Nightmare Fuel / My Life as a Teenage Robot

Not all is cutesy in this life...

  • At the beginning of the first episode "It Came from Next Door", Tuck walks into Jenny's house to retrieve a baseball. Much of the house looks dilapidated, with what looks like the remains of a robot leaking oil. This is never brought up again.
  • When Tuck envisions the Planet of the Bikers, there's a sudden art shift in the character design, giving it a more-than-creepy look. The fact that the evil bikers' designs are based on the work of Rob Zombie doesn't help much, either.
    • Although Tammy doesn't have an scary appearance initially, her monstrous mouth and tongue (a Shout-Out to Alien) can catch people off guard in "Ball in Chain". Also, there is the concept of being a slave in marriage; trying to get out of it involves the groom being eaten by the bride. It is said to be the tradition on the Space Bikers' planet.
  • Gigawatt is certainly unsettling...mostly because he's one of the few villains that could effortlessly curbstomp Jenny time and time again.
  • When Vexus has her Villainous Breakdown. Both that and her obsession with Jenny and her various disguises and Evil Plans.
  • The Exo-Skin. It was designed by Nora Wakeman to allow Jenny to pass as a normal human girl, but turns out to be a G-rated version of Venom.
    • The way the Exo-Skin slithers up to Jenny like a snake in the middle of the night — and its appearance in the moonlight — still gives many fans the shivers. (So much that the scene became the header image for this page.)
    • When Jenny first tries out the new skin, it latches itself onto her body and slowly crawls over her face. She tries to tell Nora Wakeman that there's something wrong, but Wakeman ignores her as she crawls back into the shadows, struggling and crying out.
    • Worse, unlike most of the show's villains, the Exo-Skin isn't defeated: at the end of the episode, after the skin has supposedly been "deactivated" by Jenny pouring milkshake on herself, Brad's cranky, grumpy old boss at the diner gets attacked; after his customers desert him, he begs for them to come back, insisting that he's seen the error in his ways...just as the skin's sensors latch onto him. The exo-skin CHOMPS down on him, laughing menacingly, as the screen goes black.
      • Even worse? The Exo-Skin is never seen or heard from again after that episode; as far as the viewers know, it's still out there. Nothing Is Scarier, indeed.
  • This bit from "The Wonderful World of Wizzly":
    Jenny: Go on, little robots! Be free!
    Robot Raccoon: But where are we supposed to go?
    (Jenny twists her head 180 degrees revealing a big, blanked-eyed Death Glare)
    Jenny: (monotone) I free.
  • "Armagedroid". The first fight against him and seeing him tear Jenny apart. Plus the fact that, although not explicitly stated, it appears that he came dangerously close to killing her. There's also the fact that he was built by Wakeman, essentially making him Jenny's brother.
    • In a similar sense, "Enclosure of Doom". Just the fact that Jenny managed to talk Armagedroid into destroying himself.
      • How it's done it also unnerving: first you have him tearing into himself, basically causing a robotic disembowelment, and ripping out as much of his insides as possible, and then you have him activating his self-destruct.
      • It's worth pointing out that he was still in town when he did this.
  • Lil'Acorn. Everything about him, from his backstory to the fact that he almost succeeds with his plan.
  • The fact that Larry-3000 from TimeSquad, appears to be dismantled, in his cameo appearance of "It Came from Next Door", as if someone murdered/tortured him.
  • Vexus' plan to convert Jenny in "Hostile Makeover", where a bug she plants in Jenny's system causes her to hideously mutate into a violent, supersized robot. Jenny's fear as the changes escalate is unmistakable. She gets better though.
  • In "Mama Drama" Jenny fears that her mom's new date is actually a villain. And the end, she starts chasing him, pins him to a wall and attempts to cut him in half with a buzzsaw to his horror. The only reason she doesn't go through with it is because Dr. Wakeman shuts her down. It turns out that the man is completely innocent, meaning Jenny almost brutally murdered a man in public based on a misunderstanding.
  • In the Christmas special, Jenny spends a year Brainwashed and Crazy so the villain of the special can destroy holidays. When she snaps out of it, she's missing that entire frame of time and was blatantly terrified that all her friends and her own mother want to shut her down permanently over something she doesn't remember doing and didn't even do willingly.
  • Melody's robotic form in her last appearance. Holy shit, she looks so... alien like and of course her enraged screams at Jenny.
    • I AM A NORMAL GIRL! -full blown robotic-demon form- I'M NOOOOOOOOORMALLL!!!!!!!
