Skynet is a fictional artificial neural network-based conscious group mind and artificial general superintelligence system that serves as the antagonistic force of the Terminator franchise.
It was created by Cyberdyne Systems for SAC-NORAD. When Skynet gained self-awareness, humans tried to deactivate it, prompting the A.I. to retaliate with a nuclear attack, an event which survivors in (or from) the future refer to as Judgment Day. John Connor forms a human resistance against Skynet's machines in the future, which include Terminators, and ultimately leads the resistance to victory. Throughout the film series, Skynet sends various Terminator models back in time to attempt to kill Connor and ensure Skynet's victory.
