One common theme is sacrifice. Characters often give up their lives for the greater good of the guild or their friends. For example, in many stories, a hero might die to save the guild from destruction.
In some Fairy Tail fanfictions where Juvia dies, it could be a very emotional and impactful scenario. It might be due to a powerful enemy she couldn't defeat, sacrificing herself to save Gray or her friends. Her death could lead to Gray's character development, making him more determined to fight against the forces that took Juvia from him.
Well, many fanfic writers take creative liberties with Lisanna's death. Some might show it as a heroic sacrifice, where she gives up her life to save others in the guild. This could then be a source of inspiration for the other characters, pushing them to be better and stronger. Others may depict it in a more tragic and unexpected way, perhaps due to a misunderstood magic spell or an unforeseen enemy attack.
One great 'Fairy Tail Death Dragon Slayer' fanfiction is 'The Ascent of the Death Dragon Slayer'. It has an interesting plot where the main character, a Death Dragon Slayer, has to face challenges that are different from the normal Fairy Tail adventures. The author does a great job of portraying the character's struggle with their unique powers.
One possible plotline could be that Erza sacrifices herself to save her guildmates from a powerful dark magic attack. She stands in the way, knowing it will cost her life, but she does it to protect those she loves.
One possible scenario could be Juvia sacrificing herself to save Gray. In the heat of a battle against a powerful enemy, Juvia might use her water magic to shield Gray from a fatal attack, but at the cost of her own life. Another could be that she succumbs to a dark magic that she was trying to fight off alone, not wanting to endanger her friends. Maybe she gets caught in a cross - fire between two extremely powerful magic users and her body is too weak to withstand the impact.
One possible scenario could be Levy getting caught in a powerful dark magic spell during a battle. The spell slowly drains her life force as she tries to fight it off but fails. Another could be that she sacrifices herself to save her friends in the Fairy Tail guild. She might jump in front of a fatal attack meant for one of her beloved comrades.
Another concept might be the re - imagining of existing Fairy Tail battles with different rules or circumstances. This can change the outcome and give a fresh perspective on the characters' abilities. In some fanfictions, they might introduce new magic types during these battles which adds an element of surprise.
The Fairy Tail guild members might feel guilty. If Naruto had befriended some of them, they would be devastated. There could be a split in the guild, with some members blaming others for Naruto's death. For example, if a hasty decision by a guild leader led to Naruto being in a dangerous situation where he died, there would be internal strife.
