Violating the human free will Agents exhibit the ability to Possess the RSI of any software still plugged into their hardware. When they finish borrowing the RSI, the host has no recollection of what happened while the Agent was using their body. The range of Possession is unknown but it travels considerable distance in The Matrix. Possession seems to take a little while, it is not instantaneous. It also grants Agents a sort of immortality as long as there are people plugged into the Matrix. The machines are not omniscient, so it may take a while for an Agent to decide upon a host to Possess. Finally, there is no reason to believe that Agents suffer from reduced abilities based upon the host they choose to Possess.
