One interesting idea could be exploring Happy's final moments in a very emotional way. Maybe it shows his selfless acts even in the face of death.
Perhaps in the fanfiction, Happy's death is a sacrifice to save someone he loves. It could show his growth as a character, from a carefree Exceed to a hero who is willing to give up his life. This could also cause a rift among the Fairy Tail members, some blaming themselves for not being able to prevent it, while others are inspired by his courage.
Well, it might be about how Happy's death affects the other characters in Fairy Tail. For instance, Natsu could be deeply affected and it could lead to a change in his personality or his way of fighting. His friends in Fairy Tail might also come together to remember Happy in a special way, like creating a memorial for him. It could also delve into the magical aspects related to Happy's death, such as if his magic somehow lingers or has an unexpected impact on the world of Fairy Tail.
One idea could be that Happy, in human form, discovers a new magic power that only humans can possess. He then has to learn how to control it while also dealing with the strange human emotions that come with it.
Well, one interesting idea could be unique character match - ups. For example, seeing how a Fairy Tail character would fare against an unexpected opponent from another universe in a death battle. It might also explore different power - up scenarios for Fairy Tail characters that we haven't seen in the original series, like if Natsu got a new form specifically for these death battles.
One idea could be that Happy's death shatters the Fairy Tail guild. Natsu, being his closest friend, goes into a deep depression. The guild loses its usual cheer and the members struggle to come to terms with the loss. They might hold a grand memorial for Happy, and throughout the fanfiction, it could show how each character copes in their own way, like Lucy writing in her diary about all the memories she had with Happy.
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. Or, write a story where the characters swap powers. So, Erza would have Lucy's celestial magic and Lucy would have to use Erza's requip magic. This would lead to a lot of comical and also challenging situations for them. Also, you could write a fanfic about the guild taking on a mission in a completely new and strange land, filled with magic they've never seen before.
One idea could be exploring an alternate universe where the main characters have different magic abilities. For example, Natsu could have ice - based magic instead of fire. Another idea is to focus on the backstories of the minor characters in more depth, like how they came to join Fairy Tail. A third idea would be to create a time - travel fanfiction where characters go back in time to change a significant event in the Fairy Tail world.
One idea could be exploring an alternate universe where the main characters have different magic powers. For example, Natsu could have ice - based magic instead of fire. Another idea is to focus on a backstory for a minor character, like how they came to join the guild. Maybe a story about a character's journey to find a long - lost magical artifact that has a connection to Fairy Tail's history.
You could write a Fairy Tail fanfiction centered around a character's growth. For instance, take Wendy. You could write about her journey to master new and powerful dragon - slayer magic, facing challenges that force her to grow not only in power but also in confidence and leadership skills. It could involve her going on a solo adventure to a far - off land to learn from a reclusive dragon.
One idea could be Wendy going on a solo adventure to a far - off land in the Fairy Tail universe to discover a new type of magic. She could meet unique characters and face challenges that test her skills and growth as a mage.
In some fanfiction, a human who is an artist finds a fairy tail. The fairy in the tail has the power to bring art to life. The human and the fairy work together to create a beautiful, magical art gallery. They invite other humans and fairies to see their creations, spreading happiness and harmony between the two worlds.
One interesting aspect could be the unique character interactions. In fanfiction, the relationships between the characters from 'Fairy Tail' can be explored in new and unexpected ways. For example, Happy's character might be developed further in a roasting scenario, showing a different side of his personality. Maybe he gets into comical arguments with other characters, which can add a lot of humor to the story.
