One common theme is adventure. Since Link is often associated with going on quests in the Zelda games, in harem fanfiction, his harem members might accompany him on these adventures. Another theme is the development of relationships. It shows how Link interacts with each member of the harem, from initial meetings to deeper emotional connections.
Well, a Breath of the Wild Link x Harem fanfic can be both exciting and challenging to write. On one hand, there are so many interesting characters in the game that could potentially be part of Link's harem. On the other hand, the writer has to manage all these relationships and make them believable. It's not just about having a bunch of characters together, but about creating a coherent story where Link's character develops through these relationships and the interactions with his harem members are meaningful.
To develop the harem characters effectively, give each of them a unique backstory related to Link. For example, one could have a past encounter with Link that changed her life. Another way is to give them distinct personalities. One could be shy and reserved, while another is bold and outspoken. This creates contrast and makes them more interesting.
Another option is to check out some dedicated Zelda fanfiction communities. These might have a more focused collection of stories, and members often recommend good reads. You can join in on discussions and ask for Link x Harem fanfiction recommendations specifically. They may point you to some hidden gems that aren't as easily found on the larger fanfiction platforms.
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.
Well, a popular trope is the 'love triangle' within the harem. Even though it's a harem, there might be a more intense connection between Link and two of the harem members, creating drama. Also, the 'shared adventure' trope. Link goes on adventures and the harem members are part of those adventures, strengthening their bonds. And there's the 'rivalry within the harem' where members might compete for Link's attention in different ways.
Fanfiction.net is also a good place. There are a lot of different categories and tags you can use to narrow down your search for link harem fanfiction. However, the interface might be a bit more dated compared to AO3.
One common theme is the exploration of opposites. Female Link often represents light and goodness, while Dark Link is the opposite. Their relationship in these fanfictions usually revolves around how they interact given these differences.
There's also 'Link in the Harem of Hyrule'. In this fanfiction, it delves into how Link manages his relationships with different characters in a harem - like setting. The author does a great job of weaving in elements from the Zelda universe.

I'm not sure there are a lot of existing fanfictions specifically on this pairing with a pregnancy theme. However, it could make for an interesting story. Link is often portrayed as a heroic figure, and Tetra is a strong female character. In a fanfiction, their relationship could develop in unique ways leading to a pregnancy, perhaps in a post - victory scenario where they start to build a new life together.
