Lucy joining Fairy Tail as a kid would lead to a significant evolution of her character. In the beginning, she might rely too much on the kindness of the older members. But as she gets older, she would start to assert herself. She'd develop her own unique style of magic. Through the various quests and battles, she'd become more self - reliant. Also, her relationships with the other members would shape her. For instance, her friendship with Happy might make her more optimistic, while her rivalry with some other young wizards could fuel her determination to improve and prove herself within the guild.
She would probably be more innocent and naive at first. But as she experiences the adventures and challenges in Fairy Tail, she would gradually become more confident and brave. For example, facing her first real battle might be terrifying, but it would also be a huge step in her growth.
If Kakashi joined Fairy Tail, the story would likely revolve around his integration. He'd be a mystery to most of the members at first. His Sharingan would be a source of both awe and suspicion. The story could develop as he tries to find a way back to his own world while also helping Fairy Tail. He might get involved in training some of the younger members, like Wendy, teaching them how to better analyze their opponents. And his presence could also attract the attention of stronger enemies who see him as a threat or a valuable asset.
If Lucy never joined Fairy Tail, the friendships and relationships among the characters would form in a very different way. Also, many of the story arcs might not unfold as they do in the original plot.
Their relationship could start with mutual suspicion. Lucy is a member of Fairy Tail, and Midnight is from a different, often opposing group. But as they interact more, they might find common interests. For instance, they could both be interested in a particular type of magic theory. This shared interest could be the starting point of them gradually warming up to each other.
Lucy would likely become more independent. In high school, she'd face new challenges without her usual Fairy Tail comrades always by her side. This would force her to rely on her own wits and celestial spirit powers more often.
At first, it could be a relationship of mistrust. Lucy might be scared of Laughing Jack's appearance and his unpredictable behavior. But as they are forced to work together on various tasks or face common enemies, they start to understand each other better. For instance, Laughing Jack might show a protective side towards Lucy during a dangerous mission, which makes her see him in a new light.
In many fanfictions, Future Lucy starts off as a determined and somewhat broken character. She has seen the destruction of her world and is desperate to change it. As the story progresses, she learns to trust the people in the past. For example, she might initially be hesitant to work with Natsu and the others, but as she sees their kindness and determination, she becomes more open. This helps her character grow from a lone wolf trying to save the world to someone who is part of a team.
If Sakura joins the Akatsuki in fanfiction, her character would likely become more self - reliant. In Konoha, she had friends and mentors to rely on. But in the Akatsuki, she would be among people who are not as trustworthy. This would force her to rely on her own skills and instincts more. Also, she might become more secretive. Since she's in a group that's not exactly friendly to Konoha, she'd have to keep a lot of things to herself.
The story could develop in many ways. Maybe the SI - as - Lucy would start to modernize the Fairy Tail guild a bit. She could introduce new ideas based on her previous life's knowledge. For example, better ways of communication within the guild or new training methods.
The story could focus on their journey to find a new place to belong. They might meet new allies along the way who have different values and magic abilities, which would add new elements to the story. For instance, they could encounter a group of mages who use music as their form of magic.
Trunks might start off as a bit of an outsider. But as he gets involved with the Fairy Tail guild, he could become more open and friendly. He'd learn the value of friendship like the Fairy Tail members do.
