Who could be the main antagonist in a 'human becomes twilight mlp fanfiction'?

Well, perhaps the human could be transported into the My Little Pony world and gradually take on the characteristics of Twilight. Maybe they start by learning magic like Twilight does, and as they do, they become more like her in personality too, like becoming more studious and dedicated to knowledge.

It could be a vampire who resents Damon for becoming human. This vampire might see it as a betrayal of their kind. They could try to either turn Damon back into a vampire against his will or simply make his human life miserable.

The main antagonist could be a dragon hunter. Since Saphira is now in a human form and has lost her dragon defenses, the hunter sees her as an easy target. He might be after her because he believes that she has some connection to the dragons and he wants to use her to find the dragon lair or something valuable related to dragons.

It could be another ghost who is jealous of Casper's new human form. This ghost might try to sabotage Casper's attempts to fit into the human world, perhaps by causing chaos around him and making humans afraid of him again.

A powerful witch could be the antagonist. She might have been the one who turned Damon human again against his will, and now she has some sinister plan for him. For example, she wants to use his new human form to perform some dark magic ritual that requires a human with a vampire past.

Another possibility is that one of Twilight's own insecurities or fears takes on a form and becomes the main antagonist. It drives her to betray her friends as it convinces her that the Mane 6 are not as good as she once thought.

Another theme is friendship. Just like in the original My Little Pony series, Twilight forms a bond with the human character. They support each other through various challenges, whether it's Twilight helping the human understand a magical problem or the human helping Twilight with a non - magical issue in their world.

Her friends like Pinkie Pie, Rainbow Dash, Applejack, Rarity and Fluttershy are likely to be main characters. Pinkie Pie might bring her usual cheer and parties to celebrate Twilight's new form. Rainbow Dash could be both impressed and a bit competitive, trying to keep up with Twilight's new abilities in her own way. Applejack would offer her down - to - earth advice and support. Rarity might be excited to create new outfits for Twilight as an alicorn. And Fluttershy would be there with her gentle nature, providing a calming presence.

There's also 'Twilight and the Human Scholar'. In this fanfiction, Twilight meets a human scholar who is interested in Equestrian magic. Their relationship grows as they exchange knowledge, and it delves into how their different worlds' cultures and magics interact.

Obviously, Twilight is one of the main characters. And the other main character seems to be the 'me' in the title, which could be a self - inserted character created by the author, perhaps someone who enters the My Little Pony world and has a special connection with Twilight.
