A throwaway line in Generations Shattered #1, out today from DC writers Dan Jurgens, Andy Schmidt, and Robert Venditti with a murderer’s row of star artists, may have revealed an interesting new world in DC’s post-Rebirth multiverse…and one that has a kind of off-kilter connection to Doomsday Clock. In that series, Doctor Manhattan traveled from the world of Watchmen to the DC Universe, and was keenly aware of the rolling timeline that keeps all of the heroes young and vibrant while decades pass in the “real” world. There, he watched Superman’s first appearance on Earth moving from 1938 to 1985 to 1999, and so on.
