Yes, there are quite a few. You can start by looking on fanfiction.net or Archive of Our Own. Some works might explore their relationship in a very sweet and innocent way, building on the connection they had in the game.
One common theme is the idea of forbidden love. Since they come from different worlds, their relationship can be seen as something that goes against the norm in their respective societies. Another theme is the power of friendship turning into love, as they start off as allies and then feelings develop.
Adventure themes are also popular. Writers might create new quests or scenarios where Midna and Wolf Link have to face challenges together. This could involve battling new enemies or exploring uncharted lands in the Zelda universe.
Link and Midna's relationship would transform into a more domestic and committed one. They would share responsibilities like taking care of the baby at night, feeding, and teaching it. There would be new moments of tenderness between them as they watch their baby grow. Their relationship would no longer just be about their own connection but also about the future of their family and the legacy they want to leave for their child.
You can try some popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions on various topics, including Midna and Wolf Link. Just use their search function to look for relevant stories.
I really like the fanfic 'Link and Midna: A New Adventure'. In this, they embark on a journey to a far - off land that is filled with new and strange creatures. The author does an excellent job of portraying Link's silent determination and Midna's sassy yet caring nature. Also, 'Midna's Guidance' is a good one where Midna plays a crucial role in guiding Link through a series of dangerous trials.
One common theme is adventure. Since Link is known for his adventures in the Zelda games, it's often incorporated into the fanfics. Twili Midna might accompany Link on a new quest, facing various monsters and challenges together.
Friendship is also a big theme. Their relationship in the game can be seen as a strong friendship, and fanfics often develop this further. They might show how Midna and Wolf Link support each other through difficult times, like when facing powerful enemies.
You can start by looking on fanfiction.net. It has a large collection of fanfics, and you can easily search for Link x Midna ones. Another good place is Archive of Our Own (AO3). It has a well - organized tagging system, so you can find the specific type of Link and Midna fanfic you're interested in.
One possible plot could be that Link and Midna, after their adventures together, decide to settle down in a peaceful corner of Hyrule. Their baby could inherit unique powers from both of them. For example, the baby might have Link's courage and sword - fighting skills along with Midna's shadow - manipulation abilities. As the baby grows, they face challenges from those who fear their combined powers, and Link and Midna have to protect their family and teach their child to use their powers for good.
