The
T-3000 is a fictional cyborg assassin, serving as the primary antagonist in
Terminator Genisys, the fifth installment in the
Terminator series, portrayed by
Jason Clarke. T-3000 also serves as a
foil personality to "Guardian" (a reprogrammed
T-800 portrayed by
Arnold Schwarzenegger), a protagonist who is somewhat similar to T-3000 but also opposite in many ways. In the film, the T-3000 is an alternate counterpart of
Skynet's (portrayed by
Matt Smith) nemesis
John Connor, created after Skynet fractures the timeline.
