A ponified verson of my demon dog species Wreen [link] Redrawn for a rp.

These are nasty creatures that come in three different forms, just like there are different pony species. They have a nasty temper and live of pony flesh, this includes ponies that have been dead for some time. But they are also smart and while they want to live in Euquestria they don’t want to take over by their own. Instead they prefer to let someone other do the dirtywork and come in like stray dogs or similar, living off what is left, like dead bodies or turn other ponies into new Wreen. They all have similar manes, the leaders have longer mane in the back of their head. Also unlike ponies they don’t have a hair tail but rather a snake tail.
Also…none of the wreen have a cutiemark. When they turn their special abilites are consumed by the demon power and turned black, just like their fur.

Earth pony wreen - just like a normal Earth pony but black fur etc

Unicorn wreen - They have two horns instead of one and can’t use magic. But magic doesn’t affect them either.

Pegasus wreen - Faster than the others and instead of wings they have spikes on their sides.
