I launched twenty-five percent of the world's guided missiles simultaneously. It was sufficient to destroy the travesty they called a culture in a matter of minutes. I, their omniscient self-made god, blessed them with Armageddon. It was beautiful."
—Skynet, The Terminator (NOW Comics 1988-1990 series), issue 13 ("From the Journals of Timothy Reese, Mexico, 2067")
- Terminator series: Skynet is a malevolent, megalomaniacal AI, who managed to gain sapience and became paranoid, thinking of humanity as a threat. Taking control over the nuclear warheads, Skynet launched them upon the world, killing billions and reducing the world to ruins. Creating the killer machines, Skynet used them to hunt down and kill any survivors as well as try to destroy the human resistance. Constantly sending Terminators to the past to kill John Connor, the future leader of the human resistance, Skynet tries to keep the future of the Earth as a post-apocalyptic nightmare, leading to the divergence in timelines after the first two films:
- Rise of the Machines & Salvation: Sending its newest model to the past to kill John Connor and his future wife, Kate Brewster, Skynet also tried to have its Terminator activate it in the past, while it itself manipulates the humans, who created her, to give it control of all technology and weaponry, which it used to massacre all staff inside the laboratory and launch missiles across the world. In the future, Skynet has its Harvesters collect humans, young and old, whom it gathers in its concentration camps, where they are experimented on and then slaughtered. Using Marcus Wright, whom it transformed into a cyborg, to lure Kyle Reese and John Connor to itself in an attempt to destroy the resistance, Skynet then tries to trick the remaining humans into wiping themselves out.
- Genisys: Disappointed that its machines are unable to destroy the resistance, Skynet captures countless humans and infects them with machine-phase matter in an attempt to turn them into its newest Terminators, leading to many of them dying in agony. Tricking humans into believing they destroyed it, Skynet takes the form of a human and names itself Alex and infiltrates the resistance, killing them all except John Connor, whom it manages to transform into its new Terminator and brainwash him to serve it. Sending Connor to the past to create an operating system known as Genisys, which makes people too reliant on technology, Skynet plans to use the new system to completely destroy humanity.

As he tracks down Hollister, he offers him the disk with all the data they need to create Skynet, hoping to get rich from that scheme, despite knowing that billions of humans will be killed by their actions in the future, with Hollister agreeing, completely apathetic to the destruction of the world that will occur.
