Tori Vega (portrayed by Victoria Justice) is the younger sister of Trina Vega and attends Hollywood Arts, a performing arts high school, along with her.
When Trina experiences an allergic reaction to a Chinese herb to try to make her voice sound better, Trina's tongue gets swollen right before a big showcase at school. She is volunteered by Andre Harris to take her place, since she knew how the piece was meant to be performed as well as all the lyrics. Tori performs "Make it Shine", which is the theme song, and everyone is impressed with her performance, including principal Eikner, who offers her an enrollment to the school. She accepts it and is admitted to Hollywood Arts. Initially feeling out of place at Hollywood Arts, Tori makes new friends and becomes more comfortable. From there, the show details Tori's journey through school as she gets into unusual situations have differences and adventures with her friends. She is one of the favorite students of her teacher, Sikowitz.
She is depicted as creative, nice, caring, forgiving, responsible, positive, easy-going, and friendly, though she can be sneaky and vindictive, going as low as to manipulate her friends and family, especially her older sister, Trina, but she will always do the right thing in the end. Tori is shown to care for her friends and family a lot and is willing to help them when she is hesitant to.
Tori is friends with Beck Oliver, Cat Valentine, Robbie Shapiro, and is close to Andre. She often tries to be nice to Jade and sometimes describes Jade as her friend, even though Jade herself does not. In some episodes, they seem to be moving towards becoming friends, although most of the time, Jade seems to be "frenemies" with Tori.
In later episodes, Tori is shown to wear glasses when at home and at school she wears contacts.
She, or another student resembling her, can be seen together with Beck, Robbie, Jade or a who person resembling them in the Sam & Cat episode '#MommaGoomer', as Sam and Cat go to Hollywood Arts in order to ask Sikowitz for help.
