Well, perhaps a unique plot point is that Mavis sends Natsu on a special quest that no one else in the guild has ever been on. This quest could be related to some ancient prophecy or a long - forgotten magic item. Also, there might be a plot point where Natsu has to face his inner demons with Mavis' help. Since Mavis has such deep knowledge of magic and the human heart, she could be the key to Natsu unlocking a new level of power or self - understanding.
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.
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.
One possible plot could be that there is some sort of misunderstanding or dark magic at play that causes Natsu and Mavis to fight. Natsu, being hot - headed, jumps into the fray without fully understanding the situation. Mavis, on the other hand, is trying to figure out a way to stop the fight without harming Natsu. As the battle progresses, they both start to realize that they are being manipulated and then team up to face the real enemy.
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.
Well, usually in such fanfictions, key plot points might include Natsu's adventures in high school. Maybe he's the alpha, so he could be dealing with challenges like protecting his friends from bullies. Another plot point could be his relationships, perhaps a budding romance with a fellow student. Also, there could be some sort of magic - related mystery or competition within the high school setting.
In a fight between Natsu and Mavis in a fanfiction, it's really hard to say who would win. Natsu is extremely powerful with his dragon slayer magic, being able to take on some really tough foes. However, Mavis is the first master of Fairy Tail and has a great deal of wisdom and powerful magic herself. It could really go either way depending on how the fanfiction writer wants to portray the battle.
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 idea could be Natsu going on a solo mission to a far - off land that has a different type of magic entirely. He has to learn to adapt and control this new magic to complete his task. Another could be Natsu training a new generation of Fairy Tail wizards, passing on his unique brand of magic and combat skills.
One interesting plot point could be Natsu getting into intense battles within the academy. Maybe he has to face a new kind of dark magic user that challenges his skills in ways he hasn't experienced before.
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.
In some fanfictions, Natsu as the 1st master of Fairy Tail might be depicted as a powerful and visionary leader. He could be shown as someone who laid the foundation for the guild's values of friendship and strength.
