Arthur Morgan would be a fascinating character to time - travel. Imagine him in a modern - day city. He'd be so out of place with his cowboy ways. He'd probably be amazed by the tall buildings and the amount of people. And his sense of honor and justice might lead him to get involved in modern - day issues like helping the homeless or standing up to bullies.
I think Dutch van der Linde would be an unexpected but great choice. His charisma and leadership skills could make for some really interesting scenarios. If he time - traveled, he might try to take over a modern - day organization or group, using his old - fashioned charm and manipulation tactics. Or he could be shocked by the modern concept of law and order and try to fight against it in his own way.
Kazama Chikage might be an interesting choice as well. He is a powerful and somewhat arrogant character. If he time - travels, perhaps to a past era where his clan was even more powerful, he could try to change history to make his clan even more dominant. Or if he travels to a future where his power is nothing compared to modern technology, his struggle to come to terms with his new position in the world would be an interesting plotline.
Iroh would be fascinating to see time - traveling. He has so much wisdom already. If he traveled to different times, he could share his knowledge and perhaps change some key events. He could also gain more insights from other time periods, which would further enrich his already deep understanding of the world.
Eleven could be a likely candidate. Given her powerful psychic abilities, she might accidentally or purposefully time travel. Her powers have always been a bit unpredictable, and time travel could be an extension of that. She has a strong connection to the Upside Down, so she might be sent back in time to learn more about its origin or how to stop it.
Daenerys Targaryen. She has a strong will and a mission to claim the Iron Throne. If she time - traveled, she could meet her ancestors and learn from their successes and failures. She could also try to prevent the downfall of her family in the past, which would have a huge impact on the present state of Westeros in the fanfiction world.
I think Izuku Midoriya would be really interesting. He's the main character and has so much knowledge about the heroes and villains. If he time - travels, he could use his understanding of quirks and combat strategies to change the past or future in significant ways. For example, he could go back and give advice to All Might when he was younger, which might change how All Might deals with villains later on.
Ahsoka Tano would be a great choice. She has a complex history within the Clone Wars. If she were to travel back in time, she could interact with her younger self. She might be able to pass on wisdom she gained from her later experiences, like how to better handle the politics within the Jedi Order and the Galactic Republic.
Shikamaru might be the most influential. He is known for his intelligence. In a time travel situation, he could quickly analyze the situation, come up with plans, and predict the consequences of different actions. His strategic mind would be crucial in dealing with any unexpected events during the time travel, whether it's in the past or the future.
Another plot might involve a character from the game's time traveling forward to the modern day. They would be shocked by the technology and the different social norms. For example, they might see a car for the first time and think it's some kind of metal beast. They could then try to adapt to this new world while also longing for their own time.
Rick would be an interesting choice. He has so much leadership experience. If he were sent back in time, he could use his knowledge of survival and leadership to better prepare society for the impending apocalypse. He could start stockpiling weapons, food, and building secure shelters.
Ruby would be really interesting. Since she's the main character, seeing her go back in time and interact with her younger self or her mother could be really emotional and full of character development. She could also use her knowledge to make herself an even better Huntress at an earlier age.
