Agents are a group of characters in the fictional universe of The Matrix franchise. They are guardians within the computer-generated world of the Matrix, protecting it from anyone or anything (most often Redpills) that could reveal it as a false reality or threaten it in any other way. Agents also hunt down and terminate any rogue programs, such as The Keymaker, which no longer serve a purpose to the overall Machine objective. They are sentient computer programs disguised as human.
