One possible plotline could be that Addy somehow gets transported to the Naruto world. Maybe she has to learn about chakra and ninjutsu while also using her skills from Z Nation to survive in this new and strange place.
I'm not sure specifically which 'Naruto x Z Nation Naruto x Addy' fanfictions are the best. You could try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of fan - created stories, and you can use the search function to look for ones related to this specific crossover.
The blend of different settings. Naruto's world has ninjas, chakra, and hidden villages. Z Nation has a post - apocalyptic, zombie - filled environment. When combined, it creates a whole new world full of possibilities. For instance, the idea of using ninjutsu to find a cure for the zombie virus or using zombie - like stealth techniques in the ninja world is really fascinating. The fanfic also allows for unique character development. Characters from both universes have to learn from each other and grow in unexpected ways. For example, the survivors in Z Nation learn about discipline and loyalty from the ninja characters, while the ninja characters learn about survival in a world without chakra from the Z Nation survivors.
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.
One idea could be a crossover where Naruto characters end up in the Z Nation world. For example, Naruto with his shadow clone jutsu could be really useful against the zombies. He could send out clones to distract the zombies while the group tries to find a safe place.
A big plot twist could be that one of the main Naruto characters gets bitten by a zombie but instead of turning into one, their chakra somehow mutates the virus and they become a super - powered anti - zombie being. This would completely change the dynamics of the story.
Well, one possible plot could be that Naruto and Goku somehow end up in each other's universes. Naruto could be intrigued by the concept of ki and try to learn it, while Goku might be interested in Naruto's ninja skills like shadow clones. They could team up to fight a common enemy, perhaps a new villain created by fusing some of the bad guys from both universes, like a combination of Orochimaru and Frieza.
Goku would likely win. Goku has the ability to reach extremely high power levels like Super Saiyan and beyond. His ki attacks are incredibly powerful and his speed is off the charts. Naruto is strong but his power is more limited compared to Goku's ever - increasing power scale in Dragon Ball Z.
One common theme is survival. Just like in Z Nation, the characters from Naruto also have to face new and extreme challenges, especially when the two worlds collide. Another theme is the adaptation of different power systems. The ninjutsu of Naruto in the context of Z Nation's setting.
In Naruto x Dragon Ball Z fanfiction, a really cool concept is the sharing of training methods. Naruto could learn about the gravity training that Goku does on Planet Namek. This would significantly boost his physical strength and speed. On the other hand, Goku might be interested in Naruto's chakra control training, which could potentially help him with his ki control in a different way. And when it comes to storylines, some fanfictions might involve the search for the Dragon Balls in the Naruto world, with Naruto and his friends joining Goku and his crew to find them, leading to all sorts of adventures and battles along the way.
