The Ace: Especially in season 1, when she was the only one who was allowed to solve everyone's problems and be perfect at everything. Though this was toned down later where she's more of a Jack-of-All-Trades.
Beware the Nice Ones: Zoey is as loyal and kind-hearted as a friend and girl in general could be, but if you bully her friends or little brother, try to dictate who she can and can't be friends with, rig competitions, or say girls can't do the same things guys can, she'll either chew you out or make sure you get yours.
Big Sister Instinct: She's very protective of Dustin. In one episode, when she found out that her brother was being bullied into doing someone else's homework, her first response was to confront the bully.
Book Smart: Apparently all her friends need her help to study for the exams. Though this was only shown in the episode Little Beach Party.
Character Tics: Zoey has a few subtle ones. Whenever she's mad, she puts her hands on her hips and when she's semi-reluctantly admitting something, she tends to roll her eyes. Zoey also likes to show affection to Chase by ruffling his hair.
Dude Magnet: Zig-Zagging Trope. She attracts boys but not a lot more than pretty much any female lead in most similar shows. On occasion, it's even subverted. There's one episode when Zoey is bartering with a guy for a favor and he asks a date in return: Zoey assumes he wants a date with her, but it turns out he's after her friend Nicole.
Everyone Loves Blondes: She's blonde and one of the most popular students, and Chase falls for her at first sight. Also Played with, because her brunette friend Lola gets just as much attention from the boys, if not more so.
Fashion Designer: She aspires to be one, and she often designs, customize and makes clothing.
Girly Girl with a Tomboy Streak: She's a very fashionable and feminine girl with girly interests, however she's still Zoey, so the writers made her good at almost everything, including sports.
Go-Getter Girl: Zoey gets good grades, takes part in many school activities, and she's a supportive mother figure not only to her friends, but willing to help anyone in need. In the last episode of season 1, she was tutoring all her friends and other students in different subjects before an important exam.
The Heart: She is the mediator and the voice of reason in her group.
Jack-of-All-Trades: She's good at everything, but rarely the best. She's the best at dancing, but not at acting (Lola), singing (Michael), sports (Dana/Logan) or grades (Nicole/Quinn). She's popular with boys, but it's stated that Lola is the hottest girl in school.
Nice Girl: Always willing to help her friends and other students, and she's a nice sister to Dustin.
Not So Above It All: There are times when she can be just as immature and rude as Logan, best shown in Election.
Oblivious to Love: Despite multiple attempts by Chase to tell her his feelings. It even gets to the point where a random girl (pulled aside by Lola) can tell that Chase likes Zoey, but Zoey cannot tell.
Lola: Ginny, could you come here a minute?
Ginny: What's up?
Lola: 'Blank' is in love with Zoey. Fill in the blank.
Ginny:(as though it were the most obvious answer in the world) Chase.
Lola: Thanks for playing.
However, as of Sep. 2015 it is revealed that since the time capsule episode she is well aware of his feelings and is reciprocating inside.
Off Screen Moment Of Awesome: In the 3rd season episode premier "Surprise", it's revealed Zoey worked a summer job as a pool lifeguard where she saved an elderly lady from drowning by successfully performing CPR at 15 years of age.
Only Sane Woman: Especially in season 1, when her two roommates, Nicole and Dana, were always fighting. Overall, she is the most levelheaded in the group, though Chase is a close second (but unlike Zoey, he's not without his quirks).
Renaissance Man: While most of her friends have a talent in just one area, Zoey excels at all of them. She's one of the best students, has athletic skills, leadership skills, is good at singing, acting, dancing, and a skilled Fashion Designer. Whatever sport or activity is the main focus of the episode, she will be great at it. Deconstructed in "Wrestling", where she's quite skilled as a fighter (especially for a girl), but still unable to beat a big, violent, and muscular guy, which is realistic.
Trademark Favorite Food: Not as obvious as other examples, but one of Zoey's favorite foods are grapes, which she snacks on in a lot of episodes.
Team Mom: Acts like a motherly figure to everyone, especially her little brother, Dustin.
You Go, Girl!: It's the plot of the first episode. Subverted later in the episode "Wrestling", one of the rare instances where Zoey doesn't come out on top.
Alone Among the Couples: Out of all the major characters who are still around at the end of the show, he's the only one who ends up alone (along with James, the Romantic False Lead who disappears after his break-up with Zoey).
Advertised Extra: Through he is credited as a main character for all 65 episodes, he only appears in 25 episodes and rarely contributes to the plot in a major way. This is lampshaded in one episode where he said he missed hanging out with Zoey as she spent more time with her friends.
Cannot Spit It Out: To a ridiculous extent. He spends 3 seasons pining after Zoey. In one episode, he tries to text his feelings to her, and her cell phone falls into a fountain. After Zoey finds out how he feels...he gets Put on a Bus to England.
Chick Magnet: Thanks to his dorky charm, he is not bad in this department (Melissa, Lola, Trisha Kirby, Rebecca, Gretchen, and eventually Zoey).
Funny Afro: His bushy "Jewish afro" constantly referenced by the other characters. He tends to shrug it off, but lampshades it himself after Zoey throws a pillow at him that knocks him off his chair. He gets up, pats his head and exclaims "You dented my 'fro!"
Meaningful Name: Chase (as in 'pursuit'). Came in handy for naming the series finale TV movie "Chasing Zoey" ("Chase"-ing Zoey, Chase 'n Zoey).
Nice Guy: A sweet natured, loyal, and honest person, and he gets along with everyone in the group.
Nice Jewish Boy: His bushy hair is referred to by Michael as a "crazy Jewish afro". Also, his actor is Jewish.
Odd Friendship: Chase and Logan's friendship seems to fall into this, as they are incredibly different and seem to be the kind of friendship that would not work thanks to their personalities but more than once is showed that they are close friends.
Heterosexual Life-Partners: With his best friend Chase, to the point they even have an internet show together. Also becomes this with Logan in season 4.
Jerkass Ball: Happens a few times in season 4, due to being paired with Logan more often and sometimes going along with his Jerkass antics. Particularly their shunning James because they don't want a new roommate.
Large Ham: He can be very dramatic when he wants to.
Ambiguously Bi: She definitely likes boys, but she also fawns over Zoey a lot, even more than everyone else. In "Girls will be Boys," she also says it is hot when Lola talks in her guy voice when she was disguised as a boy.
Book Smart: While it's never mentioned in the first season, the episode "Broadcast Views" reveals that she's a straight-A student and cares about getting high grades, even if she's distracted by her obsession with boys.
Brainless Beauty: Downplayed, she's flighty and shallow, but apparently a good student.
Put on a Bus to Hell: Nicole is an intensely boy-crazy, insecure kid who hates unfamiliar situations. In one episode, she had broken down sobbing when she thought she'd have to transfer to another school. In the third season premiere it's revealed that Nicole has been shipped to an all-girls boarding school.
Bunny-Ears Lawyer: Quinn is brilliant and everyone knows it, despite her many personality quirks.
Butt-Monkey: More so in the early seasons. In one episode Quinn didn't take it well when Logan and the others were making fun of her.
Clingy Jealous Girl: Most girls even interacting with Mark was an obvious Berserk Button for her. Downplayed later with Logan as it's made apparent that she didn't want him going to the prom with anyone she perceived as a threat.
Cloudcuckoolander: Big time, she has incredibly weird habits and interests (usually science experiments), to the point of being even gross at times, especially in the first season.
Ditzy Genius: She's very smart, but doesn't have much in terms of social skills.
Extraverted Nerd: A rare female example, mainly in the early seasons where she dresses like a dork, and doesn't realize how much the others find her behavior strange and awkward. In later seasons, she becomes more of a normal and pretty Hollywood Nerd who just happens to have an interest in science.
The Friend Nobody Likes: Early on the show she was barely tolerated and not even Zoey was too fond of her. It gets better in the last two seasons, when she becomes great friends with Zoey and Lola, as well as their roommate (replacing Nicole).
Gadgeteer Genius: Sometimes. More often than not, though, her inventions don't seem to work.
Meganekko: To the point where Logan actually puts her glasses back on her before their first kiss.
Opposites Attract: With Logan. She's a science-loving nerd, while Logan is a Jerk Jock. One episode reveals that Logan is good at chemistry, making them Not So Different, but this is never brought up when they become a couple.
She Cleans Up Nicely: She's more of an Extraverted Nerd in the first two seasons, but in later seasons she starts wearing fashionable outfits like her friends, even if she's still supposed to be a nerd.
What Does She See in Him?: Her crush on Mark didn't seem that strange in early seasons (as Quinn was an Extraverted NerdCloudcuckoolander and just as weird as him), but she was still dating him in season 3 and 4. At that point, Quinn was a much more normal and pretty girl who could easily do much better than him.
The Ace: Not as much as Zoey, but he's extremely athletic and good at every sport. He's also a fairly good actor and it is revealed in one episode that he is very gifted in chemistry, smart enough to tutor Zoey.
Attention Whore: He likes to take pictures of himself and autograph them to give out to girls at PCA.
Brilliant, but Lazy: He's Street Smart and good at everything except academics, and only because he thinks School Is for Losers. It's revealed that he is secretly very good at chemistry because he was forced to study the subject by his grandfather when he was a kid, so it's clear that he could be potentially good at the other subjects as well, if he just wanted to.
The Friend Nobody Likes: Big time. He's a friend due to Proximity. Being Chase and Michael's roommate, he regularly hangs out with the main group, yet Zoey and the others openly dislike him and think he's a jerk.
Chase: I know she'd never date a jerk like Logan.
Lola: He's one of your best friends!
Chase: Which is how I know he's a jerk.
Handsome Lech: Proud of his good looks and constantly flirts with many girls.
How his relationship with Quinn starts; he sees her crying and upset over her breakup with Mark and tries to comfort.
When Zoey got ruffed up by a large wrestler in a wrestling match, Logan went to defend her honor as a friend. He was sent to the same nurses office as Zoey for his troubles, but everyone appreciate the effort.
He's genuinely concerned when he thinks he accidentally broke Michael's jaw when the two were boxing.
He shows Dustin sympathy when he says a girl he asked out laughed at him.
Butt-Monkey: Often gets the role from time to time, most notably in Zoey's Balloon.
Characterization Marches On: In her early appearances, Lola could be a bit rude and snarky with her attitude, similar to Dana. From season 3 onwards, Lola becomes more friendly, funny, cheerful, and likable, getting more of a Butt-Monkey, and having more of her own personality. She also starts dressing more normal, and becoming more boy crazy.
Contrasting Replacement Character: Replaces Dana in season 2 as a new roommate for Zoey and Nicole but, aside from being both Spicy Latinas, they aren't that similar. Dana was a grumpy, sporty tomboy who doesn't get along with Nicole, Lola is a carefree, girly fashionista who gets along with everyone.
Dude Magnet: A lot of male characters bring up how "hot" and "beautiful" she is, including Michael (in the episode "Lola Likes Chase") and Logan. Also, according to Dustin, all the guys in his year have a crush on Lola and think she is hot.
Flanderization: Lola is introduced in season 2 as an independent, trendy girl with an unique style and personality, as well as an original different hairstyle (and sometimes, different hair color) in every episode. By season 3 her unique style is gone, she's fashionable in a more conventional way, and also has stereotypical personality traits of a boy-crazy shallow girl (more or less replacing Nicole, after the latter is Put on a Bus).
Genki Girl: Not to the same extent as Nicole, but she's still pretty energetic.
Goth: Subverted. Zoey and Nicole thought she was, but she was only acting that way as an acting exercise to see if she could pretend to be someone completely different from herself and have people believe it.
Multicolored Hair: In season 2, she likes to dye her hair different colours in nearly every episode, usually brown with colored streaks. Averted in season 3 and 4, where she always keeps her hair brown.
Alone Among the Couples: Out of all the major characters who are still around at the end of the show, he's the only one who ends up alone (along with Dustin, the Tagalong Kid). He doesn't even appear in the second half of the finale.
Chick Magnet: In his first appearance he manages to attract all the female students at PCA, including Zoey, Lola, and Quinn.
The Generic Guy: Other than being a nice pretty boy, he's not that interesting, especially compared to Chase.
I Want My Beloved to Be Happy: He truly loves Zoey and proved it the series finale. Not only did he give her a gold necklace confessing his love for her, but he let her keep it after they broke up. He even gave her one final kiss before he left her dorm.
All of the Other Reindeer: She has no friends, and is usually mistreated or ignored by everyone for no reason. Even Mark, who is even weirder than she is, manages to get along with some people. Stacey doesn't.
Butt-Monkey: To the extreme: her parents change phone numbers without telling her.
Extraverted Nerd: Like Quinn, a rare female example. A freaky, dorky girl who is clueless about her awkwardness.
Fake Guest Star: She appears in the majority of season 3 and 4 yet is always credited as a guest star.
Out-of-Character Moment: Slightly. Despite her unpopularity, in season 3's episode Quarantine she's seen dating a cute boy who was apparently interested in her. The boy was played by Austin Butler who in Season 4 plays James, considered the hottest guy in the school. Of course, she still has her usual bad luck, so she ends up running away and dumping him just because of a coincidence.
Dumb Jock: Like any scumbag athlete, he resorted to cheating by taking pictures of an upcoming test on his phone but unlike any clever cheater, he forgot to remove the evidence from his phone. When being told on in front on the class by Chase, who lampshaded how Vince is an example of the trope.
Easily Forgiven: By Lola at least. She tried to ignore him for a few seconds but then ends up forgiving him (and kissing him) almost immediately.
Berserk Button: He gets upset when you don't call him by his nickname.
Straw Misogynist: He and his nerdy friends have this attitude, according to them girls are useless when it comes to science and they look down at Quinn and Zoey for being girls. However, they are proven wrong when Quinn destroys their robot with her tiny one.
Adults Are Useless: As a dorm advisor, she's terrible at her job. She once stole pies the girls were selling to raise money, she spends half of her time eating or crying over something and once cancelled a planned school trip with the students so that she could drive all the way to confront her boyfriend. In one episode, she's even fired and Zoey tries to get her rehired. Literally no one wanted her back, not even Zoey's friends. The only reason she was rehired is because her replacement was a kleptomaniac.
Big Eater: When it comes to ravioli. To the point where she would not stop eating ravioli not even if she is being chased by bees.
Butt-Monkey: Especially in the episode where she is chased by bees. She also seems to have love problems and a troubled life. Played for Laughs.
