The gameplay could be affected in many ways. For instance, if traveling to the past, the environment would be different. There might be fewer advanced structures and more natural landscapes in earlier London. This would change the parkour routes as there would be less tall buildings to climb. Also, the weapons available might be more primitive, so combat would be different, relying more on swords and daggers rather than the more advanced weapons in the original Syndicate setting.
Time travel could introduce new mission types. For example, if the time - traveling Assassin has to correct historical events that were changed by an enemy's time - traveling meddling, they would have missions that are focused on restoring the original timeline. These missions could involve gathering historical artifacts from different time periods and using them to reverse the changes. The stealth aspect could also be enhanced as the Assassin has to blend in with the different time - period cultures, which could mean different clothing and behavior requirements in different eras.
One possible plot could be that the protagonist, an Assassin from the present in Assassin's Creed Syndicate, somehow gets transported back in time. Maybe they end up in a crucial moment in the history of the Assassins' Brotherhood in London. They could then use their modern - day knowledge and skills to influence events, for example, by preventing a major Templar victory that was supposed to happen in the past. This would change the course of history not only for the Assassins in the past but also have a ripple effect on the present day world they came from.
First, decide on the time period you want your character to travel to. It could be one of the well - known eras from the Assassin's Creed games like the Crusades or the Renaissance. Then, create a character with a clear motivation for time traveling. For example, they might be trying to prevent a Templar - related disaster in the past. Next, research the historical setting thoroughly so that you can accurately describe the environment, culture, and people. Don't forget to include elements of the Assassin's Creed lore, such as the hidden blade and the conflict between Assassins and Templars. Also, think about how time travel might affect the character's personality and beliefs as they experience different times and cultures.
Another possibility is a time travel where the character goes to the era of Ezio Auditore but as an outsider. They might have to adapt to the Renaissance setting quickly while also trying to figure out how their presence could potentially change the events that Ezio is a part of. Maybe they are there to prevent a Templar plot that was never fully explored in the original games.
In a way, Assassin's Creed is a time travel story. Players get to experience various eras and interact with historical figures and events, which gives the feeling of traveling through time.
Altair Ibn - La'Ahad would also be interesting. Imagine him traveling to a future time where the Assassins are almost extinct. He could use his wisdom and combat skills from the past to revive the Brotherhood and bring back the original values of the Assassins. He might have to adapt to new weapons and ways of communication, which would create a lot of interesting scenarios.
For Boruto, time traveling might make him more appreciative of the past and how hard his father worked to build the world he lives in. He could become more humble and learn from the simplicity and determination of the past generations. His friends, too, might gain a new perspective on their own lives. For example, Sarada could see how her mother was as a young kunoichi and understand her better.
In many 'Alexios Assassin's Creed time travel fanfiction', the theme of destiny plays a big role. Alexios might be sent on a time - traveling journey to fulfill a certain destiny or to correct something that has gone wrong in the timeline. Also, the theme of friendship across time is present. He forms bonds with characters from different time periods, and these relationships are often central to the story, as they help him navigate the strange new worlds he finds himself in.
If Boruto uses his rasengan in the past or future, it could have unforeseen consequences. It might be a new jutsu in that time period and could cause shockwaves through the ninja world. Sarada's chakra control, which is enhanced by her sharingan, could help her adapt more quickly to the different chakra levels in the time - travel destination. For example, if they go to a time with weaker chakra, she could still perform her jutsus effectively while Boruto might have to adjust his power output more.
Hermione's inquisitive and studious nature would mean she'd be constantly seeking knowledge during the time - travel. She'd be taking notes, asking questions, and trying to understand the historical context. For example, if they went back to the time of the Goblin Rebellions, she'd want to know all about the reasons behind it. Bill, on the other hand, being more laid - back yet brave, would be the one to jump into action when danger arises, like if they were discovered in a time they shouldn't be.
Luffy's carefree and adventurous nature would make him eager to explore the new time period. He'd probably jump into any situation without much thought, which could lead to both trouble and amazing discoveries. For example, he might accidentally disrupt an important historical event because he's so excited to see what's going on.
