    Corey Jaron Riffin
"Lemme solo here for a sec."
Voiced by: Lyon Smith

The series protagonist, lead guitarist/singer of Grojband, and Trina Riffin's younger brother. Charismatic, laidback, and always determined to make the best music he and his band can, 13-year-old Corey Riffin uses Trina's diary entries as inspiration for lyrics to his band's work.

  • The Ace: He's an all-around skilled musician with a confident and charismatic personality. The only thing he isn't good at is coming up with lyrics for his work, but when he has Trina's diary on hand, he can come up with words on the fly.
  • Affectionate Nickname: Laney calls him "Core".
  • Ambiguously Bi: He has plenty of Ship Tease with Laney and they hook up in "Hear Us Rock!", but he's also closer to Nick Mallory than most heterosexual males would be: he's perfectly happy to hang off his neck, hug him in front of an audience, and is generally quite touchy-feely with him.
  • Annoying Younger Sibling: To Trina, as both Corey and her are in a sibling rivalry of which he is on top of.
  • Attention Deficit... Ooh, Shiny!: According to Word of God, Corey has both OCD and ADD. This means he'll decide on a genre or venue for the band to pursue, and once they get it, gives it up to pursue something else.
  • Awesome Mc Coolname: Corey Jaron Riffin, this is supported in the episode "Dueling Buttons", when he inputs the intials "CJR" in the game.
  • Aw, Look! They Really Do Love Each Other: Admits he feels bad for putting Trina into a nightmare-induced coma in "Dreamreaver", and feels even more so after seeing her nice side that loves him inside her brain.
  • Badass Adorable: Don't let his precocious age fool you, Corey can be pretty badass when he has to be.
  • Berserk Button: Elevator music is one of the things that really angers him, next to having his dream taken away.
  • Beware the Nice Ones: He's pretty scary when he's angry, even in the episode "Dueling Buttons" in which he almost goes into Diary Mode.
  • Bilingual Bonus: His middle name Jaron, comes from the Hebrew word Yaron.
  • Book Dumb: He's not much of a songwriter without Trina's diary, but his musical talent, penchant for crazy schemes that somehow work, and his end-of-episode insights show he's definitely no idiot.
  • Brilliant, but Lazy: Lampshaded constantly. He claims to need Trina's diary to write lyrics, yet his "final thoughts" show that he's perfectly capable of Waxing Lyrical himself, yet he doesn't seem to be aware of it.
  • Bunny-Ears Lawyer: His "crazy plans that just might work" usually work.
  • Cain and Abel: To say he and Trina do not get along is an understatement.
  • Catch Phrase: Corey ends each episode with "Thanks for coming out, everyone!" and closing a garage door. He'll also sometimes talk of "a crazy plan that just might work". He even says "We have Liftoff!" on some of the episodes where Trina writes her diary in anger mode.
  • Character Development: While he's initially Oblivious to Love, he slowly shows signs of affection towards Laney as the series progresses, in fact, in the second half of Season One, he starts to treat her like a lady and stops calling her a dude. And in the final episode, he and Laney finally get together.
  • Chick Magnet: As a result of being a popular musician, he's got lots of fangirls.
  • Company Cross References: The stylized skull on his hat is the same one on Duncan's shirt.
  • Cry Cute: He rarely gets emotional but when he does his innocence shows.
  • Curtains Match the Window: When his irises are shown.
  • Determinator: He will let nothing stand in the way of making his next big musical hit.
  • Distressed Dude: So far he has been controlled by a helmet (albeit briefly, as he takes it off by fighting it), a plant, and an evil guitar; all due to his trusting nature. He even got kidnapped (along with the rest of the band) by two little girls!
  • Dreadful Musician: While he's fantastic at playing the guitar and singing, he's terrible at is coming up with good lyrics, but only without Trina's diary.
  • Easily Forgiven: By Nick Mallory, despite the various things Corey has done to him like pushing him off of a plank, forcing him to go on a date with a monster, and using him as Trina bait.
  • Even the Guys Want Him: He's had more than his share of fanboys in his musical career.
  • Expressive Accessory: The puffball on his beanie droops when he gets sad or startled.
  • Four-Temperament Ensemble: He has a very cheerful personality, which would make him the sanguine one.
  • Friend to All Living Things: To a slightly lesser extent than Nick Mallory, as he is often shown having animals cuddle up to him, usually in his Final Thought. This also leads him to be gullible and hence is very susceptible to mind control.
  • Genius Ditz: He's able to come up with some very clever plans to get Trina into Diary Mode, is a very good musician and singer, can be genuinely insightful at times, and is very good at creating lyrics on the wing when he has Trina's diary at hand. On the other hand, he's also prone to saying nonsense he treats as wisdom, is Oblivious to Love, sometimes doesn't think his plans through, and generally has trouble coming up with lyrics without Trina's diary as inspiration.
  • Guile Hero: The fact that he cunningly manipulates Trina into going into Diary Mode, on a near episodic basis, definitely makes him qualify.
  • Happily Adopted: By his dad, as revealed by Word of God.
  • He Cleans Up Nicely: He dresses up for the wedding gig. It's also the first time the viewers don't see him wearing a hat.
  • The Hero: The protagonist of the show and leader of Grojband.
  • Hidden Depths: The monologue in "Girl Fest" reveals he has some repressed rage issues. Confirmed in "Dueling Buttons" when losing to Trina at a video game drives him over the edge.
  • Hiss Before Fleeing: Did this when Trina frightened him when they were younger.
  • I Can't Dance: Revealed in "Bee Bop a Loofah", when Corey dances up a sweat.
    Laney (to Corey): Congrats, you dance like a mom.
  • Improbable Aiming Skills: With a guitar pick. In fact, in the online videos on the Canadian website, it slices through a bouquet of flowers Mayor Mellow was holding for a girl, a water bottle, and his winning dog's fur.
  • Invisible Parents: His adopted father is never seen or mentioned in the series.
  • Keet: He has his moments of such.
  • The Leader: Of Grojband obviously.
  • Manipulative Bastard: Like his biological sister, he shows a streak of this at times.
  • Meaningful Name: His middle name, Jaron, comes from the hebrew word meaning Yaron, which means to sing or shout phrases, which makes sense because he's often seen singing and/or shouting.
    • Also doubling as a Shout-Out is his first name, which was after Corey Crewe, a Canadian musician who formed a duo with Trina Crewe, the namesake of his sister.
  • Missing Mom: According to Word of God, he and Trina were adopted by a single father and there was no mother.
  • Nice Hat: He wears his beanie everywhere, even to bed, in which he wears a blue version of when he sleeps.
  • No Sense of Personal Space: Mostly towards Laney, although she doesn't mind having Corey in such close contact to him.
  • Oblivious to Love: To Laney at first, then in later episodes, it's heavily implied that he is in fact aware of her feelings for him (He thought Laney was cute in her pageant outfit; during the song in "For Hat and Country", he calls Laney "my gal"; and it is hinted that he returns her feelings after they kiss in "Metrognome"). Ultimately, They Do in the final episode.
  • OOC Is Serious Business: While he's calm most of the time, there are rare instances when he loses his cool.
    • He lost it in "Love in a Nethervator", due to elevator music being his Berserk Button.
    • He has an even bigger one in "Dueling Buttons", where he completely snaps when Trina steals his dream and his fame.
    Laney (slowly): Breathe.
    Corey: I've been breathing all my life, and it's got me nothing!
  • Pink Girl, Blue Boy: The Blue Boy to Trina's Pink Girl (in terms of hair color).
  • Plot Allergy:
    • It's shown that he's allergic to cats, specifically cat dander, as shown in "Super Zeroes" as he had no problems holding Mina's danderless cat.
    • Wheelie, the cat in a roller skate, is also presumed to be danderless, as Corey hugs him and he didn't sneeze.
    • His allergic reaction to cat dander has snapped him out of his brainwashing in the episode "One Plant Band".
  • The Pollyanna: He's almost never in a bad mood.
  • Red Oni, Blue Oni: The red oni to Laney's blue, oddly since it's in stark contrast to their hair colors.
  • Signing-Off Catchphrase: "Thanks for coming out, everyone!"
  • Super OCD: His OCD rituals are known to have him book a gig at any place at every chance he gets, not letting even one slip by.
  • Trademark Favorite Drink: His favorite drink is chocolate milk.
  • Trademark Favorite Food: Blueberries, or anything that has blueberries in it, like blueberry waffles.
  • Will They or Won't They?: With Laney, whom he shares a ton of Ship Tease with.
    • They Do: Corey officaly hooks up with Laney in "Hear Us Rock!"
  • You Gotta Have Blue Hair: He has blue hair to match with his blue eyes.

    Laney Penn
"When you're in love, even doing nothing at all is wonderful."
Voiced by: Bryn McAuley

The bassist, self-proclaimed band manager, and only female member of Grojband (although she's often mistaken to be a boy). Laney is a fearless tomboy and probably the most versatile member of the group, with a snarky attitude and a fiery temper. She has a huge crush on Corey.

  • Affectionate Nickname: Corey calls her "Lanes".
  • Badass Adorable: Pretty dang cute and pretty dang tough to boot.
  • Beautiful All Along: In "Queen Bee".
  • Berserk Button: Don't be dissing the band aloud around her, as Trina learned in the episode "Queen Bee".
    Sorry Core, she dissed the band! Nobody disses the band.
    • Also having everyone think that she's a boy, although she can never seem to correct them.
  • Blonde, Brunette, Redhead: The redhead to Kate's blonde and Allie's brunette.
  • Boyish Short Hair: She wears her hair quite short, which might explain why she's often mistaken for a dude.
  • Burning with Anger: The hair on her head often literally combusts when she gets angry.
  • Catch Phrase: Something alone the lines of "Where will we get lyrics?"
  • The Chick / The Lancer: As the sole female of Grojband and the closest of the bunch towards Corey, she fulfills both roles.
  • Creepy Monotone: Usually does this when she's being sarcastic.
  • Deadpan Snarker: Prone to pout sarcasm, usually in response to one of Corey's plans or Kin and Kon being silly.
  • Expy: According to the creators, she's based on Watts from the movie Some Kind of Wonderful.
  • Fiery Redhead: Bonus points for catching fire every so often. See Burning with Anger above.
  • Foil: Her crush on Corey is a contrast to Trina's obsession with Nick Mallory; While Trina worships the ground Nick walks on and thinks he can do no wrong, Laney doesn't let her feelings for Corey stop her from voicing her own opinions, and she often gets angry at him.
  • Four-Temperament Ensemble: Her cool head and sarcastic tendencies make her the phlegmatic one of Grojband.
  • Friend to All Living Things: Exaggerated. She takes a liking to all animals, including Blade Stabbington's pet rat, a bee, and a sheepdog dressed as a unicorn.
  • Hair Flip: Does one while speaking in a Trina impersonation.
  • Hell-Bent for Leather: She wears folded over leather boots.
  • Hypocrite:
    • She's shown to dislike "Boy-Crazy Girly Girls" but she herself has a MAJOR crush on Corey and is heavily implied to be a closet Girly Girl.
    • Also she gets mad that Singer Candy Jams doesn't have the creative mind to write her own songs when....well you know.
  • I Don't Want to Ruin Our Friendship: She's crazy in love with Corey, but Kin and Kon's constant butting-in disrupts their little dates that she decides to stay as friends for now so that the others don't feel left out. In fact, this almost caused Grojband to get disbanded in the episode "All You Need is Cake".
  • Intimate Artistry: A G-rated version. One of the ways she and Corey spend time together is by playing in Grojband, which is partially why she organized it in the first place.
  • Invisible Parents: Her parents are never seen or mentioned.
  • Kick the Dog: Quite a literal example in "Dreamreaver" where she kicks a poodle version of Mina.
  • Lady Looks Like a Dude: To the band at least. Later on this averted as Corey starts calling her a lady in episodes like "Pop Goes the Bubble" and "Girl Fest".
  • The Lancer: She’s pretty much second-in-command being the (self declared) band manager, constantly playing Only Sane Woman and the one who snarks at Corey's harebrained schemes.
  • Meaningful Name / Shout-Out: Switch the "Lane" and "Penn" parts of her name, and you get the title to a very famous song.note 
  • Morning Routine: Appears to have one according to one of the online videos from the Canadian website.
  • Nobody Loves the Bassist: A little. She certainly puts up with a lot of flack from her bandmates and is often disregarded or ignored.
  • Ocular Gushers: In the episode "One-Plant Band" after Corey angrily yelled at her for being right all the time.
  • One of the Boys: To the point where she's frequently mistaken for an actual boy, much to her annoyance.
  • Only Child Syndrome: She is the only band member to not have a sibling.
  • Only Sane Woman: She has the most common sense and maturity out of all of the band, which she reflects on this in "It's In The Card" when the band breaks up.
  • Quirky Curls: As seen in one of the online shorts, although fans aren't sure if it's natural or just bed head hair.
  • Redhead In Green: She has short red hair and a striped green t-shirt.
  • Running Gag: Having her gender mistaken.
    • In "Dance of the Dead", everyone keeps mistaking her everyday outfit for a scary costume.
  • She Cleans Up Nicely: While competing in a beauty pageant, she wore a black and green dress and her hair was in an elegant updo. Even Corey was amazed by how beautiful she looked.
  • Shorter Means Smarter: Hence why she's the (largely self-declared) band manager.
  • Single-Target Sexuality: Only has eyes for Corey, not even showing attraction to Nick Mallory.
  • The Smurfette Principle: She's the only female member of the band, yet mistaken to be a boy.
  • Stronger Than They Look: Despite being the shortest member of the band, Laney is very strong for her size. In "Pop Goes the Bubble", she easily lifts up Trina and boredly holds her above a manhole.
  • Team Mom: She frequently holds the band back from their more silly acts. This is reflected in "It's In The Card" during her recorded message when she comments she can often be "grumble grumble" and a "mother hen".
  • Teens Are Short: She's the second shortest of the band, yet her tall ambition makes up for it.
  • They Do: She and Corey officially hook up in "Hear Us Rock!"
  • Tomboy with a Girly Streak: It's heavily implied she's a closet Girly Girl. She claims to not like girly things but a few shots we get of her room and the official concept art of her bedroom says otherwise. She's also shown fondness for unicorns and cute animals.
    "We played for royalty, I got a kiss from a unicorn. Not a bad gig."
  • Trademark Favorite Food: Ketchup-flavored Potato Chips.
  • Will They or Won't They?: With Corey, whom she shares a ton of Ship Tease with.
  • Women Are Wiser: The sole girl of Grojband and the one with the most common sense and the most maturity.
  • Zettai Ryouiki: She doesn't normally wear one, but she puts some on with her pageant dress and her Livewire costume.

    Kin Kujira
Voiced by: Sergio Di Zio

Kon's twin brother, keyboardist for Grojband, and all-around loony genius. Kin is in charge of the band's pyrotechnics, lighting, computers, and any other technology or gadgetry that could come in handy when trying to make Trina go into Diary Mode.

    Kon Kujira
Voiced by: Tim Beresford

Kin's twin brother and drummer for Grojband. Unlike his diminutive and sometimes crazy genius of a brother, Kon is a big, dopey, fun-loving goofball with an appetite as big as his heart. He seems to have a unrequited crush on Trina Riffin, who loathes him even more than Corey.

  • All Drummers Are Animals: Sometimes acts the part. It got literal in "Hair Today, Kon Tomorrow" when he got turned into a dog.
  • Alliterative Name: Kon Kujira.
  • Alleged Lookalikes: He and Kin claim to be identical twins, despite looking nothing like each other.
  • Animorphism: In "Hair Today, Kon Tomorrow", Kon turns into a dog for the majority of the episode - sort of. 'Kon Dog' is actually regular Kon after having spilled hair tonic on himself, getting zapped by a magic wand, and hitting his head. This results in him growing fur along with amnesia that causes him to believe that he's a dog.
  • Asian Airhead: Kon is a rare male example, and a rarer Asian Genius Ditz.
  • Big Eater: He's almost always hungry and loves eating.
  • Big Fun: The chubbiest member of the band but also the most excitable and fun-loving.
  • The Big Guy: In contrast to his brother Kin, who is instead The Smart Guy, Kon is the Big Fun Dumb Muscle who the band turn to for brute force.
  • Book Dumb: When it comes to math, which is part of the reason why he failed six years worth of it as shown in the episode "Math of Kon".
  • Brains and Brawn: The brawn to Kin's brains.
  • Conjoined Twins: He and Kin were born as this, and have the scars to prove it. It's also worth noting that Kon has Kin's nipples on his back, which is lampshaded by Corey in "In-D Road Rager".
  • Dumb and Drummer: Kon obviously isn't the smartest member of the band.
  • Dumb Muscle: The strongest and least intelligent member of Grojband.
  • Expy: It’s very hard to look at him and not think of Owen.
  • Fat and Skinny: The fat to Kin's skinny.
  • Fat Comic Relief: The heaviest of the band and also the most comical member.
  • Fat Idiot: He's not the brightest bulb in the box, but he often crosses over into Genius Ditz.
  • Four-Temperament Ensemble: His passionate and fun-loving personality makes him the choleric one of the bunch.
  • Gasshole: Often pulls off some very powerful belches.
  • Genius Ditz: Although generally airheaded, Kon is every bit as knowledgeable in Rock Lore as his twin and has been show to be able to understand things like math if they're delivered to him in a form he can get around, such as drumming.
  • Gentle Giant: Kon is very nice and a lot bigger than his bandmates.
  • Invisible Parents: He and Kin mention their parents in two episodes, but otherwise, they never appear.
  • "It" Is Dehumanizing: Trina refers to Kon as an "it" on several occasions, making it quite evident that his feelings for her 100% one-sided.
  • No-Neck Chump: Apparently, he has no neck.
  • Obfuscating Stupidity: According to Word of God anyway, although it is hinted at a few times in the series, given his Genius Ditz and Book Dumb tendencies.
  • Polar Opposite Twins: With Kin, who is smaller, smarter, and generally less sane than him.
  • Precocious Crush: To Trina, who has nothing but contempt for him (moreso than the other members of Grojband).
  • Shout-Out: He and Kin's names put together make King Kong, while their last names reference another famous giant movie monster: Godzilla (aka Gojira).
  • Sibling Team: With Kin.
  • Smarter Than You Look: He becomes a math genius when he's drumming, when not, he doesn't know how many hands make up six fingers. Likewise, Depending on the Writer, he has his moments in which he's shown to be intelligant, and that his dim-witted persona is an act.
  • The Storyteller: He and Kin tell tales of Rock Lore.
  • Trademark Favorite Food: Cheese.



    Katrina "Trina" Riffin
"Just try to imagine...just little I care, and junk."
Voiced by: Alyson Court

The show's main antagonist and Corey's 16-year-old sister. Mean and vicious, Trina loathes her brother and his friends and will stop at nothing to ruin Grojband, but also has an unrequited crush on Nick Mallory. Once per Episode, she's overcome with emotion and goes into Diary Mode, where she writes in her diary and Corey uses her words as lyrical inspiration.

  • Affectionate Nickname: Corey usually calls her "Sis".
  • Alpha Bitch: Full stop. She's as selfish, bossy, vain, bad-tempered, and superficial as they come.
  • Asshole Victim: She such a nasty bitch that you really cannot feel sorry for her no matter what kind of misfortune Corey and his friends cause to her.
  • The Assimilator: She melds her brain with everyone in Peaceville using a sparklebrain in "Ahead of Our Tone".
  • Aw, Look! They Really Do Love Each Other: Has several moments with Mina that shows she really does care for her as a friend and not just as a slave.
  • Bad Boss: To Mina, whom she generally shows very little kindness towards.
  • Beauty Is Never Tarnished: Invoked in "Inn Er Face".
  • Big Bad: Especially in the episodes "Ahead of our Own Tone" and "The Bandidate". Much of the series is about her antagonizing her brother so she can ruin his band.
  • Big Sister Bully: To Corey, whom she constantly screams at and abuses. However, Corey is cunning enough that he always ends up getting the upper had over her in the end. A few episodes do imply she used to be a Cool Big Sis though.
  • Bratty Teenage Daughter: Like most of her kind, she's whines constantly about how miserable she thinks her life is (which Corey and co. then use for their songs) and obsesses herself with boys and shopping.
  • Butt-Monkey / The Chew Toy: The entire show is basically about her brother and his friends trying to drive her crazy so she can vent in her diary and they can steal it for their songs.
  • Cain and Abel: She and Corey do not get along at all, and on at least one occasion, she has actually tried to kill her brother.
  • Catch Phrase: "BAM!"
  • Childhood Friends: With Mina, as they've been friends since kindergarten.
  • Clark Kenting: Her math-loving alter ego wears glasses, drab clothing and a Prim and Proper Bun. She also acts nicer towards Mina.
  • Clingy Jealous Girl: She'll be threatened by any girl who tries to get close to Nick, even if they're just birds.
  • Closet Geek: Towards math. She hides it by taking on the alias of a nerd named Trigonometrina.
  • Color Motif: Pink. She even has an obsession of the color and gives names to pink things that contain the word "pink", she even named her pink car Pinktastic and her pink sweater Pinkcredible.
  • Comfort Food: Cupcakes.
    Tastes like sad...
  • Companion Cube: Pinkredible, her favorite sweater.
  • Cry Cute: In her sad Diary Modes in the episodes "Soulin' Down the Road" and "Hear us, Rock! - Part 1"
  • Curtains Match the Window: When her irises are shown.
    • Her favorite sweater, Pinkredible, complements her hair color.
  • Cyborg: Turns into one for a good chunk of "Ahead of Our Own Tone" because she was the first guinea pig - er "Lucky Customer" to try out the new Blab Tab In-brain Implant.
  • Death Glare: Frequently delivers these, especially in her angry Diary Modes.
  • Drama Queen: In "Six Strings of Evil" she referred to a day where Nick politely declined her offer of going out for a milkshake as the worst day of her whole life, even though worse things happen to her all the time.
  • Drives Like Crazy: Tends to suffer from road rage.
  • Elmuh Fudd Syndwome: When she was younger.
  • Emotional Powers: When writing in her diary, she causes her surroundings to go crazy as she puts massive amounts of passion into venting her emotions.
  • Evil Makeover: Once she gets the brain implant in "Ahead of Our Own Tone" her hair and clothes turn into a dark-ish purple with two streaks of pink in the middle of her hair, squared pupils with green eyes, and her voice changes to a Machine Monotone.
  • Evil Overlord: Cyborg!Trina in the Bad Future of "Ahead of Our Own Tone".
  • Evil Plan: Her plans get called this whether it's dealing with her younger biological brother's band and/or trying to make Nick fall for her.
  • Exotic Eye Designs: Sometimes, when she's thinking of romancing hunky Nick Mallory - which is often - her pupils turn pink hearts.
  • Four-Temperament Ensemble: She usually has a Choleric personality in contrast to her more laidback brother, but she puts on a Sanguine one for Nick Mallory.
  • Game Face: Displays this when writing her diary in anger mode. She also made the same face when she was just really upset (even as a kid).
  • Genki Girl: She ONLY acts like this whenever Nick Mallory is around. Otherwise, she would be faking her Genkiness. She even would fake her personality by being the Four-Temperament Ensemble's Sanguine, when her real ensemble temperament is Choleric.
  • Good with Numbers: She loves math and numbers so much, she would often hide the fact behind her alter-ego, Trigonometrina, as she'd never admit it in public.
  • Hair-Trigger Temper: She has severe anger issues.
  • Happily Adopted: By her dad, according to Word of God.
  • Hartman Hips: Her hips are noticeable wider compared to her chest.
  • Hate Sink: She's as detestable as possible by the standards of the show. She's a Big Sister Bully who torments her brother and tries to ruin his life often for no reason other than spite. She's a Bad Boss who abuses her one loyal underling Mina. Not to mention some of her schemes involve outright attempted murder all for the sake of getting back at Corey.
  • Held Back in School: For three years.
  • Hidden Depths: Secretly loves math.
  • Hidden Heart of Gold: She has one beneath all the crazy, though it was locked away her good side years ago. We even see it visibly as Katrina in "Dreamreaver".
  • High Class Gloves: Wears them as part of her pageant outfit in "Queen Bee".
  • Hive Queen: In "Ahead of our own Tone", thanks to the implant.
  • Hoist by Their Own Petard: Her refusal to assimilate Mina in "Ahead of our own Tone" leads to Mina taking an implant from Corey and making her listen to her brothers music via the Hivemind.
  • Hypocrite:
    • In "Dueling Buttons", she's shown to be singing and enjoying music, despite generally having an intense hatred of her brother's band.
    • In "Smash Up Terby", she tells Kin "No Nerding", yet in "Math of Kon", she's secretly a nerd.
  • iSophagus: In "On the Air and Out to Sea", her braces picks up radio transmissions from her brother's radio station.
  • Invisible Parents: Her adopted father is never seen or mentioned in the series.
  • Irrational Hatred: She LOATHES Grojband: their music, their members, and everything they stand for.
  • It's All About Me: She often puts her personal goals (namely ruining Corey's life and dating Nick Mallory) above everything and everyone else. As she put it in "Kon-Fusion":
    "I am going to touch Nick Mallory's hand, even if it ruins everything for everyone forever!"
    • Taken Up to Eleven in "Hear Us Rock!," where she helps the Orbs in their grudge match against Grojband, preferring to let the Earth and everyone on it (except for herself and Nick Mallory) be destroyed rather then let Corey and his band be the ones who saved it.
  • Jerkass: Absolutely. She's got a horrible temper, she constantly abuses her friend, she hates her brother and his friends to the point of wanting to destroy his dreams, and she cares about nothing except making Nick Mallory her boyfriend.
  • Jerk with a Heart of Gold: On rare occasions, usually towards Mina.
  • Jerk With A Heart Of Jerk: On the flip side, her lust for Nick Mallory brings out the worst in her and can even completely override her care for Mina.
  • Laughably Evil: She may be a god awful horrible person, but she's so over the top ridiculous in her schemes and attitude that she can be hilarious to watch.
  • Like Is, Like, a Comma: Due to her Valley Girl tendencies, she abuses the word "like" to no end.
  • Love Makes You Evil: At least one of the reasons "Katrina" became Trina is to win over Nick Mallory. This is ironic since Nick has only ever shown interest in the softer side of Trina, which means she would have been better off not changing at all.
  • Mad Libs Catchphrase: "Hashtag (Insert word here)!"
  • Machine Monotone: Speaks in this tone of voice after the implant turns her into a Cyborg in "Ahead of Our Own Tone".
  • Manipulative Bitch: Shows signs of this at times, especially in the episode "In-D Road Rager".
  • Meaningful Name / Shout-Out: She's named after the late Trina Crewe, a Canadian musician who formed a duo with Corey Crewe, who is of course her brother's namesake.
  • Missing Mom: According to Word of God, she and Corey were adopted by a single father and there was no mother.
  • More Than Mind Control: Agrees on erupting Mount Peaceville when the demon guitar starts talking to her at the end of "Six Strings of Evil".
  • The Muse: Serves as an unwitting one to Grojband, who always use her diary as inspiration for their songs. Corey's inability to come up with good lyrics is part of the reason.
  • No Indoor Voice: She tends to yell a lot when she's angry. HONESTLY.
  • Obfuscating Stupidity: Keeps her love of math hidden so she won't be associated with nerds.
  • Only Known by Their Nickname: Hates the name Katrina and insists on being called Trina. It's later shown that she openly went by Katrina when she Used to Be a Sweet Kid, and her repressed nice side still goes by it.
  • Opinion Flip Flop: When she says she hates or doesn't care about something, she will immediately claim she likes it if it turns out Nick likes it. This habit was used against her in "Hear Us Rock!".
  • Out-Gambitted: In "Wish Upon a Jug".
  • Overly Long Name: Her math-loving alter ego's full name is Trigonometric Trina Adelaide.
  • Pet the Dog: Towards Mina as Trigonometrina in "Math of Kon" as the two spend a nice day together.
    • Also at the end of "Queen Bee", with her giving her crown over to a joyful Mina. Really, all of her actual friendship moments with Mina qualify.
    • Her love and protectiveness toward Mr. Mooseface.
    • There's also a literal example in "Hair Today"... which doesn't last once she learns the dog is actually Kon under a spell.
  • Pink Girl, Blue Boy: The Pink Girl to Corey's Blue Boy (In terms of hair color).
  • Pink Means Feminine / Princesses Prefer Pink: She's a princess in her own mind, but often wears pink and is obsessed with pink-coloured things like her car and her sweater.
  • Plot Allergy: In "Kon-Fusion", it's revealed she's allergic to bread crusts, and in "Pop Goes the Bubble", she's also allergic to bubbles.
  • Prim and Proper Bun: She sports her hair in one in the episodes "Math of Kon" (as Trigonometrina), and "Rockersize".
  • Punny Name: Her nerd alias of Trigonometrina.
  • Rage Breaking Point: Writes her diary in Anger Mode whenever she reaches this.
  • Reality Warper:
    • A mild case. Whenever she writes lyrics-worthy entries in her diary, her emotions manifest around her, and strange phenomenon happens depending on the emotion.
    • She can defy natural human bodily functions, she as resisted the urge to drool or sweat, because she considers it to be "for losers". Laney actually questions if Trina is actually a robot.
  • Red Eyes, Take Warning: When writing her diary in anger mode or in fear mode.
  • Saying Sound Effects Out Loud: Prone to this.
    • "Sigh, Mina."
    • "SWOON!"
    • "Scoff!"
    • "Mega gasp!"
  • Secret Diary: Uses one, although it's not that secret since that's where Grojband gets their lyrics from.
  • Secret Identity: Her nerd alias, Trigonometrina.
  • Security Blanket: Mr. Mooseface, her favorite stuffed toy she loved during childhood, she's still very protective of it.
  • Sore Loser: She did not take her defeat in the episode "Queen Bee" very well.
  • Stalker with a Crush: Towards Nick.
  • The Stool Pigeon: Rats the band out to Mayor Mellow whenever she wants them out of the way and they're doing something he doesn't agree with.
  • Stupid Evil / Revenge Before Reason: She's willing to die (or at least get badly hurt) from falling if it ruins her brother's band's reputation in "Super Zeroes", all because they showed her up at Mick Mallory's birthday.
  • Sweet Tooth: She loves chocolate.
  • Throw the Dog a Bone: Whenever she happily goes diary or whenever Nick Mallory is nice to her.
  • Teens Are Monsters: While she's not the only teenager in the show, she's certainly the most monstrous.
  • Token Evil Teammate: Is an unwitting help to the band as much as she is a hindrance.
  • Too Dumb to Live: In "Dance of the Dead", she is so blinded by love for Nick Mallory, that she is unable to notice said boy has currently been zombified and is hungry for brains. When Zombie Nick notices Mina dressed as a giant brain and tries to go for her instead, Trina knocks Mina out of the way and instead insists Nick bite her head, even going so far as to stick her head into Nick's mouth. She gets zombified for her troubles.
  • Too Important to Walk: Has Mina carry her on piggyback when she doesn't feel like walking.
  • Took a Level in Jerkass: If you can believe it. In the pilot, Trina was merely overbearing and a tad dramatic - flash forward to the latter half of the season where Trina openly admits to trying to kill Corey, going so far as to call Mina a groupie and not even a BFF and leaving the entire world to die so she could be with Nick Mallory forever. One can only hope Mina finally snapping and calling her out on her bullshit had positive after effects.
  • Tsundere: Normally abuses Mina, but treats her nicely when disguised as Trigonometrina. Shows some signs of it toward her brother sometimes too.
  • Twitchy Eye: Frequently develops these due to her emotional issues.
  • Used to Be a Sweet Kid: Several flashbacks imply she was this. When Grojband goes on a Journey to the Center of the Mind, they also encounter her nicer Katrina personality, who is locked away inside of her.
  • Why Did It Have to Be Snakes?: In the episode "No Strings Attached", she was traumatized after a scary encounter with puppets when she was a kid. Taken a bit further considering that the "Pretty Puppet" she picked up turned out to be scary.
  • Valley Girl: Usually speaks like one.
  • Verbal Tic: She sometimes ends her sentences with "and junk."
  • Yank the Dog's Chain: Trina does this to Mina after she regains her personality near the end of "Knights to Remember" as she chases her down.
  • You Gotta Have Blue Hair: Pink in this case.
  • Zettai Ryouiki: She wears a Grade A by default, and a Grade C in "The Pirate Lounge for Me".

    Bernadette "Mina" Beff
"Already here!"
Voiced by: Denise Oliver

Trina's 14-year-old best friend (for a given definition of the term) and polar opposite in terms of personality. A frequent victim of Trina's abuse, Mina carries out all of the unpleasant parts of Trina's anti-Corey and Nick Mallory-attracting plans but nonetheless remains loyal to her.

  • Affectionate Nickname: Trina has a lot of cutesy nicknames for Mina, although considering their relationship, "affectionate" might be a strong word.
  • Alliterative Name: Her birth name was Bernadette Beff, but Trina made her have it legally changed to Mina so that as best friends, their names would rhyme.
  • Ambiguously Bi: She's shown to be as obsessed about Nick Mallory as all the other girls on the show are, but her relationship with Trina is rife with Les Yay undertones.
  • Aw, Look! They Really Do Love Each Other: Despite the abuse Trina puts on her, Mina still sincerely loves her as a friend.
  • Badass Biker: In "Soulin' Down the Road", where she gets to drive a Cool Bike.
  • Backstabbing the Alpha Bitch: Delivers one to Trina in the finale, where she unleashes a verbal tirade about all the crap she's been forced to put up with and how she gets no appreciation for her efforts.
  • Beleaguered Assistant: For Trina, who makes her do all the things she believe she's too good for - which is to say the parts of her schemes that are dangerous and difficult.
  • Beta Bitch: To Trina, albeit of the Minion with an F in Evil variety.
  • Beware the Nice Ones:
    • In "Knights to Remember", although part of it is most likely due to the result of Bonkerton Comet, but she was still pretty scary in that episode. Specifically, the comet seemed to switch her personality with Trina's (and Trina's with hers), to the point where she took up the role of diary/lyric writer, even copying Trina's Game Face (albeit with Scary Shiny Glasses added for good measure) while doing it.
    • In "Group Hug", after Kate and Allie kidnap Trina, she threatens them into telling her where they hid her.
  • Big Damn Heroes: In "Hear Us Rock!", she pulls a Heel–Face Turn and retrieves Grojband's instruments from a dumpster.
  • Black Bead Eyes: Has these under her glasses.
  • Butt-Monkey: Possibly the most abused character on the sure, which is almost always as a direct result from Trina.
  • The Chew Toy: To Trina, who constantly abuses her. However, Mina seems to put up with it pretty well.
  • The Cameo: In "Cloudy with a Chance of Maltballs" (twice!) as a lampshade parody of Absentee Actor, since Trina tells her both times, "you're not in this episode".
  • Catch Phrase: "Bam indeed," usually in response to Trina's own catch phrase.
  • Childhood Friends: With Trina, as they've been friends since Kindergarten.
  • Cool Big Sis: To Carrie (aka "Pinky Dinky Doo").
  • Cool Bike: In "Soulin' Down the Road", she rides a motorcycle with a sidecar.
  • Cute Bookworm: As seen in "Six Strings of Evil" when Trina derides her love of books.
  • The Dog Bites Back: Gets back at Trina by standing up to her and saying that she's had enough abuse in "Hear Us Rock!".
  • Doppelgänger: To Trina, as she's pretty much a mirror image of her.
  • The Dragon: To Trina (but of the Minion with an F in Evil variety, of course).
  • Expy: You can hear a lot of Kitty Ko in her. She also has some aspects of Beth as well. Unsurprising, given Grojband was produced by many of the people behind Sidekick and Total Drama.
  • Extreme Doormat: Don't be surprised if Trina uses her as a literal doormat as well.
  • Four-Temperament Ensemble: In contrast to her foul-tempered "friend", she's more cheerful and timid, making her the Melancholic and Sanguine one.
  • Friendly Enemy: To Grojband. Despite helping Trina with all her schemes against her, she possesses no ill will to Corey and the gang and is generally a very nice girl to them.
  • Genki Girl: Usually whenever Trina's not around, she's cheerful and outgoing.
  • Hartman Hips: Like Trina, her hips are noticeably larger than her chest.
  • Heel–Face Turn: In "Hear Us Rock!". She's last seen going back with Trina again, but is now calling her out on her bad behavior and demanding respect from this point forward.
  • Meaningful Name: Combined with Stealth Pun. Beff, Be-F-F. Also notice how "Beff" sounds like "Beth"?
  • Meganekko: She's quite cute and wears a large pair of spectacles.
  • Minion with an F in Evil: Despite working with the evil-tempered and thoroughly nasty Trina, Mina is friendly, cheerful, sweet, and has no ill will to Grojband.
  • Morality Pet: To Trina. Sometimes, and only sometimes.
  • Nice Girl: In total contrast to her mean bitch of a "friend", Mina is a very nice girl who really only works with Trina because they've been friends for as long as either can remember.
  • Overly Long Tongue: As shown when Trina uses it to wipe barf off her face.
  • Plucky Girl: Especially in the episode "Hear Us Rock!".
  • Security Cling: Did this to Trina in "In-D Road Rager" and to Nick Mallory in "Creep Away Camp".
  • Smart People Wear Glasses: She's a lot smarter than Trina and also the only one of the two to wear glasses.
  • Smoke Out: Does this in the episode "In-D Road Rager" as she and Trina vanish.
  • Subordinate Excuse: She sees Trina as her BFF and goes along with her schemes because of this.
  • Sweater Girl: She wears a sweater by default.
  • Sycophantic Servant: To Trina, whom she constantly showers with praise and does her bidding without question.
  • Who Wears Short Shorts?: She wears very short green shorts.
  • Why Did It Have to Be Snakes?: She is terrified of bugs.
  • You Gotta Have Blue Hair: It's teal.
  • Zettai Ryouiki: Fluctuates between Grade C and Grade B.

    The Newmans
Left to right: Lenny/Larry Nepp, Carrie Beff, Kim Kagami, and Konnie Kagami

Voiced by: Lyon Smith (Carrie), Bryn McAuley (Lenny/Larry), Sergio Di Zio (Kim), and Tim Beresford (Konnie)

The show's secondary antagonists. The Newmans are Distaff Counterparts of Corey, Laney, Kin, and Kon who always compete against Grojband in music contests or for the various gigs they pursue.

  • Crossdressing Voices: All of them are voiced by their Grojband counterparts' voice actors.
  • Distaff Counterpart: Each member of the Newmans is a Gender Flipped version of their Grojband counterpart.
  • Gender Flip: They all look like Rule 63 versions of Grojband.
  • Identical Stranger: Despite none of them being related to one another, they all look, dress, and sound extremely similar to their Grojband counterparts. To a lesser extent this applies to their personalities as well, with the exception of Lenny.
  • Meaningful Name / Shout-Out: They're named after Newman from Seinfeld, who was the rival to the show's main characters as well.
  • The Rival: To Grojband. While they may be the better lyricists, Grojband's musical skill always comes out on top.
  • Rule 63: Canonical versions.
  • Similar Squad: Again, they're all gender-opposite versions of Grojband, with similar personalities (except Lenny).
  • Sitcom Archnemesis: If the name reference didn't tip you off.

Carrie Beff

"Well, whatever the worst burn of your life was, imagine it just got said to you. Twice!"

The lead guitarist/lead singer of the Newmans and Mina Beff's younger sister. She's more competent in writing lyrics than her male counterpart Corey, whom she has a relatively similar personality to.

Lenny Nepp (originally Larry Nepp)

"Gals, I am not built for this. And I didn't bring my inhaler."

The bassist, manager, and only male member of the Newmans (although he's often mistaken for a girl). In contrast to his tomboyish female counterpart Laney, he is very shy, soft-spoken, and cowardly. He has a huge crush on Carrie.

  • Blonde, Brunette, Redhead: The redhead to Konnie's blonde and Kim's brunette.
  • Butt-Monkey: He ends up doing terrible during the extreme curling match due to not having his inhaler. And in "Kon-Fusion", he reveals he nearly gets killed because of Carrie's ideas.
  • Cross-Dressing Voices: He has the same voice as Laney, albeit lower-pitched.
  • Dude Looks Like a Lady: Just like his Grojband counterpart, Lenny is often mistaken for a member of the opposite sex due to his appearance and behaviour.
  • Establishing Character Moment: His first speaking role in "Rock the House" characterizes him as nervous and timid.
  • Fiery Redhead: Inverted. He's the most soft-spoken person in the band.
  • Foil: In contrast to the tomboyish and confident Laney, Lenny is effeminate and reserved.
  • Lovable Coward: In contrast to the tough and fearless Laney, Lenny is shy and wimpy. However, he's still quite an endearing character.
  • Masculine Girl, Feminine Boy: The Feminine Boy to Carrie's Masculine Girl. He also has this dynamic with his Grojband counterpart Laney.
  • Nerdy Inhaler: Although not a nerd, he mentions having a inhaler in "Rock the House", which still matches his timid and awkward personality.
  • Retcon: He was initially called Larry throughout the series' run, but now goes by Lenny after Todd Kauffman renamed him as such. Even the wiki has him go by that name.
  • Saying Sound Effects Out Loud: "Sigh..."
  • Shrinking Violet: While he's comfortable performing onstage, he gets scared regarding his crush on Carrie.
  • Spell My Name with an "S": He was referred to as Larry throughout the series before his name was Retconed to Lenny by the creators after the show had ended.
  • The One Guy: For the Newmans, yet he's mistaken to be a girl (at least to people outside the band).
    Corey: Sorry to rattle you girls, but extreme curling is our world.
    Larry: I'm a boy!
    Carrie: Close it Larry!
    Larry: Sigh...
  • Will They or Won't They?: With Carrie.

Kim and Konnie Kagami

"I think they're taking this whole sharing a heart thing too far."

"Ice cream! ICE! CREAM!"
—Konnie (With Kon at the same time)

Twin sisters who respectively serve as keyboardist and drummer for the Newmans. Like Kin and Kon, their male counterparts of Grojband, Kim is the brains of the team while Konnie is the dopey but lovable brawn.


Recurring Characters

    Kate Persky and Allie Day
Allie is on the left;
Kate is on the right
"Grojband! EEEEEEEE!"
Voiced By: Addison Holley (Kate Persky) and Madelyn May (Allie Day)

Two 9-year-old girls whom Grojband commonly refer to as their "groupies". They are the band's biggest fans and eagerly help them out with any of Grojband's plans whenever the group turns to them for assistance.

  • Blonde, Brunette, Redhead: Kate is the blonde and Allie is the brunette to Laney's redhead.
  • Cheerful Children: They're almost always in a good mood and get very excited in the presence of Grojband.
  • Four-Temperament Ensemble: Both Sanguine/Phlegmatic.

  • Hair of Gold, Heart of Gold: Kate has blonde hair and is generally a very nice girl.
  • Heel–Face Revolving Door: While some episodes show the groupies as die-hard fans of Grojband, some episodes like "Cloudy With A Chance Of Malt Balls" and "Girl Fest" show them shunning Grojband in favor of some other musician/celebrity, but no matter who they're fans of, they'll always be Grojband's biggest fans anyway.
  • Loony Fans: To Grojband.
  • Meganekko: Allie wears glasses.
  • Shout-Out: Their first names are the same as the lead characters of the sitcom Kate and Allie, while their last names are the same as the last names of Kate and Allie directors Bill Persky and Linda Day.
  • Stalker with a Crush: Variable over the series, but there are instances where they rival Sierra, taken really far in "Group Hug" where they enter Corey's house at night to give him his favorite drink, before kidnapping him and the rest of his band and holding them prisoner for their Grojband Shrine, until he writes a song about them.
  • Squee!: Whenever they see Grojband, they immediately give a loud, high-pitched squeal.
  • Tagalong Kids: To Grojband, whom they occasionally assist when the band calls for it.
  • Those Two Girls: They're pretty much always seen together.
  • Youthful Freckles: Allie has these.

    Nick Mallory
Voiced by: Graeme Cornies

An extremely cool, laidback, and hunky boy without a care in the world. Nick Mallory is the subject of Trina's massive crush, and most of her life is based around pursuing him to gain his affections - which Grojband always uses to their advantage.

  • Affectionate Nickname: Trina Riffin would usually refer to Nick Mallory as "Hunky Nick Mallory".
  • Badass Baritone: Nick's voice is pretty low, but it suits his personality and appearance.
  • The Bait / Easily Forgiven: The band will sometimes put Nick Mallory in potential danger in order to get Trina to react. Nick Mallory is usually cool with Corey doing this.
  • Big Eater: While not consuming insane amounts of food, more often than not Nick Mallory is thinking of food (or how cool Nick Mallory is).
  • Big Man on Campus: Nick Mallory's the captain of the football team and a Straight A student.
  • Cargo Ship: In-universe. Nick Mallory had no problem dating Trina Riffin when her soul was in her car.
  • Chick Magnet: The girls who don't find Nick Mallory hot could be counted on one hand. Laney being one of them.
  • The Ditz: Nick Mallory occasionally gets moments of this. For example, Nick Mallory thinks zoos are supposed to be animal prisons.
  • Four-Temperament Ensemble: Nick Mallory is Phlegmatic.
  • Friend to All Living Things: Nick Mallory loves animals, and animals love Nick Mallory. Nick Mallory is also nice to every other human character, be it Trina, Mina, or the members of Grojband.
  • Full-Name Basis: Nick Mallory only refers to Nick Mallory as Nick Mallory.
  • Hunk: Nick Mallory knows that it's part of the reason why Trina Riffin finds Nick Mallory so attractive.
  • An Ice Person: Nick Mallory's coolness manages to freeze Trina in "Rock the House".
  • Inexplicably Awesome: Nick Mallory is so cool Nick Mallory can lean on nothing and will spots away with Nick Mallory's awesomeness.
  • Innocent Blue Eyes: When Nick Mallory's irises are shown.
  • Lovable Jock: Nick Mallory's one of the nicer characters.
  • Nice Guy: Nick Mallory rarely has a bad thing to say about anyone.
  • Oblivious to Love: Nick Mallory is clueless about Trina's crush on him. Or perhaps Nick Mallory isn't, and just doesn't feel the same way and acts oblivious to avoid hurting her.
  • Pet the Dog: Nick Mallory gives an apple to Trina in the episode "Zoohouse Rock". In fact every moment that Nick Mallory makes Trina go into diary mode in happiness qualify.
  • Rebel Relaxation: Nick Mallory does this a lot. Sometimes Nick Mallory even leans on thin air.
  • Reality Warper: Nick Mallory can stare away Nick Mallory's chickenpox, and as mentioned above, Nick Mallory's so cool Nick Mallory can freeze things, also Nick Mallory does not do stink.
  • Satellite Love Interest: Nick Mallory shows very little interest in Trina most of the time, plus Nick Mallory has very little purpose to the show outside of being Trina's dream boy.
  • The Stoic: Nick Mallory stays Nick Mallory.
  • Third-Person Person: Nick Mallory likes to see above.
  • Unfazed Everyman: Nick Mallory is cool with everything that happens around Nick Mallory.
    • In fact, Nick Mallory doesn't react when Nick Mallory watches Trina Riffin's Once per Episode Diary Mode in the episode "Saxsquatch".

    Mayor Mellow
"Quarantine is such a hard word to spell, but yes, for nine days!"
Voiced by: Kedar Brown

The diminutive and incompetent mayor of Peaceville. While generally not a malicious figure, he often appears as an obstacle to Grojband's plans when Trina convinces him to use his authority to thwart them in some manner.

  • Alliterative Name: Mayor Mellow.
  • Companion Cube / Momma's Boy: Keeps a picture of his deceased mother with him at all times. He even talks to it and takes advice from it (usually of the kind telling him not to do something).
  • Easy Amnesia: Suffers from this in "Pop Goes the Bubble", thanks to Trina.
  • Good All Along: As hard as it to believe at times, due to the seemingly cruel extremes he can go, there are a few moments where he is shown to genuinely mean well.
  • Heel–Face Revolving Door: Whether he's a friend or an enemy, usually depends on his mood.
  • Karma Houdini: Despite his incompetence and tendency to perform questionable acts, he doesn't get any comeuppance for it. One time, he sent a little kid to life in prison for blowing a bubble (although he wasn't himself when this happened).
  • Kick the Dog: Quite a literal example in "The Snuffles with Snarffles" where after seeing Grojband's cute cat video, the sniffling puppy that Grojband had brainwashed everyone to love, gets punted away onto the ground.
  • Mayor Pain: Of the Incompetent variety. He's a bumbling little idiot who takes advice from a picture of his mother, often overreacts to small issues, and has made more than his fair share of questionable choices for the town.
  • The Napoleon: He's not quite as mellow as his size or his name suggests.
  • Nice Hat: It also doubles as a phone.
  • Rhymes on a Dime: Though only when he is being the announcer to some event.
  • Ultimate Authority Mayor: He doesn't seem to have any kind of town council to consult with before doing anything.
  • Well-Intentioned Extremist: His biggest interest is keeping Peaceville, well, peaceful, which means it's pretty easy for Trina to convince him to try and put an end to Grojband's antics.


How well does it match the trope?
