are their any stories about changeling predators the reason being I was watching a anime recently about a vampire that fed off other vampires (I cant spell the name cause its in Japanese) so if there are any stories like that I would love to know

Trinity blood?

Is good anime/manga.

As for the predators concept, I have thought about it before but I have not seen any stories featuring the idea.

A pony-like carnivore that also can disguise itself as a regular pony would make for an interesting suspense antagonist.

isnt that what a changeling is? But in all seriousness yea it would be a good read

I did a mystery story based on this premise: Alone.
