To improve my drawing, I tried to multiply the possible universes to designate the characters
 
1) Twiluniverse (Twilight is an Alicorn)
 
Toe Tapper met Vidala Swoon in the “Breezy” hair salon. As soon as he entered, it was love at first sight and the two ponies met very quickly. The current passed very well and a few years later, a small filly landed in the family. This one was named Sweet Song and was born to sing ! Her musical talent led his father to integrate him into the Ponytones, which were beginning to be successful.
 
2) Bluebelleuniverse (R63)
 
The famous opera singer, Mezzo-soprano, breaks many hearts with her voice and beauty. On tour through Equestria, Mezzo-soprano has no time to lose with a romantic relationship and prefers to devote herself to her career.
 
3) Sunsetverse (Sunset Shimmer became a princess before Twilight)
 
Although the Ponytones never had a great career, Toe Tapper and Torch Song continued the group without the other members, who took other paths in life. Of course, they eventually got closer and a colt was born of this union and was named “Gospel blues”. Although his talent is not related to music, Gospel blues loves to sing with his parents at every performance.
 
4) Chrysaluniverse (Chrysalis, reformed, leads Equestria to the side of Luna)
 
The young unicorn Toe Tapper was a father very early, after a party where the Ponytones were invited. He met Sweet Pepper a dynamic earthly woman and after a rather pleasant night, he learned that she was waiting for a filly. When she was born, he named her “Jazzy Bop”, hoping she would like music. Unfortunately Jazzy Bop prefers adventure and finds her father’s life boring, preferring to live with her mother.
 
5) Noprincessuniverse (The Alicornes don’t exist)
 
The pegasus Toe Tapper moved very quickly to the Kingdom of Crystal, in order to live there quietly, far from the celebrity of the Ponytones that he had finally left because of his break with the pegasus Torch Song. However, when he arrived in the Empire, he was immediately welcomed by the pegasus Ivory Rook, with whom the current passed very well. Years later, the two pegasus ended up moving in together, while adopting a small pegasus named Smoky Quartz.
 
6) Eviluniverse (The bad guys lead Equestria)
 
The villains have won. Twilight has never been alicorne and the princesses are no more than prisoners. The earth pony, Toe Tapper is part of the “cleaners”, led by the famous Rarity, which must maintain the castle of Nightmare Moon.
