Booster Gold is an anomaly himself - a man from the future traveling through time and space to set things right as best he can. Now, as he returns to the present-day of the DC Earth, he finds things have changed drastically, thanks to the nefarious misdeeds of Eobard Thawne, the Reverse Flash.
As we see in the preview below, he's certainly not recognized as a friendly in this new alternate reality, and Booster's going to be on the run from a paranoid American military, mistaken for an Atlantean invader. There's also bad news in the offing for Skeets, as well as an ugly future for Michael Jon Carter as he's forced to square off against Doomsday on his own.
Check out these preview pages from Booster Gold #44, from writer/artist Dan Jurgens.
