Demon Planet

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 an unknown organization 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.

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".
