- Breakout Character: The most well known character from early Degrassi.
- Break the Cutie / Break the Haughty: When he failed grade eight in Degrassi Junior High and again when he's diagnosed with dysgraphia in high school and is placed in a special education class.
- The Bully: A very moderate version of this in season 1 (to Arthur, Yick, Melanie), but completely averted afterwards.
- Casanova Wannabe: He tries to get with everyone and fails before Caitlin takes an interest.
- Catchphrase: He always says "Trust me" when he's trying to convince his friends to do something stupid. In one episode, he says it so much that that's the title! This is finally lampshaded in the series finale when Joey is worried about his date with Caitlin.Wheels: Relax, everything will be fine. Trust me.Joey: Don't say that! Every time we say that it's a disaster!
- Character Development: He's introduced in season 1 as an obnoxious,immature, egotistical jerk. While still keeping these traits, he becomes a more likable and good person as the seasons went on.

- Jerk with a Heart of Gold: Liz said it best: "Joey's okay. He just doesn't think sometimes."

Played by Nicole Stoffman
- Alpha Bitch: Although a much more vulnerable one.
- Be a Whore to Get Your Man: The only way she feels she can attract boys is by dressing and acting like a total slut.
- Big Brother Bully: A female example with the way she treats her brother Arthur.
- Date Rape Averted: Avoided this from an older soap star with a horrible mullet.
- Darker and Edgier: Her character after the first season. Her parents divorce and her lack of self worth leads her to consider suicide. She gets better.
- '80s Hair: Her hair might be the most dated element of the show.
- Expy: She was the first Degrassi girl to change into more revealing clothing in the girls' washroom beofre class, a trick later used by Manny Santos and Alli Bhandari.
- Funetik Aksent: She spells her name Kaye. K-A-Y-E. Calling her Kobalawski is just a Berserk Button.
- I Just Want to Be Special: At her core, this is pretty much how she feels.

Played by Duncan Waugh
- A-Cup Angst: G-rated version: He hates being short.
- The Artifact: Once Stephanie left, his character moved into the background. By Degrassi High, he was Demoted to Extra. Ironically this would also happen to Ashley and her brother Toby in Degrassi: The Next Generation. Their characters were very much based on Steph and Arthur.
- Demoted to Extra: Along with Joey and Steph, he and Yick were the stars of Degrassi Junior High. But by Degrassi High, he is relegated to more of a background character,
- Dogged Nice Guy: He has a major crush on Caitlin, but she makes it clear she is not interested. Other than that the poor guy gets no other romantic subplot. Which is saying something for Degrassi.
- Real Life Writes the Plot: He was suppose to be part of a bullying plot during Degrassi High. But the actor had grown so large that it wasn't believable.
- Two Lines, No Waiting: Arthur and Yick were usually part the B-plot in every episode during Degrassi Junior High.
Played by Andy Chambers

- Put on a Bus to Hell: After his accident.
- The Bus Came Back: He went to visit Spike for the last time in DH, the year after the accident who left him mentally disabled.
- He seemed to be far higher-functioning in DH (when he was receiving intensive outpatient therapy while living at home with his family) than in TNG (after he had been warehoused in an institution his entire adult life).
- Teen Pregnancy: Most of his plot deals with the problems he faces as a teenage dad. It ends after his drugged induced accident.
Played by Rebecca Haines
- All Girls Want Bad Boys: She went from disliking Rick to developing a crush on him.
- Domestic Abuser: Her boyfriend Scott in Degrassi High. While she could be a major Jerkass, this pushed her into The Woobie territory.

Played by Craig Driscoll
- Abusive Parents: His abusive father.
- All Girls Want Bad Boys: Caitlin and ultimately Kathleen.

Christine "Spike" Nelson
Played by Amanda Stepto
- Ascended Extra: Spike was only present in two episodes in season 1. Later she got a bigger role thanks to her Teen Pregnancy storyline.
- Awesome Mc Cool Name: It's never mentioned how she got the nickname Spike. Most people assume it's the hair, though.
- Open-Minded Parent: Her mom was surprisingly accepting of her pregnancy at 14. Although this wasn't exactly portrayed as a good thing.
- Perky Goth: While more punk than goth, her appearence belied what a polite and sweet girl she was.
- Prom Baby: Went into labor during her prom.
- Spiky Hair: Where her nickname comes from.
- Teen Pregnancy: With Emma, future quasi-protagonist of Degrassi: The Next Generation.
- Tsundere: To Shane. More "tsun" though.
Played by Irene Courakos
- Ascended Extra: Sometimes in season 1, you can see her in the background but she didn't have a real part until season 2.

- Clingy Jealous Girl: Constantly believes her relationship with Simon to be on the verge of implosion.
- The Ditz: To go along with Simon to form a Ditz Couple.
- Happily Married: The Movie ends with Simon and Alexa's wedding. As of the early seasons of TNG, they're still married.

- Single Girl Seeks Most Popular Guy: And Simon actually picked her over Alpha Bitch Stephanie.
Played by Cathy Keenan
- Animal Wrongs Group: Hates Caitlin because she uses medicine tested on chimps for her seizures.
- The Quincy Punk: Averted. Although she has the look and attitude, she cares about issues like abortion and animal rights.
- Soap Box Sadie: Anti-abortion and pro animal rights. She is one of the few characters on television who is portrayed as pro-life, but not for religious reasons. She abhors abortion because her mother nearly aborted her.
- Tsundere: To Joey early on, but after he tries to put the moves on her, goes to constant "tsun".
Played by Stacie Mistysyn
- Expy: The same basic character as Mystysyn's in The Kids of Degrassi Street (Lisa).
- He Who Fights Monsters: Tries to call attention to how the parents are treating Spike's pregnancy. She ends up hurting Spike.
- Ice Queen: Her portrayal after dumping Joey for Claude in Degrassi High. Joey even calls her an "Ice Maiden" at one point.
- I Can Change My Beloved: She sometimes sees boys as projects to fix. Rick and Joey call her out on this.
- Soapbox Sadie: Before Emma, there was Caitlin. Most of her plots revolved around her and some cause.
- Skunk Stripe: Sort of; he hair isn't actually black, but she has medium to dark brown hair, and during season 3 of DJH, and the first season of DH, she had a blond wave in it.
- Star-Crossed Lovers: With Joey. Even though they are madly in love, no matter how hard they try, it never seems to work.
Archibald "Snake" Simpson
Played by Stefan Brogren
- Awesome Mc Cool Name: Snake. We never find out how he got the name.
- Chick Magnet: He has many girls crushing on him in both DJH and DH (Melanie, Spike, Michelle, Amy, Allison). Subverted in The Movie where, for some reason, he was unable to get any girl and even made fun of because of this.
- Cool Loser: In The Movie, he becomes a full fledged Butt Monkey.
- Foreshadowing: In his very first appearance, running for student council against Stephanie, we see him standing on the steps of the school talking about what he'd change if he were in charge. Almost certainly nobody in 1987 knew what his being on the show would lead to, but the "..you won't recognize this school at all" scene at the end of The Boiling Point might be a deliberate Call Back.
- Heroic B.S.O.D.: He is, unfortunately, the one to discover Claude's body in the bathroom. Though he bravely reports it, he is still very traumatized by it and drops out of school for a week or two to recover.
Played by David Armin-Parcells
- Boom, Headshot: though we don't actually see it, Snake mentions that upon discovering Claude's body, only half of his face was left.

- Dirty Coward: He doesn't even bother to help Caitlin when she's about to be caught by the police after spray painting a nuke building factory.
- Driven to Suicide: You Should Know This Already.
- Emo Teen: An over the top 80s version.
- He Who Fights Monsters: "Hey Caitlin! I have a great idea for a date. Let's go spray paint slogans on a nuclear weapon parts making facility! And then I'll run away when I might get caught, leaving you out to dry!"
- It Is Pronounced Tro PAY: His name is pronounced as "Clohd" (as in, the word "oh"), NOT as "Clawd", as would normally be.
Derek "Wheels" Wheeler
Played by Neil Hope
- And Then John Was a Zombie: School's Out! features a big one.
- Be Careful What You Wish For: He has issues with his adoptive parents, and then they die.
- Break the Cutie: And how. He went from a fun loving and all around good guy (in the first 2 seasons of Degrassi Junior High) to a selfish, destructive jerk after his parents' death. And he only got worse in Degrassi High, to the point that even his best friends couldn't stand him anymore and his grandparents kicked him out of the house. Taken Up to Eleven in School's Out where other than a Jerk Ass he became also Drunk Driver and a murderer.
- Catch Phrase: "My parents are dead."
- Cerebus Syndrome: In fact, the guy who kills his parents could be considered a full-blown Knight of Cerebus.
- Informed Attractiveness: Stephanie's belief that Wheels is the sexiest boy at Degrassi Junior High perplexed Albert of The Agony Booth. And probably everyone else.
- Laser-Guided Karma: School's Out ends with him in jail.
- Never My Fault: Blames all his bad behavior on the death of his parents. Wheels' inability to accept culpability angers and disgusts Snake who refuses to forgive him for twelve years.
- Parental Abandonment: His parents are dead.
- Shota Con: He hitchhikes to see his real father. Along the way..."Don't worry, Derek. It'll feel good."
- Took a Level in Jerkass: Started very slowly after his parents died. He went full JerkAss in Degrassi High, but seemed to get better near the end. Only to have it horribly subverted in School's Out.
Played by Siluck Saysanasy
- A-Cup Angst: G-rated version: He hates being short.
- Asian and Nerdy: But not too nerdy; he is an athlete, after all.
- Demoted to Extra: No longer a cute kid, he find himself Out of Focus during Degrassi High.
- Hormone-Addled Teenager: He has dreams where he, you know, kinda, "leaks".
- Pass Fail: Though from Laos, he tries to pass as being from the Chinese upper class in order to make his family history "interesting".
- Took a Level in Jerkass: He turns into a total jerk in Degrassi High. It coincides right with the breakup of the Arthur and Yick bromance.
Played by Darrin Brown
- Arch-Enemy: To Joey, but they reconcile after Dwayne discovers he is HIV-positive and Joey agrees to keep his secret.
- Ascended Extra | Chekhov's Gunman: Is a seemingly one-off character appearing in a couple episodes of DJH, only to get full blow main character status in Degrassi High.
- Odd Friendship: He started one with Joey in the second season of Degrassi High.
- Terrible Trio: Tabby, Nick, and Dwayne. The least threatening trio of bullies ever.
- Very Special Episode: His entire plot took over season two of Degrassi High. It was the early 90s and AIDS was just starting to be talked about.

- Put on a Bus: Her last appearance is during the first season of DH, and after that it's said that she's off adventuring with her dad after her brush with Leukemia.

- Makeover Montage: Lucy gives her one and it makes her look much worse.
- Tomboy and Girly Girl: She's the tomboy to Lucy and most of her friends.
Played by John Ioannou
