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.
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 story could be a crossover where Goku and Sailor Moon team up to fight a common powerful enemy from both their universes. Maybe an evil force that combines the dark magic from Sailor Moon's world and the powerful villains from Dragon Ball.
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.
One idea could be a story where a new Sailor Guardian emerges from a different dimension and has a unique power that can either help or hinder the fight against the Black Moon Clan. For example, she might be able to manipulate time in a different way than Sailor Pluto. Another plot could involve a member of the Black Moon Clan who has a change of heart and decides to secretly assist the Sailor Guardians. This would create a lot of internal conflict within the clan.
Well, a cool plot might be that the Dragon Balls are stolen by an evil force from the Sailor Moon universe. So, the Z Fighters have to travel to that universe to retrieve them. Along the way, they meet the Sailor Scouts and realize they need to work together. The Sailor Scouts could also learn about the power of the Dragon Balls and how they can be used for good. They might even help the Z Fighters in their search by using their unique powers to track down the stolen balls.
One idea could be that Prince Diamond has a change of heart after getting to know Sailor Moon better. Instead of being an antagonist, he becomes an ally and helps her fight a new, greater evil. For example, a powerful dark force from another dimension emerges and they have to combine their powers to defeat it.
Well, perhaps Naruto has a special power that is needed to save both his world and the Sailor Moon world. As a result, the female characters from both Naruto and Sailor Moon start to develop feelings for him. For example, Sailor Moon might be drawn to his never - give - up attitude, while Sakura from Naruto could see a new side of him in this strange new setting.
Maybe there could be a dark force that is threatening both the Inuyasha world and the Sailor Moon world. So, Sailor Moon and her Sailor Guardians team up with Inuyasha, Kagome, and the others. They could combine their powers in unique ways. For example, Sailor Moon's healing powers could be used on Inuyasha when he gets seriously injured in a fight against the common enemy, and Inuyasha's strength could be used to protect the Sailor Guardians from some of the more physical threats in his world.
One plot idea could be that Zim discovers the power of the Sailor Scouts and tries to use it for his own evil plans. Maybe he thinks he can use their magic to finally take over Earth in a more powerful way.
