Speeding through Central City, Barry Allen is met with a startling sight--the Flash, older, battered, and badly injured. Before he can speak, the doppelg nger is gone.

Then Barry begins experiencing glitches in his powers--moments that leave him ghostly and immobile in the middle of missions. When a group of his enemies--including Pied Piper, Weather Wizard, and Peekaboo--chooses this time to launch a new assault, the Flash seeks help from his most trusted ally.
Oliver Queen - the Arrow.
