Proboscum as it appears in Metroid II.

The Proboscum is a harmless, invulnerable robotic drone found on SR388. There is much speculation over its original purpose, as it is typically found malfunctioning and clamped onto a vertical wall, where its swivelling arm can be used as a platform. However, it will continuously flick down, so Samus must be quick.

Metroid II manualEdit

"Originally programmed as a worker, not a fighter, this robot is out of order and out of control."


  • If Samus tries to use the Spider Ball to climb the Proboscum, the screen will shake violently until the Proboscum flicks down.
  • Proboscum do not appear in Metroid: Samus Returns.
