Princess Lilly Sparkle Rose

Princess Lilly Sparkle Rose (Also known as Lilly Sparkle Rose, Lilly Sparkle or Princess Lilly) is the future daughter of Princess Twilight Sparkle. She does not appear in the story but is briefly mentioned by Violet.

She is described as "The most cheerful and energetic foal she's ever seen" and apparently travels to the human world with Twilight to see how The Main Six and co. are in the future. She is around the same age as Violet and was born around the same time too, and the two get along well.

Trivia

 * The original character actually belongs to the creator's friends' older sister, whom allowed her to be used in her sister's stuff and her sister and her said it was fine for her to be canon in The Story Of Mew Lucy.
 * She gets all her looks from her mom, so it's hard to tell who her father is.
