Notes
- The events of "The Garden of Mercy" storyline take place in the paradoxical timeline of Earth 0, which was born as a consequence of the fracture of Hypertime, where multiple events across the DC Universe happen at the same time.
- These events will be eventually merged into the main timeline after the rebirth of Creation in the epilogue of the last Metal War.
- The issue references Superman's dreams in Superman Annual #11.
- Reprinted in Justice League: Galaxy of Terrors.
