One possible plot could be that Spider - Man gets transported to Equestria. Twilight Sparkle discovers him and is initially cautious but then realizes he has good intentions. They team up to fight a new threat that is causing chaos in Equestria, perhaps a villain who has the power to manipulate magic and technology in a dangerous way.
A combination of Green Goblin and a chaos - causing creature from Equestria. The Green Goblin could team up with this creature and use his glider and bombs along with the creature's ability to spread chaos. They would target both Spider - Man's city and Twilight Sparkle's home, causing destruction and trying to assert their control.
One idea could be that Spiderman gets transported to Equestria where he meets Twilight Sparkle. They could team up to stop a new villain that is causing chaos in both the human world and Equestria, perhaps a villain who has the power to open portals between the two worlds and is using it to steal valuable things from both. Twilight could use her magic to help Spiderman understand the new world he's in, and Spiderman could use his combat skills to protect Twilight when they are in dangerous situations.
There's a fanfic called 'Oc's Adventure with Twilight'. It shows the OC and Twilight going on a journey through different parts of Equestria.

There are several common themes in 'twilight sparkle x luna fanfic'. Unity is one of them. Fans like to write about how these two very different characters can come together and be a united force. Another theme is the exploration of their different personalities. Twilight Sparkle is often seen as the studious and rule - following type, while Luna has her own unique, more mysterious and regal personality. Fanfics may explore how these personalities interact and complement each other, leading to interesting character dynamics and storylines.
Often, these fics focus on their friendship growth. They might start with a small incident that tests their bond, like in 'pinkie pie x twilight sparkle fanfic' where they have an argument over a magic spell gone wrong. Then, through communication and understanding, they strengthen their relationship. It also shows how they influence each other. Maybe Twilight becomes more relaxed because of Pinkie, or Pinkie becomes more organized due to Twilight.
Romance is also a popular theme. Writers explore the relationship between the two ponies in a romantic light. This could involve them realizing their feelings for each other gradually or in a more sudden, 'love - at - first - sight' kind of way.
The appropriateness of a 'twilight sparkle diaper fanfic' is highly subjective. Some people might find it completely inappropriate due to the rather strange and unorthodox combination of the character and the diaper concept.

But overall, it's not a type of fanfic that would be considered appropriate for a wide - ranging and diverse audience.
An 'evil twilight sparkle fanfic' is simply a fan - made fictional story where Twilight Sparkle is portrayed as an evil character.

Maybe it begins in Equestria. Twilight Sparkle is doing some research in the library when she discovers a strange spell. When she casts it, a portal opens and Spiderman comes tumbling through. He's disoriented but quickly realizes he's in a very different place, and Twilight is equally surprised to see this strange human - like creature with such unique abilities.
