Notes
- Beginning with this issue, the Action Comics series starts a short period where the Superman of Earth-One (and all his supporting characters and villains) exist on the post-Crisis New Earth. This period ends when the effects of the Crisis "catches up" with Superman (et al) in The Man of Steel #1.
- It is unclear why the Crisis did not affect Superman immediately. At the time there were several powerful beings who were trying to delay, reverse or control the effects of Crisis (including Mekanique, Aphrodite and the Infinite Man), and perhaps this was a side-effect.
