One interesting story could be about the baby's unique powers emerging early and how Klaus and Hayley deal with protecting the baby from those who would misuse its powers. They might have to seek out allies in the supernatural community and face many challenges along the way.
The main characters are obviously Hayley, Klaus, and their baby. Hayley is a strong werewolf, Klaus is a powerful hybrid, and their baby is a significant part of the story as it combines their heritages.
Fanfiction.net is also a good place to search. There are many different categories and a wide range of stories. However, the search might be a bit trickier as you need to be more specific in your search terms. Try combinations like 'Klaus Hayley baby' to narrow down the results.
It could be the witches. They might see the baby as a threat to their power or a tool to gain more power. So they try to either take the baby or harm it.
In 'The Originals Hayley and Klaus Baby Fanfiction', a great plot could revolve around the baby's role in uniting different factions of the supernatural world. Since Hayley and Klaus come from different backgrounds, the baby could be seen as a symbol of hope for peace. However, there are those who oppose this unity and try to harm the baby. Hayley and Klaus then have to fight against these forces, and in the process, the baby starts to develop its own personality and ideas about how to bring about change in the world it was born into.
Well, perhaps in the fanfiction, the baby could be the key to uniting different factions in the 'The Originals' universe. The baby's existence could bring out a more tender side of Klaus, and Hayley could be the one who trains the baby in combat skills specific to their world. Also, there could be a prophecy about the baby that drives the whole story forward, like it will either save or destroy their world.
