Well, Dean Winchester would probably be a bit of a loose cannon in the Walking Dead world at first. He's used to dealing with monsters that are a bit more intelligent than the walkers. But his survival instincts would kick in quickly. Sam would be more methodical, trying to analyze the situation. And if they showed up, they might be seen as a threat by Rick's group initially. However, once they prove they can help, they could start sharing their knowledge. For example, Sam could teach some of the survivors about how to create protective sigils against any potential supernatural threats that might be related to the walkers.
The characters from Supernatural would bring their unique skills. Dean, for instance, is an excellent marksman and fighter. He could easily adapt to using guns against the walkers. Sam, with his knowledge of the occult, might be able to figure out if there's a deeper, supernatural reason for the zombie outbreak. Castiel, the angel, could use his powers to heal the injured in Rick's group or even fly over areas to scout for threats. They would add a new dimension to the fight for survival in The Walking Dead world.
If Castiel were to be in this crossover, he would be very confused by the walkers at first. He's used to dealing with demons and angels, not undead creatures. But he would quickly adapt and use his angelic powers to protect the group. Rick from The Walking Dead would see Castiel as a valuable asset but also be a bit wary of his otherworldly nature. They would have to learn to trust each other as they both have the goal of protecting the survivors and finding a way to end the chaos in their respective worlds.
Well, first of all, they would be horrified by the sheer number of undead. But then, they would start using their unique abilities. Neville could use his skills in Herbology to find plants that might be useful in repelling walkers or curing diseases. Luna Lovegood might have some interesting insights into the walkers' existence, seeing them as some sort of magical - like creatures. The wizards would also have to learn how to be more stealthy, as magic can attract unwanted attention. They might start wearing the clothes of the survivors to blend in better and not stand out as targets for the walkers.
In this crossover, Naruto's Rasengan could be a powerful weapon against the zombies. He could spin through a group of zombies, taking them out in one go. Hinata's Byakugan could be useful for surveillance, being able to see in all directions and detect any approaching zombies long before they get close. Shikamaru, with his high intelligence, could come up with strategic plans to navigate through the zombie - infested high school, using the abilities of both the Naruto and Highschool of the Dead characters effectively.
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.
One great plot idea could be that the Winchesters from Supernatural find themselves in the world of The Walking Dead. They could use their hunting skills to fight off the walkers in a unique way. Maybe they think the walkers are some kind of supernatural creation at first and try to find a way to cure them like they do with monsters in their own world.
You can start by looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms have a vast collection of fan - created stories, and you can simply search for 'Walking Dead Supernatural crossover' in their search bars.
The Chosen Undead from Dark Souls could be seen as a mutant in the Marvel Universe with their ability to keep coming back to life. They might be shunned at first like many mutants are, but then prove their worth when facing threats. Their combat skills with swords and shields would be a unique addition to the fight scenes in the Marvel Universe. For example, they could fight alongside Wolverine, and their different fighting styles would create an interesting contrast.
In this kind of crossover, Gaara could be a fascinating character to focus on. His ability to control sand could be used in really creative ways against the zombies, like creating barriers or using sand - based attacks. From 'The Walking Dead', Michonne would be great. Her katana - wielding skills are similar to the ninja sword skills in the Naruto world, and she could learn some new moves from the ninjas. Also, Naruto's teacher Jiraiya. His knowledge of various jutsus and his overall wisdom could be key in coming up with strategies to deal with both the zombies and any new threats that come from the crossover of the two worlds.
Dean Winchester would likely be charmed by Lorelai Gilmore's sass and sense of humor. He might also be a bit protective of her, given his nature. Sam would probably have in - depth conversations with Rory about books and knowledge. Rory, in turn, would be fascinated by Sam's experiences with the supernatural. And Luke would probably be a bit suspicious of the Winchesters at first, thinking they're up to no good in his town.
Fairy Tail characters can use their unique abilities. For instance, Erza could use her different armors to fight the zombies. Her requip magic would allow her to quickly change her equipment depending on the situation, whether it's a long - range battle against a large group of walkers or a close - combat situation.
