Zoro would probably be more of a lone wolf in the past. He was always focused on becoming the world's greatest swordsman. In the past, he might be even more determined, seeing the great swordsmen of old. He could be less patient with Luffy's antics at first, but gradually come to respect his leadership more as he realizes Luffy's potential. His sense of honor would be even more pronounced, especially when dealing with the sword - related traditions of the past.
Sanji in the past might be more bitter about his family situation. In the present, he's starting to come to terms with it, but in the past, he'd be right in the middle of the turmoil. He'd be more likely to lash out at those who remind him of his family's wrongdoings. However, his kindness towards women would still be there, but it might be a bit more guarded as he's not as confident as he is in the present. Also, his cooking skills would be more raw, and he'd be eager to learn from the great chefs of the past.
Harry's personality is deeply influenced by his experiences with Voldemort. In the past, he might be more carefree initially but would quickly become a protector when faced with threats.

This could lead to a revolution in the way magic was taught in the past. Ron, with his down - to - earth nature, would probably make friends easily. He could introduce muggle - like concepts to the wizarding world of the past, which might change their view of non - magical people.
Another plot twist could be Zoro traveling back in time and finding out some long - lost secrets about his family or his swordsmanship heritage.

For example, he might want to find more about the origin of this technique and spread it in his own time.
Luffy's rubber ability might not change directly due to time travel, but his understanding of how to use it could be enhanced.

If they travel to a time with different architecture, she could use the structures to her advantage in combat or for exploration in ways she hadn't thought of before.
James might become more cautious. The future could be full of things he doesn't understand, so he might not be as brash as he was in his own time.
If ASL time - travels, Luffy's relationship with his brothers would be strengthened in new ways. They would have to rely on each other more as they face the unknowns of the past. For example, Ace might see a younger Luffy and be even more protective.
The time travel could put some strain on their relationships at first. Harry might be more focused on seeing his godfather again, Ron could be a bit jealous if Harry's attention shifts too much, and Hermione would be constantly worried about the rules of time travel.

They'd also have to hide their true identities from the people in that time, which would require a lot of trust among them.

In the past, Luffy would likely be even more of a novelty. His fearless and somewhat naive attitude would stand out in an era where pirates were perhaps more cutthroat and calculating. He might bring a sense of hope and a different way of thinking to those around him. Law, in the past, could be seen as a bit of an enigma. His quiet and strategic nature might make him seem like a dangerous wildcard.

Law might be more intrigued by the future's medical advancements and would be eager to learn and incorporate new knowledge into his own skills.
Sakura might become more reserved in an older time period as the social norms were different. She is used to the more modern and open ninja world.
