Orochimaru could also be a character to beat up Naruto in a fanfic. He's always been interested in the power of the Nine - Tails and Naruto as a whole. He might see an opportunity to capture Naruto and in the process, end up beating him up to subdue him.
Sasuke could be one. Given their complex relationship, there could be a situation where Sasuke's newfound power or different ideology leads him to fight and beat Naruto in a fan - made story.
I think it's a toss-up. Deku has potential and is constantly evolving, but Naruto's strength and strategic thinking give him an edge. It could come down to the specific circumstances of the fight.
Definitely, the incident needs to be reported to the authorities. The teacher should be held accountable legally. And the school should review its policies and training to prevent such incidents in the future. The well-being of the student must be the top priority.
In a 'Naruto Needs Help' fanfiction, Naruto could get help from unexpected sources. The tailed beasts themselves could come to his aid. Since Naruto has a connection with Kurama, the other tailed beasts might sense his distress and offer their power. Also, characters from other villages. For example, Killer Bee could teach Naruto some new techniques related to the tailed beasts' power, or Temari could use her wind techniques to assist in a battle where Naruto is outnumbered.
Their werewolf forms could also bring them closer to some characters. If there are other werewolf - like creatures in the fanfiction, they would form a new bond. For instance, if there's an old werewolf hermit in the forest near the village, Naruto and Kiba could seek him out for advice on controlling their powers. This new relationship could help them better understand their werewolf sides and also teach them new ninja techniques related to their werewolf abilities.
In Naruto forms a mercenary fanfiction, a frequent theme is Naruto's isolation. When he becomes a mercenary, he often finds himself outside the normal ninja social structure. He has to make new friends and allies in a more cut - throat world. Also, the idea of redemption is common. Sometimes Naruto is trying to atone for past mistakes or the actions of the Hidden Leaf by working as a mercenary. He may use his new role to help those who have been wronged by the ninja system. Moreover, there's the exploration of power dynamics. As a mercenary, Naruto has to negotiate his power and services, which is different from his role as a ninja in the village.
One form is the love for family. In some fanfictions, a child character might be on a quest to find their long - lost family, driven by the love they have for them even without ever having met them. Another form is the love for justice. A child could be inspired by the stories of the great ninjas before them and develop a love for upholding justice in the ninja world.
I think Rock Lee could be part of the group. His unwavering determination and powerful taijutsu skills would be valuable. Neji, with his Byakugan and strong combat abilities, would also fit in well. And Tenten, with her expertise in weaponry, could bring a different kind of combat strength to the group. They all have different skills that would complement each other in Naruto's formed group.
