Sasuke could also be a top pick. He's always looking for power and knowledge. In the FNAF world, he might see the animatronics as a source of new power or a mystery to unravel. His skills in combat and his Sharingan (if he has it in the crossover) would help him face any challenges. Plus, his brooding personality would add an interesting dynamic to the otherwise scary FNAF setting.
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.
Frisk could be a very interesting character to focus on. Frisk has the power of determination, which could be used in unique ways in the FNAF setting. They could befriend some of the animatronics, using their kindness and determination. Also, since Frisk is the player - controlled character in Undertale, it would be interesting to see how they adapt to the more dangerous and unpredictable world of FNAF.
Aphmau from MyStreet and Freddy Fazbear would be an interesting combination. Aphmau is a strong - willed leader in her world, and seeing her face off against Freddy, the iconic animatronic from FNAF, would be exciting. Another interesting pair could be Aaron from MyStreet and Foxy. Aaron is often protective, and Foxy has that unpredictable nature.
I think Freddy Fazbear and Toriel would make an interesting pairing. Freddy is this big, imposing animatronic, while Toriel is a motherly figure. Their interactions could be really cool, like Toriel trying to understand what Freddy is and Freddy being a bit confused by Toriel's kindness.
Frisk and Chica would also be a cool combination. Frisk is all about kindness and determination, and Chica is this animatronic with a bit of a goofy side. Frisk could try to understand Chica's motives and maybe even help her find a new purpose other than scaring people at night.
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.
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.
