One possible plotline is that Fem Naruto sees a future where her friends are in danger.

In this fanfiction, the Flood might return in a more evolved and dangerous form.

They might have to explore long - forgotten Forerunner technology or even make unthinkable sacrifices.
Well, one possible plotline could be the characters' future careers. For example, Rachel might be a huge Broadway star and the fanfiction could explore her struggles and triumphs on the big stage.

Or perhaps the New Directions group reunites for a special performance and they have to overcome old rivalries and new obstacles to make it a great show.
One possible plotline could be that the characters from Frozen enter a time - traveling adventure and witness different versions of their future.

And Kristoff might see his future with Anna and their family.
One possible plotline could be Naruto achieving a new level of power and using it to bring long - lasting peace to the ninja world. He might train a new generation of ninjas with his enhanced skills and wisdom.

Perhaps a plotline where the values that Mao Zedong represented, like equality and the fight for the common good, are transferred to the RWBY universe. The RWBY characters could be inspired to fight not just for themselves but for all the people in the kingdoms. They could start new initiatives like ensuring equal access to training for all those who want to be huntsmen or huntresses, similar to how Mao Zedong fought for the rights of the common people in China.
Maybe a plot where Glynda's telepathy is somehow affected by an outside force. This could lead to her losing control over it at times and causing chaos, and she has to find a way to regain control and fix the problems it causes.

One plotline could be that Penny is hacked by an enemy and turned into a brainwasher to manipulate her friends in RWBY. This would create a lot of internal conflict as the team tries to figure out what has happened to her.
Well, a possible plotline could start with Ruby being somehow infected or cursed to become a Grimm. She would then experience a whole new set of emotions and abilities. Maybe she starts to have visions or dreams related to the Grimm's origin or their purpose. As she tries to understand what has happened to her, she might be ostracized by some of her friends who are afraid of her new form. However, a few might believe in her and help her. She could then try to use her new Grimm - like abilities, such as enhanced strength or stealth, to fight against a greater evil that is threatening both the Grimm and the people of Remnant. Along the way, she could learn more about the true nature of the Grimm and find a way to either reverse her condition or fully embrace it in a way that benefits everyone.
