The T-X Terminator is an advanced type of Terminiator designed in the future by Skynet to fight against the human resistance. After the success of the mimetic polyglot T-1000 Terminator, Skynet began to make new models combined with a metal endoskeleton and liquid metal. They are fast, smart and very deadly. Unlike other models, the T-X shows pleasure in killing and it also shows fear. One unit was sent back in time to the past on a mission to kill the leader of the future resistance, John Connor and his future officers. It failed in its mission and was killed by an older reprogrammed Series 800 Terminiator whose mission was to save John, destroyed it and itself in the end.
