The cat could have the ability to turn invisible. This would be really useful in spying on enemies or sneaking into dangerous places. Naruto could use this to his advantage during missions.
They could team up to rescue a kidnapped ninja. The cat could track the kidnapper's scent, and Naruto could engage in combat when they find the enemy. Naruto's determination combined with the cat's stealth would make them a formidable duo in this rescue mission.
The cat could make Naruto more approachable. His friends might be drawn to the cat and start spending more time with Naruto because of it. For example, Sakura might see Naruto's kindness towards the cat and start to view him in a new light, strengthening their friendship.
Well, it could be about Naruto finding a stray cat on one of his missions. The cat might have some special abilities, like being able to sense chakra. Naruto takes the cat in and they form a bond. The cat could then accompany Naruto on his adventures, helping him out in unexpected ways during battles, like distracting the enemy with its cuteness or using its special chakra - sensing ability to detect hidden traps.
A common theme could be friendship. Just like Naruto's relationships with his human friends, his bond with the nin cat could be about loyalty and mutual support.
One interesting masked ninja is Shinji. He is a masked character in fanfiction who was once a normal ninja but got cursed by an ancient evil. Now, with his masked identity, he tries to find a way to break the curse while also using his new - found dark powers for good in the Naruto world. There's also a masked ninja named Yuki. Yuki is a snow - style user and her mask is made of ice crystals. She is on a quest to find the origin of her ice - based powers. Another is Hikaru, a masked ninja with the power of light, who is often at odds with the darker elements in the Naruto fanfiction world.
Well, if Naruto had cybernetics in fanfiction, his physical strength could be enhanced. For example, his punches and kicks might carry more force, allowing him to take on stronger opponents more easily. His speed could also be increased, making it harder for enemies to track him. Maybe the cybernetics could also enhance his chakra control in some way, like allowing him to more precisely direct his chakra for jutsu, which would make his Rasengan even more powerful.
The cat could have the ability to sense chakra. Just like how some animals in the Naruto world can detect danger or the presence of others through their natural instincts, Naruto's cat might be able to sense chakra levels, which could be helpful to Naruto in various situations.
A possible plot for this type of fanfiction could involve the banished ninja having a secret mission that the village doesn't want to be associated with. So, they banish the ninja to make it seem like they have no part in it. The ninja then has to complete the mission while also dealing with the stigma of being banished.
