Princess Cadance, also known as Princess Mi Amore Cadenza, (voiced by Britt McKillip) is a pink alicorn, niece of Princess Celestia, and wife of Twilight Sparkle's brother Shining Armor. During Twilight's childhood, or fillyhood, she was her foalsitter. She's considered by Twilight to be "the greatest foal-sitter in the history of foal-sitters," as Twilight remembers Cadance as someone who would greet her with a hug, bandage her and wipe her tears when she's hurt and play with her on a swing set. Twilight and Cadance also used to do this little hoof-shake dance together. Cadance eventually became Twilight's sister-in-law after she married Shining Armor.
Her special talent is to spread love wherever she goes.
