Awesome McCoolname: Corey Jaron Riffin, this is supported in the episode "Dueling Buttons", when he inputs the intials "CJR" in the game".
Aww, 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.
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.
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: When it comes to lyrics, but only without the use of Trina's Diary.
Easily Forgiven: By Nick Mallory. Here is a list of things Corey has done to Nick:
Pushed Nick off of a plank.
More or less forced Nick to go on a date with a monster.
"When you're in love, even doing nothing at all is wonderful."
Voiced by: Bryn McAuley
The bassist (although multi-talented), Self-proclaimed band manager, and the only female member of Grojband (although with the clothing she often wears, she's often mistaken to be a boy). Has a huge crush on Corey.
Also thanks to some punny analysis on the WMG page: of Amy Pond, as they're both Fiery Redheads who are madly in love with their childhood crushes and their names sound similar ("LaneyPenn" and "AmyPond").
Hypocrite: She has disliking to "Boy-Crazy Girly Girls" but she herself has a MAJOR crush on Corey and the show hints she has a "Girly" Side
Also she gets mad that Singer Candy Jams doesnt 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.
"Wow! Somebody must really like us!" "I bet it's our future selves!"
Voiced by: Sergio Di Zio (Kin Kujira) and Tim Beresford (Kon Kujura)
Kin: Kon's Siamese twin brother, Keyboardist for Grojband, and a genius, as he's in charge of the band's pyrotechnics, lighting, computers, and any instrumentation that is tech related and that he would also invent gadgets that could come in handy when trying to make Trina go into Diary Mode. Kon: Kin's Siamese twin brother, and Drummer for Grojband. Seems to have a Crush on Trina Riffin, whom she doesn't love him back.
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 amnesia that causes him to believe that he's a dog.
Competition Freak: She's the only Newman who takes gigs seriously, as shown in "Rock the House" and "Kon-Fusion".
Carrie: You had the hands for hours. Why aren't you writing? Corey: I don't really work that way. I just wait until inspiration hit. Carrie: Hurry up! The gig's in ten minutes! I'm freaking out! Corey: Yeah. I hear that a lot.
The show's primary antagonist, she'll stop at nothing to ruin Grojband and use their garage as her own private bedroom. She has an unrequited crush on Nick Mallory, whom she describes him as Hunky, and is biologically Corey's older sister, as well as Mr. Riffin's adopted daughter. She has a diary and Once per Episode whenever she's overcome with an emotion (whatever the emotion calls for it) she goes into Diary Mode.
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.
Hidden Heart of Gold: She has one beneath all the crazy. We even see it visibly as Katrina in "Dreamreavers".
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.
In fact 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.
It's All About Me: Taken Up to Eleven in "Here, 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.
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.
Would Hurt a Child: Possibly. In "Group Hug" after Kate and Allie kidnap Trina she pins them to the ground and demands they tell her where they hid her. Who knows what she would have done if they didn't comply.
Face-Heel Turn: 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
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.
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.
Karma Houdini: He sends a little kid to life in prison for blowing a bubble. Of course he wasnt himself when this happens.
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.
