In a fanfiction battle, perhaps the fight begins with Naruto trying to talk to Goku first, to understand his intentions. Goku, not really understanding Naruto's world, just wants to test his strength. So he attacks without warning. Naruto quickly enters his Nine - Tails Chakra Mode to defend himself. The fight then escalates as Goku powers up further. The two exchange blows, with Goku's punches creating shockwaves and Naruto's attacks leaving marks on the ground. As the fight goes on, they both start to respect each other's power and skills, and it becomes more of a battle of wits as well as strength.
One scenario could be that Naruto uses his shadow clone jutsu to overwhelm Superman. The clones could attack from all directions, and while Superman is busy dealing with them, Naruto could prepare a powerful Rasengan. Another scenario might be Superman using his heat vision to try and stop Naruto's summons, like the giant toads. But Naruto could use his speed and agility to dodge and counter - attack.
One possible storyline could be that Naruto is somehow transported to Goku Black's universe. There, he has to face Goku Black who sees him as an intruder. Naruto would have to quickly learn about Goku Black's powers and find a way to fight back using his ninja skills. Another storyline could be that a powerful villain creates a rift between their two universes and pits them against each other. They start off as enemies but then realize they are being manipulated and team up to fight the real villain.
One scenario could be that Naruto underestimates Kiba at first. Kiba and Akamaru launch a surprise attack using their Fang over Fang technique. Naruto is caught off guard but quickly recovers and creates a wall of shadow clones. Another scenario is that Kiba challenges Naruto in a more strategic battle, like in a forest where he can use the environment to his advantage. Naruto, on the other hand, uses his Sage Mode to sense their movements and counterattacks with his Rasengan.
Another scenario could be that Naruto and Sasuke discover a new power within themselves during the fight against Kaguya. This new power could be related to their friendship or their connection to the Sage of Six Paths. They then use this power to finally defeat Kaguya.
Another scenario could involve Minato teaching Naruto some new jutsu. Since Minato was a very powerful ninja, he could pass on some of his secret techniques to Naruto. This would not only strengthen Naruto further but also be a great bonding moment between father and son. They could also talk about the past, like how Minato sacrificed himself for the village and Naruto could share his own struggles growing up without his father.
Perhaps in the fanfiction, Naruto is betrayed during the battle. By someone he trusted, like a comrade who was secretly working for the enemy. This betrayal catches him off - guard, and he is severely injured. Unable to fully recover, he succumbs to his wounds during the fight.
In a fanfic, there could be a scenario where Naruto and Superman start off as enemies but then realize they have a common enemy. They then team up against this new threat. During their initial fight, Superman might underestimate Naruto's speed and agility, which are enhanced by his ninja training. Naruto, on the other hand, might be initially shocked by Superman's sheer power. But as the fight progresses, they could come to respect each other's abilities and decide to work together.
One scenario could be Naruto using his clones to distract the Justice League while he sneaks up on Superman and uses a powerful jutsu. Another could be the Justice League trying to find Naruto's weakness, like his connection to the nine - tailed fox, and Naruto having to defend himself against their attacks. Maybe Batman tries to analyze Naruto's fighting style and come up with a plan to defeat him.
In some fanfictions, Naruto might face unique challenges right after becoming Hokage. For example, he could have to deal with a new, powerful enemy that targets the village because of his new position.
In some 'goku gets hurt fanfiction', he might get hurt while protecting his friends or family. For example, he could take a fatal blow meant for someone else. This would not only physically harm him but also add an emotional aspect to the story as his loved ones would be worried and try to save him.
