Another interesting plot could be a love story. Picture a character from RWBY falling in love with a character from Shuumatsu no Valkyrie. This would face many challenges, such as the differences in their worlds, cultures, and the fact that they are both often in the middle of dangerous situations. But their love could be a force that brings their two worlds closer together.
First, you need to understand the characters from both series well. Know their personalities, their backstories, and their goals. This will help you write them in a way that is true to their original selves. For example, Ruby from RWBY is very optimistic and determined, while Thor from Shuumatsu no Valkyrie is strong - willed and confident in his power.
It's about a battle royale - style setup where gods from different mythologies battle against humans. The Valkyries play a role in setting up these battles.
The Valkyries are likely to be the main characters. They are central to the concept as they are the ones doing the reading of the story.
Some of the main characters are the Valkyries, and of course, the human and god participants in the battles.
Well, one interesting plot point could be how the Valkyries' unique abilities are incorporated in the fanfiction while reading the story. Maybe they use their powers to influence the outcome of the events in the story they are reading.
One idea could be a crossover where Naruto characters are transported to the Valkyrie universe. They could team up with the Valkyries to fight a common enemy, like an ancient evil that threatens both worlds. Naruto's skills in ninjutsu would be a great addition to the Valkyries' combat capabilities.
One idea could be a story where Captain Marvel and Valkyrie team up to fight a new, powerful enemy that threatens the entire universe. They start off not getting along due to their different fighting styles and personalities, but as they face challenges together, they learn to respect and rely on each other.
One possible plot idea could be that they are in the middle of a battle, and in a moment of victory and adrenaline, they share a passionate kiss. It could be a turning point in their relationship, from comrades in arms to something more romantic.
A more complex plot could involve time - travel. Maybe an enemy from the past is brought to the present and is causing chaos. Peter and Valkyrie are brought together by Doctor Strange or some other powerful character to fix the timeline. They have to travel to different time periods, including Asgard in its prime and Peter's past in Queens. Along the way, they discover secrets about each other and the MCU universe as a whole.
Another plot could involve Nora somehow getting access to Naruto's chakra system. This could lead to her developing new powers similar to Naruto's. They might train together, with Nora teaching Naruto about the different Dust types in her world while Naruto shows her more advanced chakra control techniques. Their combined skills could then be used to face a powerful common enemy.
