One interesting plotline could be a friendly sparring match that turns into a real test of skills and teamwork for both RWBY and JNPR. Maybe there are unexpected alliances formed during the fight.
Another plotline could involve a magical or technological mishap that swaps the abilities or personalities of the members of RWBY and JNPR. This would lead to a lot of chaos and confusion at first, but as they figure out how to deal with the situation, they also gain a deeper understanding of each other.
In some fanfictions, there might be a plot where a common enemy forces RWBY and JNPR to compete in a series of challenges in order to save their school or something they hold dear. This could lead to both teams learning from each other's strengths and weaknesses. For example, RWBY might learn more about strategic planning from JNPR, while JNPR could pick up some new combat techniques from RWBY.
One interesting RWBY JNPR fanfiction could be about the team's adventures outside of Beacon. For example, a story where they explore an ancient, forgotten part of Remnant filled with new Grimm and undiscovered relics. They might face challenges that test their teamwork and individual skills in ways not seen in the main series.
Another plotline might involve RWBY characters interacting with Earth's superheroes if they exist in the fanfiction. They could team up or have misunderstandings and battles.
Ruby from RWBY is often really popular. Her determination and unique weapon make her stand out. In the context of RWBY vs JNPR fanfiction, she can bring a lot of action and leadership to the story.
A plot could revolve around a new, powerful enemy that specifically targets Team JNPR. This enemy has studied their weaknesses and uses that knowledge to try and take them down one by one. The team then has to overcome their individual insecurities and grow stronger as a unit to defeat this foe. For example, Nora might have to face her fear of being alone, while Ren has to deal with his struggle to open up more emotionally.
One interesting RWBY and JNPR fanfiction could be 'Teamwork and Trust'. It focuses on how the two teams work together in a mission that wasn't shown in the original series. Another is 'New Beginnings for RWBY and JNPR' which explores what would happen if the characters had to start over in a different world. And 'JNPR's Support for RWBY' shows the great support JNPR gives to RWBY during a difficult time in Vale.
Romance is also a common theme. There could be stories about the relationships between members of JNPR and Rose. Maybe a love story between a character from JNPR and one from Team RWBY.
Well, they might have a whole range of reactions. Ruby could be really excited, seeing all the different takes on their adventures. Jaune might be a bit embarrassed if there are some fanfictions that focus on his more clumsy moments.

Maybe they'd even get some inspiration for their own real - life battles and challenges from the creative ideas in the fanfictions.
A great plotline might involve the deaged characters interacting with their younger selves' memories. Weiss could be haunted by her family's expectations in a new light, as if seeing them for the first time all over again. This could lead to her making different choices and growing in a whole new direction.
One possible plotline could be a character sacrificing their own powers to save their friends from a powerful enemy. For example, Ruby might give up her Silver - eyed Warrior abilities to stop Salem's latest scheme and protect her team.
Well, in some rwby mugetsu fanfiction, there might be a plotline where the characters have to adapt to a new world that combines the two settings.

This would lead to her character growth as she overcomes these challenges.
