Now that we've met the main cast, let's take a look at some of the supporting characters. Meet Lil' Cheese, Amethyst, and Firefly!

Meet Cheese Pie--or Lil' Cheese for short! Hyper, fun-loving, and a total center of attention, he's the son of Pinkie Pie and Cheese Sandwich, and the older brother of the infant Sprinkle Swirl. Growing up, he was bullied for his flamboyance and feminine appearance, but he has since learned to embrace himself and spread joy wherever he goes. When he meets Amethyst and Firefly, he takes it upon himself to help them on their path through self-discovery, and also provide them with all the laughs they could need along the way, of course.

Meet Amethyst! Savvy, fashionable, but a bit spoiled, she's the daughter of Rarity and the younger sister of the teenage Moonberry. When her parents divorced, Rarity decided to leave Manehattan and move back to Ponyville, which came with much dismay from her daughters. Back in Manehattan, Amethyst was the most popular girl in her school, but used her wealth and attitude to cover up her insecurity for not having a cutie mark yet. She didn't think she'd take to Ponyville at all, but finds herself acclimating quickly once meeting her new friends and finally starting to feel like her true self.

Meet Firefly! Kind, bookish, and a bit timid, she's the adopted daughter of Rainbow Dash and Applejack. When School of Friendship teacher, Ocellus, discovered an abandoned pegasus foal outside the school, she wasn't quite ready to take care of a baby herself, but she knew just who to reach out to. Firefly might not be much like her parents, but the family is still close-knit and very loving. She is a lot like her mentor, Ocellus, however, whom Firefly considers a big sister since she's always been very involved in her life. However, even with all the love and support of her family, Firefly still feels unsure of herself. That is, until she meets her new friends and discovers who she's meant to be.

I decided to introduce some new characters throughout the episodes, so here are the characters that fill the sort of CMC role in the FlurryVerse.
Firefly is based off of the OG Firefly of course, but since Rainbow Dash's personality is based off that Firefly but she took the model of the OG Rainbow Dash that used to have the complete opposite personality of her, I decided to do the same with Firefly and flip it!
Also I didn't feel the need to name Amethyst and Moonberry's father but I'll probably think of it later on. He's not that important to the story, though.
