Twilight Sparkle is a beloved character, so a death fanfiction would likely be quite controversial. However, it could also be a creative way to re - imagine the story. For example, her death could lead to a new villain emerging or a different power structure within the Equestria setting. It all depends on the author's intentions and how they choose to handle such a significant event.
One aspect that makes it unique is the emotional impact. Twilight is a central character, so her death would shake up the whole story. It's different from minor character deaths.
In some fanfictions, she could die sacrificing herself for her friends. Twilight is extremely loyal to her friends in Ponyville. So, if there was a situation where her friends' lives were in danger, like from a powerful villain, she might choose to give up her own life to protect them. This would be a very heroic and in - character way for her to die.
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.
One possible theme could be sacrifice. Maybe Twilight Sparkle sacrifices herself to save her friends or Equestria. Another theme might be dealing with grief among the other ponies after her death.
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.
I really don't think it's a good idea to focus on 'twilight sparkle death fanfic'. The 'My Little Pony' franchise is mainly about friendship, magic, and positive values. Reading such dark fanfics might not give you the best experience. Instead, you could look for fanfics that show Twilight Sparkle's journey in learning new spells or making new friends in Equestria.
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.
Fanfiction about Twilight Sparkle being banished can also be a vehicle for exploring different relationships. Maybe she meets characters she would never have interacted with in the show. Her banishment could bring out different sides of her personality. She might become more resourceful or develop a stronger sense of self - reliance as she tries to navigate her new situation.
One great 'Twilight Sparkle Fanfiction' is 'A Magical Friendship'. It really delves into Twilight's growth in magic while also strengthening her bonds with her friends. The story has a lot of interesting plot twists and the characterizations are on point.
