One exciting moment could be when Natsu first unleashes his most powerful Fire Dragon Slayer attack against Laxus. The sheer power of the flames and the look of determination on Natsu's face would be thrilling. Another moment might be when Laxus counters with his Lightning Dragon Slayer magic, creating a spectacular display of light and energy as the two elements collide.
In my opinion, Natsu would have a good chance of winning. Natsu is known for his incredible determination and his ability to keep getting back up no matter how tough the fight. His Dragon Slayer magic gives him great power and his Fire Dragon's Roar can deal significant damage. Also, his experience in various battles has toughened him up. However, Laxus is no pushover either. He has his Lightning Dragon Slayer magic which is extremely powerful. But Natsu's never - say - die attitude might just tip the scales in his favor.
I've read one where Natsu and Female Laxus compete in a guild - wide tournament. At first, it's all about winning for themselves. But as the tournament goes on, they start to understand that they are both representing Fairy Tail. They begin to work together in a way, like when they face an opponent who is using dirty tricks. They combine their powers to defeat the cheater and in the end, they both gain a new respect for each other and for the guild.
In many Fairy Tail fanfictions, the battle between Natsu and Acnologia is often depicted as extremely epic. Natsu's fiery determination and his unique dragon - slayer magic make for an interesting contrast against Acnologia's overwhelming power. Some fanfictions might have Natsu discover new forms or powers in order to stand a chance against the fearsome Acnologia.
Some fanfictions to check out are 'The Dragon Slayers' Bond'. It really plays on their status as dragon slayers and how that common ground can bring them closer. There are a lot of sweet and tender moments in this one. 'Fire and Metal' is another one. It's set during a time when the guild is in danger, and Natsu and Gajeel have to work together closely. Their relationship blossoms as they fight side by side. 'Natsu, Gajeel and the Unspoken Feelings' is also a fan favorite, as it delves into the unsaid emotions between them that they're not quite sure how to handle.
One frequent theme is rivalry. They are both strong characters in Fairy Tail. So, in many fanfictions, there is a friendly rivalry between them. They might compete to see who can complete a mission faster or who is stronger in a sparring match. Also, the theme of self - discovery can be seen. As they interact, they learn more about themselves, like Natsu learning to be more strategic from Female Laxus and Female Laxus learning to be more spontaneous from Natsu.
One popular storyline could be Natsu and Laxus teaming up against a powerful dark guild. They have different fighting styles but learn to combine their strengths. Natsu's brute force and Laxus' lightning - based attacks could make for some epic battle scenes.
In some fanfictions, Natsu might be developed as more of a strategist than in the original series. He could learn from Laxus' more calculating approach to battles. Laxus, on the other hand, might be shown to be more open - hearted, influenced by Natsu's warmth and loyalty to the guild.
You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just type in 'Fairy Tail Natsu Gajeel yaoi' in the search bar, and a bunch of relevant stories should pop up.
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.
