Kakashi could be an interesting addition too. His calm and collected demeanor, along with his vast knowledge and skills, would be very useful in the new and strange world of Kuroinu. He could serve as a mentor figure not only to the Naruto characters but also potentially to some of the Kuroinu characters who might be in need of guidance.
Definitely Naruto himself. He has such a dynamic personality. His never - give - up attitude and his ability to make friends easily would be really interesting in the context of the yokai world. He would be the one trying to bridge the gap between the two different groups, and his ninja skills would be a novelty among the yokai. Also, his encounter with the yokai would be a great opportunity to see how he adapts to a completely new type of opponent and power system.
Definitely Gaara. His ability to control sand is unique. In the Borderlands 2 setting, he could use his sand to protect his teammates from the various attacks, like from the psychos or the Loader Bots. His transformation into Shukaku could also be a very powerful and visually striking element in the crossover.
I think Gintoki would be the most interesting. His laid - back and cynical nature would contrast so much with the more idealistic Naruto. He would constantly be making sarcastic remarks about Naruto's ninja -isms and the whole concept of being a hero. But at the same time, he would also be secretly impressed by Naruto's unwavering determination. And seeing Gintoki try to use Naruto's ninja tools or techniques in his own wacky way would be really entertaining.
Naruto would be really interesting. His never - give - up attitude would make him stand out in the spooky FNAF world. He'd probably be the one to charge headfirst into danger, whether it's facing the creepy animatronics or trying to solve the mysteries of the place. He could also try to befriend the animatronics if he thought they were being controlled against their will, just like he did with some of his enemies in the Naruto world.
It could be Ben himself. Imagine him using his alien forms in the Naruto universe. His Heatblast form could be really useful against ice - based jutsu, and Four Arms could take on some of the physically strong ninja. He would bring a whole new element of power and chaos to the Naruto world, and his reactions to the different cultures and powers in Naruto's world would be interesting to explore.
Sasuke could be really engaging in this scenario. His cold and calculating nature would be a contrast to the chaos of the zombies. He might see the zombie outbreak as an opportunity to gain more power or find a way to use the situation to his advantage against his enemies in the Naruto world. And his Sharingan could potentially have some new abilities when dealing with the undead.
Sasuke could be a very interesting character in this crossover. He has his own dark and brooding nature. He might be more interested in the stronger and rarer Pokemon. His sharingan could give him an edge in understanding Pokemon's abilities and behaviors. He could also train Pokemon in a more intense and strict way compared to other trainers.
I think Naruto himself would be the most interesting. Just picture him with Hollow powers added to his already vast ninja skills. He's so full of energy and determination, and adding the element of Hollow abilities would take his character to a whole new level. He could use his newfound powers to protect his friends and the village in ways he never thought possible.
Definitely Naruto himself. He has such a strong personality and unique powers. In the Dishonored world, his ability to never give up and his positive attitude would be a fresh contrast to the often dark and brooding characters there. His ninjutsu skills would also make him a force to be reckoned with.
I think Rock Lee would be really interesting. His extreme dedication to training and his unique fighting style would be a great contrast to the often chaotic and self - serving characters in the GTA world. He could run around the GTA streets, challenging the thugs to combat and trying to uphold his ninja code in a very different and morally ambiguous environment.
