In a time - travel fanfiction, Natsu's character might develop a sense of melancholy. If he travels to a time when Igneel was still alive but he couldn't interact with him directly (to avoid changing the past too much), it could make him long for his dragon father even more. This could fuel his determination to become stronger and protect the present and future. Wendy could develop a leadership side. If they end up in a time where there's chaos and no one to take charge, Wendy's kind heart and intelligence could lead her to start guiding people. She might use her healing magic not just to mend physical wounds but also to heal the rifts between different groups in that time.
For Natsu, time travel could make him more responsible. In a new time period, he'd have to be careful not to disrupt the timeline too much, which would be a big change for his impulsive nature. He might also gain a deeper respect for history and the importance of the past. For example, if he meets an ancestor of his, he'd start to see his family legacy in a new light. Wendy, on the other hand, could become more confident. She's often shy, but in a time - travel adventure, she'd have to step up and use her magic in new and challenging situations. This would force her out of her comfort zone and help her grow as a mage.
Natsu could develop a more strategic side. Usually, he just charges into battle, but in a time - travel scenario, he'd need to think about the consequences of his actions. He might study the enemies and allies in the new time period and come up with plans that are more calculated. This would be a significant evolution of his character. Wendy could develop a bolder personality. When faced with the unknowns of time travel, she could start taking risks that she wouldn't normally take. For instance, she might try out new combinations of her healing and support magic that she was too afraid to attempt before, and this experimentation could lead to her discovering new and powerful forms of her magic.
Natsu's character could develop by learning more about the history of magic and his own dragon - slayer powers. In a time - travel scenario, he might discover new ways to use his magic or even find out some secrets about his past that were long lost. This new knowledge would make him more powerful and also more mature as he realizes the importance of certain things in the grand scheme of things.
Sakura would likely become more self - reliant. In a time - travel scenario, she might not have the same support system she had in her original time. So she'd have to rely on her own skills and knowledge more. For Neji, he might start to question the strict beliefs he had in his clan. Seeing the past might make him realize how some of those beliefs were holding people back. He could become more of an advocate for change.
James would have the opportunity to see his parents and how they were in their youth. This could make him more appreciative of his family heritage and the values they held. He might also learn from his father's mistakes or heroic deeds. Lily, seeing the past, could be inspired to fight for equality and justice in the wizarding world even more. She could use the knowledge of the past to make changes in the present. Albus would be like a sponge, soaking up all the knowledge and experiences. He could form strong bonds with the people they meet in the past, which would influence his character development. His view of the world would expand, and he might come back to his own time with a new set of skills and a more developed moral compass.
Teddy, being a young character, would grow up very quickly in a time - travel story. He'd learn about the great sacrifices made by his family and the importance of loyalty. He could also develop new magical abilities by being exposed to different magical teachings from different eras. His character would transform from a somewhat naive young boy to a more mature and capable wizard, with a much broader view of the wizarding world.
When Harry and Teddy time travel, Harry could become more open - minded. He has been through a lot in his own time, but seeing different cultures and ways of life in other time periods would shatter some of his preconceived notions. Teddy would mature faster. Imagine traveling to a time of great turmoil in the wizarding world. Teddy would have to step up, make decisions, and face consequences. This would transform him from a somewhat carefree young wizard into a more responsible and strategic one. Harry, too, would learn from Teddy's growth and vice - versa, strengthening their bond and further developing their characters.
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.
Both of them would probably grow closer as they rely on each other in this strange new situation. They'd have to trust each other even more as they navigate through time. Their shared experiences in different time periods would give them a unique bond. They'd also have to adapt to different social norms and technologies in different times, which would force them to develop new skills and ways of thinking, and this would in turn shape their characters in different ways.
One great time travel fanfiction in the Fairy Tail universe could be 'Time's Twist'. In this story, Natsu and Wendy are sent back in time and have to figure out how to get back. It has really interesting character interactions, especially when they meet younger versions of their guild mates. They also have to deal with the threat that caused the time travel in the first place, which adds a lot of excitement to the plot.
One interesting plot could be that Natsu and Wendy travel back in time to the era when dragons were still abundant. They could learn powerful dragon - slaying magic directly from the dragons, which would not only enhance their powers but also give them a deeper understanding of their own abilities and the history of dragon slayers. This could lead to new friendships with the dragons and change the course of future events in their original timeline.
