Medley is a Pegasus pony. She is Firefly's more level-headed friend. She tends to worry a lot.

She was seen sliding down on the rainbow with Firefly at the start of Rescue at Midnight Castle.

She stayed behind in Dream Castle while Firefly, Twilight, Bow Tie, and Applejack go with Megan to rescue the other ponies that were taken to Midnight Castle.
