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.
