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.
They could start as enemies. Kunzite is a powerful minion of the Dark Kingdom, and Sailor Venus is a Sailor Guardian. Their first encounter might be intense, full of magical attacks and defenses. But as the story progresses, they find out that there is a third, more powerful enemy emerging that threatens both their worlds. This forces them to work together, at least temporarily.
One possible story could be a meeting between Sailor Venus and Kunzite in an unexpected place. Maybe in a modern city setting where Sailor Venus is on a normal day out, and she stumbles upon Kunzite who is up to some mysterious business. Their encounter could lead to a battle at first, but then they realize they might have some common goals regarding protecting the world from a greater evil that neither of their sides were fully aware of.
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 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 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 interesting plot idea could be Serena and Darien getting lost in a magical realm together. They'd have to rely on each other's strengths, like Serena's optimism and Darien's calmness, to find their way back. Another could be a story where they swap powers for a day, leading to humorous and challenging situations as they adjust to the new abilities. And perhaps a plot where they go back in time to prevent an event that would have separated them in the future.
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.
