Cats Hate Water: Lucy became hydrophobic after Mike almost drowned when they were younger. Oh, and she also almost drowned trying to save him, since she didn't know how to swim; Paulo had to rescue the both of them. That most likely contributed to the phobia...
Loners Are Freaks: She was forced to play alone in pre-school. Because she didn't want dolls, but cars, and was a girl. Girls decided she was too boyish. Boys were afraid of her.
Tsundere: "Why would I be best friends with such a jerkface?"
Slap-Slap-Kiss is her style. Interestingly, as she continues to grow up, she moves closer to becoming a Kiss-Kiss-Slap tsundere.
Our male protagonist. A star athlete and regular “nice guy”, Mike often finds that the girls who vie for his attention are the source of most of his problems.
Adaptation Dye Job: Began in the author's sketches as a yellow cat, before becoming grey.
Berserker Tears: Follow the sequence and notice that, while Lucy was hurt worse, he cried more.
Beware the Nice Ones: Mike can be a nice guy, but when something pushes him to a point, like Lucy's abuse over the years and his friends taking her side during "Unrequited", he can lash out at times.
He's been overreacting lately and Lucy is all-but broken at this point.
Butt Monkey: Originally a lot. Not so much recently.
Can't Hold His Liquor: It takes very little alcohol to make Mike hilariously drunk. Which ends up directly leading to Alejandro attempting to mug the group in Confrontation. Oh God...
Super Senses: Michael has excellent hearing, to the point that sudden yelling and pep rallies really mess him up. Ace hearing indeed. The trap in Confrontation took advantage of this to get the group in an alley for mugging.
Took a Level in Jerkass: Lucy is considerably nicer to him and others than she used to be. He's, on the other hand, become less friendly to her since her Love Confession.
Daisy "Daze"
Smart and hardworking, this bubbly cheerleader spends her time immersed in books. She longs to be more than everybody’s “little sister”.
Gave Up Too Soon: Inverted with her crush on Mike. She waited so long for him that she didn't even notice Abbey liked her.
Generic Cuteness: While still seen as pretty (Augustus has called her 'gorgeous' and Carter at one point even mistook her for Lucy) Daisy is regarded as being much less attractive and slightly fatter than most of the other Main girls. However Daisy is part Ragamuffin, which develop later than most cat breeds, so her lack of attention probably stems from her poor self-confidence and the fact she isn't as developed as the other females.
Love Triangle: AbbeyxDaisyxAugustus. In canon, Abbey got her. In a What If? chapter, Augustus did.
Nice Girl Daisy despite being very occasionally immature or jealous, is very kind-hearted and supportive of her friends, often going to huge lengths to help them out.
Paulo
Paulo spends more time hitting on girls than paying attention to class. Despite his talent for timewasting, he is fiercely loyal and will always stand up for his friends.
Beta Couple: He and Jasmine were at first considered this, but then Pillow Talk subverted this.
In the chapter "Return", it's revealed that Paulo now thinks of Daisy as more of a sister anyway, and doesn't mind her going out with another guy.
However, it is hinted at in "Back and Forth" that he still doesn't want to be seen as a sexual deviant in her eyes, as he immediately notices her and seems worried about her opinion of him when Tess and Lucy start some drama because of his sleeping around and being a man-whore in general.
Catch Phrase: Paulo's abuse of the word "AWESOME" and common usage of kid, wimp, wuss, etc. when referring to Mike.
Chivalrous Pervert: When the well-being of Daisy or Lucy is in danger, Paulo tends to forget his perversion in favor of helping them or, at least, trying to. He also reacted this way when Sue got hurt in Confrontation.
Also, he absolutely refuses to make use of Lucy's fragile state when she almost imposes herself on him.
Chipper and dimwitted David sees the world a little differently to those around him. His distance from the others sometimes yields surprisingly astute observations.
Ambiguously Bi: David adores Abbey according to the chart. And this◊ or this makes it seem that David likes touching Abbey while having fun.
Now according to the new chart, he also adores Augustus.
According to a banner ad (Sue scrolling through dating site profiles of the other characters), he's labelled as Bi in the sexuality spot.
Flat Character: Although he actually tries to be this, as he attempts to protect himself, and sometimes Paulo, from drama and Character Development. His attempts to stay flat and keep the status quo is only hinted at in one or two occasions, but those two occasions actually cause the caracter development he tried to avoid.
Toxic Friend Influence: David admonishes Paulo for his positve character development, since David looked to to Paulo when he was more womanizing.
Abraham "Abbey"
Bound by a strong moral code, Abbey struggles to balance his protective nature with his short temper. While he may butt heads with the more easygoing members of the class, he’s working on it.
Shadow Archetype: His "Disaster Dominoes" version. Abbey hates abuse, that Abbey was abusive. Abbey loves Daisy, that Abbey constantly tried to beat what he didn't like out of her. Abbey gets therapy, that one clearly didn't.
Put on a Bus: During freshman year. She later got a supporting cast role in sophomore year.
Sandy
Mike’s very own green light on the horizon, Sandy is Mike’s earliest childhood friend and his current love interest. Having found success as a young model, she struggles with the demands of work, school and a budding long-distance relationship.
Jessica is a proud, quick-witted member of the cheerleading team who is never afraid to voice her opinion. Together with her closest friend Rachel, she has been quick to offer compassion to Daisy.
Berserk Button: Jessica hates it when called out about how she bullies Tess, which led to Lucy's button being pressed... Tess pretty much just takes the bullying.
Break the Cutie: Jessica got this from a lot of the school and Tess as a freshman.
Characterization Marches On: Jessica and Rachel were initially your typical high school bullies with little reason for singling out Tess aside from her being an easy target. As time went on, though, hints were gradually dropped that there was a deeper reason as to why they bullied Tess specifically, a reason that was fully revealed in "Pillow Talk".
A true flirt, Rachel revels in playful jokes that make light of those around her. While her open nature is often confronting to friends, her cheerful demeanour always shines through.

Jasmine "Jazz" "Jazzie"
A peppy freshman girl whose life is dominated by school activities. While she’d ordinarily keep to her own group of friends, Jasmine has taken an immediate liking to Paulo, happily adopting the role of his girlfriend and principal partner-in-crime.
Beta Couple: She and Paulo were considered this at first, but "Pillow Talk" later subverted this. ** And yet it's been unsubverted at the end of "Carry Me".
Calm and composed, Augustus is always sure of himself and executes his tasks with quiet efficiency and biting wit. While he keeps his emotions close to his vest, there’s one girl who can unravel everything…
Attempted Rape: Final Fantasy Cat looked like he was about to do this to Daisy, but Abbey intervened, though it turns out he wouldn't have gone through with it.
Lucy’s first pet, and the loudest by far. Yashy is something of a prodigy, with a sharp wit that betrays her young age. Bratty, loudmouthed and rude, deep down she wants nothing more for Mom to settle down with her flea.
Bratty Half-Pint: What she lacks in size, she more than makes up for in volume.
Innocent and naive, Chirpy remains in awe of the world around her. She clings to Yashy and always does her best to follow the examples of grown-ups (while making frequent mistakes in the process.)
Lucy’s most mature pet, Lily is a source of wisdom for much of the cast (and babysitter to others.) Patient and understanding, she is usually able to steer her friends in the right direction.
Mike’s pet bird Blur was rescued from a fire as a youngster and has trouble remembering what came before the incident. He counts Yashy as a close friend and can often be seen playing or arguing with her.
A rich party girl with a rebellious streak, Tess departed the scorched earth of Junior year to find newer, younger friends. She has since struggled to reconcile her upcoming graduation with the close friendships she quickly forged.
Butt Monkey: Tess has minor butt monkey time around Jessica and Rachel.
Hard Drinking Party Girl: Tess has drinking mentioned in her character bio. She was seen drinking wine in the "Arrival" chapter of the Summer Vacation arc.
Alec “McCain” McCain remains detached at all times, making blunt pronouncements in situations which do not always welcome them. His tone-deaf flavour of cold rationality doesn’t earn him many favours with most of the cast.
Mild-mannered popcorn merchant Amaya is Sue's best friend. She chooses to remain mute. Her job at the cinema can sometimes be very useful to those who know her!
Cute Mute: Gives off this impression due to her insanely shy nature. She's actually The Silent Bob.
Katherine "Katie" He-
Precocious Katie spends most of her time worrying about makeup and hair styles and has been duly rewarded by her position as the most popular girl in school. She’s not necessarily mean and cruel… she just doesn’t think too much about others.
Katie’s best friend. Fluent in the written word, Stacy’s peers haven’t (yet) deterred her from a passion for reportage, creative writing and poetry.
Flower Girl
This mysterious girl is absent from just about everything besides David’s fantasies. While she remains unaware, she has completely captured David’s affections, and he spends a lot of his time clumsily stalking her.
Molly
Abbey’s little sister seems to have an endless reserve of childish positivity, showing strong dedication to schoolwork and her local Girl Scout troop. She loves her brother dearly, and shoulders more of their shared burden than he’d like.
A hapless kid dragged into various misadventures by other members of the cast, Justin is generally seen looking for cover and wishing he could just go back home.
Some keen-eyed forum users suggest he was the one who date-raped Tess when she was a freshman.
Combat Sadomasochist: Alejandro took two of Lucy's kicks, had his teeth smashed into each other hard enough to chip one and draw blood, and was still okay enough to beat Lucy senseless before Mike came back, smashing his face into an alley floor and still not stopping him. It took Mike and Lucy together to turn the fight around (at which point it became a No-Holds-Barred Beatdown). And he beat Mike (and was about to crush his skull) before all this happened.
Sue: So um... why are you picking on us? We're like... thirteen, ya know. If you think we're loaded with cash, then you're kind of an idiot. Alejandro: *fingers Sue's chin* So then what's the harm in givin' us all yer money? Sue: *slaps Alejandro's hand away* Because we actually NEED it! Alejandro: *punches Sue in the face* WHO THE HELL CARES ABOUT YOU?!?
Would Hit a Girl: And hits two on-panel. It's implied that he hit his old girlfriend.
