Ember

Princess Ember is a female dragon and supporting character who first appears in the season six episode Gauntlet of Fire. She is the current Dragon Lord of the Dragon Lands, succeeding her father Torch.

Development
The name "Ember" was previously used for a G1 Earth pony filly, whom foals such as Apple Bloom were inspired by.

Season six
Princess Ember is introduced in the season six episode Gauntlet of Fire as the daughter of Dragon Lord Torch. When Torch gathers the dragons of Equestria together to compete for the title of new Dragon Lord, Ember expresses a desire to participate, but her father forbids her due to her small size.

Against Torch's wishes, Ember disguises herself in armor and green body paint and takes part in the Gauntlet of Fire. She nearly goes down in the first leg of the race, but Spike saves her from drowning. Believing that "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.

After making it through several parts of the race together, Ember and Spike's views about friendship diverge again when he risks his well-being to save Rarity. As such, she ends their partnership and continues on by herself. Near the end of the race, however, she saves Spike from Garble and accepts him as her friend. Spike wins the Gauntlet of Fire, but he quickly passes on the title of Dragon Lord to Ember.

In a final verbal confrontation with her father, Ember declares that there is more to being a leader than size and strength. Torch comes to understand his daughter's sentiment, and Ember is crowned the new Dragon Lord. As part of her new position, Ember establishes friendlier dragon/pony relations through Princess Twilight Sparkle.

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

In 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.

The Elements of Harmony Vol. II guidebook
''DRAGONS are mystical, flying lizard beasts that come in many different sizes, shapes, and colors. They have magical fire breath and spend their time munching on gems when they're not looking for a nice cave to take a nap in. While younger Dragons like Spike are sweet, others can be temperamental. Some are downright evil, like DRAGON LORD TORCH. He's the father of PRINCESS EMBER, who now serves as a kinder, gentler Dragon Lord.''
