Human Prisoner 1 was a Human who served in the United Nations army during the early stages of the Machine War. He would eventually be captured by the Machines along with numerous other humans in order to be experimented on, potentially, as a new source of power for the Machine race.
History[]
At some point this human would volunteer to fight the Machines during the Machine War.
Machine War and Capture[]
At the very early courses of the Machine War, this soldier was captured by the Machines. His clothing was then removed and all his hair shaved off before getting kept in a semi-conscious state to be experimented on by the Machines.
The soldier was picked up and prodded by a Sentinel while his skull was left cut open with his brain exposed; laughing, moaning horrifyingly, and helplessly reacting to the electric currents directly delivered into his brain during the Machine experimentation. His fate after this is unknown. It is possible he was plugged into a pod and then assimilated into the first Matrix.
