Intelligent, serious, and driven. At times, Twilight might be a little too driven. One time she throws a slumber party by declaring, "we'll do everything by the book, and that will make [it] officially fun." But while she can be a bit uptight and anxious about her work, Twilight's serious nature comes from her strong sense of responsibility to her fellow ponies. And even though Twilight might be opposed to it, her new friends might just be able to teach this serious-minded pony how to relax.
