There could also be an original character created for the fanfiction. For instance, a transfer student who has no connection to the original Fairy Tail members but quickly becomes friends with the next - generation characters.

They might have a unique magic that no one has seen before, which could lead to all sorts of adventures and challenges.

Another could be a new character who is related to one of the less - prominent members of the original Fairy Tail but has a special power that makes them important in the time - travel adventure. They all come together, driven by different motives like curiosity, a desire to save the future, or to understand their past better.
Gray and Juvia's offspring could also be central characters. They could have an interesting mix of ice - make magic and water magic. Maybe they struggle with controlling their powers at first, just like their parents did, but in different ways. And their relationships with the other next - generation characters could be complex, adding depth to the story.
The children of Natsu and Lucy would be great main characters. They could inherit their parents' powers and personalities. For instance, having the same determination as Natsu and the intelligence of Lucy.
One main character could be a transfer student who is actually from a family with a long history in the Fairy Tail guild. He brings with him a lot of knowledge and secrets about Fairy Tail. Alongside him, there could be a local student who is intrigued by this new student's stories and together they form a bond. They could be joined by other students who each have their own unique connection to the Fairy Tail concept, like a student who dreams of being a great wizard like Makarov.
The children of Natsu and Lucy would be great main characters. Their combined magic powers, with Natsu's fire and Lucy's celestial spirit magic, could create a really interesting character. They might inherit a special ability that comes from the combination of their parents' magic.
The children of Natsu and Lucy are often popular. Their combined powers and the legacy of their parents make them interesting characters. They might inherit Natsu's dragon - slayer magic and Lucy's celestial spirit magic, and their love stories could be full of action and magic.
Gray could also be a main character. He's cool and mysterious. Maybe he falls in love with a new girl in school who is really into art. She's always drawing in the schoolyard, and Gray is intrigued by her creativity. Another possible main character could be Erza. She's strong - willed and might be the one who helps her friends with their love problems while also having her own secret admirer in the school.
