Professor Zoom could be referring to what Zoom (The 2nd Reversed flash) Could do with Time Travel and what not but I some how doubt it.
Quote:I don't think so, since the Black Flash presumably died, to be replaced by Barry - and Zoom seems alive, though apparently trapped in the Speed Force. But speedsters can travel time, so maybe you're right, somehow.
Quote:What do you think Zoom meant by his statement that he has thrown Barry into reverse?
Final Crisis and Rebirth have also seemingly indicated that the Black Flash is either identical to or connected with the Black Racer of the New Gods, who traditionally needs a human host like Willie Lincoln.
