As long as I can siphon off the Speed Force, you can't escape this timeline. I'm afraid there just isn't enough Speed Force to go around.
Who: Professor Zoom
Source: Justice League: The Flashpoint Paradox
Note: While mocking the Flash, Zoom says these words before Thomas Wayne/Batman kills him by shotting his head, allowing Barry to use Speed Force to travel back in time. Zoom's fate might have been reverted by the creation of the new timeline, or perhaps he was erased from history.
