Well, a plot could involve time - travel on Tenrou Island. A Fairy Tail member accidentally gets sent back in time to when the island was first created or a significant event in its past.

Or, there could be a story centered around a new threat that emerges from the depths of the island, something that the Fairy Tail members have never faced before and they have to figure out how to defeat it together.
One idea could be exploring the untold adventures of the Fairy Tail members on Tenrou Island before the main events. For example, a character could discover a hidden magic spell that has the potential to change the course of their battles later. Another could be about a friendship that forms between two characters during their exploration of a mysterious part of the island. And perhaps a story where a character has to face their inner demons while being isolated in a particular area of Tenrou Island.
Natsu is always an interesting character to focus on. His determination and his unique fire - based magic can lead to some exciting adventures on Tenrou Island.

Another plot could involve Bardock having to adapt to the magic - based society of Fairy Tail. He might initially struggle with understanding how magic works, but then discovers a way to combine his Saiyan power with the magic there.
