Well, a major theme is the power of the Necronomicon. It's always a key element in the fan fictions, whether it's about someone trying to get it, or Ash using it to fight the demons. Another common theme is the legacy of the evil. How the past actions and mistakes keep coming back to haunt Ash and the world. And of course, the theme of heroism. Ash is seen as a reluctant hero in a lot of fan fictions, but he always steps up to the plate when it matters.
Alternate universes are also quite popular. This could involve Ash in a completely different setting, like a modern - day city that has been overrun by evil but with a different set of rules or circumstances. It allows writers to be really creative and put their own spin on the Ash vs Evil Dead concept.
One potential father figure for Ash in fanfiction could be Professor Oak. He has been like a mentor and a guiding figure in Ash's life. He has given Ash his first Pokémon and has always been there to offer advice, which could easily be developed into a father - like relationship in fanfiction.
Another interesting concept for an Ash vs Evil Dead crossover fanfiction is to introduce a new villain that is a combination of different evil forces from both the movies and the show. This super - villain could be immune to some of Ash's usual tactics, forcing him to team up with unlikely allies. The fanfiction could explore how they figure out the villain's weaknesses and ultimately defeat it. It could also include some comical moments, like Ash's one - liners in the face of danger.
Fanfiction.net could also be a place to look. There are many different categories and tags related to Ash vs Evil Dead that you can browse through. However, the quality can vary, so you might need to sift through a bit to find the really good ones. Some users also leave reviews which can help you decide if a particular piece is worth reading.
Well, 'Ash vs Evil Dead: The Next Generation' is a cool fan fic. It imagines a future where Ash has trained a new group of demon hunters. It has some really interesting takes on how the Evil Dead world could evolve. Also, there's 'Ash in the Underworld' that takes Ash on a journey to the very place where the demons come from, full of dark and spooky scenarios.
Another theme is redemption. If the father figure has made mistakes in the past, like Giovanni perhaps, the fanfiction might focus on his journey to make up for those mistakes and be a proper father to Ash. This could involve him changing his ways and helping Ash in his Pokémon journey instead of causing trouble.
Gary could be the main antagonist. He has always been Ash's rival and seeing Ash turn evil, he might feel responsible to stop him. Gary could gather his own team of powerful Pokémon and use his wits to oppose Ash at every turn.
Making your Ash vs Evil Dead crossover fanfiction stand out can be achieved by incorporating elements from other horror or action franchises in a clever way. For example, you could borrow some concepts from 'Resident Evil' like a virus - like spread of the Deadite infection. Or perhaps introduce a character from another horror movie as a guest star in your story. This will give your fanfiction a fresh and unexpected feel, attracting more readers.
