Guards are the security programs loyal to Sark and the MCP in the computer world. It is assumed that ICPs are the updated versions of Guards.

They use long wand-like staffs as weapons to stun programs and also to block attacks. These staff weapons are similar to rod weaponry but are different. It seems they don't use their identity disks as weapons.

It is currently unknown what happened to the remaining guards after Tron defeated the MCP; they most likely returned to being normal guards, working for their users and protecting the system from viruses.
