Who would be an unexpected but great addition to a 'tournament of power fanfiction'?

Well, perhaps a character from a very low - key anime that no one expects. Like a character from a slice - of - life anime who has some hidden power. Maybe a schoolgirl who can control time in short bursts, but has been keeping it a secret in her normal life.

Genos could be an unexpected opponent. He might be forced to fight Saitama due to some mind - control or a misunderstanding in the rules of the tournament. It would be really interesting to see how Saitama would handle fighting his own disciple, and how Genos would fare against his master's incredible strength.

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.

Puar could be an interesting underdog. Although not typically a fighter, in a fanfiction, Puar could have some hidden power or develop a new technique. Maybe Puar could transform into a super - powerful creature with unique abilities that catch everyone off - guard in the Tournament of Power.

I think Broly could also be a really tough opponent. In his Legendary Super Saiyan form, he has incredible power and his rage - driven fighting style could give Goku SSJ4 a hard time in the Tournament of Power. Broly doesn't hold back and his raw power could potentially overpower Goku if he's not careful.

Filch could be an unexpected character. He might enter the tournament in a comical way, like he accidentally stumbles into the selection process and ends up being a participant. Another could be Peeves. He could disrupt the tournament in his usual mischievous way, or perhaps he is made a part of a task where the competitors have to outwit him.

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.

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 Naruto were in the Tournament of Power in fanfiction, it would be amazing. His ninjutsu skills would be a spectacle. He might start off by using his basic but effective jutsus to assess his opponents. As the tournament progresses, he could tap into his Sage Mode or even the power of the Nine - Tails more deeply. His interactions with other universes' fighters would be interesting, like how he would deal with the different fighting styles and powers that he has never encountered before. He might also face some moral dilemmas during the tournament, such as whether to help an opponent in danger or focus solely on winning.

Orochimaru. Despite his past as a villain, he could have some knowledge or power that Naruto needs in the tournament. Maybe he has some ancient jutsu that can counter the abilities of opponents from other dimensions. His presence would also add a lot of tension within the team as some members would be very suspicious of him.
