Technically, Nightmare Moon, or just Nightmare I guess she is when she's not possessing Luna or Rarity, is the Nightmare Forces. Larry and the others were corrupted by Nightmare's dark power, but to have a physical form, Nightmare must possess a pony, which, like angels on Supernatural, she can't do unless they let her in so she has to manipulate them into it
