For Luffy, time travel could make him more mature in a sense. He might start to understand the long - term consequences of his actions. For example, if he sees how his impulsive decisions in the past led to certain negative outcomes in the future, he could become more cautious. Robin would become even more determined in her pursuit of the truth. After seeing different historical periods, she would have more clues and might be able to piece together the full history faster.
If they travel to a time when the Straw Hat crew doesn't exist yet, Luffy could develop a sense of loneliness. But this would also fuel his determination to form the crew earlier. He might start looking for future members in the past. Robin would grow in her ability to adapt. In a new time period, she has to quickly figure out how to blend in and continue her research. This would make her more street - smart and better at handling unexpected situations.
During time travel, Luffy and Robin might discover new sides of each other. Luffy could see Robin's more vulnerable side when she is faced with historical events that are related to her past and her people. Robin, on the other hand, would be in awe of Luffy's ability to adapt so quickly to any situation in different time periods. This mutual understanding and discovery could lead to a deeper bond between them. They might also share some quiet moments where Robin tells Luffy more about the history she has studied, and Luffy listens intently, strengthening their connection.
Robin, being more reserved and knowledge - seeking, would approach the time travel with a more cautious and inquisitive mindset. She would be interested in learning about the history and culture of the different eras. Her calm nature could balance out Luffy's impulsiveness. For instance, when Luffy wants to rush into a dangerous place, Robin might stop him and suggest they gather more information first.
Luffy's rubber ability might not change directly due to time travel, but his understanding of how to use it could be enhanced. For example, if he travels to a time where there are different fighting styles, he could incorporate new techniques. Robin's ability to sprout body parts on any surface could be used in really creative ways. 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.
In 'luffy x robin lemons fanfic', Luffy may learn to value knowledge more from Robin. He could start to see the importance of understanding the past and how it can affect their present and future adventures. Robin, on the other hand, may become more adaptable to Luffy's spontaneous and sometimes chaotic way of doing things. This newfound adaptability could open up new opportunities for her to use her skills in unexpected situations, further enhancing her character development.
Their relationship could develop in a more academic way. Since Robin loves knowledge, she might start teaching Luffy about the history of the world. Luffy, being curious, would listen intently and ask simple but profound questions. This would make Robin see Luffy in a new light, not just as a captain but as someone with a thirst for knowledge as well.
Another idea is that they time - travel in a loop. Every time they go back in time and change something, it creates a new future, but then they get sent back again because the change wasn't enough to break the loop. They keep meeting different versions of their friends and enemies in different time periods. It's a never - ending cycle until they figure out the key to break the loop and return to their normal time with a better understanding of how their actions can shape the future.
In Robin and Luffy time travel fanfiction, a frequently seen theme is the exploration of history. Since they are time traveling, they get to see the One Piece world's past up close, which includes things like the origin of devil fruits or the history of certain kingdoms. Another theme is the strengthening of their bond. Through facing different challenges in different time periods together, their friendship and trust in each other grow even deeper. And of course, the theme of destiny also often appears. They might question if their time travel was fated and what role they are supposed to play in the different timelines.
Luffy would likely develop a more responsible side. He'd start to think about protecting not just his crew but also his unborn child and Hancock. Hancock, on the other hand, would become more tender and less of the cold - hearted pirate she was before. She'd focus on the well - being of the baby and her relationship with Luffy.
Hermione would likely develop a greater understanding of the roots of the wizarding world's problems. She would have to adapt her modern - day beliefs and knowledge to the different time periods. For instance, in a time where pure - blood supremacy was more rampant, she'd have to be more diplomatic in how she presented her ideas of equality. Rodolphus, starting from a dark - aligned character, could either become more sympathetic to the light side or double down on his dark beliefs depending on his experiences during the time travel. If he witnesses the harm caused by the dark magic - based society, he might change.
Merlin would likely become more cautious. In a time - travel situation, he'd know that his actions could have huge consequences for the future. For example, if he accidentally reveals too much about his magic in the past, it could change everything. Morgana, on the other hand, might see an opportunity for power. She could try to use her knowledge of the future to gain a stronger position in the past.
