When initially introduced, Starlight Glimmer is openly friendly and welcoming, both toward the Mane Six and her followers. She is also somewhat of a disciplinarian, issuing punishment to those who do not conform to her philosophies. However, she later adopts a more callous and ill-tempered persona, desperate to keep up appearances and dismissing any concept of friendship that isn't the same as her own. She is also quite disrespectful, even to royalty, as shown when she furiously silences Twilight when she tries to explain how differences can make friendships stronger.
