SCP-106, AKA the Old Man, is an extremely dangerous Keter-class creature currently under guard by The SCP Foundation. It appears to be an elderly humanoid at an advanced stage of decomposition. It remains in a dormant state for up to three months, simply waiting for its prey. When it awakens from this dormancy, it will attack and abduct any potential prey items, with a preference for humans aged 10 to 25.

In the event of an escape, the Foundation will use an individual from the above age bracket. When ready, a major bone or tendon will be damaged in some way and the screams of agony broadcast across the facility. Should 106 not respond within 10-15 minutes, further physical trauma will be applied every twenty minutes. In some cases, the Foundation has had to use multiple lure subjects to recapture it.


  • Rust touch: SCP-106 corrodes any solid surface it touches. The corrosion starts several seconds after the object in question comes into contact with 106 and ends roughly six hours later.
  • The Pocket Dimension: SCP-106 has access to its own pocket dimension in which SCP-106 seems to have complete control of time, space, and perception. It uses this dimension to move through walls and to trap prey. The dimension itself is known to be some kind of labyrinth, but little else has been discovered.
  • Phasing: SCP-106 can phase through almost any solid matter. Its cell is made of 40 layers of lead lined steel which he cannot walk through, meaning with the right and enough material, 106's phasing is limited. Complex construction seems to confuse him and slow him down.


  • SCP-106 appears as the secondary antagonist in the game SCP: Containment Breach. It has an invisible spawn countdown and will spawn next to the player when it ends, proceeding to chase the player. If it catches you, the player has a chance of being taken to the pocket dimension. Although very difficult, it is possible to escape, though this may cause wounds due to SCP-106's corrosion effects.
