Perhaps in this fanfiction, Venom is a result of some dark jutsu experiment gone wrong in the Naruto universe. Naruto discovers Venom and realizes that he can control it with his own willpower. Together, they journey to find out who created Venom and stop them from creating more dangerous symbiotes. Along the way, Naruto teaches Venom about friendship and loyalty, which are concepts foreign to the symbiote at first.
Well, a cool plot might be that Venom's symbiote bonds with Naruto. Naruto then has to deal with the newfound power and the aggressive nature of the symbiote. He could use the enhanced strength and abilities to take on stronger foes in the ninja world. And the other ninjas would be both in awe and a bit scared of this new Naruto. For example, when facing Pain, Naruto with the Venom symbiote could have a very different and more brutal fight style.
One possible plot could be that Venom somehow gets transported to the Naruto universe. He might initially be seen as a strange and powerful beast. Naruto, being the curious and friendly ninja he is, tries to communicate with Venom. They could end up teaming up against a common enemy like Orochimaru who is interested in Venom's powers for his own dark experiments.
Well, one possibility could be that Venom, being an anti - hero, is initially seen as a threat by the Avengers. But then they realize that there's a greater enemy that they both need to face. Maybe an alien force that is immune to the Avengers' usual attacks but Venom's symbiotic abilities can somehow counter. So, they reluctantly team up, with Venom constantly trying to assert his own way of doing things, leading to some interesting clashes and character development within the team - up.
Well, it could be that Venom somehow gets transported to the Star Wars universe. Maybe he lands on a planet like Tatooine and causes chaos among the local gangs. The Sith could be interested in his power and try to control him, but Venom is too wild. And the Jedi might sense his dark presence and have to decide whether to destroy him or try to redeem him.
Definitely Naruto. His positive attitude and strong will could create a really interesting dynamic with Venom. He could either try to reform Venom or use its power for good in the Naruto world.
Well, perhaps in this fanfiction, the SAO system is corrupted by an Orochimaru - like figure. He wants to use the virtual world to gain power and immortality. Naruto and his friends, along with the SAO players, have to team up. Naruto's positive attitude and never - give - up spirit inspire the SAO players. They all work together to defeat this new threat, with Naruto using his Rasengan in new and creative ways within the SAO world.
A plot could involve the Killzone characters getting access to chakra. Some of the Killzone soldiers might start to learn ninjutsu and this causes chaos in their own military structure. Meanwhile, Naruto has to figure out how to get back to his own world while also dealing with the new threats that this crossover has created. Maybe he teams up with some of the more honorable Killzone soldiers to find a solution.
A plot might involve Naruto being sent to Bayonetta's world. He'd be out of his element, but his determination would shine through. Bayonetta could mistake him for a strange demon at first. However, they soon realize they can help each other. Naruto's chakra could interact in unexpected ways with Bayonetta's magic. Together, they could face off against Bayonetta's foes, like the angels, with Naruto's Rasengan combined with Bayonetta's Witch Time abilities making for some epic battles.
In a Naruto and Spiderman crossover, it could start with Spiderman noticing some strange energy signatures in his city. These turn out to be Naruto's chakra flares. Naruto is there looking for a way back to his own world after being accidentally sent to Earth - 616 (the Marvel Universe). They meet and at first don't understand each other. However, when they see a common enemy, a group of ninjas - like mutants who are causing chaos, they decide to work together. Spiderman uses his agility and web - shooting while Naruto uses his jutsu to defeat the bad guys.
One possible plot could be that Naruto and his team are on a mission in a strange new land that turns out to be the world of Claymore. They encounter Claymores, the half - human, half - yoma warriors. Naruto, with his never - give - up attitude, tries to understand the complex relationship between humans and yoma in this world. He could end up befriending some of the Claymores and together they fight against a powerful common enemy that threatens both their worlds.
One possible plot could be that Naruto, while on a mission, somehow gets transported to the world of Undertale. He teams up with Frisk to stop Flowey from taking over both their worlds. Naruto's ninja skills, like his shadow clones, could be used in creative ways in the battles against the monsters in Undertale.
One possible plot could be that Guts from Berserk is somehow transported to the Naruto universe. He might initially be seen as a threat due to his menacing appearance and his large sword. However, as the story progresses, he could team up with Naruto and his friends to fight against a common enemy, like an Akatsuki member who has acquired some of the dark magic from the Berserk world. Guts' fighting skills and his ability to face the most terrifying foes could inspire Naruto and give him new perspectives on combat.
