What are some interesting ideas for an Overwatch RWBY crossover fanfic?

One interesting idea could be an Overwatch crossover with the world of Harry Potter. For example, Tracer could be a student at Hogwarts, using her time - traveling abilities in magical ways within the school. Another idea is a crossover with the Star Wars universe. Maybe Reinhardt as a Jedi, with his rocket hammer being a unique lightsaber - like weapon. And a crossover with the Lord of the Rings, where Orisa could be a guardian of a certain part of Middle - earth, protecting it from the forces of evil with her shield and gun.

One idea could be the Overwatch heroes being transported to the RWBY world. They could team up with Team RWBY to fight a new common enemy, like a powerful Grimm that is immune to normal attacks but vulnerable to Overwatch tech. Another plot could involve a character exchange, where a RWBY character like Ruby goes to the Overwatch world and learns about their technology and fighting styles, and then brings back new knowledge to her own world.

Another interesting concept could be a character swap. Imagine Tracer from Overwatch in the Halo universe, using her time - jumping abilities in the middle of a large - scale Halo battle. Or a Spartan in the Overwatch world, trying to adapt to the more urban and team - based combat scenarios there.

One idea could be that the RWBY characters are transported into the Overwatch universe and have to team up with the Overwatch heroes to fight a new common enemy, like a powerful omnic - Grimm hybrid. Another could be a friendly competition between the two groups in a series of combat trials to see who is more skilled.

One idea could be an Overwatch crossover with the Star Wars universe. Imagine Tracer using her time - traveling abilities in the middle of a lightsaber duel. Another could be a crossover with the Harry Potter world, like Pharah flying on her rocket launcher over Hogwarts. And a crossover with the Marvel universe, where Reinhardt teams up with Thor to fight some powerful villains.

A great idea for an RVB RWBY crossover fanfic could be a tournament - style story. Characters from both universes are forced to participate in a huge tournament. This would allow for a lot of different match - ups between the characters. The Reds and Blues' comical and sometimes unorthodox fighting styles would contrast with the more refined and trained fighting styles of RWBY characters. It could also lead to some interesting friendships or rivalries forming during the tournament.

One idea could be to have the Spartans from Halo end up in the RWBY universe. They could team up with the RWBY characters to fight against a common enemy like the Grimm. Maybe the Spartans' advanced technology would be a big advantage in battles.

Maybe the RWBY characters are on a quest in Skyrim to find a way back home. Along the way, they meet various characters like the Dark Brotherhood or the Thieves Guild. Ruby might befriend a young Nord who is also an aspiring warrior and learn some of the local combat techniques. Weiss could use her knowledge of Atlesian technology to improve some of the weaponry in Skyrim. Blake could uncover some secrets about the Daedric Princes that are related to the Grimm in some way, and Yang could participate in the Skyrim's famous brawls and earn a reputation as a fierce fighter.

A possible idea for a MHA RWBY crossover fanfic is to explore the idea of semblance and Quirk evolution. The characters from both shows could train together and discover new ways to enhance their abilities. For instance, Izuku Midoriya could learn from Ruby about using her Crescent Rose in combat and in turn, show her how to better control her power flow. The cultural differences between the two worlds could also add depth to the story, like how the heroes in MHA are more publicly recognized compared to RWBY, and how the characters react to this disparity.

One idea could be that Godzilla arrives in the RWBY world due to a strange dimensional rift. The Huntsmen and Huntresses initially see it as a huge threat and try to fight it. But then they discover that Godzilla is actually there to fight a common enemy, like a new type of Grimm that is immune to normal attacks but vulnerable to Godzilla's atomic breath.
