It could be. It depends on the specific plot and characters involved. If there are elements from different zombie-related universes combined, then yes.
One possible plot could be that a powerful necromancer from the Naruto world accidentally unleashes a zombie plague. Naruto and his friends have to not only fight their zombified comrades but also find a way to reverse the spell. They could use their ninja skills in unique ways, like using shadow clones to distract the zombies while they search for a cure.
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.
Well, perhaps in the fanfiction, the SAS discovers a portal that leads to a different dimension full of zombie - like creatures but with unique abilities. They then have to use their military skills combined with the knowledge they gain from the new environment to survive and close the portal. They could encounter some local resistance fighters in that dimension who are also trying to fight the zombies, and they all join forces.
How about including some characters from the Left 4 Dead series? The survivors in that game have a lot of experience fighting zombies in different environments. They could work together with the SAS in the crossover fanfiction. For example, Zoey could use her street - smart skills, and Louis could contribute his knowledge of finding supplies in urban areas. And of course, the Special Infected from Left 4 Dead could add more danger and variety to the zombie threats in the story.
There might be. A lot of fanfiction writers like to explore unique and interesting concepts like a godlike Naruto in a zombie - filled world. However, the quality can vary greatly. Some might be really well - written with complex storylines and character development, while others could be more on the amateur side. You have to dig through to find the good ones.
Superman from the DC universe. Superman stands for truth, justice, and the American way, but his methods are often more lenient compared to Akainu. The two could have a philosophical debate about justice while also having to fight a common enemy.
One idea could be a crossover with the X - Men. Spider - Man could team up with Wolverine. Their different fighting styles would make for some amazing action scenes. Wolverine's brute strength and healing factor combined with Spider - Man's agility and web - slinging abilities would be a great combination.
A crossover with Captain America could be great too. Spider - Man, with his youth and modern - day sensibilities, could learn a lot from Cap's old - fashioned values. They could fight side by side against Hydra agents or other villains, and Spider - Man could show Cap some new tricks when it comes to acrobatics in combat.
