    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: Janice Kawaye

The main protagonist and the "16-year-old robot" (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.

  • Action Girl: A ridiculously powerful crime-fighting robot.
  • Adorkable: When she gets acquainted with the real world for the first time.
  • The Ageless: 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.
  • Ain't Too Proud to Beg: Typically to her mother when she don't get her way.
  • All of the Other Reindeer: No matter what she does, she will always somehow end back up as the school freak.
  • Animesque: Her character design, just look at her!
  • Artificial Family Member: Even though Nora Wakeman created Jenny to protect the Earth, she was still treated like a daughter.
  • Badass Adorable: A One-Man Army shaped like a cute robot girl.
  • Balloon Belly: She has inflated more than once, despite being made of metal.
  • Bare Your Midriff: 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.
  • Beware the Nice Ones: Her temper is incredibly human, all things considered. Combine that with a Hyperspace Arsenal, and you get literally-explosive anger.
  • Big Sister Instinct: Jenny is rather protective of Tuck, and generally treats him like her was her little brother. His screaming even helped her when Fighting from the Inside.
  • 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.
  • Blue Is Heroic: Her body is white with blue paint on the parts that resemble hair and clothing.
  • Blush Stickers: When she blushes, she displays blue-colored ones.
  • Born as an Adult: 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.
  • Bratty Teenage Daughter: She sometimes acts like a disobedient teenage delinquent to Dr. Wakeman.
  • Butt-Monkey: 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).
  • Catch-Phrase: Crikey!
  • Cool Loser: It's hinted that if the school weren't under the tyrannical reign of two Alpha Bitches, Jenny wouldn't be a reject at all.
  • Curtains Match the Window: Her hair and outfit colors match.
  • Cute Bruiser: Built like a teenage girl and a super robot that regularly pummels monsters into the crowd.
  • Cute Machine: Just look at her, she's a total sweetie!
  • Deadpan Snarker: Started developing into sardonic banter by season two.
  • Demonization: Subverted In-Universe; Queen Vexus of Cluster Prime demonizes XJ9, presenting her like an Always Chaotic Evil, 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, heroic robot who wants to help and protect others. 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 Hidden in Plain Sight.
  • Dented Iron: She may be tough but she has her limits. Many times she gets beaten up to the point where she can hardly fight.
  • Destructive Saviour: Often causes buildings to get destroyed she fights monsters.
  • Ditzy Genius: A highly advanced and intelligent combat android. But she's pretty clueless and naïve when it comes to mingling with non-robotic teens.
  • Do-Anything Robot: Her arsenal is downright Hammerspacey.
  • Does Not Know Her Own Strength: 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.
  • Early Installment Character-Design Difference: In the original Oh Yeah! Cartoons pilot short, her hands were the same coloring as her hair and "clothes", she had lips, and her skirt had rivets on the bottom.
  • Fem Bot: She's a female robot built with a feminine shape.
  • Genki Girl: She's quite excitable and with a positive attitude.
  • Girlish Pigtails: She has 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.
  • Girly Girl with a Tomboy Streak: She's has a love for clothing, pretty boys and shopping, and has an overall feminine demeanor, but she's also a proud Action Girl loaded with weapons whose friends are mostly male.
  • The Heroine: The series revolves around Jenny who was created by her mother, Dr. Nora to protect Earth.
  • Hero with Bad Publicity: Despite saving the world multiple times, the citizens of Tremorton still treats her like garbage.
  • Held Back in School: Jenny is sent to kindergarten on one occasion because she is technically only 5 years old.
  • Huge Schoolgirl: She's stated to be 6' 6".
  • I Just Want to Be Normal: Combined with I Just Want to Have Friends: Being a superpowered robot wouldn't be so hard for her if there were more bots as advanced as her.
  • Jerk with a Heart of Gold: She often shifts between this and Nice Girl, depending on whether the episode is making liberal use of Surrounded by Idiots.
  • Jet Pack: 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.
  • Light Is Good: A white robot and The Heroine.
  • Lightning Bruiser: She possesses super strength and speed.
  • Loves My Alter Ego: Jenny just considers Sheldon her friend, but falls in love with Silver Shell almost immediately (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.
  • Magical Girlfriend: The components of the fantasy are all there; Sheldon, the Nerd Loser Protagonist, falls in love with the Super Heroine Fembot who saves him from bullies, and becomes her Dogged Nice Guy. Too bad she's not interested (although Word of God says that she would have become his girlfriend if the series had continued).
  • Magic Skirt: Justified, as that "skirt" is made out of metal and is actually her pelvis.
  • Meaningful Rename: 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 and Japanese.
  • Pinocchio Syndrome: Averted - she's perfectly fine with being a robot, but wants acceptance and assimilation... which sometimes means playing the trope straight.
  • Platonic Life-Partners: 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.
  • Ridiculously Human Robot: Jenny thinks, emotes, cries, sleeps, and eventually dreams like a human. About the only humanlike thing she can't do is eat anything besides oil.
  • Robot Girl: An American twist on the trope: Jenny is less interested in saving the world than hanging out with high school kids.
  • Robot Hair: She sports a pair of metal pigtails. They house two of her jet thrusters.
  • Single Woman Seeks Good Man: 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 Word of God after the series' cancellation.
  • Sliding Scale of Robot Intelligence: Average Joe: Emotionally, she's basically like a human teenager—which is to say she can be very mature or very childish depending on the situation. Intellectually, it seems to vary by the episode whether she's a lot smarter than most humans, or basically just like a human with a built-in calculator.
  • She Cleans Up Nicely: 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?
  • Slapstick Knows No Gender: She tends to suffer more injuries than the rest of the cast.
  • Statuesque Stunner: 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.
  • Super Strength: "The strength of a million-and-seventy men," if the theme song is to be taken literally. note 
  • Telescoping Robot: She provides the trope picture.
  • Wake Up, Go to School, Save the World: Pretty much her daily life, though the school bit is new.
  • Weaksauce Weakness: Water tends to fry her circuits or rust her skin.
  • What the Hell, Hero?: 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 trying to kill Melody, who she mistakenly thinks is a villain.
  • Younger than She Looks: 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".

    Brad Carbunkle
Voiced by: Melissa Denton (Oh Yeah! Cartoons pilot), Chad Doreck

Jenny's best friend and next-door neighbor.

  • Action Survivor: 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.
  • Anime Hair: He has three large spikes in his hair. He uses a lot of hair gel to get it that way.
  • Badass Normal: No super powers to speak of, but still occasionally manages to be useful in battle.
  • Camp Straight: Brad is rather metrosexual, but shows exclusive (and frequent) interest in women.
  • Casanova Wannabe: Brad frequently insists he's irresistible to the ladies, which always causes any girl present (but Jenny) to turn their nose up at him.
  • Chick Magnet: While Brad's game with human girls is pretty dire, he seems to have no problem attracting the attention of aliens and robots. Pretty much none of it is wanted.
  • Cool Loser: Brad has a fairly cool demeanor and a decent fashion sense, but is implied to be pretty low on the social ladder.
  • Crouching Moron, Hidden Badass: 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.
  • Distressed Dude: His gung-ho attitude frequently results in him needing to be rescued.
  • The Face: 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 Jenny can't.
  • Fearless Fool: Tends to leap headfirst into action despite almost always being way out of his depth.
  • Fiery Redhead: 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 would rather be a normal teenager, Brad is an ordinary guy who is extremely self-assured and desperately wants to be anything but a normal teenager.
  • Glory Seeker: 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.
  • I Just Want to Be Special: 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.
  • Interspecies Romance: Brad seems quite prone to this, considering his short relationship with Melody and his implied relationship with Misty.
  • The Load: 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.
  • Muggle Best Friend: He's an ordinary human who is best friends with a super-fighting robot.
  • Nice Guy: Brad is typically a very friendly, upbeat person.
  • The Not-Love Interest: He's Jenny's best friend and usual foil, but their relationship is entirely platonic.
  • Platonic Life-Partners: 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.
  • Redheads Are Uncool: Isn't too popular at his school.
  • Ridiculously Average Guy: Though he wishes to be more.
  • Small Name, Big Ego: 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.
  • Took a Level in Badass: After training in the Skyway Patrol, he becomes more consistently reliable during action sequences.
  • Unfazed Everyman: Generally handles supernatural encounters with a combination of neutrality and enthusiasm.
  • Weirdness Magnet: The supernatural and the extraterrestrial seem to be naturally drawn towards him.

    Tuck Carbunkle
Voiced by: Audrey Wasilewski

Brad's little brother.

  • Annoying Younger Sibling: Tuck can sometimes be annoying, mostly because he's such a scream 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".
  • Badass Adorable: He knows almost as much as Dr. Wakeman about robots.
  • Cheerful Child: Tuck is very enthusiastic and smiles almost constantly.
  • Distressed Dude: Even more than his brother.
  • Jerk with a Heart of Gold: Depending on the Writer, 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.
  • Kid-Appeal Character: Despite being a kids' show, the main cast is almost entirely teenagers, so Tuck fills in the much-needed role of a kid character.
  • Karma Houdini: In several episodes his selfishness causes destruction and pain for the main heroes, but he gets off relatively free.
  • Kids Are Cruel: His treatment of Jenny, Sheldon, and Brad can get downright brutal.
  • Lack of Empathy: One of his major flaws, Depending on the Writer. 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.
  • Large Ham: He's got quite a pair of lungs for a little guy and puts them to use.
  • Lovable Coward: He's the most likely to start running and screaming in any situation.
  • Only Sane Man: Slides in and out of this if the situation calls. Conversely, in a few episodes he's a pushy jerk.
  • Taking Advantage of Generosity: 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. This generally doesn't end well for him.
  • Wholesome Crossdresser: 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.

    Dr. Nora Wakeman
Voiced by: Candi Milo

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.

  • Action Mom: When in danger, she shows no reluctance in fighting.
  • Amazingly Embarrassing Parent: Anytime Nora talks to a peer of Jenny besides Brad and Tuck, expect to her some embarrassing detail about Jenny's design or maintenance.
  • Cool Old Lady: She even fought Vexxus with her bare hands!
  • Defrosting Ice Queen: 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.
  • Gadgeteer Genius: She's built incredibly powerful Ridiculously Human Robots as well as other machines.
  • Genki Girl: She comes off as a lively and excitable woman. No surprise where Jenny gets it from.
  • Early Installment Character-Design Difference: She had a different hairstyle and her clothes were completely white in the pilot short on Oh Yeah! Cartoons.
  • Einstein Hair: Her hair is white, spiky and messy
  • Gag Nose: While it isn't pointed out often, in The Movie Sheldon calls her a "birdnose" and later she uses it to poke Vexus's eye.
  • Mad Scientist: One of the saner ones, but some of her inventions and experiments seem to serve no clear purpose.
  • Mama Bear: 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 Retired Badass
  • Meddling Parents: One episode had her remove Jenny's ability to hang-up on her
  • Motherly Scientist: Jenny calls her "mom" and Dr. Wakeman certainly does view her as her daughter.
  • Never Mess with Granny: She used to be part of the Skyway Patrol prior to the series. Even in present-day she's far from any definition of "weak".
  • Older Than They Look: 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.
  • The Professor: She created Jenny and tends to provide her with upgrades and gadgets of her own design to help Jenny take on tough opponents.
  • Sibling Yin-Yang: 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 Plant Person son, Glenn.
  • Shipper on Deck: 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.
  • Truly Single Parent: 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.

    Sheldon Lee/Silver Shell
Click here  to see Silver Shell

Voiced by: Quinton Flynn

Jenny's self-proclaimed romantic admirer.

  • Abhorrent Admirer: Towards Jenny at first, but mellows out of his stalking in later episodes and she starts to enjoy his company.
  • Ace Pilot: 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.
  • Agent Peacock: When he joins the secret agency, his codename is "Baron Von Fashionista III".
  • Ambiguously Bi: In one episode he has a conversation with Jenny discussing which members of a Boy Band is the cutest.
  • Asian and Nerdy: 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.
  • Awesome, but Impractical: 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. Yeah.
  • Big Brother Instinct: 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.
  • Butt-Monkey: Suffers quite a bit over the course of the series.
  • Chivalrous Pervert: 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.
  • Clark Kenting: 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.
  • Crouching Moron, Hidden Badass: 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) 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.
  • Distressed Dude: Though this becomes less frequent later on.
  • Dogged Nice Guy: Several times his sincere and friendly attitude have gotten Jenny's affection, only to lose it because of a misunderstanding or because Jenny found out something very unpleasant that he'd done recently.
  • Dude, Where's My Respect?: It's not that he can't ever get any respect, but he has to work much harder for it.
  • Forgotten Phlebotinum: 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.
  • Gadgeteer Genius: He's created functioning Power Armor, his own robots (though nothing as human-like as Nora's), new gadgets for Jenny to use, and a functioning time machine.
  • Hates My Secret Identity: 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.
  • Hero-Worshipper: A variant in that he's smitten with XJ-9 as well as seeing her as a role model.
  • In Touch with His Feminine Side: Sheldon's not exactly a masculine type, and he has interests in Fashion Magazines and Boy Bands.
  • Interspecies Romance: Sheldon's crush on Jenny.
  • Large Ham: As the Silver Shell, he has melodramatic and hammy dialogue to play up his being a superhero.
  • Older Than They Look: The events of "Good Old Sheldon" ended with him physically 15 years old, but 105 chronologically and mentally—and he remembers all of it.
  • Only Sane Man: 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.
  • Rescue Romance: 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 XJ 9 blueprints he stole from Nora. It works.
  • Single-Target Sexuality: Jenny is the only person he's attracted to.
  • Stalker Shrine: He has an unsettlingly large colletion of pictures of Jenny in his closet and his locker.
  • Stalker with a Crush: In his introduction episode he was definitively this, but in later episodes he is more friendly and helpful towards Jenny.
  • Strong, but Unskilled: As the Silver Shell his fighting style is rather sloppy but the suit is strong enough for him to last.
  • Throw the Dog a Bone: 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 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.
  • Took a Level in Badass: 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.
  • Undying Loyalty: 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.
  • What Does She See in Him?: 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.
  • Yank the Dog's Chain: 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.

    XJ- 1 through XJ- 8
Clockwise, beginning center: XJ-4. XJ-6, XJ-5, XJ-1, XJ-8, XJ-7, XJ-2, XJ-3
Voiced by: Janice Kawaye (XJ-1), Kath Soucie (XJ-2, XJ-3, XJ-4 and XJ-5), Candi Milo (XJ-6), Audrey Wasilewski (XJ-7 and XJ-8)

XJ-9's prototypes and "sisters".

  • Big Little Sister: XJ-8 is much larger than Jenny despite being considered her younger sister. She is technically also older (which would make XJ-1 the Little Big Sister), though Jenny seems to have spent the most time online.
  • Break Out the Museum Piece: 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 telescoping armor Jenny does.
  • Combining Mecha: 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".
  • Cute Clumsy Girl: XJ-3 constantly trips and falls apart.
  • Cyber Cyclops: XJ-3 has one physical eye that sits on top of her body while XJ-6 has a computer display face that shows one eye.
  • The Eeyore: XJ-7 is constantly depressed, even lamenting that she couldn't destroy herself properly.
  • Flawed Prototype: All of them. Unlike most examples of the trope, though, they are clearly functional testbeds that do well within the parameters of their design.
  • Frickin' Laser Beams: XJ-2 is basically a laser gun with legs and eyes.
  • Green-Eyed Monster: 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.
  • Hiccup Hijinks: XJ-2 constantly hiccups, causing her to misfire.
  • Machine Monotone: XJ-8 speaks like this, though the tone changes depending on the episode.
  • Motor Mouth: 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.
  • Neat Freak: XJ-4 compulsively cleans everything she sees.
  • Ridiculously Human Robots: The XJ sisters appear to be gradually working towards this. May also be why XJ-8 isn't the last in the line.
  • Sliding Scale of Robot Intelligence: 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.
  • Super Prototype: 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 so terrible at talking to people still makes her a Flawed Prototype even in terms of being a superhero, as she, for instance, thought children breaking a pinata were committing a crime.


    Queen Vexus
Voiced by: Eartha Kitt, Cree Summer ("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.

  • Arch-Enemy: Vexus to Jenny, and vice-versa. Vexus isn't even happy with conquering Earth unless Jenny is there to see it.
  • Attention Whore: Has devolved into this by season 3, where she's overjoyed to be worshiped by the entire school ever since she lost her planet.
  • Bad Samaritan: She claims to be a liberator of machines, though her definition of "liberation" is merely a sugar-coated "assimilation into our collective".
  • Be Careful What You Wish For: 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!
  • Bee People: She resembles an insect of some sort.
  • Big Bad: Vexus is the main villain for the entire show.
  • Bitch in Sheep's Clothing: 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.
  • Break the Haughty: She eventually loses her dictatorship over Cluster Prime, reducing her to a madwoman living on a garbage planet and talking to the creatures crawling around it. She's mostly back to normal by the end of the season and menacing Jenny as usual, though without her empire behind her, she's significantly less of a threat.
  • Broken Pedestal: 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 even to the point of losing her status as Queen, she still insists on attacking Jenny any chance she gets.
  • Even Evil Has Loved Ones: 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!
  • Evil Matriarch: Subverted. She may be evil and the Big Bad of the show, but she still loves Vega (almost to the point of being overprotective, even.)
  • Fantastic Racism: Doesn't much like humans, even calling them derogatory names like "flesh wearers".
  • Faux Affably Evil: She is usually polite to Jenny, even while trying to destroy her or assimilate her into the Cluster.
  • Galactic Conqueror: Being the leader of an interstellar robot extremist empire bent on enslaving the human race, she certainly qualifies.
  • God Save Us from the Queen!: Cluster Prime's residents are actually good-natured, but they are forced to obey Vexus or be destroyed.
  • Hive Queen: If her queen bee motif didn't give it away, she's the head of a collective of bug themed robots.
  • How the Mighty Have Fallen: 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.
  • Join or Die: Her general philosophy when it comes to assimilating robots into the Cluster.
  • Laser-Guided Karma: 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.
  • Manipulative Bitch: 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.
  • Not So Different: For someone who despises humanity and boasts about robot superiority, she herself possesses some of their worst traits, being a dictator and all.
  • Overarching Villain: She is present for the entire show, appearing every season and always hatching some scheme to enslave humanity.
  • Revenge Before Reason: 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.
  • Sanity Slippage: 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".
  • Take Over the World: Pretty much her entire plot in a nutshell.
  • Totally Radical: She would have blended in while she was destroying Jenny if she only realized that The Roaring '20s was over for almost a century now.
  • Tsurime Eyes: Her eyes are slanted upwards.
  • Villainous Breakdown: 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.
  • We Can Rule Together: 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.

    Commander Smytus
Voiced by: Steve Blum

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

  • Badass Baritone: Comes with being voiced by Steve Blum.
  • Badass Boast:
    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!
  • Bad Boss: His answer to one incompetent minion causing him to lose the Pip crystals? Throw his entire crew out the airlock.
  • Big Creepy-Crawlies: Resembles an anthropomorphic rhinoceros beetle
  • Broke Your Arm Punching Out Cthulhu: Even after he 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.
  • The Brute: 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.
  • Card-Carrying Villain: If his "DESTROYER OF WORLDS!" speech is anything to go by, he really enjoys being a villain.
  • The Dragon: Smytus serves as one to Vexus.
  • Dragon Their Feet: After Vexus is defeated in the Escape From Cluster Prime special, Smytus is still threatening to destroy Earth. He doesn't get very far.
  • Dude, Where's My Respect?: In his first appearance, he laments that Vexus gives him demeaning nicknames.
  • Evil Gloating: Thanks to his ego, he will engage in this any chance he gets.
  • Evil Is Hammy: As demonstrated on Incoming Ham below, he has the subtlety of a sledgehammer to the face.
  • Evil Laugh: Goes hand in hand with his Large Ham. He's very fond of these.
  • Evil Sounds Deep: Not as deep as some of Blum's other roles, but still fairly low-pitched.
  • Fantastic Racism: Like the rest of the Cluster, he doesn't hold "fleshbags" in very high regard.
  • General Ripper: The leader of the Cluster's armies and not a villain to be taken lightly.
  • Half the Man He Used to Be: The explosion in Escape From Cluster Prime reduces him to a torso forced to walk on makeshift legs, cobbled together from junk.
  • Hyper-Competent Sidekick: 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.
  • Incoming Ham: "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 Dramatic Thunder)
  • Ineffectual Sympathetic Villain: In season 3, he's left as a pathetic wreck who mostly just wants to get his legs back.
  • I Just Want to Have Friends: Played with. 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.
  • Large and in Charge: He's bigger than most of the established Cluster villains, and is their military commander.
  • Not Quite Dead: 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.
  • Paper-Thin Disguise: 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, he falls for the disguise himself.
  • Self-Destruct Mechanism: He has one literally stored in his sleeve. Of course, it comes with a ten second countdown, as well.
  • Small Name, Big Ego: 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!
  • Smug Snake: He's a fairly capable villain, all things considered, but he vastly overestimated his abilities, which tends to be his undoing.
  • Sore Loser: 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.
  • Surrounded by Idiots: His opinion of the drones under his command.
  • Taking You with Me: Attempts to self-destruct and take as many humans with him as possible. It doesn't work quite the way he intended, 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!
  • Top-Heavy Guy: One of, if not the strongest of Vexus' minions.
  • Uncertain Doom: 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.
  • Villain Ball: He gives his self-destruct sequence a countdown, allowing Jenny enough time to throw his ship into orbit as it explodes. Woops.

Voiced by: Jim Ward

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.

  • Beware the Silly Ones: Like what Nora tells her daughter, "Don't underestimate him! Sooner or later he may invent something that actually works!"
  • Big Creepy-Crawlies: Bears a resemblance to a large beetle.
  • Bungling Inventor: Most of his inventions fall apart after one use.
  • Evil Genius: Is the brains of the Cluster, though his subordinates think otherwise.
  • Evil Old Folks: He seems mostly harmless, though.
  • Ineffectual Sympathetic Villain: Shares this trope with Smytus in Season 3.
  • Informed Flaw: He's treated as a joke by most characters, but all his appearances in the show has him use his inventions rather competently.
  • Miniature Senior Citizens: He's the shortest member of the Cluster seen before the Big Damn Movie.
  • Not-So-Harmless Villain: 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.
  • Only Sane Man: 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.
  • Robot Hair: Has a metal mustache that also functions as a mouth in imitation of a beetle's mandibles.
  • Uncertain Doom: 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: Tara Strong

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.


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.

  • A.I. Is a Crapshoot: During peacetime, it turned on human weapons, giving itself the mission to destroy all weapons on Earth.
  • Badass Baritone: A quality that often comes with being voiced by Kevin Michael Richardson, of course.
  • Cain and Abel: 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.
  • Destructive Saviour: Armagedroid, who was built for the purpose of eliminating dangerous weaponry. Something that proved to be dangerous in peacetime.
  • Evil Sounds Deep: Courtesy of Kevin Michael Richardson.
  • Killed Off for Real: In his second appearance he self destructs after realizing he's a weapon.
  • Knight of Cerebus: Definitely not one of the more comical villains. He almost killed Jenny in their first battle!
  • Knight Templar: Wants to make the world a safer a bad way that is.
  • Humongous Mecha: Taller than most of the buildings in Tremorton.
  • Red Eyes, Take Warning: Huge red ones.
  • Villain Team-Up: Was later somehow rebuilt by Killgore.

    The Space Bikers
Clockwise, beginning left: Olga, Tammy, Letta, Lenny, and Sludge
Voiced by: Grey DeLisle (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.

  • Abhorrent Admirer: 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.
  • All Bikers Are Hells Angels: They're first introduced as a gang of thugs who spend their lives partying and wreaking havoc in orderly places, but 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.
  • Bare Your Midriff: Olga and Sludge wear clothes that leave their midsections exposed.
  • Biker Babe: With the exception of Lenny, they're all female bikers. Tammy stands out in particular.
  • Butt-Monkey: Lenny tends to be regularly roughed up by Letta. And the bikers as a whole always suffer when they mess with Jenny.
  • Fish People: Their species sorta resembles the Creature from the Black Lagoon.
  • Green and Mean: They have green skin.
  • Happiness in Slavery: 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.
  • Hartman Hips: Tammy has very large hips.
  • Huge Girl, Tiny Guy: Lenny is minuscule compared to all of the other Bikers, especially his wife Letta
  • Laser-Guided Karma: 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.
  • Non-Mammal Mammaries: Despite being fish people, Letta, Sludge, and Tammy have breasts. Seemingly averted for Olga, though she appears to wear a crop top.
  • The Noseless: All of them except Tammy lack noses. Tammy turns out to have a nose when her full face is revealed in "Ball and Chain".
  • The One Guy: Lenny is the only male in the group.
  • Punch-Clock Villain: 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.
  • Quirky Miniboss Squad: 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.

    Dr. Locus
Voiced by: Grant Albrect

An evil mad scientist who is the father and creator of Melody.

  • The Bad Guy Wins: Killing the heroes aside, Dr. Locus successfully accomplishes his objective in "Bradventure" by copying Jenny's abilities and installing them into Melody.
  • Bald of Evil: He has no hair on his head.
  • Beard of Evil: He has a scruffy white beard.
  • Bitch in Sheep's Clothing: 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
  • Bond Villain Stupidity: Averts this by refusing to tell Brad his evil plan, though later he forgets he didn't.
  • Creepy Blue Eyes: One thing noticeable is that his eyes are blue instead of black like most other characters.
  • Eaten Alive: Gets devoured by Dr. Wakeman's garbage disposal machine in "Turncoats".
  • Evil Is Hammy: He enjoys gloating this way.
  • Evil Counterpart: Like Nora Wakeman he's a Mad Scientist with a robot teenage daughter. Unlike Nora, he's doesn't treat his daughter with respect and is evil.
  • Evil Old Folks: He's pretty old.
  • Green-Eyed Monster: The reason he's angry with Nora is because his inventions were less popular.
  • Knight of Cerebus: 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.
  • Mad Scientist: He's an inventor with questionable sanity and morals, though he insists he isn't.
  • Pragmatic Villainy: 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.
  • Top-Heavy Guy: He has a large broad torso and legs that are basically nubs.
  • Unknown Rival: Dr. Wakeman had no idea he existed until he showed up in the last episode.

Tremorton High

    The Crust Cousins, Brit and Tiff
Brit (right) and Tiff (left).
Voiced by: Cree Summer (Tiff), Moira Quirk (Brit)

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

  • Alpha Bitch: They torment Jenny simply because a super-powered robot would otherwise be more popular than them.
  • Attention Whore: 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.
  • Ambiguously Brown: It's not stated what Brit's ethnic background is, though Indian makes the most sense, considering her English accent and Britain's past colonisation of India. She could also be South African for the same reason.
  • Bare Your Midriff: 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.
  • British Teeth: Downplayed by Brit, who simply has slightly goofy-looking buck teeth. One Grossup Closeup implies they're much worse than they look from a distance, though more crooked than dirty.
  • Bullying a Dragon: 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 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.
  • The Dividual: Syndividual; they look very different and have some contrasting personality traits, but are almost always together and acting in unison.
  • Eerie Pale-Skinned Brunette: Tiff, which contrasts with her Pretty Fly for a White Guy-style speech.
  • Even Evil Has Loved Ones: Brit and Tiff do seem to genuinely care about each other as cousins
  • Fat and Skinny: Tiff and Brit, respectively. Tiff is more curvy than fat, but she still greatly contrasts Brit physically.
  • The Fashionista: Both of them have impeccable dress sense, and are always seen wearing a new trendy outfit whenever they appear.
  • Future Loser: In "The Price of Love" we see that in 20 years Brit and Tiff will become poor and ugly.
  • Girly Girl with a Tomboy Streak: Downplayed with Brit. While she occasionally dresses in an androgynous style, she otherwise possesses the standard haughty queen bee personality, and frequently wears very feminine clothing.
  • Hartman Hips: Tiff sports a pair.
  • Heel–Face Door-Slam: 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.
  • Hoist by His Own Petard: More than one of their schemes have terribly backfired.
  • Lean and Mean: 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.
  • Mean Brit: Brit has the accent and the attitude, though one wonders if she's actually British or not.
  • Meaningful Name: Brit speaks with a British accent, and a "tiff" is a kind of petty squabble, which the two frequently instigate.
  • Noodle People: Brit is very tall and skinny, which stands out opposite the short and curvy Tiff.
  • Pretty Fly for a White Guy: 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.
  • Red Oni, Blue Oni: Brit is more soft-spoken, cold and manipulative while Tiff is more loud, brash and aggressive.
  • The Quisling: 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, they switch back just as quickly.
  • Spoiled Brats: 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.
  • Those Two Bad Guys: A pair of queen bees with a habit of tormenting Jenny Wakeman.
  • Unlimited Wardrobe: 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.

    Don Prima
Voiced by: Quinton Flynn

The most popular boy in school. Jenny used to have a crush on him.

  • The Casanova: Implied to have gone on brief dates with most girls in the school.
  • Jerk Jock: 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.
  • Meaningful Name: 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.
  • What Does She See in Him?: Thankfully Jenny seems to have lost interest in him after she sees he cared more for his shoes than her.
  • Wild Teen Party: He throws one in The Great Unwashed.

Voiced by: Candi Milo

The best friend of Brit and Tiff who's often seen accompanying them.

  • The Beard: As a part of Sheldon's Operation: Jealousy.
  • Berserk Button: When people pronounce the "p" in her name.
  • Beta Bitch: Seems to be next in the social status after Brit and Tiff
  • A Day in the Limelight: She's usually just in the background or a Satellite Character to Brit and Tiff, but in "The Price of Love" she plays a major role as Sheldon's fake date.
  • Evil Redhead: She's a cruel bully with red hair
  • Future Loser: In 20 years she's shown to marry (and have a son with) Jerk Jock 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.
  • My Nayme Is: "It's pronounced Teresa!". Only the Crust cousins seem to get it.
  • Spoiled Brat: No better than her two friends, especially in "The Price of Love".

  • Blade Below the Shoulder: She gains the ability to grow one once she installs the chip that unlocks it.
  • Mad Scientist's Beautiful Daughter: She's a robot from Cluster Prime, a race previously seen only as hostile. She is also Queen Vexus' daughter, and becomes the queen after Vexus's regime is overthrown.
  • Power Gives You Wings: Dragonfly wings, in her case.
  • Similar Squad: 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.

    Melody Locus
Voiced by Sandy Fox

The gentle daughter of a Mad Scientist named Dr. Locust. She has a crush on Brad, but is secretly a highly advanced android.

  • Big Damn Kiss: Gives this to Brad to ease him up about her being a robot. It works.
  • Creepy Blue Eyes: To add to the creepiness, her pupils are blue while her iris is black.
  • Good All Along: Jenny believes her to be evil 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.
  • Good Thing You Can Heal: She is less durable than Jenny but makes up for it by fixing herself instantly.
  • Hair of Gold, Heart of Gold: She has blonde hair to match her sunny personality.
  • I Just Want to Be Normal: States this during her fight with Jenny.
  • Mad Scientist's Beautiful Daughter: As the daughter of the wicked Dr. Locust.
  • Ridiculously Human Robot: Especially when compared to Jenny. She has skin and facial features that are indistinguishable from a human.
  • The Presents Were Never from Santa: 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.
  • The Rival: To Jenny.
  • Robotic Reveal: Jenny forces this on her during her date with Brad. He doesn't seem to mind.
  • Robot Girl: As revealed at the end of her first appearance, but Brad only learns about it in her next one.

     Dr. Phineas Mogg 
Voiced by Neil Ross

A scientist who is the rival of Nora Wakeman, and creator of YK-9 (AKA Kenny).


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.

  • Amicable Exes: 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.
  • Animal Jingoism: Immediately chases Sheldon once he dresses up as a cat.
  • Dating What Daddy Hates: Continues to date Jenny even though both their parents disprove of it.
  • My Instincts Are Showing: He displays dog like behavior, such as licking, barking, and chasing cats.
  • Nice Guy: He's rather chill and treats Jenny kindly.
  • Mundane Utility: He's able to use his robot body to cook pizzas. It gets him really popular with the other kids.
  • Punny Name: The K-9 part of his name reveals his true nature.
  • Robot Hair: It appears to be a normal haircut, but it can look like dog ears.
  • Spear Counterpart: He was created to be a male version of Jenny. Who's also part-dog.
  • Super Senses: Being part-dog he has enhanced hearing and smell.

     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.

  • 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.
  • Granola Girl: One of the things that set her apart from her sister, Nora.
  • Green Thumb: 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.
  • Here We Go Again!: 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.
  • Not So Different: 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.)
  • Truly Single Parent: Much like her sister, she created her own child, who, much like Jenny, is not human.

    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.
  • Black Bead Eyes: Has these instead of the regular pac-man eyes.
  • Combat Tentacles: Uses vines as these.
  • Green Thumb: 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.
  • Nice Guy: He is a very sweet and cheerful fellow and unlike their mothers, he gets along very well with Jenny.
  • Plant Person: A big contrast with his metallic robot cousin, Jenny.
  • Simpleton Voice: Speaks this way, likely to contrast with the high-tech Jenny.
