High Quality Content by WIKIPEDIA articles! Agents are a group of characters in the Matrix series. They are sentient computer programs, displaying high-level Artificial Intelligence, and are representatives, or "Agents", of the main antagonists within the Matrix fictional universe. They are guardians within the computer-generated world of the Matrix. Something akin to the anti-virus of the Matrix, guarding 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 collective. They appear physically human, but have a tendency to speak and act in highly precise and mechanical ways.
