Definitely Naruto and Link. Naruto's energetic and determined personality would contrast well with Link's more stoic nature. They could learn a lot from each other. Also, Zelda would be interesting. Her wisdom and magical abilities would add a different dimension. And Sasuke could also be a great character to include. His dark past and thirst for power could lead to some interesting interactions in the Zelda world, especially when faced with the power of the Triforce.
In a Naruto Zelda crossover fanfiction, the Sages from Zelda and the Kage from Naruto could be really interesting to explore. The Sages' connection to the land and their magic, compared to the Kage's leadership and ninja powers. For example, the Fire Sage and the Hokage could exchange knowledge about fire - related powers. And then there are the side characters like Tails from Zelda and Rock Lee from Naruto. Rock Lee's determination and unique fighting style could be really cool when paired with Tails' acrobatic skills and his ability to glide around.
Definitely Naruto and Geralt. Naruto with his bright - eyed optimism and powerful ninja skills would contrast greatly with Geralt's brooding and more practical monster - hunting skills. Their interactions would be full of learning and cultural clashes. For example, Naruto might be shocked at how Geralt deals with certain 'monsters' that in Naruto's world could potentially be redeemed. And Geralt would be intrigued by Naruto's chakra and jutsu.
Definitely Naruto and the main Guyver character. Naruto because of his determination and growth throughout the Naruto series. He would be really interesting to see how he adapts to the Guyver's powers. And the Guyver, because its powers are so unique and different from the ninja abilities in Naruto. Their interactions could be full of misunderstandings at first as they come from different worlds, but then they could learn from each other.
I think Naruto and Daredevil are the obvious main focuses. But also, Elektra from Daredevil's world could be a great addition. She could have some sort of connection to a female ninja in the Naruto universe, like Sakura. Sakura could learn a thing or two from Elektra's combat style, and Elektra could be intrigued by Sakura's medical ninjutsu. And then there's also Itachi. His complex backstory and powerful abilities would make for a great interaction with Daredevil, especially considering Daredevil's sense of morality and Itachi's own moral dilemmas.
For me, it would be the Nine - Tails from Naruto. Imagining how the giant, powerful fox would be perceived in the Destiny universe, where there are all kinds of strange and powerful creatures, would be really cool. And from Destiny, the Exo Stranger. Her mysterious nature and time - traveling abilities could add a lot of intrigue to the crossover. Another interesting character to focus on could be Sakura. Her growth as a medical ninja and her combat skills could be useful in the Destiny setting, and her relationship with Naruto and Sasuke could bring in some interesting character dynamics.
I think Naruto and Green Lantern Kyle Rayner would be great to focus on. Kyle is known for his creativity with the ring, and Naruto is full of creative combat ideas. They could learn from each other. Also, Sasuke could be an interesting character. His dark past and his thirst for power could be a contrast to the more noble Green Lanterns. Maybe he could be tempted by the power of the Green Lantern ring in a different way than Naruto.
For sure Naruto himself would be interesting. His determination and never - give - up attitude could be a great contrast to the more structured and sometimes rule - bound Green Lanterns. Also, someone like Hal Jordan from the Green Lantern side. His cocky and confident nature could lead to some interesting interactions with Naruto.
I think Naruto himself would be really interesting. His positive attitude and strong will would contrast greatly with the cynical world of The Boys.
I think Alex Mercer would be really interesting. He has such unique and powerful abilities in the Prototype world. In a crossover with Naruto, seeing how he would interact with the ninja and their chakra - based powers would be fascinating. He could either be an ally or a potential threat depending on how the story unfolds.
I think Naruto himself would be very interesting. His never - give - up attitude and his powerful jutsu would make for great interactions in the Titanfall universe. He could befriend Pilots and learn about their technology while also showing them the power of ninja skills.
Naruto himself would be very interesting. He already has a strong will and a desire to become stronger. Adding Saiyan powers to his arsenal would make for a great story. We could see how he adapts to having a tail, the new transformation abilities, and how his friends react to his new look and powers.
