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.
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.
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.
One great Fairy Tail Laxus fanfiction is 'Laxus' Redemption'. It shows his journey to overcome his past mistakes and become a better guild member. The story really delves into his character, exploring his relationships with other guild members in depth.
To develop Female Natsu's personality, you could show her trying to fit into the Fairy Tail guild in her own way. She might be a bit more sensitive about how others perceive her as a female version of Natsu. Laxus could be developed by showing his softer side more. He might start to open up to Female Natsu about his dreams and fears. Their personalities could also develop through their arguments. For instance, when they disagree on a mission strategy, it can lead to a deeper understanding of each other's perspectives.
A possible plot could involve a magical tournament. Female Natsu enters to prove herself, and Laxus also participates. They end up as reluctant allies at first. As the tournament progresses, they start to see each other in a new light. Their interactions during the battles, the post - fight banter, and the times they have to train together can all be opportunities for their relationship to grow. Maybe there's a sub - plot where an old enemy of Laxus tries to use Female Natsu against him, which further complicates their relationship.
A plot could involve Fem Natsu accidentally using her magic in a way that affects Laxus in an unexpected manner. For example, her fire magic could trigger some latent power in Laxus, and as they figure out what's going on, they become closer. This could also lead to some interesting training sessions between them as they try to control this newfound power connection.
