Sparkle family

The Sparkle family are Twilight Sparkle's relatives in My Little Pony Friendship is Magic.

Parents
Twilight's mother and father are respectively named Twilight Velvet and Night Light. They first appear in a flashback in The Cutie Mark Chronicles enrolling a filly Twilight in Princess Celestia's School for Gifted Unicorns, and Twilight accidentally turns them into plants during her entrance exam. In The Crystalling - Part 2, Twilight Velvet and Night Light have speaking roles and are respectively credited as Mrs. Sparkle and Mr. Sparkle.

Twilight Velvet's mane and tail bear a slight resemblance to those of her daughter Twilight Sparkle, and she strongly resembles Lauren Faust's original concept art that was based on G1 Twilight. Night Light shares Noteworthy's color scheme, and appears to be visually based on the G1 German release Rainbow Pony Nachtlicht.

Siblings
Twilight's older brother is named Shining Armor. He first appears in the season two finale A Canterlot Wedding as the captain of the royal guards and Princess Cadance's husband-to-be. Prior to his debut, Shining Armor was announced as a part of the then-upcoming Pony Princess Wedding Castle toy set, which comes with him and Princess Cadance.

Princess Cadance
Princess Cadance first appears in the season two finale as Shining Armor's fiancée. She was Twilight Sparkle's beloved foal-sitter when she was a filly, and the two share a special handshake with the accompanying rhyme: "Sunshine, sunshine, ladybugs awake! Clap your hooves and do a little shake!" Through Cadance's marriage to Shining Armor at the end of A Canterlot Wedding - Part 2, she and Twilight become sisters-in-law.

Flurry Heart
Flurry Heart is Shining Armor and Princess Cadance's Alicorn baby and Twilight's niece. She is announced by Shining Armor and Cadance in The One Where Pinkie Pie Knows and introduced in the season six premiere The Crystalling - Part 1.

Miscellaneous
In A Canterlot Wedding - Part 1, Shining Armor mentions he has a "favorite uncle" and wears this uncle's badge at his wedding.
