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.
One factor could be a new and extremely powerful jutsu. For instance, if Naruto creates a jutsu that combines the power of the Nine - Tails and Sage Mode in a way that Jiraiya can't defend against. Another could be an unexpected advantage like having insider knowledge about Jiraiya's weaknesses. Maybe he learned something from Tsunade that gives him an upper hand.
One 'naruto beat up' fanfiction could be about Naruto facing a powerful new enemy in a hidden village and having to fight his way out. Maybe he uses new jutsu combinations to beat up the bad guys.
Often, it's other powerful ninjas from rival villages. For example, shinobi from the Hidden Mist Village might be opponents. They could have unique abilities that Naruto has to overcome to beat them up.
It depends on the specific fanfiction. Some might have Naruto develop strategies or skills to overcome the paperwork challenge. Others might not focus on this aspect at all.
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.
