A really interesting concept would be to delve into the backstories of the new generation. What if some of them had secrets about their heritage that even they didn't know? Maybe one of them is related to a powerful but long - gone wizard from the past. This could add a whole new layer of mystery and drama to the fanfiction, as they uncover their true identities while also dealing with the typical Fairy Tail chaos.
Perhaps they travel back in time to meet their parents or the original Fairy Tail members when they were young. This could lead to some really heartwarming or comical moments. They could learn new magic techniques from the past members and bring those skills back to their own time to use against a new threat.
You could write about how the next generation faces a new, more powerful dark guild. They might have to learn from the past adventures of their parents while also coming up with their own strategies. This could involve training arcs where they master their magic in unique ways, different from their predecessors. And perhaps they'll find hidden powers within themselves that were dormant until this new threat emerged.
First, think about the characters you want to include. Decide which of the original Fairy Tail members' children or mentees will be your main characters. Then, come up with a basic plot idea, like a new mission or a mystery to solve. After that, start writing an introduction that sets the scene and gives a bit of background on your new characters.
One idea could be that the next - gen characters discover a long - lost magic that was sealed away by the first generation. This new magic could bring both great power and great danger.
The children of the main characters from the original Fairy Tail series would be obvious choices. For example, Natsu and Lucy's child could be a main character. They would have their own unique magic abilities, a combination of their parents' powers perhaps. Their journey through time would be driven by a sense of curiosity about their parents' pasts and a need to protect the future of Fairy Tail.
One idea could be that the next generation discovers a hidden spell from the old Fairy Tail days that has the power to either save or endanger the guild. Another could be a tournament where the newbies team up with old - school Fairy Tail members to compete against other guilds.
One idea could be the children of Natsu and Lucy having to deal with a new dark guild that has emerged. They inherit their parents' powers but also have to figure out how to use them in new ways to combat this threat.
One idea could be focusing on the children of Naruto and Hinata. Maybe their son has to deal with a new and powerful enemy that is targeting the Uzumaki clan. He could discover some long - lost jutsu that his father didn't know about and use it to defeat the foe.
Maybe an OC who is from a foreign land outside of the main ninja villages. They come to the Hidden Leaf Village with a different set of skills and a different view on the ninja way. Their interactions with the established Next Gen characters, like Boruto and his friends, could create some really interesting storylines. For example, they might introduce new jutsu or training methods that are unheard of in the village.
One idea could be Wendy going on a solo adventure to a far - off land in the Fairy Tail universe to discover a new type of magic. She could meet unique characters and face challenges that test her skills and growth as a mage.
