Taking a first look at The Flash: Rebirth is pretty much a direct follow up to DC Universe Rebirth and of course focuses on Barry Allen. It seems though, that some of the events in this issue happen before Barry meets up with Wally. We kinda see a greatest hits of Barry’s life as Flash with coverage of his origin, some of his fights against Zoom, his family life, and then we land on the Rebirth event. Barry pulls Wally out of the Speed Force and we learn that some outside force has stolen time and relationships from the universe.
It’s a pretty good issue with an introduction to Flash and seems to act as a bridge from the 52 era to the future story.
