|This article is about a/an villain headquarters in Power Rangers Time Force.|
The Cryo Prison was used by Time Force to store captured Mutants. In the year 3000, Ransik used the prison to travel into the past and, once in the 21st century, used the prison as a base and gradually released all of the captured Mutants. The Cryo Prison remained undiscovered in the woods of Silver Hills.
Notacon was kept here for a time.
