Who could be the most unexpected character to join Naruto's team in a 'Naruto Tournament of Power Fanfic'?

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.

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 could be an unexpected character to shine. He's often seen as more of a teacher figure, but in a fanfic, he could enter the Jounin exams. His knowledge of the students and his own ninja skills, which might be underestimated, could give him an edge. He could surprise everyone by using creative teaching - inspired tactics in the battles.

Maybe in the fanfic, the Tournament of Power is rigged from the start. Naruto's team realizes this early on. Their journey could be about finding evidence of the rigging while still competing. They might encounter traitors within their own ranks who are working for the ones behind the rigged tournament. Along the way, Naruto has to use his skills not only in battle but also in diplomacy to keep his team together.

It could be some of the younger ninjas from the village who look up to Naruto. Maybe a young genin who has a special ability with earth jutsu, and another who is really good at stealth but lacks confidence. Naruto would then help them grow.

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.

It could be a powerful rogue ninja who has organized the tournament for his own evil purposes. Maybe he wants to gather all the strong ninjas in one place to defeat them and prove his superiority.

Well, it could be about Naruto entering a secret and dark tournament where the rules are brutal. Maybe he has to fight against powerful foes he's never encountered before, like some rogue ninjas with new and dangerous jutsus. And there could be some mystery behind the tournament, like who's really organizing it and what their end goal is.

Howard the Duck. It would be really unexpected. He could bring some comical relief but also have some hidden knowledge about the disks that could be crucial. For instance, he might know of a weakness in a powerful enemy's disk - based powers.

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.
