Lyra Heartstrings, occasionally called simply either Lyra or Heartstrings, (voiced by Britt McKillip and Ashleigh Ball) is a female unicorn pony who frequently appears as a background character and occasionally in more prominent roles. She has a magic mint coat, brilliant cyan mane and tail with a white streak, sunglow eyes, and a cutie mark of a lyre. The word "heartstrings" refers to deep feelings of love or compassion and is commonly used in the phrase "tug at the heartstrings" which means to cause strong feelings of affection or sympathy.
