Well, a common theme is adventure. They might go on a quest to find a powerful magical item or to rescue a kidnapped friend. In these fanfictions, their different personalities add to the story. Brandish's more mysterious and sometimes aloof nature contrasts with Lucy's warm and friendly personality. Another theme is self - discovery. As they journey, they learn more about themselves and their place in the Fairy Tail world.
In some fan stories, Brandish's size - altering magic and Lucy's Celestial Spirit magic can be combined in combat. For example, Brandish could shrink an enemy while Lucy summons a Celestial Spirit to attack the now - smaller foe. Their abilities can also be used in a complementary way for non - combat situations, like Brandish using her magic to create a small space for Lucy to secretly summon a spirit for information - gathering.
The guild as a whole would likely mobilize. Erza would start formulating a strategic plan. She'd consider the strengths and weaknesses of Acnologia and figure out the best way to approach the situation. Gray would also be ready to fight, using his ice - make magic to support the rescue mission. They would all be united in their determination to get Lucy back safely.
One common theme is redemption. Given Brandish's complex backstory in Fairy Tail, many fanfictions focus on her finding a way to redeem herself or make up for her past actions.
One great 'Fairy Tail Brandish' fanfiction is 'Brandish's New Beginning'. It explores Brandish's character development after the main events in Fairy Tail. It has a great plot that dives deep into her past and how she's trying to find her place in the new world order of the Fairy Tail universe.
The plot is crucial. It could be something that ties in with the existing Fairy Tail lore but also takes it in a new direction. Maybe it involves Brandish in a time - travel adventure where she has to change the past to save the future of Fairy Tail. This kind of unique plot idea can make a fanfiction really stand out.
Midnight might use his illusions to make Lucy think she's lost her Celestial Keys. This would be a huge psychological blow to her. But then Lucy could remember the bond she has with her spirits and break through the illusions. It would be a battle of wills as much as magic.
The guild would likely be ecstatic. Gray would probably make some snarky comment about Natsu finally growing up, but deep down he'd be happy for his friend. Erza would be all for it and might start planning the wedding immediately, giving orders to everyone in the guild to help out.
Lucy could be extremely excited. After all, finding Igneel is like stumbling upon a legend come to life. She would likely be in awe of his presence. She might immediately think about how this discovery could benefit her friends in the Fairy Tail guild. She could also be very respectful and try to approach Igneel in a friendly manner.
