The plot could involve a portal opening between the RWBY universe and the Fallout universe. The RWBY team has to find a way to close it while also dealing with the various threats in the Fallout world. They might team up with some of the more friendly factions in Fallout, like the Brotherhood of Steel. Ruby would be intrigued by the advanced, albeit often malfunctioning, technology in the Fallout world and try to learn from it to enhance her own weapon.
One possible plot could be that the RWBY characters find themselves in the Fallout wasteland. Ruby could use her scythe skills to fight off the mutated creatures in the wasteland. Weiss might struggle with the harsh and dirty environment compared to her usual posh settings but use her glyphs in unique ways against raiders. Blake could use her stealth to navigate dangerous areas, and Yang's strength would be useful in hand - to - hand combat with the tough Fallout foes.
In a RWBY Fallout crossover fanfiction plot, the world of RWBY is hit by a strange radiation - like event similar to the nuclear apocalypse in Fallout. The characters start to develop new abilities and face new challenges. For example, Weiss may find that her ice powers are affected by the radiation, becoming more powerful but also harder to control. They then have to explore this new world, filled with both remnants of their old world and new Fallout - style threats.
A plot could involve a group of vault - dwellers from the Fallout world accidentally stumbling into Zootopia. The animals in Zootopia are initially suspicious and scared of these strange new creatures. However, they soon realize that they need to work together. The vault - dwellers bring with them advanced technology that could help Zootopia deal with some of its own problems, like energy shortages. In return, the animals in Zootopia offer their unique skills, such as the speed of the cheetahs for scouting or the strength of the rhinos for defense.
Well, it could be about the RWBY characters finding themselves in the Doom universe. Maybe Ruby and her team are trying to fight off the demons in Doom while also using their own unique abilities. They might team up with the Doom Slayer at some point to take on a big, bad enemy that threatens both universes.
One idea could be that the RWBY characters find themselves in the Fallout wasteland. Ruby could use her Crescent Rose to fend off mutants. Weiss might struggle with the harsh and dirty environment compared to her usual clean Atlesian surroundings. Blake could use her stealth skills to navigate dangerous areas, and Yang's strength would be useful in combat against raiders. They could be on a quest to find a way back to their own world while also trying to make the wasteland a better place.
One idea could be that the characters from RWBY end up in the Fallout wasteland. Ruby could use her scythe skills to fight off raiders and mutants. Weiss might use her glyphs to protect the group from radiation in certain areas. Another idea is that the Dust from RWBY could be a valuable resource in the Fallout world, leading to various power struggles.
RWBY's reactions could vary greatly. Yang would probably be excited about the action - packed parts of the fanfiction. She loves a good fight, and Fallout often has intense combat scenes. Ruby would be drawn to the unique characters, especially those with special powers or abilities. Weiss might be more interested in the social hierarchies and how they function in the Fallout world. And Blake could be thinking about how the stories in the fanfiction could be used to teach lessons about coexistence and conflict resolution in her own world.
One possible plot could be that Doflamingo somehow ends up in the RWBY world. He might initially try to take over, using his strings to manipulate the Grimm. But the RWBY team discovers his true nature and battles him. Ruby could use her speed to avoid his string attacks while Weiss uses her glyphs to counter his powers.
Another plot could be that an evil force in the RWBY universe discovers the existence of the Omnitrix from another dimension. They manage to create a device to pull Ben and the Omnitrix into their world. Ben has to adapt quickly to this new world while Team RWBY, who are initially suspicious of him, realizes that he could be an ally against this new threat. They join forces, with Ben using his alien forms in creative ways to combat the Grimm and the evil force's minions.
A possible plot is that the RWBY characters end up in New York. Ruby, with her speed and scythe skills, is initially mistaken for a threat by Spiderman. But when they realize they are both on the side of good, they join forces. Weiss could use her glyphs in new and creative ways in the urban environment, Blake's stealth and acrobatic skills could be put to great use, and Yang's strength would be a valuable asset. Together they take on a criminal organization that has somehow gotten hold of some Dust and is using it for evil purposes.
One possible plot could be that Spider - Man gets transported to the RWBY universe. He might initially be confused by the Grimm and the Huntsmen and Huntresses. Maybe he teams up with Team RWBY to fight a new type of threat that combines the technology - based villains from his world and the Grimm from RWBY. For example, a villain could be using some sort of Dust - powered tech to create super - Grimm. Spider - Man's agility and web - slinging abilities would be a great addition to the RWBY team's combat styles.
Well, it could be about Red Hood getting transported to the RWBY world. He might team up with Ruby and the gang against some common enemy like Salem. His combat skills and no - nonsense attitude would be a great addition to the RWBY team.
