What is the relationship between Link and Zelda?

Context: Link is a fictional character and the protagonist of Nintendo's video game franchise The Legend of Zelda. He was created by Japanese video game designer Shigeru Miyamoto. Link was introduced as the hero of the original 1986 The Legend of Zelda video game and has appeared in a total of 19 entries in the series, as well as a number of spin-offs. Common elements in the series include Link travelling through Hyrule whilst exploring dungeons, battling creatures and solving puzzles until he eventually defeats the series' primary antagonist, Ganon, and saves Princess Zelda.

Throughout The Legend of Zelda series, Link has made multiple appearances in a variety of incarnations. He has been rendered in both 2D and 3D form and has been traditionally depicted in his signature green cap and tunic carrying a sword and shield. Over the course of the series, he appears as a child or young adult of the Hylian race, which originates from the fictional kingdom of Hyrule. Within Zelda lore, Link is the soul of a legendary hero that throughout history is reincarnated within a seemingly ordinary boy or man when the need arises for a new warrior to defeat the forces of evil. To defeat Ganon, Link usually obtains the mystical Master Sword or a similar legendary weapon, which is obtained after completing various trials. Over the course of his journey, he also acquires other magical items, including musical instruments and other weaponry.

In addition to the main series, Link has appeared in other Nintendo media, including merchandise, comics and manga, and an animated television series. He is a prominent character in various spin-off games, including Hyrule Warriors, Cadence of Hyrule and Hyrule Warriors: Age of Calamity. He has appeared in entries of several other game franchises, including the Super Smash Bros. series, SoulCalibur II and Mario Kart 8, and has also been referenced in other games, such as The Elder Scrolls V: Skyrim.

Alongside fellow Nintendo character Mario, Link is one of the most recognisable characters in the video game industry. He has been instrumental in the establishment of the role-playing video game genre as the protagonist of the series, which has influenced numerous other video games with its concepts of open world and nonlinear gameplay. According to Guinness World Records, Link is the most critically acclaimed videogame playable character and the most ubiquitous action-adventure video game character, surpassing Mario. He has been recognised by the Guinness World Records Gamer's Edition as the second best video game character of all time after Mario. Critics have also named him as one of the most influential video game characters of all time and one of Shigeru Miyamoto's most famous creations.

Link is a brave, skilled warrior and the hero of The Legend of Zelda series. Over the course of the series, he has appeared in a variety of ages and forms, ranging from child to young adult, and in Twilight Princess, also appears in the form of a wolf. He displays the characteristic traits of the Hylian race, being of human form with elfin features, including pointed ears. Since the original 1986 The Legend of Zelda video game, he has been repeatedly depicted wearing his characteristic green cap and tunic. He has also appeared wearing other outfits, including a blue lobster shirt in The Wind Waker and his blue Champion's Tunic in Breath of the Wild. Link is described in the original game's instruction manual as a "young lad" and a traveller and in later games, such as Breath of the Wild, as a knight of Hyrule who is sworn to protect the kingdom and Princess Zelda. During gameplay, he carries a sword and a shield, but has also wielded a variety of other weapons, including bows, spears and axes.

Link's signature weapon is the Master Sword, a powerful magic sword that has the ability to repel evil. He is also often depicted holding the Hylian Shield. These two components have become integral aspects of the character's identity. Each game in the series follows a similar story arc in which Link must take a journey that eventually leads him to recover the Master Sword, which makes him stronger in gameplay and enables him to defeat the series' main antagonist, Ganon.

Throughout each game, Link is able to obtain various items during his adventures, which the player can then use in gameplay. Many of these objects possess magical properties that bestow specific abilities on Link, such as a magic cape that makes Link invisible when he wears it, or potions that replenish his health. Others have various practical purposes, such as the hookshot, which enables Link to pull items towards him, and bombs for detonation. Link has used various musical instruments on his travels, most notably, the Ocarina of Time, which when played is used for teleportation. In Breath of the Wild, Link's key tool is the Sheikah Slate, a handheld tablet featuring various runes that enable him to manipulate the game world.

In Zelda lore, Link is the reincarnated soul of a hero, chosen by the goddess Hylia to protect the kingdom of Hyrule from Ganon and save Princess Zelda whenever the need arises. As the goddess' chosen hero, he is also the bearer of the Triforce of Courage, one of the three components that combine to form the Triforce, a sacred artefact and symbol of power. In several Zelda games, Link's main objective is to recover the fragments of the Triforce in order to defeat Ganon. Link's character is always depicted as a fearless hero and a "symbol of courage" who is willing to protect Hyrule for the sake of others.

Relationships
Link's relationships with the other main characters has been a defining aspect of the series. Within the fictional lore, Ganon, Zelda and Link represent three pieces of the Triforce, with Ganon representing Power, Zelda representing Wisdom and Link representing Courage. This trinity transcends the fictional timeline and dictates that the three characters are destined to be forever reincarnated in an endless battle for good and evil. Link's battle with Ganon established a fictional chronology that spans across the entire series and branches into three separate timelines. The three timelines originate at the end of Ocarina of Time when the timeline splits according to whether Link successfully defeats Ganon or fails to stop him. The official fictional chronology was revealed in Hyrule Historia, with Skyward Sword presented as the first game in the timeline. Skyward Sword establishes that the three main characters are destined to be connected in an endless cycle after the antagonist Demise curses Link and Zelda.

Link's relationship with Zelda has been a core aspect of the series but has also been the subject of speculation. Throughout the games, the storylines have suggested the possibility of a romantic relationship between the two, but this has remained ambiguous. With each game release, the nature of their relationship has varied and Link has also been presented with other possible love interests. A romantic relationship between Link and Zelda is particularly evident in Skyward Sword and was also emphasised in an official "romance trailer" for the game. Aonuma commented on this relationship in an interview with Game Informer: "As far as the love story goes, it wasn't that we wanted to create a romance between Link and Zelda as much as we wanted the player to feel like this is a person who's very important to me, who I need to find. We used that hint of a romance between the two to tug at the heartstrings". In Breath of the Wild, the relationship between Link and Zelda is more complex and follows a story arc that begins with resentment and ends in a close bond with each willing to give their life for the other.

Answer: Link's relationship with Zelda has been developing as the story flows. In lore, Link, Zelda, and Ganon (the evil) represent three pieces Triforce, corresponding to Courage, Wisdom, and Power, respectively. The three are destined connected in an endless cycle.
People speculate that Link and Zelda are in a possible romantic relationship. Although not told by the story, there is evidence in and out of the games that this relationship is true. The game producer, Eiji Aonuma, once said otherwise that it was not their intention to create a romantic relationship between the two, but to the most important person for each other.
