Perhaps the fanfiction could be about a device or power that allows the characters to watch the future unfold. They could witness future battles and use this knowledge to train or prepare better. Like, if Mikasa saw herself losing a fight in the future, she could work on her skills to change that outcome.
It could involve the characters seeing visions of a future where the Titans are finally eradicated. Maybe they see a world where humanity has rebuilt and is living in peace without the constant threat of Titans. For example, Eren might see a future where his friends are alive and happy, and this could change his actions in the present timeline.
Another possibility is that it's not just about the main characters. It could show how the world as a whole in Attack on Titan is affected by the ability to watch the future. Different factions might fight over this power, and it could lead to a whole new set of political and power struggles within the walls.
One possible plot point is that the characters start to question their own fates and destinies. Since they are watching the future, they might wonder if everything is already set in stone or if they still have the power to change things. This internal struggle could be a central theme in the fanfic. Also, the fanfic could explore how the knowledge of the future affects the military strategies against the Titans. Do they become more aggressive or more cautious? How does this new knowledge impact their training and the development of new weapons?
I think Levi could benefit as well. His combat skills are already top - notch, but seeing the future could help him anticipate enemy attacks even better. He could train his squad more effectively based on the future battles he witnesses, ensuring their survival and making them even more formidable against the Titans.
Well, if RWBY characters were to watch Attack on Titan fanfiction, they might be really confused at first. Ruby, with her innocent nature, would probably be wide - eyed and full of questions. Weiss might be a bit critical, analyzing the writing style and how it compares to the original Attack on Titan. Blake could be more interested in the relationships and character dynamics within the fanfiction, seeing as she has a penchant for complex stories. Yang, on the other hand, would probably be making jokes about the more outlandish parts of the fanfiction.
Well, it's likely that Eren would still be one of the main characters. After all, he's a central figure in the original 'Attack on Titan' story. He might be the one most affected by seeing the future and could play a crucial role in trying to change it.
It could involve Percy facing new challenges related to the concept of balance. Maybe he has to deal with a Titan who is disrupting the natural order. For example, the Titan might be causing chaos between the mortal and the demigod worlds, and Percy has to find a way to stop it.
A great plot for such a fanfic could be that Mikasa's Titan form is a result of a connection to an ancient Titan power. As she becomes a Titan, she starts to have visions of the past, of how the Titans came to be. She then decides to use this knowledge and her new form to try and end the Titan - human conflict once and for all. Along the way, she has to face her friends who are initially scared of her but eventually come to accept her new form as she proves that she is still the same Mikasa deep down, just in a different body.
The plot could involve Hermione traveling to a future where the wizarding and muggle worlds have merged. She would then have to adapt to this new reality. She might see muggles using magic in some form, or wizards having to abide by muggle laws. This would be a huge change from what she's used to. Also, she could be on a mission to fix something in the future. Maybe there's a dark magic that's threatening to destroy both worlds, and she has the knowledge from her time to stop it.
Well, perhaps she is reborn as a member of a noble family in the Attack on Titan world. This gives her access to resources and influence. She could use this new - found power to reform the military or start research into alternative ways to deal with the Titans. She might also get involved in the complex political web within the walls, trying to bring about peace and unity among the different factions.
One possible plot could be that Naruto and his friends somehow end up in the world of Attack on Titan. Naruto's ninja skills would be really useful against the Titans. For example, his shadow clone jutsu could be used to distract the Titans while the Survey Corps tries to attack their weak points. Also, Sasuke's sharingan might be able to see some hidden details about the Titans that the people in the Attack on Titan world don't know. It would be an epic adventure as they combine their powers to fight the common enemy - the Titans.
Well, it could be about Sephiroth using his incredible combat skills from Final Fantasy in the world of Attack on Titan. Maybe he teams up with the Survey Corps to take on the Titans. He might use his Masamune sword to slice through the Titans' nape with ease, bringing a new level of badassery to the fight against the Titans.
