T-800, able to match its strength due to his own metal endoskeleton, but due to Marcus harbouring biological organs, specifically his human heart, the T-800 is able to incapacitate him long enough to stab John through the abdomen from behind, wounding him. Marcus retaliates by jamming the same metal bar through the T-800's neck and twisting it until its head rips off, destroying it instantly. The hydrogen fuel cells are set off as John and Marcus escape, destroying the base and a number of unfinished T-800s with it. Terminator Genisys (2015) In Terminator Genisys, a T-800 was reprogrammed by an unknown party from a point in time further in the future, and sent to 1973 to protect nine-year-old Sarah Connor (Emilia Clarke) from a T-1000 sent to kill her and her parents. After her parents are killed, the T-800 becomes her surrogate father and raises her to prepare for her future destiny, similar to the relationship between its doppelgänger and the young John Connor in Terminator 2: Judgment Day. The T-800, which Sarah refers to as "Pops", has experienced an unprecedented level of emotional development, to the extent that it keeps her childhood drawings and photographs. In the film, it is speculated that the knowledge of who sent Pops back was deliberately erased from its memory so that Skynet (Matt Smith) could not track them down later.

After Kyle Reese's (Jai Courtney) arrival in 1984, the trio defeat the T-1000 (Lee Byung-hun) together. Later, in 2017, they battle John Connor (Jason Clarke), who has been transformed into a T-3000 tasked to ensure Skynet's rise. After multiple confrontations, Pops attempts to sacrifice itself to destroy the T-3000, telling Kyle Reese to "protect [his] Sarah". However, during the battle, Pops is thrown into a vat of mimetic polyalloy before the T-3000's defeat, and as a result gains shapeshifting abilities similar to the T-1000, as well as repairing earlier damage such as its lost left arm. Pops gives its
