Typically, you can expect a romantic or perhaps a very emotional scene. It might explore the relationship between Natsu and Erza in a new light, showing how they feel about each other.
Yes, there are likely some fanfictions out there with such a plot. You can try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net.
Well, the other characters' reactions would vary. For example, Mirajane would have a big smile on her face. She's always interested in the love lives of her guildmates. She might start planning a romantic scenario for Natsu and Erza right away. Elfman would be a bit uncomfortable, muttering something about men not being so clumsy. Lisanna would be excited and encourage Erza to give Natsu a chance. Cana would bet on whether they will end up together or not, and Gildarts might give Natsu some fatherly advice on how to handle the situation with Erza.
Sure. In such a fanfiction, it might occur during a celebration. Everyone is having a great time and Natsu, who is excited as always, jumps around and accidentally bumps into Erza. Their lips meet for a brief moment. Immediately, Natsu realizes what he has done and freezes. Erza is stunned. After a moment of silence, Erza might give Natsu a stern look, but deep down she's a bit flustered. Natsu then spends the rest of the day trying to avoid Erza out of embarrassment, while Erza is left thinking about that unexpected kiss.
In many fanfictions, Natsu and Erza often have a complex relationship. Natsu is usually depicted as a bold and passionate character, while Erza is strong - willed. Their relationship might start from comradeship within the guild. Some fanfictions may explore how they gradually develop deeper feelings for each other, like through shared adventures and facing challenges together. This can lead to a mutual understanding and respect that could potentially turn into a romantic relationship.
Happy, Natsu's flying cat companion, is a must - include. Happy could be really excited about the new baby and constantly bring little things he thinks the baby would like, like small fish or soft feathers. Wendy would also be a great character to involve. As a healer, she could be checking on Erza and the baby's health regularly, and she might also share her own knowledge of magic that could be related to the pregnancy in some way.
It could also show the complexity of their relationship. Maybe Erza's actions are out of her own insecurities or fears, and Natsu getting hurt is a consequence of her not being able to handle those emotions properly. This would mean that their relationship is not just about friendship or comradeship, but also about understanding each other's inner turmoil.
Another theme is growth. Fanfictions may show how Natsu and Erza grow as individuals and as a pair. For example, they could face challenges that force them to become stronger both physically and emotionally, and their relationship evolves as they overcome these obstacles.
In Natsu x Erza fanfic, their relationship can be full of adventure - based camaraderie. Natsu is often depicted as the impulsive and powerful mage, while Erza is the strong - willed and disciplined one. They might team up frequently, with Natsu's spontaneity contrasting Erza's calculated moves. This can lead to interesting character dynamics, where they both learn from each other and grow together in their fictional adventures.
There's also a possibility that it causes a rift in the guild. Other members might take sides. Some might side with Erza, believing she had a good reason, while others might side with Natsu, feeling that Erza was too harsh. This could create a lot of tension within the Fairy Tail guild and further complicate the relationship between Erza and Natsu.
One possible plot could be that they discover the pregnancy and then face challenges together. Maybe they have to deal with the reactions of their friends in the guild, some being happy and supportive while others might be worried about how it will affect their adventuring lives.
