A sense of isolation can be a theme too. When Link is hurt, he may feel alone in his struggle, especially if he's far from civilization or help. This can lead to a more introspective look at his character as he battles not only his injuries but also his own feelings of loneliness and vulnerability in the vast world of Breath of the Wild.
One common theme is the struggle for survival. When Link is hurt, he has to fight not only his enemies but also his own weakened state. Another theme is the discovery of inner strength. Through his pain, Link often finds new abilities or a deeper resolve within himself.
In some fanfictions, Link could get hurt during a battle with a Lynel. The Lynel's powerful attacks might break Link's shield and leave him vulnerable. He could be injured badly on his arm, making it difficult for him to use his sword effectively. This would force him to rely more on his other skills, like his archery or his ability to dodge, while trying to find a way to defeat the Lynel and then tend to his wounds.
Often, the theme of redemption or reward is present. Link has gone through so much in his journey, and a kiss from Zelda can be seen as a sort of reward for his efforts. Also, themes related to the magic and mystery of Hyrule are common. The kiss might be tied to some magical event or discovery in the fanfiction. For example, it could unlock a new power or reveal a hidden secret about the land.
There is a fanfic titled 'Link's Injuries and Redemption'. This story not only focuses on Link getting hurt but also on how his friends and the environment around him play a role in his recovery. It details the challenges he faces due to his injuries and how he adapts to them, which makes for an interesting read.
One popular theme is adventure. Fanfics often take Zelda and Link on new and exciting adventures beyond what's in the original game. Another theme is the development of their relationship, whether it's friendship or romance. And the exploration of their individual powers and how they can combine them to face greater threats is also common.
One popular theme is the exploration of Link's character if she were female. How would her relationships with other characters like Zelda or the Champions change? Another theme is adventure - based, focusing on Female Link's journey across Hyrule in a different way compared to the male Link in the game.
One popular theme is the idea of Link as a protector in the context of his harem. Since he is a hero in the game, this often translates into him safeguarding the characters in his harem from various threats in the fanfic world.
Another theme might be the reactions of other characters to Link being hurt. They could show concern, or in some cases, it could lead to conflicts within the story. For example, some characters might blame others for Link's hurt state. Also, the theme of Link's vulnerability when hurt can be explored. It's a contrast to his usually strong and heroic image, and this can add depth to the story as he has to rely on others or find new strength within himself while injured.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3). There is a large community of Breath of the Wild fans there, and you can use the search function to look for stories specifically about Link getting hurt. Just type in relevant keywords like 'BotW Link hurt' and it should bring up relevant results.
A common theme is the exploration of the characters' backstories. Since the game doesn't fully explore every aspect of Link and Zelda's pasts, fanfics often fill in those gaps. Some might explore Link's time in the Shrine of Resurrection, or Zelda's struggles with her powers before the events of the game in more detail. This can add a lot of depth to the characters and their relationship.
A major theme is the exploration of the Breath of the Wild universe itself. The OCs often travel to different parts of Hyrule, discover new shrines, and encounter different races. This allows the authors to expand on the lore of the game. Power and its implications are also common. Some OCs have special powers, and the stories explore how they use or are tempted by that power. And of course, the theme of heroism. Even if they are not the main hero like Link, the OCs often find themselves in situations where they need to be heroic and help the people of Hyrule.
