These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: My Life as a Teenage Robot
Alternate Character Interpretation: The Biker aliens run a school in their home planet. They do everything to benefit their society. On weekends, they take their stress out on Earth.
Crossover: Jenny is often drawn with/as Hatsune Miku, due to both characters being virtual and wearing teal pigtails and short skirts.
Ear Worm: "Oh, Happy Noontime Funtime Song! We love to sing it all day long..."
"This is the song that goes on forever 'cause it doesn't ever end, and we will finish singing it never 'cause here we go again"
Ensemble Darkhorse: Vega (The Special), Misty (3 episodes), and Melody (2 episodes) have gotten a huge amount of fan art.
You will ALL bow down before KILLGORE!
Armageddroid is rather popular as well.
The show itself to an extent. It isn't as much as a darkhorse as Invader Zim or Danny Phantom, but it has a fair amount of fans.
Fan-Preferred Couple: Brad/Jenny, compared to the one-sided and eventually-would-have-been-canon Sheldon/Jenny.
Genius Bonus: In one episode, Jenny finally gets a date with a boy who has a fear of technology. The movie they choose to see? Modern Times.
Hilarious in Hindsight: "Unlicensed Flying Object" features an alien threatening to swat Jenny, Brad and Tuck with a glorified electric flyswatter. Two years later, real electric flyswatters would gain popularity.
Les Yay: Jenny and Vexus' daughter Vega in the finale. Also Jenny and Misty.
Moe: Jenny, whose insecurities and innocence can be quite endearing.
Ugly Cute: Sheldon looks like your standard geek but he's a very kind admirer.
