|“||I'm the Queen of Revenge, Jenna. I've disbanded cheer squads, ruined people's social lives, and I fucking ripped a girl's arms off! But all of that is going to pale in comparison to what I am going to do to you.||”|
Mackenzie Zales is the head cheerleader of the Overland Park Cheer Squad. She is also homecoming queen, a part-time model, a member of The Prom Committee and Candy Cane Princess. Mackenzie serves as the brains of the Cheer Squad. She is one of the most popular girls in school.
As someone who has a large status at Overland Park High School, Mackenzie’s primary interest is her appearance and status within the student body and community of Overland Park. She is not afraid to use whatever methods are necessary to ensure that she remains at the top of the proverbial food chain in high school. She does not like to concede when an adversary has her backed into a corner, such as when the Van Buren family forced her into apologizing to Shay for calling her a “fucking liar,” or when Tanya Berkowitz won against her in a battle of wits at the mall. Mackenzie also used to have a problem with her hair falling out when she got stressed or cursed. But her hair loss did eventually stop (without any explanation.)
Like a cliché "popular girl," Mackenzie is always telling people off in an aggressive and uncouth manner. In Episode 1 when she meets Deandra for the first time, she immediately brings out her instinctive rudeness and determination. While not as extreme as Brittnay, Mackenzie does have a selfish and bratty attitude, and she is not afraid of foul language. However, In Episode 18, it was announced that she is losing hair due to stress. She loses a hair each time she curses. She is now trying to keep her temper down to prevent further hair loss. Unfortunately her attempts so far have proven to be largely unsuccessful, primarily due to the intrusion of the Atchison High Cheer Squad at the Oak Park Mall.
Mackenzie is shown to have some skill for social graces and courtesy, such as when she displayed a calm and collected demeanor when offering Deandra a position on the cheer squad. However, these traits are only ever utilized when she is trying to gain support or information that will better her position.
It is revealed in the season three finale that Mackenzie was the one responsible for the destruction of Brittnay's car, claiming it was "collateral damage." This was what initiated her plan of revenge against Jenna Darabond and her "hipsterism" movement, resulting in Darabond's arrest. But because of her actions, the cheer squad starts to lose their popularity and caused Rachel Tice to rant on them for what Mackenzie had done.

Mackenize Zales looks like your typical Barbie Doll. Throughout the episodes she has only been shown wearing three outfits total in the first season. Her first outfit is shown in Episode 1 as a green and blue dress with straps that tie around her neck. As also described in Episode 1, Trisha agrees that she is really pretty. She is always seen with her hair up in a high ponytail. Her second outfit is her cheer outfit, a pink uniform with the word Park across the middle. Her third outfit is a floor-length strapless white dress that she wore to the 2012 Overland Park Prom.
The TV Producer of "Babes Having Babies" also comments that Mackenzie, like every other girl that goes to Overland Park Highschool (excluding Rachel Tice and Judith Dinsmore), is incredibly attractive.
In episode 14, a blood stain from Deandra's arms getting ripped off is still visible on Mackenzie’s uniform, and in Episode 18 there is a flashback in which she is yelling at the dry cleaners about their inability to remove blood and semen stains, holding up the bloody uniform as an example.
Throughout the series she has had a noticeable bald spot on the right side of her head. Shay was the first one to ever say anything about it in the season one finale when she says “Enjoy your bald spot, bitch.” It wasn’t addressed again until Episode 18 when she visits a doctor to find out it's FPB (Female Pattern Baldness), which she acquired through the stresses of her daily high school life. Although her FPB stopped when season 3 began.

Since then the two girls have been bitter enemies who constantly battle for social status at Overland Park. It was revealed during a viewer mail video that Mackenzie's motivation for usurping the title of head cheerleader from Shay was because Shay had allegedly eaten Mackenzie's Lunchable while she was in the restroom.The rest of Shay’s family is not seen directly interacting very much with Mackenzie.

After she won at prom her and Shay vowed to destroy her.
