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.
One major theme is the struggle between her old Equestrian life and her new human life. In many fanfics, Luna misses aspects of her pony existence like her connection to the moon in a different way. Also, the theme of discovery is quite common. She discovers new things about the human world, like technology or different cultures, which is really fascinating to explore in these stories.
Many MLP human Luna fanfics have a theme of friendship. Even though she's in a human form, Luna still forms bonds with others, whether it's with other humans or with characters who might also have a connection to Equestria. This friendship theme often shows how Luna can find common ground and support in this new and unfamiliar world.
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.
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.
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 the idea of acceptance. The human often has to be accepted by the pony society and vice versa in order for the romance to thrive. For example, in many fanfics, the human might be seen as an oddity at first but then is gradually embraced. Another theme is the discovery of new emotions. Since the human is in a different world, they might experience love in a way they never have before.
A frequent theme is the adaptation to a new physical form. The characters may have different physical abilities or appearances due to the gender change. This can lead to interesting plot developments, like a character having to learn new ways to move or present themselves. Also, power dynamics within the group can change, as different genders are often associated with different levels of social power in society, and this is often explored in these fanfics.
Well, in these types of fanfics, a recurring theme is the concept of the 'other'. The human baby is the 'other' in the MLP world. So, there's often a theme of acceptance. The ponies have to accept this strange new being into their world. Another theme can be family. Even though it's a human baby in a pony world, there can be a sense of family created, whether it's the ponies acting as a surrogate family or the baby bringing out a family - like bond among the ponies. There may also be themes related to the baby's influence on the pony society, like how the ponies' values or way of life might change because of the baby's presence.
One common theme could be the battle between light and dark. Luna represents the moon and has an association with the night, which can be seen as a time of mystery and sometimes danger. King Sombra is a dark character. So the fanfic may explore this contrast in terms of their powers and personalities.
One common theme is friendship. Just like in the original My Little Pony, friendship is a central aspect. The human versions of the characters form bonds and face challenges together. Another theme is the adaptation to a new world. Since they are in the human world now, they have to adapt to human customs and society.
School events also play a big role. Proms, football games, and school plays are often part of the story. These events create opportunities for drama, romance, and character development. For example, at the prom, there could be a big reveal or a romantic moment between two characters.
