Cosmic Melody has been cosplaying since her very first Bronycon in 2012. Since then she has appeared at several pony conventions as a plethora of characters, notably, Princess Luna, Midnight Sparkle, and Adagio Dazzle. Cosmic Melody is also a part of the regular cast of the Semi-Perfect Podcast. At Ponyville Ciderfest you can probably find Cosmic Melody spending an irresponsible amount of money in the vendor hall.
