Well, perhaps there's a plot where the World of Warcraft is in danger of being overrun by an evil force similar to the Otsutsuki in Naruto. The Naruto characters are called upon to help because of their unique abilities. Sakura could use her medical ninjutsu to heal the wounded in WoW, and Kakashi could lead strategic battles. The ninjas would have to adapt to the different terrains and cultures of WoW while using their own skills to turn the tide against the common enemy.
It could be really exciting. Maybe Naruto characters could be in the World of Warcraft universe, with Naruto using his ninja skills to fight against Warcraft creatures. For example, Naruto could use his Rasengan against a big ogre. And Sasuke might team up with a Night Elf to explore some ancient ruins.
One idea could be that Naruto characters are transported to the World of Warcraft universe. They could form alliances with different races like the Night Elves, with Naruto's ability to befriend others coming in handy. Another could be that the chakra system in Naruto somehow interacts with the magic in WoW, creating new and powerful spells.
Another concept is the crossover of different classes within Warcraft in fanfiction. For instance, a mage and a warrior might have to swap their traditional roles for a while. The mage has to use brute force, and the warrior has to rely on magic in a strange situation. This can lead to humorous and thought - provoking stories.
Well, one possible plot could be that Naruto and his friends are somehow transported to the Jurassic World. Naruto, with his ninja skills, would have to use his speed and agility to avoid the dinosaurs. Maybe he'd even try to befriend some of the less dangerous ones, like the herbivores. His shadow clone jutsu could be used to create distractions when they're being chased by a T - Rex or Velociraptors.
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.
