Victoria "Tori" Vega is the protagonist of the Nickelodeon hit show, Victorious. She experiences the biggest change of her life during the Big Showcase when she transfers from Sherwood High School to Hollywood Arts. This enables her to learn more about her craft (acting, singing, and dancing) and make new friends and frenemies. Though she is still sometimes out of her element, she is quickly learning how things work at Hollywood Arts and really doesn't know what's coming next at the anything but ordinary school. She is one of the four main characters to appear in every episode.
In Pilot, Tori is shown helping her classmate on a science project. She then gets the chance of a lifetime to attend Hollywood Arts after taking her older sister Trina Vega's place in her school's big showcase. Andr Harris helps Tori to receive a standing ovation from the crowd, and accepts the offer. On her first day of school, she meets Cat Valentine, Robbie Shapiro, Rex Powers, Beck Oliver and her new enemy, Jade West. After accidentally spilling coffee on Beck, Tori finds herself at the wrath of Jade, who thinks Tori was flirting with Beck. After an altercation with Jade, Tori wonders if she is good enough to attend or even belong at Hollywood Arts. At the insistence of Trina, Tori returns to class and then gets revenge on Jade by winning against her in an improv assignment and by kissing Beck in front of her and ends with saying "I like this school".
In The Bird Scene, Tori wants to try out for the lead role in a play called "Moonlight Magic". However, according to Erwin Sikowitz, she must master a monologue known as "The Bird Scene" before she can be involved in any school production. She also needs to think of a creative and meaningful way to decorate her locker, which is a Hollywood Arts tradition. Sikowitz fails her twice but she then insists that she worked her hardest on the monologue, causing her to pass. He tells her that the moral of the scene is to believe in her own choices as an artist and decorates her locker with the song "Make It Shine", the same song that got her into the school.
In Stage Fighting, Jade and Tori act in a fight scene, but things go bad when Jade acts as if Tori hit her in the eye with a cane. When she explains that she did not hit Jade, no one believes her. Later it is revealed by Andr that Jade was faking it, with makeup that made her eye look like it was bleeding and made it look like she had a black eye as the aftermath. The two finally agree to play nice and trick the security guard into thinking they would finish Tori's punishment for cleaning up after a food fight scene.
In The Birthweek Song, Trina's "birthweek" arrives and Tori can't decide what to get her as a gift. After Andr suggests a song, they write "You're The Reason" and they perform it at Trina's party. Despite a successful performance, Trina, however, does not think it is a very good present since Tori did not spend money on it. Trina then brings the song to a record company but the producers find out that she isn't the real singer and unsurprisingly, she is bad at it as well. She then records the song with Andr, causing the producers to like her more than Trina, and learn that R&B artist Beyonce liked the song, leaving the three behind.
In Tori the Zombie, Cat uses Tori as her assignment for a makeup class, which is to make someone look horrific. Everything turns out wrong when she makes a zombie mask with cement glue and it gets stuck to Tori's face. It causes problems when Tori tells her that she is the lead role of a play and is supposed to look beautiful. She sends Trina and Cat on a drive to get the cure from the salutation. Because of them, she is forced to perform with the makeup on. Though the two arrive very late, the play's original writer, Sofia Michelle, praises Tori's performance, even complimenting the zombie mask as a way of showing that true beauty is within.
In Robarazzi, after Tori helps Robbie improve his blog on "TheSlap" and help make it become more popular, he begins filming the personal lives of his friends for his blog called "Robarazzi." When he starts going overboard, Tori masterminds a plan to give Robbie a taste of his own medicine.

In Wi-Fi in the Sky, Tori and Trina's flight home gets delayed, so a stressed-out Tori uses web conferencing to work on a group project for school with Andr, Cat, and Beck while she is on the plane. While attempting to get it done, the rest of the group keeps getting distracted by many other things around them.

After being allowed to join and not give them away, she dines at the restaurant with the gang. Tori is shocked that their check is $1,300 because of Robbie ordering too much caviar as it is a very expensive ingredient. Learning that the restaurant has been lacking performers, she saves them all from being arrested with a performance with Andr.

While they are hanging out, Jade and Cat are challenged by two girls Hayley Ferguson and Tara Ganz to a sing-off. Hayley and Tara sing "Number One" by Ginger Fox but the HA gang is surprised to hear how bad they sing. Cat and Jade counter with "Give It Up" and show the crowd that they are the better singers. Despite Cat and Jade singing very well, the competition is rigged and Hayley and Tara win because of Hayley's dad being the owner. After getting cheated out of the win, they go to Tori for help and they come up with a plan to upstage Hayley and Tara. Cat and Jade place a bet on the two: if Hayley and Tara win, she can make out with Beck but if they lose, they have to take care of Trina. Tori goes in disguise as "Louise Nordoff" in order to trick the two into continuing their win streak. Cat and Jade, knowing that is Tori, tell the girls to not pick her but they insisted. During the performance, she removes the disguise and reveals that she isn't Louise, but Tori Vega herself. Everyone at the club including Hayley and Tara is surprised except for Cat and Jade, who already knew it was her and that Jade devised the plan. She wins the singing contest, Jade's revenge plan is successful and that her and Cat's ban is lifted.
