To end a Fairy Tail fanfiction, it could be interesting to look at the future. After the main events of the story are over, write a short epilogue that shows where the characters are headed. Are they going on new adventures? Have they retired from the guild? You can also end it on a bittersweet note. For instance, a character may have to leave the guild to pursue a personal dream, but they leave with the love and support of their friends, showing that change can be both sad and positive.
One popular 'End Join Fairy Tail' fanfiction might be 'The New Adventure'. It often features new characters joining the Fairy Tail guild and going on unique quests. Another could be 'End Join: The Power Within' which focuses on the development of the joined characters' powers within the Fairy Tail universe.
Sure, in the 'Fairy Tail' universe, the concept of Natsu being END is quite fascinating. Fanfiction writers often take this idea and run with it. They might create stories where Natsu discovers his true nature as END more gradually, or they could write about how the other guild members react when they find out. It can also lead to stories that explore the origin of Natsu as END and how it ties into the overall lore of the 'Fairy Tail' world.
First, you need to know the Fairy Tail universe well. Read the original manga or watch the anime. Then, think about the characters you want to have join at the end. Create a backstory for them that fits into the Fairy Tail world. For example, if it's a character from a different land, explain how they heard about Fairy Tail and what made them want to join.
There are some great ones. Some focus on Natsu's growth and how he overcomes final challenges at the end of the Fairy Tail story. Others might explore his relationships in a more in - depth way as the story comes to a close. It really depends on what kind of story you're interested in. If you like action - packed endings, look for ones where Natsu is using his full power to save the day. If you prefer more character - driven stories, there are those that deal with his emotions and bonds with other characters at the end.
In some fanfictions where Natsu becomes END, it often leads to a power - up that is both amazing and terrifying. His physical appearance might change, with more demonic features. His power level could skyrocket, making him one of the most powerful beings in the Fairy Tail universe. He might struggle with the newfound darkness within him, as END represents a very powerful and potentially evil force. This could lead to interesting storylines where his friends in Fairy Tail have to find a way to bring back the Natsu they know while still dealing with the power of END that he now wields.
It could potentially mean that in a fan - created fictional work, Naruto's story is somehow related to the end of Fairy Tail. Maybe it's a crossover fanfic where events in Naruto lead to the conclusion of Fairy Tail's story in that particular fic.
Juvia might also be a good candidate. She's deeply in love with Gray already, so the concept of her becoming the end bride could add a whole new layer of drama. Her water magic could be used in unique ways in the context of the end bride story, like creating a magical shield around herself and her loved ones as she steps into the role of the end bride.
A cool concept for a 'Fairy Tail End' fanfiction would be to have a time - travel plot. The characters could go back in time to prevent a great tragedy that was hinted at in the original series. This would involve them interacting with their younger selves and changing the course of history in the Fairy Tail world. It would also be interesting to see how they deal with the knowledge they have from the future.
