One common theme is romance. At the ball, characters often get a chance to interact in a more formal and romantic setting, like a dance between two characters who have feelings for each other. Another theme is celebration. It's a time for the Fairy Tail guild to come together and celebrate a victory or just the fact that they are all alive and well.
Goku is often very popular. His immense power and simple - minded but kind - hearted nature make him a great character to incorporate into fanfiction. He can interact with the Fairy Tail characters in unique ways, like teaching them about his training methods.
There could be a fanfiction where the magic system of Fairy Tail is introduced to the Dragon Ball universe. Characters in Dragon Ball start to learn and use magic, which leads to all kinds of new adventures and power - ups. For example, Vegeta might struggle to master Fairy Tail's lightning - based magic while still maintaining his Saiyan pride.
One great Dragon Ball Z and Fairy Tail fanfiction is 'The Saiyan in Fairy Tail'. It combines the power systems of both universes really well. The main character, a Saiyan, ends up in the Fairy Tail world and has to adapt to their magic while also showing off his Saiyan abilities. It's a really exciting read.
One common theme is the power - up. In both 'Dragon Ball Xenoverse' and 'Fairy Tail', characters constantly strive to become stronger. So in fanfictions, you often see characters from both series finding new ways to increase their power, whether it's through training or some magical discovery.
Another popular trope is the fish - out - of - water story. When a character from Dragon Ball Z ends up in the Fairy Tail world or vice versa, they have to adjust to the new rules, culture, and magic or ki systems. It can lead to some really funny and heartwarming moments as they learn about the new world around them. For instance, Piccolo trying to understand the concept of guilds in the Fairy Tail universe.
A fanfiction could explore what would happen if Natsu from Fairy Tail learned the Kaioken technique from Goku in Dragon Ball Z. Maybe he uses it in a fight against a really strong opponent in the Fairy Tail world, but has trouble controlling the power at first, leading to some comical and intense situations.
One great story could be 'The Fusion of Worlds' which combines the elements of both Dragon Ball Z and Fairy Tail in an exciting way. It has cool battles and interesting character interactions.
You can try some popular fanfiction websites like FanFiction.net or Archive of Our Own (AO3). These platforms usually have a wide variety of fanfictions including those related to Dragon Ball Z and Fairy Tail.
Well, there's 'Fairy Tail Ball: The Magic Returns'. In this fanfiction, the ball is a reunion of sorts for the Fairy Tail members after a long and difficult adventure.
