One Piece Ace Time Travel Fanfiction: What are some interesting plot ideas?

Well, a really cool plot could be about a time - traveling device falling into the hands of a villain. This villain then goes back in time to stop Luffy from ever starting his journey. The Straw Hats would then have to find a way to also travel back and stop the villain. Or, a character could travel back in time and accidentally change something small that has huge ripple effects on the present One Piece world, like changing the location where a Devil Fruit was found, which could change who got what power.

One interesting plot idea could be a character from the present-day One Piece world traveling back to the time of the Void Century. They could discover the true history of the world and the origin of the Ancient Weapons, which would completely change the power dynamics in the present. Another idea is a character from the past traveling to the future and being shocked by how the world has developed, with new islands, new Devil Fruits, and different pirate crews ruling the seas.

One idea could be Ace crossing over into a modern - day world where he has to adapt to new technologies while still having his devil fruit powers. He might get involved in some sort of street racing using his fire powers to boost his vehicle.

A great plot could be that the ace in the fanfiction discovers a time-traveling device by accident. They then use it to travel to different historical events. They might end up changing something small in the past that has a huge impact on their present world. For instance, they could accidentally prevent an important scientific discovery from happening in the past. Now they have to travel through time again to fix what they've broken. This creates a lot of suspense and adventure.

One interesting plot could be that Ace, Sabo, and Luffy travel back in time to when Gol D. Roger was still alive. They could try to prevent certain events that led to the current state of the One Piece world. Maybe they want to stop the tragedies that befell their families in the past.

Well, he could time - travel to a point where the Straw Hats first formed but he's the only one who remembers the future. This would lead to some really funny and interesting situations. He might try to prevent some of the early hardships they faced, like the fight with Buggy. Or perhaps he travels to a time during the Void Century and discovers secrets that could change the course of the current One Piece world. He then has to figure out how to bring this knowledge back to his own time without causing chaos.

One idea could be that Female Luffy and Ace team up for a special treasure hunt. They might discover a long - lost island that holds a powerful Devil Fruit that has unique abilities. Another plot could involve them facing a new and powerful enemy together, and during the battle, they learn more about each other's dreams and pasts. For example, they could find out about a connection between their families that they were previously unaware of.

A great plot idea could be that the OC is a healer who saves Ace's life after a particularly brutal fight. Ace is initially distrustful but as he recovers, he sees the kindness in the OC. They then go on a journey to find a rare herb that can cure a disease that is spreading among the pirates, and along the way, their relationship blossoms.

A possible plot in the fanfiction could be that they time travel to a point where the Straw Hat crew has disbanded in the future due to some great tragedy. Luffy and Nami then have to figure out what went wrong and change the course of history to reunite the crew. Or perhaps they go back to a time when Nami was first forced to work for Arlong. Luffy, with his knowledge of the future, could find a way to free Nami much earlier and change the course of her life and the crew's development.

Ace would likely become more mature. If he travels to the past and sees the struggles of previous pirates, he'd gain a deeper understanding of the pirate world's history and his role in it. This new knowledge would make him less impulsive.
