Trina Riffin

Katrina "Trina" Riffin is the main antagonist of the Canadian TV series mh:besttvshows:Grojband. She is the cruel and self-absored 16-year-old sister of Corey Riffin who is determined to make Corey's life miserable, ruin Grojband's gigs and date the neighborhood boy, Nick Mallory (her crush).

She was voiced by Alyson Court.

Why She Doesn't Deserve Nick Mallory

 * 1) For starters, she is mean-spirited, annoying, extremely bad tempered and has little to no redeeming qualities.
 * 2) Her reasons for hating Corey and Grojband are very unjustified, which makes her hatred even more pathetic.
 * 3) She is incredibly mean to almost everybody around her and abuses people when things don't go her way.
 * 4) She is also sadistic and insane.
 * 5) *She is also cruel around her "best friend", Mina Beff and treats her like complete garbage since she considers her a mere henchwoman of a slave, rather than a friend that helps her out in her evil schemes.
 * 6) Character Derailment: If that wasn't bad enough, she becomes increasingly more evil and sociopathic in the later episodes.
 * 7) Unlike most of the other characters in the show, her design is quite mediocre due to her having very bright pink hair, and her hips look weirdly wide for some reason. The braces don't help either.
 * 8) Her voice (while decent for the most part) can be annoying at times and grating at worst, especially when she screams.
 * 9) She has tons of unlikable moments, such as:
 * 10) *Making Mina dump some toxic waste down the sewer pipes so that she could kill them just so that she wouldn't have to listen to their music in "Monster of Rock".
 * 11) *Demanding Mina to stop making her heart beat just so she could only hear her own and Nick's heart beating while trapped in a broken elevator in "Love in a Nethervator".
 * 12) *Becoming the mayor of Peaceville and made everyone her slaves in "The Bandidate".
 * 13) *Abusing a sick dog named Snarffles and teaming up with an evil cat named Wheeliento build a laser drill which she wielded around the garage and attempting to kill Grojband and Snarffles in "The Snuffles with Snarffles".
 * 14) * She was at her absolute worst in "Hear Us Rock" by teaming up with G'ORB as they planned a betrayal on Grojband to make herself and Nick the only two living Earthling organisms in the universe while she watched the entire world die and for everyone else including Mina and Grojband as well just so that she could sit back and laugh while she dated Nick Mallory. Thankfully she got her comeuppance by Mina as she stands up to her afterwards.
 * 15) She has an obsessive and unhealthy crush on Nick Mallory to the point she's an absolute psycho for him.
 * 16) Since she appears in every episode of the show, we have to put up with her in every episode.
 * 17) Her valspeak gets annyoing very fast.
 * 18) Overall, she counts as a Mean popular girl due to all these qualities mentioned above.
 * 19) Todd Kauffman and Mark Thornton, the creators of Grojband, confirmed that she is their favourite character in the show, making her a Creator's Pet.

Redeeming Qualities

 * 1) The scenes where she goes into Diary Mode are quite entertaining to watch.
 * 2) * Some of her Diary Modes do tend to fix most of the causes and incidents sometimes, like in "War and Peaceville", it even made the background characters to stop being territorial at each other.
 * 3) Since she always loses to Grojband at the end of each episode and sometimes gets comeuppance for her actions, it can be argued she's not a Karma Houdini in the slightest.
 * 4) *She also got her satisfying comeuppance where Mina stood up to her afterwards in the finale.
 * 5) Despite how annoying her voice can be at times, Alyson Court did a good job voicing her.
 * 6) Given the she's the main antagonist of the show, it's likely that she was meant to hated due to how cruel and despicable she is.
 * 7) It's subtly implied that she wasn't always like this and used to be a sweet girl as in the special episode "Dreamreaver", we learn that she locked away her old self (known as "Katrina") away in her mind and turned evil.
 * 8) The show Grojband wouldn't be a musical without her, due to her Diary Mode being an important factor for the songs.

Trivia

 * 1) She is named after the late Canadian musician Trina Crewe.
 * 2) Trina does not remember her diary modes.
 * 3) Trina has a severe case of pupaphobia (fear of puppets), as revealed in "No Strings Attached".
