- Adorably Precocious Child
- All-Loving Hero: Even though he has his jerk moments, Ned Bigby does not hate anybody, and he always gives advice to those in trouble, whether he or she is a student or a teacher. He hates letting people down so much that his bad habit in Guide to: Bad Habits was saying yes to everyone. This trope is Averted at times like when he was the Revenger in one episode, but at end of that same episode, he realizes that revenge is wrong.
- Attention Deficit... Ooh, Shiny!: Has trouble concentrating, which does get him in trouble sometimes (okay, a lot!) This is also why he had trouble focusing on his project in Guide to: Procrastination until three days before it was due.

Jennifer "Moze" Mosely
- Portrayed by: Lindsey Shaw
"Whenever I give you advice - and it's great advice, created by the superior girl mind - you ignore it and go to Gordy for a man-plan!"The sensible and snarky, as well as the aggressive, competitive and athletic, one of the main trio, who has the most common sense of the group and has never really been "one of the girls."
- Academic Athlete: She's captain of the volleyball team, holds many school athletic records (including the one for holding the most records), and is also a straight-A student.

- Action Girl
- Badass Adorable: She's a lot stronger than she looks.

- Batman Gambit: Pulls one after finding out Ned and Cookie switched into her elective after she explained that she wanted to take an electice without them. She goes to the woodshop class, knowing that they're following her, then when they're trying to switch into that class, she goes to life science and switches to that class.
- The Big Girl: Moze is easily the strongest of the trio and, before Cookie hit his growth spurt, was the tallest as well. She's beaten Ned and Cookie up many times, shoved Ned against a locker during her "anger" phase of the Five Stages of Grief when she lost her backpack, beat Loomer up after he gave Ned a huge wedgie in the third grade and, more recently, flipped him in Guide to: Gym, was able to send Loomer and his posse running just by threatening to beat them up, and was able to beat all the boys on Polk's wrestling team in wrestling practice without breaking a sweat.

- Bully Hunter: On occasion.

- Cool Loser: Though she's actually quite popular.
- Cute Bruiser: She may be cute looking but has absolutely no problem with beating the stuffing out of anyone who pisses her off.Moze: *to Loomer and his gang* If there were ever a time to beat someone up for no reason, it would be now.Loomer, Crony, and Buzz: *run away*
- Deadpan Snarker: Every other sentence she utters is sarcastic.
- Double Standard: Abuse, Female on Male: She punches and beats up Ned and Cookie regularly. She sort of gets called out on her bullying ways in Guide to: Bullies, but she doesn't actually change anything or do anything about them after the episode.
- Dude Magnet: She has attracted the attention of many guys, such as Seth, Loomer, Faymen, Jock Goldman, and, of course, Ned.

- I Just Want to Have Friends: Her goal in the first two seasons is to get a best female friend.

- One Steve Limit: In-Universe. Ned gave her the nickname of Moze in Kindergarten because there were three Jennifers in the class.

- Tsundere: May qualify as a Type A.
- Vitriolic Best Buds: She flings insults and punches at Ned and Cookie, but it's obvious she sees them as her closest friends.

- Attractive Bent-Gender: In-Universe, as "Simone"
- Beware the Nice Ones: When he lost his temper in Guide to: Dodgeball after Loomer's dodgeball damaged his videocamera helmet, he threw the dodgeball so hard it knocked Crony out.

- Corrupt the Cutie: A mild example in Guide to: Dodgeball, when Loomer convinces him to give in to his anger and join the "dark side" of the dodgeball court. He gets better, though.Ned: Cookie, you're on Loomer's team?!Cookie: *in a robotic voice thanks to his helmet* The power of the dark side is strong.
- Nearly happened because of the influence of the Killer Bees in Guide to: Best Friends.

- In Touch with His Feminine Side: He likes braiding hair, desperately wants to be a cheerleader, loves girly books, likes getting his nails done, got so attached to the baby doll he and Ned had to take care of in life science class that he took it home for the holidays so that it wouldn't feel lonely, and has worn skirts more often than Moze (though this is in part because Moze hates skirts).
- Jerk with a Heart of Gold: He tends to be self-centered and is almost constantly trying to find new ways to con others or avoid doing work, but he's a good guy at his core.

- Masculine Girl, Feminine Boy: Feminine Boy to Moze's Masculine Girl. (One of two)
- The McCoy: To Moze's The Spock and Ned's The Kirk.

In addition to giving us the page quote, she scares off any female except Moze who get's remotely close to Ned until he fakes dating Moze just to drive her off.Ned: Missy, I've found someone else.Missy: You're so cute when you say things that will get you and whoever you're talking about severely injured.

- Almighty Janitor
- Breakout Character
- Bunny-Ears Lawyer: Subverted/inverted in "The New Kid," where another janitor competes for Gordy's position. Gordy keeps the job... not because of his competence (the other janitor was in fact a lot better), but because he was shown to care more about the students than his competition did.

- Batman Gambit: In one episode when he was having a test coming up, he scolded Ned for his notebook and told him about the "Golden Notebook" that belonged to a former ace student, saying that if his was anything like it, he may have a chance of passing the test. Ned switched the notebook with a replica and aced the test. As he was putting it back, Sweeney caught Ned and revealed that it was him that wrote the notebook.Sweeney: I just made up that story because I learned a long time ago that some students need to be tricked in order to learn.
Ned: But why didn't you just loan it to me?
Sweeney: Because then it would've been just another boring assignment for you to ignore. (Ned nods in agreement) And you wouldn't have gotten an A on the test. And now, caramel covered apples with nuts to celebrate a job well-done.
- He has a villanous one in another episode. When the students were planning to do the "atomic flush" by flushing all the toilets in the school at once, therby hopping the entire school off the ground. Knowing that every single toilet would haveto be flushed, he boarded himself inside the teachers' lounge bathroom, ensuring that it wouldn't happen. Though he still helped accomplisb it in the end.

Whatever happened to her was so traumatic that she no longer leaves home. The most she does is communicate with people through a webcam.
- Sadist Teacher: At first, but it turns out it was a sort of Jerkass Fašade so she wouldn't be scared of her students from that year on. Ironically, it had the opposite effect until she loosened up.
- Portrayed by: Jim J. Bullock

- Demoted to Extra: After Season 1, where he was a regular who seemed to fill the Reasonable Authority Figure role. He was apparently Put on a Bus in Season 2 (although it surprisingly wasn't mentioned at all), but this was lampshaded upon his brief return for a couple episodes of Season 3.
