Andre Harris (portrayed by Leon Thomas III) is a sophomore and Tori's best friend and mentor at Hollywood Arts.
It is revealed in the episode 'Wok Star' that Robbie is Jewish because he spent his Bar Mitzvah money on leather pants and male make-up.
In 2011, Rex's in-universe actor Christopher Cane hosted a bloopers episode of Victorious titled "Blooptorious" in which he interviewed cast members and showed outtakes from the series.
She has a gothic sense of style—always wearing dark clothes with eyebrow piercings and different colors of streaks in her hair, and is the long-time girlfriend of Beck Oliver.
In "Ice Cream for Ke$ha", it is revealed that her childhood was a dark and unhappy one, her favorite play toy being a hammer and scissors, and that she had been raised by an unsupportive and similarly emotionless father and a mother she could not emotionally connect with.
Catarina "Cat" Valentine (portrayed by Ariana Grande) is a sophomore and is Tori's eccentric friend from Hollywood Arts.
It was also revealed by Robbie in "The Blonde Squad" when he yelled "Catarina Valentine, I will not sit here anymore and listen to you talk bad about yourself!
Her parents couldn't take her as it was in the middle of the school year and wanted her to stay in Los Angeles and sent to her Uncle Walter and Aunt Pearl, while they are in Idaho but according to Cat, they are very strict and mean.
This caused Cat to run away and take refuge in the attic of Hollywood Arts' BlackBox theater, where her living habits were discovered by Robbie and Jade.
He has been together with Jade for over two years and, unlike everyone else, is completely unafraid of her (even laughing when Andre admitted to being scared of her) and often likes to tease and make her jealous because of her reactions, which he finds amusing.
Because of his good looks and personality, he is possibly the most popular guy at Hollywood Arts and attracts almost all females and girls like Trina, sometimes even older women.
Trina Vega (portrayed by Daniella Monet) is a junior/senior and is Tori's vain older sister, who also attends Hollywood Arts.
Trina believes that her natural acting and singing will get her into any doors in Hollywood and make her a global star, while being very oblivious to the fact she has 0 talent.
It's revealed that when Trina was an incoming freshman, Sikowitz was the one who voted her into Hollywood arts, while under the effects of an expired fruit, not realizing she was terrible.
Trina's personality shows that she's quite selfish, self centered and shallow most of the time and is portrayed as being extremely difficult to deal with, sometimes even being called a "monster".
Sinjin Van Cleef[8] (portrayed by Michael Eric Reid) is a strange and questionable student at Hollywood Arts.
He is nerdy, disturbing, and very weird, often considered stranger than even Robbie or Cat; his locker has his chewed up food on it and he also likes to collect the teeth of past presidents' relatives.
He is also skilled in computer science, to the point of being able to hack into a private server to delete an embarrassing picture of Jade in "The Bad Roommate".
It is revealed in "A Christmas Tori" that he has a sister named Courtney (played by Dominique Grund) who also attends Hollywood Arts.
His habits might be interpreted as weird and his methods are shown to be often very strange (including throwing a ball at Cat while she is performing), but at times very effective.
He also gave Cat, Jade, Beck, Andre, and Robbie permission to start a fake ping-pong team to make money and have a fancy dinner.
As strange as Sikowitz is, he is the favorite teacher of Tori, Cat, Jade, Beck, Andre, and Robbie, and is very open and comfortable with them, to the point he says that he is their friend in a few episodes.
In one episode when Tori goes to him asking for help, he is hanging upside down from the ceiling, and in another, he stored his grandmother in the corner before slinging her over his shoulder and taking her to the hospital.
After Goomer confessed to his mother that he is an MMA fighter, Sikowitz uses an electric shaver to get the fake pit hair off of Dice's armpits claiming that he grew them too soon.
Lane is the one who made a reality television series, The Wood, leave the school because it was becoming an issue with the students and disrupting the learning environment.
He tends to be a bit extreme in his dealings such as when he issued a two-week detention to Tori for a supposed accidental hit on Jade during a stage fighting practice, made Robbie and Trina cover for Festus after accidentally injuring him, and having Tori and Jade take Festus home after unknowingly wrecking his car which was similar to one of the janitors' car.
Andre tells Tori in the "Pilot" episode that her coming to see Trina perform "Make it Shine" is the first time in six years that she has left her house.
He also mentions in "Survival of the Hottest" that before she lost her mind, she used to tell him, "Andre, no matter how bad things get, you can always make it better by singing a song".
Mrs. Lee returns in the episode "Andre's Horrible Girl", now operating a Sushi bar called Nozu after Wok Star "mysteriously" burned down in an accidental fire.
She later appears in the third-season episode "How Trina Got In", making Tori and Robbie chop a pile of squid after they cannot pay their bill.
