One possible fanfiction could be that Natsu and Mavis get married in a simple yet magical ceremony. Their friends from Fairy Tail are all present, and the guild hall is decorated with beautiful flowers. Natsu is nervous but excited, and Mavis looks stunning in her white dress. After the wedding, they embark on a journey together to explore new lands and discover hidden magic, all while growing closer as a married couple.
In this fanfiction, Natsu and Mavis' married future could be one where they build a small cottage near the guild. They have a peaceful life, with Natsu going on occasional guild missions while Mavis stays back to tend to their home and garden. Their days are filled with simple joys like cooking together and sharing stories by the fireplace at night.
Well, in many fanfictions, their relationship might start with Natsu being a bit in awe of Mavis as she is a very important figure in Fairy Tail's history. Natsu, being his brash self, might initially make mistakes around her but gradually learns from her wisdom. As time goes on, he could come to respect her even more deeply and they might form a bond where Mavis becomes like a guiding light for Natsu in his adventures and growth within the Fairy Tail guild.
In fanfiction, Natsu and Mavis could be like a mentor - mentee relationship. Mavis being the first master of Fairy Tail has a lot of knowledge and wisdom. Natsu could look up to her and she could guide him in his journey, much like how Makarov guided him in the main story.
One unique plot point could be Natsu having to learn magic in a completely different way under Mavis' tutelage. Instead of his usual hands - on, instinctive approach, he has to study theory and history. Another could be Mavis using Natsu to revive some long - lost traditions of the Fairy Tail guild. Maybe Natsu discovers a hidden power within himself that was dormant until Mavis guided him.
In some fanfictions, Natsu's dragon slayer magic and Mavis's Fairy Law could be combined in a unique way. For example, Natsu could use his fire to enhance the power of Mavis's Fairy Law, making it more destructive against their enemies.
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.
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.
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.
