I'm not sure of specific titles off the top of my head. But if you search on AO3 as I mentioned before, look for ones with high ratings and lots of positive comments. Those are usually the better - quality fanfictions.
Some fanfictions that explore unique relationships between the characters in the 'champions' and 'link' context tend to be interesting. For example, ones that focus on how the champions interact with Link in different scenarios, like during battles or in more peaceful, character - building moments. You can also search for fanfictions that are part of a series, as they often have a more developed story arc.
There's also 'Shadows of the Hero' that explores the idea of Dark Link being not just an evil counterpart but having his own motives and emotions related to Link. It's really interesting as it gives a new perspective on their interactions. In this fanfiction, the author creates a vivid world where both characters have to face challenges that force them to reevaluate their relationship.
One great 'Champions Protect Harry Potter' fanfiction might be 'The Champions' Vow'. In this story, the champions from different houses come together in a very creative way to shield Harry from various threats at Hogwarts. It has some really interesting character interactions.
Fanfiction.net is also a great place to look. It has been around for a long time and has a vast amount of fan - created content. Just use the search bar and type in relevant keywords like 'champions' and 'link' to see if there are any interesting fanfictions available.
There's also 'Link and Midna: A Forbidden Love'. In this fanfiction, their love is shown as something that goes against the norms of their respective worlds. It delves deep into the emotions they might feel, like the fear of being judged and the strength of their love that overcomes all odds. It's a really engaging read if you like complex relationships.
There are quite a few great 'Link meets Linkle' fanfictions out there. For example, 'Linkle's Entrance into Link's World' is a story that details how Linkle enters Link's world and how he has to adjust to having her around. It shows the cultural differences between their two regions in the Zelda universe. Another one is 'Link and Linkle: United Forces' which is more action - packed. It has them combining their combat skills to take on a powerful dark force that threatens the land. And 'Linkle and Link: Unlikely Companions' is a fanfiction that explores how two very different characters, Link and Linkle, gradually become friends and partners.
One popular 'Link x Impa' fanfiction is 'The Bond of Hyrule'. It delves into their relationship as they face the challenges in Hyrule together. The story is filled with adventure and some sweet, budding romance moments between the two characters.
One great fanfiction could be 'A Bond Beyond Time'. It beautifully explores the relationship between Link and Mipha. It delves into their unspoken feelings and the connection they share. Another one is 'Mipha's Promise'. This fanfic focuses on Mipha's determination to protect Link and how their bond evolves through different challenges. There's also 'Link and Mipha: The Lost Memories' which is about rediscovering their past relationship through a series of adventures.
Romance - centered fanfictions might also be appealing. Link and Ilia have a relationship, and a fanfiction that delves deeper into their romantic feelings, such as a story where they overcome obstacles in their relationship. Maybe a situation where Link has to choose between his duty as a hero and his love for Ilia, and how they work through it together could be a great fanfiction for them.
The 'Spirit of the Forest' fanfiction is quite good. It delves deep into the lore of a fictional forest spirit and the adventures of the characters who encounter it. It has a great plot with interesting character development.
Well, 'Twilight Encounters of Link and Dark Link' is quite interesting too. It takes place in a sort of twilight - like realm where the boundaries between the two are blurred. The author does a great job of portraying their relationship in a very nuanced way, making it a must - read for fans of this type of fanfiction.
