Hermione would probably be very interested in studying the situation in The Walking Dead world. She might try to find a scientific or magical explanation for the zombies. The survivors from The Walking Dead, like Rick, would be initially skeptical of the magic but would soon see its value. The Mashone could act as mediators, helping both sides understand each other. For instance, they could explain the ways of the Potter world to the survivors and vice versa.
In a fanfiction, Harry Potter himself could use his skills in Defense Against the Dark Arts to fight the zombies. He would be amazed at the survival skills of the characters from The Walking Dead. Daryl, for example, could teach Harry some of his hunting and tracking skills. The Mashone could bring in their own cultural elements. Maybe they have a special way of communicating that helps in coordinating between the two groups. They could also have unique magical abilities that are different from what's seen in the Potter world and use them to everyone's advantage.
If we think about Snape, he would be a complex character in this crossover. He might initially think the survivors of The Walking Dead are unworthy of his help. But as he sees their determination, he could change his mind. The characters from The Walking Dead would be in awe of the magic potions and spells. The Mashone could be a group that has a deep understanding of both magic and survival. They could help the Potter characters understand the harsh reality of the zombie - infested world and also help the Walking Dead characters appreciate the power of magic.
