Victorious/Awesome

"Jade: She can't play the role and I'm the understudy. Sikowitz: I don't care, you've been acting like a gank all week. I'm not going to reward you by letting you play the lead."
 * After Jade pours coffee on Tori's head during an improv sketch, the next day, Tori gets revenge by kissing her (Jade's) boyfriend, Beck in another improv sketch.
 * This made her appear as less of a likeable protagonist to some viewers.
 * Much moreso in Cat's New Boyfriend, where Tori kisses the titular boy who happened to be her ex-boyfriend. Seems like Cat and Jade can both relate with each other now.
 * And then Cat punches Tori in the face later on in the episode.
 * Maybe the writers took on board the criticism of previous characters in this universe, Carly Shay and in Zoey101 (who were regularly accused of being too perfect), and thought a character who can be selfish and a bitch sometimes would make her more believable.
 * Tori and friends taking revenge on Manipulative Bastard Ryder in "Begging On Your Knees", along with his ex-girlfriends. Seeing such a Smug Snake of a villain given a well deserved Humiliation Conga, priceless!
 * Tori does it again in "Prom Wrecker", By crowning Jade as the prom queen and Doug the Diaper Guy as prom king, as a "discreet" revenge for Jade almost ruining Tori's hard-worked Prom. And to top it all off, a song by Tori, Cat and Andre to close the deal!
 * Tori and Jade giving Robbie a much needed comeuppance near the end of "Robarazzi".
 * Sikowitz takes the cake, or should I say lead role in the play, in "Tori Gets Stuck".

"Beck: Can't blame them. Jade: Sucks to be you. Tori: Gank."
 * Tori gets a minor once for also calling Jade a gank in "Freak The Freak Out", when she explains why her parents went on vacation to avoid taking care of Trina.

"Cat: I know Robbie's rapping wasn't very good, but did you really need to throw something at him?"
 * "iParty With Victorious". When Robbie tries to rap, someone throws a plant at him, knocking him out. Cat calls everyone out on this.

"Tori: Cat, the doctors said you're not supposed to talk! Cat: (Removes head-thingy) They couldn't say I couldn't siinnggingg!"
 * It should be noted that she is promptly ignored by everyone, but still, calling everyone out on Robbie's Butt Monkey status is a pretty big accomplishment for someone like her.
 * This exchange makes her even more awesome.

"Hayley: We won, because we rock. Cat: Yeah, don't believe everything your daddy says."
 * She also called out Hayley in "Freak The Freak Out" on her rigged victory.

"Tori: I don't know, Beck looked like he was really getting beat up back there. Jade: And why would that matter to you? Tori: Well, I feel he suffers enough dating you."
 * Rex proceeding to school everyone in rap battles (except Sam, but still)
 * Cat and Jade proceeding to get Tori's help in a Batman Gambit to give the two mean girls a rather fitting Humiliation Conga was also awesome.
 * Tori standing up to Jade in "Prom Wrecker".
 * The gang proceeding to escape Yerbanian prison through the access row, then getting in a duck truck and riding across a pavement that says "NO ESCAPING".
 * Jade and Beck get special mentions for keeping their usual composures even when they know they're locked up in a hellish prison.
 * Trina putting her martial arts skills to use on  in "Helen Back Again".
 * In "Terror on Cupcake Street", Beck gets one by blasting fake confetti to scare off the thugs.
 * "The Gorilla Club" had Cat ride the flaming bunny and defeat the balls of pain with complete ease. Tori also completes the balls of pain, but the biggest Crowning Moment of Awesome of hers was defeating the Gorilla, just by doing the Hammer dance.
 * Trina gets a really, really small one in the same episode just by telling Jade to hush.
 * A small example from "The Worst Couple", but Beck is the ONLY one who could say 'You're being obnoxious' to Jade's face and get away with it.
 * Just Beck in general standing up to Jade's bitchiness.
 * Andre as well, when he goes out on them saying that the gang is sick of their fighting.
 * "Andre's Horrible Girl": Andre gets one by "sassing" Hope when she confronts him.
 * "Car, Rain, & Fire": In the B-plot, Beck was irritated when Trina told people that he asked her out (as a ploy to get guys interested in her). So, he, Andre and Robbie all play a three-way fight for her affection, then when it appears to go too far, they act like nothing happened, teaching her a lesson about lying, then just leaving her stunned.
 * "Tori and Jade's Playdate", had Tori and Jade's first duet ever, "Take A Hint", and boy, did they hit it out of the park this time. The fact that it was a "The Reason You Suck" Speech to both boys harassing and was done publicly really drives it home.
 * Thought technically it was Daniella Monet, seeing her finally sing in "April Fool's Blank" was way overdue.
 * Victorious being the second show to ever beat iCarly for Favorite TV Show (after Drake and Josh did in 2008, though that was before iCarly was big) at the 2012 Kids' Choice Awards, which at this time arguably stands out as the show's defining C Mo A.
 * In "Driving Tori Crazy", one of the girls calls Tori a grunch. Tori does not take this very well, and decides to take on all four girls in the car.
 * This exchange in "Stage Fighting".
