SYS_ADMIN is a representation of an internal process in Claptrap's mind, in the Claptastic Voyage DLC from Borderlands: The Pre-Sequel. It resides in The Nexus, and is presumably the central controller which runs Claptrap's operating system. It manifests as a very large Claptrap unit with six arms.


SYS_ADMIN only interacts with the Vault Hunters during the mission Enter the Claptrap, when it revokes Handsome Jack's admin password because the Vault Hunters attempt to retrieve the H-Source. Otherwise, SYS_ADMIN merely goes about its business of running Claptrap's OS.
