A great plot could involve the resurrection of past powerful ninja to participate in the Tournament of Power. Imagine if the likes of Hashirama and Madara were brought back. Naruto and his allies would have to face not only the current threats but also these legendary ninja. There would be a lot of drama as Naruto tries to understand their motives and also figure out how to defeat them without causing too much destruction.
If Broly joined the Tournament of Power, it would be an absolute game - changer. His raw power is off the charts. He could easily take on multiple opponents at once. He might start by targeting the strongest foes, like Jiren. His uncontrollable rage could work in his favor, as opponents would be intimidated. However, his lack of teamwork skills could also be a drawback. But with his power, he could probably just brute - force his way through many battles.
Iruka. He's mostly seen as a teacher and not a combat - heavy character. But in fanfiction, he could be given some hidden powers or a special training arc before the tournament. His inclusion would be unexpected because everyone underestimates him, but he could use his knowledge of Naruto and the other ninja to come up with unique strategies in the tournament.
If Broly was in the Tournament of Power, it would have a huge impact on the outcome. His power is extraordinary. He could change the strategies of all the teams. For example, Universe 11 might focus all their efforts on taking Broly out first. This would create openings for other Universe 7 fighters. Also, Broly's berserker - like fighting style could disrupt the order of the battles. He might accidentally destroy parts of the arena, affecting the fighting conditions for everyone. In the end, his presence would make the tournament much more unpredictable and exciting.
In some fanfictions, Goku Black has been depicted as having a hidden power reserve. In the Tournament of Power, he could tap into this reserve and achieve a new level of transformation. This new form would give him increased speed, strength, and energy projection. He might use this form to take on multiple strong opponents at once, like the powerful warriors from Universe 7 or other universes. His attacks could become more unpredictable, such as his energy beams changing direction mid - flight to catch his foes off - guard.
Captain Jack Sparrow from the Pirates of the Caribbean world. Imagine him being thrown into the Tournament of Power. His wily and unpredictable nature, along with his knack for getting out of tough situations, would make for some really interesting interactions with the more serious combatants in the tournament. He could use his cunning to outwit opponents rather than relying on pure strength.
A plot could revolve around a team-up that no one expected. Like a villain and a hero from different universes having to work together in the Tournament of Power. They start off distrusting each other but gradually learn to respect and rely on one another. This could add a whole new layer of drama and character development to the fanfiction.
Maybe in the fanfiction, the Tournament of Power rules are changed specifically for Saitama. Instead of just fighting, he has to complete various challenges like making his opponents laugh before knocking them out. This would add a humorous twist to the story as Saitama tries to come up with different ways to make his opponents crack up, all while still being his super - strong self.
A plot twist could also involve Broly being transported to a different dimension during the tournament. In this new dimension, he has to face off against versions of his enemies that are much stronger or have different abilities. He would then have to find a way to return to the Tournament of Power while also dealing with these new threats.
