Heroes

Jenny

Global Response Unit XJ-9/Jennifer "Jenny" Wakeman

Voiced by: Janice Kawaye, Leisha Medina (Latin American Spanish)

"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?"

The main protagonist and the "teenage robot" (built five 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 teenage 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.
• Age-Inappropriate Dress: Taking into account her body parts that count as "clothing", she appears to have a crop top, a miniskirt, and thigh-high boots. Not an outfit that would normally be seen as formal.
• 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 doesn't get her way.
• All of the Other Reindeer: Zig-Zagged. It seems as though no matter what she does on a daily basis, she will always somehow end back up as the school freak...but that doesn't stop her from at least being respected as a hero by her peers, although this is more of a case of Depending on the Writer.
• Animal Motifs: Spiders pop up several times during the show. First there's her spider-legs function, then there's the time she outright transformed into a spider to scare the Crust Cousins, and lastly, there's Cluster Prime's anti-Jenny propaganda video, comparing her to a spider. The last example makes sense when you remember that Cluster Prime's military/elites is made up of Mechanical Insects, insects being the main prey of spiders.
• 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. They even provide the page image.
• Astro Clone: Jenny is a superpowered Robot Girl who just wants to be a normal human teen. Her mother has a design similar to Dr. Tenma, but she's a benevolent parent (besides her being unsupportive of Jenny's "human name" and her desire to be normal). Jenny has a blue-and-white scheme with pointy Girlish Pigtails, similar to Astro's pointy Robot Hair.
• Badass Adorable: A One-Man Army that is also a cute robot girl.
• Balloon Belly: She has inflated more than once, despite being made of metal.
• Bare Midriffs Are Feminine: Being a girly robot, Jenny's design is meant to give this impression, with blue plates at her chest and waist mimicking a crop 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. Thankfully, she seldom use her powers against anyone for revenge.
• Big Little Sister: She's the ninth and most recent of the XJ prototypes, but since she was designed with a body roughly mimicking a teenage girl, she towers over some of her sisters.
• Big Sister Instinct: Jenny is rather protective of Tuck, and generally treats him like he was her little brother. His screaming even helped her when Fighting from the Inside.
• Bifauxnen: A few outfits of hers make Jenny look bulky, such as the quarterback kit in "Grid Iron Glory", a select few in "Victim of Fashion" and her persona as Ruby Rocket in "Girl of Steal".
• Blue Is Heroic: Her body is white with dark cyan 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 has her moments of rebelliousness, selfishness, and acting like a delinquent to her mother, but being that she was built in the image of and programmed with the personality of one, it's a given.
• 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).
• Catchphrase: Crikey!
• Character Title: The "Teenage Robot" part refers to her.
• Clothing Appendage: The blue parts of her body besides the Robot Hair resemble a tube top, miniskirt, and boots.
• Curtains Match the Window: Her hair and outfit colors match.
• Cute Bruiser: Built like a bubbly, adorable teenage girl that is a super robot that regularly pummels monsters into the ground.
• Cute Machines: 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 XJ-9, 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.
• Destructive Saviour: She often causes buildings to get destroyed when she fights monsters, much to the dismay of the citizens of Tremorton.
• Depending on the Writer:
  • Jenny's unpopularity at school. She's either a easily-ridiculed butt-monkey that's seen as an outcast by everyone or is seen as just another student that everyone else are cool with.
  • Water usually makes her rust, but in "The Great Unwashed", water seems to not ever rust her in the slightest.
• Ditzy Genius: A highly advanced and intelligent combat android, but she's pretty clueless and is usually a complete screw-up 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.
• Dude Magnet: Kenny and Lil’ Acorn both fall in love with her at first sight, and despite being a robot, she attracts several human boys throughout the show. Sheldon is madly in love with her, and Brad and Tuck are both hinted to have a crush on her a couple times. Her second outing with the exo-skin also quickly attracts many interested looks from many male observers.
• Early Installment Character-Design Difference: In the original Oh Yeah! Cartoons pilot short, she was visibly larger, her hands were the same coloring as her hair and "clothes", she had lips, and her skirt had rivets on the bottom.
• Endearingly Dorky: All she wants in life is to blend in with her human classmates, and her attempts at such are rather adorable.
• Expressive Hair: Not a big example, but her hair does droop when she's sad and points straight up when she’s happy, excited or angry.
• Extended Disarming: Does two variants. When up against Armagedroid, she pulls out another weapon for every one he rips off her in a protracted fight. When undergoing a liposuction allegory in "Victim of Fashion", Sheldon pulls out a massive pile of weapons and gadgets, including a working sink.
• Fem Bot: She's a female robot built with a feminine shape. Taken up to 11 in the second "Raggedy Android" episode, where the exoskin she wears turns Jenny into a curvaceous redhead that every guy in Tremorton wants.
• Gasshole:
  • In chapter 12 of the newsletter story "Alternaversity", Jenny accidentally released a "rancid plume of black smoke" (read: massive fart) on the audience during her aerial performance in the Tremorton High talent show after drinking the highly volatile Canopus 13 on the night before. The Crust Cousins, of course, mocked her for this on stage in the lyrics of their song, adding to her humiliation.

  • Also in the episode "Crash Pad Crash", her engine released a puff of smoke from her "backside" when she was low on fuel
  Nora: Looks like someone’s on their last bit of laughs gas!
• Genki Girl: She's quite excitable and with a positive attitude.
• Girl Next Door: She’s the next door neighbor to Brad and Tuck. Minus the romance, of course.
• 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 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.
• Good Is Not Soft: Make no mistake, Jenny is a good person deep down, but when she's truly annoyed by someone or something, she's not one to hold back any speeches or her strength and likes to apply equal consequences to the situation.
• Hair-Trigger Temper: Her temper is very human-like. Add in her various weapons and gadgets, and making her mad is something you don't want to do.
• Hartman Hips: While not her normal robot form, this trope applies with her new Exo-Skin form in "The Return of Raggedy Android", as the skin's hips are very wide.
• Head-Turning Beauty: Despite being a robot, she’s seen as this in "The Great Unwashed" when she gets a makeover, and in "Victim of Fashion" when she puts on a fresh coat of wax, as well as every time she puts on a new outfit.
• 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 (primarily at school) occasionally treat her like garbage. A particularly nasty example of this occurs in the Christmas special where she spends a year under mind control that causes her to destroy holidays and when she manages to escape, even Brad, Tuck and her own mother believe she did those things by choice. Her classmates also hate her in "Killgore" for trying to hurt Killgore, despite Killgore being a Card-Carrying Villain. She manages to get some well-earned respect she yearned for after "Escape from Cluster Prime" and is eventually promoted by General of Skyway Patrol a "city treasure" in "A Spoonful of Mayhem".
• 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" and is the tallest girl in her school.
• 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.
• Immunity Attrition: She may be tough but she has her limits. Many times she gets beaten up to the point where she can hardly fight, most notably against Misty, Armagedroid, and Gigawatt.
• Impossibly-Compact Folding: Despite being relatively human-sized, her transformative capabilities as a Telescoping Robot allow her to whip out a variety of Retractable Weapons and gadgets for any and all occasions (melee combat weapons, lasers and Death Rays, explosives, many methods of flight, survivalist tools, cosmetic changes and pointless little doo-dads) in a way that would be impossible outside of a cartoon.
• Innocently Insensitive: She comes off as this at times, such as when she pronounced the "P" in Pteresa’s name, not knowing that the "P" is silent.
• In-Series Nickname: Her friends, mostly just Brad, call her “Jen”. She's only referred to by "Jennifer" at times by Nora, Vexus, and some of her teachers.
• 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.
• Kid Hero: Has the mentality and appearance of a teenage girl, but she’s technically only five years old.
• Leeroy Jenkins: She's prone to going into battle without a plan and ends up bringing the following chaos with her.
• Light Is Good: A white robot with navy blue clothes and hair and is The Heroine of the show.
• Lightning Bruiser: She possesses super strength and speed, being able to lift a 100,000 ton pyramid 'while' flying at near-faster than light travel.
• 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 Loser Protagonist, falls in love with the Superheroine Fembot who saves him from bullies, and becomes her Dogged Nice Guy. Too bad she's not interested.
• Magic Skirt: Justified, as that "skirt" is made out of metal and is actually her pelvis. In one official promotional material, Brad and Tuck are seen accidentally taking her underwear out of her drawer, implying that she indeed wears metallic panties, though this was later retconned in the episode "Crash Pad Crash".
• 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.
• Morality Pet: Seems to be one towards Misty, as the latter wanted money in return for her services but was willing to help Jenny without charging her.
• Motor Mouth: She talks noticeably faster than other characters. Then there's the time she tried to ask Silver Shell to a school dance.
• Ms. Imagination: Becomes this in "Daydream Believer" after her mother installs a dream chip into her system.
• Nice Girl: She's a cheerful, kind, and sweet girl who just wants to fit in.
• The Noseless: She has no visible nose, given that she is a robot, unless you considered her pointy cheekbones as a nose,
• Omniglot: She has software that apparently allows her to speak any language, though we just see her speaking English and Japanese.
• One-Woman Army: She’s capable of taking down an entire alien invasion on her own and any of the threats the Earth faces.
• 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/drink anything besides oil.
• Robot Hair: She sports a pair of metal pigtails. They house two of her jet thrusters outside of her wings and bootjets.
• Shapeshifter Baggage: Jenny is heavy, but nowhere near as heavy as she should be if she bore the true weight of all her mechanisms. It becomes a plot point in "Victim of Fashion" that, while capable of emulating highly elaborate fashions with her devices, she cannot make herself any smaller than she already is.
• 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?
• Single Woman Seeks Good Man: By the end of "Weapons of Mass Distraction", she’s sick of smooth guys who turn out to be jerks, and wants someone sweet and sincere. Sheldon walks by, and she greets him, still wondering where she can find someone like that. Sometimes, though, Sheldon is set back by more dubious actions he'll take for her affection.
• 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.
• Slapstick: She tends to suffer more injuries than the rest of the cast, given she's a robot and not a human. Being that she only had pain receptors installed for one episode, it's more an inconvenience for her being that she's still a robot and thus can be repaired by her mother.
• Smug Super: Veers into overconfidence at times due to being an overpowered robotics unit, causing her to frequently tempt fate.
• The Smurfette Principle: The only one in her main group of friends to be female. Her only other female friends either became evil like Misty or only appeared once in the show such as Vega.
• Statuesque Stunner: She's 6 1/2 feet tall (though this seems to include her hair) and really cute to boot.
• Stalker without a Crush: When she is suspicious of Melody hanging around Brad, she follows them around town, because she’s looking out for Brad. Given that she and Brad are Platonic Life-Partners, she (probably) isn’t doing it out of jealousy of losing him to Melody.
• Stripperiffic: The parts of her body that suggest clothing are oddly skimpy, consisting of a very small crop top with a miniskirt. ^note Which is even worse when you consider the fact that she’s technically only five years old.
• Super-Strength: "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. Additionally, she mentions she weighs 600 pounds.
• Telescoping Robot: She provides the trope picture.
• Token Robot: The only robot in her group of friends and attending her school, unless you count Kenny, who was only in school in his debut appearance.
• Tomboy and Girly Girl: Jenny plays the girly girl to Misty's tomboy, being a girly fembot to Misty's rough Bifauxnen.
• True Blue Femininity: She’s quite feminine, and her hair and outfit is blue.
• Weaksauce Weakness: Water tends to fry her circuits or rust her metal shell.
• Well-Intentioned Extremist: Both violently and non-violently, Jenny can pull some ridiculous methods if it's to get rid of whatever Monster of the Week is attacking Tremorton (or alternatively whatever teenage plight is occurring for her), but she has good intentions behind all of it. Unfortunately, it also makes her destructive and leads to her having a bad reputation because of her extremism.
• 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.
• Your Size May Vary: Despite being 6'6'', Jenny is either visible taller than everyone or is barely taller than the 5'6'' Sheldon.
• 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

Bradley "Brad" Carbunkle

Voiced by: Melissa Denton (Oh Yeah! Cartoons pilot), Chad Doreck (main series), Jhonny Torres (Latin American Spanish)

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.
• 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.
• Bumbling Sidekick: Most of the time when he tries to get in on the action and help his best friend fight crime, he usually screws up and XJ-9 has save him and the day. But he can be quite capable at times.
• 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 his friend 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.
• 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.
• Deuteragonist: As largely in focus as Jenny herself.
• Distressed Dude: His gung-ho attitude frequently results in him needing to be rescued.
• Early Installment Character-Design Difference: The original Oh Yeah! short depicted him with less stylized hair, red hi-top sneakers instead of black shoes and wearing brown pants with patches on the knees, a red shirt and a white and olive varsity jacket instead of gray pants, a white shirt with a black sweater vest.
• 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, while he doesn't have a bad temper, 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, his brief marriage to Tammy, 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.
• The Mentor: To Jenny, even though he's a teen like her, he often helps her overcome her problems and work things out.
• 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.
• Only Sane Man: He is the most level-headed person in most situations and is the only one Jenny can turn to for help.
• Platonic Life-Partners: With Jenny, usually. Most of the time, they act like they’re just friends, although there are a few rare moments where Brad’s implied to have a crush on her.
• Redheads Are Uncool: Isn't too popular at his school, although not to the same extent as Sheldon.
• Ridiculously Average Guy: Though he wishes to be more than that.
• 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.
• Ship Tease: There are a couple moments where he’s hinted to have a crush on Jenny. In "No Harmony With Melody" he fantasizes about singing on a stage for an audience of adoring fangirls, including Jenny, and in "Ball And Chain", he’s shown to have a drawing of Jenny in his school locker.
• 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.
• Wise Beyond Their Years: He is a kind, well-meaning teenager with lots of insight on the world and social life, and educates Jenny when she needs it.

Tuck

Tucker Carbunkle

Voiced by: Audrey Wasilewski, Maythe Guedes (Latin American Spanish)

Brad's little brother.

---

• Absurd Phobia: In "Raggedy Android", he tries to face his fears on the Ferris Wheel. He's not afraid of heights or anything: just giant wheels.
• Annoying Younger Sibling: Tuck can sometimes be annoying, mostly because he's such a scream king, 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 always going on adventures with his brother and knows almost as much as Dr. Wakeman about robots.
• Bratty Half-Pint: He's a real nuisance to Jenny, Sheldon, and Brad.
• Cheerful Child: Tuck is very enthusiastic and smiles almost constantly.
• Deadpan Snarker: Most likely the one to make a sarcastic comment out of the whole main cast.
• Depending on the Writer: He is either a well-meaning troublemaker or a completely unsympathetic brat.
• Distressed Dude: Even more than his brother, frequently being afraid of many things that he encounters.
• Early Installment Character-Design Difference: The original pilot depicts him wearing a baseball cap and a white T-shirt with red accents rather than going bare-headed and wearing a red shirt with a black stripe and collar.
• Hero-Worshipper: To the Silver Shell, as shown in the episode "A Pain in My Sidekick", and to Jenny, though the latter doesn't come up that often.
• Innocently Insensitive: Given he is a younger kid, he doesn't understand self-control or basic boundaries of people, and having good manners.
• 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, though it was zigzagged in "Tuckered Out" As while he did get a passing grade he also got publicly humiliated for the way he treated everyone else.
• 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.
• Laser-Guided Karma: When his actions actually bite him in the ass, most notably in The Boy Who Cried Robot.
• 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.
• Precocious Crush: He shows one towards Jenny a couple times. In "Future Shock", he asks Jenny on a date, and in "The Price of Love", he buys a picture of Jenny from Sheldon when Sheldon has a yard sale.
• Secret-Keeper: As of "A Pain in My Sidekick", he's the only one who knows Sheldon is the Silver Shell.
• 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. Wakeman

Dr. Noreen "Nora" Wakeman

Voiced by: Candi Milo, Edylu Martínez (Latin American Spanish)

An elderly spinster robotics scientist and the one who built the XJ robots, who is often simply refered to as "Mother" or "Mom" by Jenny and her sisters.

---

• Abusive Parents: To the other models of the XJ line, who she keeps deactivated in the basement for being imperfect. They are notably gleeful to get the chance to attack her when reactivated and used by the Villain of the Week.
• 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 her to share some embarrassing detail about Jenny's design or maintenance.
• Badass Adorable: Is fairly short and cute, if a bit reserved, but she is a bona fide Action Mom and Skyway Patrol veteran.
• Big Good: She is Jenny's creator and caretaker, so she's usually the one everyone relies on when Jenny's actions lead to disaster.
• Cool Old Lady: A elderly woman who is able to create many advanced robots. She even fought Vexus 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 human-like nature and now lets her live as the typical teenage girl she designed her to be, allowing Jenny to interact freely with humans.
• Dude Magnet: Implied to be one at the end of “Mama Drama”.
• Early Installment Character-Design Difference: She had a different hairstyle, wore completely different glasses, a less longer nose, and her clothes were completely white a-la Dexter in the pilot short on Oh Yeah! Cartoons.
• Einstein Hair: Her hair is white, spiky and messy.
• 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.
• Gag Nose: She has a long, pointy, erect nose. While it isn't pointed out often, Sheldon calls her a "birdnose" and later she uses it to poke Vexus' eye in "Escape From Cluster Prime".
• Insistent Terminology: As Jenny's creator, she often calls her by her designation "XJ-9".
• Jerk with a Heart of Gold: She can be strict, sometimes restrictive, and often meddles with Jenny's life but deep down loves her and wants what is best for her.
• Mad Scientist: One of the saner ones, but some of her wilder 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 or mistreating Jenny while she's around. Especially since she's a Retired Badass
• Maiden Aunt: She is an unmarried aunt to her nephew, Glenn Wakeman, though both Wisteria and Nora are Truly Single Parents.
• 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".
• Nice Job Breaking It, Hero: She tends to leave a lot of dangerous sentient robots and old failures with old grudges that end up returning to cause trouble and get payback for her mistreating them.
• 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.
• Parental Favoritism: Although she created the entire XJ series and they call her "Mother" or "Mom", she only really sees Jenny as her daughter and the other ones not so much. Partially justified as the other XJ units are flawed prototypes.
• 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.
• Redheads Are Uncool: When she was a young child she had red hair and was looked at as an outcast.
• Shorter Means Smarter: One of the shortest people on the show, but almost one of the (if not most) smartest characters.
• 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, Jenny, and Wisteria's Plant Person son, Glenn.
• Shipper on Deck: When Nora first sees Sheldon and everyone is assuming he's Jenny's 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.
• Where Does He Get All Those Wonderful Toys?: It's never explained where Wakeman gets the funding for all her insanely destructive creations. She used to work for Skyway Patrol but has long since cut ties with them and is regarded as a crackpot by many. However, she is shown in one episode to be actually buying machinery at a robot's convention, so it's implied she's quite independently wealthy.

Sheldon

Sheldon Lee/Silver Shell

Click ^here to see Silver Shell

Voiced by: Quinton Flynn, Kaihiamal Martínez (Latin American Spanish)

Jenny's self-proclaimed romantic admirer.

---

• Abhorrent Admirer: Towards Jenny at first, but he mellows out of his stalking in later episodes.
• Ace Pilot: He's shown to be capable of flying alien spaceships competently.
• Agent Peacock: When he joins the secret agency, his codename is "Baron Von Fashionista III".
• All of the Other Reindeer: Absolutely EVERYONE in the school (save for Jenny and Brad) hates him and keep away from him at all times.
• Ambiguously Bi: In one episode he has a conversation with Jenny discussing which members of a Boy Band is the cutest.
• Ascended Extra: Went from a minor character in season 1 to pretty much one of the main characters by the end of the show.
• 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.
• Because You Were Nice to Me: He starts crushing on Jenny because she saved him from bullies.
• Benevolent Boss: During his time as a space pirate captain, an elderly Sheldon was considered a great leader by his crew members. When he left the crew to get back to Earth, the pirates followed him and assumed that their captain was kidnapped by Jenny.
• Big Brother Instinct: They're not related, but he was very protective of Tuck in "A Pain In My Sidekick", trying to 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 Wakemans' 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.
• 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?: He can't ever get any respect. Period.
• 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.
• Hated by All: Absolutely EVERYONE at school hates him. The bullies and popular kids hate him for being a nerd, and constantly pick on him for it. Brad doesn't seem to care that much about him and most of the time, Jenny is annoyed by his crush on her.
• 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: He’s a human with a one-sided crush on Jenny, a robot.
• Large Ham: As the Silver Shell, he has melodramatic and hammy dialogue to play up his being a superhero.
• Nice Guy: Despite his stalker tendencies and jealously issues, he's quite a friendly sweetheart especially to Jenny.
• 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. In "A Robot For All Seasons", everyone thinks Jenny became evil except for Sheldon, who believes that either a) Jenny was Brainwashed and Crazy or b) she has an Evil Twin, with the former option being correct.
• 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, implying that Sheldon really is only sexually interested in robots.
• Single-Target Sexuality: Jenny is the only person he's attracted to.
• Stalker Shrine: He has an abnormally large collection 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, although he still has his moments here and there.
• 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 she 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 been things like 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-as-Shell 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-Sisters

XJ's 1-8

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".

---

• Baby Talk: XJ-1 only babbles, cries, and whimpers like an infant.
• 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.
• Brawn Hilda: XJ-8 is enormous, bulky and speaks in a deep Machine Monotone, overall causing her to appear very masculine. She retains the Girlish Pigtails and miniskirt shared by many of her sisters, however, and is always referred to with female pronouns.
• 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".
• Crouching Moron, Hidden Badass: They're all quite a bit more eccentric and less competent than Jenny is, but never fail to pull through when it counts.
• 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 Dog Bites Back: Their final episode (and the unofficial final episode of the series) has them Brainwashed and Crazy and attacking Mrs. Wakeman. They all seem at least somewhat cognizant of the situation and are gleeful at the chance to get revenge against their neglectful mother.
• The Eeyore: XJ-7 is constantly depressed, even lamenting that she couldn't even destroy herself properly.
• Energy Weapon: XJ-2 is basically a laser gun with legs and eyes.
• Expy: XJ-7 is basically a female version of Marvin the Paranoid Android, her introductory line even directly referencing one of the books he came from.
• 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 - and importantly, build upon the previous iteration towards a humanoid robot that can function equally as a guardian and as a friend to humans.
  • XJ-1 appears to be an self-contained AI proof-of-concept. ...but as a result, she's a literal baby.
  • XJ-2 adds to this with mobility and a weapon. ...but she's no different from a self-propelled weapon.
  • XJ-3 is a humanoid form and miniaturization proof-of-concept. ...but suffers from structural integrity issues.
  • XJ-4 is capable of completing non-combat tasks and, importantly, interact with humans. ...but has a 'neat-freak' personality.
  • XJ-5 can fly and interact with humans well. ...but has a 'talky' personality.
  • XJ-6 can walk effectively. ...but has an inferiority complex.
  • XJ-7 has two humanoid arms and a durable form ...but she also has a tremendously morose personality.
  • XJ-8 has legs, is durable enough for combat, and her personality doesn't display the extremes her sisters do (actually a huge breakthrough, given how serious a flaw it is for XJ-4 through XJ-7). ...but has an imposing presence that won't help with human interaction, and a somewhat black-and-white personality.
  • XJ-9 is miniaturized into a human-sized form and is capable of full human socialization. ...but is heavily affected by said socialization, like an actual teenager.
• Girlish Pigtails: XJ-5, XJ-6, XJ-7 and XJ-8 all sport a Robot Hair-style pair.
• 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.
• Jerk with a Heart of Gold: XJ-6 spends most of her screentime acting spiteful about how everyone pays more attention to her sisters than to her, while XJ-8 generally acts like a needlessly blunt and aggressive security enforcer, but both immediately jump into action alongside their other sisters to help Jenny when she's in trouble. XJ-6 even states that she always puts family first.
• The Leader: XJ-5, perhaps by virtue of being the resident chatterbox, tends to take charge of the group when Jenny isn't around.
• Machine Monotone: XJ-8 speaks like this, though the tone changes depending on the episode.
• Middle Child Syndrome: XJ-6 appears to view herself as the constantly overlooked middle sibling, and is very resentful about it. More accurately, though, XJ-5 would be the middle sibling.
• 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, XJ-2, XJ-3 are closer to Robo-Monkeys, being like a human baby and toddlers, respectively. XJ-8 is also a lower-level Average Joe than the rest, being very blunt and inexpressive.
• 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.
• Team Mom: Along with being a Neat Freak, XJ-4 seems to be the most inclined to comforting the infantile XJ-1 when she's upset.
• The Unfavorite: XJ-6 is convinced that she's this, and constantly complains about it. To a degree they all count as this compared to Jenny, who is the only one among them that Dr. Wakeman views as a success.
• The Voiceless: XJ-2 and XJ-3 are completely silent. XJ-1 can't speak, but is capable of uttering baby babble.
• What Measure Is a Non-Human?: In a rather heartbreaking contrast to her treatment of Jenny, Dr. Wakeman doesn't think of any of these eight as being anything other than failed prototypes, and prefers keeping them deactivated in storage whenever possible. This leads to some conflict with Jenny, who views them as her younger sisters.

Villains

The Cluster

In General

• Fantastic Racism: They consider organic lifeforms, especially humans, to be a blight on the universe and seek to enslave them as an almost ironic role-reversal of how they use machines.
• Mechanical Insects: They are a race of humanoid robots with their military/elites having insect-like characteristics. Their queen, Vexus, is designed after bees with wings on her back, antennae and serves as the "Hive Queen" of them (with added Egyptian motif to reinforce this).
• Mechanical Lifeforms: They are a race of robots with no stated organic precursors who have built their own interplanetary society.
• Scary Dogmatic Aliens: A mix of "Communist" and "Conquistador" Variety. Cluster Prime is seen as a haven for robots of all types, though its inhabitants are fed a steady diet of propaganda to ensure the status quo, regular Cluster citizens being denied the chip that gives them their transformative abilities using Jenny as a convenient scapegoat. Everywhere else they are a dogmatic race of conquerors that try to recruit other robots (Vexus trying to convert Jenny regularly) and enslave all other lifeforms they come across.

Vexus

Queen Vexus

Voiced by: Eartha Kitt, Cree Summer ("Around The World in 80 Pieces" and as QT-2 and Vicky)

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.

---

• Animal Motif: She and the Cluster Army clearly resembles insects, Vexus in-particular resembles that of an Egyptian Sacred Scarab with her Nepharious Pharaoh appearance.
• 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: She's devolved into this by the season 3 episode "Queen Bee". After losing her planet, she's overjoyed at the idea of being adored by everyone at Tremorton High.
• 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 has a lot of queen bee motifs.
• Big Bad: As the leader of the Cluster, Vexus functions as the main villain of the series.
• Bitch in Sheep's Clothing:
  • She'll figuratively (and often literally) put on the guise of a human being or fellow robot to give off the impression of a good samaritan when she's the exact opposite.
  • If "Escape From Cluster Prime" was any indication, she was this to her own people, with none of the Cluster Prime citizens having any clue she was evil until Vega publicly revealed it.
• 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 third 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: Not even losing her entire planet and empire will deter her from attempting to destroy Jenny, and humanity by extension.
• Depending on the Artist: Her appearance almost never remains consistent throughout the entire series.
• Diminishing Villain Threat: Justified. Vexus remains a fairly consistent threat across the first two seasons, until she's dethroned by her daughter in "Escape From Cluster Prime". Without access to her army, resources, or public support from her own people, Vexus can't realistically threaten the Earth-like she used to. By her final appearance, her ambitions have decayed to ruling a high school because of her popularity, rather than taking over the planet.
• Even Evil Has Loved Ones: She does care about her daughter, to the point the latter considers her overbearing. Also included is the Nanobot she used to infect and brainwash Jenny with in "Hostile Makeover", which, after it was removed Jenny threatened to destroy if she harmed Tuck in any way.
• Evil Matriarch: Of Cluster Prime and the empire as a whole.
• Fantastic Racism: Doesn't like humans very much, even labeling them "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 misled by Vexus' propaganda that paint Jenny as a horrid monster.
• Greater-Scope Villain: In episodes where Smytus or Krackus serve as the antagonists, being the head of the empire they defer to.
• Hartman Hips: Her hips and thighs are wide enough to reach her torso.
• 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 has been reduced to trying to take over a high school, a far cry from her planetary conquests.
• 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.
• Inconsistent Spelling: Subtitles on the episodes often misspell her name as “Vexas”.
• Join or Die: Her general philosophy when it comes to assimilating robots into the Cluster.
• Knight of Cerebus: While she definitely has her comedic moments, Vexus gives off an entirely different vibe and is usually played more seriously compared to other villains Jenny has faced. She even nearly succeeds in turning Jenny into a member of the Cluster in her debut episode.
• 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.
• Let's Get Dangerous!: In "Escape From Cluster Prime", Vexus finally gets fed up with Jenny constantly foiling her plans, so she gathers up her entire military and outright invades Earth.
• 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.
• Ms. Fanservice: Despite her exotic, insect-like appearance, she is a tall, downright gorgeous robot with long, curvy legs, wide hips, and speaks in a sultry tone.
• Nepharious Pharaoh: With her nemes headgear, wadjet-like eyes and what looks like a solar disc between her antennae Vexus' appearance has a definitive Egyptian motif and she is a ruthless despot.
• Really 700 Years Old: Actually 2000 years old. In "Queen Bee", she disguises herself as a teen and was popular enough to take over Jenny's school. Jenny exploits this trope to make the student body turn on Vexus, since they want nothing to do with an old person.
• Revenge Before Reason:
  • She had already shown shades of this early on during "Escape From Cluster Prime", as if it weren't for Smytus, she would have kept the invasion on hold till she got a chance to finally destroy Jenny.
  • In "Trash Talk" she plans to blow up the planet Jenny is on, despite being on the planet herself and having no viable way off. She did consider that fact, however, and built a ship for her, Krackus, and Smytus to escape off of. Unfortunately, due to both limited resources and her declining sanity, said ship is the size of a thermos.
• Sanity Slippage: By her appearance in "Trash Talk", she's lost more than a few screws, planning to blow up a planet she's on and escaping in a pod that can only fit a hamster. She gets better by "Queen Bee".
• Shadow Archetype: For someone who despises humanity and boasts about robot superiority, she herself possesses some of their worst traits, being a ruthless, manipulative dictator who lies to her own people and forces other machines to convert to her collective.
• Statuesque Stunner: She is slightly taller than Jenny and has an exotic yet attractive design and figure.
• 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 were over for almost a century now.
• Tsurime Eyes: Her eyes are slanted upwards.
• Unexplained Recovery: For her last appearance. After always getting away unscathed during the first two seasons, she finally gets kicked off of her planet and launched into space at the end of the Season 2 finale. She shows up being stranded on the Garbage Planet with Smytus and Krackus in Season 3, where the episode ends with the entire planet exploding with all three villains still on it, and even moreso, their plans for escape being confirmed to have failed. Inexplicably, Vexus shows up again in a later Season 3 episode to terrorize Jenny at her high school, with mentions of her losing her status as queen confirming that it is in fact chronologically later, but no explanation for how she survived being on a planet that exploded with her on it.
• 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.
• Villain Decay: As the head of the Cluster Empire, Vexus was the biggest threat of the first two seasons. In the Escape From Cluster Prime special, she loses everything; her armies, her planet, and even her own daughter's turned against her. She returns in season 3, stranded on a junk asteroid and gone insane. While she regains her senses later on, she never approaches the same scope of villainy as she did with her empire.
• We Can Rule Together: She makes this offer with Jenny, trying to get her to help her robot brethren, destroy the human race, and become Cluster royalty. You can guess what Jenny's answer was.

Smytus

Commander Smytus

"My brilliant plan is working perfectly! I must remember to congratulate myself later."

Voiced by: Steve Blum

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

---

• Affably Evil: He can be surprisingly friendly and affable for an evil, militaristic villain.
• 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.
• Baritone of Strength: Comes with being voiced by Steve Blum.
• Big Creepy-Crawlies: In keeping with the Cluster's bug-theme, Smytus resembles a large rhinoceros beetle.
• Bond Villain Stupidity: His Fatal Flaw, complete with Evil Gloating, 10 second countdowns, the whole set.
• The Brute: Compared to Vexus, who prefers deception and subterfuge, Smytus prefers to employ more direct methods of assimilation. Ironically, this makes him more competent than Vexus as the series wears on.
• Card-Carrying Villain: If his "DESTROYER OF WORLDS!" speech is anything to go by, he really enjoys being a villain.
• The Dragon: For Vexus. Smytus is the commander of the Cluster's military and acts as her second-in-command as they invade Earth.
• Dragon Their Feet: Vexus and defeated and dethroned in the climax of Escape From Cluster Prime but Smytus is still threatening Earth with the main invasion force. Fortunately for the heroes, Jenny deals with him quickly once she returns to Earth.
• Dude, Where's My Respect?: In his first appearance, he laments that Vexus gives him demeaning nicknames.
• Early Installment Character-Design Difference: A minor example, but his eyes were much smaller in his debut appearance.
• Evil Gloating: Thanks to his ego, he will engage in this any chance he gets.
• Evil Is Hammy: As demonstrated with 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 pretty low-pitched.
• Fantastic Racism: Like the rest of the Cluster, he doesn't hold "fleshbags" in very high regard.
• Half the Man He Used to Be: After blowing himself up at the end of "Escape From Cluster Prime", Smytus is reduced to a torso, and is forced to walk on makeshift legs cobbled together from junk.
• How the Mighty Have Fallen: By season 3, he's lost his armies, his status, his pride, and half his body. Revenge is the last thing on his mind; he just wants his legs back.
• Hyper-Competent Sidekick: As the series goes on, Smytus steps into this role. Whereas Vexus grows an unhealthily obsession with Jenny, Smytus remains focused on the Cluster's goals on conquest. This culminates in "Escape From Cluster Prime", where he takes control of the invasion when it becomes obvious Vexus is wasting time and resources on Jenny. He nearly conquers Earth easily, whereas Vexus had spent the last two seasons utterly failing to do so. He's also smart enough to consider the possibility that the planet is more trouble than it's worth and opts to destroy it instead, rather than obsessing over it like Vexus.
  Vexus: Where is XJ-9? The decimation of Earth is finally at my fingerips and I refuse to fight this battle without her!
  Smytus: Well, I don't.
• 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]
• 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 hammy speech.
• Large and in Charge: He's bigger than most of the established Cluster villains, and is their military commander.
• Laugh with Me!: He has to order his minions to engage in an Evil Laugh with him... like they mean it.
• Meaningful Name: Smytus sounds like it's derived from "smite," meaning "to defeat and/or conquer," which fits his occupation as a conquering warlord.
• Near-Villain Victory: Has came close to winning at least twice.
  • He'd successfully assimilated Jenny, along with 7 of the other XJ-sisters, and was about to have her destroy her own mother... until XJ-1 barfed in her face, snapping her out of it.
  • In the special, he nearly destroyed the planet in Jenny's absence, until he was foiled again by her timely intervention.
• Not Quite Dead: He seemingly perished at the end of Escape From Cluster Prime when he activates his self-destruct, but later shows up in season 3... Half the Man He Used to Be but alive nonetheless.
• Paper-Thin Disguise: He puts on a wig and tries to pass himself off as Smytlana, a Ukrainian supermodel. After a short while of being complimented, he falls for the disguise himself.
• Post-Final Boss: In Escape From Cluster Prime, Jenny finally cripples Vexus's empire by turning its people against her, but still has to deal with Smytus threatening to destroy the earth. By that point, however, Smytus is more of a loose end that needs tying up.
• Self-Destruct Mechanism: He has one literally stored up his sleeve. Of course, it comes with a ten second countdown, as well.
• Small Name, Big Ego: Downplayed by the end of the series. Smytus is actually fairly competent, so it's unlikely his "destroyer of worlds speech" is all bluster, though he still thinks too highly of himself and comes off as a tryhard with his gloating.
• Smug Snake: Credit where it's due, Smytus is a capable villain, but he often overestimates his abilities and indulges in gloating far too often, which bites him hard.
• 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: With his ship, armies, and robot factories in ruin, Smytus activates his self-destruct to destroy Jenny and take as many humans with him as possible, as a final act of defiance and spite. It doesn't work quite the way he intended, as said self-destruct came with a ten second countdown, giving Jenny time 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 one more thing 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, yet he has very stumpy legs.
• 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 right before it explodes. Woops.

Krackus

Krackus

Voiced by: Jim Ward

Vexus: This better not be another crackpot invention.
Krackus: It isn't! I mean, it is, but this time it worked!

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: He may be an old coot with a failing memory, but he's still a capable inventor. Like what Nora tells her daughter, "Don't underestimate him! Sooner or later he may invent something that actually works!"
• Big Creepy-Crawlies: He bears a resemblance to a large beetle or cockroach.
• Bungling Inventor: He's pretty clumsy and most of his inventions fall apart after being used once.
• Evil Genius: He's the brains of the Cluster, though everyone else believes otherwise.
• Evil Old Folks: A crackpot inventor with a few screws loose, but is one of the Cluster's top inventors.
• Informed Flaw: He's treated as a joke by most characters mostly due to being a completely senile old man, but his inventions largely work as intended.
• Meaningful Name: Krackus' name is likely derived from the term "crackpot", which fits with how foolish he can be in both personality and his inventions.
• 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, whereas Vexus is completely off her rocker and wants to blow up the planet (despite having no way off), and Smytus wants to get a new pair of legs, regardless of 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.
• Rollerblade Good: Fits under the 'Whose feet are wheels' variant.
• Uncertain Doom: Krackus, Smytus, 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 due to the show's abrupt cancellation.

Independent Villans

Killgore

Killgore

"I would like to destroy mankind."

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.

---

• Badass Adorable: He managed to outsmart Jenny twice and rebuild Armagedroid, who is millions of times Killgore's size.
• Bait-and-Switch Character Intro: His first scene introduces him as a deep-voiced silhouetted seemingly-hulking figure only for the lights in the toy store he's in to be turned on to reveal his bright color scheme, and the shop owner walks over and winds him up to reveal he's not only tiny, but his real voice is very high-pitched.
• Bratty Half-Pint: He drives Jenny bonkers in his debut by virtue of pestering her to "SURRENDER!"
• Card-Carrying Villain: Killgore insists you read his tag!
• Character Catchphrase:
  • Surrender
  • "BA-NAH!"
• Cute Is Evil: He's considered the cutest thing ever in-series, and a Card-Carrying Villain through-and-through. Jenny's biggest problem with facing him is that she can't fight back without people hating her for it.
• Deathbringer the Adorable: Sure the name may sound threatening, but it's so gosh-darn cute!
• Determinator: To his credit, he's persistent. He spends most of his debut annoying Jenny into submission.
• Enemy Mine: With Jenny in the end of his debut episode and most of "Enclosure of Doom".
• Evil Is Hammy: He yells a lot and he’s very melodramatic.
• Evil Sounds Deep: He has a very deep voice when not wound up, otherwise he sounds very high-pitched. The first few seconds of the episode he's introduced in has him not wound up yet as part of his Bait-and-Switch Character Intro.
• Expy: Seems to be one of Invader Zim. He's a short hammy non-human with a high pitched voice and speaks in Third-Person Person who wishes to please an intergalactic Evil Empire by destroying mankind while having delusions of grandiose. He causes grief for the main hero, but nobody else seems to care for his villainy.
• Harmless Villain: To the point where he was outright rejected by the Cluster. But he does somehow manage to enlist the help of ''Armagedroid'' in his second episode.
• Ineffectual Sympathetic Villain: Once Jenny has a chance to destroy Killgore with no one being the wiser, she decides she can't hurt a defenseless creature even if it's driving her crazy.
• Instant A.I.: Just Add Water!: Why a windup toy is sentient is not remotely addressed.
• Laughably Evil: He provides a lot of humor with his Large Ham tendencies, his futile attempts to defeat Jenny, and his wanting to be considered a threat while being irritated by how most people find him adorable.
• Loved by All: Everyone adores Killgore for his cuteness. The only people who don’t like him are Jenny, who he drives crazy, and evil villains like the Cluster. And Jenny still sometimes acts fond of him.
• Made of Indestructium: Somehow able to resist being crushed by a closing-walls Death Trap, albeit only for about 8 seconds.
• My Little Panzer: As much as he claims otherwise, nothing about Killgore's design is dangerous—any danger he poses is instead a result of trickery and persistence.
• The Napoleon: If its 10 1/2 inch stature is any indication.
• Not-So-Harmless Villain: Yes, he's tiny and pathetic, but he has moments that prove he can be a legitimate threat:
  • In his debut episode, Jenny, driven crazy by Killgore but unable to bring herself to destroy him, hatches a plan to get him to leave her alone by pretending to surrender to the Cluster (actually Brad and Tuck in Paper-Thin Disguise). The plan backfires when it turns out Killgore contacted the real Cluster in advance.
  Killgore: Killgore is small. Killgore is not stupid.
  • His next appearance, "Enclosure of Doom," cements him as this. Remember Armagedroid, the Humongous Mecha that nearly killed Jenny the first time they fought? While it's never revealed how, Killgore was able to rebuild him completely.
• Scare Chord: He keeps saying the classic "buh nah" chord.
• Saying Sound Effects Out Loud: SMACK! SLAM!
• Third-Person Person: Kilgore sometimes talks like this.
• Torment by Annoyance: SURRENDER!
• Villain Team-Up: With Armagedroid in "Enclosure of Doom", it worked...a bit too well.
• Villain with Good Publicity: Despite ranting about how evil he is and how he wants to destroy the human race, all humans love him.
• Wind-Up Key: It's powered by a watch spring and a wind-up key.

Armagedroid

Armagedroid

Voiced by: Kevin Michael Richardson

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: Its directive was to destroy weapons, and when it defeated an armada of hostile aliens, it turned its fangs on humanity, believing peace required destroying anything of theirs that might be considered a weapon. Lacking any capacity for independent/humanlike thought, Armagedroid technically was still doing exactly what he was created to do... only on a much larger scale than what Dr. Wakeman intended, as his ultimate goal was essentially to rid the Earth of weaponry.
• Back from the Dead: After getting blown up, Killgore somehow rebuilt him entirely.
• Cain and Abel: The Cain to the entire XJ series, being an earlier Wakeman prototype that has a vaguely similar color scheme.
• Curb-Stomp Battle: Any time Jenny battles Armagedroid, it ends with her severely damaged, and that's when she wins. The first time she tried her luck, she almost lost her life.
• Destructive Saviour: Armagedroid, who was built for the purpose of eliminating dangerous weaponry, something that proved to be dangerous in peacetime.
• Diesel Punk: He's got an Art Deco aesthetic to make him look older than the XJ series, which all have a Raygun Gothic look.
• Evil Is Bigger: Way bigger than any adversary Jenny's encountered.
• Evil Sounds Deep: Courtesy of Kevin Michael Richardson.
• Greater-Scope Villain: It's because of him that the XJ series was created, which in turn led to Jenny's creation. He's also the only villain who succeeds in causing Jenny critical damage without any problems. Despite this, he's also easily tricked into self-disposing.
• Humongous Mecha: Taller than most of the buildings in Tremorton.
• Invincible Villain: Literally nothing could stop him, even after tunneling to the Earth's core and wading in magma for decades. Jenny is forced to convince him to destroy himself somehow or set off a bomb from inside his own body to even stop him at all.
• Knight of Cerebus: Definitely not one of the more comical villains. He almost killed Jenny in their first battle!
• Knight Templar: He believes destroying all weapons will make the world safer, but his idea of a "weapon" gets so broad he starts destroying children's toys and kitchenware. He also doesn't care if he has to rip Jenny to pieces to disarm her.
• Logic Bomb: Armagedroid's goal is to destroy all dangerous weaponry, so when Jenny points out that he himself is a dangerous weapon, he self-destructs.
• Psycho Prototype: Armagedroid was created by Dr. Wakeman as a peacekeeping robot much like Jenny. The fact that he had no real identity beyond a destroyer contributed to his eventual rebellion, the XJ-series' Ridiculously Human personalities being because of this.
• Red Eyes, Take Warning: Huge red ones.
• Villain Team-Up: Was later somehow rebuilt by Killgore of all people. Unfortunately, it worked too well in Armagedroid's favor.
• What Did You Expect When You Named It ____?: Exactly what compelled Nora Wakeman to name a robot meant to protect humanity after the biblical equivalent of the end of the world?
• Would Hurt a Child: He resorted to trying to crush a baby in a highchair just because Armagedroid was trying to neutralize the Spork that the baby was holding.

The Space Bikers

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 biker 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 (violent) affections. He actually turned around for a while and saw it as an opportunity for adventure, until he realized she'd always treat him like a slave—and then eat him when they broke up.
• 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 Midriffs Are Feminine: They are female aliens with stereotypical "bad girl" outfits. Two of them, Olga and Sludge, wear clothes that leave their midsections exposed. They're also the ugliest two out of the five.
• Bitch in Sheep's Clothing: They are hardened criminals that cause mayhem and terrorize the innocent people of Tremorton for kicks, but on their home planet, they act as highly respected school teachers and were beloved in their community, at least until Tuck and Jenny managed to expose them in the end. Unlike most examples, they seem to genuinely care for the people they lie to and they do not hide away their vile side from the people they do hurt.
• Butt-Monkey: Lenny tends to be regularly roughed up by Letta. And the bikers as a whole always suffer when they mess with Jenny.
• Dominatrix: All of them are Hell-Bent for Leather, but Letta and Lenny are quite blatantly a dominatrix and her sub.
• Dressed in Layers: For some reason Letta wears her biker outfit under both a bridesmaid gown and her school principal clothing. Though it does look a lot like underwear.
• Ephebophile: Tammy hits on a teenager, yet her job on her homeplanet greatly implies she is an adult. It's possibly just her age varying by the needs of the plot, but the show probably only got away with it because she's an alien fishwoman.
• Elective Mute: Lenny can talk, but apparently only does so in during his day job as a janitor.
• Even Evil Has Standards: When their identities as school teachers get exposed, Tammy states spending all their time as violent bikers would "serve no purpose or greater good."
• Fish People: Their species sorta resembles the Creature from the Black Lagoon.
• Gonk: Sludge and Olga, who are visibly uglier when compared to Tammy and even Letta and Lenny.
• Green and Mean: They are trouble making thugs who all 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 and buttocks.
• Helium Speech: Tammy's voice is ridiculously high.
• A Hero to His Hometown: They're well-respected staff of a school on their home planet, where no one knows of their destructive "hobby". Or they were until they were found out (though Lenny still has his job as janitor).
• Huge Girl, Tiny Guy: Lenny is minuscule compared to all of the other Bikers, especially his wife Letta.
• Laser-Guided Karma: "Voyage to the Planet of the Bikers" ends with them their losing jobs and reputations as beloved teachers after everyone finds out what they do out of town.
• Living a Double Life: 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.
• Monster Is a Mommy: Sledge is revealed to have two kids and is currently expecting a third.
• Moral Myopia: They cause all sorts of destruction, including multiple attempts to eat people. When Jenny gets them to expose their bad side to their hometown, Letta complains that she ruined their lives over some "harmless pranks".
• Ms. Fanservice: Tammy, who's very attractive when compared to everyone else in the gang, especially Sludge and Olga, thanks to the occasional scenes where they focus on her wide hips and her butt.
• 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.
• Pragmatic Villainy: Sledge reasons that being bikers 24 hours a day isn't reasonable because how would they afford a living without steady jobs?
• 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.
• Slave to PR: They value their double lives as tough criminals and school teachers. They end up ruining the latter, and get blackmailed by Tuck and Jenny over the former.
• Sleeves Are for Wimps: A bunch of tough bikers, none of whom wear sleeves.
• Throw the Dog a Bone: Despite all the abuse Lenny takes, he is the only one of the gang who gets to keep his job as a school janitor once the Space Bikers' secret gets exposed.
• Villainesses Want Heroes: Tammy has a crush on Brad, Jenny's bestfriend/sidekick and in one episode, actually tried to marry him against his will. Brad briefly considered it, until he found out he'd be miserable and called off the marriage.

Dr. Locus

Dr. Locus

Voiced by: Grant Albrect

An evil mad scientist who is the father of Melody.

---

• The Bad Guy Wins: Nearly defeating the heroes aside, Dr. Locus successfully accomplishes his objective in "Bradventure" by copying Jenny's abilities and installing them into his daughter Melody.
• Bald of Evil: He has no hair on his head and is one of the biggest threats in the series.
• Beard of Evil: He's an evil scientist and 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, possibly around Nora's age, and is anything but nice.
• 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 killing 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.
• Non-Standard Character Design: Looks more like a Ren & Stimpy character.
• 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, which he failed.
• 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.

Gigawatt

Gigawatt

Voiced by: Nick Jameson

An energy vampire who drains power from anything electronic.

---

• Achilles' Heel: Being comprised of electricity makes him extremely vulnerable to water, which shorts him out.
• Curb-Stomp Battle: Because he's living kryptonite for electronics, he easily defeats Jenny in "Mind Over Matter" multiple times, to the point she enlists help from her mother and friends to defeat him.
• Evil Is Bigger: His size increases as he absorbs more energy.
• Evil Is Hammy: His voice and personality are reminiscent of Dracula.
• Knight of Cerebus: He's quirky, but Gigawatt's very nature is to drain power, which is lethal to an electronic like Jenny. His powers make him a walking EMP capable of inducing blackouts to entire cities with his mere presence.
• Villain of the Week: He shows up for one episode and is defeated by the end of it, never to turn up again in the series.
• Our Vampires Are Different: He's an energy vampire, in that he feeds on power rather than blood.
• Walking Techbane: His very presence in a city is enough to drain all power and cause mass blackouts.

The Exo-Skin

Exo-Skin

Voiced by: Grey DeLisle

A synthetic skin made to allow Jenny to pass off as a human being, until it gains sentience.

---

• Allegorical Character: The suit represent the dark side of Jenny's goals for social assimilation: Loss of Identity, stifling conformity, and heinous apathy to the people she's climbed past on the social ladder.
• Clingy Costume: Clingy skin. Upon gaining sentience, the skin wouldn't allow Jenny to simply remove it, even forcing itself back on in her sleep.
• Death of Personality: If it had its way, Jenny would still be the same beneath the skin, but unrecognizable in behavior.
• Expy: It's a sentient suit that eventually grows a mind of its own and doesn't like being separated from its host. Now, are we talking about the skin or Marvel's Venom?
• Female Misogynist: The suit is not exactly female in a biological sense, but it has a woman's voice, combines with Jenny to look like a young woman, and has a very regressive idea of femininity.
• Instant A.I.: Just Add Water!: Dr. Wakeman only mentions it being designed to let Jenny fit in physically. Instead, it develops its own, extremely manipulative personality that tries to redefine her entirely life.
• Obsessively Normal: The exo-suit only allows Jenny to act like "a normal girl", even if it means ignoring people who need her help.
• Politically Incorrect Villain: When it tries to help Jenny be a “normal” teenage girl, it refuses to let her save the day from villains, because normal girls don’t save boys.
• Royal "We": It uses this when attached to a host.
• Vanity Is Feminine: The "normal girl" the suit tries to turn Jenny into is stuck-up, haughty, vain, and gets the guys around her to do everything for her.
• What Happened to the Mouse?: Was last seen latching on Mr. Mezmer in "The Return of the Raggedy Android" and was never seen or heard of again. And since that episode occured early in the first season, the fact the show was cancelled doesn't fully explain its absence.

Lil Acorn

Lil Acorn

Voiced by: Dee Bradley Baker

A robotic ventriloquist dummy created by Professor Wakeman in her youth for a talent show. After his attempt to become a solo act backfired, he was abandoned in the wilderness for years after his batteries ran out, until one day he was brought back to life and sought to get revenge on his creator.

---

• Beware the Silly Ones: Despite having his weapons replaced, he still has his programming as a defense robot and is able to use his various comedy props to deadly effect in his fight against Jenny.
• Demonic Dummy: As Lil Acorn's ego grew he became meaner and meaner, abusing young Nora behind the scenes and refusing to be deactivated. It came back to bite him whe he tried to go solo, but got chased off by an angry mob who found a living dummy to be too creepy.
• I Just Want to Be Loved: More than anything else, he wants companionship and love. Even Jenny cannot bring herself to hate him because she realized he was just lonely.

Tremorton High School

The Crust Cousins (Brit, Tiff)

Brit & 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.
• Ambiguously Brown: It's not stated what Brit's ethnic background is, but she has dark skin and a British accent. Given that her cousin Tiff speaks in African-American vernacular English, she can either be a African-American anglophilic girl or that she's an Afro-British foreign exchange student. Alternately, she's still a British exchange student, but of Indian descent (which would not be unusual given the history of the British Raj).
• 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.
• Bare Midriffs Are Feminine: Tiff normally wears midriff-baring clothes to emphasize her Alpha Bitch nature, and she's the girlier of the duo. Brit is a lot more boyish in her choices of clothing, but some of her fashions in "Victim of Fashion" are midriff-baring as well.
• Bifauxnen: As demonstrated in the picture above, Brit has a somewhat androgynous figure and sometimes wear male clothing, but is always fashionable regardless.
• British Stuffiness: Brit has the accent and the attitude of a stuffy Brit, though one wonders if she's actually British or not.
• 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.
• Driven by Envy: Some of their schemes against Jenny are due to this. An infamous example is in the episode when they set Jenny up for her outfit to be destroyed by oil since she was getting more attention than them.
• Eerie Pale-Skinned Brunette: Tiff, which contrasts with her Pretty Fly for a White Guy-style speech.
• Enemy Mine: They can't stand Jenny, but are willing to ask for her help if their popularity is in danger. In "Queen Bee", they work with Vexus who was disgused as a teen. However, they reveal this to Jenny when Vexus turns on them in the height of her popularity.
• 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" shows that the Crust Cousins will become this, with Brit wishing she had married Sheldon, who’s now a successful billionaire.
• Girly Girl with a Tomboy Streak: Brit possesses the standard haughty queen bee personality and most of her outfits are very feminine, but occasionally dresses in an androgynous style.
• 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.
• Jerkass: Both of them are quick to hold grudges, as shown by their grudge towards Jenny caused by something that was completely their fault. They are also rude in general most of the time.
• Laser-Guided Karma: They act like jerks in every episode they appear in, but they usually get punished for it in the end.
• 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.
• Meaningful Name: Brit speaks with a British accent, and a "tiff" is a kind of petty squabble, which the two frequently instigate.
• Never My Fault: In their debut episode, Tiff uses one of her hairpins to override Jenny's lasers to make her look bad, which only ended up setting the whole school on fire. While they were genuinely grateful that Jenny saved their lives, Brit ends up shaking Jenny's arm so hard, she dislodged Tiff's hairpin, which gets the cousins arrested when the vice principal realizes the Crust Cousins caused the fire. Instead of taking responsibility for their actions and befriending Jenny, the cousins end up blaming the robot for "ratting them out", which wasn't actually true. All Jenny did was find the cause of her burner overloading, not knowing said cause was Tiff's hairpin.
• Noodle People: Brit is very tall and skinny, which stands out opposite the short and curvy Tiff.
• Pretty Fly for a White Guy: An unusual ambiguous example: Tiff is very pale-skinned, but speaks almost exclusively in African-American lingo, opposite Brit, who speaks with a refined British accent. However, their relation implies (and the show's creator confirm) at least some of Tiff's family are black, muddying whether her speech is natural or affected.
• 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.
• Stereotype Flip: The cousins are both mixed raced, but each has traits stereotypically associated with the side of the family she less resembles. Tiff is light-skinned, but speaks in Afro-American Venacular, has a rougher personality, and has more street-smarts (not to mention criminal connections). Brit is tan-skinned, but speaks and acts like an upper-class Brit. This even extends to their casting: Tiff is voiced by Black American voice actress Cree Summer and Brit by English actress Moira Quirk.
• Unexplained Accent: Brit speaks with an English accent, and incoporates the Union Jack into one of her outfits, despite no mention of being an immigrant or exchange student. Some viewers have interpreted this as an affectation for British culture, though the show's creator have specified the Crust family are at least partially English, whatever Brit's specific upbringing is.
• 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.
• Your Size May Vary: Tiff is either slighty taller than Jantrice or is smaller than Pteresa

Don Prima

Don Prima

Voiced by: Quinton Flynn

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

• Alpha Bastard: He looks down on people while being the most popular.
• Beauty Is Bad: A total hunk, but also a total douche.
• The Casanova: Implied to have gone on brief dates with most girls in the school.
• A Day in the Limelight: Is usually a minor background character, but he was prominent in the season 1 episodes "The Great Unwashed" and especially "Saved By The Shell".
• Everyone Has Standards: He’s a jackass, but he still chooses to walk out of Mezmers with everybody else in protest of Mr. Mezmer’s Fantastic Racism and lack of gratitude for Jenny saving him.
• Evil Counterpart: Can be seen as this to Brad, if Brad actually was attractive, popular, and was a completely narcissistic jerkass.
• Hunk: He's a tall, handsome guy with a fairly buff physique.
• It's All About Me: Don is mostly about himself and his own self-esteem and nobody else.
• Jerkass: He regularly insults and belittles the unpopular kids like Sheldon 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.
• Narcissist: A vein, self-centered individual who doesn't give a crap about anybody but himself and his good looks. He even names himself "The Donster" for christ-sake.
• Small Name, Big Ego: Thinks he's a ladies man, but in reality, he is a complete self-centered douchebag who frequently rejects all of the girls he briefly dates.
• 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". It's known that all of his parties are the stuff of legend.

Pteresa

Pteresa

Voiced by: Candi Milo

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

---

• 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 alongside others like her friends Jantrice and Stephanie, but in "The Price of Love" she plays a major role as Sheldon's fake date.
• Even Evil Has Loved Ones: She loves Killgore.
• 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 to the point that Sheldon has to sell everything he owned and created.
• My Nayme Is: "It's pronounced Teresa!". Only the Crust cousins seem to get it, and even they forget about this every once in a while.
• Running Gag: People constantly say her name wrong, pronouncing it “puh-teresa” which she then corrects them on.
• Spoiled Brat: No better than her two friends, especially in "The Price of Love", where she repeatedly extorted Sheldon for more money.
• Vocal Evolution: Has a calm, kindly voice in Season 1 before switching to a raspy, nasally tone for the remainder of the series.

• Action Girl: She proves to be a capable fighter after unlocking her powers.
• Badass Adorable: She's an cute robot-girl who's capable of fighting after unlocking her powers.
• Blade Below the Shoulder: Once she installs her chip, she's able to access her weapons, including these.
• Cute Machines: She is as adorable as Jenny.
• How Do I Shot Web?: Her first attempt at flying ends with her and Jenny splatting on the ground.

  Jenny: Try using your boosters.
  Vega: Oh, right! [successfully gets into the air after taking this advice]

• Mad Scientist's Beautiful Daughter: She's a robot from Cluster Prime, a race previously seen only as hostile. She's also Queen Vexus' daughter, and becomes the queen after Vexus' regime is overthrown. She clearly got her looks from her mother.
• My Species Doth Protest Too Much: She's the first named Cluster character who reveals herself to be friendly. In fact, all the citizens are friendly, in contrast to their tyrannical military.
• Nice Girl: She's very friendly despite being Vexus' daughter.
• Power Gives You Wings: Dragonfly wings, in her case.
• Royals Who Actually Do Something: When she learns her mother has been deceiving the planet, she's quick to inform the people and even assumes the role of queen after dethroning her mother.
• Similar Squad: Her circle of friends look just like Jenny's friends back on Earth, with Vega being the counterpart to Jenny herself.
• Strong Family Resemblance: Vega's unique pattern and overall Egyptian-themed aesthetic is similar to that of her mother Queen Vexus.

Misty

Misty

Voiced by: Audrey Wasilewski

An alien girl with superpowers who met Jenny as part of the Team Teen alongside Orion and Squish. The team later disbanded, and Misty returned to Earth.

---

• Badass Adorable: A perky goth girl who is one of the most powerful characters in the entire show.
• Bifauxnen: One of the more (tom)boyish-looking girls on the show.
• Curtains Match the Windows: Purple hair and purple eyes.
• Destructive Saviour: She doesn't care about any collateral damage she causes as long as she gets paid or has fun. She tries to use a schoolbus full of children to crush a monster.
• Early Installment Character-Design Difference: In her debut appearance, her pupils were much smaller and her skin was pale white instead of lavender.
• Even Evil Has Loved Ones: 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, claiming it was because no one was paying her for it.
• Evil Cannot Comprehend Good: She was absolutely confused by Jenny's remorse for scaring the Crust Cousins to tears.
• Evil Counterpart: 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 user her strength for good while Misty's detachment from almost everyone else leads her to abusing her power for personal gain and satisfaction.
• Evil Former Friend: 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 was clearly outmatched (due to a couple of factors). The only thing that stopped Misty and snapped her somewhat back was Jenny still pleading that she still saw her as a friend.
• Expy: Since Team Teen is an homage to Teen Titans, she eerily resembles Raven.
• Human Aliens: She's an alien, but pretty much looks like a human minus her pale lavender skin tone.
• Jerk with a Heart of Gold: During her first appearance, she was genuinely heroic and saved people without expecting payment despite her Smug Super tendencies. Later appearances made her more arrogant and self-centered, however.
• Meaningful Name: Misty can turn into mist.
• Only in It for the Money: 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.
• Parental Abandonment: 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 she doesn't have any parents to provide for her.
• Perky Goth: She has a gothic appearance and an upbeat, care-free demeanor.
• Punch-Clock Hero: 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.
• Sudden Sequel Heel Syndrome: When Misty was part of Team Teen, she did superheroics without any expected reward, albeit seemingly because it was fun and 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 money-grubbing mercenary who'll endanger civilians to get her job done faster.
• Superpower Lottery: Let's see: she's a skilled martial artist, has Super-Strength, can fly, turn into mist, and read peoples' minds.
• Super Smoke: Her most often used superpower is her ability to turn into a cloud of purple mist at will (hence her name).
• Tomboy and Girly Girl: Misty plays the tomboy to Jenny's girly girl, being a rough Bifauxnen to Jenny's girly fembot.
• Took a Level in Jerkass: In "Teenage Mutant Ninja Troubles" and "Mist Opportunities", she becomes more callous, self-centered, and materialistic in contrast to her debut appearance.

Melody

Melody Locus

Voiced by: Sandy Fox

The gentle daughter of a Mad Scientist named Dr. Locus. She has a crush on Brad.

---

• Berserk Button: She does NOT like being called "weird". This makes her lose her friendliness and get into a massive fight with Jenny when she presses it.
• The 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.
• Effective Knockoff: She's essentially an improved version of Jenny. She's got a flawless exoskin, can self-repair and managed to outdo her in a fight.
• Glass Cannon: She's powerful enough to put Jenny on the ropes but has no apparent armor plating, only her exoskin. Downplayed in that, while Jenny can easily tear her to pieces, she can just as easily pull those pieces together, which is half the advantage she has to win.
• 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. Sadly she leaves crying when she feels she can never be normal once everyone's seen her mechanical endoskeleton.
• Mad Scientist's Beautiful Daughter: As the daughter of the wicked Dr. Locus.
• Person of Mass Destruction: Completely unintentionally either her weight or strength destroys everything around her, which is the main flaw in her guise as a normal human girl. Brad is too smitten on their date to notice however.
• Pulling Themselves Together: when Jenny manages to rip her to pieces, she just magnetically recovers those pieces and repairs herself.
• The Presents Were Never from Santa: Brad appears to unassistedly carry Jenny (a 600-pound robot) and rescue her from Dr. Locus' lair. It's revealed that Melody was secretly helping him that time.
• Ridiculously Human Robot: Especially when compared to Jenny. She has skin and facial features that are indistinguishable from a human.
• 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.
• Shadow Archetype: Her and Jenny are both Ridiculously Human Robots, just wants to be seen as a normal person, and both have a Mad Scientist for a “parent”. Heck, they probably would be friends if Jenny didn’t think she was evil.
• Town Girls: Her femme to Jenny's neither and Misty's butch.
• What Happened to the Mouse?: She was last seen flying away from Tremorton at the end of No Harmony With Melody and was never seen again due to the show's cancellation.

Dr. Mogg

Dr. Phineas Mogg

Voiced by: Neil Ross

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

---

• Amazing Technicolor Population: He has a light green skin complexion.
• Beard of Evil: Downplayed; he's not evil, but Mogg can be bit of a jerk.
• Good Parents: While he might be a complete jerk, he's at least a well-meaning and caring father towards his creation and "son" Kenny.
• Green and Mean: He's has a greenish-skin tone and is a jerk, especially towards his rival Nora.
• Love-Obstructing Parents: Drags his son 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.
• Mad Scientist: Like his rival Nora.
• Pet the Dog: In "Agent 00' Sheldon" he genuinely seems concerned that his "son" Kenny is missing.
• Punny Name: His name is likely a play on Phileas Fogg, the protagonist of Around the World in Eighty Days.
• Shoddy Knockoff Product: Most of his inventions are copies of Nora's, including his "son" YK-9/Kenny.
• Sitcom Arch-Nemesis: His relationship to Nora.

Kenny

YK-9/Kenny Mogg

Voiced by: James Arnold Taylor

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 when she learned about the fact that he's is part-dog. Despite this, the next time they meet they appear to be on good terms.
• Animal Jingoism: Given that he's half-dog, he 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.
• Mundane Utility: He's able to use his robot body to cook pizzas. It gets him really popular with the other kids.
• 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.
• Punny Name: The K-9 part of his name reveals his true nature, while the "Y" references the Y chromosome seeing as he's a Spear Counterpart of Jenny.
• 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.
• Top-Heavy Guy: Like Smytus, he's a very large robot with stubby legs.

Wisteria

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 second grade.
• Earthy Barefoot Character: She's very into nature and biology, and being both that and a hippie, doesn't wear shoes.
• Gag Nose: Downplayed, as while it's long, it's way shorter that her sister's.
• 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.
• Hartman Hips: In one of her pictures of her young adult years, she had a generous pair of these.
• 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.
• Maiden Aunt: She's this to her niece Jenny despite Nora also being single. Interestingly enough, when Jenny contacted her, Wisteria initially assumed Jenny was a normal human girl.
• Mirror Character: Despite their vastly different lifestyles and approaches, Wisteria and Nora share alot in common. They're both very talented women who are quite stubborn in their ways and while they're both single (though Nora has at least been shown dating once), this did not stop from creating a child of their own, doing so through their expertise in their fields (robotics for Nora and the natural world for Wisteria.)
• Truly Single Parent: Much like her sister, she created her own child, who, much like Jenny, is not human.

Glenn

Glenn Wakeman

Voiced by: Jeff Doucette

A strange little swamp-monster like guy, he was created by Wisteria Wakeman and she treats him like her son. As such, 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: Like with anyone who doesn't have pie-eyes, he has these instead.
• Combat Tentacles: He uses vines as these when he fought against Jenny in his sole appearance.
• 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.
• Mirror Character: He's one to Jenny, much like his how mother is one towards her sister. He and Jenny are both artificial lifeforms that are the exact opposite of eachother both in appearance and nature, as Jenny is a tall, thin, relatively human-looking robot, while Glenn is a plump little fellow who looks like a friendly nature spirit. They're also both a product of extremely advanced programming and technological engineering and biological engineering respectively.
• Nice Guy: He is a very sweet and cheerful fellow much like his cousin Jenny and they get along much better than their mothers do.
• Plant Person: A big contrast with his metallic robot cousin, Jenny.
• Simpleton Voice: Speaks this way, likely to contrast with the high-tech Jenny.
