Some fanfics might put 10k in a different scenario, like he gets separated from the main group and has to survive on his own for a while. He might encounter a group of friendly survivors who have a completely different approach to survival than what he's used to. This could lead to some interesting character development as he adapts to their ways.
One great 10k z nation fanfiction could be about 10k's journey before he joined the main group. It might explore his early days surviving alone and how he developed his skills. Another could focus on a romantic relationship for 10k within the post - apocalyptic world of Z Nation. Maybe he meets a girl who also has a special ability and they team up to fight the zombies together.
One popular 'Naruto Z Nation Fanfic' might be those that combine the unique ninja world of Naruto with the post - apocalyptic setting of Z Nation in creative ways. For example, a story where Naruto characters have to survive in a Z Nation - like world filled with zombies. They could use their ninjutsu skills to fight off the undead. Another could be a crossover where the Z Nation survivors discover the power of chakra.
Survival is a very common theme. Given the post - apocalyptic setting of 'Z Nation', fanfics often revolve around 10k and other characters trying to stay alive among the zombies. They need to find food, shelter and avoid getting bitten.
Another idea for a fanfiction involving 10K in Z Nation is a time - travel scenario. What if 10K somehow got sent back in time to before the zombie outbreak? He could use his knowledge of the future to try and prevent the apocalypse, or at least change some things to make survival easier for everyone.
Well, 'Zombie Slaying Ninjas' is another great 'naruto x z nation fanfic'. It focuses on how the Naruto characters adapt to the new and dangerous world of Z Nation. For example, Sasuke uses his Sharingan to detect zombies from a distance, and they all work together to build a safe haven, which is very engaging.
Survival is a very common theme. Since it's set in the Z Nation world, characters like 10k are constantly fighting for their lives against zombies. Another theme is friendship, like the bond between 10k and his comrades. They rely on each other to get through tough situations.
In a fanfiction, 10K might get separated from his group. He then has to survive on his own in a very hostile environment filled with not only zombies but also other dangerous humans. During this time, he could learn new survival skills and also face some of his inner demons. He might even meet some new allies along the way who help him reunite with his group.
A fanfiction could explore 10k's backstory more in - depth. Maybe he had a family before the apocalypse that he is constantly reminded of during his travels. This could add a whole new emotional layer to his character.
Addy would also be a good choice. She is strong and resourceful. In a fanfiction, she and 10k could go on a mission to find a cure together. Their different personalities would create interesting dynamics as they face various obstacles along the way.
There could be many interesting scenarios in such a fanfiction. Maybe 10k, with his survival skills from Z Nation, ends up in the Twilight universe and meets Bella Swan. He could help her in a different way from the Cullens, perhaps using his combat skills against some new threats in Forks.
