It can have a strong emotional impact. Fans who are attached to Twilight Sparkle will feel sad. Some might even be angry if they think the death was unjust or not well - written. For example, if her death seems too sudden and without proper build - up in the story.
One example could be a story where Twilight Sparkle sacrifices herself to save Equestria from a powerful dark magic. Maybe she uses all her magic energy to create a shield that stops an evil force but in the process, it drains her life completely. Another could be a story of an incurable illness in Equestria that Twilight contracts and despite the efforts of her friends, she succumbs to it.
On one hand, it can add depth to the fandom. Fanfics about her death can explore complex emotions and situations that might not be covered in the main series. It can make fans think more about the characters and their relationships. However, it can also be controversial. Some fans might not like the idea of Twilight dying at all and could feel that it goes against the spirit of the show.
No, it's not that common. Most 'My Little Pony' fanfictions tend to focus on positive aspects like friendship, adventures, and character development. Torturing a beloved character like Twilight Sparkle goes against the general upbeat and friendly nature of the fandom.
The main difference is the 'insane' factor. Regular fanfiction might focus on Twilight's normal day - to - day adventures, like studying magic or helping her friends with normal problems. But 'insane twilight sparkle fanfiction' will likely take her into more extreme situations, like having a mental breakdown due to magical overload or some other crazy event.
These fanfictions can spark discussions within the fandom. People might debate about how in - character or out - of - character the betrayal is. Some fans might create their own versions of how the story should continue after the betrayal, which in turn enriches the overall fan - created content in the My Little Pony community. Moreover, it can attract new fans who are interested in exploring the darker or more complex aspects of the MLP world.
A likely candidate could be Discord. He is known for causing chaos and mischief. He might pretend to befriend Twilight Sparkle only to betray her at a crucial moment. Another possibility is Trixie. Trixie has been jealous of Twilight in the past and could betray her out of envy.
Flash Sentry could be a likely groom. He has shown an interest in Twilight in the past and they have had some interactions that could lead to a romantic relationship. Another option could be a completely new character, perhaps a powerful wizard or a prince from a far - off land who Twilight meets during one of her adventures and falls in love with.
In the fanfiction, Twilight Sparkle giving birth could bring about a more unified Equestria. The foal could be a symbol that brings all the different pony tribes closer together. Also, the new life might inspire new laws or ways of living in Equestria. Maybe there will be more focus on education and nurturing the young with Twilight as a role model for motherhood. It could also lead to new magical discoveries as the foal grows and shows its unique powers.
One possible fanfiction could involve Twilight Sparkle's dragon transformation being a result of a powerful magic spell gone wrong. She might struggle to control her new dragon form and powers at first. For example, she could accidentally set things on fire when she tries to use her magic in her dragon state. As the story progresses, she learns to master her new form through the help of her friends.
I'm not entirely sure specifically as it could refer to many different fan - created stories about Twilight Sparkle that have been forgotten. It might be a fanfic that was once popular but has since faded from the spotlight, perhaps due to new trends in the fandom or simply being lost among the vast number of fanfics out there.
