Power and responsibility are often explored. Since Queen Serenity has great power, the OC might be learning about the responsibilities that come with power, just like the Sailor Scouts do. Also, the theme of sacrifice can be present. Queen Serenity is known for her great sacrifice, and the OC might be faced with similar situations where they have to make difficult choices for the greater good. Additionally, the idea of destiny is common. The OC may be trying to figure out their place in the grand scheme of things in the Sailor Moon world which is often guided by destiny.
Sure. You can try looking on fanfic websites like Fanfiction.net or Archive of Our Own. Just search for 'Sailor Moon Queen Serenity OC' and you'll find a variety of fanfics. Some might focus on an original character's relationship with Queen Serenity, while others could be about the OC's adventures in the Sailor Moon universe.
One common theme is self - discovery. The OC daughters often start out not fully aware of their powers or their place in the Sailor Moon universe, and the story follows their journey to figure these things out. For example, they might discover they have a special connection to a certain Sailor Scout.
Friendship is a big theme too. Characters from different universes in Sailor Moon crossover fanfic often become friends and learn from each other. They support each other in battles and in personal growth. Also, the theme of saving multiple universes is quite common. Since it's a crossover, there are usually threats that endanger both the Sailor Moon universe and the other crossed - over universe.
Love and friendship are also big themes. Yaten may initially be cold or distant, but as he gets to know the OC, a bond of love or deep friendship forms. It's like in the fanfic 'Yaten's New Connection' where the OC's kindness slowly melts Yaten's tough exterior and they become close friends who might be on the verge of more.
Power struggle is a common theme. The OC Queen often has to fight for her position and authority against other powerful groups or individuals in the post - apocalyptic setting.
Power is a big theme. The powers of the Sailor Scouts, which are based on elements like the moon and stars, are different from the vampiric powers in Vampire Knight. In crossover fics, there's often a comparison or a combination of these powers. Also, the idea of good vs evil is common. Sailor Moon and her friends are the defenders of love and justice, while vampires in Vampire Knight are often seen as more morally ambiguous. So seeing how they interact in the face of threats is a theme. Sometimes, there's also the theme of transformation. Both series have elements of transformation, and in crossovers, it can be interesting to see how the two types of transformations interact.
A great concept for a Sailor Moon OC fanfic is an OC that has a special connection to the moon but not in the same way as Sailor Moon. This OC could have been created by an ancient civilization on the moon to be a protector. She might have different abilities like being able to control lunar phases for various effects, such as using a new moon to create a shield or a full moon to enhance her strength. Or an OC who is an artist, and she uses her art to fight the evil. Every time she draws something, it comes to life to battle the bad guys.
One common theme is the combination of different magical systems. For example, mixing Sailor Moon's lunar magic with other supernatural powers like witchcraft or demon magic. Another theme is the exploration of alternate universes where Sailor Moon characters interact with a wider range of supernatural beings.
One common theme is power combination. Writers often explore how the powers of Sailor Moon characters combine with those from the other crossover universe. For example, in a Sailor Moon and Dragon Ball Z crossover, they might look at how Sailor Moon's magic could work with the energy - based attacks in Dragon Ball Z.
The theme of self - discovery can be found in'meet Sailor Moon' fanfictions too. When a character meets Sailor Moon, they might start to discover their own hidden powers or their true purpose in life. This often ties in with Sailor Moon's message of empowerment and finding one's inner strength.
