The firm's co-publisher Dan DiDio told Digital Spy that he felt the title's characters were being overused, and chose to "rest" them for the time being.

He said: "It was selling okay, but we had greater expectations for that line. There's a lot of those characters that I feel we've told a lot of stories with, so at this particular moment we'll give the title a rest, and maybe give some of those characters a rest."
