Electric Blue is a newcomer to Ponyville, and she has no memory in the beginning. She befriends a couple of well known ponies by chance, and later forms her own group of friends with the ponies she knows best, Destiny Bond, Fluttershy, Braeburn, Azure Spark and Twisha. A lot of mysteries revolve around Blue; she learns that she used to be human, she is hunted by Glais, her arch rival in the human world, and all of her past is held in a diary. Many adventures and events happen throughout the story, and Equestria gets changed by Electric Blue herself.
