Zelda, Princess of Hyrule, best known simply as Princess Zelda is a member of Hyrule's Royal Family and plays an integral role in the history of Hyrule. Though she is the titular character, the player takes control of the protagonist, Link. Usually, Zelda is in some way kidnapped or imprisoned by Ganondorf. In some games she appears as one of the sages or as a prophet.
Similar to Link, Zelda has had multiple incarnations throughout the series. Generally close to Link in age, she is most often portrayed as a child, but she has been portrayed thrice as an adult, in The Legend of Zelda: Ocarina of Time, Zelda II: The Adventure of Link, and The Legend of Zelda: Twilight Princess.
Zelda is depicted as a kind and benevolent ruler. As the holder of the Triforce of Wisdom, Zelda is wise beyond her years and intelligent enough to rule her people. She always wishes to do what is right for her people and is extremely self-sacrificing. Though she is not always capable of defending herself or her people on her own, she is willing to use any means necessary to aid her allies to achieve those ends, no matter the cost to herself.
Zelda is portrayed as a young girl or beautiful young woman, usually with blonde hair, although in The Legend of Zelda: Twilight Princess, she is portrayed as more of a brunette. (Her hair is slightly darker yet in Super Smash Bros. Brawl, her appearance in which is otherwise based on that in Twilight Princess.) She also is portrayed with auburn or red hair in Zelda II, and light brown hair in A Link to the Past. She often wears a royal gown of white, pink or another pale color (red in Zelda II), usually bearing the Royal Family's crest, and jewelry such as ornate earrings.
Associated with the Goddess Nayru and the Triforce of Wisdom, Zelda possesses keen insight and good judgment—although this does not always aid her in avoiding capture. Most of Zelda's incarnations are also gifted with innate psychic or magical powers, such as telepathy and precognition. Although her full range of abilities is yet to be revealed, Zelda can cast spells and create or annul barriers and seals. Zelda's alter egos appear to have specialized abilities of their own. In Twilight Princess, she wields a sword, though it is unknown if she truly possessed any fencing skills; it is shown, later in the game, that she has skill with a bow.
