The T-3000 is a fictional character and the central antagonist of Terminator Genisys, the fifth installment in the Terminator series, portrayed by Jason Clarke. In the film, the T-3000 is an alternate timeline counterpart of Skynet's (portrayed by Matt Smith) nemesis John Connor (also portrayed by Clarke), created after Skynet infects a variant of Connor with nanotechnology and fractures the timeline. The 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 the T-3000 but also opposite in many ways, of their relationship dynamics with Sarah Connor (portrayed by Emilia Clarke) and Kyle Reese (portrayed by Jai Courtney). The T-3000's sole mission is to protect and ensure the ultimate survival of Skynet, which seeks to eliminate the human race with its global machine network. The T-3000 describes itself as neither machine nor human; rather, it is a hybrid nanotechnological cyborg. Producer David Ellison explains that the title Terminator Genisys "[is] in reference to genesis, which is in reference to the singularity and the man-machine hybrid that John Connor ends up being." The T-3000 returns in the 2017 video game Terminator Genisys: Future War, a direct sequel to Genisys produced following the cancellation of the film's planned sequels in favor of another alternate timeline-set sequel, Terminator: Dark Fate (2019). John Connor In a desperate effort to ensure its survival, the rogue artificial intelligence Skynet creates an avatar for itself in the form of a T-5000 (Matt Smith). This Terminator travels through many timelines searching for a way to defeat the Human Resistance and ultimately infiltrates it under the guise of a fighter named Alex. "Alex" is present as a soldier when John Connor and Kyle Reese (Jai Courtney) discover Skynet's time machine at the end of the war with the machines. As Kyle is being sent back in time to protect John's mother Sarah Connor (Emilia Clarke) from the T-800 Terminator sent to kill her in 1984, "Alex" carries out his attack.
