Wendy could be a supporting character. She might look up to Natsu and Lisanna's relationship and learn about love and commitment from them. Carla could be there as well, with her usual snarky comments but also showing some support. And then there could be some minor characters from the guild who help with the decorations or entertainment during the wedding, adding to the overall charm of the story.
The main characters are Natsu and Lisanna. Natsu is a fire - dragon slayer, known for his energetic and somewhat reckless nature. He is always ready for a fight and has a strong sense of loyalty to his friends and guild. Lisanna is a sweet and kind - hearted character. She has a special connection with Natsu, and in this fanfiction, they are likely to be in a relationship or at least have a very strong bond as they are involved in the story of having a baby.
The main characters are clearly Natsu and Lisanna. Natsu is a well - known character with his fiery personality and powerful dragon - slayer magic. Lisanna is also important, she has her own set of skills and a unique relationship with Natsu.
One interesting plot could be their journey of getting to know each other on a deeper level before the marriage. Maybe they go on adventures together and face challenges that strengthen their bond. Another could be how their friends in the guild react to their relationship and upcoming marriage, with some being overly excited and others being a bit more cautious.
A plot point could be the couple's journey to find the perfect wedding venue. They might explore different magical places in the Fairy Tail world, like a floating castle or a hidden valley. Then there's the issue of the wedding dress. Lisanna could have a hard time choosing one, with all her friends giving different opinions. In the meantime, Natsu could be training to become a better husband, learning how to cook and do household chores with the help of some of the other guild members. And finally, the actual wedding day could be filled with unforeseen events, like a sudden storm that they have to magically overcome to have the perfect ceremony.
Gaara, Temari's brother, would surely be a significant supporting character. He would be involved in the decision - making regarding Temari's marriage. Hinata could also be a part of it, maybe as a friend to Naruto, offering her gentle support and understanding throughout Naruto's relationship journey with Temari.
Hermione would likely be a main supporting character. She would be there for Harry, giving him advice about his relationship with Cedric. She might also help them with any magical research or problems they encounter. Ron could also be a supporting character, perhaps at first being a bit confused or skeptical about Harry's relationship with Cedric, but eventually coming around and being supportive, like at their wedding.
Maybe an old enemy of Natsu's resurfaces. This enemy is jealous of Natsu's newfound happiness with Cana and tries to take Cana hostage to force Natsu to fight him. This would create a major conflict in the fanfiction.
Hermione could be a great supporting character. She would be the one to give Harry advice on his relationship with Gabrielle, using her logical mind. Ron might also be there, providing some comical relief with his typical Ron - like comments. Fleur, Gabrielle's sister, would obviously play a major role as well. She would be protective of Gabrielle at first but then come to accept Harry as a suitable partner.
Love is a very common theme. Since they have a pre - existing relationship in the original story, fanfictions often expand on their romantic feelings for each other. Another common theme is friendship. Their friendship is the foundation of their relationship, and many fanfictions explore how their friendship evolves into something more.
Gray could be a supporting character. He might be a bit jealous at first but then becomes a good friend and helps Natsu out when he gets into trouble. Erza could also be there. She would be like an older sister figure, giving advice to Levy on how to handle Natsu's sometimes reckless behavior. Happy, Natsu's Exceed friend, would definitely be around, providing some comic relief and also helping them out in various situations.
