In 2008, ten years after the crossover, an issue of Booster Gold (vol. 2) was published as "Booster Gold #1,000,000", and was announced as an official DC One Million tie-in by DC Comics. This comic introduced Peter Platinum, the Booster Gold of the 853rd century.
Grant Morrison's All-Star Superman limited series made several references to the DC One Million mini-series. The Superman from One Million makes an appearance and the series ends with Superman becoming an energy being who resides in the Sun after his body has been supercharged with yellow solar energy (similar in appearance to Superman Prime), and Solaris makes an appearance as well.
Morrison's Batman #700 also briefly shows the One Million-era Batman and his sidekick—Robin, the Toy Wonder—alongside a number of future iterations of Batman.
The One Million Batman, Robin and Superman play a significant role in Superman/Batman #79–80, in which Epoch battles Batmen and Supermen from various time periods.
