The Nobodies are those weird monkey/man amalgamations you encounter in the demon world in DMC1. They're gray and red. They look like monsters from Resident Evil, undoubtedly remnants of the game's original concept.
As for the topic, I'd like to see more elements from the original mythology. Lady, specifically, but some demons, like Phantom or Beowulf, would be interesting.
