Characters: My Life as a Teenage Robot
open/close all folders
"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 "16-year-old robot" to which the title refers, a state-of-the-art sentient gynoid automaton created by Dr. Noreen Wakeman five years prior to the series, though she was designed as a 16-year-old girl. Though XJ-9 was designed to be Earth's protector, armed to the teeth with a wide range of weapons, devices, and transformations, she desires to live the life of a normal teenager and often makes this desire quite apparent to her friends and creator.
- Action Girl
- Adorkable: When she gets acquainted with the real world for the first time.
- All of the Other Reindeer: No matter what she does, she will always somehow end back up as the school freak.
- Badass Adorable and Cute Bruiser
- Balloon Belly: She inflated more than once, despite being made of metal.
- Bare Your Midriff: Her chassis design is meant to mimic this, complete with a large exposed screw for 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.
- Bratty Teenage Daughter: To Nora sometimes.
- Comically Missing the Point: She takes Tucker's literal advice and eats a bunch of cotton balls to experience feels.
- Cool Loser: It's hinted that if the school weren't under the tyrannical reign of two Alpha Bitches, Jenny wouldn't be a reject at all.
- Cute Machine
- Deadpan Snarker: Started developing into this by season two.
- Do-Anything Robot: Her arsenal is downright Hammerspacey.
- Does Not Know Her Own Strength: Sometimes, depending on if it's funny at the moment.
- Fem Bot
- Genki Girl
- Girlish Pigtails
- The Heroine
- I Just Want to Be Normal: Combined with I Just Want to Have Friends: Being a superpowered robot wouldn't be so hard for her if there were more bots as advanced as her.
- Jerk with a Heart of Gold/Nice Girl: She often shifts between these, depending on whether the episode is making liberal use of Surrounded by Idiots.
- Jetpack: Not so much as one as a flying robot, as she has rockets as part of her body.
- Magic Skirt: Justified, that skirt's made out of metal.
- Pinocchio Syndrome: Averted - she's perfectly fine with being a robot, but wants acceptance and assimilation... which sometimes means playing the trope straight.
- Red-Headed Heroine: Once had red body paint, and her makeshift human form is a redhead.
- Ridiculously Human Robot
- Robot Girl
- Robot Hair: She sports a pair of metal pigtails. They house two of her jet thrusters.
- Statuesque Stunner: She's 6 1/2 feet tall and really cute to boot.
- Super Strength: "The strength of a million-and-seventy men," if the theme song is to be taken literally. note
- Surprisingly Good Japanese: Helped by the fact that her VA Janice Kawaye is a Japanese-American who speaks the language fluently.
- Telescoping Robot: She provides the trope picture.
- Wake Up, Go to School, Save the World
- Younger than She Looks: Technically has been alive for about 5 years, but has all the mentality of a teenage girl... usually.
- However the fact that Jenny being physically five years old, has had a drawback of being forced to be in Kindergarden for the majority of the episode "I was a Preschool Dropout".
- You Gotta Have Blue Hair: Most of her body is baby-blue metal, jet-powered pigtails included.

Sheldon Lee/Silver Shell
Jenny's self-proclaimed romantic admirer.

- Adorkable: He is quite geeky, but has likeable traits to him.
- Asian and Nerdy: He's apparently half Asian.
- Badass Normal: In "Agent Double-0 Sheldon".
- 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. It depends on the writer.
- Crouching Moron, Hidden Badass: He was a space pirate for decades. And a secret agent.
- Distressed Dude
- Dogged Nice Guy
- Dude, Where's My Respect?: It's not that he can't ever get any respect, but he has to work much harder for it.

- Large Ham: As the Silver Shell.
- Older Than He Looks/Really 700 Years Old: After the episode "Good Old Sheldon" he's only physically 15, but now officially 105 years old. Holy cow.
- Post-Kiss Catatonia: In the Christmas episode, Jenny gives him a peck on the cheek and he is frozen in position then slowly and rigidly tumbles down the stairs.
- Averted in "Double-0 Sheldon", were she once again gives him a peck on the cheek, and merely responds with a happy smile.
- Rescue Romance: Sheldon meets and falls hard for Jenny after she saves him from some bullies in shop class in the episode he's intoduced in.
- Robosexual: "Twin-manifold access ports? Ohh, baby!"
- Single-Target Sexuality: Jenny-sexual.
- Stalker with a Crush: In his introduction episode he was definitively this, but in later episodes he is more friendly and helpful towards Jenny.
- Took a Level in Badass: In "Agent Double-O Sheldon".

("Around The World in 50 Pieces")
The tyrannical queen of the Cluster who constantly tries to get Jenny to go with her to her homeworld of Cluster Prime through immoral means.
A large green robot from the Cluster who seems to have ties to its military division.
- Broke Your Arm Punching Out Cthulhu: Even after he successfully takes over Earth with the Cluster, he winds up without a lower body. Krackus had to build him a few replacements out of trash.
- I Just Want to Have Friends: Hinted at. He perks up quite a lot when he's complimented by the humans, and he has to remind his minions to laugh with him after he makes a short speech.
- Ineffectual Sympathetic Villain: Shares this trope with Vexus and Krackus in Season 3.
- Large Ham: When making his entrance.
- Paper-Thin Disguise: He puts on a wig and tries to pass of as Smytlana, a Ukrainian supermodel, after his attempt to break into a fashion designer's private boutique goes awry because the secretary called him fat. After a short while of being complimented, he falls for the disguise himself.
- Superhero Movie Villains Die: In the Big Damn Movie, Smytus' last resort is a self-destruct mechanism he had installed on his forearm.
A senile, older robot who often bungles his experiments and forgets where he is all the time. His inventions almost never last for very long, but he's not one to give up easily.
A small, adorable wind up robot from a toyline, Killgore somehow manages to attain sentience and decides to fulfill its purpose as a villain by joining the cluster. Things don't always go as planned for him, however.
A citizen of Cluster Prime who seems wholly nonconfrontational. She is Queen Vexus' daughter, and after the movie, the current Queen of the Cluster.

The Crust Cousins, Brit and Tiff
Voiced by: Cree Summer (Brit), Moira Quick (Tiff)
The antagonists of Jenny's life in high school, they seek to humiliate her at every turn.
- Alpha Bitch
- Ambiguously Brown: Brit
- Bare Your Midriff: Tiff's normal costume. Some of Brit's fashions in "Victim of Fashion" do it at well.
- 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.
- The Quisling: Sided with the Cluster after they invaded Earth in "Escape from Cluster Prime".
- Too Dumb to Live: More than one of their schemes have terribly backfired.
- Unlimited Wardrobe
