Katrina "Trina" Riffin is the main antagonist of the TV series, Grojband. She is the 17-year-old sister of Corey Riffin who is obsessed with destroying Grojband and hates it with a burning passion. She appears to have violent anger-management issues, which Grojband uses to write good lyrics for the song they perform at the end of the vast majority of the episodes. They enrage her, causing her to go into Diary Mode, and she writes in her diary where Grojband then steals her diary from her and puts her words into lyrics.
She is voiced by Alyson Court.
Concept Biography
Trina is a cruel, stuck-up, and rude 17-year-old girl with anger issues who holds a huge hatred towards her brother Corey and his friends. Often she tries to go out of her way to destroy them. She thinks that his band is annoying and nothing more than a waste of garage space that she could be using as her own bedroom. Outside of her relationship with Grojband, she has no friends except for her friend Mina towards whom she acts very abusive and mean. Trina also has a secret crush on a boy named Nick Mallory that she always tries to make him fall in love with her, but she never succeeds at this (mostly related to Corey and the band ruining this for her). Whenever Trina gets angry enough, she takes out her anger by writing in her diary where she jets up into the air on a geyser of flames and lava before she writes in her diary, which causes flames to come out of her pen (this is called Diary Mode). Trina is unaware of the fact that she does this as she forgets it every time she exits diary mode. She is also unaware of the fact that Corey is always stealing her diary and using her diary entries for lyrics, even though he insists that he uses them for inspirational purposes only.
Early Childhood
Trina and her brother Corey Riffin were biologically related brother and sister who were both adopted by a single father when they were toddlers. When they were raised, Trina went by her full name "Katrina" and she loved her brother very much. It is unknown when she started going by the name Trina or why and when she started to hate her brother the way she does, but her time of liking her brother was quite short-lived as seen during a flashback in "Indie Road Rager." during the flashback, she displayed hatred towards Corey, even when they were little kids. In "Bee Bop A Loofah," there was a flashback, showing an earlier time in their life. The flashback showed Trina and Corey taking a bath together. Trina was looking at Corey with a smile on her face, until Corey screamed a lot and splashed a bunch of soapy water at her while playing a toy guitar, making her cry. This could mean that Corey caused Trina to hate her by being obnoxious. It would seem unlikely that Corey was intentionally annoying her because, in this flashback, all he was doing was singing and playing his guitar. In the flashback from Indie Road Rager, it was revealed that Trina had a stuffed animal named "Mr. Mooseface" which she used to keep herself safe while she was sleeping. In the episode "No Strings Attached," a flashback of Trina showed her about the same age she was in Bee Bop A Loofah, where she was seen being very happy and obsessed with toys like most little girls are. It was revealed that when she was a little girl, she went to the toy store where she was traumatized by some demonic puppets which caused her to develop a fear of puppets that she still has today. Trina was shown to be very happy in these flashbacks.
Prepubescent Years
It was shown in the episode "Dreamreaver Part 2" that sometime during Trina's preteen or early teen years, Trina was actually a very nice girl who went by her full name "Katrina" who wore her hair in braids. No actual flashback of this was seen, nor was the physical form of this girl. What was shown was a visual representation of the form of her that lived inside of her Dream World. Katrina loved Corey with all her heart and she was nice and caring to him. Her relationship with Corey was almost the opposite of what it is currently. Corey liked Katrina, but she would sometimes embarrass him by expressing her love for him in front of his friends, or he would get annoyed with her touching him, etc. So during this time, Trina was the nice one and Corey must have hated her. Corey didn't actually express any hatred in this visit with her. It was more of some small anger and negativity, so it's not too likely that Corey actually "hated" Trina the same way she hates him today. Something must have happened to her before she was 16, which caused Trina to get rid of this nice personality and become very mean and hateful to Corey. However, so little was explained about Katrina, that it is completely unknown what it was. If it wasn't an event of something traumatic that occurred around this time, then it can be said that it was because she started going through puberty at this time, and her hormone changes are what caused her to start being more trigger happy and hateful of her brother and so she repressed the good side of her personality, explained through a subtle metaphor hidden in Trina's dream world, where Katrina was seen as a prisoner, locked in the dark, abandoned prison of Trina's dream world. Without question, it's safe to say that this happened after the hatred for Corey developed in her early childhood, so this must have been a temporary phase she went through. It's also excusable that Trina and Corey were 4 or 6 years old in those earlier flashbacks, where it is very common for brothers and sisters to get really mad at each other and fight over very small things. Overall, Trina could possibly be going through the same stages of life all kids go through, but its effect on her is much stronger and way more powerful than it is with most people.
Trina is a tall, slim teenage girl who has long bright pink hair and pink eyes, an upside-down raindrop shaped head and thick black eyebrows. She wears braces (sometimes music hurts them), a white t-shirt, a short purple skirt, pink capris leggings, long white socks and dark purple shoes. She also wears eyeliner.

Corey Riffin
Corey is Trina's younger brother. Trina hates Corey, his band, his music and everything about them. They have a very bad sibling relationship as Trina is generally extremely rude to Corey and constantly goes out of her way to ruin something good for him. Corey knows that Trina has anger issues and occasionally annoys her because he enjoys making her mad. Also, Corey is always in need of lyrics for a song so he is always tempering with Trina's emotions to make her freak out and go into Diary Mode so they can steal her diary and turn her diary entries into lyrics for their next song. If it wasn't for Trina's rage issues and angst-filled diary entries, the band's lyrics wouldn't be any good. Trina is oblivious to how they use her for lyrics and it is unknown if she even remembers her diary modes when they happen. None the less, Corey and Trina have a sibling rivalry of which Corey is on top of.
Kin Kujira
Trina hates him and all of his stupid "Geekiness." She hates how he's a nerd and how he is a member of her most hated band in the world, Grojband. Like she does with most people, Trina will sometimes make Kin unhappy just for the heck of it. She is annoyed with how much of a nerd he is and she will also destroy his inventions just to annoy him as seen in the episode Ahead Of Our Own Tone as she destroyed his time machine while he was using it by smashing it with a guitar. She is also annoyed with his "nerding" as seen in Smash Up Terby when she pointed to him and told him that he wasn't allowed to "nerd" in her car. Sometimes, she will go out of her way to make Kin's life miserable for no reason. In the episode Grin Reaper, a picture was seen of Trina smashing Kin's ice cream on his head.
Kon Kujira
Trina hates him because he's fat, eats too much food, farts a lot, and is a member of Grojband, yet he is in love with her and thinks she's cute. Trina is disgusted by him and treats him like an object. She always refers to Kon as an "it" as seen in the episodes Smash Up Terby and Hair Today, Kon Tomorrow. However, in the episode Math of Kon, Trina screamed Kon's name before she went into Diary Mode.

Trigonometrina
In the episode Math of Kon, Trina was revealed to have a secret alter ego called Trigonometrina. Trigonometrina is expressive of Trina's inner personality of a nerdy, math geek. What Trina did was dress up like a stereotypical nerd and change her hairstyle and clothing and wear big glasses over her face and go by a different name so that nobody would know Trina's secret. She was really good at keeping this secret from everyone and not even Mina or Corey knew about it. Trigonometrina was best friends with Mina and when she interacted with her, she was very nice to her and she would go along with the things she did and not get mad at her like she usually does. At the end of the episode, Corey figured out her secret and revealed to everyone that Trigonometrina was really Trina in front of the entire school. Trina was extremely humiliated by this and she freaked out so much, she went into diary mode and passed out, despite the fact that everyone was cheering for her. Because of the events of this, it's unlikely that Trina still uses this alter ego.
Quincess Trina
In the episode Dreamreaver Part 2, within the confines of Trina's mind, Trina was shown to have a magical dream world where herself was portrayed as a beautiful and beloved, goddess-like queen/princess who rules over all of the dream world named Quincess Trina. This alter ego was never expressed outside of herself, but it was expressive of her aspirations and ambitions of popularity in the world.
Katrina
In the episode Dreamreaver Part 2, Grojband went inside of Trina's mind and found a repressed personality of her's locked away in the prison deep down in her mind. This was a girl named Katrina who served as an inner side of her personality. Katrina was a girl who was treated like a criminal in Trina's dream world. She is a human representative of Trina's nice side of her character which she never lets out. Katrina was a girl who really loved Corey and would be respectful and joyful about everything. She was even respecting Quincess Trina when she locked her in prison as she was seen refraining from escaping even though she could do it whenever she wanted because of her obedience. It wasn't until Corey and the band came along, who made her become more rebellious and escape prison, making her stand against Quincess Trina and Mirage Band as well as aiding Grojband in taking down Quincess Trina's empire. This alter-ego was expressive of Trina's personality from a long time ago. When Trina was younger, she was nicer and went by the name of "Katrina" and she loved her brother and was nice to everyone. Some unexplained event that occurred at some point in her life must have demented her personality and made her become the angry, hateful egomaniac who we know her as today. Trina compressed this nice personality of her's because of this and always unleashed her inner evil to make herself popular. Since then, Katrina has been contained in a dark prison so that she doesn't ruin her popularity.
•Trina has the power to warp reality via emotions (called Pathifery) because she's a demigod.
•Although she was born 3 years before her brother, due to the events of "Ahead of our own Tone," Trina is currently 4 years older than Corey.
•It is a running gag in the show for Trina to get extremely emotional over something which is mostly caused by Grojband which makes her jump into the air on a geyser of flames and she will angrily write in her diary while heavy metal music plays. This is called Diary Mode and it is how Grojband gets lyrics for their songs.
•Another running gag affiliated with Trina is for Trina insult Grojband by using a play on words to deface the name of their band when she addresses them. For instance: In Smash Up Terby, she addressed them as "Garbageband", in Monster of Rock, she addressed them as "Sewageband", and in Zoohouse Rock, she addressed them as "Grrrageband."
•Trina does not remember her diary modes.
•Trina is both Todd Kauffman and Mark Thornton's favorite character.
