There could be a scenario where a powerful entity from outside both of their universes pits them against each other as part of an experiment. Deadpool would be his usual self, trying to find loopholes in the rules of the fight. Naruto, on the other hand, would be determined to protect his world and friends from any potential threat. Maybe Deadpool and Naruto start off fighting but then realize they have a common enemy in this powerful entity and have to team up.
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 interesting scenario could be when Batman tries to analyze Naruto's chakra system using his detective skills. Another could be Naruto being teleported to Gotham and having to deal with Batman's villains while Batman tries to figure out who he is. And also, a scenario where they team up against a common enemy like an alien invasion in a crossover fanfiction world.
In some 'minato vs naruto fanfiction', there could be a scenario where they battle in a different dimension. Minato uses his Flying Raijin to quickly move around and Naruto counters with his shadow clones and massive Rasengan attacks. Also, a scenario where they fight not as enemies but in a friendly spar to teach Naruto some secret family jutsu that only Minato knew would be really cool.
One interesting scenario could be a fight in an alternate dimension where the rules of chakra are different. This would force both Naruto and Sasuke to adapt new strategies. Another could be a battle where they are forced to team up against a common enemy first before their duel, which would add a complex layer of emotions and dynamics.
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.
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.
One interesting scenario could be Naruto having to face multiple Akatsuki members alone and using new, unexpected jutsu. For example, he might combine his Rasengan with Sage Mode in a unique way to counter their attacks.
One interesting scenario could be a battle in a neutral dimension where Gohan's Saiyan powers and Naruto's ninja techniques are put to the test. Gohan's super strength and ability to go Super Saiyan might be pitted against Naruto's shadow clone jutsu and Rasengan.
Well, perhaps in the fanfic, Naruto is a big fan of Deadpool's comics in his own ninja world. One day, a mysterious jutsu goes wrong and he starts seeing Deadpool - like hallucinations. These hallucinations actually start teaching him new combat techniques and a different way of looking at life. As he follows these 'visions', he becomes more like Deadpool in his approach to battles and challenges in the ninja world.
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.
