Princess Ember, also called Ember, is a female dragon princess and ally/friend of Spike. She first appeared in the season six episode of My Little Pony: Friendship is Magic, "Gauntlet of Fire."

Gauntlet of Fire
Princess Ember appears with her father in the season six episode, "Gauntlet of Fire" When the dragons of Equestria are gathered together by Torch to compete for the title of new Dragon Lord, Ember tells her dad she wants to participate, but is forbidden because of her small size.

Against Torch's wishes, she disguises herself in armor and green body paint to secretly part in the Gauntlet of Fire. She almost drowns in the first leg of the race, but Spike saves her. Ember says "dragons don't do friends", Ember's views about friendship conflict with Spike's. However, she agrees to partner up with him in order to face the Gauntlet's more daunting obstacles.

Celestial Advice
Ember appears in a simulation produced by Twilight when she considers the Dragon Lands as a possible place to send Starlight Glimmer.

Triple Threat
Spike accidentally invites both Ember and Thorax to Ponyville on the same day. During her visit, Spike acts distant as he tries to keep her and Thorax apart, causing her to feel ignored. When she eventually confronts Spike about this, she gets into a brief conflict with Thorax, mistaking him for a bear that wishes to cause Spike harm. After the misunderstanding is cleared up, Ember helps Thorax to be more assertive toward his subjects, and he helps her to express her feelings in a calm manner. After she and Thorax reconcile with Spike, they both take part in a ceremony to unite dragons and changelings in friendship.

To Change a Changelling
Ember is mentioned by Starlight when she tells Thorax about her teaching him to be assertive.
