One Piece 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 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.

One idea could be Ace traveling back to the time when Gol D. Roger was still alive. He could witness the events that led to Roger's surrender and execution, and perhaps even interact with the Pirate King. This would give him new insights into the world of piracy and his own place in it.

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.

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.

Perhaps a magical curse befalls the crew that causes several female characters in the One Piece world to be irresistibly drawn to the male members of the Straw Hats. This could lead to all sorts of chaos as the crew tries to deal with these new, unexpected relationships while still pursuing their main goals.

A plot could involve a supernova teaming up with an unexpected character, like a former villain who has a change of heart. They could go on a quest to find a long - lost treasure that has a special connection to the supernova's past. This would not only create an interesting dynamic but also explore the backstory of the supernova character more deeply.

Well, a plot could involve a vampire character who was once a regular pirate but got turned into a vampire. This vampire pirate then has to deal with his new cravings while still trying to achieve his original goals in the One Piece world, like finding the One Piece. And maybe there's a group of vampire hunters in the One Piece world who are after him.

Another idea is that they time travel to a random point in the past, like when Gol D. Roger was still alive. Luffy would be excited to meet the Pirate King. Roger might see something special in Luffy and give him some cryptic advice. Robin could ask Roger about the secrets he knew about the world's history. This encounter could have a huge impact on Luffy's journey and how he views his role as a pirate.

One interesting plot idea could be Saitama traveling back in time to his pre - hero days and trying to prevent Genos from becoming a cyborg. Another could be a villain traveling back to stop Saitama from ever becoming a hero in the first place. Maybe time - traveling heroes from the future come to help present - day heroes fight stronger threats.
