Well, Naruto and Madara's combined abilities are quite diverse. Naruto has his unique Uzumaki vitality and his ability to connect with others on an emotional level, while Madara has his centuries - old knowledge and experience. When they time travel, this fusion could introduce new concepts to the ninja world. Their combined Sharingan and Sage Mode abilities could be used to sense and predict threats on a much larger scale. They might also use their powers to unite different ninja clans that were previously at odds, as Naruto would promote peace and Madara's power would enforce it, changing the very fabric of the society in the time they visit.
The combination of Naruto and Madara's abilities would bring about a significant shift in the power balance of the world they time travel to. Naruto's positive influence and ability to inspire others, combined with Madara's strategic mind and combat skills, could lead to a new era of peace and cooperation. Their combined ninjutsu could also revolutionize the way ninjas in that time train and fight. For instance, Naruto's Rasengan combined with Madara's fire - based jutsu could create a whole new type of attack that others would try to emulate.
Their combined abilities would likely make them the most powerful entity in the ninja world. For example, Naruto's ability to sense negative emotions and Madara's combat experience could lead to a new form of justice. They could easily defeat any rogue ninja or group that threatens the peace.
Naruto would probably get Madara's Sharingan abilities. This could give him enhanced perception and the ability to copy jutsu more easily, like a supercharged version of his own ability. He might also gain access to Madara's Susanoo, which would be a huge boost to his combat capabilities.
Orochimaru's experiments and his knowledge of forbidden jutsu would be far ahead of the time he travels back to. He could use this to his advantage, perhaps by creating new techniques based on the limited knowledge of the past. However, he also has to be careful not to change the future too much as his actions in the past could have unforeseen consequences for his future self.
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.
Also, in the past, they might have to adapt their fighting styles. Naruto, used to fighting with his friends and allies from his own time, now has to work with different ninja in the past. He may have to learn new teamwork strategies and combine his abilities with those of the past - time ninja in a different way. Tsunade might also have to rely more on her brute strength and less on her developed medical and strategic skills from the future, at least until she can adjust to the past situation.
When the Konoha 12 time - travel to the past, their abilities would change significantly. Take Rock Lee for example. In the past, there might be different training methods that could further boost his physical strength and taijutsu skills. He could learn from the masters of old and bring back new techniques. For Ino, her mind - transfer jutsu might work differently in the past due to the different mental states and chakra signatures of the people then. And for Shikamaru, his strategic thinking would have to adapt to the different political and combat situations of the past. Their abilities would not only change in terms of power but also in how they are applied in the context of the past's ninja world.
In some stories, like 'A New Dawn', Madara uses his knowledge of future jutsus to teach the younger generation earlier. This gives the ninja world an edge in battles and changes the power dynamics. For example, he might teach some advanced fire - style jutsus to the Uchiha clan members much earlier than in the original timeline.
Well, perhaps they travel back in time to the era when the ninja clans were first forming. Their fused presence could disrupt the power balance among the clans. The fused entity might try to introduce new ninja techniques or ways of thinking based on what Naruto and Madara know from their respective times. They could also encounter their own ancestors and have to deal with the moral dilemma of interfering with their family lines. Maybe they end up influencing the creation of certain ninja villages in ways that are different from the original history.
In a time travel situation, they would be forced to rely on each other. Naruto's positive attitude and Fem Madara's power would complement each other. They might start as reluctant allies but gradually develop a deep bond. Maybe they'd have moments where they save each other's lives in the past, which would further strengthen their relationship. They could end up being a powerful duo that changes the course of ninja history together.
In a time travel fanfiction, Naruto's ability to sense danger might be sharper as he knows the big events that are supposed to happen. He could also train his Rasengan in new ways based on his future experiences. Sakura might be able to use her strength in a more controlled manner, having seen the consequences of over - using or under - using it in the future. Shikamaru could have an edge in planning battles because he's aware of different fighting styles from the future. Choji could find new ways to boost his strength using the knowledge he has of future food combinations that enhance chakra. And Ino could use her mind - transfer jutsu more precisely, having learned from future mistakes.
