Tetra

Tetra is a recurring character in. Orphaned at a young age, the young pirate follows her deceased mother's footsteps by becoming the captain of a ship with her crew of pirates, who all respect her deeply despite that she is much younger than them. Even though Tetra has a tendency to act tomboyish, take challenges head on, and even act bossy and cold-hearted sometimes, she actually has a kind and caring personality.

Leader of the Pirates
When Link first meets Tetra, she is being kidnapped by the Helmaroc King. The monster bird is distracted by Tetra's crew and she is dropped into the Fairy Woods. Link comes to her rescue, but because of this distraction, his sister Aryll, mistaken for Tetra, is kidnapped instead.

After much persuasion, Tetra allows Link to accompany her and her crew in their ship in a bid to save his sister from the Forsaken Fortress. At first, Tetra does not take a liking to Link, mocking him and showing distrust towards him due to his tendency to act without thinking things through. After finally reaching the Forsaken Fortress, Tetra and her pirates launch Link into the fortress by catapulting him in a barrel. Before she launches him off, however, she slips in the Pirate's Charm in his pocket, which Tetra uses to communicate with the young hero and drop hints occasionally. Link, however, ultimately fails to rescue his sister and Tetra and him go their separate ways.

The pirate leader and the young hero meet again briefly in Windfall Island when they are both trying to reach Jabun's hidden cave behind Outset Island. When Gonzo suggests that they stay at Windfall for the night, Tetra quickly dismisses that option, saying that they have to set sail to Outset immediately since it could meet the same fate as Greatfish Isle. Mako points out Tetra's caring personality as he mentions that it sounds like she is more worried about the island than the treasure, to which Tetra calls ridiculous and reaffirms her desire for the treasure. However, Tetra soon after catches Link spying on the pirates in the Bomb Shop, and decides to give Link a head start to reach Jabun.

Tetra catches up with Link in the Forsaken Fortress again as he tries to save his sister. The young pirate, upon meeting with Link, claims that Link never thinks before he acts since her crew had to distract the Helmaroc King for him before the bird would capture him again. She is shocked to see that he has the Master Sword in his possession, and even thinks that Link might be the Hero of Time or a descendant of him; however, she quickly shrugs off the thought seeing that it would be impossible. She promises Link that she will take Aryll and take her back to Outset safely, mentioning that she usually expects a reward for something like that, but offers to do it for free.

Princess of Hyrule
Later on, after defeating the Helmaroc King, when Link is nearing defeat at the hand of Ganondorf, Tetra runs into the room to distract him. However, she is easily defeated as well. While in Ganondorf's grasp, his Triforce of Power resonates, leading him to believe that he has finally found Princess Zelda. Tetra denies this, claiming that she does not know anyone named Zelda. After another distraction by the Rito and the Great Valoo, Link and the unconscious Tetra get away safely from Ganondorf and head to the sunken Hyrule Castle, where they meet King Daphnes Nohansen Hyrule.

The king asks that Tetra approach him, where he takes her necklace. The necklace, which was given by her mother and instructed Tetra to guard it with her life, is actually a piece of the Triforce of Wisdom. The King of Hyrule uses the other piece of the Triforce of Wisdom to reveal Tetra's true identity: Princess Zelda. Tetra is in shock, and apologizes to Link for everything that has happened to him and his sister. The King then tells the Princess that she would be safer hiding in the castle basement from Ganondorf's grasp while he and Link return to the surface to search for the Triforce of Courage.

When Link returns to Hyrule Castle with the Triforce of Courage in his possession, he sees that Zelda was captured by Ganondorf and taken to Ganon's Tower, and the young hero quickly seeks to save her. Once Link defeats Puppet Ganon and climbs up to where Ganondorf and Princess Zelda are located, he finds Zelda knocked unconscious, and although the young hero tries to best Ganondorf, he swiftly takes Link and Zelda's Triforce pieces.

After King Daphnes Nohansen Hyrule wishes for Hyrule to be flooded once more, Zelda wakes up and apologizes to Link for having overslept, where she urges Link to defeat Ganondorf once and for all and return to their ocean from the world above. During Link's battle with Ganondorf, Zelda wields the young hero's Bow and Light Arrows to cover Link and allow him to attack as best as he can. During the battle, however, Ganondorf hovers over to Zelda and knocks her unconscious again, but after a while, she wakes up again. She aims a Light Arrow at the young hero's Mirror Shield, which bounces off to Ganondorf and allows Link to deal the final blow.

Princess Zelda suggests to King Daphnes Nohansen Hyrule to join Link and her in their search for the new land that will be the next Hyrule. After Link and Zelda resurface to the Great Sea, Tetra appears again in her pirate clothes, having lost her royal persona as her pirate crew greets the two of them aboard their ship. Tetra is last seen during the ending credits where she, her pirate crew, and Link set sail from Outset Island in search of new lands.

Four Swords Adventures
In the Japanese and Korean versions of, Tetra appears in the Navi Trackers mode. She sends the Links out to solve puzzles and locate several stamps held by her pirate crew. In this mode, Tetra speaks in full voice acting. She vocally speaks to the Links, calling them by name to signify who she is speaking to, in order to provide instructions and updates on the current game, including who is in the lead and where the Links need to go.

Tetra, along with the entirety of the Navi Trackers mode, was removed from international versions, likely due to the voice acting being difficult to implement.

During the beginning of the game, she and Link happen upon a Ghost Ship, which they investigate. Tetra is separated from the others and is kidnapped, forcing Link to try and rescue her.

Once Link defeats the Cubus Sisters on the Ghost Ship, Link finds Tetra turned to stone. Once Link defeats Bellum's first stage, Tetra turns back to normal. After Link defeats Bellum, he and Tetra awaken on the Ghost Ship, only ten minutes after the prologue according to the pirates. Tetra's crew tries to convince her that it was just a dream, but Link finds the in his pocket, and the S.S. Linebeck is seen sailing in the distance.

Spirit Tracks
Though Tetra does not appear in, she makes an appearance in a stained glass window in the Throne Room of Hyrule Castle. Some of her history following Phantom Hourglass is detailed by her great-great granddaughter, the reigning Princess Zelda, and the Lokomo sage Anjean. Anjean states that she first met the pirate captain of royal lineage long ago, when she first arrived on the shores of the land that would become the new land of Hyrule. Anjean entrusted Tetra with the Spirit Flute, on the promise that she and her descendants would use the flute to protect the land for good. Tetra carried on a close friendship with Anjean for many long years and passed the Spirit Flute down through her descendants. Upon meeting the reigning Princess Zelda in Spirit Tracks, Anjean notes the remarkable similarities in personality between the princess and her ancestor, who was known for her feisty nature and courage. In the final battle with Malladus, Princess Zelda prays to Tetra for strength to recover her body and defeat the Demon King.

Tetra plays an important role in the Wind Waker series of Scenarios in Hyrule Warriors Legends' Legend Mode. Tetra is the first to bear witness to the dimensional rift in her era, seeing Windfall Island the Forsaken Fortress fused together. She rushes headfirst into battle to fight off against the invading monsters, but is soon then aided by the Link from the present era. Teaming up with the hero, they were able to stave off the attack, but Tetra is then kidnapped by the Helmaroc King and dropped off at the Gerudo Desert. While the monster was still roosting, she attempts to make her escape, but is soon pursued once more. At that time, Link and Lana (who was investigating the whereabouts of her other half, Cia) come to her aid. Combining their strength, they were able to fell the Helmaroc King.

Right after, they are approached by King Daphnes himself. Lana theorizes that Cia's disappearance is linked to this new threat and forms an alliance to save her from the darkness. After a long, harrowing fight, they were able to rescue the weakened Cia from the darkness, albeit weakened. She then informs them that the source of the threat was none other than Phantom Ganon, who had stolen her dark magic. If separated for too long, the sorceress would die. Tetra and the others vowed to save their land and Cia by heading to the fused Wind and Earth Temples where he laid hidden. The group perseveres and finally confronts the phantom itself. With their combined might, they shot forth a bolt of light that weakened the monster. With their teamwork, they finally slew the apparition, relinquishing Cia's magic along with the Triforce of Power. With everything set right, Tetra and the king fade back into their world, waving good-bye to Link and the sorceresses.
