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 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.
Well, in some fanfictions, a plot twist could be that Future Lucy actually has a hidden power that she didn't know about until she traveled to the past. This power then becomes crucial in solving the problems in the past and also has implications for her own future. Also, there might be a plot twist where she discovers that the reason for her coming to the past was not what she initially thought. Maybe it was all part of a bigger plan by a character who has been manipulating events from the shadows all along.
One possible scenario could be that she sacrifices herself to save her friends from a powerful dark magic. In the chaos of a huge battle, she might use all her magic power to create a shield that protects everyone else but drains her life force completely.
