The "Demon Planet" is the setting of chapter 13 of Samus and Joey. It is located far from Diesel's station and is used by the Dominion, a nefarious organization known for controlling wars from the shadows using deadly weapons. Diesel and Joey Apronika are captured and brought here to be used in an experiment with Hunter-Killers and a Samus Tank, robots made in Samus Aran's image. The real Samus appears and destroys the robots with a Power Bomb, her Shinespark and her Screw Attack. The three of them remain behind and encounter Integra.

From the outside, the planet resembles a skeleton's face, bearing similarities to Jack Skellington from The Nightmare Before Christmas. The environment is described by Joey as "burning rocks and barren sand".
