Pepper Potts could also be very interesting. If she travels back in time, she could use her business acumen and knowledge of the future Stark Industries to make significant changes. She might also have a different relationship with Howard Stark, influencing the Stark family in new ways.
Mr. Incredible would be really interesting. He's already a strong and experienced hero. If he travels through time, he could use his brute strength in different historical contexts. He might have to adapt his fighting style in eras with different technologies or combat techniques. For example, in a medieval - like time period, he'd have to rely more on his physical skills without his modern gadgets. Also, seeing how he reacts to meeting his ancestors or versions of himself from different times would add depth to the story.
Reaper could also be an interesting focus. His dark and mysterious past could be explored further through time travel. He could go back to the time when he was still Gabriel Reyes, before the transformation. This could show the events that led to his current state, and perhaps in a time travel scenario, he could even have a chance to change his fate. It would be a story full of drama, mystery and action as he grapples with his past self and the decisions that led him to become Reaper.
I think Kai would be a great focus. His hot - headed nature could lead to some really chaotic time - travel situations. For instance, if he travels back to a time when the Fire Temple was in danger, he might rush into action without fully understanding the consequences, and end up changing the future of the Fire Element in Ninjago in unexpected ways.
Captain America would be really interesting. His moral compass and leadership skills in a time - travel scenario would be fascinating. He has to deal with the changes in the past that the time travel causes, and also make sure the other Avengers stay on the right path. He might struggle with seeing his old world again and having to make choices that could change it further.
Kuroko himself would be very interesting. His quiet and somewhat mysterious nature could be explored in new ways with time travel. He could go back to a time before he met the Generation of Miracles and use his new - found knowledge to help his younger self become an even better player sooner.
Natsu could be really interesting. Imagine him traveling back in time and accidentally causing chaos because of his impulsive nature. He might try to use his fire magic in a time when it was less understood or accepted, and have to deal with the consequences. He could also meet younger versions of his friends and have heart - warming or hilarious interactions.
Kakashi would be really interesting. He has a lot of past experiences and knowledge. In a time - travel scenario, he could use his wisdom to guide Team 7 through different historical events. He might also have some personal moments, like seeing his old friends or mentors in the past. His sharingan could also play an important role in understanding the new situations they find themselves in during the time travel.
Definitely Harry Potter himself. His journey through time could be a way for him to gain more understanding of his parents and the events that led to their deaths. He could also try to change some things in the past to make the present better. For example, he could try to prevent Voldemort from ever becoming so powerful in the first place. And seeing Harry interact with the people from the past, like his grandparents or young Dumbledore, would be really fascinating.
Luffy would be really interesting. His carefree and adventurous nature would make his reactions to different time periods really fun to explore. He might try to befriend everyone he meets in the past or future, regardless of the consequences. His simple view of things could also lead to some unexpected changes in the timeline. For example, he might accidentally start a new pirate crew in the past or inspire a revolution in the future just by being himself.
Hermione would be really interesting. She's so intelligent and studious. If she traveled back in time, she could use her knowledge of magic history and spells to make a big impact. For example, she might be able to help the Order of the Phoenix in new ways during the First Wizarding War or she could introduce some modern magical concepts to the wizards of the past.
