!!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" 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 desires to live the life of a normal teenager and often makes this desire quite apparent to her friends and creator.

* ActionGirl
* {{Adorkable}}: When she gets acquainted with the real world for the first time.
* AllOfTheOtherReindeer: No matter what she does, she will always somehow end back up as the school freak.
* BadassAdorable and CuteBruiser
* BalloonBelly: She inflated more than once, despite being made of metal.
* BareYourMidriff: Her chassis design is meant to mimic this, complete with a large exposed screw for a "belly button".
* BewareTheNiceOnes: Her temper is incredibly human, all things considered. Combine that with a HyperspaceArsenal, and you get literally-explosive anger.
* BrattyTeenageDaughter: To Nora sometimes.
* ComicallyMissingThePoint: She takes Tucker's literal advice and eats a bunch of cotton balls to experience feels.
* 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.
* [[CuteMachines Cute Machine]]
* DeadpanSnarker: Started developing into this by season two.
* DoAnythingRobot: Her arsenal is downright {{Hammerspace}}y.
* [[DoesNotKnowHisOwnStrength Does Not Know Her Own Strength]]: Sometimes, depending on if it's [[RuleOfFunny funny]] at the moment.
* FemBot
* GenkiGirl
* GirlishPigtails
* {{The Hero}}ine
* 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[=/=]NiceGirl: She often shifts between these, 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.
* MagicSkirt: Justified, that skirt's made out of metal.
* PinocchioSyndrome: Averted - she's perfectly fine with being a robot, but wants acceptance and assimilation... which sometimes means playing the trope straight.
* RedHeadedHeroine: Once had red body paint, and her makeshift human form is a redhead.
* RidiculouslyHumanRobot
* RobotGirl
* RobotHair: She sports a pair of metal pigtails. They house two of her jet thrusters.
* StatuesqueStunner: She's 6 1/2 feet tall (though this seems to include her hair) and really cute to boot.
* 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]]
* [[SurprisinglyGoodEnglish Surprisingly Good Japanese]]: Helped by the fact that her VA Creator/JaniceKawaye is a Japanese-American who speaks the language fluently.
* TelescopingRobot: She provides the trope picture.
* WakeUpGoToSchoolSaveTheWorld
* 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 forced to be in Kindergarden for the majority of the episode "I was a Preschool Dropout".
* YouGottaHaveBlueHair: Most of her ''body'' is baby-blue metal, jet-powered pigtails included.

[[DependingOnTheWriter It depends on the writer.]]

XJ-9's prototypes and "sisters".

* BabyLanguage: XJ-1.
* [[BigLittleBrother Big Little Sister]]: XJ-8.
* BreakOutTheMuseumPiece[=/=]MisfitMobilizationMoment: Once, after Jenny got captured by the Cluster. 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.
* CrossdressingVoices: XJ-8.
* CuteClumsyGirl: XJ-3.
* CyberCyclops: XJ-3 and XJ-6.
* TheEeyore: XJ-7.

* HiccupHijinks: XJ-2 again.
* MoodSwinger: XJ-6.
* MotorMouth: XJ-5.
* NeatFreak: XJ-4.

!!Queen Vexus
->Voiced by: Eartha Kitt, Creator/CreeSummer ("Around The World in 50 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
* AnimalMotifs: She resembles an insect of some sort.
* BigBad: Vexus is this for the entire show.
* {{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: Genuinely cares about her people. Jenny even exploits this at one point, telling her that if she doesn't surrender, she will destroy one of Vexus' 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.)
* GodSaveUsFromTheQueen: Cluster Prime's residents are actually good-natured, but they are forced to obey Vexus or be destroyed.
* HellishPupils
* IneffectualSympatheticVillain: Starts off as a huge threat, but becomes an easily dispatched threat later on. This really gets hammered home, though, when [[spoiler: she eventually loses her dictatorship over Cluster Prime]].
* 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
* 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.


A large green robot from the Cluster who seems to have ties to its military division.

* 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.
* IJustWantToHaveFriends: Hinted at. He perks up quite a lot when he's complimented by the humans, and he has to remind his minions to laugh with him after he makes a short speech.
* IneffectualSympatheticVillain: Shares this trope with Vexus and Krackus in Season 3.
* LargeHam: When making his entrance.
* PaperThinDisguise: He puts on a wig and tries to pass of 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, ''he falls for the disguise himself''.
* SuperheroMovieVillainsDie: [[spoiler: In the BigDamnMovie, Smytus' last resort is a self-destruct mechanism he had installed on his forearm.]]


A senile, older 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.

* BunglingInventor: Most of his inventions fall apart after one use.
* EvilOldFolks: He seems mostly harmless, though.
* IneffectualSympatheticVillain: Shares this trope with Vexus and Smytus in Season 3.
* InformedAbility: Inverted. 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.
* MiniatureSeniorCitizens: He's the shortest member of the Cluster seen before the BigDamnMovie.

->Voiced by: Creator/TaraStrong

* WindUpKey: It's Powered by Watch Spring and a wind-up key.

[[folder: Other Characters]]

->Voiced by: Audrey Wasilewski

An alien girl with superpowers who met Jenny as part of a team.

* [[EvenEvilHasStandards Even Mercs Have Standards]]: Even though she only does hero work for money and sees no problem with meditating while a KillerRabbit destroys the town, she was clearly disgusted that her former teammates lazed around and actually bet against Jenny as she fought against a [[ItMakesSenseInContext Giant Monstrous Frog]].
* [[EvilCannotComprehendGood Mercenaries Can't Comprehend Heroics]]: She was absolutely confused by Jenny's remorse for [[SympathyfortheDevil scaring the Krust Cousins to tears]].
* 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]]. The only thing that stopped Misty and snapped her somewhat back was Jenny [[TearJerker still pleading that she still saw her as a friend]].
* MoralityChain: Arguably Jenny.
* PunchClockHero: In "Mist Opportunities".
* SuperpowerLottery: Let's see: she's a skilled [[SupernaturalMartialArts martial artist]], has SuperStrength, can [[FlyingBrick 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).

The antagonists of Jenny's life in high school, they seek to humiliate her at every turn.

* 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.
* TheQuisling: Sided with the Cluster after they invaded Earth in "Escape from Cluster Prime".
* TooDumbToLive: More than one of their schemes have terribly backfired.
