Well, in the time - travel scenario, their relationship could evolve in an interesting way. Since they are in different time periods, they would face challenges that require both of their skills. Luffy's physical strength and Robin's intellectual prowess would complement each other. They might start to communicate more on an equal level, with Robin not just being a crewmate but more of a partner in their time - traveling escapades. Luffy would start to respect Robin's insights even more, and Robin would be more open with Luffy about her feelings and thoughts. This could lead to a relationship that is more intertwined and complex than it was before the time travel.
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.
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.
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.
In a time - travel scenario, their relationship might develop in a more equal way at first. Let's say they travel to a time when they both have to start from scratch. Luffy would rely more on Nami's intelligence for survival and planning, and Nami would see Luffy's leadership in a new light as they face new and unknown challenges together. As they work through these difficult times, they would grow closer and their relationship would be more complex, with a newfound respect for each other's abilities.
Their relationship could start with Uta being initially distrustful of Luffy. After all, Luffy is a pirate and Uta has her own ideas about pirates. But as she sees Luffy's pure heart and his determination to protect his friends and pursue his dreams, she starts to warm up to him. They might then become friends who share their different stories and experiences.
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.
In fanfiction, Robin and Luffy often share a unique bond. Luffy's carefree nature and Robin's mysterious side make for an interesting dynamic. Luffy's acceptance of Robin into the crew was a significant moment. Fanfic writers might explore how Robin, with her complex past, finds solace in Luffy's unwavering leadership and the Straw Hat crew's camaraderie.
In a fanfiction, their relationship might develop when Luffy gets injured and Hancock has to take care of him. This would be a new situation for Hancock as she is usually the one being protected. Luffy, in his injured state, would still be his positive self. Hancock would see his vulnerability and also his unwavering spirit. This could lead to a deeper emotional connection between them, with Hancock realizing she wants to be by his side not just because of her love for him, but also because she admires his character.
Their relationship could start off as a reluctant alliance. Klaus being Klaus, would probably try to use Bonnie for his own gains at first. But as they face different challenges during time travel, they might start to trust each other more. For example, if they are in a dangerous time period where both of their lives are at stake, they would have to rely on each other.
At first, their relationship might be filled with tension. Sesshomaru is a proud demon and Kagome is a modern - day girl. But as they travel through time and face challenges together, they start to respect each other more. Sesshomaru may see Kagome's courage and intelligence, while Kagome may understand Sesshomaru's complex nature better.
As they travel through time, they would rely on each other more and more. For instance, when they are in a dangerous situation in the past, Naruto would protect Shion with his life, and Shion would use her powers to help Naruto find solutions. This mutual dependence would deepen their relationship, turning it from just acquaintances to true friends or maybe even more.
