Trixie Lulamoon

She has a very theatrical personality and speaks dramatically in the third person, posing and setting off fireworks to complete the full effect.

 

Twilight Sparkle's positive, helpful, and humble attitude is contrasted by Trixie's over-the-top boasting and arrogant nature. Trixie claims to have saved Hoofington from an attack by an ursa major. However, when confronted by an ursa minor, she admits that her tale was fabricated and that even the ursa minor was an opponent far too powerful for her to contain. Despite this brief display of honesty and fear, her frequent showboating alienates the other ponies and classifies her as an antagonist.

 

Trixie returns with her magic augmented by the Alicorn Amulet. She shows no qualms about using innocent ponies to prove her power, nor does she seem to care when a spell nearly takes out another. As she ruled over the town while in possession of the amulet, she has Mayor Mare trapped in a cage, forces other ponies to do manual labor for her, and claims to not "trust wheels." She was also easily manipulated by Twilight Sparkle into a rematch duel so she could prove that she was still better, which eventually lead to her downfall. However, upon removal of the amulet and the loss of her power, she accepts her defeat against Twilight, unlike her first visit to Ponyville, and meekly seeks forgiveness for how she treated her and her friends.
