Lemon Zest is a female human and one of the Crystal Prep Academy Shadowbolts in My Little Pony Equestria Girls: Friendship Games. In the film's closing credits, she is miscredited as Lemon Tart.
Lemon Zest demonstrates the behaviour of a wild, obnoxious rocker girl. She enjoys listening to loud music on her headphones and forces Twilight to listen to it at one point. Like most of Crystal Prep's students, Lemon Zest is fiercely competitive and obsessed with proving her school's superiority over Canterlot High School through any means necessary. Despite this, she happily socializes with Canterlot High's students during Pinkie Pie's party, and she later helps save several students from both schools when Midnight Sparkle's rampage puts them in danger.
- Lemon Zest made her first appearance in The Rainboom's Adventures of Thomas and The Magic Railroad.
- Lemon Zest will guest star in Doctor Aaron's Adventures of I, Robot.
