Well, one possible plot could be a love triangle situation. Erza and Mirajane both have feelings for Natsu, but Natsu is oblivious to their affections. They might compete in a friendly way at first, like trying to be the one to give Natsu the best meal or help him with his training. This could lead to some humorous moments as Natsu just doesn't pick up on their real intentions.
In the fanfiction, their relationships could develop slowly. Erza might start by being more protective of Natsu during battles. She has always been a strong fighter, and now she has an extra incentive to keep Natsu safe. Mirajane, on the other hand, could use her charm and her skills in the guild to make Natsu feel welcome and special. As time goes on, their feelings might become more obvious to other guild members, who could either encourage or tease them about it.
Growth is another theme. Writers like to show how Natsu, Erza and Mirajane develop their magic skills and as individuals over time. For example, Natsu might learn to control his power better, Erza becomes more strategic in battles, and Mirajane discovers new aspects of her magic.
One popular natsu erza mirajane fanfiction is 'The Trio's Adventure'. It focuses on their teamwork and friendship as they go on various quests. The characters are well - portrayed, staying true to their personalities from the original series.
Their personalities. Natsu is the hot - headed and impulsive one, always ready to jump into action. Erza is the strict and disciplined warrior, bringing order and strategy. Mirajane is the more laid - back but still very powerful one. Together, they create a great balance.
There's also 'Unlikely Allies' which is set during a war against a powerful dark guild. In this story, Natsu, Mirajane, and Erza form an unbreakable alliance, and their individual powers and personalities blend together to defeat the enemy. It has great action scenes and character development.
There might be a fanfiction where they participate in a guild - wide competition. Natsu would be all about winning, Erza would be determined to show her strength and uphold her honor, and Mirajane would be there with her own set of skills. In the story, they could form an unexpected alliance with other guild members and through teamwork, overcome challenges and rivals.
Well, in such a fanfiction, it could be a slow - burn kind of love. Natsu might be initially confused by his new - found feelings towards Erza. He could find himself constantly thinking about her, getting distracted during missions because of her. Erza, on the other hand, might be oblivious at first, being too focused on her duties. But as the story unfolds, she might start to see Natsu in a new light as well.
One possible fanfiction could be about Naruto visiting the Fairy Tail world and teaming up with Erza and Mirajane. They could go on a quest together to defeat a powerful dark wizard. Naruto's unique ninja skills would blend well with Erza's swordsmanship and Mirajane's takeover magic.
They could start by meeting in a strange, in - between world. Naruto is intrigued by Erza's armor and Mirajane's different forms. They soon realize they have a common goal, which is to find a way back to their own worlds. As they journey, they share stories of their past adventures, with Naruto talking about his battles in the Hidden Leaf Village and Erza and Mirajane sharing tales from Fairy Tail.
