They could be on a quest to find a magical artifact that has been lost. Along the way, they face various challenges and obstacles. Belle's intelligence and Rumpelstiltskin's magic skills are both needed to overcome these difficulties, and through this journey, they develop mutual respect and a deep bond of comradeship.
They could form an unlikely alliance to defeat a greater evil in the fairy - tale world. For example, a powerful dark sorcerer is threatening their kingdoms, and they have to put aside their differences and work together using their unique skills and knowledge.
One idea is that Belle's pregnancy causes her to gain some new magical abilities. This makes Rumpelstiltskin both proud and a bit jealous. They then have to figure out how to control and use these new powers while also preparing for the baby. For example, Belle might be able to sense threats from afar now, and they use this to avoid danger.
One idea could be a story where Belle discovers a hidden side of Rumpelstiltskin's past that changes her view of him. Maybe she finds out about a lost love he had before he became the Dark One, and this new knowledge makes her more empathetic towards him.
Another idea is that Eric and Ariel start a school where mermaids and humans can learn about each other's cultures. It could be full of comical misunderstandings at first, but as they work through these issues, their bond as a couple strengthens. There could be sub - plots about students from both sides falling in love as well, mirroring Eric and Ariel's relationship.
One idea could be Drake and Josh starting a new business together. They could face various challenges like finding the right location, dealing with difficult customers, and coming up with creative marketing strategies. This would show their friendship and how they work together to overcome obstacles.
One possible scenario could be that Rumpelstiltskin, despite his dark past, becomes extremely protective of Belle during her pregnancy. He might use his magic to ensure her comfort and safety, like creating a special charm to keep away any potential harm. He could also be seen gathering all the rare and precious items from his collection to make a perfect nursery for their unborn child.
You could explore fanfiction about Erza's adventures in new quests. For example, she could be on a mission to save a lost magical artifact and along the way she meets new characters and forms new alliances. This would focus on her strength and her role as a powerful mage.
One idea could be that Darkseid tries to corrupt Supergirl in a non - physical, more ideological way. He might tempt her with power and a different view of the universe. For example, he shows her how the current state of the universe has flaws and that his way could 'fix' it. Supergirl, of course, has to resist this temptation using her strong moral compass.
A possible plot could involve a parallel dimension. Percy and Artemis get pulled into a parallel dimension where the laws of nature are different. In this dimension, their powers interact in an unforeseen way and Artemis becomes pregnant. They must find a way to return to their own dimension while also dealing with the consequences of this new situation. They could encounter strange creatures and face unique challenges that test their abilities and their relationship.
The plot could involve Belle being in a much darker situation than in the original story. Maybe she makes a deal with Rumpelstiltskin that has unforeseen tragic consequences. For example, she might try to save her village but end up sacrificing her own freedom in a more extreme way. Rumpelstiltskin, being his devious self, could twist the deal so that Belle finds herself trapped in a never - ending cycle of despair and regret.
Another theme is the power of true love. In some fanfictions, it's Belle's love that has the power to break Rumpelstiltskin's curses or dark spells. It shows how a deep and pure love can have a strong impact on even the most powerful and dark - hearted characters.
