The Booster Gold is Michael Jon Carter, and he was a famous Metropolis sportsman in the 25th century. However, he started betting on his own games and manipulating results in order to earn money for his mother's surgery. He was discovered and kicked out of sports. Rejected even by his own family, he ended up working at a superhero museum, where he learned about the heroes of our century. He daydreamed, thinking about how he could be a hero in our time. He then stole several of the museum's paraphernalia, and Rip Hunter's time machine. It had great importance in 52. Now, in this new version, he becomes a policeman of the time, taking care so that History is not changed. Rex, still mad at Rip, went to work secretly for the Time Stealers. He would go with the evil Supernova and try to change the past to make themselves the heroes. However, Booster and Rip stopped them and Rex was taken back to Rip's lab where he was tortured. Before Rex could tell Rip anything he was ripped out of the time stream. The Time Stealers had found out Rex's real name and gone back in time and killed him in his crib and made it as though he had never existed.In the second post-credits scene we'll find out that whoever Martian Manhunter was talking to in the post-credits scene of Batwoman was actually Booster Gold himself. Post-credits scene shows the Blue Beetle.
