Maybe the main characters of both shows meet in a post - apocalyptic city. The more science - minded characters from 'Z Nation' try to study the walkers from 'The Walking Dead' to see if there are differences in the virus strains. This leads to a series of adventures as they protect each other from zombie attacks during the research.
Definitely Murphy from 'Z Nation' and Rick from 'The Walking Dead'. Murphy with his unique zombie - hybrid status and Rick as the natural leader. Their different leadership styles and views on survival would create a lot of interesting conflicts and cooperation moments.
First, choose the other universe you want to cross with. For example, if it's a superhero universe, think about how the powers would work in a zombie - infested world. Then, plan your characters' interactions. Will they be allies or enemies? Also, keep the tone of "The Walking Dead" - dark and gritty. Don't be afraid to make tough decisions for your characters.
A popular "Walking Dead" crossover fanfiction involves a crossover with "Game of Thrones". Imagine the politics and power struggles of "Game of Thrones" combined with the zombie apocalypse of "The Walking Dead". It's a wild ride as characters like Daryl Dixon and Jon Snow interact, with lots of unexpected plot twists.
A cool 'Walking Dead Crossover Fanfiction' idea is to cross it with 'The X - Files'. Mulder and Scully could be investigating the zombie outbreak. They might find out that it's not just a normal virus but some kind of government experiment gone wrong, which ties in with the conspiracy theories they usually deal with. And the characters from 'The Walking Dead' would be skeptical at first but then realize they need Mulder and Scully's help to figure out the real cause of the zombies.
One possible plot could be that Naruto and his friends somehow end up in the world of The Walking Dead. Naruto's ninja skills would be really useful in fighting off the zombies. He could use his shadow clone jutsu to create distractions while they look for supplies or a safe place. His friends like Sakura could use her medical skills to treat any survivors they come across. And Sasuke could use his sharingan to detect any hidden threats, either from the zombies or from other groups of survivors.
It could be really interesting. Picture Naruto and his ninja skills in the post - apocalyptic world of The Walking Dead. He might use his shadow clone jutsu to distract the walkers while finding a safe place for his group. His speed and agility from being a ninja would also give him an edge in combat against the undead.
Well, 'The Lone Survivor in Z Nation' is a popular one too. It tells the story of a single person who manages to outwit the zombies and other dangerous groups all by themselves. The way the author describes the survival tactics is really engaging.
If we consider a crossover with 'Star Trek', Captain Kirk would be a fascinating character to include. He's used to exploring new worlds and dealing with strange situations. In 'The Walking Dead' universe, he could use his leadership skills to organize the survivors. His optimistic and adventurous spirit might inspire the survivors to look for a better solution than just constantly running and hiding from the zombies.
