I think Naruto himself would be the most interesting. His boisterous personality and strong will would make him stand out in the world of The Dragon Prince. He could bring his positive attitude and his never - give - up spirit to inspire the characters there. Also, his ability to make friends easily could lead to some really heartwarming friendships with the likes of Callum or Ezran.
Sakura would be a very interesting character to cross over. In Naruto, she has grown from a somewhat weak character to a very strong kunoichi. In The Dragon Prince, she could use her medical skills, which are quite advanced, to help the wounded in the ongoing wars. And her temper and strong - willed nature would make her interactions with the more stubborn characters in The Dragon Prince really fun to write about. She could also learn about the magic there and maybe incorporate it into her own fighting style.
One idea could be a crossover where Naruto's ability to use chakra is combined with the magic in The Dragon Prince. For example, Naruto could teach some of the characters in The Dragon Prince how to better control their magic by using chakra - control techniques. Another idea is that a character from Naruto somehow ends up in the world of The Dragon Prince and has to adapt to the new environment and its rules. Maybe Sasuke could be the one who gets teleported there, and he has to use his Sharingan in new and unexpected ways to survive.
Rayla and Aang from Avatar: The Last Airbender would be an interesting crossover. Rayla's skills as an assassin and Aang's airbending and pacifist nature could create some really cool interactions. They both have a strong sense of justice, but approach it in different ways.
I think Dom Santiago from Gears of War would be really interesting. He has that strong sense of loyalty and his combat skills are top - notch. In the Naruto universe, he could bond with characters like Shikamaru over their strategic thinking. He could also teach the Naruto characters some of the Gears of War combat tactics, and in return, learn about chakra and ninja techniques.
I think Naruto himself. His never - give - up attitude and his ability to make friends easily would make for great interactions in FF14. He could inspire the other players or characters in the game to be more brave and determined.
Twilight Sparkle from MLP would be an amazing crossover character into the Naruto world. She is intelligent and curious, just like many of the ninja in Naruto. She would be fascinated by the concept of chakra and would likely try to study it. Her magic skills could also be compared and contrasted with ninjutsu, making for some really cool interactions.
Naruto himself would be very interesting. His never - give - up attitude and powerful jutsu would make him a great addition to the AOT world. He could inspire the people there to keep fighting against the Titans. His ability to make friends easily might also help in uniting different groups in the AOT world.
Goku from Dragon Ball (just kidding, not part of Naruto or Pokemon but for a fun comparison). Seriously, Kakashi would be great. His laid - back but highly skilled nature could make for some interesting interactions. He might have a team of unique and rare Pokemon that he's collected over the years. And his experience as a ninja teacher could also come in handy when training Pokemon. He could teach them ninja - like stealth and combat maneuvers.
One idea could be that Naruto is somehow transported to the world of The Dragon Prince. He might use his ninja skills to help the characters in their quest. For example, his shadow clone jutsu could be used to deceive enemies or perform multiple tasks at once during a battle against the forces of evil in The Dragon Prince's world.
Sasuke would be really interesting. His brooding nature and powerful ninja abilities would create a great contrast in the Heaven's Feel world. He could be seen as a rival to some of the Servants or form an uneasy alliance with them.
I think Naruto himself would be really interesting. His never - give - up attitude and his powerful jutsu like the Rasengan would make him a force to be reckoned with in the Asterisk War world. He could inspire the characters there with his talk of friendship and protecting what's important.
