The dark pony guard called Painkiller is kinda hard to get along with. He treats his enemies bad, and treats his friends worse. He does have a rather special talent however, one that he uses to both amuse himself, and sometimes help his Princess.

If your best friend found a book called 'The Art of the Sub' in their honest, kind and friendly sisters room and suggested they should read it, would you?

An alien, and mysterious creature has appeared suddenly in Ponyville. He claims to be harmless, but there is something dark, and foreboding about him

On Earth, he had many names. Murderer, killer, assassin. These were just a few he clung to. Here, in this world though. His title is Guardsmen. His Goddess in of the Moon itself. He will do whatever it takes to ensure her safety. Anything.
