Often, the theme of self - discovery is present. By changing the past, Sakura gets to learn more about herself and her capabilities. Also, the theme of preventing a tragedy is quite common. Maybe there was a big disaster in the original timeline that she aims to avoid. In these fanfictions, the exploration of the butterfly effect is also a thing. Every change she makes in the past has consequences in the future, and this can lead to interesting plot developments.
One common way is that Naruto becomes more romantic. He might start writing poems or giving Sakura flowers, which is a far cry from his usually rough - and - tumble self. This is his way of showing his love for her in the fanfiction world.
I'm not sure of specific 'sakura changes the past fanfiction' titles off - hand. You could try searching on fanfiction websites like Archive of Our Own or FanFiction.net. They usually have a large collection of fanfictions on various topics.
One possible change is that she becomes more self - reliant. In the Wave arc, she saw the limitations of her own abilities. So in fanfictions, she might start to focus on self - improvement. Maybe she begins to practice her combat skills more rigorously, so that she can hold her own in battles without always depending on Sasuke or Naruto.
At first, Sasuke might be hesitant. He has been on his own journey for so long, and coming back to someone means opening up again. But as he gets closer to the idea of having Sakura back, he could start to feel a sense of longing. He might remember the good times they had and feel regret for leaving her in the first place.
Another interesting change could be Sirius introducing a new magical element or concept into the story. He might bring in a long - forgotten spell or a magical artifact that has the power to either help or harm the characters. This would not only change the plot but also force the other characters to adapt to this new aspect of their world.
In some Pokemon League Changes Fanfiction, the location of the league battles could be different. They might not be held in the traditional arenas but in more natural or unique settings. This could affect how trainers prepare their Pokemon for battles. The rewards for winning in the league could also change. Instead of just trophies and titles, trainers could receive rare Pokemon eggs or exclusive training items that can boost their Pokemon's growth significantly.
Perhaps he would change to Naruto Storm. 'Storm' can represent his powerful and sometimes tempestuous nature. In the series, Naruto has shown great strength and determination that could be likened to a storm, which is both destructive and at the same time a force of change.
Typically, the young and upcoming trainers are the ones most affected. They have to quickly adapt to the new rules and changes in the Pokemon League. For instance, a novice trainer who was just getting used to the old battle format now has to learn a new one.
