Smolder is an Equestrian dragon who is introduced in the premier of Season 8 of My Little Pony: Friendship is Magic, and later the episode Molt Down where she explains to Spike when he struggles with a series of bizarre symptoms that is something all dragons go through in adolescence referred to as "the molt." to Spike's horror and an unfortunate "molt side-effect" that compels a molter's family to kick them out of the house. She also becomes one of Twilight Sparkle's new students in her new school. She is also revealed in 'Sweet and Smokey' that she is Garble's younger sister. She is a gruff dragon with just as much a grump as any other Equestrian dragon and is voiced by Shannon-Chan Kent (Diamond Tiara, Wallflower, and Pinkie's singing voice).
Role in the series
Due to the leaked footage, Smolder appeared early in the episode Draconequui Wonderland with Gallus, Ocellus, and Silverstream as four of the first customers of Mischief, Maleficence, and Strife. Her relationship with Garble is even expanded upon in Dragon Developments as he was lost by Smolder's parents and became the assistant of Sunset Shimmer, and she was born after this loss. After getting kicked out of the School for Gifted Unicorns, he was later kicked out again after his molt effect, worsening his attitude as Smolder wanted to help him, but hid the fact they were related after learning he and his gang were part of Team Nefarious.
