Well, you could write a fanfiction where the Flame God is reborn in a different form. For example, as a child with no memory of its former self. The Fairy Tail guild could take the child in and as the child grows, strange things start to happen. Powers of fire start to emerge, and they have to figure out who or what this child really is. It could lead to a great adventure filled with mystery and discovery.
A cool 'Fairy Tail Flame God Fanfiction' could involve a time - travel plot. A Fairy Tail member gets sent back in time and meets the Flame God in its prime. They form an unlikely alliance to stop an ancient evil that was once defeated by the Flame God. The Fairy Tail mage learns ancient fire magic from the Flame God during this time and brings that knowledge back to the present day to help the guild in a new and dangerous situation.
Natsu could be a great main character. Since he already has a strong connection to fire, his encounter with the Flame God could lead to him unlocking new levels of power. He could learn unique fire - based spells and techniques from the Flame God, which would be exciting to read about.

You could do a time - travel fanfiction. Have a character go back in time to when the Fairy Tail guild was first founded and see how they interact with the founders.
