One interesting concept could be how the characters adapt to the past's different social norms. For example, if they come from a more modern time, they might struggle with the lack of certain technologies or the strict moral codes of the past era.
Perhaps the alteration of historical events is an interesting aspect. In this fanfiction, the order traveling to the past might accidentally or intentionally change things that were supposed to happen, which could lead to a whole new chain of events and a different present or future.
Another possible main character could be a historian or a scholar within the order. Their knowledge of the past could be crucial in helping the order navigate the historical period they travel to, and they might also be on a personal quest to discover something that has been lost in time.
One interesting concept could be time - loop travel. In past travel fanfiction, characters might find themselves stuck in a repeating cycle of past events, and they have to figure out how to break it. For example, in a story set in a historical era, a character might keep reliving the same day of a significant battle, and through their repeated attempts, they learn more about the true nature of the battle and the people involved.
In this type of fanfiction, a cool plot could be Harry traveling back to the time when the founders of Hogwarts were alive. He could learn ancient magic directly from them. He might also get involved in the politics of that time, helping to shape Hogwarts' early rules and traditions. This would not only change his own future but also the future of the entire wizarding world as he brings back forgotten knowledge and wisdom from the past.
One interesting concept could be how the characters' relationships might change if they are sent back in time. For example, Naruto might use his future knowledge to prevent certain tragedies from happening to his friends, like Sasuke's fall to the dark side. This could lead to a completely different dynamic between them.
One interesting concept could be the idea of Naruto having a past life as a powerful ninja from an ancient clan. Maybe he had different jutsu or abilities that he unknowingly carried over into his current life.
In time travel to the past fanfiction, the idea of changing history for personal gain can be really engaging. For instance, a character might go back to the past to invest in a company before it becomes huge, like Apple in its early days. Another interesting aspect is the cultural differences. If a character travels back to a different era, they have to adapt to the different social norms, fashion, and language of that time. This can lead to some really funny or poignant moments in the story. Additionally, there are often love stories involved. A character might fall in love with someone from the past, which creates a complex situation as they try to navigate their relationship while also dealing with the implications of time travel.
One interesting plot could be Naruto using his future knowledge to prevent the Uchiha massacre. He might try to change Itachi's situation and find a way to resolve the conflict between the Uchiha clan and the village without all that bloodshed.
One interesting concept could be how Naruto's past life memories change his relationships. For example, if he remembered being a great warrior in his past life, he might approach his training with Sasuke differently, seeing it as more of a friendly rivalry between two equals from different lifetimes. Another concept could be how his past life knowledge affects his view of the ninja world. Maybe he has memories of different forms of chakra usage that were lost in the current era, which could lead to him revolutionizing the way ninjas fight.
One interesting concept could be the exploration of Spider - Man's inner struggles with past sins in a more in - depth way than in the original comics. It might show how his actions have long - lasting consequences on his relationships and his own psyche.
One interesting concept could be the combination of different character abilities from Fate Grand Order and RWBY. For example, seeing how a Servant's Noble Phantasm might interact with a RWBY character's semblance. Another concept could be the crossovers in the storylines, like how the overarching plot of Fate Grand Order, which often involves saving the world from various threats, could mesh with RWBY's fight against the Grimm. Also, the character relationships that form between the two universes' characters can be really engaging, such as a Fate character forming an unexpected alliance with a RWBY team member.
