Well, often in fanfiction about Lucy's brother, he could be a bit of a mystery figure. Maybe he has a secret past or some hidden powers. He could be someone who has connections to an unknown part of the Fairy Tail world. For example, he might be involved with a secret guild that has a big influence on the main story but has been kept under wraps. He could also be shown as having a strained relationship with Lucy at first, due to some past misunderstandings, but then they gradually reconcile as the story progresses.
In some fanfictions, Lucy's brother is portrayed as a brilliant strategist. He uses his intelligence to help Fairy Tail in difficult situations. He might not have the most powerful magic in terms of raw strength, but his ability to plan and outwit opponents makes him a valuable asset. He could also be a bit of a loner, preferring to work behind the scenes rather than being in the spotlight like many of the Fairy Tail members. He may have his own reasons for staying in the shadows, perhaps to protect Lucy from certain threats that he anticipates.
In many fanfictions, Lucy's love for Natsu is often shown through her unwavering loyalty. She stands by him in battles, always believing in his strength. For example, she might heal his wounds after a tough fight, a simple yet powerful display of her care.
In some fanfictions, he is a mentor - like figure. He teaches Mavis or other young wizards important lessons about magic, life, and the values of Fairy Tail. This could include things like the importance of friendship in magic, which is a central theme in the Fairy Tail series.
To portray their friendship better, they could be shown sharing secrets. Maybe there's a secret place in the guild that only they know about, and they go there to share things like their first crushes or embarrassing moments from their childhood. Also, having them give each other meaningful gifts, like Lucy giving Lisanna a special keychain she made herself, and Lisanna giving Lucy a handmade scarf, would also strengthen the portrayal of their friendship.
One common storyline is the reunion plot. Lucy's brother has been away for a long time, and when he returns, there are all kinds of emotions and revelations. Another is the protection storyline, where he devotes himself to protecting Lucy from a powerful enemy.
In some Fairy Tail fanfictions, aphrodisiacs might be used as a plot device to create comical situations. For example, a character might accidentally ingest an aphrodisiac - thinking it was a normal potion - and start acting in an overly affectionate or flustered way. This can add an element of chaos and humor to the story.
Some fanfictions portray Ophis as a misunderstood character. Despite her fearsome power, she may actually have good intentions deep down. For instance, she could be trying to protect something or someone in the Fairy Tail world but her methods are misconstrued by the guild members at first.
In Fairy Tail fanfiction, strength can be portrayed in many ways. Sometimes it's about the physical power of a character, like Natsu's fire - based attacks being super - strong. Other times it's the strength of their friendships. For example, when the guild members come together to fight a common enemy, their combined strength is more than just their individual powers added up. It shows that in the world of Fairy Tail fanfiction, emotional bonds can be a great source of strength too.
In Fairy Tail fanfiction, envy can be shown in various ways. For example, a character might envy another's magical powers. They could be jealous of how easily a friend can perform powerful spells while they struggle with their own weaker abilities. This envy can lead to inner turmoil and sometimes even conflict within the story.
In some Fairy Tail fanfiction, Natsu's age is portrayed as a bit older. This is often done to give him more experience and a more developed personality. For example, he could be in his twenties, having been through more adventures and having a deeper understanding of magic and the world around 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.
