What are some interesting plot ideas for Red vs Blue and Overwatch crossover fanfiction?

Maybe the Caboose could cross over into a world where the rules of combat are completely different. His Red vs Blue training would be put to the test, and he'd have to adapt quickly. For example, instead of using guns, they use magic or some other form of power. The Caboose might initially be confused but then find his own way to contribute.

One idea could be that the Reds and Blues get transported to the RWBY world and have to learn how to use Dust to fight. They could team up with Team RWBY and face off against a new enemy that is a threat to both their universes. Maybe they introduce their unique sense of humor and combat styles to the RWBY characters.

Maybe a story where the Reds and Blues are transported to the RWBY world. They have to learn about Grimm and Huntsmen while trying to find a way back home. Along the way, they could team up with RWBY characters like Yang, who could teach them some hand - to - hand combat skills, which are different from their usual long - range tactics.

One plot idea could be the characters from Red vs Blue and RWBY teaming up to fight a common enemy. For example, a powerful Grimm that has somehow entered the Red vs Blue universe. Another could be the Reds and Blues getting involved in the Beacon Academy's classes and causing chaos with their unique combat styles. Maybe they could introduce their own brand of humor to the more serious RWBY world.

One idea could be to bring in characters from another similar sci - fi universe. For example, imagine if a character from the Halo series (since Red vs Blue has Halo - like elements) enters the Red vs Blue world. It could create a whole new dynamic with the existing characters. Maybe they have different combat styles or goals that would clash or align with the Reds and Blues.

One idea could be the teams from Red vs Blue and RWBY getting mixed up in a shared mission. Maybe the Reds and Blues end up in Remnant and have to learn how to use Dust and fight Grimm while the RWBY teams have to deal with the Reds and Blues' unique military tactics. Another plot could involve a villain that is causing chaos in both universes and the combined forces have to stop it.

Mercy and Doc would also be a great pairing. They are both medical personnel in their respective universes. They could exchange medical knowledge, with Mercy teaching Doc about some of the more advanced medical technology in the Overwatch universe, and Doc showing Mercy some of his improvised medical techniques that he's developed in the Red vs Blue world.

One possible interesting plot could be a battle tournament. Red - team Naruto characters and Blue - team characters from other ninja clans or villages. They compete in various challenges that test not only their combat skills but also their strategic thinking. The Red team might have Naruto's determination and unique jutsu like Rasengan, while the Blue team could have some rare and powerful kekkei genkai from other regions. This would create intense battles and unexpected alliances as the story progresses.

One idea could be exploring how Tucker's pregnancy affects his relationships within the Red vs Blue team. For example, how his friends support him or struggle to adapt to the situation. Another could be the challenges he faces during the pregnancy, like dealing with the physical and emotional changes while still being in a combat - oriented environment.

One idea could be a team - up between Ruby from RWBY and the Red team from Red vs Blue. They could face a common enemy that requires both their unique skills. For example, a new type of Grimm that has advanced technology, and the Reds' combat knowledge combined with Ruby's speed and scythe - wielding abilities would be needed to defeat it.
