Question regarding possible characters for someone...<br/><br/>Can we have this universe be one in which<em>The Killing Joke</em>either never happened (Like<em>The Long Halloween</em>, that storyline was never meant to be canon to the mainstream DCU) or Barbara was cured somehow?  Honestly, with all the super geniuses in the DCU, I have no doubt that someone could restore her to the way she was before.  She was a lot better as Batgirl than Oracle in my opinion.
