What are some interesting plot ideas for a 'breach of fate fanfic'?

Maybe a fanfic where Rex discovers a hidden talent of Breach that no one else knew about. For example, Breach is an amazing artist but has been hiding it. Rex encourages Breach to show it to the world, and through this process, their relationship blossoms. It could also involve some challenges from the other members who don't believe in Breach's new - found confidence.

A great plot for a Fate Tiamat fanfic could be a scenario where Tiamat tries to adapt to the modern world within the Fate universe. She has to deal with human culture, technology, and the other strange things she never encountered before. This could lead to some comical as well as deep and meaningful interactions with the other characters.

Well, you could focus on the concept of fate itself within the 'fate in time fanfic'. How about a story where the characters are aware of their fates but struggle against them? They could try to rewrite their destinies, which would lead to all sorts of interesting conflicts. Or perhaps a plot where fate is a sentient force that plays games with the characters, constantly changing the rules of time.

A good plot for a Brynhildr Fate fanfic could be a time - travel story. Brynhildr could be sent back in time to a crucial moment in her own history. She could then have the chance to change things that she regretted in her past. Or, you could write about Brynhildr falling in love with a character who is not from her original story. This would create a lot of interesting drama as she tries to balance her new feelings with her duties as a Servant. Also, a story where Brynhildr has to train a new and inexperienced Servant could be quite engaging.

One idea could be to explore an alternate timeline where the main characters make different choices at a crucial moment. For example, if a character who usually chooses to fight decides to negotiate instead, how would that change the course of the story? Another plot could involve a new character being introduced who has a special power that disrupts the existing power balance in the 'game of fate' world. This new character could either be a force for good or evil, depending on their motives.

One idea could be exploring Arjuna's relationship with other Servants in a modern-day setting. For example, how he adapts to living among them and dealing with modern technology.

One idea could be exploring how the different kingdoms deal with the aftermath of the breach. For example, Vale might focus on rebuilding its defenses and strengthening security. Another could be the character development of Team RWBY. Maybe Ruby becomes more determined to prevent future attacks and starts training even harder. Weiss could use her family's resources to help in the restoration efforts.

One idea could be that the Servants from Fate end up in the RWBY world and have to team up with the RWBY characters to fight a new common enemy. For example, a powerful Grimm that has some sort of magic ability similar to a Servant's Noble Phantasm. Another plot could involve the RWBY characters being summoned into the Fate universe and having to participate in the Holy Grail War, but with their own unique skills and abilities that disrupt the normal flow of the war. A third idea might be that a mysterious force starts fusing the two worlds together, and the characters from both have to figure out how to stop it while also dealing with the cultural and power differences between them.

One idea could be that Rex and Breach are forced to team up against a new, powerful EVO that threatens their mutual interests. Along the way, they start to understand each other's pasts and develop a grudging respect. For example, Rex could learn about Breach's difficult upbringing in the Nanite Collective and start to see her in a new light.

The protagonist is always a popular choice. You can develop their character further, explore their unspoken thoughts and feelings, and put them in new situations. For instance, in a 'breach of fate' fanfic, the main character might face a moral dilemma that wasn't in the original story.
