ZDR is a remote robot-infested planet and the setting of Metroid Dread. A mysterious transmission from an unknown source is received by the Galactic Federation and traced to this planet. The message indicated that the X Parasites had not been entirely destroyed 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 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.

She’ll encounter strange new life forms, radically different environments, and the rogue E.M.M.I. of course, as she explores the planet’s hidden secrets and takes on her mission." 16 June 2021 11:25 a.m. Tweet. https://twitter.com/NintendoAmerica/status/1405184665481269251
