A great fanfiction idea could be Hayley and Jackson's adventure in a different realm. Maybe they get transported to a magical world where they have to learn new powers and rules in order to get back home. This would show their growth as characters as they face challenges outside of their familiar supernatural world.
One interesting story could be about Hayley and Jackson's journey to build a new werewolf community together. It might involve their struggles against other supernatural forces that oppose their plans.
One possible storyline could be about how Klaus and Hayley deal with the impending arrival of their baby in a world full of supernatural threats. They might have to protect their unborn child from their many enemies.
Archive of Our Own (AO3) is also a great place. It has a well - organized tagging system. Just search for 'The Originals' and then look for tags related to Hayley and Jackson. You'll be able to find some really high - quality fanfictions there written by passionate fans. Some of the stories might be based on different interpretations of their relationship, from romantic to platonic and everything in between.
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.
A possible plot is that Hayley discovers some unique powers or prophecies related to her unborn baby during her pregnancy. This could lead her on a journey to find out more about the baby's destiny. Also, the pregnancy could be used as a way to bring different factions in the 'The Originals' world together, either in support or against her.
There might be a fanfiction where Jackson and Hayley are in a school setting. They could be paired up for a project and at first they don't get along. But as they work together, they start to understand each other better and develop a deep bond. It could show how their differences actually make them a great team.
Perhaps a plot where Hayley discovers something unique about her pregnancy that is related to the werewolf or vampire lore in the show. For example, her unborn child could have powers that start manifesting while still in the womb, and she has to figure out how to handle this new development.
One interesting crossover could be the combination of the demigod powers from Percy Jackson with the vampire and witch powers in The Originals. For example, a story could have a demigod team up with the Mikaelson family to fight a common enemy that threatens both the world of Greek mythology and the supernatural world of The Originals. This would bring a whole new dynamic as the demigod's abilities like controlling water or having super strength would interact with the vampires' speed and the witches' magic.
One great Jackson the Originals fanfiction could be a story where Jackson discovers a hidden power within himself. Maybe he can control a unique element that was previously unknown in the Originals' lore.
I really liked a fanfic called 'Love in the Bayou'. It shows Hayley and Klaus in a post - apocalyptic version of the bayou. Their love is a source of strength in this harsh new world, and it has some really intense and passionate moments between them that are very well - written.
