Well, it could be about Nashi going on an adventure with Natsu. Maybe they discover a new magic together and have to fight some bad guys to protect their world.
The main characters are obviously Nashi and Natsu. Nashi is likely a new and interesting character, while Natsu is a well - known and powerful wizard from the original series.
Growth could also be a theme. Nashi would be growing up, learning about her powers (if she has any), and about the world around her. Natsu and Lucy would also be growing as parents, learning how to take care of a child, make decisions for the family, and balance their previous lives with their new roles as parents.
In the 'natsu and lucy baby nashi fanfiction', we can expect a lot of heartwarming scenes. Natsu and Lucy would surely have to adjust their lives. Nashi might inherit some of their powers or traits. There could be a story arc about Nashi growing up and wanting to follow in her parents' footsteps. The fanfiction might also show how their friends in the story react to the new addition to the family, and how they all contribute to Nashi's upbringing.
One common theme is self - discovery. When Natsu meets another version of himself, he often learns new things about his own capabilities and personality. Another theme is cooperation. Since they are essentially the same person, they have to learn to work together despite their initial differences.
One possibility could be that Natsu is on one of his adventures and stumbles upon a young Mavis in a magical forest. Their meeting could be filled with wonder as Natsu shows Mavis some of his cool fire magic tricks, and Mavis, in turn, shares some of her early knowledge of magic. It could be the start of an interesting friendship that defies time and space in the Fairy Tail universe.
Perhaps in the fanfiction, Natsu meets Erza in a completely new setting, like a parallel universe where the Fairy Tail guild doesn't exist yet. They start off as strangers but quickly realize they have similar goals. Erza might initially be a bit distrustful of Natsu's wild ways, but as they face challenges together, such as a group of bandits attacking a village, they learn to trust and rely on each other.
When thinking about who would be stronger in a 'Goku meets Natsu' fanfiction, we need to look at various factors. Goku's power levels keep increasing as he faces stronger opponents. He has the Kaio - ken technique and the super Saiyan transformations. Natsu, on the other hand, gets stronger as he eats more fire and overcomes difficult battles. His dragon force mode is one of his most powerful states. In a one - on - one battle, if it were in a wide - open space, Goku's long - range energy attacks might give him an edge. But if they were in a more enclosed, heat - based environment, Natsu could potentially use the surroundings to his advantage. Also, the strength in this fanfiction could be determined by the story's needs. If the writer wants to show the power of friendship and combined strength, they could make it so that neither is stronger alone, but together they are unstoppable.
In a 'Goku meets Natsu' fanfiction, they might start off by being confused about each other's powers. Goku could be intrigued by Natsu's fire - based magic, while Natsu would be amazed at Goku's super Saiyan strength. They could end up having a friendly sparring match to test each other's skills.
In a 'naruto meets natsu fanfiction', they might start off as rivals. Naruto, with his ninja skills and determination, and Natsu, with his dragon - slayer strength. But as they get to know each other better, they realize they have a lot in common. For example, they both have a strong sense of loyalty to their friends. So they end up becoming good friends and combining their powers to protect their respective worlds from threats that could endanger both.
