For Wolfenstein crossover fanfiction, you could do a crossover with a cyberpunk world. Picture the Wolfenstein characters in a neon - lit cityscape filled with hackers, cyborgs, and mega - corporations. They could be fighting against a new form of Nazi regime that has integrated cybernetic enhancements. Also, a crossover with a space - opera setting could be cool. The Wolfenstein heroes traveling through space and battling Nazis on different planets.
One idea could be a crossover with a steampunk universe. The Wolfenstein characters could find themselves in a world full of gears, steam - powered machines, and zeppelins. Another could be a crossover with a post - apocalyptic setting, where they have to deal with new threats and challenges. Maybe also a crossover with a magical realm, and see how the high - tech weapons of Wolfenstein fare against magic spells.
In a Doom and Wolfenstein crossover fanfiction, it could be that there is a portal that opens between the two worlds. The demons start pouring into the Wolfenstein world, and BJ has to reach out to the Doom Slayer for help. The Doom Slayer brings his arsenal of powerful weapons, and together they train the resistance fighters in Wolfenstein to use these weapons. They also discover that some of the Nazi technology can be modified to be more effective against the demons, creating a unique blend of combat strategies from both universes.
You could also write a fanfiction that focuses on the relationship between different resistance groups in the Wolfenstein universe. Maybe there are tensions and power struggles among them, and exploring how they overcome or succumb to these issues can make for an engaging story.
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.
Well, in Wolfenstein RWBY fanfiction, a cool concept is the character crossovers. Imagine Ruby Rose from RWBY getting her hands on some of the advanced weaponry from Wolfenstein. It could lead to some really exciting action scenes. Also, the moral and ethical themes from both universes could be blended. The fight against oppression in Wolfenstein and the hunt for justice in RWBY could create complex storylines where characters have to make tough decisions.
A really cool idea for a RWBY and Wolfenstein fanfiction crossover would be to have the Dust from RWBY be a valuable resource that the Nazis in Wolfenstein are after. This would bring the two universes into conflict as the RWBY characters try to protect the Dust from falling into the wrong hands. Also, the different semblances of the RWBY characters could add a unique dynamic to the battles against the Nazi forces.
A significant theme is the combination of different aesthetics. The dark, gritty, and often steampunk - ish look of Wolfenstein combines with the more modern and diverse look of Worm. There can also be a theme of discovery, where characters discover new things about themselves or their powers when exposed to the other universe. This can lead to character growth and development as they face new challenges and opportunities outside of their original settings.
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.
One idea could be a crossover with a modern military setting. The Decepticons could be trying to steal advanced military technology. Another is a crossover with a post - apocalyptic world where they are competing with other factions for resources. A third could be a crossover with a magical realm, with the Decepticons trying to harness the magic for their own evil purposes.
One idea could be a crossover with Naruto. Kakuzu could be sent to the Naruto universe and form an unlikely alliance with a shinobi village to fight a common enemy, like the Akatsuki from his own world turned rogue in the new universe. This would create a lot of interesting character dynamics and battles.
Another option is a crossover with 'The Little Mermaid'. The characters from the descendants could meet Ariel and her friends underwater. Evie might be interested in the mermaid fashion and could design new outfits inspired by the underwater world.
