In MLP Nightmare Moon fanfics, the theme of forgiveness can be quite prominent. The other ponies in Equestria may have to decide whether to forgive Nightmare Moon for her past actions. And there's also the theme of self - discovery, as she discovers new aspects of herself during the course of the story.
One key theme is power. Many fanfics explore how Nightmare Star gains and wields her power, whether it's for domination or some other purpose. Another theme is redemption. Some stories focus on whether she can be redeemed or if she's truly beyond saving. Also, the theme of corruption often appears, showing how she was corrupted in the first place or how she corrupts others.
The themes of forgiveness and acceptance are quite common. Twilight may have to forgive Nightmare Moon for her past actions and accept her as she is or as she can be. Inversely, Nightmare Moon has to accept Twilight's offer of friendship. There's also the theme of self - discovery. Nightmare Moon might be on a path of self - discovery with Twilight guiding her, learning about her true nature and place in Equestria. And sometimes, there's a theme of facing a common enemy where they have to put aside their differences and work together using their unique magical abilities.
The fanfic could be unique in how it weaves the plot. Maybe it combines different story arcs from the My Little Pony universe in a new way. For instance, incorporating elements from different seasons or specials to create a fresh narrative around Nightmare Moon's return. Also, the use of unique writing styles, like a more poetic or dark tone, can set it apart from other fanfics.
Well, there's a fanfic that I really liked called 'Nightmare Moon's New Path'. In this story, she teams up with Twilight Sparkle to face a new threat to Equestria. It's interesting to see how their relationship develops throughout the story. There are also some fanfics that explore her relationship with the other princesses in a more in - depth way.
The contrast. Normally, Fluttershy is so gentle and timid. But in the nightmare versions, she becomes this powerful and often menacing figure. It's like seeing a completely different side of a well - loved character.
One common theme is self - discovery. When Rainbow Dash becomes an alicorn, she has to figure out who she is now. For example, in many fanfics, she struggles with the new powers and responsibilities. Another theme is friendship. Her friends play a big role in how she copes with the change. They support her or sometimes are a bit jealous at first but then come around.
One common theme is the struggle between good and evil. Since Nightmare Rarity is a darker version, there's often a battle within her or against other characters. Another theme is the power of friendship. Even in a fanfic about a villain - like character, friendship can play a role in her development. Also, the theme of transformation is common, whether it's her changing from Nightmare Rarity back to normal Rarity or evolving into something new.
One idea could be that the OC is a new pony in Equestria who has the ability to sense the lingering darkness of Nightmare Moon within Princess Luna. The OC could befriend Luna and help her fully come to terms with that part of her past, leading to a stronger and more confident Luna.
One popular 'Nightmare Moon x Human' fanfic is 'A Moonlit Encounter'. It has an interesting plot where the human character stumbles into the world of Nightmare Moon and they form an unexpected bond. The writing is quite engaging, with detailed descriptions of their interactions.
Well, the main element is obviously cuddling. It's about the physical closeness between the ponies. For example, in many fanfics, you'll see Twilight Sparkle cuddling with her friends when they're having a cozy study session or just relaxing.
