Booster Gold; The Flash [Barry Allen]; Doomsday; General Nathaniel Adam; Alexandra Gianopoulos; Batman [Thomas Wayne] (cameo); Kal [Subject One] (cameo); Goldstar [Michelle Carter] (cameo); Rip Carter (cameo)
Having brought Booster in for questioning, General Adam tries to force a confession out of the hero, but in doing so he gives up control over Doomsday. When Doomsday spots Kal on a monitor, he goes into a rampage which only ends when Alex puts on the control helmet and forces the monster to kill himself. Now aware that Flash is in England, Booster and Alex head there to harness the chronal energy of Flash's speed force so Booster can jump into the timestream and set things right. Re-powered, Booster travels to Vanishing Point, but with no memory of the alternate timeline.
