Ryosuke would likely analyze the situation. He'd study his past self to see how he could have improved even more in the past. He might be a bit critical at first, but then realize that his past self was on the right track and that all the experiences he had, both good and bad, led him to become the racer he is in the present. He might also be curious about how his past self would react to his current racing skills and knowledge.
Captain America would probably be very reflective. He might see his past self as a reminder of his long journey and how much he has changed. He could try to offer some words of wisdom to his younger self.
Both of them might also feel a sense of unease. Seeing a version of themselves from the future could make them realize how much they are changing and how uncertain their future really is. It could also make them question their current identities and goals. They might start to have an internal struggle as they try to reconcile their present selves with the potential future versions they are seeing.
Kite would approach time travel with a strategic mindset. He'd be looking for ways to gain an advantage, like finding new duel monster cards or techniques that he could bring back to his own time. Rio would be more concerned about the well - being of others. If she saw people in trouble in the time she traveled to, she'd try to help. Tori would be in awe. She'd be fascinated by the different cultures and dueling styles she'd encounter, and she might document her experiences in a journal.
Touka would be more cautious. She has always been a bit more guarded. She might be skeptical of the whole time - travel thing at first. But once she realizes it's real, she would focus on how it can benefit the ghoul community. Maybe she would use it to learn about future threats to ghouls and find ways to counter them.
Well, when it comes to time travel in One Punch Man fanfiction, Saitama could be rather indifferent. He's so powerful that he doesn't really fear new situations much. Genos would be all about gathering data. He'd study the time - travel device if there is one, and try to understand the implications of the time period they've landed in. For the other heroes, like Bang, he might be more cautious. He'd use his martial arts wisdom to assess the new environment and figure out if there are any new threats or allies. And the villains? Well, they might see time - travel as a chance to gain more power or change the power balance in their favor.
Some characters might be amused. They could find the different interpretations in the fanfiction entertaining and might even share it with other characters.
The crew's reaction would depend on the situation. If they meet Dragon in a dangerous situation, they would be relieved to have such a powerful ally. If it's a more casual meeting, they would be eager to learn more about him. Luffy would be overjoyed, and his happiness would be contagious. The rest of the crew would gradually warm up to Dragon, and they might start sharing their own stories and dreams with him, forging a new connection within the One Piece universe.
Their interaction would be very interesting. They would probably be very curious about each other. The present - day BTS might want to give advice to their past selves, like how to deal with stress better during their early days.
Some characters in Z Nation might be very skeptical at first. They've been through so much in the apocalypse that the idea of time travel would seem far - fetched. For example, Murphy might think it's a trick by his enemies. Others, like Warren, would be more open - minded. She would probably try to see if the time traveler could help them in their fight against the zombies. And then there are the more desperate characters who would immediately see the time traveler as a possible solution to all their problems, like some of the survivors in the refugee camps.
Prompto would be both excited and scared. He's always been a bit of an adventurer, so the idea of time travel is thrilling. But he'd also be worried about messing things up. He might be the most empathetic towards the people in the past, trying to understand their situations better than the others.
