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.
Another interesting plot could involve Nephrite losing his memory and Sailor Jupiter finding him. She initially doesn't trust him but as she tries to figure out what happened to him, she starts to see a different side of him. They could develop a tentative friendship that might turn into something more as he regains his memories and chooses to side with the Sailor Scouts.
A more complex plot could be set in an alternate universe where Sailor Jupiter and Nephrite are from different factions that are at war. However, they meet in secret and discover that their respective sides have been manipulated by a greater evil. They then have to decide whether to expose the truth and risk everything, including their new - found relationship.
Well, in the original, Nephrite was an enemy. But in fanfiction, their relationship could start with Nephrite being curious about Sailor Jupiter's strength. He might approach her not as an enemy but as an observer, and this could lead to conversations that gradually make them friends. For example, he could see her fighting and be impressed, then start to ask her about her powers.
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.
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.
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 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.
An interesting plot could be that Goku and Sailor Moon meet during a multiverse tournament where representatives from different anime universes are competing. They initially don't get along because of their different fighting styles and beliefs, but as the tournament progresses, they realize they can learn from each other. Together, they face off against a cheating opponent who is using unfair tactics to win. Through their combined efforts, they not only defeat the opponent but also learn to respect each other's worlds and ways of fighting.
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.
In Sailor Moon fanfiction, a kiss between Jupiter and Mercury could be a really interesting concept. It might happen in a situation where they are sharing a deep emotional moment. For example, perhaps they have just overcome a great enemy together and in the heat of the victory, their feelings for each other surface and lead to a kiss. This could also be part of a more complex relationship development within the Sailor Moon universe, where their friendship takes a new turn.
One interesting plot idea could be that Natsu, being a powerful fire mage, somehow gets transported to the Sailor Moon universe. He could team up with Sailor Mars, since they both have an affinity with fire. They might face a new enemy that is immune to normal attacks but is vulnerable to the combination of Natsu's dragon - slaying magic and Sailor Mars' spiritual powers.
