Perhaps in a fanfiction, Sailor Venus discovers a hidden side of Kunzite that is not as evil as she initially thought. This could lead to a series of events where she tries to convince the other Sailor Scouts that he might be redeemable. And then there could be a lot of internal conflict within the group as they debate this.
Maybe their powers can be combined when they perform a special ritual together. They have to stand in a certain formation, chant some ancient words, and then their powers start to interact. Sailor Venus' love - based powers could mix with Kunzite's more combat - oriented powers to form a power that has both offensive and defensive capabilities. This would be a very interesting way to show how two very different power sources can work together in fanfiction.
One interesting Naruto Sailor Venus fanfiction could be a crossover where Sailor Venus ends up in the Naruto world and has to learn ninja techniques. Maybe she uses her Sailor powers in unique ways to combat the villains in the Naruto universe.
One interesting plot idea could be a time - travel scenario where Sailor Moon goes back in time to prevent a major event that led to the rise of a powerful enemy. Another could be a crossover with another popular anime, like having Sailor Moon meet Naruto and they team up to fight a new threat.
One plot idea could be that Jadeite is actually a double agent and teams up with Sailor Mars to take down a common enemy. They start off as adversaries but as they work together, they begin to understand each other's motives.
One plot idea could be that Nephrite, instead of being an enemy, is reformed early on. He and Sailor Jupiter start to bond over their shared love for nature. They might work together to protect a park that is under threat from a new, unknown evil. This would be a fresh take on their relationship, showing how they could be allies.
One common theme is her identity. Since Sailor Venus has a bit of a mysterious past in the original series, many fanfictions explore more about who she really is. Another theme is friendship. How she interacts with the other Sailor Scouts and how their friendships are strengthened or tested.
One possible plot could be that Usagi is in a bit of trouble, like being chased by a youma. Sailor Venus, being the first to show up, saves her. Then, they start to wonder about each other's identities. Maybe Venus gives Usagi some clues about the Sailor Guardians without fully revealing herself. This could lead to Usagi being more curious and starting her own investigation.
Well, there's this fanfiction called 'Sailor Mars and Sailor Venus: A New Chapter'. It takes an interesting approach where they go on a journey to discover a new power source together. The author does a great job of building their relationship in a unique way. Also, 'The Red and the Gold' is a fanfic that focuses on their different personalities and how they complement each other in the fight against evil.
Well, in Sailor Moon dark fanfiction, a cool plot could be the Sailor Guardians facing an enemy that can manipulate their worst fears. This would make them question their own abilities and loyalties. Also, a story where the power source of the Sailor Guardians is somehow tainted, turning their powers dark and making them struggle to control it. Or perhaps a plot where a new dark Sailor Guardian emerges, with powers equal to or greater than Sailor Moon's, causing chaos in the magical world.
One idea could be that the characters from RWBY end up in the Sailor Moon universe and have to learn the ways of the Sailor Scouts. For example, Ruby could be intrigued by Sailor Moon's transformation and try to adapt her Crescent Rose to work in that magical world.
