One way to combine them could be through a crossover universe. Imagine Sailor Moon's magical world colliding with Gotham City. Sailor Moon could bring her powers of love and justice to help Batman clean up the streets. Maybe the Sailor Scouts and Batman's allies could team up to fight a common enemy that threatens both their worlds, like an alien force that is drawn to Gotham's chaos and the magical energy of the Sailor Scouts.
They could be combined in a time - travel scenario. Batman somehow gets transported to the Sailor Moon universe. He would have to adapt to the new rules of magic and the more idealistic view of justice there. He could use his detective skills to help the Sailor Scouts solve a mystery that has stumped them, while they in turn teach him about the power of friendship and the importance of believing in the impossible.
Sailor Moon would probably be really curious about Batman. She'd be constantly asking him questions about his gadgets and his mission. Batman, being the brooding type, might be a bit annoyed at first but would soon realize her good heart. He'd start to respect her powers and they'd form an unlikely alliance.
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.
Well, in such a fanfiction, the art styles could be blended in an interesting way. The Sailor Scouts could have a new look inspired by Batman's aesthetic, like darker colored fuku with bat - like symbols. And Batman could get a touch of Sailor Moon's magic, perhaps his utility belt having some magical items. The story could explore how two very different universes collide, and how the characters grow from the experience.
One interesting crossover could be a story where Sailor Moon's magic and Batman's detective skills combine to solve a super - villain mystery that spans both their universes. For example, they might team up to stop a new villain who has the ability to manipulate time, a power that is of great interest in Sailor Moon's world and a threat to Batman's Gotham.
Some characters might laugh. If the fanfiction has humorous elements, like a comical take on their battles or relationships, they would find it entertaining. For instance, if there's a fanfiction where the Sailor Scouts accidentally swap powers and get into all sorts of wacky situations, the characters themselves might chuckle at the absurdity.
A really interesting plot twist could be that the villains from both universes are actually being controlled by a single, greater evil. For example, Queen Beryl and the Joker are being manipulated by an interdimensional being. This would force Sailor Moon and Batman to put aside their differences in fighting styles and beliefs to take on this new threat.
First, decide on the main plot. Will it be a crossover adventure where the characters meet? Or perhaps a story where the two worlds merge? Then, create unique characters or combine existing ones in new ways. For example, a trainer who has Sailor Scout powers.
Another fanfic concept is that there's a threat in Gotham that has a connection to the Moon Kingdom's past. Sailor Moon travels to Gotham to investigate. There, she meets Batman, who is initially skeptical of her magical powers. But as they start to work together, they realize that their skills are complementary. For example, Sailor Moon's ability to heal could be useful for Batman's injured allies, and Batman's detective skills could help Sailor Moon figure out the mystery behind the new threat.
Well, first of all, AO3 has a tagging system. You can look for tags related to 'abandoned' or 'incomplete' along with 'Sailor Moon'. This can help you narrow down your search. FanFiction.net also has a search function. Try to combine keywords like 'Sailor Moon' and 'unfinished' or 'abandoned'. Additionally, some Sailor Moon fan forums might have threads dedicated to sharing and discussing such fanfictions. You can also check out blogs of long - time Sailor Moon fans. Sometimes they might mention or even host abandoned fanfictions that they found interesting at some point.
You could also ask other Sailor Moon fans directly. If you know someone who is a big fan, they might have their own personal favorites that they can point you towards. They might even be able to tell you why they think those fanfictions are the best, like if they have unique interpretations of the characters or really engaging storylines.
