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.
Itachi would also be a fascinating character in this type of crossover. His calm and calculating nature would be an interesting contrast to the chaotic nature of Hollow powers. He could potentially use the powers in very strategic ways to protect his secrets or to achieve his goals. Also, his relationship with Sasuke could be further complicated by the introduction of these new powers and the implications they have for the Uchiha clan.
I think Naruto himself would be very interesting. His energetic and fearless personality would contrast greatly with the spooky atmosphere of Sleepy Hollow. He would likely approach the strange happenings in Sleepy Hollow with his usual enthusiasm and determination to overcome any challenges.
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.
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.
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.
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.
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 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.
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.
Definitely Brennan and Crane. Their different worldviews would create a great dynamic. Brennan is all about facts and science, while Crane is from a time where superstition was a big part of life and he has first - hand experience with the supernatural. Their interactions would be full of tension and learning opportunities for both characters. For instance, Brennan could try to explain the Horseman's existence through scientific means, while Crane would be trying to get her to accept that some things are beyond science.
I think Naruto would be the most interesting. His out - of - place ninja skills and his positive attitude would create a lot of chaos and also some really heartwarming moments in the Bebop universe.
