Characters: My Life as a Teenage Robot
"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.
- Amazonian Beauty: Though you can't tell from the character designs, XJ-9 is 6 1/2 feet tall, according to Professor Wakeman's specs.
- 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
- 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.
- 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.

- Asian and Nerdy: He's apparently half Asian.
- Badass Normal: In "Agent Double-0 Sheldon".

It depends on the writer.
- Crouching Moron, Hidden Badass: He was a space pirate for decades. And a secret agent.

- 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.

- 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.
