Some great ideas for the witcher crossover fanfiction include a crossover with the Conan the Barbarian world. Geralt would fit right in with all the sword - fighting and monster - slaying. A crossover with the Legend of Zelda could also be fun. Geralt could explore the magical lands of Hyrule and encounter Link. Additionally, a crossover with the Berserk universe would be intense, with Geralt facing the demons and horrors that exist in that world.
One idea could be a crossover with the Lord of the Rings. Geralt could find himself in Middle - earth, facing off against orcs and perhaps teaming up with Aragorn. Another is a crossover with Harry Potter. Maybe Geralt is called to Hogwarts to deal with a magical beast that the wizards can't handle. A third idea is a crossover with Game of Thrones, where Geralt has to navigate the complex politics and battles of Westeros.
Maybe a Witcher potion - making concept could be introduced to the Hogwarts potions class. For example, a character from Harry Potter, like Hermione, could be intrigued by the complex and powerful Witcher potions. She might try to study them and combine them with her own magical knowledge. This could lead to new discoveries in both magical systems.
Well, a cool plot for a Witcher RWBY crossover fanfiction might involve the Witcher's magic and potions being introduced to the RWBY universe. For example, a potion that gives the RWBY characters temporary enhanced senses like a Witcher. Or perhaps a situation where a powerful Witcher villain comes to the RWBY world and the teams have to combine their skills to defeat him. The different fighting styles of the Witcher and RWBY characters would make for some really exciting battle scenes.
One idea could be that Geralt gets transported to the wizarding world. He could be mistaken for a very strange kind of wizard at Hogwarts. Maybe he's enlisted to help fight some dark magic that the regular wizards can't handle because of his unique skills in dealing with monsters. Another plot could involve Harry Potter being sent to the Witcher's world. He'd have to learn how to use a sword and deal with the more brutal and less rule - bound magic there. And a third idea is that a powerful dark force is threatening both worlds, so the Witchers and the wizards from Harry Potter's world have to team up. The Witchers could teach the wizards about physical combat and the wizards could share their more sophisticated spells with the Witchers.
One idea could be a werewolf OC who is trying to find a cure for his lycanthropy. He could team up with Geralt, believing that the witcher's knowledge of monsters might help. Another could be a female werewolf OC who is a protector of a small village, but is feared by the villagers. She has to balance her dual nature and prove her worth to the people.
One idea could be that Naruto, through some magical portal, ends up in the Witcher world. The Witcher characters are intrigued by his unique abilities like shadow clones. In the harem aspect, some female Witchers and sorceresses start to develop feelings for Naruto as he helps them fight against new, powerful monsters that are threatening their land.
One possible plot could be that Naruto, while on a mission in a strange new land, stumbles upon a portal that transports him to the Witcher's world. There, he meets Geralt and they initially have a misunderstanding due to their different cultures. But as they face a common enemy, like a powerful dark magic - using creature that is terrorizing the local villages. Naruto's unique jutsu abilities combined with Geralt's monster - hunting skills make for an exciting battle. They learn from each other's fighting styles and Naruto also gets to experience a different form of magic in the Witcher world.
One possible plot could be that Naruto, while on a strange mission, gets transported to the Witcher's world. He teams up with Geralt to hunt a powerful demon that has the ability to control minds. Naruto's unique ninja skills, like his shadow clones, would be very useful in distracting the demon while Geralt figures out its weakness.
One interesting idea could be a crossover with "Moana". Elsa's ice powers and Moana's connection to the ocean could create a really cool dynamic. Maybe Elsa accidentally freezes part of Moana's ocean and they have to work together to fix it. Another could be with "Tangled". Rapunzel's long hair and her adventurous spirit combined with Elsa and Anna's journey in Frozen 2 would be exciting. Rapunzel could use her hair to help them climb mountains or cross chasms. A third idea is a crossover with "Beauty and the Beast". Belle's love for books and knowledge could help Elsa understand more about her powers and the history of magic in the Frozen world.
Another plot might involve Yennefer and Geralt having to deal with a magical curse that affects their relationship in unexpected ways. For example, they might switch bodies and have to understand each other's struggles better. In the world of Witcher fan fiction, the possibilities are really endless. Writers can take the existing lore and twist it to create engaging stories.
A Rambo crossover fanfiction could involve him crossing over into the Star Wars universe. Rambo's guerilla warfare tactics could be interesting in a galaxy far, far away. Maybe he helps the Rebel Alliance in a ground - based battle against the Empire. Or a crossover with the Predator series. Rambo would be a worthy opponent for the Predator, and the fight between them in the jungle could be epic. Also, a Rambo and John Wick crossover would be intense, two highly skilled fighters on the same side or perhaps initially at odds.
