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, 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 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.
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?
In most cases, watching (reading) fanfiction is legal as long as it doesn't violate copyright laws in a major way. Fanfiction is often a derivative work, and as long as it's not being sold commercially without permission from the original copyright holder and is more of a non - profit creative exploration of existing works, it's usually okay.
Jon Snow is often a popular character. His mysterious origin and heroic nature make him a great focal point in fanfiction. He could be given new adventures or relationships in the future - themed stories. Daenerys Targaryen is also popular. Fans might explore what she would do if she had knowledge of the future, like avoiding some of the mistakes that led to her downfall in the original series. Another popular one is Tyrion Lannister. His wit and intelligence can be further explored in the context of future events in Westeros.
I think Weiss could also be central. She comes from a powerful family and has a lot of influence. In a story about watching the future, her knowledge of politics and her strategic thinking could play a big role. Also, her relationship with the other characters, especially Ruby, would be important in how they all react to what they see in the future. Blake might also be central as she has her own complex backstory and her views on the relationship between humans and Faunus could be greatly affected by seeing the future.
Some of them might be shocked. Tony Stark, for instance, might immediately start thinking of ways to use technology to change what he saw. Steve Rogers would probably be more concerned about the moral implications of interfering with the future.
He would likely be very curious. Naruto has always been eager to learn and explore new things, so seeing future fanfiction would be like opening a door to a new world of possibilities for him.
They might be confused at first. Fanfiction can be wild and different from their real experiences.
Naruto is a very empathetic character. So while watching Attack on Titan fanfiction, he would likely feel for the characters who are suffering. When he sees the destruction caused by the Titans and how the people in the story are trying to survive, he would be reminded of the hardships his own village has faced. He might even start to come up with strategies in his head to help the characters in the fanfiction, just like he does when he's in a tough situation in his own world.
