It might not be a super common theme in all fandoms. In some more family - friendly or traditional fandoms, pregnancy themes for young characters like Edmund and Lucy might be quite rare as they are often seen as children in their original stories. However, in some more creative and alternative interpretations within the fandom, it could potentially exist, but it would likely be a very niche take.
She might start to blush furiously. Given her character, she is a bit shy when it comes to romantic matters. And then she might start to stammer out a response, not really sure what to say at first. As she composes herself, she could tell Natsu that she has feelings for him too but in a very gentle and sincere way.
Lucy might be heartbroken. After all, Team Natsu was like a family to her. She could initially go into a state of shock and disbelief. Maybe she would try to plead with the team to let her back in, explaining that whatever they thought she did was a misunderstanding.
Erza would probably be very protective. She would make sure Lucy has everything she needs and would be strict about her safety. Gray might be a bit awkward at first, but then he'd be supportive. Happy would be over the moon. He'd constantly be around Lucy, bringing her fish and trying to cheer her up. Wendy would be excited and would offer to use her healing magic to check on the baby's health regularly.
Their friends would likely be shocked at first. Happy for them, but also a bit worried. Erza, for example, would probably be very protective. She might start giving Lucy all sorts of advice on staying healthy and safe during the pregnancy. Gray might be a bit awkward around the whole situation at first, but would eventually warm up and offer his support in his own way, like helping Natsu with any odd jobs or tasks so he can focus on Lucy.
The Harry Potter fandom is great for oc fanfiction. There are so many aspects of the wizarding world to explore, like creating a new student at Hogwarts with unique magical abilities. Another good one is the Star Wars fandom. You can create original characters within the vast galaxy, perhaps a new Jedi or a smuggler in a far - off system. The Marvel Cinematic Universe is also a top choice. You could develop an original superhero or villain with powers related to the existing lore.
One of the top fandoms for fanfiction is the Doctor Who fandom. With its time - traveling and space - exploring premise, the possibilities are endless. You can create new adventures for the Doctor and his companions, or introduce new alien species. The Supernatural fandom is also very popular. There are so many different mythologies and creatures in the show that you can base your fanfiction on. And then there's the Percy Jackson fandom. It combines Greek mythology with modern - day settings. You can write about new quests for demigods, or explore the relationships between different characters from different cabins at Camp Half - Blood.
Some fans would be really excited. They might love the idea of seeing their favorite characters in a more mature and family - oriented situation. It could add a new dimension to the Natsu - Lucy relationship that they've always wanted to see.
Their friends would probably be really excited. Natsu might be a bit over - enthusiastic, constantly wanting to play with the baby and accidentally scaring it at first. Erza would be very helpful, giving advice on how to raise a strong and independent child. Happy would be curious and might offer to babysit in his own unique way.
