Undertail (PACIFIST)

Once upon a time...

There were two species: Ponies and Equine Monsters.

Both species ruled over the land that the Humans once lived before they perished.

But one fateful day, the Ponies declared war on the Equine Monsters for no apparent reason.

In the end, the ponies were victorious.

Using the magic of their most powerful Unicorns, they trapped the Equine Monsters in another dimension.

Name the fallen pony:
