According to Volume 8 of the Metroid Dread Report, ZDR shares similar planetary conditions, including temperature, humidity, gravity and atmosphere, with SR388. Although Sounds of Dread implied that ZDR was the original homeworld for the Chozo, Quiet Robe only refers to it as the homeworld of the Mawkin tribe of Chozo.
Previously unexplored by humans, a mysterious video transmission from an unknown source is received by the Galactic Federation and traced to ZDR. The message shows an X Parasite, suggesting they had not been entirely eradicated when Samus Aran crashed the BSL Station into SR388. The Federation sends a team of E.M.M.I. robots to investigate and loses contact with them. Samus, who has immunity to the X Parasites due to her Metroid vaccination, travels to ZDR to confirm for herself if the X have survived.
ZDR was ultimately destroyed after Samus and Raven Beak's battle.

- "Planet ZDR is home to many secrets and dangers. Get a glimpse at some of the hazards standing between Samus and the surface as she escapes the deadly depths of the planet."
- FIERCE FAUNA
- "The planet’s native species can be deadly. Stay on your toes to stay alive."
- ZDR is the second planet to have a purple atmosphere in the Metroid series, preceded by Dark Aether.
- In astrobiology, the purple Earth hypothesis posits that early life forms on Earth were retinal-based, rather than chlorophyll-based, making Earth appear purple. This hypothesis may provide insight for potential life on exoplanets. Interestingly enough, alien life roams freely on ZDR.
- How and why ZDR was destroyed is unclear. Though since its self-destruction began immediately after the death of Raven Beak X, it can be assumed that Raven Beak rigged the planet to explode upon his death as a fail-safe.
