Post-humans are enhanced individuals who appear in Ghost in the Shell: SAC_2045. They are individuals with cyberbrains who have been fundamentally transformed on a mental level by an unknown process, giving them unprecedented intelligence, cognitive and hacking speed, and focus while altering their personalities. Both full-body cyborgs and individuals who had mostly organic bodies aside from a cyberbrain were affected. The cause of the post-human phenomenon currently remains a mystery; what is known is that all identified post-humans suffered from fevers around the same time, after which they all completely ceased to appear in any cybernetic surveillance recordings or cybernetic observation from then on.
Their motivations and goals are unknown, but post-humans appear to bear a great animosity towards normal humans. Post-humans instigated the Synchronized Global Default in 2044, and amid the Sustainable War they have also materially supported raider attacks, assassinated government officials, and even attempted to launch nuclear weapons at cities. In 2045, the American Empire hired Public Security Section 9 to investigate the post-human phenomenon.
Becoming a post-human appears to involve a dramatic transformation of an individual's cyberbrain, to the point that diving into a post-human's mind can be deleterious to the diver, as Motoko Kusanagi discovered when dealing with Patrick Huge. Kusanagi ordered Saito to execute Huge to prevent the dive from irreversibly damaging her ghost. The transformation itself is preceded by a fever, possibly a physical sign of the individual's cyberbrain overclocking and overheating during the process.
A post-human's intelligence and cognitive speed are increased to a level far beyond that of a normal human or cyborg, allowing them to make extremely complex calculations almost instantaneously. This is sufficient for individuals with even minimal cyberization to become fearsome opponents in combat. While fighting Patrick Huge, the members of GHOST were initially unable to land a single shot on him because he was able to calculate bullet trajectories and how to avoid them with the minimal necessary amount of physical effort before the bullets were fired. He was also able to simultaneously hack and control his robot maids to distract his attackers and block bullets. Huge was not invincible, however, as Kusanagi was able to maim his hand in hand-to-hand combat, though he exhibited no pain response despite only having a cyberbrain and no other modifications. Also, he was able to perfectly performed repeated flips despite the aforementioned injury, indicating increased coordination and motor control. Furthermore, Gary Harts demonstrated an unstoppable hacking ability after he became a post-human and attempted to launch nuclear weapons at Moscow, simultaneously hacking dozens of his fellow soldiers and incapacitating them as he made his way to the ICBM control room.

Post-Human Vulnerabilities :
There would appear to be several weaknesses and vulnerabilities with Post-humans.
- Analog Technology: Post-human stealth is useless against analog technology, as seen with Sanji Yaguchi being caught on an old, nondigital camera that uses film.
- Tachikoma Sensors/Vision: In "Nostalgia" it would seem that Tachikoma's are unhindered by Post-human stealth, they saw Togusa leaving, where Batou didn't.
- Trauma: Trauma seems to disable the Post-human Stealth and other abilities, depending on how bad said trauma is, as seen with Gary Harts.
- Closed Networks: Seem to cut off the Post-humans's ability to hack, and act like a air-gap, the Post-human has to "leak" code to unsuspecting people to infect a closed network.
- Body of Flesh: Without a cyberbrain or other cybernetic implants, it would seem that post human abilities are negated, excluding the Post-human's physical power and agility.
- Teamwork: From what is seen so far, all Post-humans work alone, and every instance of them being taken down, involved more than one person working together for this end.
- Unknown Observation: It seems that if the Post-human is unaware of being observed, their "Stealth" is useless.
- Willing Observation: As demonstrated with the Prime Minister of Japan, and his father in law, it would seem, as if Post-humans can pick and choose who can see them or not. Though this is less of a vunrability and more of a exception to the "No longer can be observed by tech" Rule.
