My Little Pony: Reborn as an Alicorn Foal

After a car accident, Xing Luorui transmigrates into Equestria and starts out as a young alicorn. She has the powerful bloodline of an alicorn, but can't even control her magic or fly.

All she wants is to join Twilight Sparkle and the M5, and live in peace surrounded by friendship and warmth.

But fate plays a deadly joke on her. Dark magic drags her away, and she falls into Shadow Valley, where she comes face-to-face with a host of villains.

To survive, she is forced to don a mask of evil and feign allegiance to Chrysalis, Cozy Glow, Tirek, and the other villains.

She is a double agent lurking in the darkness,

feeling her way through the villains' ranks while pretending to be an ambitious young pony who covets the throne;

in corners where no one can see, she learns to control her magic and gives everything she has to protect Equestria, and safeguard the friendship and peace of the M6.

She has never wanted to overthrow or hurt anyone. In these troubled times, she only wants to hold onto the line that separates light from darkness.

As the main plot of Season 9 kicks into high gear, the undercover foal's perilous adventure begins.

The author updates irregularly, only writing the parts they like, and will also add some bonus side stories. The cover shows what the protagonist looks like.

I couldn't find any Season 9 fanfiction or stories about young alicorns on many sites. There may not be much inspiration, but I'll do my bestヾ(๑╹ヮ╹๑)ﾉ”
