What are some interesting plot ideas for an RWBY Summer Brother fanfic?

A great plot idea for a RWBY Summer writing fanfic is to explore Summer's relationship with a mysterious character. Maybe there was someone she met during a summer festival who had a connection to an ancient power. As she gets closer to this person, she discovers that there are dark forces at play trying to use this power for evil. Or you could write about Summer's attempt to break a summer - long curse that has been plaguing a small village.

A great plot could be centered around the Summer Maiden's relationships. For example, she might have a forbidden love with a character from the other side, like a member of Salem's faction. This would create a lot of internal conflict as she has to balance her feelings with her duty as a Maiden. Or perhaps she has a deep friendship with a character who is in danger, and she has to use her powers to save them from a great threat.

One idea could be a story where Pyrrha and Summer are brought back to life in an alternate reality. They then have to team up to face a new, powerful threat that is endangering their world. Another plot could involve a pre - RWBY story where Pyrrha and Summer meet during a training mission and learn from each other's skills.

Perhaps Si is transported back in time to when Summer was alive. Si then has the chance to interact with Summer directly. They could become friends and go on adventures together. Along the way, Si could learn valuable lessons from Summer and also change some small events that have a big impact on the future of the RWBY world.

One idea could be a choice where the characters have to decide whether to ally with a mysterious new group in Vale. This new group seems to have some unique powers and resources, but their motives are unclear. It could lead to different story arcs depending on the choice made.

One idea could be a character getting a tattoo that has a hidden power. For example, a RWBY character might get a tattoo that glows when danger is near, like a warning sign. Another plot idea could be a story centered around a tattoo artist in the RWBY universe who creates unique tattoos for the Huntsmen and Huntresses, and each tattoo gives them a special ability or connection to the Dust energy. Maybe a tattoo that allows a character to communicate with Grimm in a strange way, adding an interesting twist to the story.

One idea could be a story where the characters from RWBY have to face a new, extremely powerful Grimm that has unique abilities. This Grimm could be immune to certain types of Dust, forcing the team to come up with creative combat strategies. Another plot could involve a tournament within the RWBY battlefield, where different teams compete not just for victory, but also for a rare and powerful relic. This would add an element of competition and strategy among the characters.

Perhaps Sasuke is mistaken for an enemy at first. His strange powers and appearance raise suspicion. But as the story progresses, it's discovered that he has knowledge of a greater threat that is coming to the RWBY world, something that might be related to his own past experiences. So he teams up with the RWBY characters to prepare for this threat.

One idea could be the RWBY characters teaming up with the Payday gang to steal some valuable Dust from a powerful and corrupt company. They'd have to use their unique skills, like Ruby's speed and Crescent Rose, combined with the Payday crew's heist expertise.

One idea could be the young RWBY characters having a mini adventure in the woods near their homes. They might discover a strange creature and try to befriend it. Another could be them having a pretend battle tournament in their backyard, with each using their unique abilities in a more innocent and unrefined way.
