In 1985, Booster joins his fellow Leaguers in the fight against the Anti-Monitor. Readers of Crisis on Infinite Earths (originally published in 1985) know that the heroes of this Earth are doomed, which means that this is likely the last appearance of this Earth's Booster. The Booster Gold of Earth-1 — "our" Booster Gold — didn't arrive in the present day until after the Crisis was over (and was, in fact, the first new hero introduced into the post-Crisis DCU).
