Sparkler is a blue unicorn that was first released in Year 3 of the My Little Pony line. She has purple eyes and her hair is purple with a red streak in her mane. Her symbol is glittery blue diamonds. She originally came with a pink hair ribbon and a white moon comb.
In Year 7, there was another pony named Sparkler in the Merry Go Round Ponies line. This pony was an Earth pony rather than a unicorn and was a completely different pony who just happened to share the same name.
In 2020, a Classic Reissue version of Sparkler was released. She was a replica of the original version and her accessories included a white hair ribbon, white moon comb, and a puffy sticker in the classic design.
