[[folder:XJ-9/Jenny Wakeman]]
-> ''"I want to have friends, and hang out like normal teenagers do! But who would want to hang out with a rusty hunk of metal like me?"''

->Voiced by: Creator/JaniceKawaye

The main protagonist and the "16-year-old robot" ([[RunningGag built 5 years ago]]) to which the title refers, a state-of-the-art sentient gynoid automaton created by Dr. Noreen Wakeman five years prior to the series, though she was designed as a 16-year-old girl. Though XJ-9 was designed to be Earth's protector, armed to the teeth with a wide range of weapons, devices, and transformations, she wants to live the life of a normal teenager and often makes this desire quite apparent to her friends and creator.
* ActionGirl: A ridiculously powerful crime-fighting robot.
* {{Adorkable}}: When she gets acquainted with the real world for the first time.
* TheAgeless: Since Jenny is a robot, she'll look like a teenager forever, though she does seem capable of maturing mentally. She even has a dream of hanging out with her classmates when they're in the retirement home and she looks no different than the present.
* AintTooProudToBeg: Typically to her mother when she don't get her way.
* AllOfTheOtherReindeer: No matter what she does, she will always somehow end back up as the school freak.
* {{Animesque}}: Her character design, just look at her!
* ArtificialFamilyMember: Even though Nora Wakeman created Jenny to protect the Earth, she was still treated like a daughter.
* BadassAdorable: A OneManArmy shaped like a cute robot girl.
* BalloonBelly: She has inflated more than once, despite being made of metal.
* BareYourMidriff: Jenny's design is meant to give this impression, with blue plates at her chest and waist mimicking a tank top and a miniskirt. A screw in the center mimics a belly button.
* BewareTheNiceOnes: Her temper is incredibly human, all things considered. Combine that with a HyperspaceArsenal, and you get literally-explosive anger.
* BigSisterInstinct: Jenny is rather protective of Tuck, and generally treats him like her was her little brother. His screaming even helped her when FightingFromTheInside.
* {{Bifauxnen}}: Some of her outfits, such as in "Grid Iron Glory", a select few in "Victim of Fashion" and her persona as Ruby Rocket in "Girl of Steal" make her an occasional example.
* BlueIsHeroic: Her body is white with blue paint on the parts that resemble hair and clothing.
* BlushStickers: When she blushes, she displays blue-colored ones.
* BornAsAnAdult: This issue is addressed in the episode "I Was a Preschool Drop-out" when XJ-9 is forced to attend preschool after the authorities find out she has only been active for five years. The later episode "Humiliation 101" had Nora reveal to Jenny's classmates that, while she came online with an adolescent body, she still had an infantile mind and was even strapped to a baby's highchair.
* BrattyTeenageDaughter: She sometimes acts like a disobedient teenage delinquent to Dr. Wakeman.
* ButtMonkey: She suffers misfortunes quite a bit, the worst offenders including "Ear No Evil" (where she is ceaselessly mocked for her goofy-looking ears) and "Killgore" (where the title antagonist keeps pestering her and she's unable to fight back without being seen as cruel by the people who adore Killgore).
* CatchPhrase: '''Crikey!'''
* CoolLoser: It's hinted that if the school weren't under the tyrannical reign of two {{Alpha Bitch}}es, Jenny wouldn't be a reject at all.
* CurtainsMatchTheWindow: Her hair and outfit colors match.
* CuteBruiser: Built like a teenage girl and a super robot that regularly pummels monsters into the crowd.
* {{Cute Machine|s}}: Just look at her, she's a total sweetie!
* DeadpanSnarker: Started developing into sardonic banter by season two.
* {{Demonization}}: {{Subverted}} InUniverse; Queen Vexus of Cluster Prime demonizes [=XJ9=], presenting her like an AlwaysChaoticEvil, [[BeautyEqualsGoodness horrible monster]] robot that wants to destroy her own kind in various propaganda videos showed to the robots. When [=XJ9=] accidentally goes to Cluster Prime, all the robots see her for the cute, normal, [[TheHero heroic robot who wants to help and protect others]]. [[spoiler: Even when someone recognizes her and the Robot police try to catch her, she is helped by her new friends. This leads to Queen Vexus’ downfall]]. There is also the fact that the propaganda doesn't bother showing her true appearance, allowing Jenny to remain HiddenInPlainSight.
* DentedIron: She may be tough but she has her limits. Many times she gets beaten up to the point where she can hardly fight.
* DestructiveSaviour: Often causes buildings to get destroyed she fights monsters.
* DitzyGenius: A highly advanced and intelligent combat android. But she's pretty clueless and naïve when it comes to mingling with non-robotic teens.
* DoAnythingRobot: Her arsenal is downright {{Hammerspace}}y.
* DoesNotKnowHerOwnStrength: Jenny has some initial problems fitting in due to this, but eventually gets used to her surroundings. At home, she seems to have either figured out how to lounge around without breaking stuff, or Dr. Wakeman has simply reinforced a lot of the house.
* EarlyInstallmentCharacterDesignDifference: In the original ''WesternAnimation/OhYeahCartoons'' pilot short, her hands were the same coloring as her hair and "clothes", she had lips, and her skirt had rivets on the bottom.
* FemBot: She's a female robot built with a feminine shape.
* GenkiGirl: She's quite excitable and with a positive attitude.
* GirlishPigtails: She has [[RobotHair metal protrusions on her head shaped like pigtails]]. She stores a rocket in each which she uses to fly, and they've been shown with other strange functions like antenna, blades, and ears.
* GirlyGirlWithATomboyStreak: She's has a love for clothing, pretty boys and shopping, and has an overall feminine demeanor, but she's also a proud ActionGirl loaded with weapons [[OneOfTheBoys whose friends are mostly male]].
* TheHeroine: The series revolves around Jenny who was created by her mother, Dr. Nora to protect Earth.
* HeroWithBadPublicity: Despite saving the world multiple times, the citizens of Tremorton still treats her like garbage.
* HeldBackInSchool: Jenny is sent to kindergarten on one occasion because she is technically only 5 years old.
* HugeSchoolgirl: She's stated to be 6' 6".
* IJustWantToBeNormal: Combined with IJustWantToHaveFriends: Being a superpowered robot wouldn't be so hard for her if there were more bots as advanced as her.
* JerkWithAHeartOfGold: She often shifts between this and NiceGirl, depending on whether the episode is making liberal use of SurroundedByIdiots.
* JetPack: Not so much as one as a flying robot, as she has rockets as part of her body. She can also transform herself into one.
* LightIsGood: A white robot and [[TheHero The Heroine]].
* LightningBruiser: She possesses super strength and speed.
* LovesMyAlterEgo: Jenny just considers Sheldon her friend, but falls in love with Silver Shell almost immediately ([[SpringtimeForHitler despite Sheldon trying to make him as repulsive as possible]] so she'd dislike robot guys). Eventually, he dates her as the Silver Shell, but she ends up hating him because he keeps sneaking off (to hide that their dance was being crashed by the space bikers) and Sheldon decides he'll have better luck with Jenny as himself.
* MagicalGirlfriend: The components of the fantasy are all there; Sheldon, the {{Nerd}} LoserProtagonist, falls in love with the SuperHeroine {{Fembot}} who saves him from bullies, and becomes her DoggedNiceGuy. Too bad she's not interested (although WordOfGod says that she ''would'' have become his girlfriend if the series had continued).
* MagicSkirt: Justified, as that "skirt" is made out of metal and is actually her pelvis.
* MeaningfulRename: Calling herself "Jenny" reflects her desire to be seen as a teenager rather than a machine. Nora usually calls her XJ-9, except during heartfelt moments.
* {{Omniglot}}: She has software that apparently allows her to speak any language, though we just see her speaking English [[TheCastShowOff and Japanese]].
* PinocchioSyndrome: Averted - she's perfectly fine with being a robot, but wants acceptance and assimilation... which sometimes means playing the trope straight.
* PlatonicLifePartners: With Brad. In fact, Jenny is just about the only girl who Brad doesn't show any kind of interest in or who shows any interest in him.
* RidiculouslyHumanRobot: Jenny thinks, emotes, cries, sleeps, and eventually dreams like a human. About the only humanlike thing she can't do is [[EatingMachine eat]] anything besides oil.
* RobotGirl: An American twist on the trope: Jenny is less interested in saving the world than hanging out with high school kids.
* RobotHair: She sports a pair of metal pigtails. They house two of her jet thrusters.
* SingleWomanSeeksGoodMan: She's sick of smooth operators, and wants someone sweet and sincere. Sheldon walks by, and she greets him, still wondering where she can find someone like that. There are hints that Jenny will eventually pick Sheldon. Confirmed by WordOfGod after the series' cancellation.
* SlidingScaleOfRobotIntelligence: Average Joe: Emotionally, she's basically like a human teenager--which is to say she can be very mature or [[BrattyTeenageDaughter very childish]] depending on the situation. Intellectually, it seems to [[DependingOnTheWriter vary by the episode]] whether she's a lot smarter than most humans, or basically just like a human with a built-in calculator.
* SheCleansUpNicely: Who knew that a teenage robot got a spa from ''greasy gearheads'' in order to visit Don Prima's party and in one episode, dresses herself in a variety of fashions to outdo ''the Crusts''?
* SlapstickKnowsNoGender: She tends to suffer more injuries than the rest of the cast.
* StatuesqueStunner: She's 6 1/2 feet tall (though this seems to include her hair) and really cute to boot.
* {{Stripperiffic}}: She wears a very small tanktop with a miniskirt, showing off a large amount of her body. Granted, it's made out of metal.
* SuperStrength: "The strength of a million-and-seventy men," if the theme song is to be taken literally. [[note]]If it is to be taken literally, that means Jenny should be able to bench press between 67,504 tons if the men used as reference are of average strength, and 551,038 tons if they're around the current human limit.[[/note]]
* TelescopingRobot: She provides the trope picture.
* WakeUpGoToSchoolSaveTheWorld: Pretty much her daily life, though the school bit is new.
* WeaksauceWeakness: Water tends to fry her circuits or rust her skin.
* WhatTheHellHero: In "Escape From Cluster Prime" her irresponsible handling of the Cluster Bomb causes an Earthquake which angers the whole town. In "Weapons of Mass Distraction" she refuses to fight crime because she's on a date, which backfires when her date calls her selfish for doing so and breaks up. In "Mist Opportunities" Sheldon calls her out for slacking off and letting Misty be the town's savior, despite Misty's shady character, and in "No Harmony with Melody" Brad calls her out for [[spoiler: trying to kill Melody, who she mistakenly thinks is a villain]].
* YoungerThanSheLooks: Technically has been alive for about 5 years, but has all the mentality of a teenage girl... usually. Jenny being physically five years old was even played as a joke, where a truant officer threw her into Kindergarten for the majority of the episode "I was a Preschool Dropout".


[[folder:Brad Carbunkle]]
->Voiced by: Melissa Denton (''Oh Yeah! Cartoons'' pilot), Chad Doreck

Jenny's best friend and next-door neighbor.
* ActionSurvivor: He's a completely normal human, but he helps Jenny take on intergalactic threats regularly, and even sometimes joins her on the front lines.
* {{Adorkable}}: Considers himself to be smooth and charismatic, but is really just an awkward, lovable teen.
* AnimeHair: He has three large spikes in his hair. He uses a lot of hair gel to get it that way.
* BadassNormal: No super powers to speak of, but still occasionally manages to be useful in battle.
* CampStraight: Brad is rather metrosexual, but shows exclusive (and [[CasanovaWannabe frequent]]) interest in women.
* CasanovaWannabe: Brad frequently insists he's irresistible to the ladies, which always causes any girl present ([[PlatonicLifePartners but Jenny]]) to turn their nose up at him.
* ChickMagnet: While Brad's game with ''human'' girls is pretty dire, he seems to have no problem attracting the attention of aliens and robots. [[UnwantedHarem Pretty much none]] [[AbhorrentAdmirer of it is wanted]].
* CoolLoser: Brad has a fairly cool demeanor and a decent fashion sense, but is implied to be pretty low on the social ladder.
* CrouchingMoronHiddenBadass: His over-enthusiasm for trying to be a hero can be more trouble than help, but when he gets serious he can be a pretty reliable ally.
* DistressedDude: His gung-ho attitude frequently results in him needing to be rescued.
* TheFace: While he's nowhere near as popular as he thinks he is, Brad is quite charismatic, and is able to function in social situations where [[NoSocialSkills Jenny]] can't.
* FearlessFool: Tends to leap headfirst into action despite almost always being way out of his depth.
* FieryRedhead: He has dark red hair and is quick to leap before he looks.
* {{Foil}}: To Jenny. While Jenny is super-powerful, but extremely self-conscious and [[IJustWantToBeNormal would rather be a normal teenager]], Brad is an ordinary guy who is extremely self-assured and [[IJustWantToBeSpecial desperately wants to be anything but a normal teenager]].
* GlorySeeker: Brad's primary goal in life is to be popular. He doesn't care what form this popularity takes, and pursues becoming a sporty jock, a famous musician and a world-saving superhero with equal amounts of enthusiasm.
* IJustWantToBeSpecial: In contrast to Jenny's desire to be a normal teen, Brad wishes that he could be a super hero, which causes him to tag along to help her fight evil frequently.
* InterspeciesRomance: Brad seems quite prone to this, considering his short relationship with Melody and his implied relationship with Misty.
* TheLoad: Particularly in earlier episodes, he tends to only get in the way or get captured when he tries to help Jenny out. Pretty much averted later on, as he pulls his weight much more consistently.
* MuggleBestFriend: He's an ordinary human who is best friends with a super-fighting robot.
* NiceGuy: Brad is typically a very friendly, upbeat person.
* TheNotLoveInterest: He's Jenny's best friend and usual {{foil}}, but their relationship is entirely platonic.
* PlatonicLifePartners: With Jenny. In fact, Jenny is just about the only girl who Brad doesn't show any kind of interest in or who shows any interest in him.
* RedheadsAreUncool: Isn't too popular at his school.
* RidiculouslyAverageGuy: Though he wishes to be more.
* SmallNameBigEgo: Brad thinks of himself as a cool, charismatic social butterfly as well as an accomplished adventurer. In reality, he's a clumsy, unpopular teen who thinks too highly of himself.
* TookALevelInBadass: After training in the Skyway Patrol, he becomes more consistently reliable during action sequences.
* UnfazedEveryman: Generally handles supernatural encounters with a combination of neutrality and enthusiasm.
* WeirdnessMagnet: The supernatural and the extraterrestrial seem to be naturally drawn towards him.

[[folder:Tuck Carbunkle]]
->Voiced by: Audrey Wasilewski

Brad's little brother.
* AnnoyingYoungerSibling: Tuck can sometimes be annoying, mostly because he's such a [[LargeHam scream]] [[LovableCoward queen]], though it doesn't seem to hurt his popularity in-universe. Brad even claims, when talking about Kilgore and Tuck, that "annoying + small = popular".
* BadassAdorable: He knows almost as much as Dr. Wakeman about robots.
* CheerfulChild: Tuck is very enthusiastic and smiles [[PerpetualSmiler almost constantly]].
* DistressedDude: Even more than his brother.
* JerkWithAHeartOfGold: DependingOnTheWriter, he's either a self-centered brat or a well-meaning kid who has trouble understanding boundaries. Sometimes at the end of the episode, he does something unselfish, other times he doesn't learn anything.
* KidAppealCharacter: Despite being a kids' show, the main cast is almost entirely teenagers, so Tuck fills in the much-needed role of a kid character.
* KarmaHoudini: In several episodes his selfishness causes destruction and pain for the main heroes, but he gets off relatively free.
* KidsAreCruel: His treatment of Jenny, Sheldon, and Brad can get downright brutal.
* LackOfEmpathy: One of his major flaws, DependingOnTheWriter. He regularly takes advantage of and humiliates his friends like in "Tuckered Out" and "The Boy Who Cried Robot" and shows little regard for their safety like in in "Histrionics". In "Ball and Chain" he doesn't care about his brother being forced into a marriage with a fish monster, only seeing it as an opportunity to have adventures in space.
* LargeHam: He's got quite a pair of lungs for a little guy and puts them to use.
* LovableCoward: He's the most likely to start running and screaming in any situation.
* OnlySaneMan: Slides in and out of this if the situation calls. Conversely, [[DependingOnTheWriter in a few episodes]] he's a pushy jerk.
* TakingAdvantageOfGenerosity: A few episodes have been based on Tuck abusing Jenny's protective nature or his friends' general wishes to help him because he's younger. [[LaserGuidedKarma This generally doesn't end well for him.]]
* WholesomeCrossdresser: He wears a dress and a necklace in "Labor Day".
-->'''Tuck:''' What? Can't a guy wear pearls and taffeta around here?\\
'''Nora:''' Strictly speaking, only after 6.

[[folder:Dr. Nora Wakeman]]
->Voiced by: Creator/CandiMilo

An elderly spinster robotics scientist and the one who built the XJ robots, who is often simply refers to as "Mother" or "Mom" by Jenny and her sisters.
* ActionMom: When in danger, she shows no reluctance in fighting.
* AmazinglyEmbarrassingParent: Anytime Nora talks to a peer of Jenny besides Brad and Tuck, expect to her some embarrassing detail about Jenny's design or maintenance.
* CoolOldLady: She even fought Vexxus with her bare hands!
* DefrostingIceQueen: Was once very, ''very'' strict about Jenny's lifestyle and initially desired to keep her out of the public eye when not fighting evil. She eventually comes around however to embrace Jenny's very humanlike nature and now lets her live as the typical teenage girl she designed her to be, allowing Jenny to interact freely with humans.
* GadgeteerGenius: She's built [[DoAnythingRobot incredibly powerful]] RidiculouslyHumanRobots as well as other machines.
* GenkiGirl: She comes off as a lively and excitable woman. [[ItRunsInTheFamily No surprise where Jenny gets it from.]]
* EarlyInstallmentCharacterDesignDifference: She had a different hairstyle and her clothes were completely white in the pilot short on ''WesternAnimation/OhYeahCartoons''.
* EinsteinHair: Her hair is white, spiky and messy
* GagNose: While it isn't pointed out often, in TheMovie Sheldon calls her a "birdnose" and later she uses it to poke Vexus's eye.
* MadScientist: One of the saner ones, but some of her inventions and experiments seem to serve no clear purpose.
* MamaBear: Jenny is certainly a powerful robot who can take care of herself, but that won't mean that Nora will tolerate anyone threatening Jenny while she's around. Especially since she's a RetiredBadass
* MeddlingParents: One episode had her remove Jenny's ability to hang-up on her
* MotherlyScientist: Jenny calls her "mom" and Dr. Wakeman certainly does view her as her daughter.
* NeverMessWithGranny: She [[RetiredBadass used to be part of the Skyway Patrol]] prior to the series. Even in present-day she's far from any definition of "weak".
* OlderThanTheyLook: She looks old enough to have grandchildren; she also has a de-aging machine which shaves decades off with each use. The casual air with which she mentions this implies it's been used many times.
* TheProfessor: She created Jenny and tends to provide her with upgrades and gadgets of her own design to help Jenny take on tough opponents.
* SiblingYinYang: With her sister, Wisteria. While Nora has a scientific, logical and mechanical view, Wisteria is more based on nature and was a flower child with potential mystic elements. Also telling in their children, Nora's robot daughter and Wisteria's PlantPerson son, Glenn.
* ShipperOnDeck: When Nora first sees Sheldon and everyone is assuming he's Jenny boyfriend, she immediately expresses approval, mostly because he's a gangly scientist-type like her.
* TrulySingleParent: Nora considers XJ-9 her daughter (the other XJ robots somewhat less so), and despite Brad and Tuck always calling her "Mrs. Wakemen", she's never been married.

[[folder:Sheldon Lee/Silver Shell]]
[[caption-width-right:350:Click [[labelnote:here]]http://static.tvtropes.org/pmwiki/pub/images/silver_shell.png[[/labelnote]] to see Silver Shell]]

->Voiced by: Creator/QuintonFlynn

Jenny's self-proclaimed romantic admirer.
* AbhorrentAdmirer: Towards Jenny at first, but mellows out of his stalking in later episodes and she starts to enjoy his company.
* AcePilot: He's shown to be capable of flying alien spaceships competently.
* {{Adorkable}}: He is quite geeky, but he is a very kind, if somewhat awkward, towards Jenny. And that's what makes him quite endearing.
* AgentPeacock: When he joins the secret agency, his codename is "Baron Von Fashionista III".
* AmbiguouslyBi: In one episode he has a conversation with Jenny discussing which members of a Boy Band is the cutest.
* AsianAndNerdy: While his ethnicity isn't confirmed in the show, his surname suggests an Asian background and the Japanese citizens shown have similar skin tones and facial features as him.
* AwesomeButImpractical: He likes to go about things in a needlessly complicated way. In the beginning of "Shell Game", he uses a gun-like gizmo which extends small appendages to open a soda bottle just so he can use the bottle cap with which to hit Jenny, distracting her long enough for him to stand before her. [[ItMakesJustAsMuchSenseInContext Yeah.]]
* BigBrotherInstinct: They're not related, but he was very protective of Tuck in "A Pain In My Sidekick", trying save him from enemies and crying when he thought Tuck might have died at the end of the episode.
* ButtMonkey: Suffers quite a bit over the course of the series.
* ChivalrousPervert: Towards Jenny. It may seem sometimes that he's only interested in Jenny's robot abilities and design, but in other episodes proven otherwise. For example, once Jenny wanted him to remove all her equipment, and he complied (although reluctantly) and spent hours on end removing all of it despite knowing how she would look afterwards.
* ClarkKenting: Despite rather blatant evidence that Silver Shell is him (the similar names, it's just a "shell" he pilots, and the head crest that looks like Sheldon's hair), no one ever suspects this.
* CrouchingMoronHiddenBadass: Despite frequently prat-falls and his nerdy appearance, Sheldon eventually shows himself to be rather competent, managing to sneak past the Wakeman's security system, help Nora board a Cluster warship, live as space pirate (eventually a captain) [[spoiler:''for decades'']], and even spent a while as a secret agent.
* {{Deuteragonist}}: Later in the series, he's arguably more in-focus than anyone but XJ-9 herself.
* DistressedDude: Though [[TookALevelInBadass this becomes less frequent later on]].
* DoggedNiceGuy: Several times his sincere and friendly attitude have gotten Jenny's affection, [[FailureIsTheOnlyOption only to lose it]] because of a misunderstanding or because Jenny found out something very ''un''pleasant that he'd done recently.
* DudeWheresMyRespect: It's not that he can't ever get any respect, but he has to work ''much'' harder for it.
* ForgottenPhlebotinum: Sheldon treats the Silver Shell suit only as a means to get closer to Jenny. He never thinks of using it for anything else, like defending the Earth from the Cluster when Jenny is MIA in the movie. After Jenny loses her infatuation with the Silver Shell, he only uses it once more, when Tuck finds the thing in his garage.
* GadgeteerGenius: He's created functioning PowerArmor, his own robots (though nothing as [[RidiculouslyHumanRobots human-like]] as Nora's), new gadgets for Jenny to use, and a functioning time machine.
* HatesMySecretIdentity: Sheldon creates the superhero identity of Silver Shell so Jenny will date him (and to convince Jenny to date him for real). It eventually backfires when she gets frustrated with the Shell and traps Sheldon in a web of lies.
* HeroWorshipper: A variant in that he's smitten with XJ-9 as well as seeing her as a role model.
* InTouchWithHisFeminineSide: Sheldon's not exactly a masculine type, and he has interests in Fashion Magazines and Boy Bands.
* InterspeciesRomance: Sheldon's crush on Jenny.
* LargeHam: As the Silver Shell, he has melodramatic and hammy dialogue to play up his being a superhero.
* OlderThanTheyLook: [[spoiler:The events of "Good Old Sheldon" ended with him physically 15 years old, but '''105''' chronologically and mentally--and he remembers ''all'' of it.]]
* OnlySaneMan: At times. In "Mist Opportunities" he's the only one to call out Jenny for letting Misty be the town's hero, despite the first time she showed up she left the Earth when it was under attack because she felt like it. In "Historionics" Jenny and Brad were infatuated with Wizzly, but Sheldon reminds them that Wizzly's animatronics were trying to kill them.
* RescueRomance: Sheldon meets and falls hard for Jenny after she saves him from some bullies in shop class.
* {{Robosexual}}: He's a human who has a crush on Jenny, a robot. Vexus uses this to her advantage in "Designing Women", wherein she disguises as a robot girl to distract him long enough to get the XJ9 blueprints he stole from Nora. It ''works''.
* SingleTargetSexuality: Jenny is the only person he's attracted to.
* StalkerShrine: He has an unsettlingly large colletion of pictures of Jenny in his closet and his locker.
* StalkerWithACrush: In his introduction episode he was definitively this, but in later episodes he is more friendly and helpful towards Jenny.
* StrongButUnskilled: As the Silver Shell his fighting style is rather sloppy but the suit is strong enough for him to last.
* ThrowTheDogABone: a few episodes end up well for him. In the Christmas special Jenny finally gives him a kiss. She gives him another in "Agent 00' Sheldon" although [[YankTheDogsChain starts attacking when she found out he was spying on her]]. Also in "The Price of Love" it's revealed in 20 years he'll become a billionaire.
* TookALevelInBadass: Started off as a meek nerd who could barely defend himself against bullies. In later episodes he's much from being a space pirate captain to a secret agent. Go figure.
* UndyingLoyalty: In the Christmas episode, he's the only person to stay by Jenny's side when the entire town has turned against her by this point.
* WhatDoesSheSeeInHim: Not Sheldon himself, but Jenny is infatuated with his alter-ego the Silver Shell. Sheldon deliberately acted like a jerk to turn Jenny off dating robots, but it backfired. In later episodes Jenny would get irritated enough at the Shell because of his obnoxiousness, but continues to admire him the next time he appears.
* YankTheDogsChain: There are a few moments where he comes close to gaining Jenny's affection only for it to be ruined in the last moment due to a misunderstanding or his prior actions biting him in the ass.

[[folder:XJ-1 through XJ-8]]
[[caption-width-right:350:Clockwise, beginning center: XJ-4. XJ-6, XJ-5, XJ-1, XJ-8, XJ-7, XJ-2, XJ-3]]
->Voiced by: Creator/JaniceKawaye (XJ-1), Creator/KathSoucie (XJ-2, XJ-3, XJ-4 and XJ-5), Creator/CandiMilo (XJ-6), Audrey Wasilewski (XJ-7 and XJ-8)

XJ-9's prototypes and "sisters".
* BigLittleSister: XJ-8 is much larger than Jenny despite being considered her younger sister. She is technically ''also'' older (which would make XJ-1 the LittleBigSister), though Jenny seems to have spent the most time online.
* BreakOutTheMuseumPiece: Once, after Jenny got captured by the Cluster, she sent out an emergency beacon that reactivated them. With the exception of XJ-8 they don't appear to be combat-ready, but do okay as they apparently have the same [[TelescopingRobot telescoping armor]] Jenny does.
* CombiningMecha: Not exactly in a true "mecha" sense, but they do have the ability to join together to form various weapons along with the "Robo Wall".
* CuteClumsyGirl: XJ-3 constantly trips and [[EasilyDetachableRobotParts falls apart]].
* CyberCyclops: XJ-3 has one physical eye that sits on top of her body while XJ-6 has a [[TVHeadRobot computer display face]] that shows one eye.
* TheEeyore: XJ-7 is constantly depressed, even lamenting that she couldn't ''destroy herself'' properly.
* FlawedPrototype: All of them. Unlike most examples of the trope, though, they are clearly functional testbeds that do well within the parameters of their design.
* FrickinLaserBeams: XJ-2 is basically a laser gun with legs and eyes.
* GreenEyedMonster: Everyone word XJ-6 says is complaining about someone else, usually Jenny, getting more attention than her. Bonus points for her eye actually being green.
* HiccupHijinks: XJ-2 constantly hiccups, causing her to misfire.
* MachineMonotone: XJ-8 speaks like this, though the tone changes depending on the episode.
* MotorMouth: XJ-5 sounds like a used car salesman and never, ever stops talking. Justifiable in a sense; from the look of her eyes and her speaker mouth she may have been constructed using parts from a radio, and radios NEVER stop broadcasting.
* NeatFreak: XJ-4 compulsively cleans everything she sees.
* RidiculouslyHumanRobots: The XJ sisters appear to be gradually working towards this. May also be why XJ-8 isn't the last in the line.
* SlidingScaleOfRobotIntelligence: Most of them are Average Joe like Jenny, but XJ-1 and XJ-2 are closer to Robo-Monkeys, being like a human baby and toddler, respectively. XJ-8 is also a lower-level Average Joe than the rest, being very blunt and thuggish.
* SuperPrototype: XJ-8 is physically stronger than Jenny--to the point that she's really not looking forward to fighting her--but doesn't have Jenny's "quirk and charm" according to Dr. Wakeman. Being [[NoSocialSkills so terrible at talking to people]] still makes her a FlawedPrototype even in terms of being a superhero, as she, for instance, thought children breaking a pinata were committing a crime.


[[folder:Queen Vexus]]
->Voiced by: Eartha Kitt, Creator/CreeSummer ("Around The World in 80 Pieces")

The tyrannical queen of the Cluster who constantly tries to get Jenny to go with her to her homeworld of Cluster Prime through immoral means.
* ArchEnemy: Vexus to Jenny, and vice-versa. Vexus isn't even happy with conquering Earth unless Jenny is there to see it.
* AttentionWhore: Has devolved into this by season 3, where she's overjoyed to be worshiped by the entire school ever since she lost her planet.
* BadSamaritan: She claims to be a liberator of machines, though her definition of "liberation" is merely a sugar-coated "assimilation into our collective".
* BeCarefulWhatYouWishFor: Spends most of the first and second seasons trying to bring Jenny to Cluster Prime. And what happens when she actually gets there?
-->'''Cluster Prime''': Down with Vexus! Down with Vexus! Down with Vexus!
* BeePeople: She resembles an insect of some sort.
* BigBad: Vexus is the main villain for the entire show.
* BitchInSheepsClothing: Has a tendency to disguise herself and put up the impression of an understanding friend or a normal human being. She does this to Jenny, Sheldon, even the entirety of Tremorton High at one point.
* BreakTheHaughty: She eventually [[spoiler:loses her dictatorship over Cluster Prime, reducing her to a madwoman living on a garbage planet and talking to the creatures crawling around it]]. [[UnexplainedRecovery She's mostly back to normal]] by the end of the season and menacing Jenny as usual, though [[spoiler:without her empire behind her, she's significantly less of a threat.]]
* BrokenPedestal: Toward her daughter Vega, who never believed she was downright evil. Upon learning the truth, she helps Jenny overthrow her own mother.
* {{Determinator}}: Even after losing multiple times to Jenny [[spoiler:even to the point of losing her status as Queen]], she still insists on attacking Jenny any chance she gets.
* EvenEvilHasLovedOnes: She genuinely cares about her people. Jenny even exploits this at one point when Vexus had captured Tuck, forcing her to make a hostage exchange for one of her mooks.
-->'''Mook:''' Mama!\\
'''Vexus:''' ''(horrified)'' My baby!
* EvilMatriarch: Subverted. She may be evil and the BigBad of the show, but she still loves Vega (almost to the point of being [[MyBelovedSmother overprotective]], even.)
* FantasticRacism: Doesn't much like humans, even calling them derogatory names like "flesh wearers".
* FauxAffablyEvil: She is usually polite to Jenny, even while trying to destroy her or assimilate her into the Cluster.
* GalacticConqueror: Being the leader of an interstellar robot extremist empire bent on enslaving the human race, she certainly qualifies.
* GodSaveUsFromTheQueen: Cluster Prime's residents are actually good-natured, but they are forced to obey Vexus or be destroyed.
%%* HellishPupils
* HiveQueen: If her queen bee motif didn't give it away, she's the head of a collective of bug themed robots.
* HowTheMightyHaveFallen: After losing her empire in season 2, she's much less of a threat without her army behind her, and even devolves into insanity at one point. She gets better, but it hardly helps that she is still alone in her endeavors against Jenny.
* {{Hypocrite}}: She and the Cluster in general insist humans are unjustly controlling Earth's machines, yet she's quite the tyrant herself, and will gladly use mind control to force those same machines to join the Cluster, willing or not.
* JoinOrDie: Her general philosophy when it comes to assimilating robots into the Cluster.
* LaserGuidedKarma: Being a deceptive tyrant who tries to force Jenny to join the Cluster and enslave humanity, it's only fitting that she loses her entire planet in the process.
* ManipulativeBitch: She relies on cunning and subterfuge to accomplish her goals. One notable example, is her using Sheldon to acquire Jenny's blueprints for herself, so as to predict her weapons and counter them effectively. And that's not even getting into her propaganda campaign to keep her subjects ignorant of her true nature, while demonizing Jenny.
* NotSoDifferent: For someone who despises humanity and boasts about robot superiority, she herself possesses some of their worst traits, being a dictator and all.
* OverarchingVillain: She is present for the entire show, appearing every season and always hatching some scheme to enslave humanity.
* RevengeBeforeReason: In "Trash Talk" she plans to blow up the planet Jenny is on, despite being on the planet herself and not having a viable way off.
* SanitySlippage: In "Trash Talk" she becomes noticeably more insane, planning to blow up a planet she's on and escaping on a pod that can only fit a hamster. She gets better by "Queen Bee".
* TakeOverTheWorld: Pretty much her entire plot in a nutshell.
* TotallyRadical: She would have blended in while she was destroying Jenny if she only realized that TheRoaringTwenties was over for almost a century now.
* TsurimeEyes: Her eyes are slanted upwards.
* VillainousBreakdown: She remains fairly composed for most of the series, but she ''really'' starts to lose it when Jenny turns her entire planet against her rule. By the time of "Trash Talk", she's been reduced to madness, trying to use some random scraps of garbage to build an escape pod and referring to Krackus and Smytus with nonsensical names.
* WeCanRuleTogether: She makes this offer with Jenny, trying to get her to help her robot brethren and destroy the human race. You can guess what Jenny's answer was.

[[folder:Commander Smytus]]
-->Voiced by: Creator/SteveBlum

A large green robot from the Cluster who seems to have ties to its military division.
* BadassBaritone: Comes with being voiced by Steve Blum.
* BadassBoast:
-->'''Brad''': We can do it! We can stop them! We haven't met a robot yet we can't destroy!
--> '''Smytus''': Then you haven't met ''me''!
* BadBoss: His answer to one incompetent minion causing him to lose the Pip crystals? ''[[ThrownOutTheAirlock Throw his entire crew out the airlock]]''.
* BigCreepyCrawlies: Resembles an anthropomorphic rhinoceros beetle
* BrokeYourArmPunchingOutCthulhu: Even after he [[spoiler: successfully takes over Earth with the Cluster]], he winds up without a lower body. Krackus had to build him a few replacements out of trash.
* TheBrute: As expected, he serves as the physical driving force of Vexus' army. Their methods of inducting Jenny into the Cluster even vary; Smytus relies more on force while Vexus uses cunning and subterfuge.
* CardCarryingVillain: If his "''DESTROYER OF WORLDS!''" speech is anything to go by, he ''really'' enjoys being a villain.
* TheDragon: Smytus serves as one to Vexus.
* DragonTheirFeet: After Vexus is defeated in the Escape From Cluster Prime special, Smytus is still threatening to destroy Earth. He doesn't get very far.
* DudeWheresMyRespect: In his first appearance, he laments that Vexus gives him demeaning nicknames.
* EvilGloating: Thanks to his ego, he will engage in this any chance he gets.
* EvilIsHammy: As demonstrated on IncomingHam below, he has the subtlety of a sledgehammer to the face.
* EvilLaugh: Goes hand in hand with his LargeHam. He's very fond of these.
* EvilSoundsDeep: Not as deep as some of Blum's other roles, but still fairly low-pitched.
* FantasticRacism: Like the rest of the Cluster, he doesn't hold "fleshbags" in very high regard.
* GeneralRipper: The leader of the Cluster's armies and not a villain to be taken lightly.
* HalfTheManHeUsedToBe: The explosion in Escape From Cluster Prime reduces him to a torso forced to walk on makeshift legs, cobbled together from junk.
* HyperCompetentSidekick: To Vexus in Escape From Cluster Prime. Vexus is far too occupied with Jenny to even carry out the invasion, until Smytus eventually gets fed up and takes charge himself. He actually succeeds, and when the humans start fighting back, he simply settles for destroying the planet instead.
* IncomingHam: "Bow to me, mortal, and tremble in fear! Before you stands Smytus, lord of the outer rims, mayor of moon robia, cappo of the cram nebula, and '''DESTROYER OF WORLDS!'''" ''(cue DramaticThunder)''
* IneffectualSympatheticVillain: In season 3, he's left as a pathetic wreck who mostly just wants to get [[spoiler:his legs]] back.
* IJustWantToHaveFriends: Played with. He perks up quite a lot when he's complimented by the humans, and he has to remind his minions to [[LaughWithMe laugh with him]] after he makes a short speech.
* LargeAndInCharge: He's bigger than most of the established Cluster villains, and is their military commander.
* NotQuiteDead: [[spoiler:At the end of "Escape From Cluster Prime", he's at the center of an explosion that was supposed to destroy all of Tremorton. By the next season, he's lost his legs, but is still alive.]]
* PaperThinDisguise: He puts on a wig and tries to pass himself off as Smytlana, a Ukrainian supermodel, after his attempt to break into a fashion designer's private boutique goes awry because the secretary called him fat. After a short while of being complimented, ''[[BecomingTheMask he falls for the disguise himself]]''.
* SelfDestructMechanism: He has one literally stored in his sleeve. Of course, it comes with a ten second countdown, as well.
* SmallNameBigEgo: Zig-zagged. Although he's the commander of the Cluster military, he doesn't appear to garner much respect from his superiors. Best example comes from when the Crusts shrink him and he's left scrambling while boasting about his status as a Cluster champion.
-->'''Smytus''': I ''am'' a warrior! I ''am'' a destroyer of worlds!
* SmugSnake: He's a fairly capable villain, all things considered, but he vastly overestimated his abilities, which tends to be his undoing.
* SoreLoser: Has some shades of this. Main example comes from when the XJ-sisters are able to free Jenny from his control, and he almost throws a tantrum.
* SurroundedByIdiots: His opinion of the drones under his command.
* TakingYouWithMe: Attempts to self-destruct and take as many humans with him as possible. It doesn't work quite the way he intended, [[WhatAnIdiot as he conveniently gave Jenny ten seconds to stop him]].
--> '''Smytus''': Not so fast, XJ-9. You may have destroyed my mega-weapon, and my ship, and my robot factory, and my troops, but I still have an ace up my sleeve. Literally! Self-destruct, baby! Every supervillain's last resort! Say goodbye to your beloved fleshbags! This ends now... in ten seconds!
* TopHeavyGuy: One of, if not the strongest of Vexus' minions.
* UncertainDoom: Smytus, Vexus, and Krackus were all present on the garbage planet when it blew up. Since Vexus returns later on, it's possible Smytus and Krackus survived as well, and may have reappeared had the series continued.
* VillainBall: He gives his self-destruct sequence a countdown, allowing Jenny enough time to throw his ship into orbit as it explodes. Woops.

-->Voiced by: Creator/JimWard

A senile, older Cluster robot who often bungles his experiments and forgets where he is all the time. His inventions almost never last for very long, but he's not one to give up easily.
* BewareTheSillyOnes: Like what Nora tells her daughter, "Don't underestimate him! Sooner or later he may invent something that actually works!"
* BigCreepyCrawlies: Bears a resemblance to a large beetle.
* BunglingInventor: Most of his inventions fall apart after one use.
* EvilGenius: Is the brains of the Cluster, though his subordinates think otherwise.
* EvilOldFolks: He seems mostly harmless, though.
* IneffectualSympatheticVillain: Shares this trope with Smytus in Season 3.
* InformedFlaw: He's treated as a joke by most characters, but all his appearances in the show has him use his inventions rather competently.
* MiniatureSeniorCitizens: He's the shortest member of the Cluster seen before the BigDamnMovie.
* NotSoHarmlessVillain: He's called one of the most incompetent members of the Cluster, even getting laughed at. Yet most of the time, his inventions work as intended and he is a legitimate threat.
* OnlySaneMan: In "Trash Talk" he's the only one who wants to use Jenny's fuel to power a spaceship to get off the trash planet. Vexus was fully insane and wanted to blow up the planet (despite having no way off), and Smythus wanted to get a new pair of legs despite the fact that he'd still be stuck on the planet.
* RobotHair: Has a metal mustache that also functions as a mouth in imitation of a beetle's mandibles.
* UncertainDoom: Krackus, Smythus, and Vexus were present on the garbage planet when it blew up. While Vexus was shown to survive, it's unknown what happened to Krackus or Smytus.

->Voiced by: Creator/TaraStrong

A small, adorable wind up robot from a toyline, Killgore somehow managed to attain sentience and decides to fulfill its purpose as a villain, first by joining the Cluster and capturing Jenny, then by destroying the Cluster ''and'' Jenny. Things don't always go as planned for him, however.
* BadassAdorable: He managed to outsmart Jenny twice and [[spoiler:rebuild Armagedroid, who is ''millions'' of times Killgore's size.]]
* BrattyHalfPint: He drives Jenny ''bonkers'' in his first appearance due to his constant pestering towards her.
* {{Catchphrase}}: '''Surrender''' and '''[[LeftTheBackgroundMusicOn "BA-NAH!"]]'''
* CardCarryingVillain: Killgore insists you read his tag!
* CuteIsEvil: He's considering the cutest thing ever in-series, and a CardCarryingVillain through-and-through. Jenny's biggest problem with facing him is that she can't fight back without people hating her for it.
* DeathbringerTheAdorable: Sure the name may sound threatening, but it's so gosh-darn cute!
* {{Determinator}}: Determination and cuteness are basically the only things he has on his side. He nearly ends up driving Jenny insane just by endlessly jumping at her while yelling "Surrender!"
* EnemyMine: With Jenny in "Enclosure of Doom".
* EvilSoundsDeep: Spoofed in the first few seconds of the episode he's introduced, as it's not wound up yet.
* {{Expy}}: Seems to be one of WesternAnimation/InvaderZim. He's a short hammy non-human with a high pitched voice and speaks in ThirdPersonPerson who wishes to please an intergalactic EvilEmpire by destroying mankind while having delusions of grandiose. He causes grief for the main hero, but nobody else seems to care for his villainy.
* HarmlessVillain: To the point where he was outright rejected by the Cluster.
* IneffectualSympatheticVillain: Once Jenny has a chance to destroy Killgore [[WhatYouAreInTheDark with no one being the wiser]], she decides she can't hurt a defenseless creature even if it's driving her crazy.
* InstantAIJustAddWater: Why a windup toy is sentient [[RuleOfFunny is not remotely addressed]].
* LaughablyEvil: He provides a lot of humor for wanting to be considered a threat while apparently oblivious of how most people find him adorable.
* MyLittlePanzer: As much as he claims otherwise, [[SubvertedTrope nothing about Killgore's design is dangerous]]--any danger he poses is instead a result of trickery and persistence.
* TheNapoleon: If its 10 1/2 inch stature has any indication.
* ScareChord: He keeps ''saying'' the classic "buh nah" chord.
* SayingSoundEffectsOutLoud: '''SMACK!'''
* ThirdPersonPerson: The mighty Killgore only refers to himself as "Killgore"!
* VillainTeamUp: [[spoiler:With Armagedroid in "Enclosure of Doom", it worked...[[TheOnlyOneAllowedToDefeatYou a bit too well]].]]
* VillainWithGoodPublicity: Sure it may not be threatening, but what part of "Villian" don't the people who take a liking to it understand? All of it, apparently.
* WindUpKey: It's powered by a watch spring and a wind-up key.

-->Voiced by: Creator/KevinMichaelRichardson

A gigantic robot created by Dr. Wakeman back when she was a Skyway Patrol member for the purpose of eliminating alien weaponry. It turned its attention to human weapons in peacetime, forcing Dr. Wakeman to lure it into the Earth's core where it remained- for the time being.
* AIIsACrapshoot: During peacetime, it turned on human weapons, giving itself the mission to destroy all weapons on Earth.
* BadassBaritone: A quality that often comes with being voiced by Kevin Michael Richardson, of course.
* CainAndAbel: He could conceivable be regarded as an "older brother" to the XJ line, being an earlier Wakeman robot that has a vaguely similar blue and white (but with a little black, too) aesthetic.
* DestructiveSaviour: Armagedroid, who was built for the purpose of eliminating dangerous weaponry. Something that proved to be dangerous in peacetime.
* EvilSoundsDeep: Courtesy of Kevin Michael Richardson.
* KilledOffForReal: In his second appearance he self destructs after realizing he's a weapon.
* KnightOfCerebus: Definitely not one of the more comical villains. He almost killed Jenny in their first battle!
* KnightTemplar: Wants to make the world a safer place...in a bad way that is.
* HumongousMecha: Taller than most of the buildings in Tremorton.
* RedEyesTakeWarning: Huge red ones.
* VillainTeamUp: [[spoiler:Was later somehow rebuilt by Killgore.]]

[[folder:The Space Bikers]]
[[caption-width-right:350:Clockwise, beginning left: Olga, Tammy, Letta, Lenny, and Sludge]]
->Voiced by: Creator/GreyDeLisle (Letta, Lenny), Janice Kawaye (Tammy), Candi Milo (Olga, Sludge)

A gang of five fish-like aliens who come to Earth every so often to cause chaos. They are Letta, Sludge, Olga, Tammy, and Lenny.
* AbhorrentAdmirer: Tammy is revealed to be attracted to Brad in "Ball and Chain" and even attempts to marry him. For the most part, Brad is very uncomfortable about Tammy's affections.
* AllBikersAreHellsAngels: They're first introduced as a gang of thugs who spend their lives partying and wreaking havoc in orderly places, but [[spoiler:in "Voyage to the Planet of the Bikers", it's revealed they're only like that on weekends and live as schoolteachers on their homeworld]].
* BareYourMidriff: Olga and Sludge wear clothes that leave their midsections exposed.
* BikerBabe: With the exception of Lenny, they're all female bikers. Tammy stands out in particular.
* ButtMonkey: Lenny tends to be regularly roughed up by Letta. And the bikers as a whole always suffer when they mess with Jenny.
* FishPeople: Their species sorta resembles the Creature from the Black Lagoon.
* GreenAndMean: They have green skin.
* HappinessInSlavery: Lenny is genuinely content being Letta's pet. He gives Brad a thumbs up when he suffers the same fate, and when his leash is cut the first thing he does is try to tie it back.
* HartmanHips: Tammy has very large hips.
* HugeGirlTinyGuy: Lenny is minuscule compared to all of the other Bikers, especially his wife Letta
* LaserGuidedKarma: In "Voyage to the Planet of the Bikers" they lose their teaching job after going after Jenny and Tuck on their motorcycles. They kind of deserve it for pranking Jenny by converting her into a motorcycle and soldering her joints so she can't return to her normal form.
* NonMammalMammaries: Despite being fish people, Letta, Sludge, and Tammy have breasts. Seemingly averted for Olga, though she appears to wear a crop top.
* TheNoseless: All of them except Tammy lack noses. Tammy turns out to have a nose when her full face is revealed in "Ball and Chain".
* TheOneGuy: Lenny is the only male in the group.
* PunchClockVillain: [[spoiler:They only come to Earth to raise mayhem on weekends as a way for blowing stress off from their jobs. Outside of that, they're perfectly decent, hard-working people.]]
* QuirkyMinibossSquad: For Jenny. They're a group of villains who constantly show up to cause trouble in Tremorton, only for Jenny to beat them with ease most of the time.

[[folder:Dr. Locus]]
-->Voiced by: Grant Albrect

An evil mad scientist who is the father [[spoiler:and creator]] of Melody.
* TheBadGuyWins: Killing the heroes aside, Dr. Locus successfully accomplishes his objective in "Bradventure" by copying Jenny's abilities and installing them into Melody.
* BaldOfEvil: He has no hair on his head.
* BeardOfEvil: He has a scruffy white beard.
* BitchInSheepsClothing: Initially presents himself as a kindly old man to Brad, but quickly drops the act once he realizes he can use him as bait to trap XJ-9
* BondVillainStupidity: Averts this by refusing to tell Brad his evil plan, though later he forgets he didn't.
* CreepyBlueEyes: One thing noticeable is that his eyes are blue instead of black like most other characters.
* EatenAlive: Gets devoured by Dr. Wakeman's garbage disposal machine in "Turncoats".
* EvilIsHammy: He enjoys gloating this way.
* EvilCounterpart: Like Nora Wakeman he's a MadScientist with a robot teenage daughter. Unlike Nora, he's doesn't treat his daughter with respect and is evil.
* EvilOldFolks: He's pretty old.
* GreenEyedMonster: The reason he's angry with Nora is because his inventions were less popular.
* KnightOfCerebus: He ultimately succeeds in his debut episode and he came rather close to kill both Jenny and her mother in the show's final episode.
* MadScientist: He's an inventor with questionable sanity and morals, though he insists he isn't.
* PragmaticVillainy: He refuses to tell Brad his evil plan. However later he seems to forget this and thinks he did, prompting him to try to kill Brad.
* TopHeavyGuy: He has a large broad torso and legs that are basically nubs.
* UnknownRival: Dr. Wakeman had no idea he existed until he showed up in the last episode.

!!Tremorton High

[[folder:The Crust Cousins, Brit and Tiff]]
[[caption-width-right:350:Brit (right) and Tiff (left).]]
->Voiced by: Creator/CreeSummer (Tiff), Moira Quirk (Brit)

The antagonists of Jenny's life in high school, they seek to humiliate her at every turn.
* AlphaBitch: They torment Jenny simply because a super-powered robot [[AttentionWhore would otherwise be more popular than them]].
* AttentionWhore: There was a whole episode that revolved around these two setting Jenny up to be splashed in oil because Jenny was getting more attention than them in her new design.
* AmbiguouslyBrown: It's not stated what Brit's ethnic background is, though Indian makes the most sense, considering her English accent and [[http://en.wikipedia.org/wiki/British_Raj Britain's past colonisation of India]]. She could also be South African for [[http://en.wikipedia.org/wiki/History_of_South_Africa the same reason]].
* BareYourMidriff: Tiff's normal costume. Some of Brit's fashions in "Victim of Fashion" do it as well.
* {{Bifauxnen}}: As demonstrated in the picture above, Brit appears somewhat androgynous at times.
* BritishTeeth: Downplayed by Brit, who simply has slightly goofy-looking buck teeth. One GrossupCloseup implies they're much worse than they look from a distance, though more crooked than dirty.
* BullyingADragon: Jenny is sweet, gentle, and kind. She wants to fit in with her peers, and is a generally good person. Brit and Tiff, however, don't ever seem to grasp that she's also a walking, talking, sapient weapons system capable of destroying entire space fleets on her own. However, it's [[JustifiedTrope justified]] since If Jenny retaliates, she'll most likely get in more trouble than Brit and Tiff will. Unlike Jenny, Misty does not care and would torment and hurt Brit and Tiff.
* TheDividual: Syndividual; they look very different and have some [[RedOniBlueOni contrasting personality traits]], but are almost always together and acting in unison.
* EeriePaleSkinnedBrunette: Tiff, which contrasts with her PrettyFlyForAWhiteGuy-style speech.
* EvenEvilHasLovedOnes: Brit and Tiff do seem to genuinely care about each other as cousins
* FatAndSkinny: Tiff and Brit, respectively. Tiff is more curvy than fat, but she still greatly contrasts [[NoodlePeople Brit]] physically.
* TheFashionista: Both of them have impeccable dress sense, and are always seen wearing a new trendy outfit whenever they appear.
* FutureLoser: In "The Price of Love" we see that in 20 years Brit and Tiff will become poor and ugly.
* GirlyGirlWithATomboyStreak: Downplayed with Brit. While she occasionally dresses in an [[{{Bifauxnen}} androgynous]] style, she otherwise possesses the standard [[AlphaBitch haughty queen bee]] personality, and frequently wears very feminine clothing.
* HartmanHips: Tiff sports a pair.
* HeelFaceDoorSlam: In their first appearance, Brit and Tiff actually defended Jenny when the police were planning on bringing her downtown after the science lab caught on fire (which they caused), as thanks for saving their lives. They actually wanted Jenny to start hanging out with them, until Brit shook Jenny's hand too hard and dislodged the hair pin Tiff shot into it. As the two were being led away by the police, they blamed Jenny for it.
* HoistByHisOwnPetard: More than one of their schemes have terribly backfired.
* LeanAndMean: Brit is both tall and incredibly skinny. She is also generally portrayed as the leader of the two. In comparison, Tiff is noticeably short and curvy.
* MeanBrit: Brit has [[IAmVeryBritish the accent]] and the attitude, though one wonders if she's actually British [[{{Fauxreigner}} or not]].
* MeaningfulName: Brit speaks with a British accent, and a "tiff" is a kind of petty squabble, which the two frequently instigate.
* NoodlePeople: Brit is very tall and skinny, which stands out opposite the short and curvy Tiff.
* PrettyFlyForAWhiteGuy: Tiff is very pale-skinned, but speaks almost exclusively in slang. This is made even more noticeable when opposite Brit, who speaks with a refined British accent.
* RedOniBlueOni: Brit is more soft-spoken, cold and manipulative while Tiff is more loud, brash and aggressive.
* TheQuisling: Sided with the Cluster after they invaded Earth in "Escape from Cluster Prime", advising who and where to find people to enslave. Once it looks like the Cluster are losing, [[ChronicBackStabbingDisorder they switch back just as quickly]].
* {{Spoiled Brat}}s: They're filthy rich, attention-seeking, have the crowd wrapped around their fingers, picking on poor Jenny and overall getting their way....most of the time.
* ThoseTwoBadGuys: A pair of [[AlphaBitch queen bees]] with a habit of tormenting Jenny Wakeman.
* UnlimitedWardrobe: They both wear new outfits in every episode they appear in. Sometimes, they wear multiple outfits in a single episode. No matter the case, they're never seen wearing the same thing twice.

[[folder:Don Prima]]
-->Voiced by: Creator/QuintonFlynn

The most popular boy in school. Jenny used to have a crush on him.
* TheCasanova: Implied to have gone on brief dates with most girls in the school.
* JerkJock: A total hunk, but also a total douche.
* {{Jerkass}}: He regularly insults and belittles the unpopular kids and only saw Jenny as a girl to date on his list.
* MeaningfulName: His name is a play on "prima donna", which means a person with high expectations and an inflated ego who gets angry when their expectations are not met.
* WhatDoesSheSeeInHim: Thankfully Jenny seems to have lost interest in him after she sees he cared more for his shoes than her.
* WildTeenParty: He throws one in ''The Great Unwashed''.

-->Voiced by: Candi Milo

The best friend of Brit and Tiff who's often seen accompanying them.
* TheBeard: As a part of Sheldon's OperationJealousy.
* BerserkButton: When people pronounce the "p" in her name.
* BetaBitch: Seems to be next in the social status after Brit and Tiff
* ADayInTheLimelight: She's usually just in the background or a SatelliteCharacter to Brit and Tiff, but in "The Price of Love" she plays a major role as Sheldon's fake date.
* EvilRedhead: She's a cruel bully with red hair
* FutureLoser: In 20 years she's shown to marry (and have a son with) JerkJock Sebastian, whom she needs to regularly bail out of jail.
* {{Greed}}: She extorts money from Sheldon after he offers to pay her to date him.
* MyNaymeIs: "It's pronounced Teresa!". Only the Crust cousins seem to get it.
* SpoiledBrat: No better than her two friends, especially in "The Price of Love".

!!Other Characters

->Voiced by: Creator/ThoraBirch

A citizen of Cluster Prime who seems wholly non-confrontational. [[spoiler:Eventually revealed to be the princess of Cluster Prime]].
* BladeBelowTheShoulder: She gains the ability to grow one once she installs the chip that unlocks it.
* MadScientistsBeautifulDaughter: She's a robot from Cluster Prime, a race previously seen only as hostile. [[spoiler: She is also Queen Vexus' daughter, and becomes the queen after Vexus's regime is overthrown.]]
* PowerGivesYouWings: Dragonfly wings, in her case.
* SimilarSquad: Her circle of friends look just like Jenny's friends back home, with Vega being the counterpart to Jenny herself.

->Voiced by: Audrey Wasilewski

An alien girl with superpowers who met Jenny as part of a team. The team later disbanded, and Misty returned to Earth.
* {{Bifauxnen}}: One of the more (tom)boyish-looking girls on the show.
* CoolLoser: Like the rest of Team Teen and Jenny, she is a misfit but she is pretty good at her job.
* CurtainsMatchTheWindows: Purple hair and purple eyes.
* DestructiveSaviour: She doesn't care about any collateral damage she causes as long as she gets paid or has fun. She tries to use [[BusFullOfInnocents a schoolbus full of children]] to crush a monster.
* EvenEvilHasLovedOnes: Even when she becomes a selfish mercenary, Misty still considered Jenny her friend and was willing to help her out without expecting anything in return. When Jenny realizes how dangerous she is and they fight, Misty wins but can't bring herself to kill Jenny, [[IWasJustPassingThrough claiming it was because no one was paying her for it]].
* EvilCannotComprehendGood: She was absolutely confused by Jenny's remorse for [[SympathyForTheDevil scaring the Crust Cousins to tears]].
* EvilCounterpart: She ultimately ends up as one to Jenny: they're both superheroes that consider themselves outcasts, but Jenny's friends and family motivate her to [[ComesGreatResponsibility user her strength for good]] while Misty's detachment from almost everyone else leads her to abusing her power for personal gain and satisfaction.
* EvilFormerFriend: She was pretty much Jenny's best female friend. But Misty got more ruthless to the point she only thought of helping people if she could benefit from it. All to the point where Misty nearly kills Jenny in a fight where Jenny [[CurbStompBattle was clearly outmatched]] [[WorfHadTheFlu (due to a couple of factors)]]. The only thing that stopped Misty and snapped her somewhat back was Jenny [[TearJerker still pleading that she still saw her as a friend]].
* {{Expy}}: Since Team Teen is an homage to ''WesternAnimation/TeenTitans'', she eerily resembles Raven.
* HumanAliens: She's an alien, but pretty much looks like a human.
* OnlyInItForTheMoney: By "Mist Opportunities", she attempts to charge money for her services and is callously unashamed in leaving people to their fate if there's no money in saving them. After giving a brutal beating to Jenny at the end of the episode, she even claims that the only reason she's sparing Jenny is because no one is paying her to finish her off.
* ParentalAbandonment: Her and the rest of the Teen Team are apparently all orphans. She tries to justify charging for her services to Jenny by contemptuously pointing out [[FreudianExcuse she doesn't have any parents to provide for her.]]
* PerkyGoth: She has a gothic appearance and has an upbeat, care-free demeanor.
* PunchClockHero: In "Mist Opportunities", she's decided to help people on a pay-only basis, and left Tremorton to be destroyed by a monster when they wouldn't pay her for what she'd already done.
* SuddenSequelHeelSyndrome: When Misty was part of Team Teen, she did superheroics without any expected reward, albeit [[NotInThisForYourRevolution seemingly because it was fun]] and [[SmugSuper with a condescending attitude toward "normies"]]. After coming back to Earth and enrolling at Tremorton High, she shows she can be a rather vindictive bully. After she's expelled, then moves back to Tremorton, Misty is basically just a [[OnlyInItForTheMoney money-grubbing]] mercenary who'll endanger civilians to get her job done faster.
* SuperpowerLottery: Let's see: she's a skilled [[SupernaturalMartialArts martial artist]], has SuperStrength, can [[{{Flight}} fly]], turn into [[SuperSmoke mist]], shoot [[EyeBeams laser beams from her eyes]], and [[MindManipulation control peoples' minds]].
* SuperSmoke: Her most often used superpower is her ability to turn into a cloud of purple mist at will (hence her name).
* TookALevelInJerkass: In "Teenage Mutant Ninja Troubles" and "Mist Opportunities", she becomes more callous, self-centered, and materialistic.
* YouGottaHaveBlueHair: Misty has purple hair.

[[folder:Melody Locus]]
-->Voiced by Creator/SandyFox

The gentle daughter of a MadScientist named Dr. Locust. She has a crush on Brad, but [[spoiler:is secretly a highly advanced android.]]
* BigDamnKiss: Gives this to Brad to ease him up about her being a robot. It works.
* CreepyBlueEyes: To add to the creepiness, her ''pupils'' are blue while her iris is black.
* GoodAllAlong: Jenny believes her to be evil [[spoiler:due to being a creation of Dr. Locus]]. Turns out she ran away from her father and just wants to make friends and fit in as a teenager, like Jenny.
* GoodThingYouCanHeal: She is less durable than Jenny but makes up for it by fixing herself instantly.
* HairOfGoldHeartOfGold: She has blonde hair to match her sunny personality.
* IJustWantToBeNormal: States this during her fight with Jenny.
* MadScientistsBeautifulDaughter: As the daughter of the wicked Dr. Locust.
* RidiculouslyHumanRobot: Especially when compared to Jenny. She has skin and facial features that are indistinguishable from a human.
* ThePresentsWereNeverFromSanta: Brad appears to unassistedly carry Jenny (a 600-pound robot) and rescue her from Dr. Locus's lair. It's revealed that Melody was secretly helping him that time.

[[folder: Dr. Phineas Mogg]]
--> Voiced by Neil Ross

A scientist who is the rival of Nora Wakeman, and creator of YK-9 (AKA Kenny).
* AmazingTechnicolorPopulation: He has green skin.
* GreenAndMean: He's a jerk.
* LoveObstructingParents: Drags Kenny away from his date with Jenny, since he doesn't approve his son being in a relationship with his rival's creation. Although at this point, Jenny was only dating Kenny for popularity, not because she loved him.
* MadScientist: Like Nora.
* PetTheDog: In "Agent 00' Sheldon" he genuinely seems concerned his son is missing.
* PunnyName: His name is likely a play on Phileas Fogg, the protagonist of ''Literature/AroundTheWorldInEightyDays''.
* ShoddyKnockoffProduct: Most of his inventions are copies of Nora's, including his son.
* SitcomArchNemesis: His relationship to Nora.
* YouGottaHaveBlueHair: His hair is also green.

[[folder: YK-9/Kenny]]
--> Voiced by Creator/JamesArnoldTaylor

Phineas Mogg's son who's a male knockoff of Jenny. They briefly dated, but she was no longer interested once she realized he was part-dog.
* AmicableExes: Though they never broke up on screen, it's safe to say he's no longer in a relationship with Jenny. Despite this, the next time they meet they appear to be on good terms.
* AnimalJingoism: Immediately chases Sheldon once he dresses up as a cat.
* DatingWhatDaddyHates: Continues to date Jenny even though both their parents disprove of it.
* MyInstinctsAreShowing: He displays dog like behavior, such as licking, barking, and chasing cats.
* NiceGuy: He's rather chill and treats Jenny kindly.
* MundaneUtility: He's able to use his robot body to cook pizzas. It gets him really popular with the other kids.
* PunnyName: The K-9 part of his name reveals his true nature.
* RobotHair: It appears to be a normal haircut, but it can look like dog ears.
* SpearCounterpart: He was created to be a male version of Jenny. Who's also part-dog.
* SuperSenses: Being part-dog he has enhanced hearing and smell.

[[folder: Wisteria Wakeman]]
--> Voiced by Candi Milo

Dr. Nora Wakeman's sister who is a flower child and focuses on the natural world and biological in contrast with her mechanical-based genius sister.
* [[BigLittleBrother Big Little Sister]]: Maybe. It's not known whether Wisteria is the older or younger one. However, she is definitely taller than Nora is and Wisteria retained her hair color while Nora's is white. On the other hand, in the family album, a teenage Wisteria is shown right after a picture of seeing Nora in the second grade.
* GranolaGirl: One of the things that set her apart from her sister, Nora.
* GreenThumb: She did end up creating Glenn Wakeman, a swamp monster-like entity who can manipulate plants. She also snapped her finger to cause a plant to grow as she stepped off her wagon.
* HereWeGoAgain: Despite having patched things up in their episode and gained an appreciation of family, they start bickering at the end of the episode, to the great annoyance of Jenny and Glenn.
* NotSoDifferent: Despite their different approaches, both are pretty stubborn in their approach, not to mention they're both single women who used very unorthodox means in their fields to create life (Nora and robotics with Jenny and Wisteria and nature with Glenn.)
* TrulySingleParent: Much like her sister, she created her own child, who, much like Jenny, is not human.

[[folder:Glenn Wakeman]]
-->Voiced by: Jeff Doucette

A strange little swamp-monster like guy, he was created by Wisteria Wakeman and treated like her son. This makes him Nora's nephew and Jenny's cousin.
* {{Acrofatic}}: He's plump but can put up a fight if he chooses to.
* BlackBeadEyes: Has these instead of the regular [[PieEyed pac-man eyes]].
* CombatTentacles: Uses vines as these.
* GreenThumb: During his (fake) fight with Jenny, he is able to shapeshift his various limbs and parts of himself into different plants like vines and cacti.
* NiceGuy: He is a very sweet and cheerful fellow and unlike their mothers, he gets along very well with Jenny.
* PlantPerson: A big contrast with his metallic robot cousin, Jenny.
* SimpletonVoice: Speaks this way, likely to contrast with the high-tech Jenny.
