Thistle is a pegasus pony who was born and raised in Cloudsdale, moving to Ponyville with her friend Flash after her parents moved.
Like most pegasi, Thistle's life began in the skies above Ponyville, in Cloudsdale. Being an only child, she spent a lot of time with her parents and developed a close relationship with them. She had a few "buddies," you could say, but she had only one true friend: Flash.
Thistle and Flash were friends from the time they first raced against each other. From that time on, the two were inseparable. Sadly, they were pulled apart when Flash's family moved to Ponyville. After that, Thistle visited every weekend. When her own parents decided to move from Cloudsdale, Flash invited her to stay with him, and that is where she is to this day.
Thistle is a relatively shy pony, though she is very fun and open with those she knows. She dislikes too hot or too cold weather; she prefers autumn type of weather, which is where she gets her cutie mark from.
Like most pegasus ponies, Thistle's magic revolves around the weather.
Thistle recieved her cutie mark due to her work during the autumn. After the majority of the leaves have fallen, Thistle always goes and blows them out of everyone's way. She then takes what leaves she's collected and makes large piles for the young fillies and colts to play in.
