Kakashi shows a variety of new jutsu in the manga. One notable one is a lightning-based technique that enhances his offensive capabilities.
Kakashi, as the Hokage, presents a new space-time jutsu in the manga. This jutsu allows him to manipulate the battlefield and surprise his opponents with unexpected movements.
Yes, Kakashi does become Hokage in the manga.
Yes, he does. At a certain point in the manga, Kakashi reveals his face.
Well, it could be that the Sexy Jutsu has some sort of psychological effect on the Third Hokage. Maybe it reminds him of someone or something from his past that makes him hesitate. And in that moment of hesitation, Naruto is able to use the distraction to his advantage and defeat the Third Hokage. Also, Naruto might be able to use the jutsu in combination with other moves in the fanfiction. For instance, while the Third Hokage is distracted by the Sexy Jutsu, Naruto quickly follows up with a Rasengan.
One common theme is redemption. Since Kakashi can go back in time, he often tries to make up for past mistakes or prevent tragedies that occurred in the original timeline. For example, he might try to save a character who died before. Another theme is the changing of fates. He can change the destiny of not only himself but also of his friends and the whole village. He can use his knowledge of future events to better prepare for threats.
He could create a jutsu that allows him to teleport short distances. Given his quick thinking and need for mobility in battles, a short - range teleportation jutsu would be very useful. It could be like a mini - version of Kamui but powered by his own chakra.
Emotionally, it would be a powerful encounter. They might share their feelings about the losses they've all faced, like the death of Minato. This could strengthen their relationships and also give Kakashi new insights as Hokage on how to protect the village better.
One possibility is that there would be a lot of reminiscing. Team Minato was Kakashi's old team. They might talk about old missions, like the one where they faced the Stone ninjas. Kakashi could share how their teachings influenced his leadership as Hokage.
Kakashi's jutsu like the Chidori, which is a powerful lightning - based attack, might interact strangely with the magic in the Harry Potter world. For example, it could disrupt spells if used in close proximity. On the other hand, Harry's magic could potentially be used to enhance Kakashi's jutsu, like using a spell to increase the speed or power of the Chidori.
A cool plot would be Kakashi traveling back to a time during one of the great ninja wars, say the Third Great Ninja War. He could use his knowledge of future jutsu and strategies to turn the tides of battles that were previously lost. He might also be able to save comrades who died in the original timeline, and in the process, change the future of many ninja families.
One great Kakashi Hokage time travel fanfiction is 'Kakashi's Time - Travel Redemption'. In this fic, Kakashi goes back in time and uses his knowledge to prevent some of the tragedies that happened in the original timeline. He focuses on training the younger generation earlier and making strategic changes. It's a really interesting read as it shows a different side of Kakashi's leadership and how he could have changed the course of the Naruto world if given the chance to go back.
