CY-CLOMPS is a military supercomputer from the episode “The Big Rip-Off” in the 1987 TV series. It was located at Fort Charles, and operated dozens of drone robots and other dangerous computerized devices. Its function was to protect a trilithium crystal in the vault.
Unfortunately, Shredder successfully hacked CY-CLOMPS and caused it to eject all humans from the base. The Turtles were able to infiltrate the base, and Donatello reprogrammed and shut down CY-CLOMPS.
