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 common theme is friendship. Given that Discord has a complex personality and Luna is a princess, their friendship development is often explored. For example, how they learn to trust and rely on each other.
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 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.
Another theme is friendship. Even as a baby, Luna is shown forming bonds with other ponies or characters, like how she might interact with her sister Celestia in a more innocent and playful way. And these interactions help shape her future relationships. For example, in some fanfics, her early experiences with friendship teach her important values that she carries into her later life.
A common theme is friendship. Despite their different personalities, they often end up becoming friends in fanfics. Another theme is magic. Since both are associated with magic in the My Little Pony world, their magical abilities are often explored. For example, they might combine their magic to defeat a common enemy.
A common theme is identity. Since Luna is in a human form, she often has to grapple with who she is now compared to her pony self. Another theme is acceptance, both her accepting her new human form and the humans around her accepting this strange new being in their midst.
Redemption is a very common theme. Luna often has to prove herself after her return, making up for her past actions. For example, in many fanfics, she tries to regain the trust of the ponies in Equestria.
One common theme is friendship. Since Spike and Luna are from different parts of Equestrian society, their friendship can be explored in many ways. For example, how they bridge the gap between a young dragon and a princess of the night.
One common theme is the shattering of trust. When a character betrays in MLP fanfics, it usually breaks the trust that the other characters have in them. Another theme is the resulting chaos and confusion. For example, if a main character betrays the group, it can cause problems in their plans or the general harmony of Equestria. Also, the theme of redemption often comes up. The betraying character may later try to make amends for their actions.
Friendship is also a big theme. As with the overall My Little Pony franchise, fanfics often show Tempest forming new friendships and learning the value of it. For example, she might start off as a loner but gradually open up to other ponies.
