's=] building as their vessel, Zix states that they'll go hunt down the "captain" Skeet. But this never went anywhere unless they found him offscreen.
995* ActorAllusion: [[WesternAnimation/TheProudFamily Tee isn't Kevin Michael Richardson's first role]] being a Mr. T Expy.
996* ArmorPiercingQuestion: After having a HeelFaceTurn of his own, Tee uses one of these on Zix and Travoltron to make them undergo one.
997-->'''Tee:''' Well why ya gotta be villains?!\
998''(Both Zix and Travoltron stammer trying to find an answer and failing)''
999* ButtMonkey: Tee was treated as this by his fellows in the League of Villains. This and Sheen's willingness to hear his story out were what triggered his HeelFaceTurn.
1000* FingerGun: All three of them use this motion when shooting some kind of gooey substance used in sealing Jimmy's lab.
1001* GoodFeelsGood: What Zix and Travoltron thought after helping Jimmy and friends, showing that their HeelFaceTurn would be permanent.
1002* HeelFaceTurn: Tee during Jimmy and Sheen's imprisonment. Zix and Travoltron followed during the cast's time in the Cretaceous Era.
1003* ManHug: Tee really likes to give this. [[CuddleBug Well, a bit too much.]] Travoltron too, to a lesser extent.
1004* MistakenForGay: While his orientation isn't known, Zix & Travoltron have this reaction to Tee wanting to open up a dress shop as they glance at one another awkwardly & slowly back away from him.
1005* MistreatmentInducedBetrayal: Tee turns against the League of Villains because most of its other members continuously demean and disrespect him.
1006* NiceMeanAndInbetween: Travoltron, Tee, and Zix, respectively. Travoltron is the Nice, who like Sheen, is the wackiest of the trio and is often smiling. Tee is the Mean, being the most confrontational and aggressive of the group. Zix is the In-Between who is the often level-headed leader that tries to keep the trio together, while at the same time, trying to accomplish their evil goal at the time. Once they all pull a HeelFaceTurn at the end of the series, they all become nice.
1007* NoCelebritiesWereHarmed:
1008** Tee is an alien who talks and acts like Creator/MrT.
1009** Travoltron was derived from and acts like Creator/JohnTravolta. Or at least his character in ''Film/SaturdayNightFever''.
1010** The third one, Zix, talks like Creator/JonLovitz. A bit more devious than Jon Lovitz though...
1011* RealMenHateAffection: In contrary to Tee and Travoltron, Zix hates the ManHug, but he will accept a handshake with his teammates.
1012* RealMenWearPink: Tee mentions in "The Incredible Shrinking Town" that he dreams of opening a dress shop.
1013* SpeaksFluentAnimal: Since their species is apparently reptilian, they can understand and speak lizards' language. They use this ability to distract a T-rex from eating Jimmy and his friends.
1014* ThinChinOfSin: All three of them have a distinctively pointed chin. When their faces are neutral, their jaws resemble bandanas, which is fitting for a trio of bandits.
1015* VerbalTic: Tee tends to have "Fool!" in most of his sentences.

1021->'''Voiced by:''' Creator/RobPaulsen
1022----
1023* BerserkButton: '''''MUSIC'''''. Particularly pleasant music as they consider awful singing to be lullabies for them. Although this seems to have stopped after their first appearance, though, as one can be seen during a big musical number at one point.
1024* TheCameo: They can be seen appearing in a brief time in several episodes, can even be seen several times in one episode.
1025* {{Expy}}: They're very reminiscent of the titular monsters from ''Film/{{Gremlins}}'' (starting out as harmless and cute creatures before morphing into dangerous monsters) as well as the Crites from ''Film/{{Critters}}'' (they're aliens and they often get around by rolling into balls).
1026* FishEyes: They have them.
1027* KillerRabbit: And how?
1028** VillainDecay: After their first appearance, Twonkies are treated as if they were normal rabbits.
1029* MonsterOfTheWeek: In ''Attack of the Twonkies''. They later became {{Recurring Extra}}s.
1030* OnlyOneFindsItFun: The twonkies respond positively to Sheen's HollywoodToneDeaf singing. Jimmy uses this to pacify the transformed twonkies and send them back to space.

1036
1037An alien. He runs a shady trash-collecting business.
1038----
1039* CatchPhrase: "You trash it, I cash it!"
1040* DirtyCoward: He breaks his promise to Jimmy, Carl, Sheen, Goddard and the Brobot's and leaves them on the ship to die.
1041* EvenBadMenLoveTheirMamas: Subverted. He sold his mother and took the best offer for her due to the fact that he "couldn't put a price on her".
1042* ExtraEyes: Has an additional set of eyes on the back of his head.
1043* FatBastard: He's a fat jerk who only cares about the profits that can be made from what he can sell.
1044* FauxAffablyEvil: Surprisingly laid back for a repulsive alien creature that runs a shady business, but at his core is positively ruthless.
1045* InterspeciesRomance: With Beautiful Gorgeous.
1046* LargeHam: A Charlie Adler speciality.
1047* MultiArmedAndDangerous: He has four arms and is really evil.
1048* PetTheDog: Subverted; He mentions that his alien dog, Roxie, is the only thing in the galaxy that ever showed him love, loyalty and affection...then offers to sell her for a ludicrously high price. He's also not pleased when she [[DefectingForLove falls in love with Goddard]] and calls her a traitor.
1049* TrappedInThePast: His fate in the series finale.
1050* UncertainDoom: Because both Professor Calamitous and Eustace Strych were seen in the second and third Jimmy/Timmy crossovers, it's unknown if he and the rest of the League of Villans made it back to the present or not.
1051* UnholyMatrimony: Parodied when Jimmy uses a love potion on him and Beautiful Gorgeous. Their hatred for each other promptly becomes love.

1056->'''Voiced by:''' Mark [=DeCarlo=]
1057
1058Jimmy's 17.5-month-old cousin. Despite his infantile appearance, he's actually very devious and a genius; capable of walking, speaking fluently, and devising a plan to kill all of the Neutron family members. He later joined Goobot's League of Villains.
1059----
1060* AlwaysSomeoneBetter: He's even smarter than Jimmy, even as a baby.
1061* AxCrazy: He is incredibly sadistic, murderous and violent.
1062* BeneathSuspicion: Jimmy was able to deduce that one member of his extended family was secretly a genius capable of sabotaging his invention. Unfortunately, he never suspected that the secret genius was a toddler, and Eddie only reveals himself when he gets the upper hand.
1063* BitchInSheepsClothing: His first appearance. Since his identity had been uncovered, he dropped the nice facade in subsequent appearances.
1064* BrainyBaby: A baby capable of reading, walking, talking and various things human adults can do, except changing his own diapers and controlling his excretion/digestive system.
1065* CasanovaWannabe: Tried flirting with Beautiful Gorgeous, with negative results.
1066* CharlieBrownBaldness: Has one visible gravity-defying strand of hair only. Justified, in that he's still a baby.
1067* CoolBike: His motorcycle can frickin' ''bring him to space''. Too bad it only appeared in the "bad guys assemble montage" at the beginning of the "League of Villains" episode.
1068* EnfantTerrible: Duh.
1069* EvilGenius: Who knows how a 17.5-month-old baby can outsmart Jimmy at first, and almost succeed in killing his family members using Jimmy's own things?
1070* EvilSoundsDeep: He has a really deep voice, a clear contrast to [[VocalDissonance his small appearance]].
1071* InTheBlood: In earlier seasons, it was implied that Jimmy gets his smarts from his mother, but Eddie's debut episode reveals that there's a recessive gene on Hugh's side that occasionally sires a super-genius. Jimmy's got it, and so does Eddie.
1072* LikesOlderWomen: He has a thing for Beautiful Gorgeous, who's at least 20 years his senior. Of course, being an infant means most women are older than him by default.
1073* OnlySaneMan: Putting aside his need to change diapers, he's mostly this with King Goobot.
1074* ReusedCharacterDesign: His model was reused from when Granny Neutron turned into a baby in "Granny Baby".
1075* RunningGag: He kept asking his fellow teammates to change his diaper with no success. The joke came in full circle when he took off his own 5-day-old diaper to chase a T-Rex away.
1076* StatingTheSimpleSolution: While other members of the League of Villains debated on how to kill Jimmy and Sheen using convoluted (or even silly) ways, he stepped up and said [[ThrownOutTheAirlock "Just blow him into deep space!"]] to which everyone agreed.
1077* TimeOut: Jimmy's Aunt Amanda gives him one at the end of the episode "Clash of The Cousins" after he attempted to fake his innocence and anger her.
1078* TrappedInThePast: His official defeat.
1079* UncertainDoom: Because both Professor Calamitous and Eustace Strych were seen in the second and third Jimmy/Timmy crossovers, it's unknown if he and the rest of the League of Villains made it back to the present or not.
1080* VocalDissonance: Despite being an infant, he has a pretty deep voice.
1081* WoundedGazelleGambit: In the episode "Clash of The Cousins". He was only able to keep up this facade for so long though before Aunt Amanda became furious at the fact that she had been defending his actions and soon forgives Jimmy while giving Baby Eddie a timeout.

1087
1088An alien who looks like an old lady. She attempted to hypnotize the world into a state of perpetual happiness with her TV Program "The Happy Show Show", but was foiled by Jimmy and Cindy. She later joins the League of Villains to take revenge on Jimmy.
1089----
1090* AmbiguouslyEvil: What she's up to is unambiguously creepy and sinister, but it's unclear if she herself had altruistic motives or had some hidden, evil purpose. In her second appearance, she's clearly evil, motivated solely by revenge on Jimmy.
1091* AffablyEvil: One of the best examples in the show. She has a friendly, pleasant and sugary-sweet demeanor, despite being an evil alien being that wants to hypnotize all of humanity.
1092* BlackEyesOfEvil: Can make her eyes look like this at will.
1093* GettingSmiliesPaintedOnYourSoul: Her show does this, hypnotizing anyone who watches it through to the end into being constantly happy.
1094* GracefulLoser: Takes both of her defeats in stride. Fitting, considering her AffablyEvil status.
1095* GrannyClassic: Played around with. Grandma Taters ''is'' [[AffablyEvil genuinely as polite and sweet as she presents herself as being]], but she's also an evil alien invader.
1096* HumanAliens: Her entire species apparently looks like a bunch of identical old ladies. They also all have the same AffablyEvil demeanor.
1097* MassHypnosis: Her debut episode, she uses a TV series to hypnotize the whole world into becoming {{Stepford Smiler}}s.
1098* TeamMom: Surprisingly (or [[GrannyClassic maybe not so surprisingly]]), she acts rather motherly towards the other members of the League of Villains, including consoling Professor Calamitous when [[spoiler:Beautiful Gorgeous falls in love with the Junkman]]. Though she draws the line at changing Eddie's diaper.
1099* ToServeMan: She apparently likes to drink brain juice and in "League of Villains" she tells Baby Eddie that she could ''literally'' "eat him up" if she wanted to.
1100* TrappedInThePast: With the other villains.
1101* UncertainDoom: Because both Professor Calamitous and Eustace Strych were seen in the second and third Jimmy/Timmy crossovers, it's unknown if she and the rest of the League of Villains made it back to the present or not.
1102* WellIntentionedExtremist: Seems to see herself as one, at least, as she claims that she genuinely wanted to make everyone happy. Her way of going about it wasn't pleasant, though.

1109A very, ''very'' eccentric scientist stationed in the mysterious Bahama Quadrangle, where he's responsible for the disappearances there, turning people into "algae men".
1110----
1111* AffablyEvil: Fairly polite for a crazy lunatic.
1112* {{Cloudcuckoolander}}: He really puts the "mad" in "mad scientist". His affinity for tap dancing is just the first clue.
1113* LargeHam: He's VERY dramatic.
1114* LaughablyEvil: It's hard to take him seriously when he's dancing around and shouting every other scene.
1115* MadScientist: He kidnaps people and turns them into plant people to act as his personal servants.
