The theme of redemption can also be present. If Supernova is initially a character with some flaws or has made mistakes in the past, the fanfic might show how Luna helps Supernova to redeem themselves. This can create a deep and meaningful story arc, as Supernova grows and changes throughout the course of the fanfic.
One great MLP Luna and Supernova fanfic is 'Luna's Encounter with Supernova'. It shows how Luna meets Supernova in a magical forest and they embark on an adventure to save the enchanted creatures there. The story has vivid descriptions of the settings and the characters' emotions are well - portrayed.
Another theme is self - discovery. The OC usually has some sort of journey where they learn more about themselves, and Luna also often discovers new aspects of her personality or her role in Equestria through her interactions with the OC. For example, in some fanfictions, Luna realizes she can be more approachable through her time with the OC.
Another theme is redemption and guidance. Luna has a past she's trying to overcome, and in many fanfics, she helps the reader while also finding her own path to redemption. It's about two characters growing together in different ways. For example, in some stories, the reader might be lost in Equestria and Luna guides them, while at the same time, the reader's presence helps Luna face her inner demons.
Friendship is a very common theme. Since Twilight and Luna are both important characters in MLP, their friendship is often explored, like how they support each other through different challenges.
One common theme is friendship. Given that they are two characters in the MLP world, their relationship often showcases the power of friendship. Another theme is magic, as both characters are associated with celestial and magical elements in the MLP lore.
Luna, with her connection to the moon and her magic related to the night. And Supernova, who could be a pony from a far - off land or even a new creation within the fanfiction world. They are likely to be at the center of the story, driving the plot forward with their actions and interactions. For example, their different personalities might clash at first, but then they learn to work together as the story progresses.
One interesting storyline could be Luna and Supernova teaming up to save Equestria from a new and powerful dark force. They might use their combined magic to overcome the threat.
One idea could be a story where Luna and Sombra meet in a dream realm. Luna, being the princess of the night, has the power to traverse dreams. Sombra, once a powerful and dark figure, could be lost in this dream realm. Luna tries to understand his past and help him find redemption. It could explore themes of forgiveness and the power of understanding.
