Tetra

Tetra, also known as Dazel in some languages, is a recurring character in the Legend of Zelda series. Tetra is a tan, blonde pirate girl and successor to her mother's gang of pirates. A fearless and even merciless pirate, she seems, at first glance, cold and to care only about herself and treasure, but in reality is quite kind and caring for others.

The Legend of Zelda: The Wind Waker
At the very beginning of the game, Link rescues Tetra in the Forest of Fairies on Outset Island, after she was dropped there by the Helmaroc King. However, shortly thereafter, Link's sister Aryll is kidnapped by the same bird. While she initially shows distrust for Link, she allows him to travel with her on their pirate ship, so Link can reach the Forsaken Fortress and rescue Aryll. Throughout the adventure she warms up to him and in return her pirates help him twice.

Tetra is revealed to be a descendant of Princess Zelda in the line of the ancient Hyrulean Royal Family when the King, Daphnes Nohansen Hyrule, gives her the rest of the Triforce of Wisdom. In the final battle, she helps Link defeat Ganondorf by shooting Light Arrows in various manners. At one point in the battle, Ganondorf's slaps her and knocks her out for around two minutes. When she regains consciousness, she again helps Link defeat Ganondorf by firing Light Arrows at Link's shield to hit Ganondorf. Shortly after, she and Link embark to find a new land that will be the next Hyrule when ancient Hyrule is flooded.

The Legend of Zelda: Phantom Hourglass
Early on in Phantom Hourglass, Tetra boards a mystical Ghost Ship. Suddenly, the Ghost Ship disappears with her still aboard it. Eventually, Link manages to find the Ghost Ship; however, he finds that she has been turned to stone by the monster Bellum. Link keeps her in the hold of the S.S. Linebeck. When Link eventually manages to restore her, she is kidnapped by Bellum, who possesses the Ghost Ship. Link chases after the Ghost Ship and eventually manages to defeat Bellum. After peace has been restored, Link, Tetra and the Pirates sail together back to the Great Sea from the World of the Ocean King.

The Legend of Zelda: Spirit Tracks
While Tetra does not make a physical appearance, a stained-glass window depicting her can be seen in Hyrule Castle's throne room. Also, when Zelda's spirit tries to get back in her physical body, she asks for Tetra's blessing.
