In the show, her power is notable enough to have drawn Princess Celestia's attention, and both there and in fan works she is most often proud of her status as the Princess's personal protegee. She's sometimes shown as very dependent on her books to work her spells, being unable to do more than levitate objects or teleport short distances without a written spell formula in front of her. She is also the poster-filly for the myth that complex unicorn spells are unstable and that the slightest bump or a poorly timed sneeze can end up transferring body parts, swapping genders, or teleporting ponies to lands unknown. Twilight is smart, bookish, and skilled in every type of magic there is. In Magical Mystery Cure, Princess Celestia changes Twilight Sparkle from a unicorn to an Alicorn. She is very practical and grounded, often serving as the voice of reason, though she has a tendency to freak out whenever disappointing the Princess becomes a possibility, at least, in her mind. Twilight Sparkle is a studious Alicorn, and the former protege of Princess Celestia.
