Well, it could be about a group of survivors from Z Nation somehow finding their way into the world of The Walking Dead. Maybe they bring with them some of their unique ways of dealing with zombies, like the Murphy cure concept, and it causes chaos or new hope in the Walking Dead universe.
One possible plot could be that the survivors from both Z Nation and The Walking Dead meet by chance. They initially have some conflicts due to their different survival methods. For example, the group from Z Nation might be more open to using extreme measures against zombies, while the group from The Walking Dead has a more moral - centered approach. But as they face a huge horde of zombies together, they are forced to cooperate. They learn from each other's strengths and finally manage to defeat the horde and start to consider building a new community together.
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 has his unique zombie - human hybrid status which gives him some extraordinary abilities. Rick, on the other hand, is a natural leader. Putting them together would create a lot of interesting dynamics. They might clash because of their different leadership styles, but also might find common ground in their goal to protect their people.
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.
I think Murphy from Z Nation and Rick from The Walking Dead would be really interesting. Murphy has his whole zombie - like but still somewhat human situation going on, and Rick is a natural leader. Rick would be both intrigued and probably a bit wary of Murphy. Their interactions could be full of tension as Rick tries to figure out if Murphy can be trusted and if his 'condition' could be useful in some way against the walkers.
In a crossover fanfic, the angels and demons from Supernatural could be involved in The Walking Dead universe. For example, an angel might be sent to Earth to stop the spread of the undead, believing it's part of a grand plan to save humanity. Meanwhile, the demons could be taking advantage of the chaos, making deals with desperate survivors. The Winchester brothers would have to navigate this new dynamic while also dealing with the walkers.
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".
